针对我国农产品物流技术落后、运输过程中农产品损失率高以及物流运输车中无检测系统等不足,以短距离无线技术为基础,提出了一种无线网络系统,利用CRM2400模块实现运输车多点温度数据采集传输.给出了系统设计原理、主要接口电路、通信协议和软件流程图.系统实用效果良好.%Aim at the disadvantages of backward of farm product logistics technique, high loss rate of farm product during transportation process and less inspecting system in transport vehicle in our country, a wireless network system was proposed based on CRM2400 module. Acquired temperature data of multiple points in a transporter vehicle were transmitted using the modules. The system's design principle, the main interface circuit, the communication protocol, and software working flowchart were given. The achieved system worked well.
