The Research And Realization Of Intelligent Terminal Of Coal Mine Monitoring Workstation

Intelligent terminal is a in-out equipment. The intelligent terminal faced on coal mine safety inspection and monitoring workstation puts forward some special requirements such as the size of terminals, input mode, communication mode, graphics display capability and so on due to the particularity of the working environment. Through analyzing and studying the existing terminal and the specific situation of the work, in view of the shortcoming of larger size, transfer and carry inconvenient, as well as the single input mode and communication mode of existing terminal, put forward a kind of structure design and implementation method of intelligent terminal of miniature, multi-input mode (standard keyboard, IR , touch screen), multi-communication mode(RS232, 485, Ethernet), having independent character library module and graphics function devoted to industrial control faced on coal mine safety inspection and monitoring. Provide a good interface and means for the man-machine interaction in exceptional circumstances.Complete the hardware circuit and software design and implementation of intelligent terminal. Make the corresponding experiment and debugging of the hardware and software of the intelligent terminal, realize the running well of intelligent terminal, complete the design of the Chinese character library module, realize the GB two-level and user-defined character library, analyze and improve existing graphics function, complete the graphics function faced on the industrial control.The analysis of the test results show that, the new type intelligent terminal can make data input, data processing, data display and data communications real-time accurately, reach the basic aim of the design. Provide solid foundation for further mend and design. Intelligent terminal can be used as an independent in-out devices and also can be used as in-out module of coal mine safety inspection and monitoring workstations, and further perfects the in-out function of new type coal mine safety inspection and monitoring workstation.
