Description

Technical Field

[0001] The present application relates to the field of flow detection technology, and in particular to a flow monitoring method, system, intelligent terminal and storage medium. Background Art

[0002] A flow meter is an instrument used to measure the flow of a fluid through a pipe or other equipment. It is widely used in many fields such as industrial production, energy management, and environmental monitoring.

[0003] In the related art, when flow detection is required, the staff will install the flow meter at the detection position corresponding to the pipeline, and in the subsequent period of time, the operator will read the flow meter reading and inspect the flow meter at regular intervals to ensure that the flow meter can detect the flow of the pipeline normally and accurately.

[0004] With respect to the above-mentioned related technologies, operators read the flow meter readings and inspect the flow meter at regular intervals. Due to the quality requirements of the flow meter itself, the probability of failure of the flow meter is not high. Therefore, most of the flow meters inspected by operators are normal, resulting in a waste of inspection time on normal flow meters, resulting in low inspection accuracy of the flow meter, and there is still room for improvement. Summary of the invention

[0005] In order to improve the maintenance accuracy of the flow meter, the present application provides a flow monitoring method, system, intelligent terminal and storage medium.

[0006] In a first aspect, the present application provides a flow monitoring method, which adopts the following technical solution: A flow monitoring method, comprising: Obtaining a start trigger signal of a preset working flow meter; the working flow meter is characterized as a flow meter for detecting pipeline flow; According to the start trigger signal, a preset flow meter monitor is controlled to monitor the state of the working flow meter to generate monitoring state data; the flow meter monitor is characterized as a flow meter that monitors the working state of the working flow meter; Determine whether the monitoring status data meets the requirements of the preset normal status type; If it meets the requirements, the flow meter reading of the working flow meter is obtained, and the flow meter reading is uploaded to the preset management platform; If it does not meet the requirements, a prompt will be given according to the preset flow meter abnormal information.

[0007] By adopting the above technical solution, after the working flow meter starts working, the flow meter monitor is controlled to monitor the status of the working flow meter. When it is determined that the monitoring status data conforms to the normal status type, it indicates that the working flow meter is normal. Therefore, the flow meter reading is uploaded to the management platform. When it is determined that the monitoring status data does not conform to the normal status type, it indicates that the working flow meter is abnormal. Therefore, prompts are given based on the abnormal information of the flow meter, so that personnel can repair the abnormal working flow meter without wasting time on the normal flow meter, thereby improving the maintenance accuracy of the flow meter.

[0008] Optionally, the step of controlling a preset flow meter monitor to monitor the status of the working flow meter according to the start trigger signal to generate monitoring status data includes: Obtain the calibration interval of the flow meter monitor in real time based on the start trigger signal; Determine whether the calibration interval meets the preset benchmark calibration time requirements; If it does not meet the requirements, the flow meter monitor is calibrated according to the preset calibration trigger signal to generate calibration result data; When the verification result data meets the preset normal result data requirements, the verification interval time is reset, and the flow meter monitor is controlled to monitor the working flow meter to generate monitoring status data; If it meets the requirements, the calibration interval of the flow meter monitor is continuously obtained for cyclic judgment, and the flow meter monitor is controlled to monitor the status of the working flow meter to generate monitoring status data.

[0009] By adopting the above technical solution, the calibration interval of the flow meter monitor is detected. After determining that the calibration interval exceeds the benchmark calibration time, the flow meter monitor needs to be calibrated to ensure that the flow meter monitor is normal. Only then can the flow meter monitor be used to monitor the working flow meter, thereby ensuring the monitoring accuracy of the working flow meter.

[0010] Optionally, the step of controlling the flow meter monitor to perform status monitoring on the working flow meter to generate monitoring status data includes: Obtain monitoring change indication of the flow meter monitor and flow meter cumulative amount of the working flow meter; Determine whether the monitored change indication meets the preset normal change indication requirements; If it meets the requirements of normal change indication, then determine whether the flow meter cumulative amount meets the preset requirements of existence cumulative amount; If the requirement of existence of cumulative amount is met, the preset normal monitoring data is defined as monitoring status data; If the requirement of the existence of cumulative amount is not met, the flow meter monitor is controlled to perform depth monitoring on the working flow meter according to the preset depth monitoring trigger signal; If the requirements for normal change indication are not met, the monitoring status data is determined according to the preset re-judgment trigger signal.

[0011] By adopting the above technical solution, when it is determined that the monitoring change indication meets the requirements of the normal change indication, it indicates that there is water flow in the pipeline. If the flow meter cumulative amount of the working flow meter meets the requirements of the existence of the cumulative amount, it indicates that the working flow meter is normal. Therefore, the normal monitoring data is determined to be the monitoring status data. When it does not meet the requirements, it indicates that the working flow meter may be abnormal. Therefore, the flow meter monitor is controlled according to the depth monitoring trigger signal to perform deep monitoring of the working flow meter, thereby improving the accuracy of monitoring the working flow meter.

[0012] Optionally, the step of determining the monitoring status data according to a preset re-determination trigger signal includes: Determine whether the flow meter cumulative amount meets the preset requirement of the cumulative amount; If the requirement of the existence of cumulative amount is not met, the preset monitoring normal data is defined as monitoring status data; If the requirement of the accumulated amount is met, the flow meter monitor is controlled to perform depth monitoring on the working flow meter according to the preset depth monitoring trigger signal.

[0013] By adopting the above technical solution, when the monitoring change indication does not meet the requirements of the normal change indication, it indicates that there is no water flow in the pipeline. If the flow meter cumulative amount does not meet the requirements of the existence of the cumulative amount, it indicates that the working flow meter is normal. Therefore, the normal monitoring data is determined to be the monitoring status data. If it meets the requirements, it indicates that the working flow meter may be abnormal. Therefore, the flow meter monitor is controlled according to the depth monitoring trigger signal to perform deep monitoring of the working flow meter, thereby improving the accuracy of monitoring the working flow meter.

[0014] Optionally, the step of controlling the flow meter monitor to perform depth monitoring on the working flow meter according to a preset depth monitoring trigger signal includes: Control the flow meter monitor to monitor the working flow meter according to the preset repeated monitoring times, and obtain the normal monitoring times and the abnormal monitoring times; Determine whether the number of normal monitoring times is greater or less than the number of abnormal monitoring times; If it is greater, the preset normal monitoring data is defined as monitoring status data; If it is less than, the preset monitoring abnormal data is defined as the monitoring status data.

[0015] By adopting the above technical solution, the flow meter monitor is controlled to monitor the working flow meter by repeating the monitoring times, so as to obtain the normal monitoring times and the abnormal monitoring times. When it is determined that the normal monitoring times are greater than the abnormal monitoring times, it indicates that the working flow meter is normal, and thus the normal monitoring data is defined as the monitoring status data. When it is determined that the normal monitoring times are less than the abnormal monitoring times, it indicates that the working flow meter is abnormal, and thus the abnormal monitoring data is defined as the monitoring status data, thereby improving the accuracy of monitoring the working flow meter.

[0016] Optionally, the step of calibrating the flow meter monitor according to a preset calibration trigger signal to generate calibration result data includes: Isolating the flow meter monitor from the working flow meter according to a preset flow meter isolation trigger signal; Control the preset water outlet device to discharge water to the flow meter monitor according to the preset benchmark verification flow, and obtain the detection verification flow of the flow meter monitor; Determine whether the detection verification flow rate meets the requirements of the benchmark verification flow rate; If it is in compliance, the preset normal verification data is defined as the verification result data; If it does not meet the requirements, the preset verification abnormality data is defined as the verification result data.

[0017] By adopting the above technical scheme, the water outlet device is controlled to discharge water to the flow meter monitor according to the benchmark verification flow, and the detection verification flow is collected. When it is determined that the detection verification flow meets the requirements of the benchmark verification flow, it indicates that the flow meter monitor is normal, and the normal verification data is defined as the verification result data. If it does not meet the requirements, it indicates that the flow meter monitor is abnormal, and the abnormal verification data is defined as the verification result data, thereby improving the verification accuracy of the flow meter monitor.

[0018] Optionally, the step of isolating the flow meter monitor from the working flow meter according to a preset flow meter isolation trigger signal includes: Controlling the preset water intake valve to close so as to disconnect the preset water intake pipeline and the preset water outlet pipeline; the water intake pipeline is characterized as a pipeline for taking water from the source, the working flow meter is installed on the water intake pipeline, the water outlet pipeline is characterized as a pipeline for water to flow out of the water intake pipeline, and the flow meter monitor is installed on the water outlet pipeline; Controlling the preset diverting valve to open so as to control the water intake pipeline to be connected with the preset diverting pipeline; The preset water inlet valve is controlled to open to control the connection between the water outlet pipe and the preset water inlet pipe to isolate the flow meter monitor and the working flow meter.

[0019] By adopting the above technical solution, the working flow meter and the flow meter monitor are isolated, and then the flow meter monitor is calibrated. On the one hand, it prevents the water flow in the pipeline from affecting the calibration, and on the other hand, it prevents the calibration from affecting normal water use, thereby improving the convenience of calibration.

[0020] In a second aspect, the present application provides a flow monitoring system, which adopts the following technical solution: A flow monitoring system, comprising: An acquisition module, used for acquiring an opening trigger signal and a flow meter indication; A memory, used to store a program of a flow monitoring method as described in any one of the above items; The program in the processor memory can be loaded and executed by the processor to implement a flow monitoring method as described in any one of the above items.

[0021] By adopting the above technical solution, the control processor loads and executes a program of a flow monitoring method stored in the memory, so that the acquisition module obtains a series of data related to flow monitoring. After the working flow meter starts working, the flow meter monitor is controlled to monitor the status of the working flow meter. When it is determined that the monitoring status data conforms to the normal status type, it indicates that the working flow meter is normal. Therefore, the flow meter reading is uploaded to the management platform. When it is determined that the monitoring status data does not conform to the normal status type, it indicates that the working flow meter is abnormal. Therefore, a prompt is given according to the abnormal information of the flow meter, so that personnel can repair the abnormal working flow meter without wasting time on the normal flow meter, thereby improving the maintenance accuracy of the flow meter.

[0022] In a third aspect, the present application provides a smart terminal, which adopts the following technical solution: An intelligent terminal comprises a memory and a processor, wherein the memory stores a computer program which can be loaded by the processor and executes a flow monitoring method as described in any one of the above items.

[0023] By adopting the above technical solution, by operating the intelligent terminal, the processor loads and executes a computer program of a flow monitoring method stored in the memory, so that after the working flow meter starts working, the flow meter monitor is controlled to monitor the status of the working flow meter. When it is determined that the monitoring status data conforms to the normal status type, it indicates that the working flow meter is normal, so the flow meter reading is uploaded to the management platform. When it is determined that the monitoring status data does not conform to the normal status type, it indicates that the working flow meter is abnormal, so a prompt is given according to the abnormal information of the flow meter, so that personnel can repair the abnormal working flow meter without wasting time on the normal flow meter, thereby improving the maintenance accuracy of the flow meter.

[0024] In a fourth aspect, the present application provides a computer storage medium capable of storing corresponding programs, which is convenient for improving the maintenance accuracy of the flow meter, and adopts the following technical solutions: A computer-readable storage medium stores a computer program that can be loaded by a processor and execute any of the above-mentioned flow monitoring methods.

[0025] By adopting the above technical solution, a computer program of a flow monitoring method is stored in a computer-readable storage medium, so that the processor loads and executes the computer program in the storage medium, so that after the working flow meter starts working, the flow meter monitor is controlled to monitor the status of the working flow meter. When it is determined that the monitoring status data conforms to the normal status type, it indicates that the working flow meter is normal, so the flow meter reading is uploaded to the management platform. When it is determined that the monitoring status data does not conform to the normal status type, it indicates that the working flow meter is abnormal, so a prompt is given according to the abnormal information of the flow meter, so that personnel can repair the abnormal working flow meter without wasting time on the normal flow meter, thereby improving the maintenance accuracy of the flow meter.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: After the working flow meter starts working, the flow meter monitor is controlled to monitor the working flow meter. When it is determined that the monitoring status data conforms to the normal status type, it indicates that the working flow meter is normal. Therefore, the flow meter reading is uploaded to the management platform. When it is determined that the monitoring status data does not conform to the normal status type, it indicates that the working flow meter is abnormal. Therefore, prompts are given according to the abnormal information of the flow meter, so that personnel can repair the abnormal working flow meter without wasting time on the normal flow meter, thereby improving the repair accuracy of the flow meter; By testing the calibration interval of the flow meter monitor, after determining that the calibration interval exceeds the benchmark calibration time, the flow meter monitor needs to be calibrated to ensure that the flow meter monitor is normal, and then the flow meter monitor is used to monitor the working flow meter, thereby ensuring the monitoring accuracy of the working flow meter; The working flow meter is monitored by controlling the flow meter monitor with repeated monitoring times, so as to obtain the normal monitoring times and the abnormal monitoring times. When it is determined that the normal monitoring times are greater than the abnormal monitoring times, it indicates that the working flow meter is normal. Therefore, the normal monitoring data is defined as the monitoring status data. When it is determined that the normal monitoring times are less than the abnormal monitoring times, it indicates that the working flow meter is abnormal. Therefore, the abnormal monitoring data is defined as the monitoring status data, thereby improving the accuracy of monitoring the working flow meter. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] In order to make the purpose, technical solutions and advantages of this application more clear, the following Figure 1-Figure 8 It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0036] The embodiment of the present application discloses an accurate monitoring method for pipeline flow, and specifically discloses a processing terminal, a working flow meter, a flow meter monitor and a management platform. The processing terminal, the working flow meter, the flow meter monitor and the management platform respectively implement data interaction and control through RS-485 communication. After the processing terminal receives the start trigger signal of the working flow meter, the processing terminal responds to the start trigger signal to control the flow meter monitor to monitor the status of the working flow meter and generate monitoring status data. When the processing terminal determines that the monitoring status data meets the requirements of the normal status type, the processing terminal transmits the flow meter reading to the management platform. When it does not meet the requirements, a prompt is given according to the abnormal information of the flow meter, so that the maintenance personnel can promptly repair the abnormal working flow meter without wasting time on the normal flow meter, thereby improving the maintenance accuracy of the flow meter.

[0037] Reference Figure 1 The present application discloses a flow monitoring method, comprising the following steps: Step S100: obtaining a start trigger signal of a preset working flow meter; the working flow meter is characterized as a flow meter for detecting pipeline flow.

[0038] The working flow meter refers to a flow meter for detecting pipeline flow, and an electromagnetic flow meter is used as an example in the embodiment of the present application. The start trigger signal refers to the trigger data for starting the working flow meter. After the operator starts the working flow meter, the working flow meter sends the start trigger signal to the processing terminal.

[0039] Step S101: controlling a preset flow meter monitor to monitor the status of a working flow meter according to a start trigger signal to generate monitoring status data; the flow meter monitor is characterized as a flow meter that monitors the working status of the working flow meter.

[0040] Among them, after the processing terminal receives the start trigger signal, it indicates that the working flow meter starts to detect the flow of the pipeline. Therefore, the processing terminal controls the flow meter monitor to monitor the working status of the working flow meter and generate monitoring status data, thereby providing data support for subsequent determination of whether the working flow meter is working normally.

[0041] The flow meter monitor refers to a device for monitoring the working state of the working flow meter. In the embodiment of the present application, another flow meter is used to monitor the working flow meter. Figure 8 The flow meter monitor and the working flow meter are installed on the same pipeline and behind the working flow meter. The monitoring status data refers to the working status of the working flow meter, including abnormal status and normal status. The flow meter monitor monitors the working flow meter to obtain the status data. For specific methods, refer to Figure 2 steps.

[0042] Step S102: Determine whether the monitoring status data meets the requirements of the preset normal status type.

[0043] The normal state type refers to the working flow meter being in a normal state, and the requirement of the normal state type refers to the state being consistent with the state corresponding to the normal state type, which are all stored in the processing terminal by the operator.

[0044] The processing terminal determines whether the state corresponding to the monitoring state data is consistent with the state corresponding to the normal state type, thereby determining whether the working state of the working flow meter is normal.

[0045] Step S1021: If it meets the requirements, the flow meter reading of the working flow meter is obtained, and the flow meter reading is uploaded to the preset management platform.

[0046] Among them, if the processing terminal determines that the state corresponding to the monitoring status data is consistent with the state corresponding to the normal state type, it indicates that the working state of the working flow meter is normal. Therefore, the flow meter reading of the working flow meter is detected and the flow meter reading is uploaded to the management platform.

[0047] The flow meter reading refers to the reading of the pipeline flow detected by the working flow meter, which is detected by the working flow meter and sent to the processing terminal. The management platform refers to the platform for statistical display of all flow meter readings in the area.

[0048] Step S1022: If not, prompt according to the preset flow meter abnormal information.

[0049] Among them, if the processing terminal determines that the state corresponding to the monitoring status data is inconsistent with the state corresponding to the normal state type, it indicates that the working state of the working flow meter is abnormal. Therefore, a prompt is given according to the abnormal information of the flow meter, so that the maintenance personnel can repair the abnormal flow meter in time.

[0050] Flow meter abnormality information refers to information that prompts personnel that the flow meter is working abnormally, and is sent from the processing terminal to the operator's smart terminal.

[0051] Reference Figure 2 The steps of controlling a preset flow meter monitor to monitor the working flow meter status according to the start trigger signal to generate monitoring status data include: Step S200: acquiring the calibration interval of the flow meter monitor in real time based on the start trigger signal.

[0052] The calibration interval time refers to the interval time between the current time and the last calibration time of the flow meter monitor, which is measured by a timer and sent to the processing terminal.

[0053] Step S201: Determine whether the verification interval meets the preset reference verification time requirement.

[0054] The reference calibration time refers to the interval time for calibrating the flow meter monitor. The specific value is determined by the operator according to the actual situation. The reference calibration time requirement refers to being less than the reference calibration time.

[0055] The processing terminal determines whether the calibration interval time is less than the reference calibration time, thereby determining whether it is necessary to calibrate the flow meter monitor before monitoring the working flow meter.

[0056] Step S2011: If not, the flow meter monitor is calibrated according to a preset calibration trigger signal to generate calibration result data.

[0057] If the processing terminal determines that the calibration interval is not less than the reference calibration time, it means that the flow meter monitor has been calibrated for a long time since the last calibration. Therefore, it is necessary to calibrate the flow meter monitor according to the calibration trigger signal and generate calibration result data. For specific methods, refer to Figure 6 steps to ensure that the flow meter monitor remains accurate at all times.

[0058] The calibration trigger signal is the trigger signal for starting the calibration of the flow meter monitor, which is stored in the processing terminal by the operator. The calibration result data is the result obtained after the calibration of the flow meter monitor, including normal calibration result and abnormal calibration result. For specific acquisition methods, refer to Figure 6 steps.

[0059] Step S20111: When the verification result data meets the preset requirements of the normal result data, the verification interval is reset, and the flow meter monitor is controlled to monitor the status of the working flow meter to generate monitoring status data.

[0060] The normal result data refers to the data of normal flow meter monitor calibration results, and the requirement of the normal result data is that the results corresponding to the normal result data are consistent, and are all stored in the processing terminal by the operator.

[0061] When the processing terminal determines that the verification result data is consistent with the result corresponding to the normal result data, it indicates that the flow meter monitor is normal, so the verification interval is reset, so as to re-time the verification time of the flow meter monitor, and control the flow meter monitor to monitor the working flow meter to generate monitoring status data. For specific methods, refer to Figure 3 If the verification result data is inconsistent with the result corresponding to the normal result data, the personnel will be prompted to repair the flow meter monitor.

[0062] Step S2012: If it meets the requirements, continue to obtain the verification interval of the flow meter monitor for cyclic judgment, and control the flow meter monitor to monitor the status of the working flow meter to generate monitoring status data.

[0063] If the processing terminal determines that the calibration interval is less than the reference calibration time, it indicates that the flow meter monitor is not required to be calibrated again after a short time since the last calibration. Therefore, the calibration interval of the flow meter monitor is continuously timed, so as to perform a cyclic judgment and control the flow meter monitor to monitor the working flow meter status and generate monitoring status data. For specific methods, refer to Figure 3 steps.

[0064] Reference Figure 3 The steps of controlling the flow meter monitor to monitor the working flow meter and generate monitoring status data include: Step S300: Obtain the monitoring change indication of the flow meter monitor and the flow meter cumulative amount of the working flow meter.

[0065] The monitoring change indication refers to the water flow indication of the water flowing through the pipeline by the flow meter monitor, which is detected by the flow meter monitor and sent to the processing terminal. The flow meter cumulative amount refers to the water flow indication of the water flowing through the pipeline by the working flow meter, which is detected by the working flow meter and sent to the processing terminal.

[0066] Step S301: Determine whether the monitored change indication meets the preset normal change indication requirement.

[0067] The normal variation indication refers to the indication when the flow meter monitor detects the presence of water flow in the pipeline, and the requirement for the normal variation indication refers to the indication existing in the indication corresponding to the normal variation indication.

[0068] The processing terminal determines whether the monitored change indication exists in the indication corresponding to the normal change indication, thereby determining whether there is water flow in the pipeline.

[0069] Step S3011: If the requirement of normal change indication is met, determine whether the flow meter accumulation meets the preset requirement of existence accumulation.

[0070] The existence of accumulated quantity refers to the flow meter indication when the working flow meter detects water flow, and the requirement for the existence of accumulated quantity refers to the existence in the flow meter indication corresponding to the existence of accumulated quantity.

[0071] If the processing terminal determines that the monitored change indication exists in the indication corresponding to the normal change indication, it indicates that there is water flow in the pipeline. At this time, the processing terminal determines whether the flow meter indication corresponding to the flow meter accumulated amount exists in the flow meter indication corresponding to the existing accumulated amount, thereby determining whether the working flow meter detects water flow in the pipeline.

[0072] Step S30111: If the requirement of the existence of the accumulation amount is met, the preset normal monitoring data is defined as the monitoring status data.

[0073] Among them, if the processing terminal determines that the flow meter reading corresponding to the flow meter cumulative amount exists in the flow meter reading corresponding to the existing cumulative amount, it means that the working flow meter also detects the water flow in the pipeline. At this time, the working flow meter is normal, so the normal monitoring data is defined as the monitoring status data.

[0074] The normal monitoring data refers to data indicating that the monitoring of the working flow meter is normal, and is stored in the processing terminal by the operator.

[0075] Step S30112: If the requirement of the existence of the cumulative amount is not met, the flow meter monitor is controlled to perform depth monitoring on the working flow meter according to a preset depth monitoring trigger signal.

[0076] If the processing terminal determines that the flow meter reading corresponding to the flow meter cumulative amount does not exist in the flow meter reading corresponding to the existing cumulative amount, it means that the working flow meter does not detect the water flow in the pipeline at this time, and the working flow meter may be abnormal. Therefore, the flow meter monitor is controlled according to the depth monitoring trigger signal to perform depth monitoring on the working flow meter. The specific method is referred to Figure 5 steps.

[0077] The depth monitoring trigger signal refers to the trigger data for controlling the flow meter monitor to perform depth monitoring on the working flow meter monitor, and is stored in the processing terminal by the operator.

[0078] Step S3012: If the normal change indication requirement is not met, the monitoring status data is determined according to a preset re-judgment trigger signal.

[0079] If the processing terminal determines that the monitoring change indication does not exist in the indication corresponding to the normal change indication, it indicates that there is no water flow in the pipeline. Therefore, the monitoring status data of the working flow meter is determined according to the re-judgment trigger signal. The specific method is referred to Figure 4 steps.

[0080] The trigger signal is judged to be data for monitoring the working flow meter when there is no water flow in the pipeline, and is stored in the processing terminal by the operator.

[0081] Reference Figure 4 The step of determining the monitoring status data according to the preset re-determination trigger signal includes: Step S400: Determine whether the flow meter cumulative amount meets the preset requirement of the cumulative amount.

[0082] The existence accumulation amount and the requirement of the existence accumulation amount in this step are consistent with the existence accumulation amount and the requirement of the existence accumulation amount in step S3011, and are not described in detail here.

[0083] The processing terminal determines whether the flow meter indication corresponding to the flow meter cumulative amount exists in the flow meter indication corresponding to the existing cumulative amount, thereby determining whether the working flow meter detects the water flow in the pipeline.

[0084] Step S401: If the requirement of the existence of the accumulation amount is not met, the preset normal monitoring data is defined as the monitoring status data.

[0085] If the processing terminal determines that the flow meter reading corresponding to the flow meter cumulative amount does not exist in the flow meter reading corresponding to the existing cumulative amount, it indicates that the working flow meter does not detect the water flow in the pipeline, so the working flow meter is normal, and the monitoring normal data is defined as the monitoring status data. The monitoring normal data in this step is consistent with the monitoring normal data in step S30111, and will not be repeated here.

[0086] Step S402: If the requirement of the existence of the cumulative amount is met, the flow meter monitor is controlled to perform depth monitoring on the working flow meter according to a preset depth monitoring trigger signal.

[0087] Among them, if the processing terminal determines that the flow meter reading corresponding to the flow meter cumulative amount exists in the flow meter reading corresponding to the existing cumulative amount, it means that the working flow meter detects the water flow in the pipeline, but there is no water flow in the pipeline at this time, and the working flow meter may be abnormal. Therefore, the flow meter monitor is controlled according to the depth monitoring trigger signal to perform depth monitoring on the working flow meter. The specific method is referred to Figure 5 steps.

[0088] The depth monitoring trigger signal in this step is consistent with the depth monitoring trigger signal in step S30112, and will not be repeated here.

[0089] Reference Figure 5 The steps of controlling the flow meter monitor to perform depth monitoring on the working flow meter according to the preset depth monitoring trigger signal include: Step S500: Control the flow meter monitor to monitor the working flow meter according to the preset repeated monitoring times, and obtain the normal monitoring times and the abnormal monitoring times.

[0090] Among them, the processing terminal controls the flow meter monitor to monitor the working flow meter according to the number of repeated monitoring times, thereby reducing the probability of misjudgment of the working status of the working flow meter, and detects the number of normal monitoring times and the number of abnormal monitoring times to provide data support for the subsequent determination of the working status of the working flow meter.

[0091] The number of repeated monitoring times refers to the number of times the flow meter monitor monitors the working flow meter, which is an odd number. In the embodiment of the present application, 5 times is taken as an example. The number of normal monitoring times refers to the number of times the flow meter monitor monitors the working flow meter normally, and the number of abnormal monitoring times refers to the number of times the flow meter monitor monitors the working flow meter abnormally. If the flow meter monitor monitors the working flow meter normally, a normal monitoring count is performed, otherwise, a abnormal monitoring count is performed.

[0092] Step S501: Determine whether the number of normal monitoring times is greater than or less than the number of abnormal monitoring times.

[0093] The processing terminal determines whether the number of normal monitoring times is greater than or less than the number of abnormal monitoring times, thereby determining whether the working flow meter is in an abnormal state or a normal state.

[0094] Step S5011: If it is greater than, the preset normal monitoring data is defined as the monitoring status data.

[0095] If the processing terminal determines that the number of normal monitoring times is greater than the number of abnormal monitoring times, it indicates that the probability of the working flow meter being in a normal state is high, so the normal monitoring data is defined as the monitoring state data. The normal monitoring data in this step is consistent with the normal monitoring data in step S30111, and will not be repeated here.

[0096] Step S5012: If it is less than, the preset monitoring abnormal data is defined as monitoring status data.

[0097] If the processing terminal determines that the number of normal monitoring times is less than the number of abnormal monitoring times, it indicates that the probability of the working flow meter being in an abnormal state is relatively high, so the abnormal monitoring data is defined as monitoring state data. The abnormal monitoring data refers to data indicating that the state monitoring result of the flow meter monitor on the working flow meter is abnormal, and is stored in the processing terminal by the operator.

[0098] Reference Figure 6 The steps of calibrating the flow meter monitor and generating calibration result data according to a preset calibration trigger signal include: Step S600: Isolate the flow meter monitor and the working flow meter according to a preset flow meter isolation trigger signal.

[0099] When the flow meter monitor needs to be calibrated, the processing terminal responds to the flow meter isolation trigger signal to isolate the flow meter monitor from the working flow meter. The specific method is as follows: Figure 7 steps to prevent the working flow meter from affecting the calibration of the flow meter monitor during the calibration process.

[0100] The flow meter isolation trigger signal refers to trigger data used to isolate the flow meter monitor from the working flow meter, and is stored in the processing terminal by the operator.

[0101] Step S601: Control a preset water outlet device to discharge water to a flow meter monitor according to a preset benchmark verification flow rate, and obtain a detection verification flow rate of the flow meter monitor.

[0102] Among them, after isolating the flow meter monitor and the working flow meter, the processing terminal controls the water outlet device to discharge water to the flow meter monitor at the benchmark verification flow rate, thereby providing the rated water flow rate, and detects the detection verification flow rate of the flow meter monitor to provide data support for the subsequent determination of the verification results.

[0103] The reference calibration flow rate refers to the fixed water flow rate used to calibrate the flow meter monitor. The specific value is determined by the operator according to the actual situation. The water outlet device refers to the device that provides water flow to the flow meter monitor during the calibration process. A water pump can be used. The detection calibration flow rate refers to the reading of the flow meter monitor during the calibration process, which is detected by the flow meter monitor and sent to the processing terminal.

[0104] Step S602: Determine whether the detection verification flow meets the requirements of the benchmark verification flow.

[0105] Among them, the requirement for the benchmark verification flow rate refers to being within the error range of the benchmark verification flow rate, and the specific error range is determined by the operator based on actual conditions.

[0106] The processing terminal determines whether the detection verification flow is within the error range of the reference verification flow, thereby determining whether the state of the flow meter monitor is normal.

[0107] Step S6021: If it meets the requirements, the preset normal verification data is defined as the verification result data.

[0108] If the processing terminal determines that the detection verification flow is within the error range of the reference verification flow, it means that the flow meter monitor detects the fixed water flow normally, and the flow meter monitor is normal, so the verification normal data is defined as the verification result data. The verification normal data refers to the data with normal verification results for the flow meter monitor, which is stored in the processing terminal by the operator.

[0109] Step S6022: If not, the preset verification abnormality data is defined as the verification result data.

[0110] If the processing terminal determines that the detection verification flow exceeds the error range of the reference verification flow, it means that the flow meter monitor does not detect the fixed water flow. At this time, the flow meter monitor is abnormal, so the verification abnormality data is defined as the verification result data. The verification abnormality data refers to the data with abnormal verification results for the flow meter monitor, which is stored in the processing terminal by the operator.

[0111] Reference Figure 7 The steps of isolating the flow meter monitor and the working flow meter according to the preset flow meter isolation trigger signal include: Step S700: Control the preset water intake valve to close to disconnect the preset water intake pipe and the preset water outlet pipe; the water intake pipe is characterized as a pipe for taking water from the source, the working flow meter is installed on the water intake pipe, the water outlet pipe is characterized as a pipe for water flowing out of the water intake pipe, and the flow meter monitor is installed on the water outlet pipe.

[0112] When isolating the flow meter monitor from the working flow meter, the processing terminal controls the water intake valve to close, thereby disconnecting the water intake pipe and the water outlet pipe, thereby achieving preliminary isolation of the working flow meter and the flow meter monitor.

[0113] The water intake valve refers to the valve on the same pipeline as the flow meter monitor and the working flow meter and is located between the flow meter monitor and the working flow meter. The water intake pipeline refers to the pipeline used to take water from the water source, refer to Figure 8 , which is actually the pipe on the pipeline that is separated from the flow meter monitor by the working flow meter. The outlet pipe refers to the pipe used for the water supply flow to flow out of the water intake pipe, refer to Figure 8 , which is actually the pipeline on the pipeline that is away from the working flow meter with the flow meter monitor as the boundary.

[0114] Step S701: Control a preset diverting valve to open to control the water intake pipeline and the preset diverting pipeline to be connected.

[0115] Among them, after the water intake pipeline and the water outlet pipeline are disconnected, the processing terminal controls the diversion valve to open, thereby connecting the water intake pipeline and the diversion pipeline to prevent the normal water intake and use from being affected during the flow meter monitor calibration process. The diversion pipeline refers to the pipeline that can still ensure normal water intake after isolating the flow meter monitor and the working flow meter. Figure 8 The diversion pipe is installed at the output end of the water intake pipe and is located at the output end of the working flow meter. The diversion valve refers to the valve that controls the connection between the diversion pipe and the water intake pipe. Figure 8 , the flow-changing valve is installed on the flow-changing pipeline.

[0116] Step S702: Control the preset water inlet valve to open to control the water outlet pipe to be connected with the preset water inlet pipe to isolate the flow meter monitor from the working flow meter.

[0117] Among them, after the water intake pipe and the water outlet pipe are disconnected, the processing terminal controls the water inlet valve to open, thereby connecting the water inlet pipe and the water outlet pipe, so that the water outlet device can supply a constant water flow to the flow meter monitor through the water inlet pipe to complete the calibration. At this time, the isolation of the flow meter monitor and the working flow meter is completed.

[0118] The water inlet pipe refers to the water supply pipe when the flow meter monitor is calibrated. Figure 8 The inlet pipe is installed at the input end of the outlet pipe and is located at the input end of the flow meter monitor. The inlet valve refers to the valve that controls the connection between the inlet pipe and the outlet pipe. Figure 8 , the water inlet valve is installed on the water inlet pipe.
