基于CAN总线和STM32甲烷浓度监测系统设计

Design of monitoring system of methane concentration based on CAN bus and STM32

根据煤矿井下甲烷检测的要求,设计了一种以高可靠CAN总线为传输手段,以低功耗,抗干扰的STM32单片机为处理器的甲烷浓度监测系统。KGS-20型甲烷传感器将采集到的浓度发送到单片机进行处理,当超过报警阀值时系统发出报警信号,同时通过CAN总线接口有效地完成数据的发送和接收。

According to the requirements of the coal mine methane detection, we design a high reliable CAN bus as the means of transport, with a low power consumption, anti-jamming of STM32 MCU methane concentration monitoring system for the processor. KGS- 20 methane sensor, the concentration of collected sent to the single-chip microcomputer for processing, When the alarm value more than the system signal alarm, at the same time through the CAN bus interface effectively complete data sending and receiving.
