Description

Technical Field

[0001] This utility model relates to the field of power system equipment technology, specifically a device for ensuring the imaging quality of power meter images under random lighting conditions. Background Technology

[0002] Substations, hydropower stations, and other industrial sites are equipped with numerous pressure gauges, both pointer and character types. These instruments are installed amidst complex electrical equipment. Using conventional cameras for inspection presents wiring difficulties. Manual inspection to read instrument readings is typically inefficient. Invention publication number 202322772047.7 proposes a wireless image acquisition device for anti-reflective industrial instruments, employing a movable light-shielding cover to address the issue of ambient light reflection entering the lens. However, real-world scenarios involve numerous random ambient light sources. When the direction of the ambient light is the same as the camera's shooting direction, reflections from the ambient light on the glass casing of the power meter can cause contrast distortion in key areas of the dial image. When the ambient light is on the back or sides of the meter, backlighting and overexposure occur. Conventional methods use light-shielding plates for fixed-point blocking, but due to the randomness of ambient light, such as backlighting and direct sunlight, random ambient light interference can reduce meter reading recognition and accuracy. Therefore, this invention proposes a device to ensure image quality during power meter image capture under random lighting conditions. Utility Model Content

[0003] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0004] Therefore, the technical solution adopted by this utility model is as follows:

[0005] A device for ensuring the imaging quality of power meter images under random lighting conditions includes a dedicated camera for meter identification. A clamp fixing buckle is snapped into the inner side of the dedicated camera for meter identification. A metal fastening clamp is snapped into the other side of the clamp fixing buckle. A random ambient light adapting shell is fitted into the inner ring of the metal fastening clamp. A light shield is fitted on the top of the random ambient light adapting shell, and an observation hole is opened on the side of the top of the random ambient light adapting shell.

[0006] Preferably, the top of the random ambient light adaptable housing is also provided with an artificial observation hole, and the light shield is used to cover the artificial observation hole.

[0007] Preferably, the light-shielding cover is provided with an elastic buckle at the connection between it and the random ambient light adaptable shell, and the light-shielding cover can be rotated to open and close the manual observation hole.

[0008] Preferably, the observation hole of the device is used to insert the recognition head of the meter recognition camera.

[0009] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0010] In this invention, the use of a random ambient light adaptable shell solves the problems of contrast imbalance caused by direct light shining on the glass mirror of the power meter and overexposure of backlit images due to random ambient light. At the same time, the manual observation hole is covered by a light-shielding cover, and an observation hole is set on the side wall to realize a dual observation hole design to solve the problem of manual observation during power meter inspection. The open lower edge design, which is fixed by a metal fastening clamp, can be flexibly adapted to power meters of various sizes and specifications, improving the practicality of the device.

[0019] Example:

[0020] Combination Figure 1-4As shown, this utility model provides a device for ensuring the imaging quality of power meter images under random lighting conditions. It includes a dedicated meter identification camera 110, with a clamp fixing buckle 120 attached to the inner side of the camera 110. A metal fastening clamp 130 is attached to the other side of the clamp fixing buckle 120. A random ambient light adaptation shell 140 is fitted around the inner ring of the metal fastening clamp 130. A light shield 150 is mounted on the top of the random ambient light adaptation shell 140, and an equipment observation hole 160 is opened on the side of the top of the random ambient light adaptation shell 140. A manual observation hole 161 is also opened on the top of the random ambient light adaptation shell 140. The light shield 150 is used to cover the manual observation hole 161. An elastic buckle is provided at the connection between the light shield 150 and the random ambient light adaptation shell 140. The light shield 150 can rotate 360 ​​degrees to open and close the manual observation hole 161. The equipment observation hole 160 is used to insert the identification head of the dedicated meter identification camera 110.
