Technical Field

[0001] The present invention relates to the technical field of municipal pipe network monitoring, and particularly relates to a real-time update method for a municipal pipe network monitoring system and a real-time update device for a municipal pipe network monitoring system. Background Art

[0002] With the continuous development of cities, the urban scale is constantly expanding, and the corresponding urban water supply demand is also constantly expanding. As a result, the municipal pipe network system of the city is becoming more and more complex. In the prior art, the municipal pipe network system in the city is mainly simulated by hydraulic model software to support more scientific management decisions.

[0003] Traditional hydraulic model software mainly uses stand-alone offline versions of software, such as open-source software epanet and software such as infoworks, waterGEMs, etc. Technical personnel collect data offline and then summarize it into the above-mentioned hydraulic model software. However, in the actual application process, technical personnel found that there are at least the following technical problems:

[0004] The offline use of hydraulic model software is not conducive to the use and coordination of management personnel, thus causing certain troubles to management personnel; the use of offline software results in the inability to interoperate data on multiple platforms, so it is impossible to timely obtain all data in all platforms for pipe network water supply analysis, resulting in deviations in pipe network water supply control, and there are also technical problems such as high data monitoring costs and complex software operations.

[0005] On the other hand, traditional hydraulic simulation software often uses a fixed hydraulic model for management. However, different hydraulic environments may require different hydraulic models for accurate management, resulting in very poor compatibility of traditional hydraulic simulation software, which requires targeted individual development, causing great pressure on enterprises, reducing the software usage efficiency, and unable to meet actual needs.

[0027] First, the background technology of the present invention is introduced below.

[0028] Existing municipal pipe network hydraulic models are often stand-alone offline versions developed many years ago, which meet the initial planning requirements of previous municipal pipe networks. However, with the development of the economy and the change of actual needs, traditional hydraulic models cannot meet higher requirements, such as the later planning requirements of municipal pipe networks, the multi-platform data docking requirements, and the real-time analysis requirements of the water supply pipe network status, etc.

[0029] To solve the above technical problems, please refer to Figure 1 , the embodiments of the present invention provide a real-time update method for a municipal pipe network monitoring system, and the method includes:

[0030] S10) Determine the municipal pipe network hydraulic model corresponding to the current municipal pipe network monitoring system;

[0031] S20) Configure the water demand parameters of the municipal pipe network hydraulic model to obtain the configured parameters;

[0032] S30) Calculate the real-time water demand data corresponding to the configured parameters;

[0033] S40) Update the control information of the municipal pipe network hydraulic model to obtain the updated control information;

[0034] S50) Update the simulation setting information of the municipal pipe network hydraulic model to obtain the updated simulation settings;

[0035] S60) Update the current municipal pipe network monitoring system in real time based on the real-time updated data, the updated control information, and the updated simulation settings.

[0036] In a possible implementation manner, by building an online monitoring platform, for example, using a web-based terminal based on the B / S architecture to replace the traditional PC client to run the municipal pipe network monitoring system, people are allowed to access and use the hydraulic model of the municipal pipe network anytime and anywhere. At the same time, the data is interconnected to achieve real-time data update and improve the accuracy of the municipal pipe network monitoring system.

[0037] Specifically, during the implementation process, since different places use different hydraulic models, all the functional modules required by the hydraulic models of the municipal pipe network can be pre-integrated into the municipal pipe network monitoring system. When it is necessary to monitor the municipal pipe network in a certain place, the corresponding module can be directly called to quickly generate the update plan of the hydraulic model of the municipal pipe network.

[0038] For example, in the embodiment of the present invention, when establishing a monitoring system for the municipal pipe network in a certain place, the hydraulic model of the municipal pipe network corresponding to the current water supply pipe network monitoring system is determined. Specifically, the monitoring system includes a real-time update module, a hydraulic simulation module, a water quality simulation module, and a system management module. Through the real-time update module, real-time monitoring of the water usage data of the entire monitored municipal pipe network system can be achieved. Through the hydraulic / water quality simulation module, hydraulic / water quality simulation monitoring can be carried out. Through the system management module, other functions can be achieved, such as the function of visualizing the real-time updated data, the function of managing the management personnel, etc. In the specific application process, through configuring each parameter of the hydraulic model of the municipal pipe network and combining the collected real-time hydraulic data, the real-time and accurate update of the monitoring system can be achieved.

[0039] In the actual application process, the traditional water supply pipe network monitoring system often configures the parameters of the entire monitoring area as a whole after collecting some monitoring data and performs overall data update (each node in the entire monitoring area is updated using the same scaling factor or update method), resulting in inaccurate monitoring data and unable to meet the actual needs.

[0040] To solve the above technical problems, please refer to Figure 2 , in the embodiment of the present invention, the configuration of the water demand parameters of the hydraulic model of the municipal pipe network to obtain the configured parameters includes:

[0041] S21) Obtain the water demand parameters of all nodes in the hydraulic model of the municipal pipe network;

[0042] S22) Perform a water supply point parameter configuration operation on the water demand parameters to generate the first configured parameters;

[0043] S23) Perform a constant flow point parameter configuration operation on the first configuration parameter to generate a second configuration parameter;

[0044] S24) Perform a parameter configuration operation on the second configuration parameter data based on the large user update condition to generate a third configuration parameter;

[0045] S25) Perform a parameter configuration operation on the third configuration parameter based on the metering area update condition to generate the configured parameter.

[0046] In a possible implementation manner, first configure the time parameter of the municipal pipe network hydraulic model. Specifically, set the model calculation time of the municipal pipe network hydraulic model to single-moment calculation. Of course, other time settings can also be adopted according to the actual situation, which is not limited here. Then configure the water demand parameters of each node. Specifically, first obtain the water demand parameters of all nodes in the current municipal pipe network hydraulic model, and then determine whether a feed water point update is required. If so, determine whether the above nodes contain a feed water point. If a feed water point is included, delete the feed-in point flow data and the feed-out point flow data corresponding to the feed water point in the water demand parameters to generate a first configuration parameter;

[0047] At this time, determine whether a constant flow point update is required. If so, determine whether the above nodes contain a constant flow point. If a constant flow point is included, delete the constant flow pipe section flow data corresponding to the constant flow point in the first configuration parameter to generate a second configuration parameter; then determine whether a large user update is required. If so, read the large user list and the large user data (pre-configured), and perform a validity check on the large user data. For example, if a certain large user node has no real-time data, include this node in the ordinary nodes, and then generate a corresponding large user node list and large user real-time flow data according to the valid large user nodes. During the parameter configuration process, delete the above large user real-time flow data to generate a third configuration parameter.

[0048] At this time, it is further determined whether it is necessary to update the District Metering Area (DMA). If it is necessary to update the DMA in real time, the DMA list is read through a pre-configured file, and the regional flow data of each partition is calculated in real time. In order to improve the accuracy of the DMA data, the validity of the regional flow data is further verified. For example, if the regional flow data of a certain area is non-positive or non-integer, the regional flow data of this area is considered invalid data. At this time, the area corresponding to the valid data is used as the valid area, and the area corresponding to the invalid data is used as the invalid area. In the specific implementation process, if there is no valid area, all invalid areas are merged into a whole invalid area. If there are valid areas, a corresponding valid area list (including at least one valid area) is sorted out. At the same time, if there is at least one invalid area, all invalid areas are integrated into a whole invalid area. According to the hydrological data collected in real time, the valid real-time flow data of each valid area can be obtained, and the invalid real-time flow data of the whole invalid area can be obtained according to the total water demand data of the pipe network combined with the above valid real-time flow data.

[0049] In the actual application process, since the DMA is only a physical area artificially set for the convenience of management, and the water demand parameters may span different DMAs, the water demand parameters in the DMA may not match the water demand parameter settings in the hydraulic model, resulting in the situation that the water demand parameters in a certain DMA also exist in another DMA. In the subsequent real-time data update process, if the same water demand parameter in two DMAs is modified and updated respectively, there will be a situation of repeated modification and update, resulting in the mutual influence of the parameters in the two DMAs and ultimately leading to data deviation.

[0050] To solve the above technical problems, after obtaining the above valid DMA list and the corresponding valid real-time flow data and / or invalid DMA and the corresponding invalid real-time flow data, the node parameters in each DMA are copied and renamed to obtain the renamed node parameters. The name of each renamed node parameter corresponds to the area where it is located. That is, through the above renaming operation, the node parameters in each DMA are unique in the entire municipal pipe network monitoring system, and the situation of repeated update of the same parameter will not occur in the subsequent data update process, thus effectively solving the above technical problems.

[0051] It should be noted that in the above parameter configuration process, the parameter configuration processes for the water feeding point, fixed flow point, large user, and DMA are the corresponding processes in the parameter configuration of the municipal pipe network hydraulic model. Technical personnel can adjust the parameter configuration order according to actual needs or configure all parameters at the same time. The implementation of the above steps is only a specific implementation method of the embodiments of the present invention and does not limit the order of the configuration process. Therefore, no more details will be elaborated here.

[0052] Through the above parameter configuration operation, the accurate configuration of all node parameters in the municipal pipe network hydraulic model is achieved, and the corresponding post-configuration parameters are obtained. In the subsequent data update process, real-time and accurate update of the entire municipal pipe network monitoring system can be realized by updating the data in the above post-configuration parameters in real time.

[0053] Please refer to Figure 3 , calculating the real-time water demand data corresponding to the post-configuration parameters, including:

[0054] S31) Obtain the inflow and outflow data of the current hydraulic monitoring area in real time, and calculate the corresponding real-time total water demand data of the pipe network based on the inflow and outflow data;

[0055] S32) Perform a feed point data update operation on the post-configuration parameters based on the real-time hydraulic sensing data to generate real-time feed point data;

[0056] S33) Perform a fixed flow point data update operation on the post-configuration parameters based on the real-time hydraulic sensing data to generate real-time fixed flow point data;

[0057] S34) After generating the real-time feed point data and the real-time fixed flow point data, if the post-configuration parameters include large user update parameters, perform a large user data update operation on the large user update parameters based on the real-time hydraulic sensing data to generate real-time large user data;

[0058] S35) After generating the real-time large user data, perform an independent area parameter update operation based on the real-time large user data to generate real-time water demand data.

[0059] In a possible implementation manner, after configuring the water demand parameters in the municipal pipe network hydraulic model, a real-time data update operation is performed. First, calculate the real-time total water demand data of the pipe network according to all the inflow and outflow data of the current hydraulic monitoring area, and then perform a feed point data update operation on the post-configuration parameters based on the real-time hydraulic sensing data to generate real-time feed point data. Specifically, determine whether there is a feed point in the post-configuration parameters. If it is included, update the feed point data according to the real-time hydraulic sensing data. For example, the feed points include the feed-in point and the feed-out point. Set the basic water volume of the feed-in point to -1 and the basic water volume of the feed-out point to 1. At this time, the real-time data of the feed-in point is -1 * the real-time hydraulic sensing data of the feed-in point, and the real-time data of the feed-out point is 1 * the real-time hydraulic sensing data of the feed-out point, that is, the real-time feed point data is obtained; and perform a fixed flow point data update operation to generate real-time fixed flow point data. Specifically, determine whether the configuration parameters include a fixed flow point. If it is included, set the basic water demand of the fixed flow point to -1, that is, the real-time fixed flow point data is -1 * the real-time hydraulic sensing data of the fixed flow point.

[0060] It should be noted that the update of the feed water point and constant flow point data may not have a sequential order. The above embodiments are only specific examples and do not limit the order of the above data update. Those skilled in the art can adjust or set according to actual needs and will not be elaborated here.

[0061] After obtaining the real-time feed water point data and real-time constant flow point data of the entire municipal pipe network monitoring system, the large user data update can be further carried out. Specifically, it is judged whether the large user data needs to be updated. If so, the basic water demand parameter of each large user node is set to 1, that is, the real-time large user data is 1 * the real-time hydraulic sensing data of the large user node. At this time, it is further judged whether the DMA update is needed. If so, the total water volume data of the ordinary nodes in the DMA is calculated in real time based on the real-time large user data. Specifically, the total water volume data of all ordinary nodes in the DMA is obtained by subtracting the real-time large user data in the DMA from the real-time water volume data of the DMA. Specifically, the first total water volume data of the ordinary nodes included in all effective regions is calculated by using the independent region sensing data and the real-time large user data. The total water volume data of all ordinary nodes in the invalid region is obtained by subtracting all effective region sensing data and the real-time large user data in all invalid regions from the real-time total water demand data of the pipe network. Then, the first historical total water volume data of the ordinary nodes in the above DMA is obtained, and the first scaling coefficient corresponding to the current DMA is generated according to the above two data. For example, the first scaling coefficient = total water volume data of regional ordinary nodes / first historical total water volume data of ordinary nodes. At this time, the historical water volume data of all ordinary nodes in each effective region and / or invalid region is adjusted in real time according to the first scaling coefficient to generate the real-time water demand data of each ordinary node; if the DMA update is not required, the total water volume data of all ordinary nodes is calculated in real time based on the real-time total water demand data of the pipe network and the real-time large user data, and the second historical total water volume data of each ordinary node is obtained. The second scaling coefficient of all ordinary nodes can be calculated according to the total water volume data of the ordinary nodes and the second historical total water volume data of the ordinary nodes.

[0062] Specifically, during the calculation process, first, it is determined whether the configured parameters include large user parameters. If so, to ensure the accuracy of large user data calculation, it is first necessary to perform validity verification on the real-time large user data. For example, data less than 0 or non-integer data can still be regarded as invalid large user data, thereby obtaining valid large user data and invalid large user data. Then, the nodes corresponding to the invalid large user data are used as ordinary nodes. Of course, it is easy for those skilled in the art to understand that the validity verification of large user data can be performed according to actual needs when updating large user data. At this time, the real-time total water volume data of ordinary nodes is calculated based on the obtained real-time total water demand data of the pipe network and the valid large user data. For example, the real-time total water volume data of ordinary nodes = real-time total water demand data of the pipe network - valid large user data. Then, the second scaling factor of the ordinary nodes is calculated. For example, this second scaling factor = real-time total water volume data of ordinary nodes / real-time total water demand data of the pipe network. On the other hand, if the large user parameters are not included, the historical total water volume data of the system is directly obtained, and the second scaling factor is calculated based on the total water demand data of the pipe network and the historical total water volume data of the system. For example, this second scaling factor = total water demand data of the pipe network / historical total water volume data of the system. At this time, the real-time water demand data of all nodes in the DMA is updated in real time according to the second scaling factor, and the real-time water demand data of all nodes is further generated in combination with the real-time water volume sensing data.

[0063] In the embodiment of the present invention, during the data update process, considering the actual situation under different municipal pipe network hydraulic models, all nodes are accurately configured and updated to achieve real-time update of each ordinary node. At the same time, combined with the settings of large users and DMA, further accurate data update on the basis of all ordinary nodes is realized, meeting the actual needs and improving the user experience.

[0064] After the water demand parameter is updated in real time and the real-time water demand data is obtained, the control information of the municipal water supply network hydraulic model is further updated. In the embodiment of the present invention, the control information includes the control information of the pump station inlet valve, the control information of the pump station outlet valve, the control mode information of the constant-speed pump, the control mode information of the variable-frequency pump, and the control mode information of the water level of the water plant and the pump station pool. The updating of the control information of the municipal water supply network hydraulic model to obtain the updated control information includes: updating the control information of the pump station inlet valve to obtain the updated inlet valve control information, updating the control information of the pump station outlet valve to generate the updated outlet valve control information, updating the control mode information of the constant-speed pump to generate the updated constant-speed pump mode information, updating the control mode information of the variable-frequency pump to generate the updated variable-frequency pump mode information, and updating the control mode information of the water level of the water plant and the pump station pool to generate the updated water level mode information; and using the updated inlet valve control information, the updated outlet valve control information, the updated constant-speed pump mode information, the updated variable-frequency pump mode information, and the updated water level mode information as the updated control information.

[0065] Then, the simulation setting information of the municipal water supply network hydraulic model is updated, and the updated simulation setting is obtained. For example, the setting of the constant-pressure and constant-flow simulation is updated. Finally, the current municipal water supply network monitoring system is updated in real time based on the above real-time updated data, the updated control information, and the updated simulation setting, thereby realizing the real-time monitoring of the water supply network.
