Building anti-radar design standard

First, the building anti-radar classifies the anti-radar building category which pointed out explicitly to the standard, may apply mechanically directly. In the standard to some buildings only pointed out that is bigger than estimate thunder stroke number of times XX/every year, but belongs to two kinds or three kind of anti-radar buildings. Regarding these stipulations, only depends on the direct-viewing feeling and the experience in the design, cannot determine explicitly its building respective anti-radar category, causes to make two kinds anti-radar to make three kinds by mistake, should make three kinds anti-radar, but has not done, the result is to the building which completes creates certain hidden danger. This has the necessity according to the local annual mean thunderstorm day and the building locus geography, the geological soil, the meteorological environment and so on conducts the detailed research and makes the corresponding computation, determines the anti-radar rank.
For example: Under Jinan area Td=26.3 K=2 environment according to formula: N=0.024k · Td1.3 · Ae in the formula: N- building estimate thunder stroke number of times (/year) The K- correction factor (according to newly built building locus's geography, environment decides) Td- annual mean thunderstorm day Ae- and the building truncation receives the same thunder stroke number of times equivalent area (km2)
Calculates the length 100 meters, the width 25 meters, above two (H≥9 rice) the provincial level work building must make two kind of anti-radar. If through the computation, this kind of building actual does not make three kinds anti-radar or does not do is possible. From this sees, carries on the overall evaluation to some peculiar circumstance's building and makes the corresponding computation is very essential. the two, anti-radar electric inductions and the thunder electric waves invade the against long jab thunder the measure, the general layout personnel are very explicit. But, along with the technical development, electronic installation's popularization, the anti-radar electric induction and the thunder electric wave invasion must be clear in the design, and consummates gradually forms an anti-radar network. when the 1. thunder and lightning induces - the thunder discharge, has the electrostatic induction and the electromagnetic induction on the nearby conductor, it possibly causes between the metal part to produce the spark. Therefore is protected in building's metal earth, is the anti-radar electric induction key measure. First, completes the equipotential joint. To one, two kind of anti-radar buildings in parallel or overlapping placing metal pipeline, when its clear distance is smaller than 100mm, should use Jin Shuxian to bridge, is prevents the potential difference which the electromagnetic induction creates to be able the small gap breakdown, but produces the electric spark, every other ≤30m completes the earth. the 2. thunder electric wave invasion - as a result of the thunder and lightning to the air line either the metal pipeline's function, the thunder electric wave possibly along these pipeline invasion room, endangers the personal safety or damages the equipment. Therefore, completes the terminal the anti-radar protection, completes the equalizing ring and against flank attack thunder is the anti-radar electric wave invasion key measure. First, two kind of anti-radar construction low pressure coil in entire line uses buries straight said that is built on stilts the line introduces when the indoors many in a 15m section should trade the electric cable (metal armoring electric cable to bury straight, protective covering electric cable puts on steel pipe) the buyer, and is being built on stilts with the electric cable trades meets place completes the lightning protection protection. Two kind of anti-radar constructions work as the air line direct introduction, besides in the residence place addition arrester, and completes the buyer installment iron stock the earth, approaches on building's two telephone pole's iron stock also to complete the earth, and the impact earth resistance ≤30Ω, all weak electricity coil in's protection should with the strong electricity coil. The anti-radar building must complete the equalizing ring and against flank attack thunder protection. Equalizing ring from three starts, between link vertical range ≤12m, all downleads, building's metal structure and the hardware reliably connects with the link, the equalizing ring may use in the structure grid's steel bar (steel bar to link up ring circuit). A kind anti-radar constructs above 30m, two kinds anti-radar construct above 45m, three kinds anti-radar construct above 60m, must complete against flank attack thunder protection, makes one week level along the building outer wall to evade the mine belt, between the belt and the belt the vertical range ≤6m, in the outer wall all metal parapet, the windows and doors with evade the mine belt to connect reliably, evade the mine belt to connect reliably again with the downlead. The vertical placing's metal pipeline and the metal peak and the bottom end and the antimine device reliable connection, the goal lies in the equipotential, because and the both sides connection causes it to form the parallel with the downlead, causes the thunder electric current news fast to enter. three, anti-radar electric currents after downlead and when grounding has the high electric potential completes against long jab thunder, the thunder electric wave invasion and the thunder and lightning to the hardware or electrical line counter-attack measure induces, is not a complete anti-radar design. Because, in the building mostly uses together the grounding at present, when thunder long jab in this building antimine device, the supposition flows through approaches the low pressure electric installation place grounding the thunder electric current is 20KA, when impact earth resistance =1Ω, in the grounding the electric potential elevates is 20KV, but the general indoor low pressure installment bears the striking potential most to be high is 8KV. Its result causes the low pressure electric installation insulation to be weak place is possibly penetrated creates the short circuit, has the fire, to damage the equipment, this is very dangerous. Therefore, gives the enough value in the design, realizes omni-directionally, the multi-level anti-radar networks to the anti-radar building, causes the thunder and lightning the influence to reduce to the building is smallest.when building for high-pressured coil, high-pressured, the low pressure side each on supposes the arrester, with protects by the high-pressured coil in thunder and lightning and the operation (circuit breaker movement, throws cuts big electric motor and condenser bank and so on) the overvoltage. The electronic installation are many and the important construction, installs the overvoltage protection again in the low pressure power distribution branch, does for the reserve protection, mainly uses in further suppressing after the pretage protection limit on the surplus overvoltage and the power line the overvoltage which produces by the induction or the coupling.when building for low pressure coil, installs the overvoltage protector in the power source total coil in place. four, about meet dodges to meet dodges - the direct truncation the lightning rod which is struck by lightning, to evade the mine belt (line), the lightning protection network, as well as serves as the metal roofing which and the steel work meets dodges and so on. In many buildings, the roofing for on person roofing, is high to the artistic request, according to the conventional procedure, clearly spreads the lightning protection network with the garden steel to do meets dodges is artistic on the influence, this standard to two kind of anti-radar buildings in two, three, eight, nine section of building pointed out that with in the reinforced concrete roofing, Liang, column's steel bar achievement meets suitably dodges, in the practical application, may use in the roofing parapet wall the capping steel bar to do meets dodges, is higher than the roofing each kind of iron stock to with the capping steel bar reliable welding (when construction must pay attention to coordination), the capping steel bar with makes in downlead's column four corner postsThe muscle completes the reliable electrical connection. This procedure must have the concretes fragment which regularly to the thunder stroke the possibility creates or withdraw carries on the service. five, earth body - bury in the soil or the concrete foundation does drifts with the conductor about earth body the . In the practical application, the big project uses in the foundation the steel bar to make the earth body generally, and uses the union earth body, the earth resistance value to request slightly ≤1Ω. But in some have the basement, in half basement construction, at the construction uses the waterproofing material to construct the ledger wall to make waterproof processing. At present, uses the waterproofing material has the very good insulating property, therefore, makes the earthed pole directly to this kind of building using the foundation steel bar, had the possibility not to be able to satisfy the project docking earth resistance request, must direct from the column muscle downlead place, one week made in the closed artificial earth body and the foundation along the building slope protection outside the steel bar and uses, like this could achieve the satisfactory earth resistance value.
译文： 建筑物防雷设计规范

一、建筑物的防雷分类
对规范中明确指出的防雷建筑物类别，可直接套用。规范中对有些建筑物仅指出大于预计雷击次数XX次/每年，而归属二类或三类防雷建筑物。对于这些规定，在设计中仅凭直观感觉和经验，就不能明确确定其建筑物所属防雷类别，使应做二类防雷误做成三类，应做三类防雷而没做，结果是对建成的建筑物造成一定的隐患。这就有必要据当地的年平均雷暴日及建筑物所在地的地理、地质土壤、气象环境等进行详细的研究并做出相应的计算，来确定防雷等级。
例如：在济南地区Td=26.3 K=2的环境下
据公式：N=0.024k·Td1．3·Ae
式中：N—建筑物预计雷击次数(次/年)
K—校正系数(据新建建筑物所在地的地理、环境而定)
Td—年平均雷暴日
Ae—与建筑物截收相同雷击次数的等效面积(km2)
计算出长100米、宽25米，两层以上(H≥9米)的省级办公建筑物就要做二类防雷。如果不通过计算，这类建筑物实际中做成三类防雷或不做都是有可能的。由此看出，对一些特殊情况下的建筑物进行综合考虑并做出相应的计算是非常必要的。
二、防雷电感应和雷电波侵入
防直击雷的措施，一般设计人员都很明确。但是，随着科技的发展，电子设备的普及，防雷电感应和雷电波侵入在设计中也必须明确，并逐步完善形成一个防雷网络。
1.雷电感应—雷电放电时，在附近导体上产生的静电感应和电磁感应，它可能使金属部件之间产生火花。因此被保护建筑物内的金属物接地，是防雷电感应的主要措施。首先，是做好等电位联结。对一、二类防雷建筑物内平行或交叉敷设的金属管道，其净距小于100mm时，应采用金属线跨接，是防止电磁感应所造成的电位差能将小空隙击穿，而产生电火花，每隔≤30m做好接地。
2.雷电波侵入—由于雷电对架空线或金属管道的作用，雷电波可能沿着这些管线侵入屋内，危及人身安全或损坏设备。因此，做好进线端的防雷保护，做好均压环及防侧击雷是防雷电波侵入的主要措施。 一、二类防雷建筑低压进线全线采用直埋地引入，将线路架空引入户内时不少于15m的一段应换电缆(金属铠装电缆直埋地，护套电缆穿钢管)进户，并在架空与电缆换接处做好避雷保护。二类防雷建筑当架空线直接引入时，除在入户处加装避雷器，并将进户装置铁件做好接地外，靠近建筑物的两根电杆上的铁件也应做好接地，且冲击接地电阻≤30Ω，所有弱电进线的保护应同强电进线。防雷建筑要做好均压环及防侧击雷保护。均压环从三层开始，环间垂直距离≤12m，所有引下线、建筑物的金属结构和金属设备均与环可靠连接，均压环可利用结构圈梁内的钢筋(钢筋必须贯通成环路)。一类防雷建筑30m以上，二类防雷建筑45m以上，三类防雷建筑60m以上，要做好防侧击雷保护，沿建筑物外墙做一周水平避雷带，带与带间垂直距离≤6m，外墙上所有金属栏杆，门窗均与避雷带可靠连接，避雷带再与引下线可靠连接。竖直敷设的金属管道及金属物的顶端和底端与防雷装置可靠连接，目的是在于等电位，并且由于两端连接使其与引下线形成并联线路，使雷电流更讯速的入地。
三、防雷电流经引下线和接地装置时产生高电位对金属设备或电气线路反击的措施
做好防直击雷、雷电波侵入和雷电感应，还不是一个完整的防雷设计。因为，目前建筑物内大多采用共同接地装置，当雷直击于本建筑物防雷装置时，假设流经靠近低压电气装置处接地装置的雷电流为20KA，当冲击接地电阻=1Ω时，接地装置上电位升高为20KV，而一般室内低压装置的耐冲击电压最高为8KV。其结果就使低压电气装置绝缘较弱处可能被击穿而造成短路，发生火灾、损坏设备，这是非常危险的。因此，在设计中给予足够的重视，对防雷建筑物实现全方位、多层次的防雷网络，使雷电对建筑物的影响减至最小。
建筑物为高压进线时，高、低压侧各相上均设避雷器，用以防护由高压进线的雷电和操作(断路器动作，投切大电动机和电容器组等)过电压。电子设备较多且重要的建筑，在低压配电支线上再装设过电压保护，做为后备保护，主要用于进一步抑制经前置保护限制后的剩余过电压和电源线上由感应或耦合产生的过电压。
建筑物为低压进线时，在电源总进线处装设过电压保护器。
四、关于接闪器
接闪器—直接截受雷击的避雷针、避雷带(线)、避雷网，以及用作接闪的金属屋面和金属构件等。在许多建筑物中，屋面为上人屋面，对美观要求较高，按常规做法，用园钢明敷避雷网做接闪器就影响美观，本规范对二类防雷建筑物中二、三、八、九款中的建筑物指出宜用钢筋混凝土屋面、梁、柱内的钢筋作为接闪器，实际应用中，可采用屋面女儿墙内的压顶钢筋做接闪器，高出屋面的各种铁件要与压顶钢筋可靠焊接(施工时要注意配合)，压顶钢筋与做引下线的柱内四角柱筋做好可靠的电气连接。这种做法要定期对雷击有可能造成的混凝土碎片或脱开进行维修。
五、关于接地体
接地体—埋入土壤中或混凝土基础中作散流用的导体。实际应用中，一般较大工程都利用基础内钢筋做接地体，并采用联合接地体、接地电阻值要求小≤1Ω。但在一些带有地下室、半地下室的建筑中，土建上都采用防水材料对建筑底板做防水处理。目前，所采用的防水材料都具有很好的绝缘性，因此，对这类建筑直接利用基础钢筋做接地极，就有可能满足不了工程对接地电阻的要求，要从柱筋引下线处外引，沿建筑物护坡外一周做闭合人工接地体与基础内钢筋并用，这样能达到较满意的接地电阻值。

手要断了~~希望你能满意~ 参考技术A Defend the change of thunder product
When people know that the thunder is a kind of electricity phenomenon after, to the adoration of the thunder and lightning with fear for the gradual disappearance, and start with the taste of science come from new observation the natural phenomena of this magic, hope to make use of or control a thunder and lightning activity to bring benefit to mankind.More than 200 year agos Franklin led off on the technique to start a challenge toward the thunder and lightning, he invent of the lightning rod may be regarded as to at the earliest stage defend a thunder product and this product name almost has already been know by the all people today.In fact, Franklin while invent lightning rod is think metals lightning rod of point of turn on electricity a function can synthesize the electric charge in thunder cloud, make thunder cloud and the electric field of the earth be as low as the level that can't broke through air, avoided strike by lightning thus of occurrence, so the then lightning rod must request to be sharp.But afterwards study enunciation:The lightning rod is the occurrence of the unavoidable thunder of, the reason that it can prevent°from a thunder is because the Gao is towering to sign of the lightning rod changed atmosphere electric field, make thunder cloud of certain scope always turn on electricity toward the lightning rod, be also say lightning rod be just than it surroundings of other objects more easily connect Shan thunder and lightning, the lightning rod is strike by lightning medium but other objects be protect, this be the defend of lightning rod thunder principle.Further of the research express the connect of lightning rod Shan function almost have something to do with its height, but have nothing to do with its shape, be say that the lightning rod isn't necessarily sharp.Defend a thunder technique realm to know together as now this type of defend thunder device for connect a Shan machine.
The widespread usage of electricity promoted to defend the development of thunder product and be a high pressure power grid to provide motive and illuminate for the thousand 10000, thunder and lightning also a great deal of bane high pressure lose to change to give or get an electric shock an equipments.The high pressure line installs Gao, be apart from long, cross geography complications, is strike by lightning easily medium.The protection scope shortage of the lightning rod with protect up to thousand power lines, so avoid thunder line as to protect high pressure line of new connect a Shan machine to emerge with the tide of the times.After the high pressure line acquire a protection, the hair linked with high pressure line, go together with electricity equipments to be still conduct electricity to press damage, people discover this is because"respond thunder" is play tricks.(Respond the thunder is to respond the metals conductor of neighborhood because of keeping shot thunder to turn on electricity in, respond the thunder can pass 2 kinds to differently respond way incursion conductor, one is an electrostatic induction:When the electric charge in thunder cloud accumulates to gather, neighborhood of the conductor will also respond up the contrary electric charge and be a thunder to turn on electricity, the electric charge in thunder cloud quickly releases, and the conductor Central plains come to is tie up by thunder cloud electric field of the static electricity will also follow conductor fluxion to look for to release passage, will become electricity pulse in the electric circuit.
Two is an electromagnetic induction:When thunder cloud turn on electricity, the thunder and lightning of quick variety flows to around produce to strongly change in a sudden an electromagnetism field at it and produce very high feeling to living electromotive force in the conductor of its neighborhood.Study enunciation:The wave that the electrostatic induction method cause flows out the wave that the several cause at the electromagnetic induction to flow out.)The thunder and lightning is on-line to start to respond an electricity to flow out in the high pressure, and follow to lead line to spread with it connect with each other of hair, go together with electricity equipments, be these bear of equipmentses to press lower hour will be responded thunder to damage, for repress to lead line in of give or get an electric shock to flow out, people invented a circuit lightning arrester.
The circuit lightning arrester in earlier period is a liberal air cleft.The air brokes through electric voltage very high, about the 500 kVs/m, but after it was broke through by the high electric voltage the low pressure of only several ten Fus.This characteristic people who make use of air designed the circuit lightning arrester in earlier period and lead 1 line of a carry connect on the power line, another lead line of on carrying to connect ground, 2 lead line of another a carry to be separated certain distance constitute air cleft of two electrodes, cleft distance made sure a broke through of lightning arrester electric voltage, broke through the electric voltage should be slightly high at the work electric voltage of power line, so be electric circuit to normally work, the air cleft is equal to open a new road, will not influence the normal work of circuit.While conducting electricity to press invade, the air cleft is broke through, conduct electricity to press quilt Qian to arrive very low level, conduct electricity to flow to also leak to put into the ground through an air cleft and carried out a lightning arrester to protect circuit.Open the cleft contains too many weakness, if broke through electric voltage is influence by environment greatly;Air's turn on electricity will oxidize electrode;Air electricity arc-shaped needs to through many communicate that the period then can extinguish Hu after become, this may result in the lightning arrester break down or the circuit break down.Hereafter developped the air of to turn on electricity a tube, tube type lightning arrester, Ci to blow a lightning arrester to to a large extent overcome these troubles, but they are still the principles that the establishments turn on electricity in the air up.The air turns on electricity the proper weakness of a lightning arrester:The impact brokes through electric voltage Gao;Postpone while turn on electricity longer(the μ s class);The remnants presses a form steep.(the dV/dt be more big)These protections ability that the weakness comes to a decision air to turn on electricity a lightning arrester an equipments to the sensitive electricity aren't strong.
The semi-conductor technical development provided to defend the thunder new material for us, for example steady press a tube, it the Fu-Anne's characteristic match circuit to defend a thunder request, just it passes the ability that the thunder and lightning flow weak, make common of steady press a tube can't directly used to a lightning arrester.The valve type that the semi-conductor lightning arrester in earlier period is make into with carborundum material lightning arrester, it have with steady press the Fu-Anne's characteristic of the tube likeness, but pass the ability that the thunder and lightning flow very strong.However very quick people discovered metals oxide again the semi-conductor change Zu machine(MOV), it the Fu-Anne's characteristic be better, and have to respond to time quickly, flow to have great capacity etc. many advantages.Therefore, currently widespread adoption MOV circuit lightning arrester.
Along with the development of correspondence, and then produced many lightning arresters which used for corresponding by letter circuit, because of being deliver by correspondence circuit the stipulations of parameter, this lightning arrester wants to consider that the influences, such as electric capacity and electricity feeling...etc. delivers the index signs of parameter.But it defends thunder principle and MOV basic consistent.
A, connect Shan function to point a realization to connect the condition that the Shan function should have, include a form(lightning rod, avoid thunder to take and avoid a thunder net) of connect the Shan machine, bear to flow to bear the ability of press and connect Shan effect and build price and connect Shan machine and the esthetics unity of the building etc. in a row.
B, reposition of redundant personnel influence the guide line log out to the reposition of redundant personnel effect of influence.Lead to log out of thick thin directly influence reposition of redundant personnel effect with amount, lead to log out to have another, each one leads to log out to pass of the thunder and lightning flow small, it responds scope small.The distance which leads to log out its mutually shouldn't be small at the provision in the norm.When the building is very high, lead to log out very long time, should in the building of the middle part's increment all presses wreath to lead by let up to log out of the electricity electric voltage decline.This not only can with the reposition of redundant personnel, and can also lower to counter-attack electric voltage.
C, the balanced electric potential make each parts in the building all become an equal electric potential, then etc. electric potential.If the structure reinforcing bar in the building can link with various metals constitution and the metals pipelineses unify of conduct electricity a body, certainly will not produce different electric potential inside building, so can promise will not produce counter-attack and endanger contact electric voltage or stride electric voltage of Human body safety inside building, to keep the micro-electronics equipments of the pulse interference of the thunder and lightning electromagnetism from have also a very big advantage.The building of reinforced concrete structure most has a realization etc. the condition of the electric potential, because it all of the big parts of internal structure reinforcing bar is to naturally weld or colligation together.In order to satisfy a request of defend the thunder device, should there is destination connect Shan device and beam, plank, pillar and foundation to dependablely weld, colligation or take to connect together, in the meantime again various metals equipments and the metals pipeline with it weld or the card connect together, this makes the whole building become good etc. electric potential a body.
D, shield the main purpose that the function shield is make inside building of correspondence equipments, computer, precise instrument and automatic control system don't need encounter thunder and lightning electromagnetism the bane of the pulse.These facilitieses in the building, not only will be subjected to electromagnetism interference while defending thunder device to connect Shan, and intelligent because of they sex Gao and bear to press level low, sometimes nearby thunderclap or connect Shan, will also be subjected to the influence that the electromagnetism of thunder and lightning wave radiate, even will also be subjected to from the electromagnetic wave for spread when other buildings connect Shan of influence.Therefore, we should as far as possible make use of the reinforcing bar in the reinforced concrete structure, namely the reinforcing bar in the plank, wall noodles, and beam, pillar of the building hinterland plank, crest, make it constitute a net cage of hexahedron, namely the cage type avoid a thunder net and carry out to shield thus.Because of the dissimilarity of structure structure, inside wall with the reinforcing bar in the building plank have Shu is airtight, when the reinforcing bar density isn't enough, design a person should press the density that the different demand of various equipments increases a mesh.Goodly shield to not only make etc.'s electric potential and reposition of redundant personnel's these two problems solve problems with the greatest ease, but also is also the most valid measure towards defendoofing thunder and lightning electromagnetism, pulse.In addition, building of whole shield can also defend ball thunder, side shot and round the raid of shot thunder.
Five, connect the quality which connects a ground of effect of a ground of effect.Goodly connecting a ground of effect is goodlyalso one of important assurances which defends thunder success.Each building wants to consider which kind the effect which connects a place type had better with the most economic.King Xu the Sir think, when the building which is reinforced concrete structure matches a norm condition, should make use of reinforcing bar conduct and actions in the foundation to connect a ground of device.When condition or foundation coulded not reach to rule in the norm wrap in waterproof book material layer, can do for a week, the turn type connects a ground of device, but should week the turn type connect a ground of device in advance covers up in the foundation slot of outermost.(need not leave the building 3 ms outside)Connect a ground of body near the foundation inside of the reinforcing bar be advantageous to balanced electric potential, can also save in the meantime for dig the manpower and material resources that deep ditch cost.Dig again after the foundation complete work the deep ditch then easily influences a basal stability. Mix structure building to the wood structure and the brick, have to do independence to lead to log out and adopt independence to connect a place type.When soil electric resistance the rate be big, the usage connects ground very more, can also do a surroundings type to connect a ground of device.Because the week turn type connects a ground of impact resistance of device small in independently connect a ground of impact resistance of device, and be advantageous to the ground electric potential which improves inside building to distribute, let up stride electric voltage.Taking drilling a hole to deeply cover up effect of connect a ground of pole(about the 4~12 ms) as when adopt the independent type connects a place type had better, the deep bore connect a ground of water level with underground pole easy reach, and can reduce to connect use of a ground of pole amount of steel.

E, the thunder and lightning wave invade
Thunder and lightning wave the form which invade an intelligence building contains 2 kinds, 1 kind keeps shot thunder, another is to respond thunder.Generally speaking, the possibility which keeps the electronics equipments of intelligence building universe in the shot thunder is very small, usually need not install the equipments that the protection keeps shot thunder.Respond the thunder is flowed output strong electromagnetism field variety and conductor by the thunder lightning flash to respond a conduct electricity of to press and conduct electricity to flow a formation thunder.Respond the thunder invades electronics equipments and calculator system to mainly have the following three paths:
(1)The ground electric potential of thunder and lightning counter-attacks electric voltage to pass to connect a ground of body to invade.

(2)From communicate power supply power supply the circuit invade.

(3)It is invade by the correspondence signal circuit.Ignore is to pass which form, which path invade, will make electronics equipments and calculator system be subjected to damage or serious interference of different degree.

The intelligence mansion is generally and all a type of building, should build up comprehensive connect a ground of system, connect a ground of electric resistance to be no bigger than one Ω .Design in the building crest from avoid thunder to take, lightning rod or mixture constitute of connect a Shan machine, make use of steel pillar or sign the reinforcing bar in the pillar as to defend thunder to lead to log out, and and the foundation reinforcing bar of building, beam reinforcing bar, the metals frame conjunction gets up, become to shut to match good farad cage and construct inside the Shu toward the metals piping should each time all press of the 3 F and turn beam wreath connect with each other, all press wreath should with defend thunder device ad hoc lead to log out connect with each other.When building is more than 30 meters high, in response to 30 meters and the railing on above part of outside walls, the metals doors and windows wait a bigger metal direct or through metals doors and windows cover up an iron with defend thunder device a conjunction.The intelligence is various exchanges inside the mansion, the direct current equipments is numerous, the circuit maneuvers interleave, should exchanges work in the building ground, safe protection ground, direct current work ground, defend thunder to connect ground and the cage good conjunction of the building farad, become an etc. electric potential body, avoid connecting the existence potential difference of the of a ground of line, respond to conduct electricity reason of press the creation by cancellation.

Thunder and lightning in order not to from communicate power supply power supply the circuit invade, can in the high pressure cabinet of go together with the electricity of the change of mansion of each mutually install the first degree protection of lightning arrester conduct and actions, install a valve door a type to defend thunder device as a second degree protection in the low-pressure cabinet, in order to prevent thunder and lightning irruptive go together with of mansion electricity system.For careful rise to see, can install power supply to avoid thunder box as in the power supply of each layer of mansion go together with the electricity box x-rated protection and will go together with an electricity box of the metals outer shell and defend of mansion thunder connect a ground of system credibility conjunction.

The correspondence circuit in the intelligence mansion's have another is take by the comprehensive cloth line system.The comprehensive cloth line system constitutes to°from six statures systems:

(1)The buildings sub- system.

(2)Equipments sub- system.

(3)Manage sub- system.

(4)Perpendicular trunk line sub- system.

(5)The level trunk line sub- system.

(6)Work the area sub- system.
Our underneath is once analytical to comprehensive the cloth line defend of system thunder protection.本回答被提问者采纳 参考技术B 用金山快移

参考技术A Getting Started with µVision2
The Keil Software 8051 development tools listed below are programs you use to compile your C code, assemble your assembly source files, link and locate object modules and libraries, create HEX files, and debug your target program.
 µVision2 for Windows™ is an Integrated Development Environment that combines project management, source code editing, and program debugging in one single, powerful environment.
 The C51 ANSI Optimizing C Cross Compiler creates relocatable object modules from your C source code.
 The A51 Macro Assembler creates relocatable object modules from your 8051 assembly source code.
 The BL51 Linker/Locator combines relocatable object modules created by the C51 Compiler and the A51 Assembler into absolute object modules.
 The LIB51 Library Manager combines object modules into libraries that may be used by the linker.
 The OH51 Object-HEX Converter creates Intel HEX files from absolute object modules.
 The RTX-51 Real-time Operating System simplifies the design of complex, time-critical software projects.
Software Development Cycle
When you use the Keil Software tools, the project development cycle is roughly the same as it is for any other software development project.
1. Create a project, select the target chip from the device database, and configure the tool settings.
2. Create source files in C or assembly.
3. Build your application with the project manager.
4. Correct errors in source files.
5. Test the linked application.

LIB51 Library Manager
The LIB51 library manager allows you to create object library from the object files created by the compiler and assembler. Libraries are specially formatted, ordered program collections of object modules that may be used by the linker at a later time. When the linker processes a library, only those object modules in the library that are necessary to create the program are used.
BL51 Linker/Locator
The BL51 linker creates an absolute object module using the object modules extracted from libraries and those created by the compiler and assembler. An absolute object file or module contains no relocatable code or data. All code and data reside at fixed memory locations. The absolute object file may be used:
 To program an EPROM or other memory devices,
 With the µVision2 Debugger for simulation and target debugging,
 With an in-circuit emulator for the program testing.
µVision2 Debugger
The µVision2 symbolic, source-level debugger is ideally suited for fast, reliable program debugging. The debugger includes a high-speed simulator that let you simulate an entire 8051 system including on-chip peripherals and external hardware. The attributes of the chip you use are automatically configured when you select the device from the Device Database.
The µVision2 Debugger provides several ways for you to test your programs on
real target hardware:
 Install the MON51 Target Monitor on your target system and download your program using the Monitor-51 interface built-in to the µVision2 Debugger.
 Use the Advanced GDI interface to attach use the µVision2 Debugger front end with your target system.
Monitor-51
The µVision2 Debugger supports target debugging using Monitor-51. The monitor program resides in the memory of your target hardware and communicates with the µVision2 Debugger using the serial port of the 8051 and a COM port of your PC. With Monitor-51, µVision2 lets you perform source-level, symbolic debugging on your target hardware.
RTX51 Real-Time Operating System
The RTX51 real-time operating system is a multitasking kernel for the 8051 microcontroller family. The RTX51 real-time kernel simplifies the system design, programming, and debugging of complex applications where fast reaction to time critical events is essential. The kernel is fully integrated into the C51 Compiler and is easy to use. Task description tables and operating system consistency are automatically controlled by the BL51 linker/locator.
C51 Optimizing C Cross Compiler
The Keil C51 Cross Compiler is an ANSI C Compiler that was written
specifically to generate fast, compact code for the 8051 microcontroller family.
The C51 Compiler generates object code that matches the efficiency and speed
of assembly programming.
Using a high-level language like C has many advantages over assembly language
programming:
 Knowledge of the processor instruction set is not required. Rudimentary knowledge of the memory structure of the 8051 CPU is desirable (but not necessary).
 Details like register allocation and addressing of the various memory types and data types is managed by the compiler.
 Programs get a formal structure (which is imposed by the C programming language) and can be divided into separate functions. This contributes to source code reusability as well as better overall application structure.
 The ability to combine variable selection with specific operations improves program readability.
 Keywords and operational functions that more nearly resemble the human thought process may be used.
 Programming and program test time is drastically reduced.
 The C run-time library contains many standard routines such as: formatted output, numeric conversions, and floating-point arithmetic.
 Existing program parts can be more easily included into new programs because of modular program construction techniques.
 The language C is a very portable language (based on the ANSI standard) that enjoys wide popular support and is easily obtained for most systems.
Existing program investments can be quickly adapted to other processors as needed.
Code Optimizations
The C51 Compiler is an aggressive optimizing compiler that takes numerous steps to ensure that the code generated and output to the object file is the most efficient (smallest and/or fastest) code possible. The compiler analyzes the generated code to produce the most efficient instruction sequences. This ensures that your C program runs as quickly and effectively as possible in the least amount of code space.
The C51 Compiler provides nine different levels of optimizing. Each increasing level includes the optimizations of levels below it. The following is a list of all optimizations currently performed by the C51 Compiler.
General Optimizations
 Constant Folding: Constant values occurring in an expression or address calculation are combined as a single constant.
 Jump Optimizing: Jumps are inverted or extended to the final target address when the program efficiency is thereby increased.
 Dead Code Elimination: Code that cannot be reached (dead code) is removed from the program.
 Register Variables: Automatic variables and function arguments are located in registers whenever possible. No data memory space is reserved for these variables.
 Parameter Passing Via Registers: A maximum of three function arguments
 may be passed in registers.
 Global Common Subexpression Elimination: Identical subexpressions or address calculations that occur multiple times in a function are recognized and calculated only once whenever possible.
 Common Tail Merging: Common instruction blocks are merged together using jump instructions.
 Re-use Common Entry Code: Common instruction sequences are moved in front of a function to reduce code size.
 Common Block Subroutines: Multiple instruction sequences are packed into subroutines. Instructions are rearranged to maximize the block size.
