[0025] Figure 2 It is a structural diagram of another BIM-based water pipe network inspection and management system provided in an embodiment of the present application. DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] The embodiment of the utility model discloses a water pipe network inspection management system based on BIM, so as to solve the problem of low efficiency of manual inspection work when the water pipe network has a large and complex distribution range.

[0028] See also Figure 1 , a structural schematic diagram of a BIM-based water supply pipeline inspection management system provided in an embodiment of the present application, the system includes a pipeline data acquisition device, a risk assessment server, a BIM server and an inspection information output terminal.

[0029] The pipe network data acquisition device is connected to the risk assessment server for periodically collecting hydraulic parameters in the water delivery pipe network and sending the hydraulic parameters to the risk assessment server;

[0030] The risk assessment server is connected to the BIM server for evaluating the risk level of each area in the water supply network according to hydraulic parameters, and determining the area to be inspected according to the risk level of each area, and sending the area to be inspected to the BIM server;

[0031] The BIM server is connected to the inspection information output terminal for mapping the area to be inspected into the BIM model of the water pipe network, obtaining the inspection task information including the visualized position of the area to be inspected, and sending the inspection task information to the inspection information output terminal;

[0032] The inspection information output terminal is used to respond to the inspection task information and output the inspection task information to the inspection personnel.

[0033] In order to achieve effective inspection management of the water supply network and improve the accuracy and efficiency of the inspection work, an inspection management system based on BIM technology is adopted. The network data acquisition equipment in the system regularly collects hydraulic parameters in the water supply network, with the purpose of real-time monitoring of the operation status of the network. The collected hydraulic parameters will be sent to the risk assessment server, which will evaluate the risk level of each area of ​​the water supply network based on these parameters, thereby determining the high-risk areas for priority inspection as the areas to be inspected. The information of the area to be inspected is sent to the BIM server, which maps the location of the area to be inspected to the model based on the pre-established BIM three-dimensional model of the water supply network, forming intuitive inspection task information. This allows the inspectors to clearly understand the location of the area to be inspected. The inspection task information will be sent to the inspection information output terminal, which will respond immediately after receiving the task information and convey the inspection task information to the inspectors. The output terminal also has an inspection priority function, which will consider the location of the inspectors and select the nearest inspectors for dispatch, thereby improving the efficiency of the inspection work. Through the application of BIM technology, accurate positioning inspection of water supply pipelines can be achieved, and key areas can be inspected first, thereby improving inspection efficiency.

[0034] In another embodiment, the pipe network data acquisition device includes a plurality of pipe network sensors, and the plurality of pipe network sensors are respectively arranged at various nodes of the water supply pipe network.

[0035] The pipe network data acquisition equipment contains multiple pipe network sensors, which are respectively set at various nodes of the water supply pipe network. The sensors are set at the pipe network nodes because the nodes are the key parts of the pipe network, and the changes in hydraulic parameters will be directly reflected at the nodes. By setting sensors at each node, the hydraulic parameters at different positions in the pipe network can be monitored, and the operating status of the entire pipe network can be fully understood. The specific setting method is to determine the location of all nodes of the pipe network according to the design drawings of the water supply pipe network, and then mark each node in the actual pipe network, and install matching pipe network sensors at each node to realize the monitoring of the water pressure, flow rate, temperature and other parameters of the node.

[0036] It should be noted that in the embodiment of the present application, the nodes have been set up in advance, and the monitoring nodes in the relevant technology can be used. In this way, under the remote control of the pipe network data acquisition equipment, hydraulic data can be collected from all nodes at the same time, the real-time status of the pipe network at different locations can be obtained, and the risk level of the pipe network can be more accurately assessed and the areas that need to be inspected can be determined, thereby guiding subsequent inspections. This setting method can maximize the monitoring level of the water supply pipe network.

[0037] See also Figure 2 , which is a structural diagram of another BIM-based water pipeline inspection and management system provided in an embodiment of the present application.

[0038] Among them, hydraulic parameters include water pressure parameters, flow rate parameters and temperature parameters.

[0039] The pipe network data acquisition equipment may specifically include a water pressure parameter pipe network sensor, a flow rate parameter pipe network sensor, and a temperature parameter pipe network sensor. The water pressure parameter is specifically acquired by the water pressure parameter pipe network sensor, the flow rate parameter is specifically acquired by the flow rate parameter pipe network sensor, and the temperature parameter is specifically acquired by the temperature parameter pipe network sensor.

[0040] The water pressure parameter refers to the water pressure in the pipe network. In the embodiments of the present application, it can be understood as the pressure of the water flow in the pipe. It is monitored and collected in real time by the pressure sensor set at the pipe network node. The water pressure parameter can reflect the pressure of the water flow in the pipe. When the water pressure is too high or too low, it will damage the pipe structure and affect the normal transportation of the water flow.

[0041] The flow rate parameter refers to the flow rate of the water flow in the pipe network. In the embodiments of the present application, it can be understood as the rate at which the water flow in the pipe passes through the pipe per unit time. It is monitored and collected in real time by the flow rate sensors set at the nodes of the pipe network. The flow rate parameter can reflect whether the water flow is flowing smoothly. If there is an abnormal head or pipe blockage, the flow rate will change significantly.

[0042] The temperature parameter refers to the temperature of the water in the pipe network. In the embodiments of the present application, it can be understood as the thermodynamic temperature of the water in the pipe. It is monitored and collected in real time by temperature sensors installed at the nodes of the pipe network. The temperature parameter can reflect whether there are abnormal changes in the water in the pipe. If the water temperature is too high or too low, it means that there may be problems with the pipe network.

[0043] In one embodiment, the risk assessment server further includes a risk level assessment module;

[0044] The risk level assessment module is used to compare the water pressure parameter with the preset water pressure threshold, the flow rate parameter with the preset flow rate threshold, and the temperature parameter with the preset temperature threshold, and evaluate the risk level of each area in the water supply network according to the number of items exceeding the threshold.

[0045] The working method of the risk level assessment module is that first, the water pressure threshold, flow rate threshold and temperature threshold for the normal operation of the pipeline network need to be preset. These thresholds can be determined according to the pipeline design standards, or they can be obtained by accumulating historical operation data of the pipeline network through big data. After obtaining the preset thresholds, the system can compare the water pressure parameters, flow rate parameters and temperature parameters collected in real time with the corresponding thresholds respectively. If a parameter has exceeded its threshold, it is determined that the parameter is abnormal, and the risk of the pipeline area increases by one level. Finally, the number of abnormal parameters in each pipeline area will be counted, and the detailed risk level of the area will be determined according to the number of abnormal parameters. For example, more than two parameter abnormalities are determined as high risk levels. Through the judgment and analysis of the risk level assessment module, the safety hazards and risk levels in various areas of the water supply pipeline network can be clearly identified.

[0046] In one embodiment, the system further includes an inspection feedback module;

[0047] The inspection feedback module is used to receive feedback information sent by the inspectors after completing the inspection of the inspection area, and adjust the preset water pressure threshold and / or the preset flow rate threshold and / or the preset temperature threshold based on the feedback information.

[0048] In order to continuously optimize the preset threshold values ​​of each parameter and more accurately reflect the actual operation status of the pipeline network, the system also sets up an inspection feedback module. The function of the inspection feedback module is to collect on-site feedback information from inspectors to adjust the threshold parameters. Specifically, after the inspectors complete the inspection task of a certain area to be inspected, they will feedback the actual operation status of the area to the inspection feedback module of the system. After the feedback module collects the feedback information of all inspection areas, it combines the parameter judgment results of each area by the risk assessment module to re-analyze and adjust the preset water pressure threshold, flow rate threshold and temperature threshold. For example, if an area is judged to be low risk according to the original preset water pressure threshold, but the inspection feedback shows that the water pressure in the area causes some problems, this means that the original preset water pressure threshold is set too much and the threshold standard needs to be appropriately lowered. After accumulating a large amount of actual operation feedback, the threshold parameters can be continuously optimized to make the risk assessment results more accurate, thereby guiding the inspection and maintenance of the pipeline network.

[0049] In one embodiment, the BIM server further includes a three-dimensional model building module;

[0050] The BIM model construction module is used to obtain the water supply pipeline network construction information from the pipeline network database, and to construct a BIM three-dimensional model in proportion to the water supply pipeline network based on the water supply pipeline network construction information.

[0051] In order to intuitively display the three-dimensional structure of the water supply network and facilitate the spatial positioning and information annotation of the network model, a three-dimensional model construction module is set up in the BIM server to establish the BIM three-dimensional model of the network. The specific working method of the model construction module is to first extract the design CAD drawings of the network, as well as the construction information data such as pipeline material and diameter from the network database. Then import the pipeline construction data into the BIM software, and draw the three-dimensional geometric model of the pipeline according to the parameter settings of the data. Subsequently, the area to be inspected can be directly mapped to the three-dimensional model to form intuitive inspection task information and output it to the inspection personnel. The three-dimensional BIM model can truly reflect the structure of the pipeline network, and the inspection personnel can clearly understand the specific location and pattern of the pipeline network, which helps to improve the accuracy and efficiency of the inspection work.

[0052] In one embodiment, the inspection information output terminal further includes an inspection priority unit;

[0053] The inspection priority unit obtains the location information of each inspection personnel and sends the inspection task information to the inspection information output terminal corresponding to the inspection personnel closest to the area to be inspected.

[0054] In order to improve the efficiency of inspection work and make full use of inspection manpower, the inspection information output terminal is equipped with an inspection priority unit to optimize the dispatch process of inspection tasks. The specific working method of the inspection priority unit is to obtain the current geographical location information of each inspector in real time through GPS or base station positioning. When a new area to be inspected is generated, the system will first calculate the distance of this area relative to each inspector. Then, the inspection priority unit will assign this inspection task to the inspector closest to the inspection area, and send an inspection task notification to him through the inspection information output terminal corresponding to the inspector. This method can reduce the wandering time of the inspectors as much as possible and improve the efficiency of inspection work. At the same time, it also realizes intelligent and dynamic inspection task allocation, and performs reasonable human resource scheduling, rather than simple manual designation or average distribution. Through the application of the inspection priority unit, the location advantages of each inspector can be fully utilized, the strategy of nearby inspection can be adopted, the time cost can be saved to the maximum extent, and the inspection execution efficiency of the system can be improved.

[0055] In the embodiment of the present application, the system further includes a route generation module;

[0056] The route generation module is used to generate an inspection route according to the location information of the inspection personnel, and display the inspection route and the inspection information output terminal corresponding to the inspection personnel.

[0057] In order to further improve the efficiency of inspection work, the system also sets up a route generation module to plan the route of the inspection personnel. The specific working mode of the route generation module is that when the inspection task is assigned, the module will obtain the current location information of the corresponding inspection personnel. Then, based on this location and the location of the area to be inspected, the shortest path algorithm is used to calculate the best inspection path from the current location of the inspection personnel to the inspection area. This path will comprehensively consider the actual road conditions, avoid inaccessible areas, and generate a practical and feasible inspection route. The generated inspection route will be displayed on the digital map and synchronously transmitted to the inspection information output terminal of the corresponding inspection personnel. The inspection personnel can view their inspection routes through the terminal. This method can guide the inspection personnel to carry out inspection work according to the optimal route, without repeated wandering, minimize the route distance, and improve the inspection efficiency. At the same time, the dynamic navigation of the digital map also ensures that the inspection personnel will not get lost and arrive at the inspection site accurately.

[0058] The implementation principle of the name of the embodiment of the present application is: by deploying sensors at the nodes of the pipeline network, monitoring the hydraulic parameters in real time, evaluating the risk level of the pipeline network according to the hydraulic parameters, determining the high-risk inspection areas for priority inspection, and using BIM technology to achieve precise positioning of the pipeline network, so that inspection personnel can quickly locate the pipeline sections that need to be inspected, so as to improve the inspection efficiency, thereby realizing efficient and accurate inspection management of large-scale complex pipeline networks.

[0059] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
