The Computer Bracket Pressure Monitor System of Fully Mechanized Coalface in Coal Mine Based on CAN Bus

In order to master the relation between the pressure of fully mechanized coalface bracket and the mine coalface moving principle, especially the first coming pressure of the surface of the coal mine influence to bracket, the computer pressure monitor system of fully mechanized coalface bracket in coal mine enterprise based on CAN Bus is developed. The system has dynamic data monitoring function. It could display the setting load of front leg, final resistant pressure and average working resistant pressure of the brackets. It could process data and plot chart in time. When the online pressure comes beyond the maximum value, the software has alarming ability and could create and print a report when it is necessary. It is also important for the managers to make correct decisions. The central host machines support a database. The database stores history curve of working period and all kinds of useful information. It will be advantageous for the safety of workers near the fully mechanized coalface.
