The cold chain monitoring system is of great significance to the sample management of veterinary biosafety laboratories. In this paper,the composition of cold chain monitoring system was introduced,including temperature sensor,digital temperature acquisition,wireless repeater,wireless transmission system,cold chain monitoring and management system and cloud platform. Also,the functions of this system were expounded,including real-time running state supervision,real-time alarm processing,data query and analysis,and so on. It was indicated that the system was suitable for veterinary biological safety laboratories,and it could be used to monitor the temperature of cold chain equipment in each room.%冷链监控系统对兽医生物安全实验室样品管理工作具有重要意义.本文介绍了冷链监控系统的组成,包括温度传感器、数字温度采集器、无线中继器、无线传输系统、冷链监控管理系统和云平台等,阐述了该系统能够实现实时运行状态监管、实时报警处理和数据查询及分析等功能,提示该系统适用于兽医生物安全实验室,对分布在各房间的冷链设备进行温度监控.
