Description

Technical Field

[0001] The utility model relates to the technical field of video recognition devices, in particular to a device for recognizing the state of an inspection door based on video. Background Art

[0002] In the fields of industrial production, power facilities, public facilities, etc., inspection doors are usually installed on the corresponding equipment. Such inspection doors are designed to facilitate the opening of the inspection doors for corresponding maintenance operations when needed. However, in actual operations, when the staff opens the inspection door to complete the maintenance operation, they may unconsciously leave the inspection door open. If the inspection door is not closed, dust and other substances may enter, affecting the normal operation of the equipment. At this time, status monitoring of the equipment inspection door is of great significance to ensure the safe operation of the equipment.

[0003] Traditional inspection door status monitoring methods mainly rely on manual inspections and physical equipment such as limit switches. The manual inspection method is difficult and requires manual inspections on site, which is a complicated process. When using physical equipment such as limit switches for operation, it is difficult to correctly judge whether the inspection door is closed due to power outages and other situations. As a result, the above method has the disadvantages of low efficiency, high false alarm rate, and inability to monitor in real time.

[0004] At present, in order to improve the detection efficiency and reduce the manual workload, the device for video recognition of the state of the maintenance door is usually used for detection operation. This type of video recognition device for the state of the maintenance door usually uses a camera to capture the state of the maintenance door, and then transmits the picture to the control host for judgment and processing to identify the state of the maintenance door. When the maintenance door is not closed, an alarm can be issued to achieve the effect of reducing the workload. However, when installing and using this type of video recognition device for the state of the maintenance door, since the maintenance door needs to be opened outward, at this time, the device for video recognition of the state of the maintenance door is usually installed on the side of the maintenance door of the equipment. Since the camera is generally fixed with a bracket, the length of the bracket is determined at the factory, and the extension length of the bracket cannot be adjusted. If the extension length of the bracket is too long or too short, it will cause the camera and the side position of the maintenance door to be misaligned, further causing the camera to capture the closed state of the maintenance door. Errors are prone to occur, affecting the recognition effect and causing inconvenience to the user. In view of this, we propose a device for video recognition of the state of the maintenance door.
