Description

Technical Field

[0001] The present invention relates to the technical field of electrical communications, and in particular to a water use anomaly detection system and a control method. Background Art

[0002] The induction flusher is a commonly used flushing device for squat toilets. Its water valve is mostly a solenoid valve, and the flushing and water shut-off are directly controlled by the solenoid valve.

[0003] When a solenoid valve fails and the valve cannot be closed normally, or when the connection between the flusher and the water inlet of the water pipe is not tightly closed, it will cause water leakage, resulting in a waste of water resources. At the same time, when the solenoid valve fails and the valve cannot be opened, the flushing function of the flusher fails and is useless. Especially when it occurs in the bathroom in public areas, these flusher failures are difficult to be discovered in time. At the same time, since the induction flushers in related technologies are all off-grid, they cannot communicate and interact remotely. They can only be repaired and handled through manual inspections during manual inspections.

[0004] Therefore, how to automatically detect the induction flusher and send the detection results in time is currently an urgent problem to be solved. Summary of the invention

[0005] The object of the present invention is to provide a water use anomaly detection system and a control method.

[0006] In order to solve the above technical problems, the present invention provides a water use anomaly detection system, comprising:

[0007] Server, detection terminal and induction flusher body;

[0008] The server is communicatively connected with the detection terminal;

[0009] The detection terminal is suitable for collecting sound data during the flushing process of the induction flusher body, and performing an initial judgment on the sound data, and after judging that the sound data is abnormal, sending the sound data to the server;

[0010] The server is adapted to make a final judgment based on the sound data, obtain a judgment result, and issue a maintenance signal based on the judgment result;

[0011] The detection terminal includes: a communication module, a control module, a first acquisition module, and a second acquisition module;

[0012] The control module is electrically connected to the communication module, the first acquisition module and the second acquisition module respectively;

[0013] The control module is adapted to control the induction flusher body to flush water upon receiving a detection instruction;

[0014] The control module is also adapted to control the first acquisition module or the second acquisition module to collect sound data during the flushing process of the induction flusher body according to the determination condition;

[0015] The control module is adapted to perform an initial judgment based on the received sound data, and after judging that the sound data is abnormal, send the sound data to the server.

[0016] Further, the determination condition includes: obtaining a first flag F1, a second flag F2, a third flag F3 and a fourth flag F4 for determination required to start the corresponding acquisition module;

[0017] The first acquisition module or the second acquisition module is controlled according to the determination condition to collect the sound data of the induction flusher body during the flushing process, that is,

[0018] First, determine whether any one of the third flag F3 and the fourth flag F4 exists;

[0019] If it exists, the first acquisition unit is turned on to collect sound data; if it does not exist, it continues to determine whether any one of the first flag F1 and the second flag F2 exists;

[0020] If it does not exist, the first acquisition unit is started to collect sound data; if it does exist, the second acquisition unit is started to collect sound data.

[0021] Furthermore, the power consumption of the first acquisition unit is less than that of the second acquisition unit, and the acquisition accuracy of the first acquisition unit is less than that of the second acquisition unit.

[0022] Furthermore, the control module is adapted to perform a step of initially judging based on the received sound data, including:

[0023] If the control module receives the sound data collected by the first collection unit, the sound data is processed and the first flag F1, the second flag F2, the third flag F3 and the fourth flag F4 are updated;

[0024] If the control module receives the sound data collected by the second collecting unit, the first flag F1 and the second flag F2 are updated.

[0025] Furthermore, if the control module receives the sound data collected by the first collection unit, the sound data is processed and the first flag F1, the second flag F2, the third flag F3 and the fourth flag F4 are updated, namely:

[0026] The sound data collected by the first collection unit is denoised, and the flushing sound intensity value S1 and the stop flushing sound intensity value S1 are calculated based on the denoised sound data. h ;

[0027] The sound intensity value of flushing water S1 and the sound intensity value of stopping flushing water S h Make judgments;

[0028] If the flushing sound intensity value S1 is less than the first parameter H st , then update the cumulative value m1, so that the cumulative value m1 plus one; if the flushing sound intensity value S1 is greater than the first parameter H st , then update the cumulative value m1, clear the cumulative value m1, clear the existing first flag F1 and third flag F3, and complete the detection;

[0029] If the flushing sound intensity value S is stopped this time h Greater than the second parameter H lt , then update the cumulative value m2, so that the cumulative value m2 plus one; if the flushing sound intensity value S is stopped this time h Less than the second parameter H lt , then update the cumulative value m2, clear the cumulative value m2, clear the existing second flag F2 and fourth flag F4, and complete the detection;

[0030] The accumulated value m1 and the accumulated value m2 are judged. If the accumulated value m1 is greater than the first set number of times M, the first flag F1 is marked. If the accumulated value m2 is greater than the first set number of times M, the second flag F2 is marked to complete the detection.

[0031] Furthermore, the control module is also adapted to control the first parameter H st And the second parameter H lt To perform a real-time update, you need to:

[0032] Record the flushing sound intensity value S1 and the stop flushing sound intensity value S1 of the induction flusher body during the last n times h ;

[0033] Calculate the maximum value S among n flushing sound intensity values ​​S1 1max =MAX(S 11 , S 12 …S 1n ) and N stop flushing sound intensity values ​​S h The minimum value S in hmin =MIN(S h1 , S h2 …S hn );

[0034] The updated first parameter H st =S 1max *β, the second parameter H 1t=S hmin *α;

[0035] Wherein, n is the second set number of times, the value range is between 5 and 10, α and β are correction coefficients, 0<β<1, α>1.

[0036] Furthermore, if the control module receives the sound data collected by the second collection unit, the step of updating the first flag F1 and the second flag F2 is as follows:

[0037] If the first flag F1 exists and the third flag F3 does not exist, the control module controls the second acquisition unit to perform acquisition, receives the sound data acquired by the second acquisition unit, and increases the value of the continuous acquisition times k1 by one;

[0038] If the second flag F2 exists and the fourth flag F3 does not exist, the control module controls the second acquisition unit to perform acquisition, receives the sound data acquired by the second acquisition unit, and increases the value of the continuous acquisition times k2 by one;

[0039] When the continuous acquisition times k1 is greater than the third set times K, the third flag F3 is marked and k1 is cleared; when the continuous acquisition times k2 is greater than the third set times K, the fourth flag F4 is marked and k2 is cleared.

[0040] Further, the server is adapted to make a final judgment based on the sound data, obtain a judgment result, and issue a maintenance signal based on the judgment result, that is:

[0041] receiving sound data;

[0042] Extracting spectral features of sound data;

[0050] The second solenoid valve is respectively connected to the first switching mechanism and the second switching mechanism to form a secondary flushing water pipeline;

[0051] The water inlet pipe is arranged on the top of the first switching mechanism and is communicated with the first switching mechanism;

[0052] The water outlet pipe is arranged at the bottom of the second switching mechanism and is communicated with the second switching mechanism;

[0053] The detection terminal is adapted to control the first switching mechanism and the second switching mechanism to close the main flushing water pipeline and open the auxiliary flushing water pipeline after receiving the maintenance signal sent by the server.

[0054] Furthermore, the first switching mechanism includes:

[0055] A first box body, a first magnetic sliding blocking block and a first driving box;

[0056] The first magnetic sliding blocking block is slidably disposed in the first box;

[0057] The first driving box is arranged on the outer wall of the first box body and between the main flushing water pipeline and the auxiliary flushing water pipeline;

[0058] Three first magnetic attraction coils are arranged side by side in the first driving box;

[0059] When the three first magnetic attraction coils are powered on, they respectively attract the first magnetic sliding blocking block to the corresponding first working point, second working point and third working point;

[0060] When the first magnetic sliding blocking block slides to the first working point, it is suitable for blocking the main flushing water pipeline and connecting the water inlet pipe with the auxiliary flushing water pipeline;

[0061] When the first magnetic sliding blocking block slides to the second working point, it is suitable for blocking both the main flushing pipeline and the water inlet pipe;

[0062] When the first magnetic sliding blocking block slides to the third working point, it is suitable for blocking the auxiliary flushing water pipeline and connecting the water inlet pipe with the main flushing water pipeline;

[0063] The second switching mechanism comprises:

[0064] A second box body, a second magnetic sliding blocking block and a second driving box;

[0065] The second magnetic sliding blocking block is slidably disposed in the second box;

[0066] The second driving box is arranged on the outer wall of the first box body and between the main flushing water pipeline and the auxiliary flushing water pipeline;

[0067] Three second magnetic coils are arranged side by side in the second driving box;

[0068] The three second magnetic attraction coils respectively attract the second magnetic sliding blocking block to the fourth working point, the fifth working point and the sixth working point when powered on;

[0069] When the second magnetic sliding blocking block slides to the fourth working point, it is suitable for blocking the main flushing water pipeline and connecting the water outlet pipe with the auxiliary flushing water pipeline;

[0070] When the second magnetic sliding blocking block slides to the fifth working point, it is suitable for blocking both the main flushing pipeline and the water outlet pipe;

[0071] When the second magnetic sliding blocking block slides to the sixth working point, it is suitable for blocking the auxiliary flushing water pipeline and connecting the water outlet pipe with the main flushing water pipeline;

[0072] A third magnetic coil is provided on one side of the second box body close to the main flushing pipe;

[0073] When the third magnetic attraction coil is energized, the second magnetic sliding blocking block is attracted to the seventh working point;

[0074] When the second magnetic sliding blocking block slides to the seventh working point, the second magnetic sliding blocking block fits against the side wall of the second box body, and at this time, the main flushing water pipeline and the auxiliary flushing water pipeline are both connected to the water outlet pipe.

[0075] Furthermore, the induction flusher body includes five working conditions, namely:

[0076] In the first working condition, the detection terminal controls the first magnetic sliding blocking block to slide to the third working point, and the second magnetic sliding blocking block to slide to the sixth working point. At this time, the main flushing water pipeline is connected and the auxiliary flushing water pipeline is blocked;

After the detection terminal receives the detection instruction, the second magnetic sliding blocking block is controlled to slide to the seventh working point to complete flushing. After the flushing is completed, the second magnetic sliding blocking block is controlled to slide to the fifth working point to continue to store water and wait for the next detection instruction.

DETAILED DESCRIPTION

[0099] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention. Figure 1 At least one embodiment provides a water use abnormality detection system, including: a server, a detection terminal and an induction flusher body; the server is communicatively connected to the detection terminal; the detection terminal is suitable for collecting sound data during the flushing process of the induction flusher body, and performing an initial judgment on the sound data, and after judging that the sound data is abnormal, sending the sound data to the server; the server is suitable for making a final judgment based on the sound data, obtaining a judgment result, and sending a maintenance signal based on the judgment result. The flushing process of the induction flusher body is initially judged by the detection terminal, and after judging that the sound data is abnormal, it is sent to the server for final judgment. The two-level judgment process can not only improve the accuracy of the abnormal water use detection result of the induction flusher body, but also send the abnormal information in time to remind the staff to perform maintenance and repair the induction flusher body, which is more timely than manual inspection, and at the same time, reduces labor costs and reduces the waste of water resources.

[0100] See also Figure 2In a preferred embodiment, the detection terminal includes: a communication module, a control module, a first acquisition module, and a second acquisition module; the control module is electrically connected to the communication module, the first acquisition module, and the second acquisition module respectively; the control module is suitable for controlling the induction flusher body to flush water when receiving a detection instruction; the control module is also suitable for controlling the first acquisition module or the second acquisition module to collect sound data during the flushing process of the induction flusher body according to a judgment condition; the control module is suitable for making an initial judgment based on the received sound data, and after judging that the sound data is abnormal, sending the sound data to the server.

[0101] In some embodiments, the power consumption of the first acquisition unit is less than that of the second acquisition unit, and the acquisition accuracy of the first acquisition unit is less than that of the second acquisition unit. The control module makes an initial judgment through the low-power and low-precision first acquisition module, and after judging the abnormality, collects sound data through the high-precision second acquisition module and transmits it to the server for final judgment, which reduces the overall cost of the detection terminal on the one hand, and reduces the power consumption of the detection terminal on the other hand.

[0102] It should be noted that the detection instruction may be that after the induction flusher body senses the need for flushing, the detection instruction is sent to the control module, at which time the induction flusher body is controlled to flush. Alternatively, multiple time points are preset to perform leakage detection when the induction flusher is in standby mode. When the preset time arrives, the control module receives the detection instruction and directly controls the first acquisition module or the second acquisition module to collect the sound data of the induction flusher body according to the judgment conditions.

[0103] The working state of the induction flusher is prioritized over the leakage detection at the preset time point, that is, after the induction flusher body senses that flushing is needed, if a leakage detection is being performed at this time, the leakage detection is abandoned and the flushing process of the induction flusher is detected instead. The preset multiple time points are generally set between 1 am and 3 am.

[0104] like Figure 3 As shown, the determination condition includes: obtaining the first flag F1, the second flag F2, the third flag F3 and the fourth flag F4 required for starting the corresponding acquisition module; wherein, the first acquisition module or the second acquisition module is controlled according to the determination condition to collect the sound data of the flushing process of the induction flusher body, that is:

[0105] Determine whether any one of the third flag F3 and the fourth flag F4 exists;

[0106] If it exists, the first acquisition unit is turned on to collect sound data; if it does not exist, it continues to determine whether any one of the first flag F1 and the second flag F2 exists;

[0107] If it does not exist, the first acquisition unit is started to collect sound data; if it exists, the second acquisition unit is started to collect sound data.

[0108] It should be noted that the first mark F1, the second mark F2, the third mark F3 and the fourth mark F4 are determination marks marked after the control module determines during the flushing process of the induction flusher body.

[0109] The following is an explanation of the processing steps after the control module receives the data sent by different acquisition modules. In a preferred embodiment, the control module is adapted to perform the initial judgment based on the received sound data, including:

[0110] The first type: if the control module receives the sound data collected by the first collection unit, the sound data is processed and the first flag F1, the second flag F2, the third flag F3 and the fourth flag F4 are updated;

[0111] The second type: if the control module receives the sound data collected by the second collecting unit, the first flag F1 and the second flag F2 are updated.

[0112] See also Figure 4 , if the control module receives the sound data collected by the first collection unit, the sound data is processed and the first flag F1, the second flag F2, the third flag F3 and the fourth flag F4 are updated, that is:

[0113] S110: De-noising the sound data collected by the first collection unit, and calculating the flushing sound intensity value S1 and the stop flushing sound intensity value S2 according to the de-noised sound data. h .

[0114] The flushing sound intensity value S1 represents the water sound intensity value in the pipe after the flusher starts flushing; the flushing sound intensity value S h Indicates the sound intensity of water in the pipe after the flusher is closed.

[0115] Specifically, the sound intensity value S = 20lg U1 / U2, where U1 is the voltage mean square value of the sound data collected, and U2 is the reference voltage value. The reference voltage is set according to the characteristics of the audio acquisition module. In this example, the voltage value can also be a current value or other electrical value, which can be determined according to the characteristics of the acquisition module.

[0116] Substitute the corresponding U1 and U2 into the sound intensity value formula to calculate the flushing sound intensity value S1 and the stop flushing sound intensity value S h .

[0117] S120: flushing sound intensity value S1 and stop flushing sound intensity value S h Make a judgment.

[0118] S130: If the flushing sound intensity value S1 is less than the first parameter H st , then update the cumulative value m1, so that the cumulative value m1 plus one; if the flushing sound intensity value S1 is greater than the first parameter H st , then update the cumulative value m1, clear the cumulative value m1, clear the existing first flag F1 and third flag F3, and complete the detection.

[0119] S140: If the flushing sound intensity value S is stopped h Greater than the second parameter H lt , then update the cumulative value m2, so that the cumulative value m2 plus one; if the flushing sound intensity value S is stopped this time h Less than the second parameter H lt , then update the accumulated value m2, clear the accumulated value m2, clear the existing second flag F2 and fourth flag F4, and complete the detection.

[0120] S150: judging the accumulated value m1 and the accumulated value m2, if the accumulated value m1 is greater than the first set number of times M, marking the first flag F1, if the accumulated value m2 is greater than the first set number of times M, marking the second flag F2, and completing the detection.

[0121] It should be noted that the first set number M is a set value. In some embodiments, the first set number M ranges from 3 to 5.

[0122] After the detection is completed, the control module is also suitable for adjusting the first parameter H st And the second parameter H lt To perform a real-time update, you need to:

[0123] Record the flushing sound intensity value S1 and the stop flushing sound intensity value S1 of the induction flusher body during the last n times h ;

[0124] Calculate the maximum value S among n flushing sound intensity values ​​S1 1max =MAX(S 11 , S 12 …S 1n ) and N stop flushing sound intensity values ​​S h The minimum value S in hmin =MIN(S h1 , S h2 …S hn);

[0125] The updated first parameter H st =S 1max *β, the second parameter H 1t =S hmin *α;

[0126] Wherein, n is the second set number of times, the value range is between 5 and 10, α and β are correction coefficients, 0<β<1, α>1.

[0127] See also Figure 5 , if the control module receives the sound data collected by the second collection unit, the step of updating the first flag F1 and the second flag F2 is:

[0128] S210: If the first flag F1 exists and the third flag F3 does not exist, the control module controls the second acquisition unit to perform acquisition, receives the sound data acquired by the second acquisition unit, and increases the value of the continuous acquisition times k1 by one;

[0129] S220: If the second flag F2 exists and the fourth flag F3 does not exist, the control module controls the second acquisition unit to perform acquisition, receives the sound data acquired by the second acquisition unit, and increases the value of the continuous acquisition number k2 by one;

[0130] S230: When the continuous acquisition number k1 is greater than the third set number K, the third flag F3 is marked and k1 is cleared; when the continuous acquisition number k2 is greater than the third set number K, the fourth flag F4 is marked and k2 is cleared.

[0131] It should be noted that the third set number K is a set value. In some embodiments, the first set number M ranges from 3 to 5.

[0132] See also Figure 6 The server is adapted to make a final judgment based on the sound data, obtain a judgment result, and issue a maintenance signal based on the judgment result. Specifically, the following steps are included:

[0133] S310: Receive sound data.

[0134] S320: Extracting frequency spectrum features of the sound data.

[0135] Specifically, the server converts the sound data into a spectrogram and normalizes it to obtain the spectrum features.

[0136] S330: Input the spectrum features into the corresponding convolutional neural network model respectively to obtain the recognition result.

[0137] Specifically, there is a corresponding convolutional neural network model for flushing anomaly and water leakage, which are used to identify flushing anomaly and water leakage of the sensor flusher body respectively.

[0138] The two convolutional neural network models were trained using the following method:

[0139] Obtain training samples, collect the sound data of abnormal flushing and the sound data of flushing leakage, generate corresponding spectrograms, and then normalize the spectrograms. The two types of images obtained are training samples. Randomly extract parts of the two types of training samples to train the initial convolutional neural network model respectively, so as to obtain two convolutional neural network models.

[0140] S340: If the identification result is that the sensor flusher body is blocked or leaking, a maintenance signal is issued.

[0141] See also Figure 7 In at least one embodiment, the induction flusher body includes: an inlet pipe 110, an outlet pipe 120, a first switching mechanism 130, a second switching mechanism 140, a first solenoid valve 150 and a second solenoid valve 160; the first switching mechanism 130 and the second switching mechanism 140 are arranged opposite to each other; the first solenoid valve 150 and the second solenoid valve 160 are arranged side by side and between the first switching mechanism 130 and the second switching mechanism 140.

[0143] Please continue reading Figure 7 and Figure 8 , the structures of the first switching mechanism 130 and the second switching mechanism 140 are described below.

[0144] The first switching mechanism 130 includes: a first box body 131, a first magnetic sliding blocking block 132 and a first driving box 133; the first magnetic sliding blocking block 132 is slidably set in the first box body 131; the first driving box 133 is set on the outer wall of the first box body 131, and is set between the main flushing pipeline and the auxiliary flushing pipeline; three first magnetic attraction coils are arranged side by side in the first driving box 133; when the three first magnetic attraction coils are energized, they respectively adsorb the first magnetic sliding blocking block 132 to the corresponding first working point 134, the second working point 135 and the third working point 136.

[0145] It should be noted that whether the three first magnetic attraction coils are energized is controlled by the control module.

[0146] When the first magnetic sliding blocking block 132 slides to the first working point 134, it is suitable for blocking the main flushing water pipeline and connecting the water inlet pipe 110 with the auxiliary flushing water pipeline; when the first magnetic sliding blocking block 132 slides to the second working point 135, it is suitable for blocking both the main flushing water pipeline and the water inlet pipe 110; when the first magnetic sliding blocking block 132 slides to the third working point 136, it is suitable for blocking the auxiliary flushing water pipeline and connecting the water inlet pipe 110 with the main flushing water pipeline.

[0147] The second switching mechanism 140 includes: a second box body 141, a second magnetic sliding blocking block 142 and a second driving box 143; the second magnetic sliding blocking block 142 is slidably set in the second box body 141; the second driving box 143 is set on the outer wall of the first box body 131, and is set between the main flushing pipeline and the auxiliary flushing pipeline; three second magnetic attraction coils are arranged side by side in the second driving box 143; when the three second magnetic attraction coils are energized, they respectively adsorb the second magnetic sliding blocking block 142 to the fourth working point 144, the fifth working point 145 and the sixth working point 146.

[0148] When the second magnetic sliding blocking block 142 slides to the fourth working point 144, it is suitable for blocking the main flushing water pipeline and connecting the outlet pipe 120 with the auxiliary flushing water pipeline; when the second magnetic sliding blocking block 142 slides to the fifth working point 145, it is suitable for blocking both the main flushing water pipeline and the outlet pipe 120; when the second magnetic sliding blocking block 142 slides to the sixth working point 146, it is suitable for blocking the auxiliary flushing water pipeline and connecting the outlet pipe 120 with the auxiliary flushing water pipeline. The main flushing water pipeline is connected; a third magnetic attraction coil is arranged on one side of the second box body 141 close to the main flushing water pipeline; when the third magnetic attraction coil is energized, the second magnetic sliding blocking block 142 is adsorbed to the seventh working point 147; when the second magnetic sliding blocking block 142 slides to the seventh working point 147, the second magnetic sliding blocking block 142 fits with the side wall of the second box body 141, and at this time, the main flushing water pipeline and the auxiliary flushing water pipeline are both connected to the water outlet pipe 120.

[0149] In some embodiments, the induction flusher body includes five working conditions, namely:

[0150] In the first working condition, the detection terminal controls the first magnetic sliding blocking block 132 to slide to the third working point 136, and the second magnetic sliding blocking block 142 to slide to the sixth working point 146. At this time, the main flushing water pipeline is connected and the auxiliary flushing water pipeline is blocked.

[0151] In the second working condition, the detection terminal receives a maintenance signal. At this time, the detection terminal controls the first magnetic sliding blocking block 132 to slide to the first working point 134, and the second magnetic sliding blocking block 142 to slide to the fourth working point 144. At this time, the main flushing water pipeline is blocked and the auxiliary flushing water pipeline is connected. By setting the first magnetic sliding blocking block 132 and the second magnetic sliding blocking block 142, both ends of the main flushing water pipeline are blocked, and the auxiliary flushing water pipeline is connected, so as not to affect the normal use of the induction flusher body.

[0152] In the third working condition, the detection terminal receives the replacement signal of the first solenoid valve 150. At this time, the detection terminal controls the first magnetic sliding blocking block 132 to slide to the second working point 135, and the second magnetic sliding blocking block 142 to slide to the fifth working point 145. At this time, the main flushing water pipeline and the water inlet pipe 110 are blocked, and the main flushing water pipeline and the water outlet pipe 120 are blocked. After the second solenoid valve 160 is replaced to the main flushing water pipeline, the detection terminal receives the replacement completion signal and turns the induction flusher body into the first working condition for operation. When the first solenoid valve 150 needs to be replaced, the water inlet pipe 110 and the water outlet pipe 120 are blocked, the second solenoid valve 160 as a spare part is removed, and the interface between the auxiliary flushing water pipeline and the second solenoid valve 160 is blocked. After that, the first solenoid valve 150 is removed, and the second solenoid valve 160 is installed in the main flushing water pipeline to complete the replacement of the first solenoid valve 150. Each time when replacing, there is no need to look for spare parts, and the spare parts can be directly removed from the induction flusher body. At the same time, the second solenoid valve 160 as a spare part can also play a role of temporary bypass when the first solenoid valve 150 is damaged.

[0153] In the fourth working condition, the detection terminal receives the replacement signal of the second solenoid valve 160. At this time, the detection terminal controls the first magnetic sliding blocking block 132 to slide to the second working point 135, and the second magnetic sliding blocking block 142 to slide to the fifth working point 145. At this time, the main flushing pipeline and the water inlet pipe 110 are blocked, and the main flushing pipeline and the water outlet pipe 120 are blocked. The new second solenoid valve 160 is replaced in the auxiliary flushing pipeline. The detection terminal receives the replacement completion signal and turns the induction flusher body into the first working condition for operation. The second solenoid valve 160 of the induction flusher that lacks the second solenoid valve 160 is replaced regularly.

[0154] In the fifth working condition, the detection terminal receives a water storage instruction. At this time, the detection terminal controls the first magnetic sliding blocking block 132 to slide to the third working point 136, and the second magnetic sliding blocking block 142 to slide to the fifth working point 145. At this time, the water inlet pipe 110, the first box 131 and the main flushing pipeline are connected, and the main flushing pipeline and the water outlet pipe 120 are blocked to complete water storage. After the detection terminal receives the detection instruction, the second magnetic sliding blocking block 142 is controlled to slide to the seventh working point 147 to complete flushing. After the flushing is completed, the second magnetic sliding blocking block 142 is controlled to slide to the fifth working point 145 to continue to store water and wait for the next detection instruction. The first box body 131 is provided to store water and buffer the water pressure. When the water pressure is insufficient, water is stored through the first box body 131 to meet the pressure requirement during flushing. When the water pressure is too high, the second box body 141 is used for buffering. The liquid first flows into the second box body 141 and then flushes through the water outlet to avoid damage to the squat toilet caused by excessive water pressure.

[0155] like Fig. 9 As shown, at least one embodiment further provides a control method for the water use anomaly detection system as described above, characterized in that the method comprises:

[0156] S410: receiving a detection instruction;
