实时监测技术是冷链物流中的关键技术,本文针对冷链物流环节实时监测的需要,基于北斗和百度地图提供的定位、测速的开放服务,以及无线传感器网络,设计出能有效监控冷链物流运输全过程的系统。该系统实现的超低功耗测量终端,具有对车厢内的温湿度进行检测和无线传输的功能;基于北斗定位的无线网关系统,具有对车辆状态的监控以及监控信息的转发和传输功能;基于GIS技术的服务器系统具有车辆信息在地图中显示的功能。
Real-time monitoring technology is the key technology in cold chain logistics. In this paper, according to the need of real-time monitoring of cold chain logistics, based on the open service of positioning and speed measurement provided by Beidou and Baidu map, and wireless sensor network, The whole process of transportation system. The ultra-low power measurement terminal realized by the system has the function of detecting and transmitting the temperature and humidity in the cabin. The wireless gateway system based on the BeiDou positioning has the functions of monitoring the vehicle status and forwarding and transmitting the monitoring information. GIS technology server system has the vehicle information displayed in the map function.
