[0002] With the rapid development of industrial automation and intelligent technology, variable frequency water pumps, as key equipment for fluid transmission and control, have been widely used in water supply, drainage, HVAC and other fields. However, traditional water pump control systems have many shortcomings, including: traditional methods rely on manual input of equipment information, which is prone to errors and inefficient. Network establishment and address allocation: The network establishment in the existing technology is complex, and address allocation is prone to conflict. Control instruction synchronization: In traditional control systems, the synchronization of control instructions is poor, which affects the overall performance of the system. Real-time monitoring and fault handling: The existing system does not monitor the operating status of the water pump comprehensively, and the fault response is not timely. These problems not only affect the operating efficiency of the water pump system, but also increase maintenance costs and downtime risks. Summary of the invention

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0098] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0099] like Figure 1As shown, a control method for a water pump ad hoc network includes the following steps:

[0100] Step S1: using radio frequency identification technology or two-dimensional code scanning to obtain the unique identity of each variable frequency water pump;

[0101] Step S2: According to the acquired unique identification of the variable frequency water pump, the configuration information of each variable frequency water pump is identified, including but not limited to the model, specification and performance parameters;

[0102] Step S3: The control system determines whether each identified variable frequency water pump is suitable for the current control strategy or networking requirements. If so, step S4 is executed; if not, modification suggestions are provided or individual configuration adjustments are made through the user interface or remote management platform;

[0103] Step S4: using Bluetooth mesh, Zigbee or other wireless communication technologies, the variable frequency water pumps that meet the control strategy requirements are automatically formed into a control network, and a unique network address is assigned to each water pump;

[0104] Step S5: In the control network, control parameters of any variable frequency water pump are set, and the set parameters are automatically distributed to other water pumps in the same control network through the network synchronization mechanism;

[0105] Step S6: The control system monitors the operating status of each water pump in real time, including but not limited to the motor current, voltage, temperature, and motor efficiency and load conditions estimated by intelligent algorithms; when abnormal parameters are detected, the control system automatically adjusts the control parameters, issues early warning signals, or isolates the faulty water pump according to a preset fault handling strategy to maintain the stable operation of each water pump.

[0106] Specifically, steps S1 and S2 use radio frequency identification technology (RFID) or QR code scanning to quickly and accurately obtain the unique identity of each variable frequency water pump and the corresponding variable frequency water pump configuration information, such as model, specifications and performance parameters, to provide a basis for subsequent adaptability judgment and control strategy formulation.

[0107] In step S3, the control system determines whether the identified variable frequency water pump meets the conditions according to the current control strategy or networking requirements. If not, it provides modification suggestions to the administrator through the user interface or remote management platform, or directly adjusts the configuration of individual water pumps to ensure that all water pumps can adapt to the current control environment.

[0108] Step S4 uses wireless communication technologies such as Bluetooth mesh and Zigbee to automatically form a control network for variable frequency water pumps that meet the control strategy requirements. A unique network address is assigned to each water pump in the network to achieve seamless communication between devices and ensure the accuracy and real-time nature of data transmission.

[0109] Step S5 sets the control parameters (such as speed, flow rate, etc.) of any water pump in the control network. And through the network synchronization mechanism, these setting parameters are automatically distributed to other water pumps in the same control network to ensure that the control instructions of all water pumps are consistent, thereby improving the overall coordination and response speed of the system.

[0110] Step S6 monitors the operating status of each pump in real time through the control system, including key parameters such as motor current, voltage, and temperature. It also uses intelligent algorithms to estimate the efficiency and load conditions of the motor to detect potential problems in a timely manner. When abnormal parameters are detected, corresponding operations are automatically performed according to the preset fault handling strategy, such as adjusting control parameters to optimize performance, issuing early warning signals to notify administrators, or isolating faulty pumps to prevent the spread of faults, thereby maintaining the stable operation of the system.

[0111] In summary, the present invention significantly improves the control efficiency, flexibility and intelligence level of the multi-frequency water pump system through non-traditional identification methods, intelligent monitoring, adaptive adjustment and self-learning optimization mechanisms, and brings a new solution to the field of fluid control.

[0112] To further illustrate, step S2 specifically includes the following sub-steps:

[0113] Step S21: establishing a variable frequency water pump database, wherein the variable frequency water pump database includes configuration information corresponding to unique identifications of a number of variable frequency water pumps;

[0114] Step S22: searching and matching in the variable frequency water pump database according to the acquired unique identity of the variable frequency water pump;

[0115] Step S23: Acquire configuration information corresponding to the unique identification number of the variable frequency water pump from the variable frequency water pump database.

[0116] In this embodiment, by establishing a variable frequency water pump database, it is convenient to manage and store the model information corresponding to the unique identity identifiers of several variable frequency water pumps, which is conducive to the identification of the variable frequency water pump models.

[0117] To further illustrate, step S3 specifically includes the following sub-steps:

[0118] Step S31: Verify the compatibility of the water pump model with the current control strategy: Check whether the water pump model supports the functions required by the current control strategy, including but not limited to variable frequency speed regulation and remote communication;

[0119] Step S32: Evaluate whether the performance parameters of the water pump meet the requirements: compare whether the rated flow, head, and power of the water pump match the preset requirements; ensure that the water pump can operate stably under the expected working conditions.

[0120] Step S33: Check the maintenance status and history of the water pump: query the database for maintenance records, fault history and the most recent maintenance time of the water pump, and evaluate whether its current health status is suitable for joining the control network;

[0121] Step S34: Based on the above verification and evaluation results, the control system generates a compatibility report, listing all pumps that meet the requirements and pumps that need special attention or adjustment;

[0122] Step S35: Based on the compatibility report, the control system automatically or prompts the user to proceed to the next step, such as adding the water pumps that meet the requirements to the control network, or making individual configuration adjustments, repairs or replacements for the water pumps that do not meet the requirements.

[0123] By expanding the specific content of step S3, a more detailed and comprehensive water pump compatibility verification and evaluation process is provided, ensuring that only water pumps that meet the preset requirements can be included in the control network, thereby further improving the stability and reliability of the water pump control system.

[0124] To further illustrate, in step S35, the following operations are performed on the water pump that does not meet the requirements:

[0125] Step S351: Classify all pumps that do not meet the requirements according to the pump model to obtain multiple type sets; even if there are pumps that do not meet the above requirements, there are still pumps that do not meet the requirements with the same performance parameters, and they still need to be networked. First, classify these pumps that do not meet the requirements into multiple type sets according to the pump model, such as type A pumps, type B pumps, etc.

[0126] Step S352: Searching for the earliest water pump model in the current type set, obtaining the performance parameters of the water pump of the earliest water pump model, searching for a water pump in the type set that can achieve the water pump performance parameters of the earliest water pump model, constructing a control network subnode, and grouping all the searched water pumps into the control network subnode;

[0127] The reason why we look for the earliest water pump type in any type set is that even if they belong to type A water pumps, each generation of water pumps is updated. Finding the earliest water pump type is equivalent to finding the oldest generation of water pumps. Based on this water pump, there will be other updated second-generation and third-generation products. The second and third generations can still realize the functions of the first generation. We need to group all of these into the same network sub-node.

[0128] Step S353: Take other water pumps in the current type set that are not connected to the control network sub-node as a new type set, re-search for the earliest water pump model, and execute the operation of step S352 to build other control network sub-nodes; it should be noted that the first to third generations may be able to access the same sub-node, but after the fourth generation, although the type is the same, the performance has been greatly improved and the performance parameters of the first three generations are no longer supported. These require the third generation to be taken as the earliest model and the operation of step S352 to be re-executed.

[0129] Step S354: Execute the operations of step S352 and step S353 on the water pumps in all types of sets, and obtain multiple control network sub-nodes;

[0130] Step S355: retaining the control network sub-node with only one water pump connected or removing the control network sub-node with only one water pump connected according to demand, and repairing or replacing the removed water pump;

[0131] After steps S352 and S353 are executed, there will definitely be some independent water pumps that are not supported. These water pumps can be given a network sub-node separately or fed back to the user interface or remote management platform for the user or administrator to decide to delete, repair or replace them.

[0132] Step S356: construct a new control network, connect multiple control network sub-nodes to the new control network, configure a coordinator, and the new control network can be connected to the control network where the water pump that meets the requirements is located through the coordinator.

[0133] The new control network can be understood as a network connected to the non-compliant water pumps. It needs to be able to connect to the network of the compliant water pumps, and at the same time be independent. The coordinator can achieve this effect. The user of the user interface or the administrator of the remote management platform can choose whether to connect through the coordinator. If connected, the non-compliant control network can be operated through the compliant control network. If not connected, the sub-nodes below need to be controlled separately through the non-compliant control network.

[0134] To further illustrate, step S6 specifically includes the following sub-steps:

[0135] Step S61: real-time monitoring of the operating status of each water pump, including but not limited to key parameters of motor current I, voltage V, temperature T, flow rate Q and head H;

[0136] Step S62: estimating motor efficiency and load conditions through intelligent algorithms based on key parameters;

[0137] Step S621: input power Pin=V×I;

[0138] Step S622: output power Pout = ρ×g×H×Q / 3600; wherein ρ is the fluid density and g is the gravitational acceleration;

[0139] Step S623: electrical efficiency η1 = Pin / Pout×100%;

[0140] Step S624: The electrical efficiency loss Lossη is obtained by one or a combination of the following calculations:

[0141] Lossη=(η2-η1) / η2×100%; where η2 is the rated electrical efficiency;

[0142] Lossη=(η3-η1) / η3×100%, where η3 is the historical average electrical efficiency;

[0143] Step S625: Mechanical loss assessment is performed through comprehensive analysis of vibration analysis, temperature monitoring and sound detection;

[0144] Among them, vibration analysis identifies abnormal vibration frequencies through spectrum analysis and evaluates the health of components such as bearings and impellers;

[0145] Temperature monitoring: By monitoring the temperature of the motor and key components and comparing them with preset thresholds, it can assess heat loss and potential mechanical wear.

[0146] Sound detection evaluates the operating status of mechanical parts by detecting abnormal noise through sound sensors;

[0147] S63: When abnormal parameters (such as excessive current, excessive temperature, abnormal vibration, etc.) are monitored in real time or the electrical efficiency loss is estimated to exceed the preset threshold, the control system will automatically perform one or a combination of the following operations:

[0148] S641: Adjust the variable frequency control parameters of the water pump to optimize operating efficiency and energy consumption;

[0149] S642: Send out a warning signal to notify the operator to pay attention or intervene;

[0150] S643: Automatically isolate the faulty water pump and start the backup water pump to maintain stable operation of the system.

[0151] Through real-time monitoring, intelligent analysis and optimized control in step S6, precise control and efficient operation of the water pump system are achieved, while the reliability and maintenance efficiency of the control system are improved.
