物联网通用json协议设计

网关发送
	1.上传所有数据(含告警) {"sn":"123456","time":"2020-01-06 10:57:30","data":[[设备号1, 通道号1,"湿度","值27.8"],[1,2,"温度","2"]],"alarm":[[1,1,"湿度","值27.8","上限","下限",告警产生1],[1,2,"温度","2","上限","下限",1]]}
		注：sn首次不发送,从服务器返回唯一值,以后发送时就带上sn,网关清除此值后重新生成。


服务器响应（可设置响应内容）
	1.设置上传url前缀 且 设置sn 且 校时 且 上传间隔 且 控制 且 告警策略 {"status":1,"url":"http://giot.kjxt.tech:3030?update=","sn":123456,"interval":30,"time":"2020-01-06 10:57:30","control":[2,3,"1"],"strategy_alarm":[[2,3,"上限","下限"],[2,4,"上限","下限"]]}

网关没有RTC就去掉时间由服务器生成。功能可以自由扩展。
