| According to the needs of medium-sized steel mills, coal mines ironworks and colliery for shunting operation, combined with the actual situation of the plant area, we use GPS positioning technology to develop GPS-based positioning shunting monitoring system, it improve the system structure and function of the general monitoring system shunting,to ensure the ensure the safety of enterprise railway shuntingShunting monitoring system ground subsystem and vehicle subsystems require line static data to finish drawing the initialization interface and search approach. Incorrect data will lead directly shunting safety monitoring system’s interface display and functional errors. Using CAD technology to replace the traditional manual signal design can improve the level of automation design, make the station design standard, and can improve the level of automation, and then contribute to the promotion of shunting monitoring systemAccording to the demand for line static data, combined with computer-aided design specification, paper design processing CAD software to adapt shunting monitoring system, and take Visual C++on Windows platforms eventually completed the program. First, the paper introduces the GPS-based monitoring system is how to complete the improvement of the system structure and function. And then, it present the station data processing needs of the overall function of the CAD software, describing the overall structure, and dividing logical sub-function modules.After that, though the detailed design of the various software modules, including data initialization, station graphics rendering, equipment and devices automatically associated data storage sub-function modules, we can learn how to complete the drawing and editing icons, building wiring topology data to customize the output.Finally, in accordance with the detailed design of the software, complete the realization of various functions. The results show that the CAD software to draw the station view friendly interface, good interactivity, data links quickly and accurately, data generation compatibility, to achieve the desired research goals. |
