针对海产品运输环节实时监测的需要,利用无线传感器网络部署方便、成本低、低功耗等特点,设计出能有效监控海产品冷链物流运输全过程的系统。该系统设计实现了超低功耗测量终端,能对对车厢内的温湿度进行检测无线传输功能;实现了无线网关系统,利用北斗定位系统、加速度计、GPRS等设备实现了对车辆状态的监控以及监控信息的转发和传输功能;利用GIS技术实现了车辆在地图中的显示的服务器系统。
In order to meet the need of real-time monitoring of marine product transportation, this paper designs a system that can effectively monitor the whole process of seafood cold chain logistics transportation by utilizing the characteristics of WSN deployment, low cost and low power consumption. The system design and implementation of ultra-low power measurement terminal, the temperature and humidity inside the car can be detected wireless transmission function; the realization of the wireless gateway system, the use of Beidou positioning system, accelerometer, GPRS and other equipment to achieve the state of the vehicle monitoring As well as monitoring information transmission and transmission functions; the use of GIS technology to achieve the vehicle in the map display server system.
