[0030] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings.

[0031] See Figure 1 , Figure 1 which is a structural block diagram of a water volume detection device according to some embodiments of this disclosure. As Figure 1 shown, the water volume detection device 100 includes: at least two Hall sensors 101; and an impeller 102, the impeller 102 including fan blades 1021 and a magnet 1022, the magnet 1022 being disposed on the fan blades 1021; wherein when water flows through the impeller 102, the magnet 1022 rotates together with the fan blades 1021 for the Hall sensors 101 to generate corresponding level signals. The level signals can be used for water volume measurement.

[0032] In some embodiments, the water volume detection device 100 may be provided with only one impeller 102. The impeller 102 includes a plurality of fan blades 1021 and magnets 1022 disposed on each fan blade 1021. As an example, one magnet 1022 may be disposed on each fan blade 1021. In other examples, multiple magnets 1022 may also be disposed on each fan blade 1021. In the embodiments of the present disclosure, by disposing the magnets 1022 on each fan blade 1021, a magnetic field is applied to the Hall sensor. When water flows through the impeller 102, the magnets 1022 rotate together with the fan blades 1021, causing the magnetic field to change. At this time, the Hall sensor 101 can detect the corresponding level signal.

[0033] A Hall sensor is a sensor that uses the Hall effect to detect a magnetic field. When a magnetic field approaches the Hall sensor, the magnetic field affects the current flowing through the inner conductor of the Hall sensor, thereby causing a Hall voltage to be generated in the vertical direction of the Hall sensor. After detecting the Hall voltage, the Hall sensor converts it into a level signal and outputs it.

[0034] In some embodiments, the water volume detection device 100 may be provided with at least two Hall sensors 101. These Hall sensors 101 may be horizontally spaced and disposed on the upper side of the impeller 102 so that when water flows through the impeller 102 for rotational movement, the Hall sensors 101 can detect the corresponding level signals. According to the foregoing settings of the embodiments of the present disclosure, when water flows through the impeller 102 for rotational movement, the water volume detection device 100 can at least detect two sets of level signals, which are respectively obtained by different Hall sensors. It should be noted that in the water pipeline, the Hall sensors are horizontally spaced along the axis of the water flow direction.

[0035] In some embodiments, the sensitive surface of the Hall sensor 101 may be disposed facing the impeller 102 so that the Hall sensor 101 can effectively detect the rotation of the impeller 102 and generate the corresponding level signal.

[0036] In some embodiments, the water volume detection device 100 may further include a controller. The controller communicates with each Hall sensor 101 through a serial port, and is used to receive the level signals detected by the Hall sensor and / or calculate the water volume value according to the level signals.

[0037] In some embodiments, the controller may include a converter for converting each group of level signals received through the serial port into pulse signals to calculate the water volume value according to the pulse signals. Each change in the level signal indicates that a pulse signal is received. Therefore, the level signal can be converted into a pulse signal through the state change of the level signal. For example, when the level signal changes from low to high, it can be defined as the start of a pulse; on the contrary, when the level signal changes from high to low, it can be defined as the end of the pulse.

[0038] In some embodiments, the controller may further include a filter for comparing groups of pulse signals detected by respective Hall sensors 101, identifying abnormal pulse signals, and then filtering out the abnormal pulse signals. According to at least two Hall sensors arranged as described above in this disclosure, at least two groups of pulse signals can be detected simultaneously, enabling the filter to identify abnormal pulse signals by comparing the groups of pulse signals, thereby filtering out the abnormal pulse signals, so that the water volume detection device 100 is protected from abnormal interferences such as abnormal rotation of the impeller 102 driven by water pressure fluctuations, enhancing the anti-interference performance of the water volume detection device and ensuring the accuracy of water volume measurement. The processing flow of the filter can be referred to the description of the water volume detection method in the following text.

[0039] In some embodiments, the controller may further include a meter for calculating the water volume value using the pulse signals. The frequency of the pulse signals is directly proportional to the flow rate of the water. For example, the greater the flow rate of the water, the more pulse signals are generated. Therefore, in some embodiments, the meter can count the number of pulse signals received within a unit time period, i.e., the number of pulses. Multiplying the number of pulses by the unit pulse amount can obtain the water volume value. Herein, the unit time period can be 1 second. As an example, the water volume corresponding to each pulse signal is 1L, and the number of pulses received within the unit time period is 100. Therefore, the product of the water volume and the number of pulses is 100L, and the current water volume value is 100L. In other embodiments, since each pulse signal corresponds to a fixed unit pulse amount, the pulse signals received within the unit time period can be directly counted, and one pulse signal corresponds to one unit pulse amount. Therefore, for each counted pulse signal, the unit pulse amount is accumulated once. Finally, the accumulated result of the unit pulse amount is the water volume value. The processing flow of the meter can be referred to the description of the water volume detection method in the following text.

[0040] In some embodiments, the water volume detection device 100 is usually placed in a closed environment such as a water pipe for measuring the water volume in the closed environment such as a water pipe. The embodiments of this disclosure do not make specific limitations in this regard, and those skilled in the art can use it for water volume measurement in different environments as needed.

[0041] In some embodiments, the water volume detection device 100 may also be communicatively connected to a terminal device using the 485 communication protocol to transmit the detected level signal and / or pulse signal and / or water volume value to the water volume detection device 100 for display based on the 485 communication protocol. The water volume detection device 100 uses the 485 communication protocol for data transmission, which not only has strong anti-interference ability but also fast data transmission efficiency. The terminal device can be an electronic device with a display screen such as a mobile phone, a computer, or a tablet. The embodiments of this disclosure do not make specific limitations in this regard.

[0042] In an embodiment of the present disclosure, at least two Hall sensors 101 are provided in the water volume detection device 100 to detect multiple groups of level signals when water flows through the impeller. Then, after identifying and filtering out abnormal signals through the multiple groups of level signals, water volume measurement is performed, which can enhance the anti-interference performance of the water volume detection device and ensure the accuracy of water volume measurement.

[0043] As described above in conjunction with Figure 1 the water volume detection device 100 of the embodiments of the present disclosure and its multiple embodiments have been described. It can be understood that the above introduction to the water volume detection device 100 is merely exemplary, and those skilled in the art can make modifications to Figure 1 the structure shown therein as needed.

[0044] Refer to Figure 2 , Figure 2 which is a flowchart of the water volume detection method in some embodiments of the present disclosure. As those skilled in the art can understand, Figure 2 the water volume detection method 20 involved can be applied to the water volume detection device described in conjunction with Figure 1 the above.

[0045] As Figure 2 shown, first at step S210, the method 20 converts the first level signal and the second level signal detected by the first Hall sensor and the second Hall sensor into a first pulse signal and a second pulse signal. Each time the level signal changes, it indicates that a pulse signal is received. Therefore, the level signal can be converted into a pulse signal through the state change of the level signal. For example, when the level signal changes from low to high, it can be defined as the start of a pulse; on the contrary, when the level signal changes from high to low, it can be defined as the end of the pulse. In an embodiment of the present disclosure, step S210 can be executed by the converter 1032 of the water volume detection device 100. It can be understood that the first Hall sensor and the second Hall sensor are the Hall sensors 101 configured for the water volume detection device 100.

[0046] Then at step S220, the method 20 identifies abnormal pulse signals in the first pulse signal and / or the second pulse signal according to the induction time of the first pulse signal and the second pulse signal and the first pulse signal and the second pulse signal.

[0047] The Hall sensor closer to the water flow direction will detect the level signal earlier than the Hall sensor farther from the water flow direction. Therefore, the water flow direction can be determined according to the sequence of the induction times of the pulse signals. Determining the water flow direction also means that it can be determined which of the first pulse signal and the second pulse signal is the forward pulse signal and the reverse pulse signal. Furthermore, abnormal pulse signals in the forward pulse signal and / or the reverse pulse signal can be identified through the distribution of the forward pulse signal and the reverse pulse signal.

[0048] It should be noted that the forward pulse signal can be used for water volume measurement. Therefore, the distribution of the forward pulse signal and the reverse pulse signal is mainly used to identify abnormal pulse signals in the forward pulse signal.

[0049] In other embodiments, the water flow direction may also be determined according to the sequence of the induction times of the first level signal and the second level signal. This embodiment does not make specific limitations in this regard, and those skilled in the art can make flexible selections and modifications based on the content and teachings disclosed in this embodiment.

[0050] Subsequently, the process proceeds to step S230. At step S230, method 20 filters out the abnormal pulse signals. In the disclosed embodiment of the present disclosure, method 20 filters out the identified abnormal pulse signals, thereby avoiding the influence of abnormal pulse signals on water volume measurement and reducing the accuracy of water volume measurement. In some embodiments, steps S220 and S230 may be performed by a filter of the water volume detection device.

[0051] Finally, the process reaches step S240. At step S240, method 20 calculates the water volume value using the filtered pulse signals. In the disclosed embodiment of the present disclosure, calculating the water volume value using the forward pulse signals from which the abnormal pulse signals have been filtered can ensure the accuracy of water volume measurement.

[0052] In some embodiments, after performing step S240, method 20 may send the water volume value to the terminal device. Specifically, the water volume value may be sent to the terminal device for display using the 485 communication protocol, so that the user can monitor the water volume value in real time. In addition, method 20 may also send the level signals detected by the Hall sensor and the converted pulse signals to the terminal device for display.

[0053] As an example, refer to Figure 3 , Figure 3 is a flowchart of the water volume detection method for some embodiments of the present disclosure. Figure 3 The water volume detection method 30 shown is a specific implementation manner of steps S220, S230, and S240 described above. As Figure 3As shown, the above step S220 may include steps S301 to S305. First, at step S301, method 30 compares the sequence of induction times of the first pulse signal and the second pulse signal to determine the water flow direction. Among the first pulse signal and the second pulse signal, the pulse signal with an earlier induction time is the forward pulse signal, and the pulse signal with a later induction time is the reverse pulse signal. Then at step S302, method 30 calculates the number of forward pulses per unit time based on the forward pulse signal, and calculates the number of reverse pulses per unit time based on the reverse pulse signal. In some embodiments, the unit time can be set to 1 second. Immediately following, at step S303, method 30 forms a two-dimensional matrix with all the forward pulse numbers and reverse pulse numbers. Thus at step S304, method 30 controls the sliding window to slide on the two-dimensional matrix and determines the distribution of the forward pulse numbers and reverse pulse numbers on the sliding window. Finally, if the distribution is such that the forward pulse numbers and reverse pulse numbers on the sliding window are cross-distributed or do not reach the preset measurement threshold, then step S305 is executed. At step S305, method 30 identifies the forward pulse numbers and reverse pulse numbers on the sliding window as abnormal pulse numbers.

[0054] In the embodiments of the present disclosure, the sliding window can be set as a two-dimensional array with a window width of 5s. Those skilled in the art can change the width of the sliding window as needed. In addition, the dimension of the sliding window can also be set according to the number of Hall sensors set. For example, if the water volume detection device is provided with 3 Hall sensors, then three groups of level signals will be generated, and the dimension of the sliding window can be set to 3.

[0055] In some embodiments, the aforementioned step S230 may include step S306, and step S240 may include step S307. Specifically as Figure 3 shown, after identifying the abnormal pulse numbers, step S306 is executed. At this step S306, method 30 filters out the abnormal pulse numbers. Finally, step S307 is executed. At this time, method 30 calculates the water volume value using the forward pulse numbers in the two-dimensional matrix. It can be understood that although this embodiment can identify abnormal forward pulse numbers and reverse pulse numbers, when calculating the water volume, it is actually calculated based on the forward pulse numbers. Therefore, it is also possible to only filter out the abnormal forward pulse numbers.

[0056] In some embodiments, if the distribution is not such that the forward pulse numbers and reverse pulse numbers on the sliding window are cross-distributed or do not reach the preset measurement threshold, it indicates that there are no abnormal pulse numbers. Then step S306 is skipped and step S307 is directly executed. In some embodiments, step S307 can be executed by the meter of the water volume detection device.

[0057] Specifically, the frequency of the pulse signal is directly proportional to the flow rate of the water. Therefore, in some embodiments, the number of pulse signals received within a unit time duration, i.e., the number of pulses, can be counted. Multiplying the number of pulses by the unit pulse quantity can obtain the water volume value. In other embodiments, since each pulse signal corresponds to a fixed unit pulse quantity, the number of pulses within a unit time duration can be directly counted, and one pulse number corresponds to one unit pulse quantity. Therefore, for each counted pulse number, the unit pulse quantity is accumulated once, and the accumulated result of the unit pulse quantity is the water volume value.

[0058] In the embodiments of the present disclosure, by measuring at least two groups of pulse signals to identify abnormal pulse signals and filtering out the abnormal signals before performing water volume measurement, the accuracy and anti-interference ability of water volume measurement are improved.

[0059] The present disclosure provides a water volume detection system, including a water volume detection device, a memory, a processor, and a computer program stored on the memory and executable on the processor.
