Design of CBM Ground Recorder and Development of Monitoring System

In order to realize the automatic real-time monitoring task in the development process of structural coal-bed methane,a low-power ground recorder and a coal-bed methane monitoring system are designed in this paper. The ground recorder uses low-power STM32 L433 RC as the main controller,MAX485 EN as the interface chip,W25 Q64 as the memory chip,and adopts 485 bus transmission and Modbus serial communication protocol. The real-time transmission processing and server storage are realized through the master-slave task conversion. The upper computer is programmed with Kingview software. The designed coal-bed methane mining monitoring system has the characteristics of low coupling,multiple equipment,and high integration,which improves the automation of coal-bed methane mining.Finally,the experimental results show that the designed low-power ground recorder can effectively upload sensor data,complete data communication with multiple instruments,and meet the actual needs.
