Description

Technical Field

[0001] This utility model relates to the field of gas meter modification, specifically to an Internet of Things smart eye remote transmission terminal structure that is installed on the base of a mechanical gas meter. Background Technology

[0002] Gas meters are a crucial component of urban gas supply, but traditional mechanical gas meters have numerous drawbacks, such as inaccurate readings, susceptibility to damage, and difficulties in installation and maintenance. These problems not only affect the user experience but also limit the monitoring and statistical capabilities of gas companies, posing significant risks to gas supply. Therefore, the need for gas meter upgrades is urgent.

[0003] Early gas meter upgrades were based on prepaid IC card gas meters, primarily addressing the prepayment issue. However, these meters had low levels of intelligence, remained inconvenient for users, and prevented gas companies from remotely reading meters and monitoring safety status in real time. Currently, the mainstream upgrade direction is IoT-enabled gas meters. However, this process requires removing the old mechanical meters and replacing them with new ones. Some IoT smart eye terminals have emerged on the market. These terminals use built-in cameras to photograph the digits of mechanical gas meters, process images, and perform digital recognition. The meter reading results are then uploaded to a management center via wireless network. Management software controls the "Internet+" gas meter's operation via wireless communication, monitoring terminal data and status changes, and supporting functions such as billing management, data storage, and data analysis. Replacing manual meter reading with this technology not only enables remote image transmission, intelligent data recognition, and archiving, but also provides archived images as strong evidence in case of billing disputes. Therefore, this product effectively improves meter reading efficiency and the reliability of meter reading data. Traditional smart eye remote transmission terminals use cameras that directly photograph the gas meter digits, requiring a long focusing distance and placing demands on the overall height of the terminal's casing. This makes them unsuitable for gas meters installed in confined spaces. Summary of the Invention

[0004] The purpose of this invention is to provide an IoT smart eye remote transmission terminal structure that can be installed on a mechanical gas meter base. The built-in reflective lens can reflect the reading of the digit wheel onto the lens, and the miniature camera only needs to capture the reading of the digit wheel in the lens. This structure shortens the imaging focal length of the camera and also reduces the overall height of the smart eye remote transmission terminal housing, making it suitable for retrofitting mechanical gas meters that are installed in confined spaces. In addition, the lower housing has an adjustable structure that can adjust the left and right position of the camera according to the difference in the camera's imaging image to achieve the optimal position for the captured image.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: An IoT smart eye remote transmission terminal structure, connected to a mounting base via screws, wherein the mounting base is fixed to the gas meter base via clips or screws according to different gas meter types, comprising an upper housing, a lower housing, a camera, a camera bracket, a lens, a housing sealing strip, LED beads, and LED bead fixing caps, characterized in that:

[0006] The lower housing is provided with a limiting post, and the lens is placed in the buckle provided with the limiting post;

[0007] The lens can reflect the readings from the digit wheel on the gas meter base to the lens;

[0008] The angle of incidence between the lens and the dial of the gas meter is equal to the angle of reflection between the lens and the camera.

[0009] The camera takes pictures of the readings on the digit wheel of the gas meter base and is fixed by a buckle on the camera bracket;

[0010] The camera bracket is fixed inside the lower housing with screws;

[0011] The lower shell is equipped with an adjustable structure, which can adjust the left and right positions of the camera according to the differences in the camera's image.

[0012] The lower housing is provided with two LED lamp bead mounting holes. The LED lamp beads are placed in the mounting holes and pressed tightly with LED lamp bead fixing caps.

[0013] The LED beads are used to provide supplemental lighting for camera shooting in low-light conditions;

[0014] The lower housing is provided with a battery compartment for placing batteries;
