Full autoamtic control device for evacuating door

Abstract

This invention discloses a automatic control device of dispersal door, it contains electromagnetic lock used for installing in the dispersal door, and electromagnetic lock-switch testing circuit, the output of electromagnetic lock-switch testing circuit and SCM are anastomosis, SCM fits together with incoming end of master controller through communication interface; fire alarm signal links to incoming end of master controller by manual or automatic control circuit; power circuit links to electromagnetic lock by manual or automatic control circuit; yet display circuit links to master controller. It could realize automatic control the electromagnetic lock of dispersal door. When there is not emergency, it makes the electromagnetic lock in blocking state, so as to satisfy the public security demand of public security departments; when there is emergency, it could automatically unlock according to alarm signal, ensure the in time escape of personnel, accord with prescription of fire agent, which safeguard against fatal accident of not open dispersal door when staves taken charge of unlocking failure to arrive the scene, and avoid loss of burnout spreading out.

Description

Technical field: [0001] The invention relates to a device for controlling the switch of an evacuation door, in particular to a fully automatic control device for the evacuation door which can monitor and control the switch state of the evacuation door. Background technique: [0002] The evacuation door is a door installed on the fire escape, and its purpose is to evacuate people in an emergency. For this reason, the fire department requires that the door should be in a normally open (unlocked) state. But the public security department considers from the angle of maintaining social order, and requires that this door should be in a normally closed (locked) state, and then it is opened when a fire breaks out. In order to reconcile the contradiction between the fire department and the public security department, the current evacuation doors basically have the following two structural modes: one is an evacuation door with a mechanical linkage door lock, and the mechanical linkage...

AI Technical Summary

Problems solved by technology

But because the people in the evacuation door can go out at will, it is not convenient for the operation and management of businesses such as shopping malls, hotels, theaters, etc. For this reason, the businessmen lock the mechanical linkage door locks, and the key is held by a special person; for electromagnetic locks, A program controller is also installed, which must be opened with a special program magnetic card

In this way, if an emergency occurs and the special unlocking personnel cannot arrive at the scene in time, there will be casualties caused by the inability to open the evacuation door, causing irreparable losses.
