[0002] A smart water meter consists of a mechanical meter and an electronic backpack. The mechanical meter is the core of the metering process, while the electronic backpack collects the metering data and performs digital processing, storage, and transmission. Therefore, the mechanical meter is the data source for the electronic backpack, and the electronic backpack is a functional extension of the mechanical meter. The combination of the two realizes the upgrade from traditional mechanical water meters to smart water meters, and neither can be dispensed with.

[0003] In existing technologies, the binding between the smart water meter and the electronic backpack during the production stage is basically achieved through manual scanning, resulting in low binding efficiency.

[0022] To address the problems in existing technologies, this embodiment provides a method for binding a smart water meter to an electronic backpack, which improves the binding efficiency. In specific application, firstly, an image of the smart water meter is acquired. Based on the image, the device serial number of the electronic backpack, the meter number, and the water meter reading are identified. Then, based on work order information, a configuration file is obtained. Parameters in the configuration file are compared based on the device serial number and the meter number. After successful parameter comparison, the device serial number and water meter number are bound together, and the water meter reading is recorded by a host computer. Compared to the manual scanning binding method in existing technologies, this embodiment uses image recognition technology to achieve binding, avoiding manual intervention and improving binding efficiency.

[0023] The binding method between the device and the electronic backpack in this embodiment can be applied to a terminal, which is a host computer product such as a computer. Specifically, for example... Figure 1 As shown in the figure, the binding of the device and the electronic backpack in this embodiment specifically includes the following steps: Step S100: Obtain the image of the smart water meter, and identify the device serial number, meter number, and water meter base number of the electronic backpack based on the image of the smart water meter.

[0024] This embodiment utilizes image recognition technology to bind the smart water meter to the electronic backpack. To achieve this, images of both the smart water meter and the electronic backpack need to be acquired. Relevant information is then obtained through image recognition. Specifically, this embodiment first acquires an image of the smart water meter, which includes both the meter image and the electronic backpack image. Next, the smart water meter image is recognized and processed to obtain the electronic backpack's serial number, the meter number, and the water meter reading.

[0025] In practical applications, the binding of the smart water meter and the electronic backpack is achieved by linking the electronic backpack's device serial number with the smart water meter's serial number. Therefore, identifying the electronic backpack's device serial number and the smart water meter's serial number is crucial. This embodiment utilizes a preset image acquisition device, which includes a camera and a light source. The camera is used to acquire images, and the light source provides supplementary illumination to improve image quality. During image acquisition, this embodiment first adjusts the shooting angle of the image acquisition device so that the camera faces both the smart water meter and the electronic backpack. Then, the brightness of the light source is adjusted. In this embodiment, the adjustable range of the light source is 260 LUX to 760 LUX. This embodiment allows selecting the most suitable light source brightness before image acquisition. Then, based on the adjusted shooting angle and light source brightness, images of the smart water meter and the electronic backpack are acquired to obtain the smart water meter image.

[0026] In one implementation, the smart water meter and electronic backpack are transported to the image acquisition station via an automated transport device. The image acquisition device then captures images of both the smart water meter and the electronic backpack, and binds them together. To improve image acquisition efficiency, the smart water meter and electronic backpack can enter the image acquisition station simultaneously for image acquisition, allowing both to be captured in a single image. Furthermore, after image acquisition of the smart water meter and electronic backpack is complete, they are transported to the next process via the automated transport device, and the next smart water meter and electronic backpack automatically enter the image acquisition station for image acquisition, thus achieving fully automated image acquisition with a continuous process, effectively improving efficiency. In another implementation, to further improve image acquisition efficiency, this embodiment can simultaneously capture images of multiple smart water meters and electronic backpacks to achieve simultaneous binding of multiple devices.

[0027] Furthermore, after acquiring the smart water meter image, this embodiment further optimizes the image by removing noise areas unrelated to the meter and electronic backpack—that is, areas excluding the meter and backpack. Next, this embodiment can increase the resolution of the smart water meter image; preferably, the resolution is adjusted to greater than 800*600. Furthermore, this embodiment can adjust the image clarity to improve image recognition in subsequent steps and obtain relevant information.

[0028] Specifically, after acquiring a smart water meter image, the image is uploaded to a host computer (such as a computer) for recognition. In this embodiment, when recognizing the smart water meter image, the serial number area of ​​the electronic backpack and the meter number area can first be located in the smart water meter image based on optical character recognition technology. Next, the device serial number in the serial number area and the meter number in the meter number area are recognized. Then, based on the smart water meter image, the dial area is located, and the pointer position in the dial area is identified to determine the initial water meter reading. In this embodiment, the initial water meter reading is the initial data of the smart water meter before it is officially used. In practical implementation, the recognition effect of the pointer position may be affected by factors such as light or dial contamination. In this embodiment, after locating the dial area, a shape matching method is first used to match the strip-shaped objects in the dial area. After identifying the strip-shaped objects, the orientation of the strip-shaped objects is determined. The water meter reading is determined based on the orientation of the strip-shaped objects. For example, if the strip-shaped objects are identified as being diagonally upward, the reading for diagonally upward orientation can be determined, thereby obtaining the water meter reading.

[0029] In another implementation, the image acquisition method for smart water meters in this embodiment can be set according to the actual situation of the production process. For example, images of batches of smart meters and electronic backpacks can be acquired sequentially using an image acquisition device, and then the acquired images can be saved. When the smart meters and electronic backpacks are transported to the current workstation, the previously acquired images can be directly retrieved for image recognition. Furthermore, when identifying the IMEI of the electronic backpack and the meter number of the smart meter, this embodiment can add special character recognition to the optical character recognition technology, such as recognizing combinations of numbers and English letters, or recognizing specific letters. This allows for faster location of the serial number area of ​​the electronic backpack and the meter number area of ​​the smart meter, improving recognition efficiency. Furthermore, to further improve recognition efficiency, this embodiment can directly determine the estimated length of the device serial number (IMEI) and the watch number when recognizing the electronic backpack's IMEI and the watch number. Then, a recognition standard is set based on the estimated length. Based on this recognition standard, the regions in the acquired image that meet the recognition standard are quickly located. This allows for faster location of the electronic backpack's serial number region and the watch number region.

[0030] In other implementations, this embodiment can also construct an image recognition model to automatically recognize smart water meter images, automatically locate the serial number area of ​​the electronic backpack and the meter number area, and automatically output the device serial number in the serial number area and the meter number in the meter number area. Similarly, the image recognition model can also automatically locate the dial area on the meter and automatically output the water meter reading. Furthermore, if valid information cannot be identified from the smart water meter image, such as the device serial number of the electronic backpack, the meter number, or the water meter reading, an error message can be output, prompting manual verification. Valid information is then obtained through manual verification and input into the host computer.

[0031] Step S200: Based on the work order information, obtain the configuration file, and compare the parameters of the configuration file based on the device serial number and the table number.

[0032] After completing the acquisition and recognition of smart water meter images, this embodiment needs to determine the identified device serial number and meter number, and verify the smart meter and electronic backpack to identify qualified smart meters and electronic backpacks. Specifically, this embodiment first obtains work order information. In this embodiment, the work order information can be stored in a preset location in the host computer. Based on the current batch information, the corresponding work order information can be read. The work order information records all information (such as device serial number or label), process status, and data of the currently annotated smart meter or electronic backpack, forming a configuration file. After obtaining the configuration file, this embodiment compares the device serial number and the meter number with the configuration file item by item to determine whether the device serial number and the meter number are in the configuration file. If the device serial number and the meter number are in the configuration file, the target parameter is obtained from the configuration file. This target parameter is a pre-stored parameter corresponding to the device serial number or meter number. For example, if the target parameter of the current smart meter needs to be obtained, it is obtained based on the meter number of the current smart meter; if the target parameter of the current electronic backpack needs to be obtained, it is obtained based on the device serial number of the current electronic backpack. Next, the target parameters are compared with the real-time parameters of the smart water meter and / or the electronic backpack. These real-time parameters can be obtained from the currently acquired smart water meter image. Since the smart water meter image includes images of the electronic backpack and the smart water meter, it can reflect other parameters, such as voltage range (e.g., 3.3V ± 5%). Reading these parameters yields the real-time parameters. Alternatively, real-time parameters can be obtained by reading the smart water meter or electronic backpack using serial port commands, such as the signal quality of the current electronic backpack. After obtaining these real-time parameters, this embodiment compares them item by item with the corresponding target parameters in the configuration file. If the target parameters match the real-time parameters, the parameter comparison is successful. This indicates that the current smart water meter or electronic backpack matches the parameters in the pre-stored configuration file, and the smart water meter and electronic backpack are qualified. If the device serial number and / or the meter number are not in the configuration file, or if the target parameters do not match the real-time parameters, a parameter comparison error message is output.

[0033] Step S300: After the parameter comparison is successful, the device serial number is bound to the water meter number, and the water meter reading is recorded by the host computer.

[0034] After successful parameter comparison, this embodiment can bind a qualified water meter to a qualified electronic backpack. Binding involves associating the electronic backpack's serial number with the meter's serial number. After binding, this embodiment can save the obtained water meter readings to a preset location on the host computer, so that the smart water meter can be used for counting after it is officially put into use. During actual use, the electronic backpack can be fixed to the water meter. The electronic backpack uses non-magnetic induction technology to obtain signals from inside the meter, facilitating the reading. After reading the reading, the electronic backpack can upload the reading to the host computer for storage via Bluetooth.

[0035] Furthermore, this embodiment also generates a unique tag for the bound machine and electronic backpack. This unique tag can be a qualified tag code, which is used to reflect that the machine and electronic backpack are qualified and have been bound. Then, the unique tag is associated with the work order information and stored in the host computer system.

[0036] In one implementation, after binding the smart water meter to the electronic backpack, this embodiment also performs an air-blowing test on the smart water meter to check its airtightness and the electronic backpack's data reading function. Specifically, this embodiment uses an electromechanical synchronization device to perform the air-blowing test on the smart water meter and read its metering reading. This air-blowing test simulates water flow through the inside of the smart water meter, used to check both its airtightness and the unobstructed flow of its internal passages. During the air-blowing test, the meter's dial pointer also generates data, which can then be recorded. In this embodiment, the metering reading is reflected by the position indicated on the dial of the smart water meter; therefore, the determination of the metering reading can also be achieved by recognizing the smart water meter image. Furthermore, the electronic backpack also reads the mechanical motion signal of the dial pointer (i.e., the motion signal of the pointer rotating) through a sensor to obtain the test reading, and sends this test reading to the host computer. Next, this embodiment compares the metered reading with the test reading. If the device serial number and / or if the metered reading matches the test reading, the data reading function of the electronic backpack is deemed qualified. Of course, this embodiment can also automatically generate an anomaly report for abnormal situations and transmit the anomaly report to the host computer's MES (Manufacturing Execution System). The MES system records the entire process of the device and the electronic backpack, facilitating information traceability.

[0037] Furthermore, in other implementations, this embodiment can further calibrate the measurement progress. The meter is a measuring instrument; even if it's bound to the electronic backpack, it needs to be calibrated individually or collaboratively to avoid the problem of the electronic backpack reading accurately while the meter itself is inaccurate. Therefore, this embodiment connects the bound meter to a calibration device, then introduces a standard volume of water, compares the measurement reading corresponding to the meter's dial pointer position with the standard value of the calibration device, and calculates the error. If the error exceeds the acceptable range, it indicates that the meter's measurement function is inaccurate, thus requiring adjustment of the meter's internal structure (such as adjusting the impeller clearance and damper) until the error is acceptable. In another implementation, this embodiment can also perform a waterproof test on the electronic backpack or meter. For example, according to the protection level standard, the electronic backpack or meter is placed in a waterproof test chamber to simulate immersion and spraying environments. After the test, the electronic backpack is disassembled to check for water ingress (such as circuit boards and batteries) and the internal mechanical parts of the meter are checked for corrosion. It can also simulate collisions and pipeline vibrations during transportation and installation. The machine or electronic backpack is fixed on a vibration test bench and tested at a specified frequency (e.g., 10-500Hz) and amplitude. After the test, check whether the impeller of the machine is stuck, and check whether the electronic backpack sensor is offset or whether the wiring is loose.

[0038] In summary, this embodiment first acquires an image of the smart water meter, and then identifies the device serial number, meter number, and water meter reading on the electronic backpack based on the image. Next, based on the work order information, a configuration file is obtained, and parameters are compared between the configuration file and the device serial number and the meter number. Following successful parameter comparison, the device serial number and water meter number are bound together, and the water meter reading is recorded by the host computer. This embodiment utilizes image recognition technology to achieve the binding process between the smart meter and the electronic backpack. Compared to the traditional manual QR code binding method, this invention improves the efficiency of the entire binding process. Furthermore, this embodiment ensures the stability and metering accuracy of both the smart meter and the electronic backpack through a series of tests.

A successful comparison unit is used to determine that the parameter comparison is successful if the target parameter is consistent with the real-time parameter. The prompting unit is used to output a parameter comparison error prompt message if the device serial number and / or the table number are not in the configuration file, or if the target parameter is inconsistent with the real-time parameter.

[0044] In one implementation, the system further includes: The air blowing test unit is used to perform an air blowing test on the meter using an electromechanical synchronization device and to read the meter's measurement reading.
