Abstract The system of perception and intelligent control was designed, which was applied to the microenvironment compartment in cold chain logistics. The system was composed of handheld terminal module and onboard 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 realtime 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.

冷链物流是以冷冻工艺学为基础、以制冷技术为手段的低温物流,是保证食品质量、减少食品消耗的一项系统工程。近年来随着生活水平的提高,人们对冷链物品的消费要求也在逐年增高。冷链物流一般遵循“3T”原则,即产品质量最终取决于在冷链物流中贮藏和流通时间(Time)、温度(Temperature)和产品耐藏性(Tolerance)[1]。在运输过程中,车厢微环境对于冷链物品的质量、损耗等具有重要影响,因此车厢微环境的监测、调控始终是冷链物流的重要课题。笔者采用RFID、无线通信、测控等技术,设计了一种车厢微环境感知与调控系统,能根据不同种类货品的需求,方便、快捷地设定和更改所需的环境参数,并通过多种类型传感器实时采集车厢内主要微环境参数,当车厢参数超过设定阈值时,自动向司机和管理人员报警,并提供相关控制信号及控制接口。……
