摘要
为顺应当今楼宇自动化发展趋势,提高室内气体检测有效性,设计了一种基于CAN总线和电化学传感器的家庭或工业环境中的CO实时在线监测和远端控制系统,该系统采用电化学传感器完成气体采集,以低功耗单片机MSP430F5438为数字信号处理平台,并设置了CAN总线的接口。同传统的可燃性气体监测仪器相比,该系统具备功耗低、监测数据准确、实时性强、数据存储和远程传输等优点。经过对实验装置的测试,本系统准确检测气体浓度,达到预定的指标要求。
This thesis introduces a real-time detecting and far-control system for CO built on the CANbus and electrochemical sensor, which adapts the electrochemical sensor and develops on the digital signal processing platform of low-power MCU MSP430F5438A. The hardware part consists mainly of electrochemical sensors and signal conditioning modules,LCD display module,CANbus communication module, the micro-controller module and so on. Compared with the traditional combustible gas detection system, it is qualified with lower power loss, high accuracy, data reservation and transmission.
