Research And Application Of Coal Mine Underground Power Supply Monitoring System Based On

Coal mine production mechanization and automation is in the continuous improvement, the working area is also expanding the range, so that the underground power supply security has higher requirements. In addition, under the new situation of coal prices fall, how to use the lowest cost, leveraging existing high (low) burst switch built into various brands of integrated protection and communication lines constructed response fast, secure and reliable, can cover all coal mine power monitoring system communication protocol, both staff efficiency, but also to ensure security of supply, economic realities and significant.To further enhance the degree of automation mine, to safety, staff efficiency goals, the paper based on Anhui Science and Technology Project, "high-speed intelligent programmable serial switch (controller) technology" as the background, relying on the Huaibei Mining Group Company Qinan Coal Mine power monitoring system design project for the test platform, to build a coal mine power monitoring system based on PSC (Programmable Serial Controller, Programmable Serial Controller) technology, can cover the field types and variety of communication protocols integrated protection, real-time read Take the switch operating status and operating parameters, control switching division, setpoint adjustment switch, enabling the power supply system of telemetry, remote, remote control, remote adjustment, remote viewing "five remote" feature, and not through the underground ring Access seam mine automation platform. In the hardware configuration of the system, the next bit machine Guangdong Rule Science and Technology Co., Ltd. research and development Rolle Programmable Serial Controller (PSC), to achieve control of field data collection, conversion and site features such as integrated protection devices by supporting Rstep programming software.PC configuration software configuration king chosen to develop the configuration screen, remote real-time monitoring of power supply system, the parameter retrieval, parameter changes, alarm indication and historical data storage and printing. Complete the system’s hardware configuration, software configuration, the communications and program development, and the next crew, and between field devices next crew.After several field tests and downhole test, the system is stable, to achieve the control requirements, to solve the serial bus communication in the field of large-scale applications, the rate is low, long time delay problem, but also compatible with different types of communication protocols site smart devices, reducing investment in hardware and software costs.
