Design And Implementation Of Drive Software Of Track Monitor And Control Technology Based On CAN In Mine Transport System

The rapid development of Fieldbus technology,Embedded technology and electronic technology provide an opportunity for the leapfrog development of mine production automatization in China. Automantic control system based on Fieldbus system not only has low cost and strong monitoring capability, the field device of system also has high intelligent degree. So the research based on Fieldbus mine monitoring system has very realistic significance.Mine transport monitor is an important component of mine monitoring system. This case concentrated on the research of intelligent mine track monitor&controlmodules based on CANbus, improved two kind of important field equipment--axle counter and switcher through embedded technology, set up an independent track monitoring system and realized intelligent control and data acquisition of related devices in mine track transport.The thesis researched the function and demand of axle counter and switcher. To meet their function and demand, the thesis designed axle counter signal acquisition driver software and switcher safe driver software.According to characters of whole system and modules, the thesis set down the communication protocol to application layer of two intelligent modules.To meet rough environment of coal mine, the thesis designed a set of suitable software anti-jamming methods include watch dog and the redundancy instruction and repetitious read number to solve safety and reliability problems in the system.Finally, to meet the needs of practical use, the thesis established software and hardware simulation test platforms of two modules, test and debugged the system functions comprehensively. After debugging and improving, the axle counter acquisition module and the switcher control module achieved the design requirements in lab circumstance.
