In this paper, we designed a ZigBee-based vaccine cold chain transport monitoring system. It is a wireless sensor network composed by coordinators and collecting nodes, of which, the coordinator would pass the collected data on temperature, humidity and vibration, etc., on to the STM32 for the real-time display of the vaccine situation and meanwhile the STM32 would collect geographical and location information and send it, together with the above received, and all warning information, through GPRS, to the backstage upper computer for comprehensive monitoring. At the end, through testing and analysis, we demonstrated the strength of the system and its feasibility in vaccine transport environment monitoring.%医用疫苗作为一种高风险的生物药品,在其运输过程中,环境状况监测等方面智能化程度不高.针对这种情况设计了一种基于ZigBee的疫苗冷链运输监测系统,此系统以CC2530作为协调器和采集节点组成无线传感网络,再经由协调器把采集的温度、湿度、震动等传感器数据传递给STM32来实时显示疫苗环境状况,最后由STM32采集地理位置信息,然后一并将所有数据和报警信息通过GPRS传输至后台上位机进行全方位监控.经过测试和分析得出,本系统具有低成本,低功耗,组网灵活和实用性强等优点,可以广泛应用于疫苗运输环境监测领域.
