Technical Field
[0001] The utility model relates to the technical field of civil air defense doors, in particular to an open and closed state monitoring civil air defense door. Background Art
[0002] Civil defense doors are the doors at the entrances and exits of people's defense projects. They are clearly classified into ordinary single-leaf and double-leaf protective closed doors and closed doors, movable threshold single-leaf and double-leaf protective closed doors and closed doors, and other civil defense equipment. They are activities for the government to mobilize and organize the masses, take anti-air raid, disaster relief measures, implement rescue operations, and prevent and reduce disaster hazards. Civil defense doors are civil defense protection equipment.
[0003] When the existing civil defense door is in use, it is impossible to detect whether the civil defense door system is in a completely closed state. Once the moment of using the civil defense door comes, it is a matter of life and death. Any mistake requires staff to conduct repeated inspections, which affects the efficiency of the use of the civil defense project. Utility Model Content
