Civil air defense door position state detection system and method based on support bar identifier

Abstract

The invention relates to a civil air defense door position state detection system and method based on a support bar identifier. The system comprises a light path layout module which is provided with multiple cameras and is used for shooting support bar identifiers coated with the color paint having the same spectral characteristics as the cameras, a data acquisition module used for receiving videoimages acquired by the light path layout module, an image data server used for storing the original and real-time video image information of the support bar identifiers, an intelligent analysis module used for converting the original and real-time video image information of the support bar identifiers stored in the image data server into the pixel coordinate calibration information, carrying outanalysis and comparison, determining the abnormal position state condition of a civil air defense door in a pixel coordinate and converting the abnormal position state condition into the abnormal real-position state condition in a physical coordinate, and a display terminal used for displaying the determined abnormal position state condition of the civil air defense door. The system is advantagedin that an electrical main control cabinet is utilized to control a device work state, the state of the civil air defense door can be displayed in real time, and thereby operators are facilitated to master the state of the civil air defense door and are convenient to carry out maintenance.

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. It is left open for a long time in peacetime. The position of the civil air defense door exceeds the limit, which means that the civil air defense door is not opened properly, exceeding the limit of the position where the civil air defense door should be located. When the civil air defense door moves beyond the limit, in some cases, it will cause serious safety accidents. For example, when the protective airtight partition door of the subway section installed next to the track exceeds the limit, it will be at the upper position of the track, w...

AI Technical Summary

Problems solved by technology

The detection of the falling of the support rod and the over-limit and cross-border detection of the civil air defense door mainly depends on the routine inspection of the inspection personnel. This method cannot detect problems in real time and give early warning and alarm
