Design of simulation software of mine safety monitoring substatio

  • The traditional testing method of coal mine safety monitoring central station monitoring system is to test function and performance of the system by hooking up multiple substation equipments, which not only requires a large amount of hardware cost and complex testing process, but also cannot effectively find potential defects of the system. In view of the above problems, a practical simulation software of coal mine safety monitoring substation was designed. The software adopts data simulation technology, IO multiplexing technology and WebSocket real-time communication technology, and can simulate working mode of substation equipment in real time, interact with the central station monitoring system in action state, and can trigger the abnormal scene dynamically, simulate the concurrent behavior of multiple substations. Meanwhile it can comprehensively test the communication transmission accuracy, timeliness, parallel processing ability and continuous reliability of the central station monitoring system. The test results show that the substation simulation software can take place of substation equipment and simulate vast majority of application scenarios, and can quickly and effectively diagnose flaws of the central station monitoring system from real-time data collection and monitoring, network transmission stability, memory consumption situation, abnormal alarm monitoring, can effectively improve repair cycle of central station monitoring system, which provides guarantee for the stable operation of the central station monitoring system in production environment.
