[0038] Figure 1 A schematic diagram of the structure of a flow monitoring device provided in this application embodiment. Figure 1 .like Figure 1 As shown, the flow monitoring device 100 may include: a Hall effect flow sensor 110, a circuit board 120, and a display screen 130.
[0039] In this circuit board 120, analog pin A is connected to analog pin of Hall effect water flow sensor 110 to transmit data collected by Hall effect water flow sensor 110 to circuit board 120. Hall effect water flow sensor 110 is set at a preset position in the water pipe to be monitored to accurately detect the water flow conditions (e.g., water flow velocity, flow rate, etc.) in the water pipe. Digital pin D of circuit board 120 is connected to input pin of display screen 130 to transmit the data processed by circuit board 120 (e.g., water flow velocity, flow rate, etc.) to display screen 130 for display. The preset position of the water pipe to be monitored can be selected according to the actual situation.
[0040] Optionally, the display screen 130 can be selected according to the actual situation; for example, the display screen 130 can be selected as an LCD display screen.
[0041] Optionally, the circuit board 120 can be selected according to the actual situation. For example, the circuit board 120 can be selected as a development board or a control board.
[0042] The flow monitoring device provided in this application comprises a Hall effect water flow sensor, a circuit board, and a display screen. The analog pins of the circuit board are connected to the analog pins of the Hall effect water flow sensor, ensuring that the sensor accurately transmits the detected water flow information to the circuit board as an analog signal. The Hall effect water flow sensor is positioned at a preset location in the water pipe to be monitored, allowing for real-time capture of the water flow dynamics. The digital pins of the circuit board are connected to the input pins of the display screen. The circuit board then transmits the processed data to the display screen as a digital signal for display, achieving real-time monitoring and visualization of the water flow. Furthermore, due to the inherent characteristics of the Hall effect water flow sensor, the flow monitoring device provided in this application offers better flow monitoring accuracy and durability, and can be applied to cost-sensitive applications, increasing the device's applicability and versatility.
[0043] Furthermore, the Hall effect water flow sensor 110 provided in the embodiments of this application will be further illustrated below with reference to the accompanying drawings. Figure 2 A schematic diagram of the structure of a flow monitoring device provided in this application embodiment. Figure 2 .like Figure 2 As shown, the Hall effect water flow sensor 110 may include: a rotating device 111 with a preset magnet and a Hall effect sensor 112.
[0044] The rotating device 111 is installed inside the water pipe to be monitored, and the rotating part of the rotating device 111 is positioned on a preset water flow path so that the preset water flow pushes the rotating part (such as a blade) of the rotating device 111, thereby causing the rotating device 111 to rotate with the water flow. A Hall sensor 112 is installed on the outer wall of the water pipe at a preset position corresponding to the rotating device 111, used to detect the rotation of the rotating device 111 to indirectly measure the water flow, thus realizing real-time monitoring of the water flow. The preset water flow path and preset position can be selected according to actual conditions.
[0045] Optionally, the rotating device 111 can be selected according to the actual situation. For example, the rotating device 111 can be selected as a fan-shaped or propeller-shaped rotating device.
[0046] The flow monitoring device provided in this application comprises a Hall effect water flow sensor consisting of a rotating device with a preset magnet and a Hall effect sensor. The rotating device is positioned inside the water pipe to be monitored, and its rotating part is located on a preset water flow path, ensuring that the rotating part is precisely positioned along the path. When water flows through, the water flow drives the rotating part to rotate. The Hall effect sensor is positioned on the outer wall of the water pipe at a preset location corresponding to the rotating device, allowing the Hall effect sensor to detect the magnetic field changes generated by the preset magnet rotating with the water flow non-contactly. Therefore, the Hall effect water flow sensor provided in this application achieves accurate monitoring of the water flow state within a preset water pipe by combining the coordinated operation of the rotating device and the Hall effect sensor. The rotating device rotates with the water flow, and the Hall effect sensor captures the changes in the magnetic field during rotation, thus providing a reliable data basis for measuring water flow parameters. Furthermore, based on the principle of the Hall effect, there are no mechanically worn parts, resulting in a long service life, good anti-interference capabilities, and stable operation in complex environments.
[0047] Optionally, in one possible embodiment, a preset magnet is provided at the end of the target rotating part among the plurality of rotating parts on the rotating device 111, and some rotating parts of the plurality of rotating parts are located on a preset water flow path.
[0048] In one possible implementation, continue to refer to Figure 2 In the rotating device 111, a preset magnet is provided at the end of the target rotating part among the multiple rotating parts. Parts of the multiple rotating parts are positioned on a preset water flow path, so that when the multiple rotating parts in the rotating device 111 rotate, the position of the preset magnet at the end of the target rotating part changes, generating a voltage difference. Based on this voltage difference, a Hall sensor 112 at a preset position on the outer wall of the water pipe to be monitored, corresponding to the rotating device 111, generates a pulse signal. The Hall sensor 112 can be used to transmit the voltage difference and the pulse signal to the circuit board 120. The preset magnet can be selected according to actual conditions.
[0049] The flow monitoring device provided in this application includes a target rotating part on a rotating device, with a preset magnet at its end. Some of the rotating parts are positioned along a preset water flow path to ensure that the rotating parts are effectively driven to rotate when water flows through them. Because the target rotating part has a preset magnet at its end, the position of the preset magnet changes as the rotating part rotates under the influence of the water flow. This dynamic process provides a basis for detection by an externally mounted Hall effect sensor, thereby achieving accurate monitoring of the water flow state.
[0050] Alternatively, in one possible implementation, reference may continue to be made to the above. Figure 1 The flow monitoring device 100 may further include a first wire S1 and a second wire S2. The analog pins of the circuit board 120 are connected to the analog pins of the Hall effect water flow sensor 110 via the first wire S1, so as to transmit the data collected by the Hall effect water flow sensor 110 to the circuit board 120 via the first wire S1. The digital pins of the circuit board 120 are connected to the input pins of the display screen 130 via the second wire S2, so as to transmit the data processed by the circuit board 120 (such as water flow velocity, flow rate, etc.) to the display screen 130 for display via the second wire S2.
[0051] The first wire S1 is used to transmit analog signals; the second wire S2 is used to transmit digital signals.
[0052] The flow monitoring device provided in this application can also be composed of a first wire and a second wire. The analog pins of the circuit board are connected to the analog pins of the Hall effect flow sensor via the first wire, ensuring that the Hall effect flow sensor can accurately transmit the detected water flow information to the circuit board in the form of an analog signal. The digital pins of the circuit board are connected to the input pins of the display screen via the second wire, so that the processed data is transmitted to the display screen in the form of a digital signal for display, realizing real-time monitoring and visualization of the water flow. Furthermore, connecting the Hall effect flow sensor, circuit board, and display screen via wires facilitates assembly and installation.
[0053] The flow monitoring device 100 provided in the embodiments of this application will be further described below with reference to the accompanying drawings. Figure 3 A schematic diagram of the structure of a flow monitoring device provided in this application embodiment. Figure 3 .like Figure 3 As shown, the flow monitoring device 100 may further include a power supply module 140.
[0054] The power module 140 is connected to the power pins of the circuit board 120, the Hall flow sensor 110, and the display screen 130, respectively, to provide the Hall flow sensor 110, the circuit board 120, and the display screen 130 with electrical signals that enable normal operation.
[0055] The flow monitoring device provided in this application may also be composed of a power supply module; wherein, the power supply module is connected to the power supply pins of the circuit board, the power supply pins of the Hall flow sensor and the power supply pins of the display screen, respectively, to provide the Hall flow sensor, the circuit board and the display screen with electrical signals that enable normal operation, and to ensure the normal operation of the flow monitoring device.
[0056] Alternatively, in one possible implementation, reference may continue to be made to the above. Figure 3 The flow monitoring device 100 may also include a third conductor S3.
[0057] The power module 140 is connected to the power pins of the circuit board 120, the Hall flow sensor 110, and the display screen 130 via the third wire S3, so as to provide the Hall flow sensor 110, the circuit board 120, and the display screen 130 with electrical signals that can work normally through the connection of the third wire S3.
[0058] The third wire S3 is a dual-phase wire, used to connect the power supply pins of the circuit board, the power supply pins of the Hall effect water flow sensor, and the power supply pins of the display screen.
[0059] The flow monitoring device provided in this application may also include a third wire; wherein, the power module is connected to the power pin of the circuit board, the power pin of the Hall flow sensor, and the power pin of the display screen through the third wire, so as to provide the Hall flow sensor, the circuit board and the display screen with an electrical signal that can work normally through the third wire, thereby ensuring the normal operation of the flow monitoring device.
[0060] The flow monitoring device 100 provided in the embodiments of this application will be further described below with reference to the accompanying drawings. Figure 4 A schematic diagram of the structure of a flow monitoring device provided in this application embodiment. Figure 4 .like Figure 4 As shown, the flow monitoring device 100 may further include a breadboard 150.
[0061] The display screen 130 is fixedly mounted on the breadboard 150 to ensure the stability of the display screen 130 and to facilitate testing and debugging of the display screen 130.
[0062] The flow monitoring device provided in this application may also be composed of a breadboard; the display screen is fixedly mounted on the breadboard to increase the stability of the display screen and facilitate testing and debugging of the display screen.
[0063] Furthermore, to facilitate understanding of the above-described flow monitoring device, this application embodiment also provides an example of a flow monitoring method, which may include:
[0064] The first step is to acquire the output pulse signal of the Hall effect flow sensor.
[0065] The second step is to calculate the water flow velocity based on the pulse signals. For example, if a Hall effect water flow sensor outputs approximately 4.5 pulses per minute per liter of liquid passing through, then the water flow velocity (L / hr) = number of pulses per hour ÷ (4.5 × 60), which calculates the volume of liquid flowing through per hour, i.e., the flow velocity. For example, if 1620 pulses are detected in one hour, then the flow velocity = 1620 ÷ (4.5 × 60) = 6 (L / hr).
[0066] It should be noted that the total flow rate of the liquid is based on the cumulative number of pulses over the entire measurement period. Combining the above correspondence between pulse signals and flow rates, the total volume of liquid flowing through can be calculated (in liters). For example, if a total of 3600 pulses are accumulated from the start of the measurement to a certain moment, then the total flow rate = 3600 ÷ 4.5 = 800 (liters).
[0067] The third step is to transmit the water flow rate to a display screen for visual monitoring by staff.
[0068] The flow monitoring method provided in this application acquires the output pulse signal of a Hall effect flow sensor, calculates the flow velocity based on the pulse signal, and transmits the flow velocity to a display screen for display. Therefore, this application achieves liquid flow monitoring and improves the reliability of the flow monitoring device.
[0069] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
