[0041] In one embodiment, Figure 3 As shown, a water purification equipment fault detection method is provided, and the method is applied to Figure 2 Taking the server 202 in the example as an example, the following steps are included:

[0042] Step 302, obtaining a first flow meter reading of a flow meter deployed in a non-faulty water purification device.

[0043] The non-faulty water purification device and the target water purification device are not the same device, and the device structures of the non-faulty water purification device and the target water purification device may be the same or different, which is not limited here.

[0044] Among them, the flow meter readings involved in the full text (including the first flow meter reading and the second flow meter reading mentioned above) may include pulse readings, electrical parameter readings, and flow readings. The electrical parameter readings include but are not limited to current readings and voltage readings.

[0045] As an embodiment, step 302 includes: obtaining a first pulse reading, a first electrical parameter reading, or a first flow reading when the flow meter is deployed in a non-faulty water purification device.

[0046] Step 304: Detect the operation fault of the flow meter according to the first flow meter reading to obtain flow meter fault detection information of the flow meter.

[0047] Among them, the flow meter fault detection information in step 304 may include a flow meter fault detection label, and may also include a flow meter fault risk value. The flow meter fault detection label includes a fault label or a fault label. The flow meter fault risk value is used to characterize the risk level of a flow meter fault.

[0048] Exemplarily, step 304 includes: converting the first flow meter reading into a first flow value, and detecting an operation fault of the flow meter according to the first flow value to obtain flow meter fault detection information of the flow meter.

[0049] As an embodiment, converting the first flow meter reading into the first flow value includes: when the first flow meter reading includes the first flow reading, determining the first flow reading as the first flow value.

[0050] As another embodiment, converting a first flow meter reading into a first flow value includes: when the first flow meter reading includes a pulse reading, obtaining a pulse coefficient corresponding to the first flow meter, and converting the pulse reading into the first flow value based on the pulse coefficient. Specifically, the product of the pulse coefficient and the pulse reading is determined as the first flow value.

[0051] As another embodiment, converting the first flow meter reading into the first flow value includes: when the first flow meter reading includes an electrical parameter reading, obtaining a mapping relationship corresponding to the first flow meter, wherein the mapping relationship includes a corresponding relationship between the electrical parameter value and the flow value, and converting the electrical parameter reading included in the first flow meter reading into the first flow value through the mapping relationship. For example, the current range of the flow meter is 0-10mA, and the flow value range is 0%-100%. When the electrical parameter reading included in the first flow meter reading is 0mA, the converted first flow value is 0%, and when the electrical parameter reading included in the first flow meter reading is 10mA, the converted first flow value is 100%; the voltage range of the flow meter is 0-5V, and the flow value range is 0%-100%. When the electrical parameter reading included in the first flow meter reading is 0V, the converted first flow value is 0%, and when the electrical parameter reading included in the first flow meter reading is 5V, the converted first flow value is 100%.

[0052] Step 306, when the flow meter fault detection information shows that there is no fault, obtain the second flow meter reading when the flow meter is deployed on the target water purification equipment, and perform fault detection on the target water purification equipment according to the operating state of the target water purification equipment when the second flow meter reading corresponds to the reading, to obtain equipment fault detection information.

[0053] Optionally, the method also includes: when the flow meter fault detection information includes a flow meter fault detection label, if the flow meter fault detection label includes a fault non-existence label, determining the flow meter fault detection information as no fault exists; when the flow meter fault detection information includes a flow meter fault risk value, if the flow meter fault risk value is lower than a preset risk threshold, determining the flow meter fault detection information as no fault exists, wherein the preset risk threshold can be set by the user as needed, or can be an empirical value.

[0054] Exemplarily, obtaining a second flow meter reading when the flow meter is deployed in the target water purification equipment includes: obtaining a second pulse reading, a second electrical parameter reading, or a second flow reading when the flow meter is deployed in the target water purification equipment.

[0055] Exemplarily, according to the operating state of the target water purification equipment when the second flow meter reading corresponds to the reading, fault detection is performed on the target water purification equipment to obtain equipment fault detection information, including: converting the second flow meter reading into a second flow value, and according to the second flow value and the operating state of the target water purification equipment when the second flow meter reading corresponds to the reading, fault detection is performed on the target water purification equipment to obtain equipment fault detection information.

[0056] Optionally, the specific implementation of converting the second flow meter reading into the second flow value may refer to the specific implementation content of the above-mentioned step of converting the first flow meter reading into the first flow value, which will not be described in detail here.

[0057] In this embodiment, a first flow meter reading of a flow meter deployed on a non-faulty water purification device is obtained; based on the first flow meter reading, an operating fault of the flow meter is detected to obtain flow meter fault detection information of the flow meter; when the flow meter fault detection information shows that there is no fault, a second flow meter reading when the flow meter is deployed on the target water purification device is obtained, and based on the operating state of the target water purification device when the second flow meter reading corresponds to the reading, a fault detection is performed on the target water purification device to obtain device fault detection information. When the flow meter fault detection information is ensured to show that there is no fault, that is, when the second flow meter reading when the flow meter is deployed on the target water purification device is ensured to be accurate, the second flow meter reading is used as a basis for corresponding fault detection of the target water purification device. Considering that when the flow meter fails, the risk of low accuracy of water purification device fault detection is brought about when the second flow meter reading is used as the basis for fault detection of the target water purification device. Therefore, the accuracy of water purification device fault detection is improved.

[0058] In one embodiment, Figure 4 As shown, steps of a flow meter fault detection method are provided, in which a first flow meter reading includes a plurality of first flow meter sub-readings respectively read at a plurality of time points; Figure 3 In step 304, the operation fault of the flow meter is detected according to the first flow meter reading to obtain flow meter fault detection information of the flow meter, including:

[0059] Step 402, obtaining a first flow range when the water purification device is not in failure and is in operation.

[0060] Exemplarily, step 402 includes: obtaining the first flow range when a non-faulty water purification device is in operation as set by the user as needed; or, obtaining the first usage flow rate of a non-faulty water purification device during use, and generating the first flow range when the non-faulty water purification device is in operation based on the first usage flow rate; or, obtaining first device information of a non-faulty water purification device, and generating the first flow range when the non-faulty water purification device is in operation based on the device information.

[0061] Furthermore, based on the first usage flow, a first flow range when the water purification device is not faulty is generated, including: the first usage flow includes the first usage sub-flows at multiple time points, and the first flow range when the water purification device is not faulty is generated according to the flow distribution corresponding to the first usage sub-flows at multiple time points. Specifically, it can be to generate the flow range corresponding to the water purification device without fault according to the minimum flow value and the maximum flow value in the first usage sub-flows at multiple time points (determine the minimum flow value as the minimum value in the first flow range, and determine the maximum flow value as the maximum value in the first flow range). It can also be to generate the first flow range when the water purification device is not faulty according to the sum and difference between the average flow value and the average flow difference in the first usage sub-flows at multiple time points (determine the sum of the flow average value and the flow average difference as the maximum value in the first flow range, and determine the difference between the flow average value and the flow average difference as the minimum value in the first flow range).

[0062] In this way, a variety of ways of generating the first flow range are provided, ensuring that the generated flow range can match the flow rate used during normal use of the water purification device.

[0063] The device information involved in the full text (including the first device information mentioned above and the second device information mentioned below) includes at least one of device component information, device usage information and device processing information.

[0064] As one embodiment, based on the first equipment information, a first flow range when a non-faulty water purification device is in operation is generated, including: based on the first equipment information, evaluating the water purification capacity of the non-faulty water purification device to obtain water purification capacity evaluation information of the non-faulty water purification device; based on the water purification capacity evaluation information of the non-faulty water purification device, generating the first flow range when the non-faulty water purification device is in operation.

[0065] Among them, the equipment component information includes at least one of the component model of the water purification components constituting the corresponding water purification equipment (when the equipment information is the first equipment information, the corresponding water purification equipment is a non-faulty water purification equipment, and when the equipment information is the second equipment information, the corresponding water purification equipment is the target water purification equipment) and the component depreciation rate of the water purification components constituting the corresponding water purification equipment, the equipment usage information includes at least one of the equipment usage time, the equipment usage depreciation rate and the water quality of the equipment inlet water, and the equipment processing information includes the equipment processing flow information. The better the component quality of the water purification components represented by the component models of the water purification components constituting the corresponding water purification equipment, the stronger the water purification capacity represented by the water purification capacity assessment information obtained by evaluation; the lower the component depreciation rate of the water purification components constituting the corresponding water purification equipment, the stronger the water purification capacity represented by the water purification capacity assessment information obtained by evaluation; the shorter the equipment is used, the stronger the water purification capacity represented by the water purification capacity assessment information obtained by evaluation; the lower the equipment use depreciation rate, the stronger the water purification capacity represented by the water purification capacity assessment information obtained by evaluation; the better the water quality of the inlet water used by the equipment, the stronger the water purification capacity represented by the water purification capacity assessment information obtained by evaluation; the larger the processing flow value represented by the equipment processing flow information, the stronger the water purification capacity represented by the water purification capacity assessment information obtained by evaluation.

[0066] In this way, the influence of the equipment component information, equipment usage information and equipment processing information on the water purification capacity of the corresponding water purification equipment is taken into consideration, so that the water purification capacity evaluation information obtained by evaluation is more accurate.

[0067] The stronger the water purification capacity represented by the water purification capacity evaluation information is, the higher the flow critical value (maximum value or minimum value in the flow range) generated in the first flow range is.

[0068] In this way, considering that the stronger the water purification capacity of the non-faulty water purification equipment is, the greater the flow rate of water that can be purified by the water purification equipment per unit time is, therefore, the flow critical value in the generated first flow range is higher, so that the first flow range matches the water purification capacity of the non-faulty water purification equipment, thereby improving the generation accuracy of the first flow range.

[0069] Step 404, when there are flow values ​​corresponding to multiple first target sub-readings among multiple first flow meter sub-readings that are outside the first flow range, and the flow duration corresponding to the multiple first target sub-readings is greater than the first preset duration threshold, determine that the flow meter fault detection information of the flow meter is faulty.

[0070] Among them, the first preset time threshold can be set by the user as needed, and can also be determined according to the water purification status corresponding to the non-faulty water purification equipment, and there is no restriction here.

[0071] The flow duration corresponding to the plurality of first target sub-readings is the time difference between the latest reading time and the earliest reading time corresponding to the plurality of first target sub-readings.

[0072] It is understandable that during the use of a non-faulty water purification device, there may be abnormal water purification conditions such as water pressure fluctuations, water outages, water purification device drainage, and water purification device self-cleaning. At this time, the first flow meter reading collected by the flow meter deployed in the non-faulty water purification device is abnormal in itself, and does not mean that the flow meter must be faulty. If the instantaneous first flow meter sub-reading is directly used as the basis for judging whether the flow meter is faulty, and the instantaneous first flow meter sub-reading is under the abnormal water purification condition of the non-faulty water purification device, it is easy to misjudge the flow meter failure, resulting in low accuracy in flow meter failure judgment.

[0073] As an embodiment, the method also includes: selecting a first maximum time duration from at least one of the water pressure fluctuation time duration, water outage time duration, drainage time duration and self-cleaning time duration corresponding to the non-faulty water purification equipment, and determining a first preset time duration threshold value based on the first maximum time duration. Specifically, the first maximum time duration may be determined as the first preset time duration threshold value, or the first preset time duration threshold value may be set to be greater than the first maximum time duration.

[0074] In this way, taking into account the impact of abnormal water purification conditions such as water pressure fluctuations, water outages, water purification equipment drainage, and water purification equipment self-cleaning during the use of a non-faulty water purification equipment on the misjudgment of a flow meter failure, by adding a first preset time threshold that is the same as the maximum duration of the above-mentioned abnormal water purification conditions, when the corresponding flow duration is greater than the first preset time threshold, it is determined that the first flow meter reading of the flow meter is not affected by the abnormal water purification conditions of the water purification equipment, thereby improving the accuracy of the flow meter fault judgment.

[0075] Optionally, the method also includes: when there are no multiple first target sub-readings among the multiple first flow meter readings, or when there are multiple first target sub-readings among the multiple first flow meter readings, and the flow durations corresponding to the multiple first target sub-readings are all no greater than a first preset duration threshold, determining the flow meter fault detection information of the flow meter as no fault exists.

[0076] In this way, when there are no multiple first target sub-readings among multiple first flow meter readings, it means that the non-faulty water purification equipment does not have the above-mentioned abnormal water purification condition. Therefore, the multiple first flow meter readings will not be affected by the above-mentioned abnormal water purification condition of the non-faulty water purification equipment. At this time, the multiple first flow meter readings match the flow rate of the non-faulty water purification equipment during normal use, so it is determined that the flow meter has no fault; when there are multiple first target sub-readings among multiple first flow meter readings, it means that the non-faulty water purification equipment may have the above-mentioned abnormal water purification condition, and when the flow duration corresponding to the multiple first target sub-readings is not greater than the first preset duration threshold, it means that the multiple first target sub-readings are generated after being affected by the abnormal water purification condition of the non-faulty water purification equipment. Then, even if the multiple first target sub-readings do not match the flow rate of the non-faulty water purification equipment during normal use, their duration is short, so it can be determined that the flow meter has no fault; in summary, the detection accuracy of the flow meter fault is improved.

[0077] In this embodiment, by obtaining the first flow range when the non-faulty water purification equipment is running; when there are multiple first target sub-readings among multiple first flow meter sub-readings whose corresponding flow values ​​are outside the first flow range, and the flow duration corresponding to the multiple first target sub-readings is greater than the first preset time threshold, the flow meter fault detection information of the flow meter is determined to be a fault. When there are multiple first target sub-readings among multiple first flow meter sub-readings whose corresponding flow values ​​are outside the first flow range, and the flow duration corresponding to the multiple first target sub-readings is greater than the first preset time threshold, it means that the multiple first target sub-readings are not affected by the water purification conditions of the abnormal use of the non-faulty water purification equipment, that is, the multiple first target sub-readings at this time can characterize that the flow meter readings do not match the flow during normal use of the non-faulty water purification equipment. Therefore, it is determined that the flow meter has a fault, thereby improving the fault detection accuracy of the flow meter.

[0078] In one embodiment, Figure 5 As shown, steps of a method for detecting faults in a water purification device are provided, in which the second flow meter reading includes a plurality of second flow meter sub-readings respectively read at a plurality of time points; Figure 3 In step 306, according to the operating state of the target water purification equipment when the second flow meter reading corresponds to the reading, the target water purification equipment is fault-detected to obtain equipment fault detection information, including:

[0079] Step 502: Obtain a second flow range when the target water purification device is operating in an operating state corresponding to a second flow meter reading.

[0080] Among them, the operating state corresponding to the second flow meter reading is the operating state of the target water purification equipment when the second flow meter reading is read, and the operating state corresponding to the second flow meter reading includes at least one of a water purification operating state and a standby operating state.

[0081] Exemplarily, step 502 includes: when the operating state corresponding to the second flow meter reading of the flow meter includes a water purification operating state, obtaining a first flow sub-range when the target water purification equipment is operating in the water purification state, and determining the first flow sub-range as the second flow range; when the operating state corresponding to the second flow meter reading of the flow meter includes a standby operating state, obtaining a second flow sub-range when the target water purification equipment is operating in the standby operating state, and determining the second flow sub-range as the second flow range; when the operating state corresponding to the second flow meter reading of the flow meter includes a water purification operating state and a standby operating state, obtaining the first flow sub-range when the target water purification equipment is operating in the water purification state, and obtaining the second flow sub-range when the target water purification equipment is operating in the standby operating state, and jointly determining the first flow sub-range and the second flow sub-range as the second flow range.

[0082] Furthermore, obtaining a first flow sub-range when the target water purification equipment is operating in a water purification state includes: obtaining second equipment information of the target water purification equipment, evaluating the water purification capacity of the target water purification equipment based on the second equipment information, and obtaining water purification capacity evaluation information of the target water purification equipment; generating a first flow sub-range when the target water purification equipment is operating in a water purification state based on the water purification capacity evaluation information of the target water purification equipment.

[0083] Optionally, based on the second equipment information, the water purification capacity of the target water purification equipment is evaluated to obtain the water purification capacity evaluation information of the target water purification equipment; based on the water purification capacity evaluation information of the target water purification equipment, a specific implementation method of generating the first flow sub-range when the target water purification equipment is operating in a water purification state can refer to the above-mentioned step of evaluating the water purification capacity of a non-faulty water purification equipment based on the first equipment information to obtain the water purification capacity evaluation information of a non-faulty water purification equipment; and generating the first flow range when the non-faulty water purification equipment is operating based on the water purification capacity evaluation information of the non-faulty water purification equipment. The specific implementation content of the step will not be repeated here.

[0084] The highest value corresponding to the second flow sub-range is lower than the lowest value corresponding to the first flow sub-range.

[0085] It is understandable that when the target water purification equipment is operating in standby mode, no water will enter the target water purification equipment. Therefore, the flow rate of the water channel in the target water purification equipment should be small. Therefore, the maximum value corresponding to the second flow sub-range is set lower than the minimum value corresponding to the first flow sub-range.

[0086] Step 504, when there are multiple second target sub-readings among the multiple second flow meter sub-readings whose flow values ​​correspond to the multiple second target sub-readings are outside the second flow range, and the flow duration corresponding to the multiple second target sub-readings is greater than the second preset duration threshold, it is determined that the equipment fault detection information of the target water purification equipment includes a switch valve fault.

[0087] The plurality of second flow meter sub-readings include at least one of a plurality of third flow sub-readings corresponding to a water purification operation state and a plurality of fourth flow sub-readings corresponding to a standby operation state.

[0088] The second preset time threshold includes at least one of a first preset sub-time threshold corresponding to the first traffic sub-range and a second preset sub-time threshold corresponding to the second traffic sub-range.

[0089] As an embodiment, the method also includes: in a case where multiple second flow meter sub-readings include multiple third flow sub-readings whose corresponding operating states are water purification operating states, if there are multiple third target sub-readings among the multiple third flow sub-readings whose corresponding flow values ​​are outside the first flow sub-range, and the flow duration corresponding to the multiple third target sub-readings is greater than the first preset sub-time threshold, then it is determined that there are multiple second target sub-readings among the multiple second flow meter sub-readings whose corresponding flow values ​​are outside the second flow range, and the flow duration corresponding to the multiple second target sub-readings is greater than the second preset time threshold.

[0090] As another embodiment, the method also includes: in a case where multiple second flow meter sub-readings include multiple fourth flow sub-readings whose corresponding operating state is a standby operating state, if there are multiple fourth target sub-readings among the multiple fourth flow sub-readings whose corresponding flow values ​​are outside the second flow sub-range, and the flow duration corresponding to the multiple fourth target sub-readings is greater than the second preset sub-time threshold, then it is determined that there are multiple second target sub-readings among the multiple second flow meter sub-readings whose corresponding flow values ​​are outside the second flow range, and the flow duration corresponding to the multiple second target sub-readings is greater than the second preset time threshold.

[0091] Optionally, the method also includes: selecting a second maximum duration from at least one of the water pressure fluctuation duration and the water outage duration corresponding to the target water purification equipment, and determining a first preset sub-time threshold in the second preset time threshold based on the second maximum time. Specifically, the second maximum duration may be determined as the first preset sub-time threshold in the second preset time threshold, or the first preset sub-time threshold in the second preset time threshold may be set to be greater than the second maximum duration.

[0092] In this way, taking into account the impact of abnormal water purification conditions such as water pressure fluctuations and water outages on the misjudgment of the target water purification equipment failure when the target water purification equipment is running in the water purification operation state, by adding a first preset sub-time threshold that is the same as or longer than the maximum duration of the water purification condition with the above-mentioned abnormal water purification use, when the corresponding flow duration is greater than the first preset sub-time threshold, it is determined that the third flow sub-reading of the flow meter is not affected by the abnormal water purification condition of the water purification equipment, thereby improving the accuracy of water purification equipment failure judgment.

[0093] It is understandable that when the target water purification equipment is operating in the standby operation state, the target water purification equipment may perform equipment cleaning processes such as equipment drainage or equipment self-cleaning. At this time, the second flow meter reading collected by the flow meter deployed on the target water purification equipment is likely to not match the standby operation state, which does not mean that the target water purification equipment must have a fault. If the instantaneous fourth flow meter sub-reading is directly used as the basis for judging whether the target water purification equipment is faulty, and the instantaneous fourth flow meter sub-reading is collected during the equipment cleaning process of the target water purification equipment, it is easy to misjudge the fault of the target water purification equipment, resulting in low accuracy in the judgment of the fault of the target water purification equipment.

[0094] Optionally, the method further includes: obtaining the time required for cleaning the target water purification equipment; and determining a second preset sub-time threshold in the second preset time threshold according to the time required for cleaning the equipment.

[0095] Furthermore, obtaining the time required for cleaning the target water purification equipment includes: selecting a third maximum time from at least one of the drainage time and the equipment self-cleaning time of the target water purification equipment, and determining the time required for cleaning the equipment according to the third maximum time. Specifically, the third maximum time may be determined as the time required for cleaning the equipment, or the time required for cleaning the equipment may be set to be greater than the third maximum time.

[0096] As one embodiment, based on the time required for equipment cleaning, a second preset sub-time threshold in the second preset time threshold is determined, including: determining the time required for equipment cleaning as the second preset sub-time threshold in the second preset time threshold, or setting the second preset sub-time threshold in the second preset time threshold to be greater than the time required for equipment cleaning.

[0097] In this way, taking into account that when the target water purification equipment is running in the standby operation state, there may be equipment cleaning processes such as water purification equipment drainage and water purification equipment self-cleaning, which may affect the misjudgment of the target water purification equipment failure. By adding a second preset sub-time threshold that is the same as or longer than the maximum duration of the above-mentioned equipment cleaning process, when the corresponding flow duration is greater than the second preset sub-time threshold, it is determined that the second target sub-reading of the flow meter is not affected by the equipment cleaning process of the water purification equipment, thereby improving the accuracy of the target water purification equipment failure judgment.

[0098] Optionally, the method also includes: when there are no multiple second target sub-readings among the multiple second flow meter sub-readings, or when there are multiple second target sub-readings among the multiple second flow meter sub-readings, and the flow durations corresponding to the multiple second target sub-readings are all no greater than a second preset duration threshold, then determining that the equipment fault detection information of the target water purification equipment includes that there is no fault in the switch valve.

[0099] In this way, when there are no multiple second target sub-readings among the multiple second flow meter sub-readings, it means that the target water purification equipment does not have the above-mentioned abnormal water purification condition. Therefore, the multiple second flow meter sub-readings will not be affected by the above-mentioned abnormal water purification condition of the target water purification equipment. At this time, the multiple second flow meter sub-readings match the flow rate of the target water purification equipment during normal use. Therefore, it is determined that the switch valve of the target water purification equipment has no fault. When there are multiple second target sub-readings among the multiple second flow meter sub-readings, it means that the target water purification equipment may have the above-mentioned abnormal water purification condition. When the flow duration corresponding to the multiple second target sub-readings is not greater than the preset duration threshold, it means that the multiple second target sub-readings are generated after being affected by the abnormal water purification condition of the target water purification equipment. Then, even if the multiple second target sub-readings do not match the flow rate of the target water purification equipment during normal use, their duration is short. Therefore, it can be determined that the switch valve of the target water purification equipment has no fault. In summary, the detection accuracy of the target water purification equipment fault is improved.

[0100] As an embodiment, the method also includes: in a case where multiple second flow meter sub-readings only include multiple third flow sub-readings whose corresponding operating state is a water purification operating state, if multiple third flow sub-readings do not have multiple third target sub-readings, then determining that multiple second flow meter sub-readings do not have multiple second target sub-readings; or, in a case where multiple second flow meter sub-readings only include multiple fourth flow sub-readings whose corresponding operating state is a standby operating state, if multiple fourth flow sub-readings do not have multiple fourth target sub-readings, then determining that multiple second flow meter sub-readings do not have multiple second target sub-readings; or, in a case where multiple second flow meter sub-readings include multiple third flow sub-readings whose corresponding operating state is a water purification operating state and multiple fourth flow sub-readings whose corresponding operating state is a standby operating state, if multiple third flow sub-readings do not have multiple third target sub-readings and multiple fourth flow sub-readings do not have multiple fourth target sub-readings, then determining that multiple second flow meter sub-readings do not have multiple second target sub-readings.

[0101] As another embodiment, the method further includes: in a case where the multiple second flow meter sub-readings only include multiple third flow sub-readings whose corresponding operating state is a water purification operating state, if the multiple third flow sub-readings have multiple third target sub-readings, and the flow durations corresponding to the multiple third target sub-readings are not greater than the first preset sub-time threshold, then determining that the multiple second flow meter sub-readings have multiple second target sub-readings, and the flow durations corresponding to the multiple second target sub-readings are not greater than the second preset time threshold; or, in a case where the multiple second flow meter sub-readings only include multiple fourth flow sub-readings whose corresponding operating state is a standby operating state, if the multiple fourth flow sub-readings have multiple fourth target sub-readings, and the flow durations corresponding to the multiple fourth target sub-readings are not greater than the second preset sub-time threshold, It is determined that there are multiple second target sub-readings among the multiple second flow meter sub-readings, and the flow durations corresponding to the multiple second target sub-readings are not greater than the second preset duration threshold; or, when the multiple second flow meter sub-readings include multiple third flow sub-readings whose corresponding operating states are water purification operating states and multiple fourth flow sub-readings whose corresponding operating states are standby operating states, if the flow durations corresponding to multiple third target sub-readings in the multiple third flow sub-readings are not greater than the first preset sub-time threshold, and the flow durations corresponding to multiple fourth target sub-readings in the multiple fourth flow sub-readings are not greater than the second preset sub-time threshold, it is determined that there are multiple second target sub-readings among the multiple second flow meter sub-readings, and the flow durations corresponding to the multiple second target sub-readings are not greater than the second preset time threshold.

[0102] In this way, it is considered that the second flow meter sub-readings include determination conditions corresponding to different types of readings.

[0103] Optionally, the method also includes: obtaining at least one pressure switch signal of a pressure switch deployed in the target water purification equipment; if it is detected that the cumulative number of signals of at least one pressure switch signal within a second preset time threshold is greater than a preset number threshold, then determining that the equipment fault detection information of the target water purification equipment includes a pressure switch fault.

[0104] Optionally, the method also includes: if the cumulative number of detected pressure switch signals is not greater than a preset number threshold, or the signal duration corresponding to the pressure switch signal is greater than a second preset duration threshold, then determining that the equipment fault detection information of the target water purification equipment includes that the pressure switch does not have a fault.

[0105] In which, when the second preset duration threshold includes the first preset sub-duration threshold and the second preset sub-duration threshold, the longer threshold of the first preset sub-duration threshold and the second preset sub-duration threshold is used as the detection duration threshold of the pressure switch signal in the above steps.

[0106] In this way, it is ensured that the pressure switch signal is not affected by the equipment cleaning process of the target water purification equipment, thereby improving the accuracy of fault judgment of the target water purification equipment.

[0107] In the present embodiment, the second flow range of the target water purification equipment when it is operating in the operating state corresponding to the second flow meter reading is obtained; when there are flow values ​​corresponding to multiple second target sub-readings among multiple second flow meter sub-readings that are outside the second flow range, and the flow duration corresponding to the multiple second target sub-readings is greater than the second preset time threshold, it is determined that the equipment fault detection information of the target water purification equipment includes a switch valve fault. When there are flow values ​​corresponding to multiple second target sub-readings among multiple second flow meter sub-readings that are outside the second flow range, and the flow duration corresponding to the multiple second target sub-readings is greater than the second preset time threshold, it means that the multiple second target sub-readings are not affected by the water purification condition of abnormal use of the target water purification equipment, that is, the multiple second target sub-readings at this time can characterize that the flow meter readings do not match the flow when the target water purification equipment is operating in the corresponding operating state, so it is determined that the switch valve of the target water purification equipment is faulty, thereby improving the accuracy of water purification equipment fault detection.

[0108] As a more detailed embodiment, a first flow meter reading of a flow meter deployed on a non-faulty water purification device is obtained; first device information of the non-faulty water purification device is obtained, wherein the first device information includes at least one of device component information, device usage information and device processing information; based on the device information, the water purification capacity of the water purification device is evaluated to obtain water purification capacity evaluation information of the water purification device; based on the water purification capacity evaluation information, a first flow range when the non-faulty water purification device is in operation is generated; when there are multiple first target sub-readings among multiple first flow meter sub-readings whose corresponding flow values ​​are outside the first flow range, and the flow duration corresponding to the multiple first target sub-readings is greater than a first preset duration threshold, the flow meter fault detection information of the flow meter is determined to be a fault.

[0109] Furthermore, when the flow meter fault detection information indicates that there is no fault, a second flow meter reading is obtained when the flow meter is deployed on the target water purification equipment, and a second flow range when the target water purification equipment is operating in the operating state corresponding to the second flow meter reading is obtained; the time required for equipment cleaning of the target water purification equipment is obtained; based on the time required for equipment cleaning, a second preset time threshold is determined; when there are multiple second target sub-readings among multiple second flow meter sub-readings whose flow values ​​are outside the second flow range, and the flow duration corresponding to the multiple second target sub-readings is greater than the second preset time threshold, it is determined that the equipment fault detection information of the target water purification equipment includes a fault in the switch valve; at least one pressure switch signal of the pressure switch deployed on the target water purification equipment is obtained; if it is detected that the cumulative number of signals of at least one pressure switch signal within the second preset time threshold is greater than the preset number threshold, it is determined that the equipment fault detection information of the target water purification equipment includes a fault in the pressure switch.

[0110] In this way, by ensuring that the flow meter fault detection information is that there is no fault, that is, ensuring that the second flow meter reading when the flow meter is deployed in the target water purification equipment is accurate, the second flow meter reading is used as the basis for the corresponding fault detection of the target water purification equipment. Taking into account the risk of low accuracy of water purification equipment fault detection when the flow meter fails and the second flow meter reading is used as the basis for target water purification equipment fault detection, the accuracy of water purification equipment fault detection is improved.

[0111] Further, when, among multiple first flow meter sub-readings, there are multiple first target sub-readings whose corresponding flow values ​​are outside the first flow range, and the flow duration corresponding to the multiple first target sub-readings is greater than the first preset time threshold, it means that the multiple first target sub-readings are not affected by the water purification condition of the abnormal use of the non-faulty water purification equipment, that is, the multiple first target sub-readings at this time can characterize that the flow meter readings do not match the flow during normal use of the non-faulty water purification equipment, so it is determined that the flow meter has a fault, which improves the accuracy of flow meter fault detection; and, when, among multiple second flow meter sub-readings, there are multiple second target sub-readings whose corresponding flow values ​​are outside the second flow range, and the flow duration corresponding to the multiple second target sub-readings is greater than the second preset time threshold, it means that the multiple second target sub-readings are not affected by the water purification condition of the abnormal use of the target water purification equipment, that is, the multiple second target sub-readings at this time can characterize that the flow meter readings do not match the flow during operation of the corresponding operating state of the target water purification equipment, so it is determined that the switch valve of the target water purification equipment has a fault, which improves the accuracy of water purification equipment fault detection.

[0112] It should be understood that, although the steps in the flowcharts involved in the above embodiments are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows.
