Abstract: In view of characteristics of low application cost and reliable low-speed communication performance of LIN bus technology, a mine-used control system based on DP/LIN bus was designed. The system is composed of DP/LIN communication host and data collection and output modules based on LIN bus. The DP/LIN communication host is used as main node of LIN bus communication network to realize data conversion between Profibus-DP bus and LIN bus. The data collection and output modules based on LIN bus are used as slave nodes of LIN bus communication network to realize collection of monitored data and output of control signal. Test and actual application results show that the system can reduce production cost of coal mine and improve feasibility of data collection and control.
