Description

Technical Field

[0001] This invention relates to the field of water meter technology, and in particular to a hidden camera visual recognition smart valve-controlled water meter. Background Technology

[0002] Traditional water meters typically feature a dial for displaying real-time flow, requiring water companies to periodically send personnel to read the meters and record water consumption. This method is labor-intensive and inefficient. To address this issue, camera-based smart valve-controlled water meters have emerged. These meters integrate a camera into the meter body, controlled by a remote meter reading module. When meter reading is needed, the terminal system sends a command to the water meter via the remote reading module. The camera then captures the dial reading, converts it into a digital signal, and transmits it to the water management unit, achieving remote data collection.

[0003] However, in existing camera-based water meters, the dial remains unchanged, and the camera directly captures images of it. On one hand, the camera directly facing the dial obstructs the view, making it inconvenient for users to check the readings and for meter inspection. Furthermore, if the camera is positioned directly over the dial, the captured reading will not match the actual meter reading, requiring manual conversion to obtain the correct reading. On the other hand, traditional dials are designed for manual viewing and are therefore relatively large. For the camera to capture the entire dial, it must maintain a sufficient distance, resulting in a large overall meter size and requiring significant installation space. Therefore, a concealed camera-based visual recognition smart valve-controlled water meter is proposed. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention proposes a hidden camera-based visual recognition smart valve-controlled water meter.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a hidden camera visual recognition smart valve-controlled water meter, including a water meter body, a control box housing installed on the top of the water meter body, a control box cover installed on the top of the control box housing, and a counting mechanism and a vision component installed inside the control box housing; The counting mechanism includes a mounting base fixed inside the control box housing. A multi-level digital wheel group composed of multiple digital wheels is rotatably mounted on the top of the mounting base. The digital wheels include a first group of character wheels and a second group of character wheels that are staggered. The characters on the first group of character wheels on each digital wheel can be observed through the control box housing. The vision component includes a vision mechanism fixed inside the control box housing that performs visual recognition and capture of the character wheel group two on each digital wheel. The character observed by the control box housing is the same as the character of the corresponding character wheel group two on the corresponding digital wheel that is visually recognized by the vision mechanism.

[0006] Preferably, the mounting base is provided with a cover plate above it, and multiple number wheels are located between the cover plate. The bottom of the cover plate is provided with an integrally formed side plate, which is fixedly connected to the mounting base. The top of the mounting base is provided with multiple windows II distributed at equal intervals, which are located above the number wheel group I of the corresponding number wheel. The side plate is provided with multiple windows I distributed at equal intervals, which are located on one side of the number wheel group II of the corresponding number wheel.

[0007] Preferably, a shaft is installed on the mounting base, the shaft passes through multiple digital wheels and is coaxially arranged with the multiple digital wheels, and a dial is fixedly installed on the top of the cover plate, the dial having rectangular holes adapted to the multiple windows.

[0008] Preferably, the number wheel includes two coaxially arranged wheel 1s, which move synchronously, and the character wheel group 1 and character wheel group 2 are respectively arranged on the two wheel 1s.

[0009] Preferably, the number wheel includes a second wheel, and both the first and second number wheel groups are disposed on the second wheel.

[0010] Preferably, the vision component further includes a mounting box fixed inside the control box housing, and the vision mechanism further includes a circuit board fixedly connected to the bottom inner wall of the mounting box. A smart vision sensor is fixedly mounted on the bottom of the circuit board. A mounting hole is provided on the bottom inner wall of the mounting box, and the smart vision sensor extends through the mounting hole to the outside of the mounting box and faces multiple windows.

[0011] Preferably, the counting mechanism is provided with a non-magnetic / magnetic reluctance sensor that is rotatably mounted, and the circuit board has a slot coaxially arranged with the non-magnetic / magnetic reluctance sensor. Multiple Hall effect sensors are evenly distributed around the center of the slot on the top of the circuit board.

[0012] Preferably, an actuator and a battery are fixedly installed inside the control box housing, and both the actuator and the battery are located below the vision component.

[0013] Preferably, the control box cover includes an upper housing fixedly connected to the control box housing, a protective cover is fixedly installed on the upper housing, an observation window is provided on the protective cover, and a protective cover adapted to the observation window is rotatably installed on the protective cover.

[0014] Compared with the prior art, the beneficial effects of the present invention are: Compared to traditional manual meter reading, this invention is more efficient and less labor-intensive in reading data, significantly reducing meter reading costs and manpower. Based on the traditional smart water meter's pulse-based meter reading method, it combines a hidden camera structure design to achieve dual meter reading methods, avoiding the problem of meter reading data errors. In addition, it has excellent anti-vandalism and anti-interference performance, strong structural protection, and can adapt to complex installation environments.

[0015] This invention abandons the traditional method of installing intelligent vision sensors externally or directly opposite the dial. Instead, it integrates the vision mechanism hidden inside the water meter and places it on the side of the digital wheel. It uses camera technology to collect readings, which not only avoids the physical obstruction of the digital wheel's view by the vision mechanism, allowing users to directly and clearly view the digital wheel, but also improves the overall aesthetics and integration of the water meter. In addition, the readings captured by the intelligent vision sensor are consistent with the actual readings, eliminating the need for conversion and providing a WYSIWYG experience.

[0016] This invention addresses the problem of bulky size in traditional water meters due to the need to maintain a sufficient shooting distance. It achieves full-view capture of the digital wheel at an extremely short distance. This design makes the overall structure of the water meter more compact, significantly reducing the space occupied during installation and facilitating installation in old residential area renovations or narrow meter wells.

[0017] This invention relies on the remote automatic meter reading function of a hidden vision mechanism, which allows water companies to accurately obtain readings without manual on-site visits. This fundamentally solves the problems of high cost, low efficiency, and difficulty in accessing homes for manual meter reading. At the same time, since the intelligent vision sensor does not obstruct the observation window, quality supervision departments or water companies can visually verify the readings without disassembling the water meter when conducting periodic inspections or anomaly reviews, making the operation more convenient.

[0018] This invention hides the vision mechanism inside the water meter, which, compared to external camera devices, effectively avoids recognition failures caused by water vapor condensation, dial fogging, external scratches, or human damage. The enclosed, hidden environment provides better physical protection for the precision electronic components, ensuring long-term stable operation in humid and dusty environments.

[0027] Furthermore, such as Figures 6-8 As shown, staff can directly observe the corresponding characters on each character wheel group 431 on the number wheel 43 through multiple windows 443, while the intelligent vision sensor 533 can observe the corresponding characters on each character wheel group 432 on the number wheel 43 through the corresponding window 442. When observing the same number wheel 43 from the corresponding windows 442 and 443, the characters displayed on the observed character wheel group 432 are the same as the characters displayed on the character wheel group 431.

[0029] Furthermore, the intelligent vision sensor 533 can not only clearly recognize the characters of the digital wheel 43 in low light or even dark environments, but also perform preprocessing such as noise reduction and enhancement on the original photos to optimize image quality and make the captured images clearer.
