摘　　要：为防止货物在运输过程中腐烂变质,确保冷藏车内的环境达到食品冷冻和保鲜的条件,设计了一种冷藏车远程监控系统。整个系统监控部分由Zig Bee采集网络和GSM/GPRS数据传输两部分构成。在单片机作用下,采集节点对冷藏车内的温度、湿度、乙烯浓度和CO2浓度进行实时采集,多终端节点构成数据采集Zig Bee网络。系统通过GSM/GPRS将采集的信息传送至远程监控中心,控制中心根据设定的环境阈值,通过单片机控制执行机构对温度、湿度进行调节。若有异常,系统启动声光报警。To avoid the goods getting rot and decay, and ensure the environmental condition to meet the requirement for freezing and preservation of goods during transportation, a remote monitoring system for refrigerated vehicle was designed. The system was composed of a ZigBee network acquisition system and a GSM/GPRS data transmission system. Under the control of single chip MCU,some environmental parameters such as temperature, humidity, ethylene concentration and carbon dioxide concentration of the refrigerated truck were real-time collected by the acquisition nodes. ZigBee wireless network for data acquisition was constructed by the multi-terminal nodes. The collected data was transferred to the remote monitoring center by applying GSM/GPRS, and then temperature and humidity adjustment were implemented in line with the environmental threshold of system setting through the MCU. If there was any problem, sound and light alarm was activated by the control enter.
