程序主要功能是用C#完成一个温度传感网络监控系统，实现对各个温度传感器终端（这里我是用的单片机控制两个DS18B20检测温度SIM900 进行GPRS通信+M87获取GPS还有时间信息，比较简单可以自己开个板做）数据监控并写入数据库。
还有个客户管理系统对不同终端信息，比如用户电话，地址之类管理，也可以看各个传感器历史数据，并用VISIFIRE监视温度曲线，还有用谷歌地图查看传感器位置之类，实时查看传感器状态，传感器报修，异常传感器查询，维修记录打印.........
员工管理系统则是管理员工密码权限之类。
The main function of the program is to use C# to complete a temperature sensor network monitoring system, for each temperature sensor terminal (here I use the microcontroller to control two DS18B20 detects temperature SIM900 GPRS communication+M87 were also obtain GPS time information can own is relatively simple open a panel to do so), data monitoring and written to the . There is a customer management systems for different terminal information such as the user' s phone, address, like management, you can also see each sensor historical data, and use VISIFIRE monitor the temperature profile, as well as view the position of the sensor and the like with Google Maps, view real-time sensor status, sensor repair, abnormal sensor interrogation, maintenance records Print ......... staff management system is used to manage employee passwords and the like privileges.
