Abstract


In recent years , China 's coal mine accidents occurred frequently , which account for a large proportion of gas explosion accidents , resulting in significant economic losses and casualties due to such incidents occur instantaneously , destroying , therefore , prevent and eliminate accidents the top priority of coal mine production safety . Currently , China's coal mine safety is commonly used sub-station monitoring system , data cable connection is required between every sensor and underground sub-stations , thus affecting the accuracy of the collected data and real-time , certain hazards caused by coal mine production safety . In view of this , we design a PIC18F4580 microcontroller as the core mine methane the catalytic sensor measurement system . The system is integrated CAN bus controller PIC18F4580 microcontroller as the master controller of the system , simplify the system hardware and software design . In terms of hardware design , launched by the United States Microchip 8-bit microcontroller PIC18F4580 core to build hardware circuit module by methane detection bridge circuit , the signal amplification circuit switch output circuit , AD reference voltage circuit and display circuit . On the software side , the modular design and the use of the arithmetic mean filtering method for digital filtering , the completion of the methane sensor measurement system developed . The research innovation lies in hardware using microcontroller PIC18F4580 as sensor control core , and Microchip MCP2551 CAN transceiver connected to the CAN bus, in order to achieve its communication function . The measuring system with sound and light alarm and concentration functions , the introduction of real - time data filtering and concentration signal upload new features to improve the reliability and convenience of the sensor work .
