A system and method for detecting the position and state of civil air defense doors based on support rod identification

Abstract

A system and method for detecting the position and state of a civil air defense door based on a support rod mark, the system includes: an optical path layout module, which is provided with a plurality of cameras, and photographs a support rod mark coated with a color paint having the same spectral characteristics as the camera; The data acquisition module receives the video image obtained by the optical path layout module; the image data server stores the original and real-time video image information of the support rod identification; the intelligent analysis module converts the original and real-time video image information of the support rod identification stored in the image data server Calibrate the information for the pixel coordinates, analyze and compare, determine the abnormal situation of the position and state of the civil air defense door in the pixel coordinates, and convert it into the abnormal situation of the real position and state in the physical coordinates; display the abnormal situation of the determined position and state of the civil air defense door Display; use the control of the working status of the equipment by the electrical main control box to display the status of the civil air defense door in real time, so that the operation and maintenance personnel can understand the status of the civil air defense door and repair it.

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
