面向冷藏箱箱温的智能化监控系统研究

The Intelligent Temperature Monitoring System for Cold Container

针对冷藏箱监控系统的不足,提出一种箱温智能化监控系统。利用ZigBee无线传感器网络对箱内温度环境进行分布式检测,利用CAN总线将ZigBee网络、控制器、终端设备连接起来构成冷箱箱载系统,并选择多级信息融合和一致性检验算法计算箱内可靠温度数据,控制器采用模糊PID算法进行箱内温控。

Aiming at the shortage of refrigerated container monitoring system, this paper presents an intelligent monitoring system and method for cold box temperature. Distributed detection on the inside temperature environment using ZigBee wireless sensor network, a cold box system is made by ZigBee network, controller, terminal equipment connected with CAN bus. The hierarchical information fusion and consistency checking algorithm are used to calculate temperature data and fuzzy PID algorithm is adopted for temperature controller. This system can remotely monitor, trace and schedule the refrigerating box, but also can reliably acquire and control the box temperature.
