Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

It should be understood that such data can be interchanged where appropriate so that the embodiments of the utility model described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and their variations, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0028] This utility model provides an ultrasonic water meter calibration device. Figure 1 This is a schematic diagram of the structure of an ultrasonic water meter calibration device provided in an embodiment of the present invention, with reference to... Figure 1 The ultrasonic water meter calibration device includes a main control module 10, a two-way communication module 20, and a mode control module 30.

[0029] The bidirectional communication module 20 is connected to the main control module 10, the ultrasonic water meter 100, and the host computer 200. The main control module 10 wirelessly connects to the ultrasonic water meter 100 and the host computer 200 through the bidirectional communication module 20 and exchanges information. The mode control module 30 is connected to the main control module 10 and is used to switch the working mode of the main control module 10.

[0030] The main control module 10 can operate in the following modes: ultrasonic water meter calibration mode, ultrasonic water meter inspection mode, factory default mode, and post-maintenance mode. The mode control module 30 can include a DIP switch or a touch button. When the mode control module 30 is a DIP switch, the operating mode of the main control module 10 differs depending on the switch's position. When the mode control module 30 is a touch button, the operating mode of the main control module 10 differs depending on the touch duration. By setting the mode control module 30, the calibration device can switch between modes under different operating conditions, improving its versatility and ease of use.

[0031] Specifically, since the host computer 200 is wirelessly connected to the main control module 10 via the bidirectional communication module 30, and the main control module 10 is also connected to the water flow platform, the host computer 200 transmits control commands to the main control module 10 via the bidirectional communication module 30. After receiving the control commands output by the host computer 200, the main control module 10 controls the water flow rate output by the water flow platform. This water flow rate includes the water's velocity, volume, and flow rate. The ultrasonic water meter 100 measures the water flow rate of the water flow platform and transmits the measurement result to the main control module 10 via the bidirectional communication module 30. The main control module 10 then transmits the measurement result back to the host computer 200 via the bidirectional communication module 30. Further, the host computer 200 compares the set value of the water flow rate of the water flow platform with the actual measurement result of the ultrasonic water meter 100 to obtain a detection error value. When the detection error value is greater than the preset value, the host computer 200 outputs calibration data to the main control module 10. The main control module 10 then transmits the calibration data to the ultrasonic water meter 100 via the bidirectional communication module 30 for calibration. Furthermore, the ultrasonic water meter 100 measures the water flow rate of the water platform again, and transmits the test result to the host computer 200 to compare it with the set value of the water flow rate of the water platform in order to verify the accuracy of the ultrasonic water meter 100 calibration.

[0032] The technical solution of this utility model embodiment includes an ultrasonic water meter calibration device comprising a main control module 10, a two-way communication module 20, and a mode control module 30. The main control module 10 is wirelessly connected to the ultrasonic water meter 100 and a host computer 200 via the two-way communication module 20 for information exchange. This eliminates the need for a wiring harness between the calibration device and the ultrasonic water meter 100, simplifying the connection and operation, and improving the calibration efficiency of the ultrasonic water meter 100. Furthermore, since the mode control module 30 is connected to the main control module 10, the operating mode of the main control module 10 can be switched via the mode control module 30, allowing the calibration device to meet different operating conditions and improving its versatility and ease of use.

[0033] Figure 2This is a schematic diagram of another ultrasonic water meter calibration device provided in an embodiment of the present invention, with reference to... Figure 2 Based on the above implementation, the bidirectional communication module 20 includes a first communication unit 21 and a second communication unit 22. The first communication unit 21 is connected to the main control module 10 and the ultrasonic water meter 100, respectively, and the second communication unit 22 is connected to the main control module 10 and the host computer 200, respectively. By setting the first communication unit 21 and the second communication unit 22, the communication requirements between different functional modules within the calibration device can be met, thereby improving the versatility and adaptability of the calibration device.

[0034] Continue to refer to Figure 2 Optionally, the first communication unit 21 includes an infrared communication circuit 211, and the second communication unit 22 includes a WIFI communication circuit 221. That is, the main control module 10 communicates with the ultrasonic water meter 100 through the infrared communication circuit 211, and communicates with the host computer 200 through the WIFI communication circuit 221.

[0035] The infrared communication circuit 211 operates by using infrared light signals for communication, transmitting data through the transmission and reception of infrared light signals. Exemplarily, the infrared communication circuit 211 may include an infrared light-emitting diode (LED) and an infrared receiving diode. The LED converts electrical signals into infrared light signals, and the receiving diode converts infrared light signals back into electrical signals. This embodiment does not impose specific limitations. In other embodiments, the infrared communication circuit 221 may employ existing circuit structures capable of infrared communication. The WIFI communication circuit 221 operates based on the Wireless Local Area Network (WLAN) standard, using radio waves for communication and transmitting data using the 2.4GHz or 5GHz frequency band. The WIFI communication circuit 221 may employ existing circuit structures capable of WIFI communication. This embodiment does not impose specific limitations. By separately setting the infrared communication circuit 211 and the WIFI communication circuit 221, the technical solution of this utility model embodiment can improve the versatility and adaptability of the calibration device and reduce system costs.

By setting up multiple LED indicator circuits 40, the current operating mode of the main control module 10 can be indicated, making it easier for operators to observe, thereby simplifying operation and facilitating post-maintenance.
