Description

Building access door monitoring system

Technical Field

The invention belongs to the technical field of building safety monitoring, and particularly relates to a building access door monitoring system.

Background

At present, the fire protection design of buildings is more and more emphasized, and a plurality of monitoring systems such as fire alarm, fire door monitoring, electrical fire monitoring and the like are installed in the buildings. For a fire passage, a door sometimes required to be used must be a normally closed fireproof door, and meanwhile, the normally closed fireproof door cannot be locked according to the fire protection requirement, so that although the fire protection regulation is achieved, hidden dangers exist in the aspects of building safety monitoring and burglary prevention. Irrelevant personnel often can pass through the normally closed fireproof door and get in and out, and the anti-theft effect cannot be achieved. Meanwhile, due to the operation of non-professionals, the normally closed fireproof door cannot be kept in a normally closed state, and the normally closed fireproof door cannot play a role in preventing the fire from spreading and the smoke from diffusing when a fire comes. At present, the detection of preventing fire door trouble relies on artifical the detection mostly, and artifical the detection not only work load is big, consume a large amount of manpowers, and efficiency is lower moreover, appear easily omitting. How to coordinate the requirements of fire protection and safety monitoring at the same time becomes a difficult problem at present.
