Abstract: The limitation of the number of monitoring substations in KJF2000N mine safety production integrated monitoring and control system leads to too long check cycle, which does not meet the requirements of coal mine safety monitoring system performance indexes printed and distributed in the notice of Upgrading Technology Plan for Coal Mine Safety Monitoring System by National Coal Mine Safety Bureau, in order to solve the problem, according to the actual application environment of the existing KJF2000N mine safety comprehensive monitoring system, five methods are proposed, which can effectively improve the inspection efficiency of KJF2000N mine safety integrated monitoring system and shorten the system check period, effectively ensure that the long-distance power outage time is no more than 40 s, timely warning and alarming the abnormal information, and fully guarantee the safety of the workers in the underground.
