The Real-Time Monitor System For The Disc-Shaped Brake

This article introduced the real time monitor system for the disc-shaped brake of lift machine in coal mine, and the system is consist of main system and subsystem.It is detailed to introduced the subsystem with procedure design of machine frame and its working principle, including sensor electric circuit, micro-controller, analog -digital signal converter electric circuit, memory, display, controller reset, communication interface, the alarm device, dependable design for subsystem.The function of subsystem is real time to examination distance between the disc-shaped brake and the column, and display the data at the local place. The system judges distance of the disc-shaped brake with the initial the value if it is within the scope of provision. If not, it sends the signal to the alarm device which will make harsh sound and the bright light. The local indicates that data .By the communicate interface subsystem sends the data to the computer which can be far away form the local. The data will be displayed on the screen with the special programmer. At the same time with the multi-media advantage computer will examine the data and determine whether the alarm will work.This article also introduced the design of software for the main system acted as computer, including the software flow chart corresponds with letter and the communication program.System electric circuit principle chart with the program are results by authors from all of procedures personally and physically on trial. All electric circuits are all tested to be all right for long time, and those measure accurate, data communicate dependable, display normally.The system in this article makes use of the micro-controller to build the subsystem to examine the distant of the disc shaped brake. It can be used by main system in foreign place to inspect the local working states, and also can used for the long range to survey the distant of the disc shaped brake or to help control as another means.
