[0062] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0063] In Example 1, Figure 1 The implementation process of the online monitoring and management method for water service status of the smart water service provided by the embodiment of the present invention is shown, and is described in detail below:

[0064] S100: Define the monitoring area of ​​smart water services, draw a plan distribution map of water facilities in the monitoring area, mark the water pipelines, and divide the water pipelines into several segments, obtain influencing factors, configure the health of each segment, construct nodes corresponding to the segments one by one, and transfer the health to the corresponding nodes, and number the nodes incrementally based on the water flow direction of the water pipelines.

[0065] Define the monitoring area of ​​smart water services, draw a plan distribution map of water facilities, and mark the water pipelines in the plan distribution map; divide the water pipelines into multiple segments according to a certain distance, or the material and location of the water pipelines, and determine the influencing factors of the water pipelines, where the influencing factors are the possible causes of water pipeline leakage; determine the health of each segment based on the influencing factors, the greater the health, the greater the possibility of water pipeline leakage; construct a node for each segment; in this embodiment, the node is the basic unit for storing data; transfer the health of each segment to the corresponding node, and number the nodes.

[0066] S200: construct a linked list consisting of a front end and a back end, migrate the nodes whose health is greater than a preset threshold to the front end, and migrate the remaining nodes to the back end, wherein the nodes are arranged in the front end and the back end in the order of numbers.

[0067] Construct a linked list, where the linked list is a collection of nodes, but each node in the linked list is dynamic, and the nodes may be merged or split; split the linked list into the front end and the back end, and determine the size of the health degree and the preset threshold. If the health degree of the node is greater than the preset threshold, the corresponding node is migrated to the front end, and if it is less than or equal to the threshold, the corresponding node is migrated to the back end; the nodes in the front end and the back end are arranged in order of number.

[0068] S300: mounting a plurality of levels in the front end, wherein each level corresponds to a health interval, clustering the nodes in the front end into different levels according to the interval, setting the number of windings of the conductive core wire of each level, and configuring the corresponding relationship between the node and the number of windings through the levels;

[0069] In the back end, all nodes are linked using a single conductive core wire.

[0070] In the front end, multiple levels are mounted, each level corresponds to a health interval, and nodes are classified into corresponding levels according to the health. Each level also corresponds to a winding circle number, that is, each node corresponds to a winding circle number.

[0071] In the present application, a conductive core wire is wound around the outside of a water pipeline and the voltage change of the conductive core wire is monitored to determine whether the water pipeline is leaking. When the water pipeline leaks, water comes into contact with the conductive core wire, causing a change in resistance, thereby causing a change in the voltage of the conductive core wire. Since the health of each segment of the water pipeline is different, by setting a different number of winding turns, blind spots in monitoring can be avoided. For water pipelines with higher health, more winding turns are set, and vice versa.

[0072] For water pipelines whose health level is less than a threshold, the conductive core wire can be directly fixed to the bottom of the water pipeline. No matter where the water pipeline leaks, its bottom will be in contact with water.

[0073] S400: Editing a multi-level monitoring strategy and integrating it into the linked list, collecting voltage changes of each node, intermittently activating the multi-level monitoring strategy at a preset frequency, and determining whether there is a node in the linked list whose voltage change exceeds a preset threshold;

[0074] If so, define the suspected leakage location, adjust the water pressure of the water pipeline where the suspected leakage location is located, and determine whether there is a synchronous change relationship between the water pressure change and the voltage change. If so, trace back the number of the suspected leakage location and send the number to the preset terminal. If not, reduce the health of the suspected leakage location and update the linked list.

[0075] Using a multi-level monitoring strategy, the voltage change of each node is collected to determine whether the voltage change exceeds the preset threshold. If so, it means that the corresponding water pipeline may be leaking. At this time, the corresponding water pipeline is determined as a suspected leaking location, and the water pressure at the suspected leaking location is adjusted to determine whether the voltage at the suspected leaking location will change at the same time. If so, it means that such a simultaneous change relationship is caused by the different leakage amounts. Therefore, it means that a leak has indeed occurred at the suspected leaking location. After determining that a leak has occurred, the number of the node corresponding to the suspected leaking location is traced back and sent to the preset terminal, where the preset terminal can be a terminal for water pipeline maintenance personnel. The multi-level monitoring strategy uses different monitoring strategies to monitor the front end and the back end respectively.

[0076] If the voltage change and water pressure change at the suspected leak location are not synchronized, the health of the suspected leak location is reduced and the suspected leak location is monitored intensively.

[0077] In Example 2, Figure 2 The implementation process of the online monitoring and management method for water service status of the smart water service provided by the embodiment of the present invention is shown. S100 is described in detail below:

[0078] S101: Find out important equipment in the water facility and add the important equipment to the segment.

[0079] Find out the important equipment in the water facilities, mark the location of the important equipment in the plane distribution, and add the important equipment to the segment; in addition to winding the conductive core wire on the water pipeline, you can also wind the conductor core wire on the important equipment.

[0080] S102: Traverse out the influencing factors of each of the segments, where the influencing factors at least include: the age, laying area and material of the water pipeline.

[0081] S103: Based on the influencing factors and health, determining an adjustment method for the segment, wherein the adjustment method at least includes: merging and re-splitting.

[0082] The segments are adjusted according to the influencing factors and health. For example, if the difference in health between two adjacent segments is small, the two adjacent segments can be merged. On the contrary, if there are two areas with large differences in health in the water pipeline in the same segment, the water pipeline needs to be split again.

[0083] In Example 3, Figure 2 The implementation process of the online monitoring and management method for water service status of the smart water service provided by the embodiment of the present invention is shown. S100 is further described in detail below, as follows:

[0084] S104: using a geographic information system in the prior art to locate the position of each segment, generate a label, and insert the label into the corresponding segment.

[0085] Use geographic information systems to determine the location of each segment. In real life, since water pipelines are buried underground, the use of geographic information systems can more intuitively display the location of the segments, use the locations to generate labels, and insert the labels into the corresponding segments.

[0086] S105: Find the segment whose health level is lower than the preset threshold, define it as an abnormal segment, and send the abnormal segment to the preset terminal.

[0087] The segments whose health level is lower than the preset threshold are defined as abnormal segments, and the abnormal segments are sent to the preset terminal so as to focus on monitoring the abnormal segments.

[0088] In Example 4, Figure 3 The implementation process of the online monitoring and management method for water service status of the smart water service provided by the embodiment of the present invention is shown, and S200 is described in detail below, as follows:

[0089] S201: Acquire the construction task of the water pipeline, find out the node corresponding to the construction task, obtain the modification point, and update the health of the modification point.

[0090] Obtain the construction task of the water pipeline, determine the corresponding node, and determine the node as the modification point; for example, due to the needs of municipal construction, the water pipeline at A is excavated. At this time, the modification point is the node corresponding to the water pipeline at A, and the health of the water pipeline at this node is updated.

[0091] S202: Re-determine the position of the modification point in the linked list.

[0092] When the health of the modification point is updated, the size of the health and the preset threshold is re-judged, and based on the judgment result, it is re-determined whether the modification point needs to be migrated in the linked list, where the position migration is from the back end to the front end, or from the front end to the back end.

[0093] In Example 5, Figure 4 The implementation process of the online monitoring and management method of the water service status of the smart water service provided by the embodiment of the present invention is shown, and S300 is described in detail as follows:

[0094] S301: inserting a root node into the linked list, integrating the levels, intervals and winding circles, generating a monitoring ladder diagram, and uploading the monitoring ladder diagram to the root node.

[0095] Insert a root node into the linked list and transfer the monitoring ladder diagram into the root node. The monitoring ladder diagram consists of several ladder items. Each ladder item is a level. Each level corresponds to a health interval and the number of winding circles. According to the health of the node, the node is classified into the corresponding ladder item (level).

[0096] S302: Predict the health of the modification point after the construction task is completed.

[0097] After the construction task is completed, the health of the modification point is predicted.

[0098] S303: Utilize the predicted health level to query the monitoring ladder diagram, traverse the target number of laps, and integrate the modification points and the target number of laps into the construction task.

[0099] When the construction task is completed, the predicted health status is used to query the monitoring ladder diagram, determine the target number of circles, and use the target number of circles to wind the water pipeline at the modification point.

[0100] In Example 6, Figure 4 The implementation process of the online monitoring and management method of the water service status of the smart water service provided by the embodiment of the present invention is shown. S300 is further described in detail as follows:

[0101] S304: Using the multi-level monitoring strategy, monitor all nodes in the linked list;

[0102] The multi-level monitoring strategy is:

[0103] In the front end, along the water flow direction, it is determined in turn whether the voltage change in each node exceeds a preset threshold;

[0104] In the back end, after the nodes are linked, the head and tail are defined to determine whether the voltage changes of the head and tail exceed a preset threshold.

[0105] A multi-level monitoring strategy is used to monitor the front end and the back end separately. In fact, in the front end, the voltage change needs to be judged on a node-by-node basis, while the voltage change of the nodes in the back end needs to be judged as a whole.

[0106] In Example 7, different from Example 1, in this embodiment of the present invention, the method further includes:

[0107] Record the time of voltage change, generate a historical data set using health, voltage change and corresponding time, and input the historical data set into a pre-built machine learning model;

[0108] A potential danger point in the node is identified, and the water pressure is adjusted according to a voltage change at the potential danger point.

[0109] When voltage changes are monitored, the time of the voltage change is recorded and historical data is constructed. The machine learning model is used to predict the next voltage change, identify the potential danger points in the nodes, and adjust the water pressure based on the voltage changes (leakage) at the potential danger points to avoid large-scale leakage in the water pipeline before maintenance personnel perform repairs.

[0110] After locating the leaking node, maintenance personnel need to use equipment such as infrared thermal imaging instruments and acoustic leak detectors to locate the specific location of the leak and carry out maintenance at the appropriate time.
