It should be understood that those skilled in the art can modify the present invention described herein while still achieving the beneficial effects of the present invention. Therefore, the following description should be understood as being widely known to those skilled in the art and not as a limitation of the present invention.

[0038] For the sake of clarity, not all features of the actual embodiments are described. In the following description, well-known functions and structures are not described in detail because they would clutter the invention with unnecessary detail. It should be recognized that in the development of any actual embodiment, a large number of implementation details must be made to achieve the developer's specific goals, such as changing from one embodiment to another according to the limitations of the relevant system or the relevant business.

[0039] The present invention is described in more detail in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become more apparent from the following description and claims. It should be noted that the drawings are in very simplified form and in non-precise proportions, and are only used to facilitate and clearly assist in illustrating the purpose of the embodiments of the present invention.

[0040] Please refer to Figure 1 , Figure 3 , Figure 4 and Figure 6 As shown, an embodiment of the present invention provides a smart valve monitoring device, including a Hall sensor assembly, a main control box body 1, a main control board 131, and a communication board 132; the main control board 131 and the communication board 132 are both included, and the Hall sensor assembly is arranged on the main control board 131 to sense the change of the magnetic field when the valve rotates;

[0041] The main control board 131 is provided with a microcontroller component for receiving the output signal of the Hall sensor component and sending the output signal to the communication board;

[0042] The communication board 132 also includes a wireless module for transmitting the output signal to a remote server.

[0043] In one embodiment, the smart valve monitoring device is mainly used to collect signals and transmit the signals to the remote server, and then the remote server performs subsequent data analysis. The content of the subsequent data analysis is not within the scope of the present invention.

[0044] In another embodiment, after receiving the output signal of the Hall sensor component, the microcontroller component can also analyze and determine the valve status data such as the rotation direction, number of revolutions and duration of the valve, and then the communication board 132 sends the valve status data to the remote server for subsequent data analysis. The content of the subsequent data analysis is not within the scope of the present invention.

[0045] In this embodiment, the smart valve monitoring device further includes a pipeline vibration sound collector 2. The pipeline vibration sound collector 2 and the main control box body 1 are clamped on a rotatable first bracket 3 and rotate in coordination with the valve head.

[0046] In this embodiment, if Figure 1 As shown, a plurality of second brackets 4 are provided at the upper end of the first bracket 3 and in a direction perpendicular to the length direction of the first bracket 3. In this embodiment, the number of second brackets 4 is schematically shown to be 4. The second brackets 4 can be used to fix the smart valve monitoring device on a valve well (not shown).

[0047] Specifically, the second bracket 4 is in the shape of a long strip, and the middle part of each second bracket 4 is formed by connecting a plurality of cylindrical long strips with screws, and a disc-shaped fixing device 42 is connected to the end of the second bracket 4, which is used to fix the smart valve monitoring device on the valve well. The head ends of the plurality of second brackets 4 are welded together on a circular first sleeve 41. A square first fixing plate 44 is clamped on the upper end of the first sleeve 41, and there are a plurality of first openings 45 above the first fixing plate 44. The first openings 45 are in the shape of a long strip. In this embodiment, the schematic diagram shows that the number of first openings 45 is 4. The first opening 45 can be used to clamp the magnetic pole 43.

[0048] In this embodiment, the first bracket 3 is in the shape of a rectangular strip connected by a plurality of support rods, including a first support rod 31 , a second support rod 32 and a third support rod 33 .

[0049] The first support rod 31 is located at the top of the first bracket 3, and the first sleeve 41 in the middle of the second bracket 4 can just pass through the first support rod 31, and a support cap 301 is clamped at the top of the first support rod 31, and the support cap 301 plays a fixing role, used to prevent the second bracket 4 from sliding upward. A second sleeve 302 is provided on the first support rod 31, and a second fixing plate 303 is provided on one side of the second sleeve 302, and the second fixing plate 303 is used to clamp the main control box body 1.

[0050] Since the width of the second support rod 32 is greater than that of the first support rod 31, the upper end of the second support rod 32 can be inserted into the lower end of the first support rod 31 and fixed with screws. The lower end of the second support rod 32 is threadedly connected to the upper end of the pipeline vibration sound collector 2.

[0051] The upper end of the third support rod 33 is provided with a first flange 331 , and the first flange 331 is fixed to the second flange 25 at the lower end of the pipeline vibration sound collector 1 by screws, and the lower end of the third support rod 33 is connected to the valve port.

[0052] like Figure 3 , Figure 4 , Figure 6 and Figure 8 As shown, the main control box body 1 includes two boards and a battery module 133, wherein one board is a main control board 131. Figure 4 As shown, it is arranged on one side of one end of the main housing 13, and the main control board 131 is provided with the Hall sensor component and the microcontroller component; the other board is a communication board 132, which is arranged on the other side of one end of the main housing 13, as shown Figure 6 As shown, there are a wireless module and a Beidou positioning module on the communication board 132. The main control board 131 and the communication board 132 in the main control box body 1 are connected by wires.

[0053] like Figure 5The wiring diagram of the main control board 131 in one embodiment of the present invention is shown. The main component of the main control board is the U20 chip, which is made in the United States. It performs internal calculations and is mainly responsible for lap counting, voltage alarm, time display, FFT calculation, waveform analysis and other functions. The specific functions are as follows: the battery power enters from CN1 input, passes through diode D1 (to prevent short circuit protection of the battery), and steps down U12 and U13 to obtain 3.3V voltage. U12 supplies power to the main control chip U20, and U13 supplies power to the external sensor. The sensor signal is input to the main control chip U20 through the U6 isolation chip. The main control chip is operated and processed internally to determine whether there is a water leakage signal. If there is a water leakage signal, a 111 control signal is sent to the 4G module and sent out through the serial port CN5. If there is no water leakage signal, it will not be sent, and only a 777 signal will be sent out. The circle counting is through three Hall sensors S1, S2, S3, which are input to the main control chip by INT1, INT2, INT3. Three Hall parts need to be sensed for each circle. The vibration alarm is first triggered by the O1 vibration switch. After the trigger signal is given to the main control U20 MCU, the MCU will detect U5 and the gyroscope to see if there is a tilt. If so, a 999 alarm signal will be sent out.

[0054] like Figure 7 and Figure 8 The wiring diagram of the communication board 132 in one embodiment of the present invention is illustrated. It mainly includes U1 and U3. U1 is a control signal chip and U3 is a GPS signal processing chip. When U1 sends a signal to U3 to receive a GPS signal, U3 turns on the signal processing, receives the GPS signal, and displays the geographic coordinates in real time. The power supply is supplied to U3 and U2 through CN1, respectively, and converted into 3.3V. After the 4G signal is sensed by the antenna, it is directly input into the U1 control processing chip. After the U1 control processing chip is processed by calculation, the internal 4G signal processor is started, and the serial port signal from the main control is sent out through the 4G signal. The 4G module and the main control are serial communication. In addition, after the geographic coordinate information is input, the geographic location will be displayed. Each 4G module will have a SIM card, which can adapt to China Mobile, China Unicom and China Telecom, and is a full-network signal.

[0055] In this embodiment, the main control box body 1 is connected to the second fixing plate 303 on one side of the second sleeve 302 by threading. At this time, the main control box body 1 is clamped on the rotatable first bracket 3, and the first bracket 3 can rotate around the first sleeve 41 on the second bracket 4 to achieve coordinated rotation with the valve head. Figure 3As shown, the main control box body 1 includes a first upper cover 11, an upper sealing ring 12, a main shell 13, a lower sealing ring 14 and a first base 15. The first upper cover 11 is an irregular polygon with one side concave. In the process of using threads to connect the first upper cover 11 and the main shell 13, the upper sealing ring 12 can reduce wear. The upper end of the main shell 13 is provided with a groove of the same shape as the first upper cover 11. The main control board 131 and the communication board 132 can be placed in the groove respectively. The main control board 131 is located as shown in FIG. Figure 4 As shown in the position, the communication board 132 is located as shown in Figure 6 As shown in the location. Fig. 9 As shown, the lower end of the main housing 13 is a rectangular parallelepiped, which can be loaded with a battery module 133, and the battery module 133 can provide power for various components in the main control box body 1. The lower end of the main housing 13 is also connected to a lower sealing ring 14, and the lower sealing ring 14 can reduce wear during the process of threaded connection between the main housing 13 and the first base 15.

[0056] Therefore, when the valve rotates, the Hall sensor component senses the change in the magnetic field generated by the magnetic pole 43 on the second bracket 4, and the output voltage changes accordingly. At the same time, for the case where the microcontroller component can perform processing and analysis, it can sample and process the output voltage, and determine the rotation direction, number of turns and duration of the valve according to the change in magnetic field strength. The valve rotates clockwise to close, and the valve rotates counterclockwise to open. The valve's rotation direction, number of turns and duration data are transmitted to the remote server through the wireless module on the communication board 132 in the main control box 1 to achieve real-time monitoring.

[0057] In addition, the Beidou positioning module on the communication board 132 in the main control box has a positioning function and uses the Beidou positioning system to display the exact position of the valve well in real time for easy maintenance and inspection.

[0058] In this embodiment, the pipeline vibration sound collector 2 is also clamped on the rotatable first bracket 3 and rotates in coordination with the valve head. Fig.10 As shown, the pipe vibration sound collector 2 is composed of a second upper cover 21, a third fixing plate 22, a pipe vibration sound collector PCB board 221, a metal body 23 and a second base 24. The upper end of the second upper cover 21 is a cylinder with a circular hole in the middle, and the lower end of the second upper cover is a cylindrical cover with a diameter larger than the upper end. A circular third fixing plate 22 is arranged inside the second upper cover 21, and the third fixing plate 22 can be clamped to the pipe vibration sound collector PCB board 221. The metal body 23 includes a thin sheet 231 and a first fixing ring 232. The first fixing ring 232 is connected to multiple layers of the thin sheet 231 at the top and bottom, and can be clamped to the second upper cover 21 and the second base 24 at the top and bottom. As shown Fig.11 and Fig.12 As shown, during the valve monitoring process, the pipeline vibration sound collector PCB board 221 can collect the vibration information of the thin sheet 231 on the metal body 23. The pipeline vibration sound collector PCB board 221 is an existing one, and the model is JIM-00 set by the factory. The second base 24 is cylindrical, and a trapezoidal first protrusion 241 is arranged in the middle of the second base 24. The height of the first protrusion 241 is higher than that of the second base 24, and is used to receive the metal body 23 at the upper end. The outer side of the second base 24 is provided with a second flange 25, which can be threadedly connected to the first flange 331 on the third support rod 33.

[0059] The pipeline vibration sound collector 2 automatically starts at a set time (e.g., 2-4 a.m.) and records sound data for a certain length of time (e.g., 8 minutes). This time period is usually selected during a period with less interference to improve the accuracy of detection. The collected sound signal is converted into digital data and stored in the pipeline vibration sound sensor PCB board 221. The stored sound data is processed by FFT (Fast Fourier Transform) operation on the 8-minute signal data, converting the time domain sound signal into a frequency domain signal to analyze the amplitude of different frequencies. The FFT operation is performed on the U20 component of the main control board 131. The spectrum obtained by the FFT operation identifies the main frequency components, i.e., the dominant frequency bands, which may be related to water leakage or other pipeline problems. The detected dominant frequency bands are compared with the dominant frequency bands in the normal state to determine whether an abnormality has occurred. The amplitudes of all frequency components are integrated to obtain the total amplitude range of each frequency band and compared with the data in the normal state. If the analysis results indicate an abnormality, this information will be transmitted to the IoT platform via a wireless module. After receiving the data, the IoT platform can monitor the status of the valve in real time and issue an alarm when a leak or other abnormality is detected.
