Abstract
Description
Technical Field
[0001] The utility model relates to the field of intelligent water meter calibration, in particular to a new type of intelligent water meter reading input device. Background Technique
[0002] During the production process of intelligent water meters, after the whole meter is assembled, the mechanical reading needs to be set into the electronic module to achieve the current mechanical and electrical consistency. Then, it is taken to run water, and after running a certain amount of water, it is read again to verify the mechanical and electrical consistency. The traditional setting method is to manually read the mechanical reading and then manually set the electronic module, which is relatively cumbersome and there are situations of reading errors or setting errors.
[0003] In this regard, the applicant applied for a utility model patent with the publication number of CN215182046U, which discloses an intelligent water meter reading input device. It collects the water meter disk image through a camera, then calculates the water meter disk reading through the processor in the computer, and finally inputs the reading into the electronic module through the infrared head, which can reduce the working intensity and improve the working efficiency. However, this device can only be used for intelligent water meters of the same model. Therefore, different models of intelligent water meters need to be equipped with different reading input devices and matched with different algorithms, resulting in higher costs and more cumbersome pre-setting.

For example, it can be a fixed connection, a detachable connection, or an integral body; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.
[0034] The following further describes the present utility model in conjunction with the accompanying drawings and specific embodiments.
[0035] Please refer to Figures 1 to 3 As shown, a new type of intelligent water meter reading input device includes a base 1. A column 2 and a placement table 3 are fixedly arranged on the base 1. A lamp holder 4 is arranged in the middle of the column 2, and a cross bar 5 is arranged at the top. Among them:
[0036] As Figure 1 , the lamp holder 4 is in a "U" shape, and its two sides extend above the two sides of the placement table 3 and are both provided with lighting lamps 6. The lighting lamps 6 are inclined towards the center of the placement table 3 to obtain a better lighting effect; further, the lighting lamps 6 are strip-shaped, and their length is greater than that of the placement table 3, so as to ensure that the lighting range covers the water meter dial.
[0037] As Figure 1 , two sliding brackets 7 and a vertical rod 11 are fixed on the cross bar 5 by screws, and both the sliding brackets 7 and the vertical rod 11 can slide on the cross bar 5. A first camera 9 is arranged on one of the sliding brackets 7, and a rotating bracket 8 is arranged on the other sliding bracket 7. A second camera 10 is arranged on the rotating bracket 8; further, sliding grooves are arranged on the sliding brackets 7, and both the first camera 9 and the rotating bracket 8 are fixed on the sliding grooves by screws, so as to realize the height adjustment of the camera to adapt to different models of water meters and ensure that the camera's viewing range can cover the dial.
[0038] Preferably, the first camera 9 is located directly above the placement table 3, and the second camera 10 is located obliquely above the placement table 3 and is obliquely arranged, so as to take pictures from different angles, effectively improve the accuracy, and realize the acquisition of the pointer positions of different models of water meters; at the same time, due to the existence of the dual cameras, the readings of the digit wheel window can be read synchronously, thus completing the new generation of reading requirements.
[0039] As Figure 1 , a positioning block 14 is arranged on the placement table 3, which can fix the position of the water meter on the placement table 3, thereby ensuring that it is within the shooting range and the angles are relatively unified, reducing the calculation burden.
[0040] It is worth mentioning that, as Figure 2The rotating bracket 8 is provided with a fixing hole 81 and an arc groove 82, wherein the fixing hole 81 is located at the center of the arc groove 82, and the second camera 10 is fixed on one side of the arc groove 82; two screws pass through the fixing hole 81 and the arc groove 82 respectively to fix the rotating bracket 8 on the sliding bracket 7; when the tilt angle of the second camera 10 needs to be adjusted, the screws are loosened to allow the rotating bracket 8 to rotate with the axis of the fixing hole 81 as the rotation center, and the screws are tightened when the appropriate angle is adjusted.
[0041] It is understandable that if Figure 1 A rotating block 12 is provided at the bottom of the vertical rod 11, and the rotating block 12 is connected to the instruction issuing module 13 through a connecting rod; the rotating block 12 can rotate on the vertical rod 11, so as to adjust the position of the instruction issuing module 13 to adapt to different types of water meters, ensuring that the instruction issuing module 13 and the communication module of the water meter are within the communication range.
[0042] It should be noted that in order to achieve reading acquisition and writing, such as Figure 3 , the device also includes a data acquisition module, a port communication module, a data decoding module, a decoded data storage module and a data calling module. The specific process is as follows:
[0043] First, the first camera 9 and the second camera 10 take pictures of the smart water meter on the placement table 3. The data acquisition module is connected to the first camera 9 and the second camera 10 and sends the images obtained by the two to the data decoding module through the port communication module. Then, the data decoding module selects the corresponding decoding scheme according to the pointer position distribution and recognizes the word wheel window reading. Thus, the image is converted into reading data and stored in the decoding data storage module. Then, the data calling module calls the reading data in the decoding data storage module and sets it in the water meter electronic module using the instruction issuing module 13 to realize the reading of the smart water meter.
[0044] Furthermore, considering that the readings of the smart water meter are networked, the device also includes a detection data storage module, which stores the reading data in the decoding data storage module to the cloud storage module to complete the backup and facilitate subsequent monitoring.
[0045] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any minor modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
