Description

Technical Field

[0001] The present application relates to the technical field of pipeline detection, and in particular to a method, system, storage medium and intelligent terminal for detecting regional leaking pipelines. Background Art

[0002] During the daily water usage testing process, the water supply company uses water meters to test and record the water usage of each user, so as to make corresponding payment conversions based on the records.

[0003] In the prior art, water used in an area is usually transported from a water supply main to branch pipes of each user. When there is a large difference between the water flow output from the main pipe and the water flow of each branch pipe, the water supply company marks the abnormal data and sends staff to conduct on-site inspections of water meters and pipelines to find the cause of the data difference.

[0004] With respect to the above-mentioned related technologies, the inventor believes that when the flow data difference between the main pipe and each branch pipe is large, arranging staff to conduct on-site inspections increases the workload of the staff, and the inspection steps are relatively cumbersome and need to be improved. Summary of the invention

[0005] In order to facilitate the investigation of the reasons for the difference in water flow data in the main pipe and the branch pipe, the present application provides a regional leaking pipeline detection method, system, storage medium and intelligent terminal.

[0006] In the first aspect, the present application provides a method for detecting regional leaking pipelines, which adopts the following technical solution:

[0007] A method for detecting regional water leakage pipelines, comprising:

[0008] Obtain the total amount of water flow output by the preset main pipe and the water flow component information input by each preset branch pipe;

[0009] Calculate based on each water flow component information to determine the total water volume information;

[0010] Calculate the difference between the total water flow information and the total water volume information to obtain the difference water volume information;

[0011] Determine whether the value corresponding to the difference water volume information is less than a preset allowable threshold;

[0012] If the value corresponding to the difference water volume information is less than the allowable threshold, a normal signal is output;

[0013] If the value corresponding to the differential water volume information is not less than the allowable threshold, an abnormal signal is output, and the measuring equipment preset on each branch pipe for measuring the water volume is controlled to perform self-check, and a feedback signal is output after the self-check is completed;

[0014] Determine whether the feedback signal is consistent with the preset normal operation signal;

[0015] If the feedback signal is consistent with the normal operation signal, a water leakage signal is output;

[0016] If the feedback signal is inconsistent with the normal operation signal, a no-leakage signal is output.

[0017] By adopting the above technical solution, it is determined whether the value corresponding to the difference quantity information exceeds the preset allowable range to determine whether there is an abnormality in the branch pipe. When an abnormality is detected in the branch pipe, the flow detection equipment is self-checked to further determine whether the cause of the abnormality is caused by damage to the detection equipment, thereby reducing the workload of staff in on-site investigation of the cause and improving the efficiency of investigating the cause of abnormal water flow in the branch pipe.

[0018] Optionally, after the water leakage signal is output, the pipeline water leakage detection method further includes:

[0019] Obtaining characteristic image information of a preset detection area;

[0020] Delineating a corresponding water accumulation area in the image corresponding to the characteristic image information according to the preset water leakage characteristics;

[0021] Perform matching analysis on the waterlogging area and the pipeline arrangement information stored in the preset pipeline database to determine the pipeline arrangement information corresponding to the waterlogging area;

[0022] Determine corresponding water flow component information according to the pipeline arrangement information, and define the water flow component information as component information to be measured;

[0023] Calculate the sum of the information of the components to be measured in the same waterlogged area to determine the total amount information of the area;

[0024] Perform matching analysis on the pipeline arrangement information stored in the preset flow database and the safety threshold to determine the safety threshold corresponding to the pipeline arrangement information;

[0025] Determine whether the value corresponding to the regional total amount information is greater than the safety threshold;

[0026] If the value corresponding to the total amount information is greater than the safety threshold, the waterlogged area is defined as a leaking area and an excess signal is output and the branch pipe corresponding to the leaking area is controlled to be closed;

[0027] If the value corresponding to the total amount information is not greater than the safety threshold, the waterlogged area is defined as a non-leakage area, and a non-leakage signal is output.

[0028] By adopting the above technical solution, it is determined whether the value corresponding to the total amount information in the waterlogged area is greater than the safety threshold, so as to determine whether the waterlogged area is a real leakage area, and exclude the waterlogged areas that are not really leaking, thereby improving the efficiency of searching for leakage areas.

[0029] Optionally, before the branch pipe corresponding to the leaking area is closed, the branch pipe control method further includes:

[0030] Obtain the pipe connection information of the branch pipes in the leaking area;

[0031] Determine whether the connection status corresponding to the pipeline connection information is consistent with the preset fire hydrant connection status;

[0032] If the connection status corresponding to the pipeline connection information is consistent with the fire hydrant connection status, the branch pipe is defined as a fire branch pipe;

[0033] If the connection status corresponding to the pipeline connection information is inconsistent with the fire hydrant connection status, the branch pipe is defined as a non-fire branch pipe;

[0034] According to the matching analysis between the fire branch pipe and the image acquisition area stored in the preset fire database, the image acquisition area corresponding to the fire branch pipe is determined;

[0035] Acquire current captured image information in the image capture area;

[0036] Determine whether the features corresponding to the currently collected image information are consistent with the preset firefighting image features;

[0037] If the features corresponding to the currently collected image information are consistent with the firefighting image features, a firefighting operation signal is output;

[0038] If the features corresponding to the currently collected image information are inconsistent with the fire image features, a non-fire operation signal is output and the branch pipe corresponding to the leaking area is controlled to be closed.

[0039] By adopting the above technical solution, it is determined whether the connection conditions of each branch pipe in the leaking area are consistent with the preset fire hydrant connection conditions, so as to further determine whether the leakage situation in the leaking area contains the possibility of the current existence of fire-fighting water. If there is fire-fighting water in the branch pipe, the corresponding branch pipe in the leaking area will not be closed immediately to reduce the impact on fire-fighting operations.

[0040] Optionally, after the fire operation signal is output, the pipeline leakage detection method further includes:

[0041] Determine whether there is a non-fire signal;

[0042] If there is no non-fire signal, the current status of each branch pipe is maintained;

[0043] If there is a non-fire signal, determine whether there is an excessive signal in the leaking area;

[0044] If there is an excessive signal in the leaking area, the branch pipe corresponding to the leaking area is controlled to be closed;

[0045] If there is no excessive signal in the leaking area, the current state of each branch pipe is maintained.

[0046] By adopting the above technical solution, after determining that there is water for fire fighting, the non-fire fighting signal of the leaking area is continuously acquired to determine whether the fire fighting operation is over, so as to judge the excessive signal in the branch pipe of the leaking area after the fire fighting operation is over, so as to further eliminate the situation that the branch pipe of the leaking area leaks during the fire fighting water supply, so as to facilitate the closing control of the leaking branch pipe.

[0047] Optionally, also include:

[0048] Get branch number information;

[0049] Determine the closing sorting information according to the branch pipe number information and the preset sorting rules;

[0050] According to the order corresponding to the closing order information, the branches in the leaking area are controlled to be closed in turn, and the closed branches are defined as detection branches;

[0051] Determine the branch pipe condition information of the branch pipes other than the detection branch pipe according to the pipeline arrangement information and the detection branch pipe;

[0052] Perform matching analysis on the branch pipe condition information stored in the preset threshold database and the permitted threshold value to determine the permitted threshold value corresponding to the branch pipe condition information;

[0053] Determine whether the value corresponding to the regional total amount information is greater than the permitted threshold;

[0054] If the value corresponding to the regional total amount information is greater than the permitted threshold, each branch pipe will continue to be controlled to be closed in turn;

[0055] If the value corresponding to the regional total amount information is not greater than the permitted threshold, the closing operation of each branch pipe is stopped and the detection branch pipe is defined as a leaking branch pipe.

[0056] By adopting the above technical solution, the branches in the leaking area are sorted according to the preset sorting rules, and the detection branches are closed in turn, so as to judge the specific leaking branches in the closed pipeline according to the corresponding branch situation information when different branches are closed and the permitted threshold, so as to close the correct leaking branch and reduce the impact on the water use of normal branches when the non-leaking branches are closed.

[0057] Optionally, the method for controlling the closing of the branch pipe further includes:

[0058] The set of branches corresponding to the pipeline arrangement information is defined as a detection set;

[0059] Determine a closed sub-set in the detection set according to a preset demarcation rule, and determine an open sub-set according to the detection set and the closed sub-set;

[0060] Control the closure of each branch pipe in the closure sub-set and define the closed branch pipe as a detection branch pipe;

[0061] Determine whether the value corresponding to the regional total amount information is greater than the permitted threshold;

[0062] If the value corresponding to the regional total amount information is greater than the permitted threshold, the open sub-set is updated to a new detection set;

[0063] If the value corresponding to the regional total amount information is not greater than the permitted threshold, the closed sub-set is updated to the new detection set;

[0064] Get the branch quantity information of the branch in the detection set;

[0065] Determine whether the quantity value corresponding to the branch pipe quantity information is equal to one;

[0066] If the quantity value corresponding to the branch pipe quantity information is equal to one, the branch pipes in the detection set are controlled to be closed and the detection branch pipe is defined as a leaking branch pipe;

[0067] If the quantity value corresponding to the branch pipe quantity information is not equal to one, the detection set continues to be updated.

[0068] By adopting the above technical solution, the value of the regional total amount information after the detection branch pipe is closed is compared with the permitted threshold. When the value corresponding to the branch pipe total amount information is not greater than the permitted threshold, the detection branch pipe is determined to be a specific leaking branch pipe, and the information of the leaking branch pipe is accurately obtained to facilitate the closure of the leaking branch pipe.

[0069] Optionally, the delineation rules include:

[0070] Determine the total amount of closing of the closed subset according to the branch quantity information and the preset fixed ratio value;

[0071] Determine whether the quantity value corresponding to the closing total amount information is an integer;

[0072] If the quantity value corresponding to the closing total amount information is an integer, an integer signal is output;

[0073] If the quantity value corresponding to the closing total amount information is not an integer, determining whether the quantity value corresponding to the closing total amount information is less than two;

[0074] If the quantity value corresponding to the closing total amount information is less than two, the quantity value corresponding to the closing total amount information is updated to one;

[0075] If the quantity value corresponding to the closing total amount information is not less than two, the quantity value corresponding to the closing total amount information is rounded along a preset fixed direction, and the rounded value is used to update the quantity value corresponding to the closing total amount information.

[0076] By adopting the above technical solution, it is determined whether the number of branches obtained by dividing the branches according to the preset fixed ratio value is an integer, so as to determine the number of branches corresponding to the closed total amount information. When the number value corresponding to the total amount information is less than two, it is determined that the number of remaining closed subsets and open subsets are both one. If the number value corresponding to the total amount information is not less than two, it is still necessary to detect the remaining branches to determine the branches with water leakage.

[0077] In a second aspect, the present application provides a leaking pipe detection system, which adopts the following technical solution:

[0078] A leaking pipeline detection system, comprising:

[0079] An acquisition module, used to obtain the total amount of water flow output by the preset main pipe and the water flow component information of each preset branch pipe;

[0080] A processing module, connected to the acquisition module and the judgment module, for storing and processing information;

[0081] The processing module calculates the total water volume information according to the information of each flow water component, and calculates the difference between the total water volume information and the total water flow volume information to determine the difference water volume information;

[0082] A judgment module, used to judge whether the value corresponding to the difference water volume information is within a preset allowable range;

[0083] If the judgment module determines that the value corresponding to the differential water volume information is within the preset allowable range, the processing module outputs normal information;

[0084] If the judgment module determines that the value corresponding to the differential water volume information is not within the preset allowable range, the processing module outputs an abnormal signal, controls the flow meter preset on each branch pipe to perform self-check, and outputs a feedback signal after the self-check is completed;

[0085] A judgment module, used to judge whether the feedback signal is consistent with the preset normal operation signal;

[0086] If the judging module determines that the feedback signal is consistent with the preset normal operation signal, the processing module outputs a water leakage signal;

[0087] If the judging module determines that the feedback signal is inconsistent with the preset normal operation signal, the processing module outputs a no-leakage signal.

[0088] By adopting the above technical solution, the judgment module determines whether the value corresponding to the difference quantity information exceeds the preset allowable range to determine whether there is an abnormality in the branch pipe. When an abnormality is detected in the branch pipe, the processing module performs a self-inspection on the flow detection equipment to further determine whether the cause of the abnormality is caused by damage to the detection equipment, thereby reducing the workload of staff in conducting on-site investigation of the cause and improving the efficiency of investigating the cause of abnormal water flow in the branch pipe.

[0089] In a third aspect, the present application provides a smart terminal, which adopts the following technical solution:

[0090] An intelligent terminal comprises a memory and a processor, wherein the memory stores a computer program which can be loaded by the processor and execute any one of the above-mentioned regional water leakage pipeline detection methods.

[0091] By adopting the above technical solution and using intelligent terminals, it is determined whether the value corresponding to the difference quantity information exceeds the preset allowable range to determine whether there is an abnormality in the branch pipe. When an abnormality is detected in the branch pipe, the flow detection equipment is self-checked to further determine whether the cause of the abnormality is caused by damage to the detection equipment, thereby reducing the workload of staff in on-site investigation of the cause and improving the efficiency of investigating the cause of abnormal water flow in the branch pipe.

[0092] In a fourth aspect, the present application provides a computer storage medium capable of storing corresponding programs, which is convenient for troubleshooting the cause of water leakage in the leaking pipes in the area, thereby reducing the workload of the staff for troubleshooting the leaking pipes, and adopts the following technical solutions:

[0093] A computer-readable storage medium stores a computer program that can be loaded by a processor and execute any of the above-mentioned regional water leakage pipeline detection methods.

[0094] By adopting the above technical scheme, a computer program of a pipeline leakage detection method is stored in a storage medium, and it is determined whether the value corresponding to the difference quantity information exceeds a preset allowable range to determine whether there is an abnormality in the branch pipe. When an abnormality is detected in the branch pipe, a self-inspection of the flow detection equipment is performed to further determine whether the cause of the abnormality is caused by damage to the detection equipment, thereby reducing the workload of staff in conducting on-site investigation of the cause and improving the efficiency of investigating the cause of abnormal water flow in the branch pipe.

[0095] In summary, the present application includes at least one of the following beneficial technical effects:

[0096] 1. Determine whether the value corresponding to the difference quantity information exceeds the preset allowable range to determine whether there is an abnormality in the branch pipe. When an abnormality is detected in the branch pipe, the flow detection equipment is self-checked to further determine whether the cause of the abnormality is caused by damage to the detection equipment, thereby reducing the workload of the staff in the field investigation and improving the efficiency of the investigation of the abnormal cause of the branch pipe water flow;

[0097] 2. By judging whether the value corresponding to the total amount information in the technical area is greater than the safety threshold, it is determined whether the waterlogged area is a real leaking area, thereby improving the efficiency of finding the real leaking area;

[0098] 3. By judging whether the connection status of each branch pipe in the leaking area is consistent with the preset fire hydrant connection status, it is further determined whether there is water for fire fighting in the leaking area. If there is water for fire fighting in the current leaking area, the branch pipe in the leaking area cannot be closed immediately to reduce the impact on fire fighting operations.

[0107] In order to make the purpose, technical solutions and advantages of this application more clear, the following Figure 1-8It 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.

[0108] The embodiments of the present invention are further described in detail below in conjunction with the accompanying drawings.

[0109] The embodiment of the present application discloses a method for detecting leaking pipes, which first obtains the water flow in the main pipe and the branch pipes, and calculates the total water flow of each branch pipe, so as to calculate the water flow difference between the main pipe and the branch pipes, and compare the water flow difference with a preset allowable threshold value to determine whether there is an abnormal situation of water leakage in the branch pipe, and analyze the abnormal situation of water leakage to reduce the workload of staff when conducting on-site investigation of abnormal water leakage.

[0110] Reference Figure 1 , the leaking pipeline detection method includes the following steps:

[0111] Step S100: obtaining the total amount of water flow outputted by the preset main pipe and the amount of water flow inputted by each preset branch pipe.

[0112] The main pipe is a pipe pre-installed in the area for water flow input when the pipeline is built. It is set by the staff according to the needs when the pipeline is built in the area. It will not be repeated here. The branch pipe is a pipe installed in the area by the staff according to the needs when the pipeline is built. There are multiple branch pipes, and the input ends of the multiple branch pipes are connected to the output end of the main pipe. The total amount of water flow corresponding to the total amount of water flow information is the water flow rate flowing into the main pipe per unit time. The water flow component corresponding to the water flow component information is the water flow volume input from the main pipe to the branch pipe per unit time. The unit time can be one minute or other time. It is set by the staff according to actual needs. It will not be repeated here. The water flow component information and the total amount of water flow information can be obtained through the measuring equipment used to measure the water flow.

[0113] Step S101: Calculate based on the information of each water flow component to determine the total water volume information.

[0114] The total water volume corresponding to the total water volume information is the sum of the water flow component values ​​of each branch pipe, which is obtained by accumulating the water flow component values ​​of each branch pipe.

[0115] Step S102: Calculate the difference between the total water flow information and the total water volume information to obtain the difference water volume information.

[0116] The difference value corresponding to the differential flow information is the water loss from the main pipe to the branch pipe, and the calculation method is to subtract the water value corresponding to the total water flow information from the water value corresponding to the total water flow information.

[0117] Step S103: Determine whether the value corresponding to the difference water volume information is less than a preset allowable threshold.

[0118] The allowable threshold is the maximum value of the allowable water flow loss when there is no water leakage in the branch pipe set by the staff. The purpose of the judgment is to find out whether there is water leakage in the branch pipe.

[0119] Step S104: If the value corresponding to the difference water volume information is less than the allowable threshold, a normal signal is output.

[0120] When the value corresponding to the difference water volume information is less than the allowable threshold, it means that the water flow transmission between the main pipe and the branch pipe is in a normal transmission state and the loss is small, that is, there is no water leakage in the branch pipe. At this time, a normal signal is output for identification. The normal signal can be an indicator light or a prompt sound at the terminal, which is set by the staff according to the actual situation. It will not be elaborated here. The output normal signal is for the staff to know the specific situation of the branch pipe.

[0121] Step S105: If the value corresponding to the difference water volume information is not less than the allowable threshold, an abnormal signal is output, and the measuring equipment preset on each branch pipe for measuring the water volume is controlled to perform self-inspection, and a feedback signal is output after the self-inspection is completed.

[0122] When the value corresponding to the difference water volume information is not less than the allowable threshold, it means that there is a flow mismatch in the water flow transmission between the main pipe and the branch pipe, and the loss is large, that is, there is a water leakage in the branch pipe. At this time, an abnormal signal is output for identification, so as to facilitate further analysis of the situation later; the measuring equipment is a device installed on each branch pipe to detect the water flow of the branch pipe. It can be an electromagnetic flowmeter or an ultrasonic flowmeter. The specific structure is set by the staff according to the actual situation and will not be elaborated on; when the abnormal signal is output, the detection equipment of each branch pipe can perform self-inspection to determine whether the detection equipment is damaged and the flow detection abnormality occurs. The self-inspection function is carried by the measuring equipment itself and is common knowledge to those skilled in the art and will not be elaborated on; when the self-inspection is completed, a feedback signal will be output, and the feedback signal includes a normal signal and an abnormal signal. The normal signal represents that the measuring equipment is in an undamaged state, and the abnormal signal represents that the measuring equipment is in a damaged state.

[0123] Step S106: determining whether the feedback signal is consistent with the preset normal operation signal;

[0124] The normal operation signal is the signal corresponding to the normal operation of the flow meter. The purpose of the judgment is to determine whether the flow meter has any abnormal operation and whether the cause of the water leakage is caused by damage to the flow meter.

[0125] Step S107: If the feedback signal is consistent with the normal operation signal, a water leakage signal is output.

[0126] When the feedback signal is consistent with the normal operation signal, it means that the detection equipment is in normal working condition. At this time, a water leakage signal is output for identification to facilitate further analysis of the branch pipe situation.

[0127] Step S108: If the feedback signal is inconsistent with the normal operation signal, a no-leakage signal is output.

[0128] When the feedback signal is inconsistent with the normal operating signal, it means that the detection equipment may be damaged and is in an abnormal working state. At this time, a no-leakage signal is output for identification, so as to facilitate the subsequent inspection and replacement of the damaged measuring equipment.

[0129] Reference Figure 2 After the water leakage signal is output, the pipeline water leakage detection method also includes:

[0130] Step S200: Acquire characteristic image information of a preset detection area.

[0131] The image corresponding to the characteristic image information is an image of the water use area, which is acquired by a camera preset in the area. When the branch pipes and the main pipe are buried underground, the camera acquires the ground conditions. When the branch pipes and the main pipe are set on the ground, the camera acquires the surface image features of the pipeline. The camera has a wide-angle shooting function, and the direction of the camera is set by the staff according to the actual situation, which will not be elaborated here.

[0132] Step S201: Delineating a corresponding water accumulation area in an image corresponding to the characteristic image information according to a preset water leakage feature.

[0133] The water leakage feature is the image feature set in advance by the staff when a water leakage occurs. The feature can be a large area of ​​water accumulation or water constantly gushing out from underground. The specific features are set differently by the staff according to different situations. Different water leakage features are collected and sorted to establish a corresponding database for water leakage features; the water accumulation area is the area where the water leakage feature appears in the image corresponding to the characteristic image information, that is, the area may have branch pipe leakage. The water accumulation area is delineated to facilitate the subsequent further analysis of the branch pipe leakage situation. The image comparison method is a conventional technical means of those skilled in the art and will not be elaborated on.

[0134] Step S202: performing a matching analysis based on the waterlogging area and the pipeline arrangement information stored in the preset pipeline database to determine the pipeline arrangement information corresponding to the waterlogging area.

[0135] The pipeline arrangement information corresponds to the pipeline arrangement situation of the pipeline in the water accumulation area. For example, there are four branch pipes A, B, C, and D. The branch pipes under the water accumulation area are A and B respectively. Then, the information of branch pipes A and B is the pipeline arrangement information. The pipelines corresponding to each area are divided on the construction drawings. The area can be a large area or a small area. Different water accumulation areas correspond to different pipeline arrangement information. The staff can establish a pipeline database according to different water accumulation areas and the corresponding pipeline arrangement information. The establishment method is a conventional technical means of those skilled in the art and will not be elaborated on.

[0136] Step S203: Determine corresponding water flow component information according to the pipeline arrangement information, and define the water flow component information as component information to be measured.

[0137] The water flow component situation corresponding to the water flow component information in the water accumulation area is: for example, there are four branches A, B, C, and D, and the branches in the water accumulation area are A and B respectively. Then the water flow component information in the water accumulation area is the water flow components of branches A and B. The water flow component information in the water accumulation area is defined as the component information to be measured and marked to facilitate the subsequent call of the component information to be measured.

[0138] Step S204: Calculate the sum of the component information to be measured in the same waterlogged area to determine the regional total amount information.

[0139] The regional water flow volume corresponding to the regional total volume information is the sum of the water flow component values ​​of each branch pipe in the waterlogged area, and the calculation method is to accumulate and sum the water flow components in multiple branches corresponding to the component information to be measured.

[0140] Step S205: performing a matching analysis on the pipeline arrangement information stored in the preset flow database and the safety threshold to determine the safety threshold corresponding to the pipeline arrangement information.

[0141] The safety threshold is the maximum value of the water loss allowed when no water leakage occurs in the branch pipes in the waterlogged area, which is set by the staff. The safety threshold corresponding to the branch pipes in the waterlogged area is stored in the flow database, and the corresponding safety threshold can be obtained according to the corresponding branch pipe matching. The method for establishing the flow database is a common technical means for those skilled in the art and will not be described in detail.

[0142] Step S206: Determine whether the value corresponding to the regional total amount information is greater than the safety threshold.

[0143] The purpose of the judgment is to find out whether there is a leaking branch pipe in the waterlogged area, so as to facilitate the subsequent analysis of the area with the leaking branch pipe.

[0144] Step S207: If the value corresponding to the total amount information is greater than the safety threshold, the waterlogged area is defined as a leaking area, an excess signal is output, and the branch pipe corresponding to the leaking area is controlled to be closed.

[0145] When the value corresponding to the total amount information is greater than the safety threshold, it means that the water flow transmission loss of the branch pipe in the waterlogged area is large, that is, there is a branch pipe leakage. The waterlogged area is defined as a leakage area and marked, and the corresponding branch pipe in the leakage area is controlled to be closed to reduce the waste caused by leakage.

[0146] Step S208: If the value corresponding to the total amount information is not greater than the safety threshold, the waterlogged area is defined as a non-leakage area, and a non-leakage signal is output.

[0147] When the value corresponding to the total amount information is not greater than the safety threshold, it means that the water transmission loss of the branch pipe in the waterlogged area is small, that is, there is no branch pipe leakage, and the waterlogging is not caused by branch pipe leakage. At this time, a no leakage signal is output.

[0148] Reference Figure 3 Before the branch pipe corresponding to the leaking area is closed, the branch pipe control method also includes:

[0149] Step S300: Obtain the pipe connection information of the branch pipes in the water leakage area.

[0150] The connection situation corresponding to the pipeline connection information is the situation in which the branch pipe in the leaking area is connected to other water pipes. The pipeline connection information can be obtained from the drawings when the pipeline is constructed.

[0151] Step S301: Determine whether the connection status corresponding to the pipeline connection information is consistent with the preset fire hydrant connection status.

[0152] The preset fire connection situation is that the branch pipe in the leaking area is connected to the fire hydrant. The purpose of the judgment is to know whether the branch pipe connected to the fire hydrant can be closed.

[0153] Step S302: If the connection status corresponding to the pipeline connection information is consistent with the fire hydrant connection status, the branch pipe is defined as a fire branch pipe.

[0154] When the connection status corresponding to the pipeline connection information is consistent with the fire hydrant connection status, it means that there is a connection with the fire hydrant in the branch pipe. At this time, the branch pipe is defined as a fire branch pipe and marked to facilitate further analysis of the fire branch pipe.

[0155] Step S303: If the connection status corresponding to the pipeline connection information is inconsistent with the fire hydrant connection status, the branch pipe is defined as a non-fire branch pipe.

[0156] When the connection status corresponding to the pipeline connection information is inconsistent with the fire hydrant connection status, it means that there is no connection between the branch pipe and the fire branch pipe in the leaking area. At this time, the branch pipe is defined as a non-fire branch pipe and marked.

[0157] Step S304: performing matching analysis between the fire branch pipes and the image acquisition regions stored in the preset fire database to determine the image acquisition region corresponding to the fire branch pipes.

[0158] The area corresponding to the image acquisition area is the area where the fire branch pipe and the branch pipe in the leakage area are connected. The location of the connection between the fire branch pipe and the branch pipe in the leakage area can be determined through matching analysis of the fire database, and the image acquisition area is marked to facilitate subsequent call and analysis of the image in the image acquisition area.

[0159] Step S305: Acquire current captured image information in the image capture area.

[0160] The image corresponding to the collected image information is an image within the water leakage area, which can be obtained by shooting with a camera.

[0161] Step S306: Determine whether the features corresponding to the currently collected image information are consistent with the preset fire protection image features.

[0162] The fire image feature is a feature when a firefighting operation exists in the area set in advance by the staff. The feature can be fire-related image features such as fire trucks, firefighting uniforms, and fire hoses in the collection area. The specific features are set differently by the staff according to the actual situation, and different fire image features are sorted out to establish a corresponding database of fire image features. The purpose of the judgment is to find out whether there is water for firefighting in the collection area, so as to facilitate further analysis and control of the fire branch pipe when there is water for firefighting.

[0163] Step S307: If the features corresponding to the currently collected image information are consistent with the firefighting image features, a firefighting operation signal is output.

[0164] When the features corresponding to the currently collected image information are consistent with the firefighting image features, it indicates that there is a firefighting operation in the collection area. At this time, a firefighting operation signal is output and marked to facilitate further analysis of the branch pipe.

[0165] Step S308: If the features corresponding to the currently collected image information are inconsistent with the fire image features, a non-fire operation signal is output, and the branch pipe corresponding to the leaking area is controlled to be closed.

[0166] When the features corresponding to the current collected image information are inconsistent with the fire image features, it means that there is a connection between the branch pipe and the fire hydrant in the current collection area, but there is no firefighting operation, that is, there is a water leakage in the branch pipe in the current collection area, and the corresponding branch pipe in the leaking area is controlled to be closed to reduce waste.

[0167] Reference Figure 4 After the fire operation signal is output, the pipeline leakage detection method also includes:

[0168] Step S400: Determine whether there is a non-fire signal.

[0169] The purpose of the judgment is to know whether the firefighting operation is completed, so that after the firefighting operation is completed, further leakage detection can be carried out on the branch pipes in the leaking area without affecting the water use for firefighting work.

[0170] Step S401: If there is no non-fire signal, the current status of each branch pipe is maintained.

[0171] When there is no non-fire signal, it means that the fire branch pipes in the leaking area are still supplying water for firefighting operations, and the branch pipes in the leaking area cannot be closed, so the current status of each branch pipe is maintained.

[0172] Step S402: If there is a non-fire signal, determine whether there is an excessive signal in the water leakage area.

[0173] When there is a non-fire signal, it means that the firefighting operation in the leaking area is over. The purpose of judging whether there is an excessive signal in the leaking area is to find out whether there is a leak when the fire branch pipe is not supplying water for the firefighting operation, so as to facilitate the subsequent control of the leaking fire branch pipe.

[0174] Step S403: If there is an excessive signal in the water leakage area, the branch pipe corresponding to the water leakage area is controlled to be closed.

[0175] When there is an excessive signal in the leaking area, it means that there is a leak in the fire branch pipe in the leaking area. At this time, the corresponding leaking fire branch pipe should be closed to reduce water waste.

[0176] Step S404: If there is no excessive signal in the water leakage area, the current state of each branch pipe is maintained.

[0177] When there is no excessive signal in the leakage area, it means that there is no branch pipe leakage in the current leakage area, and the branch pipe is not operated at this time.

[0178] Reference Figure 5 , pipeline leakage detection methods also include:

[0179] Step S500: Obtain branch pipe number information.

[0180] The numbering situation corresponding to the branch pipe numbering information is the branch pipe number in the leaking area. The branch pipe number can be obtained through the pipeline drawing when the branch pipe is constructed. Each branch pipe has a corresponding number, and the numbering has a sequence. The branch pipe number can be recorded in Arabic numerals or other text. The specific number is set by the staff according to the actual situation and will not be elaborated on.

[0181] Step S501: Determine closing sorting information according to branch pipe number information and preset sorting rules.

[0182] The closing order corresponding to the closing sorting information can be determined according to the order of the branch pipe numbers. The sorting rule is to arrange the branches in positive or reverse order according to the branch pipe number information. It is set by the staff and will not be elaborated on.

[0183] Step S502: Control the branches in the leaking area to be closed in turn according to the order corresponding to the closing order information, and define the closed branches as detection branches.

[0184] The branch pipes in the leaking area are closed in turn according to the closing sequence, that is, the branch pipes are closed and then opened within a unit time, and the currently closed branch pipes are defined as detection branches and marked to facilitate further analysis and control of the detection branches. The unit time is set by the staff according to needs and will not be elaborated on.

[0185] Step S503: determining branch pipe condition information of branch pipes other than the detected branch pipe according to the pipeline arrangement information and the detected branch pipes.

[0186] The branch pipe corresponding to the branch pipe situation information is a branch pipe other than the detection branch pipe in the water leakage area. The corresponding branch pipe is defined as the branch pipe situation information and marked to facilitate subsequent calling and analysis of the branch pipe situation information.

[0187] Step S504: performing a matching analysis between the branch pipe condition information stored in the preset threshold database and the permitted threshold value to determine the permitted threshold value corresponding to the branch pipe condition information.

[0188] The permissible threshold is the maximum value of the water flow loss allowed when no leakage occurs in the branch pipe, which is set by the staff. When the corresponding branch pipe serial number is input, the permissible threshold of the corresponding branch pipe can be matched from the threshold database. The establishment of the threshold database is a common technical means for technicians in this field and will not be elaborated on. The permissible threshold is obtained to facilitate further analysis of the branch pipe.

[0189] Step S505: Determine whether the value corresponding to the regional total amount information is greater than the permitted threshold.

[0190] The purpose of the judgment is to find out whether there is a leaking branch pipe in the area, so as to facilitate further control of the branch pipes in the area.

[0191] Step S506: If the value corresponding to the regional total amount information is greater than the permitted threshold, then each branch pipe is continuously controlled to be closed in turn.

[0192] When the value corresponding to the regional total amount information is greater than the permitted threshold, it means that there is no water leakage in the closed branch pipe. At this time, the remaining branch pipes are controlled to be closed in turn to detect the remaining branch pipes.

[0193] Step S507: If the value corresponding to the regional total amount information is not greater than the permitted threshold, the closing operation of each branch pipe is stopped and the detected branch pipe is defined as a leaking branch pipe.

[0194] When the value corresponding to the regional total amount information is not greater than the permitted threshold, it indicates that the closed branch pipe is leaking. At this time, the inner wall of the branch pipe is controlled and the branch pipe is defined as a leaking branch pipe for easy identification.

[0195] Reference Figure 6 , the method for controlling the closing of the branch pipe also includes:

[0196] Step S600: defining a set where each branch pipe corresponding to the pipeline arrangement information exists as a detection set.

[0197] The pipelines corresponding to the pipeline arrangement information are divided into sets to facilitate subsequent analysis of the branches in the set.

[0198] Step S601: Determine a closed sub-set in the detection set according to a preset demarcation rule, and determine an open sub-set according to the detection set and the closed sub-set.

[0199] The demarcation rules are pre-set by the staff. For example, multiple branches in the set are divided according to a fixed number and order, and the divided branches are defined as closed sub-sets for identification; the method for determining the open sub-set is to divide the branches except the closed sub-set, and define the divided set as an open sub-set.

[0200] Step S602: Control each branch in the closed subset to close and define the closed branch as a detection branch.

[0201] The branches in the closed sub-collection are closed in turn according to the order of sorting to analyze the closed branches, and the closed branches are defined as detection branches and marked to facilitate subsequent call analysis of the detection branches.

[0202] Step S603: Determine whether the value corresponding to the regional total amount information is greater than the permitted threshold.

[0203] The purpose of the judgment is to find out whether there is a water leakage in the branch pipe in the closed sub-set divided according to the demarcation rules, so as to facilitate further analysis of the branch pipe in the closed sub-set.

[0204] Step S604: If the value corresponding to the regional total amount information is greater than the permitted threshold, the enabled subset is updated to a new detection subset.

[0205] When the value corresponding to the regional total amount information is greater than the permitted threshold, it means that there is no water leakage in the corresponding branch pipe in the closed sub-collection. At this time, the open sub-collection is updated to a new detection collection to check the branch pipes in the open sub-collection for detection and analysis.

[0206] Step S605: If the value corresponding to the regional total amount information is not greater than the permitted threshold, the closed subset is updated to a new detection subset.

[0207] When the value corresponding to the regional total amount information is not greater than the permitted threshold, it means that there is no leaking branch pipe in the open sub-set in the new detection set. At this time, the closed sub-set in the new detection set is updated to the new detection set to further analyze the branch pipes in the detection set.

[0208] Step S606: Obtain branch quantity information of the branches in the detection set.

[0209] The number corresponding to the branch pipe quantity information is the number of branch pipes in the detection set, which can be obtained through the drawings when the branch pipes are constructed.

[0210] Step S607: Determine whether the quantity value corresponding to the branch pipe quantity information is equal to one.

[0211] The purpose of the judgment is to know when the branch ends in the process of continuous division of the detection set.

[0212] Step S608: If the quantity value corresponding to the branch pipe quantity information is equal to one, the branch pipes in the detection set are controlled to be closed and the detection branch pipe is defined as a leaking branch pipe.

[0213] When the quantity value corresponding to the branch pipe quantity information is equal to one, it means that when it is determined that there is a branch pipe leak, no leaking branch pipe is found in the previous detection branches, and the last remaining branch pipe is the leaking branch pipe. The branch pipe is defined as a leaking branch pipe and marked to control the closing of the leaking branch pipe.

[0214] Step S609: If the quantity value corresponding to the branch pipe quantity information is not equal to one, continue to update the detection set.

[0215] When the quantity value corresponding to the branch pipe quantity information is not equal to one, it means that no water leakage occurs in the previously detected branch pipes, and the number of remaining branch pipes to be closed is more than one, and the detection set continues to be divided.

[0216] Reference Figure 7 , the demarcation rules include:

[0217] Step S700: Determine the total amount of closed subsets according to branch quantity information and a preset fixed ratio value.

[0218] The total number of branches corresponding to the total amount information of closure is the number of branches calculated based on the fixed ratio value. The calculation method is to multiply the total number of branches in the detection set by the fixed ratio value to obtain the number of branches in the closed subset. The specific value of the fixed ratio value is set by the staff according to the actual situation and will not be elaborated on.

[0219] Step S701: Determine whether the quantity value corresponding to the closing total amount information is an integer.

[0220] The purpose of the judgment is to determine the number of branches in the closed subset, so as to facilitate the subsequent analysis of the closed subset and the calculation of the number of branches in the open subset.

[0221] Step S702: If the quantity value corresponding to the closing total amount information is an integer, an integer signal is output.

[0222] When the quantity value corresponding to the total amount information of closure is an integer, it means that the number of branches in the closure subset can be rounded normally, and an integer signal is output at this time.

[0223] Step S703: If the quantity value corresponding to the closing total amount information is not an integer, determine whether the quantity value corresponding to the closing total amount information is less than two.

[0224] When the quantity value corresponding to the closed total amount information is not an integer, it means that the quantity corresponding to the closed total amount information needs to be rounded. Before rounding, it is judged whether the quantity value corresponding to the closed total amount information is less than two. The purpose of the judgment is to know whether the open sub-set needs to be divided in order to analyze the closed sub-set.

[0225] Step S704: if the quantity value corresponding to the closing total amount information is less than two, the quantity value corresponding to the closing total amount information is updated to one.

[0226] When the quantity value corresponding to the closed total amount information is less than two, it means that there is only one branch pipe left in the closed sub-set. At this time, the quantity value of the closed sub-set is updated to one to facilitate subsequent analysis of the branches in the closed sub-set.

[0227] Step S705: If the quantity value corresponding to the closing total amount information is not less than two, the quantity value corresponding to the closing total amount information is rounded along a preset fixed direction, and the rounded value is used to update the quantity value corresponding to the closing total amount information.

[0228] When the quantity value corresponding to the closed total amount information is not less than two, it means that the corresponding leaking pipe has not been determined. At this time, the quantity value corresponding to the closed total amount information is rounded along a fixed direction to divide the number of pipes in the closed subset, where the fixed direction can be upward or downward, which is set by the staff according to actual conditions and will not be elaborated on. The rounded value is used to update the quantity value corresponding to the closed total amount information to realize the change in the number of pipes in the closed subset.
