需求：领导要求分析服务日志，计算出各个设备的在线时长，在线率，设备使用率等。
服务日志格式为：
2018-03-01 00:13:52,815 [protocol.handler.1][INFO] - cn.testin.trans.controller.req.script.HeartBeat.deviceLog---{"sdcardWriteable":0,"deviceAction":1,"sdcardAvail":10113417216,"wifiSsid":"testin03_default","rootEnable":0,"deviceid":"863563023966636","networkState":1,"errorMsg":"","minicapEnable":1,"deviceState":1,"romAvail":1655619584,"rpiid":"localhost","networkType":1,"ramAvail":1488954688,"debugMode":1,"errorCount":0,"batteryLevel":100}
以上标红部分：
deviceid: 为设备id， networkState:为网络状态，该值有1、0两个值 deviceState:为设备状态，该值有0、1、2三个值
