Automatic detecting system for opening amount of civil air defense door and method thereof

Abstract

An automatic detecting system for an opening amount of a civil air defense door comprises the components of an optical path layout module which is used for acquiring a video image of a door leaf and aframe of the civil air defense door; a data acquisition module which is used for receiving a video image that is acquired by the optical path layout module; an image data server which is used for storing real-time video image information of the door leaf and the frame of the civil air defense door; an intelligent analyzing module which converts the information of the real-time video image of thedoor leaf and the frame of the civil air defense door stored in the image data server, performs analytical calculation, determines an angle opening amount abnormity which are formed by the door leaf and the frame of the civil air defense door in the pixel coordinate, and converts the angle opening amount abnormity to a true opening amount abnormity in a physical coordinate; a display terminal which is used for displaying the determined opening amount abnormity of the civil air defense door; and an electrical master control box which is electrically connected with an optical path layout module,the data acquisition module, the image data server, the intelligent analyzing module and the display terminal. The automatic detecting system realizes checking for the opening amount change conditionof the civil air defense door according to the requirement at any time.

Description

technical field [0001] The invention belongs to the technical field of civil air defense doors, in particular to an automatic detection system for the state of civil air defense doors. Background technique [0002] The civil air defense door is exactly the door of the entrance and exit of the people's protection project, which is used to protect the refugee crowd, block poisonous gas, and blast the door used for killing and wounding. The opening and closing state of the civil air defense door is different in different periods. It is always open in peacetime and closed in wartime or exercise period. The civil air defense project in the subway project is in a special state. In the normal state, the civil air defense door is opened to facilitate the high-frequency passage of subway vehicles and improve the city's traffic operation capacity; For a confined space, to protect the safety of people's lives and property. Generally speaking, civil air defense doors can be divided in...

AI Technical Summary

Problems solved by technology

[0004] For the detection of the switching value of the civil air defense door, at present, it mainly relies on the inspectors to find problems and report them during the routine inspection at intervals. There are many deficiencies in efficiency, accuracy and timeliness of switch state maintenance
