Description

Technical Field

[0001] This invention relates to the field of water pump system technology, and in particular to a multi-pump system for the renovation of old residential communities. Background Technology

[0002] Current water pump systems are designed for adjustments made to the existing water pipe network, adjusting peak demand accordingly. However, they are not designed for retrofitting older residential areas. Such systems are unsuitable for older pump systems. During the renovation of older residential areas, due to the layout, the old water pipe network sometimes needs to be used, resulting in the addition of new pumps and pipes to the old network. However, due to age and technological advancements, the old network is not fully compatible with the new pump system, leading to decreased hydraulic efficiency. Furthermore, existing pump systems typically adjust peak demand based on the installed water pipe network. In older residential areas, the network is fixed, and the actual carrying capacity after peak adjustment is still affected by the actual working capacity and reliability of the old network, preventing the new pump system from operating at its full potential.

[0003] For example, a "community greywater reuse system and community water supply and drainage system" disclosed in Chinese patent literature, publication number CN107083793B, discloses a system including a water tank and a centralized community water treatment system. The water tank has a water inlet and a greywater outlet. The centralized community water treatment system includes a sedimentation tank, a rapid infiltration sewage treatment device, a water pump, and a storage tank connected in series. However, this solution still has some problems when used in older communities. For example, in older communities, the different load capacities of the pipelines are difficult to control, thus limiting hydraulic efficiency. Summary of the Invention

[0004] To address the problem of limited efficiency in existing pipeline systems in older residential communities, this invention provides a multi-pump system for the renovation of older residential communities. This system adaptively adjusts and controls the water pipeline network of older communities and new pumps, thereby improving water efficiency and reliability.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A multi-pump system for the renovation of old residential areas includes: a first processing module for obtaining waterway reliability information; a second processing module connected to the first processing module, which establishes a new pump model; and a pumping control center connected to the first and second processing modules, which controls the multiple pumps based on the new pump model. The first processing module calculates the reliability of the waterways in the old network: it models the structure of the waterways in the old network to obtain an actual model of the waterways, verifies the reliability of the actual model, and judges the hydraulic condition of the actual model. The second processing module judges the working capacity of the new pumps and calculates their operating parameters. The pumping control center performs coordinated control of the multiple pumps, including both new and old pumps, based on the waterway reliability verification results and the new pump's operating parameters. The addition of new pumps improves hydraulic efficiency, and coordinated control of the multiple pumps through hydraulic reliability verification achieves the allocation control of the old network, improving the reliability of coordinated operation between the new pumps and the old network. This system can adjust the new pumps not only according to the waterway network but also according to the existing old pumps.

[0007] Preferably, the first processing module includes a waterway monitoring submodule, which is connected to a reliability calculation model. The output of the reliability calculation model is connected to the pumping control center. The waterway monitoring submodule monitors parameters such as water flow, pipe wear, pipe load capacity, and network location. The reliability calculation model calculates the reliability of various locations within the network, simulates the load capacity based on water flow, and modifies the simulation results based on influencing parameters such as pipe wear. The modified simulation results are used as input for reliability calculation, incorporating a reliability evaluation mechanism to evaluate the simulated load capacity, thus achieving pipeline reliability calculation. This allows for the determination of pipeline reliability, especially for pipelines in older residential areas with longer service lives, and the determination of the pipeline's adjustable range.

[0008] Preferably, the second processing module includes a new pump sensor that detects the operating parameters of the new pump. The new pump sensor is connected to a second processor, which receives the operating parameters and builds a new pump model. The new pump's power and other operating parameters are determined by the sensor, and its operating efficiency is sent to the second processor for modeling. Building the new pump model includes establishing an operating parameter model and a physical model. The operating parameter model is a working efficiency curve model, and the variables in the working efficiency curve model include working efficiency and working power. By monitoring the new pump through the second processing module, its operating capacity can be determined, enabling real-time monitoring of the new pump when it is integrated into the existing grid and operating alongside existing pumps, thus facilitating real-time adaptive adjustments to the new pump.

[0009] Preferably, the pumping control center includes a multi-pump controller connected to multiple new pumps, with flow controllers installed between the multi-pump controller and each new pump. The multi-pump controller has multiple pumping switches, each individually controlling the operation of one pump. Each pumping switch contains a flow controller that adjusts the flow rate according to preset parameters determined by pipeline wear rate and reliability parameters. This serves as a safety protection mechanism for pumping, preventing pipeline ruptures during pumping and improving pumping reliability.

[0010] Preferably, the waterway monitoring submodule includes a waterway model, in which old pumps and waterway bends are used as nodes, and monitors are installed at some nodes. The pump model is a three-dimensional model, which also includes a network model, in which each edge represents a pipe, and each node represents an old pump and a waterway bend. Monitors are installed at the nodes of the old pumps to monitor the reliability of the nodes. This allows for the monitoring of old pipes and targeted monitoring.

[0011] Preferably, the multi-pump controller includes a comparison circuit. The input terminals of the comparison circuit are a first processing module and a second processing module, respectively. The multi-pump controller is connected to multiple old pumps, and the output terminals of the comparison circuit are connected to a new pump and the old pumps, respectively. The comparison circuit compares the inputs of the first processing module and the second processing module. When the reliability result of the first processing module is greater than the new pump operating parameters of the second processing module, a corresponding signal to strengthen the new pump's operation is output. When the reliability result of the first processing module is less than the new pump operating parameters of the second processing module, a corresponding signal to weaken the new pump's operation is output. This allows the operating parameters of the new pump to be changed according to the actual response effect of the pipeline.

[0012] Preferably, the flow controller includes a power control processor; the processor controls the power and water flow of the new pump, and the processor is connected to a multi-pump controller. The processor receives the reliability calculation results from the first processing module, and establishes gradient flow protection parameters based on the reliability calculation results through gradient sorting, enabling adaptive protection for different pipelines with different reliability levels.

[0013] Preferably, the reliability calculation model includes a hydraulic parameter judgment sub-model and a structural parameter judgment sub-model, which calculate the flow reliability and waterway reliability, respectively. The input to the hydraulic parameter judgment sub-model is hydraulic parameters, determining parameters such as hydraulic efficiency; the input to the structural parameter judgment sub-model is hydraulic parameters and a structural model, determining the stress reliability of the structural model under the current hydraulic parameters. This allows for the determination of the hydraulic efficiency caused by a new pump in the pipeline network and the mechanical effects of that efficiency.

[0014] The present invention has the following advantages:

[0015] (1) By adding new pumps, hydraulic efficiency is improved. By verifying hydraulic reliability, multiple pumps are coordinated and controlled to achieve the allocation and control of the old pipeline network. This improves the reliability of the coordinated operation between the new pumps and the old network. It can adjust the new pumps according to the water pipeline network and also adjust the existing old pumps. (2) The reliability calculation of the pipeline is realized. The reliability of the pipeline, especially the pipelines in old communities with long service time, can be determined, and the adjustable range of the pipeline can be determined. (3) The gradient flow protection parameters are established by gradient sorting based on the reliability calculation results. It can provide adaptive protection for different pipelines with different reliability. It can serve as a safety protection for pumping to avoid pipeline rupture and other situations during pumping, thereby improving pumping reliability. Attached Figure Description

Detailed Implementation

[0024] The following specific embodiments illustrate the implementation of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0025] like Figure 1-4As shown, in a preferred embodiment, the present invention discloses a multi-pump system for the renovation of old residential areas, comprising: a first processing module 1, which obtains water circuit reliability information; a second processing module 2 connected to the first processing module, which establishes a new pump model; and a pumping control center 3 connected to the first and second processing modules, which controls the multiple pumps according to the new pump model. The first processing module calculates the reliability of the water circuit in the old network: it models the structure of the water circuit in the old network to obtain an actual water circuit model, verifies the reliability of the actual water circuit model, and determines the hydraulic condition of the actual water circuit model; the second processing module determines the working capacity of the new pump and calculates the working parameters of the new pump; the pumping control center coordinates the control of the multiple pumps, including both new and old pumps, based on the water circuit reliability verification results and the working parameters of the new pump.

[0026] In use, this invention no longer only regulates peak flow in the pipeline network, such as... Figure 5 Instead of installing an electric valve 53 in the residential area 52, a water pump unit 51 is installed at the electric valve 53; a new control system is established in the water pump system to coordinate the control of the new and old pumps, monitor the reliability of each position in the pipeline in real time, and realize the combined use of the old network and the new pump.

[0027] The first processing module includes a waterway monitoring submodule 12, which is connected to a reliability calculation model 11. The output of the reliability calculation model is connected to the pumping control center. The waterway monitoring submodule monitors parameters such as water flow, pipe wear, pipe load capacity, and network location. The reliability calculation model calculates the reliability of each location in the network, simulates the load capacity based on water flow, and modifies the simulation results based on parameters such as pipe wear. The modified simulation results are used as input for reliability calculation, introducing a reliability evaluation mechanism to evaluate the simulated load capacity, thus achieving pipeline reliability calculation. The waterway monitoring submodule includes a waterway model, with old pumps and waterway bends as nodes, and monitors installed at some nodes. The pump model is a three-dimensional model, which also includes a network model. In the network model, each edge represents a pipe, and each node represents an old pump and waterway bend. Monitors are installed at the nodes of the old pumps to monitor node reliability. This allows for the monitoring of old pipelines and targeted monitoring. The reliability calculation model includes a hydraulic parameter judgment sub-model and a structural parameter judgment sub-model, which calculate the reliability of water flow and the reliability of waterway, respectively. The input of the hydraulic parameter judgment sub-model is hydraulic parameters, which determine parameters such as hydraulic efficiency; the input of the structural parameter judgment sub-model is hydraulic parameters and a structural model, which determine the stress reliability of the structural model under the current hydraulic parameters.

[0028] During use, the first processing module monitors information from the pipeline network, while the water circuit monitoring submodule models the pipeline network inside the old community and performs calculations using a reliability calculation model. For different communities and different pipeline network conditions, monitoring and adjustments can be made to improve the versatility of the multi-pump system.

[0029] The second processing module includes a new pump sensor 21, which detects the operating parameters of the new pump. The new pump sensor is connected to a second processor 22, which receives the operating parameters and builds a new pump model. The new pump's power and other operating parameters are determined by the new pump sensor, and the pump's operating efficiency is sent to the second processor for modeling. Building the new pump model includes establishing an operating parameter model and a physical model. The operating parameter model is a working efficiency curve model, and the variables in the working efficiency curve model include working efficiency and working power. The second processing module monitors the new pump to determine its operating capacity.

[0030] During use, the second processing module monitors the operating information from the new pump and establishes a new pump model.

[0031] The pumping control center includes a multi-pump controller 31, which is connected to multiple new pumps 32. Flow controllers are installed between the multi-pump controller and each of the new pumps. The multi-pump controller has multiple pumping switches, each individually controlling the operation of one pump. Each pumping switch contains a flow controller, which adjusts the flow rate according to preset parameters determined by pipeline wear rate and reliability parameters. The multi-pump controller is also connected to multiple existing pumps 32.

[0032] The multi-pump controller includes a comparison circuit. The input terminals of the comparison circuit are a first processing module and a second processing module, respectively. The multi-pump controller is connected to multiple existing pumps, and the output terminals of the comparison circuit are connected to new pumps and existing pumps, respectively. The comparison circuit compares the inputs of the first and second processing modules. When the reliability result of the first processing module is greater than the new pump operating parameters of the second processing module, it outputs a corresponding signal to strengthen the new pump's operation; when the reliability result of the first processing module is less than the new pump operating parameters of the second processing module, it outputs a corresponding signal to weaken the new pump's operation. The flow controller includes a power control processor. The processor controls the power and water flow of the new pump, and the processor is connected to the multi-pump controller. The processor receives the reliability calculation results from the first processing module and establishes gradient flow protection parameters based on the gradient sorting of the reliability calculation results.

[0033] During use, the pumping control center obtains the operating parameters of the pipeline network and the new pump from the first processing module and the second processing module respectively. It then converts the operating parameters of the two into K values ​​according to the working efficiency conversion relationship, compares the K values ​​to adjust the efficiency of the two, and adjusts the flow rate according to the operating parameters of the new pump. This ensures that the flow rate adjustment is included when adjusting the efficiency, so that the flow rate adjustment does not need to be performed again.

[0034] In the second embodiment, the physical model of the new pump model includes acquiring multiple images of the new pump, performing depth transformation based on the multiple images of the new pump to obtain a three-dimensional model, and then determining a physical model of a certain proportion based on the three-dimensional model.
