[0002] For a long time, safety exit management has been troubled by the contradiction between public security management and fire protection management. From the perspective of security prevention, the stronger the exit lock, the better. From the perspective of accident escape, the smoother the safety passage, the more effective. Locking the safety door is a taboo for escape in an accident; according to statistics, most of the fire accidents that caused more casualties were caused by the locking of the safety exit or the poor evacuation passage; therefore, the control of the safety exit The problem has been widely concerned by firefighting technicians and managers of densely populated places, and the research on safety exit management has never stopped

[0003] In recent years, domestic and foreign countries have successively developed some safety exit control door locks. Although these products have solved the reliability of door opening, they have relatively large defects in the locking function of the door, so they are not used by managers in densely populated places.
