摘要
传统的煤矿安全监控中心站监控系统测试方法是通过挂接多个分站设备对系统功能及性能进行检测,不仅需要投入大量的硬件设备成本,测试过程繁琐,而且不能有效发现系统潜在的缺陷。针对上述问题,设计了一款实用的煤矿安全监控分站模拟软件,该软件利用数据模拟技术、IO多路复用技术及WebSocket实时通信技术,可以实时模拟分站设备的工作模式,与中心站监控系统进行动态交互,能动态触发异常场景,并能模拟多分站的并发行为,对中心站监控系统的通信传输准确性、时效性、并发处理能力及连续可靠性等进行全方位的检验。测试结果表明,分站模拟软件能代替分站设备模拟绝大部分的实际应用场景,能从实时数据采集监测、网络传输稳定性、内存消耗情况、异常报警监控等方面快速、有效地诊断出中心站监控系统存在的问题,有效提高中心站监控系统的修复周期,为现场稳定运行提供保障。
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.
