Application of CAN Bus in Coal Mine Remote Monitoring System

Aiming at the shortcomings of the traditional mine monitoring system,a CAN bus distributed remote monitoring system based on ARM embedded system for coal mine was proposed.The whole structure of the online monitoring system was given.The hardware components and the software design process of the CAN bus intelligent nodes were introduced in detail.The microcontroller LPC2292 with an ARM7TDMI-S core was adopted as the kernel of the underground coal mine monitoring sub-stations CAN nodes.Remote users accessed the local embedded web server via industrial Ethernet to obtain the information of the mine safety monitoring system.It has realized the online real-time monitoring and early warning of coal mine gas,carbon monoxide and other parameters.The experimental results show that this monitoring system has advantages of small size,low power consumption,stable and reliable operation.
