基于CAN总线的室内环境监测系统设计

针对传统室内环境监测系统采集设备简单、数据稳定性与实时性缺乏的缺点,设计一种基于CAN总线的室内环境监测系统。传感器节点采集室内环境数据,通过CAN总线传至监测平台,监测平台对数据进行控制与处理,通过以太网与PC机进行数据传输,实现上位机的实时显示。通过实验验证,监测系统可以稳定可靠运行,为构建更加复杂的分布式监测系统提供了切实可行的参考方案。

THE DESIGN OF INDOOR ENVIRONMENT MONITORING SYSTEM BASED ON CAN BUS

In traditional monitoring system of interior environment, due to simple acquisition equipment, the accuracy and real time performance of collected data is deficient. To overcome the above disadvantage and monitor interior environment, one system based on CAN bus is designed. Sensor nodes are responsibility to acquisition data and transmit that to monitoring platform via CAN bus. The data transmitting between monitoring platform and PC is achieved through Ethernet. The monitoring platform takes change of controlling and processing data which can be real time displayed on upper machine. The experiments show that the monitoring system can keep sta- ble and reliable operation, and further, it provides feasible reference scheme for establishing more sophisticated distributed monitoring system.
