冷链物流车厢微环境感知与调控系统设计

The Information Perception and Control System of Micro-Environment Compartment in Cold Chain Logistics

研制了一种应用于冷链物流的车厢微环境感知与调控系统。系统由手持终端模块和车载测控模块两部分组成,手持终端模块通过RFID和按键设置理想环境参数和手机号码等,并与车载控制模块无线通信,车载测控模块实时检测车厢内温度、湿度、CO2含量、震动等参数,并进行短信报警和PID调控。测试结果表明,系统工作正常,性能良好。

The system of perception and intelligent control was designed,which was applied to the micro-environment compartment in cold chain logistics. The system was composed of handheld terminal module and on-board measurement and control module. The handheld terminal module can set the comfortable environment parameters,the cell phone number and so on with dash control. It also communicated with the onboard measurement and control module by radio. The vehicle control module detected the compartment parameters,such as temperature,humidity,the density of carbon dioxide,vibration,in real-time automatically. And it can alarm with SMS and PID control,if the environment parameters were beyond the range. The test results show that the system works properly with good performance.
