摘要: 为了解决KJF2000N矿井安全生产综合监控系统在进行环网改造后受挂接监控分站数量限制,导致巡检周期过长的问题;针对现有KJF2000N矿山安全综合监控系统在矿井环网环境下实际应用的实际,结合环网网络协议与设备的特点,优化软件采集算法,达到缩短系统巡检周期的目的,有效地保证异地断电时间不超过40 s,及时对异常信息进行预警与报警,充分保障井下工作人员生命安全。通过煤矿现场的应用验证,采用软件采集优化的方式,有效地提高了巡检效率,不但满足改造技术方案关于系统巡检周期不超过20 s要求,而且远高于标准要求。Abstract: To solve the problem that the KJF2000N mine safety production integrated monitoring system is limited by the number of connected monitoring substations after the ring network reform, which leads to the long inspection period, the existing KJF2000N mine safety integrated monitoring system has been applied in the mine ring network environment. Combining with the characteristics of ring network protocol and equipment, optimize software acquisition algorithm to shorten the system inspection cycle can effectively ensure that the off-site power cut time does not exceed 40 s, timely warn and alarm abnormal information, fully protect the safety of underground workers. The application in coal mine proves that the efficiency of patrol inspection is effectively improved by software acquisition and optimization, which not only meets the requirements that the patrol inspection period of the system does not exceed 20 s, but also is far higher than the standard requirement.
