Description

A smart valve control system Technical Field

[0001] This invention relates to the field of valve control technology, specifically to an intelligent valve control system. Background Technology

[0002] A smart valve control system is a system that utilizes advanced technology and intelligent algorithms to control valves. It can monitor and control the opening and closing of valves, as well as regulate valve flow and pressure. A smart valve control system typically consists of sensors, actuators, controllers, and a human-machine interface (HMI). In a smart valve control system, sensors are used to perceive environmental and fluid parameters, such as temperature, pressure, and flow rate. The controller determines the valve's state and position based on sensor data and preset control strategies. The actuators are responsible for the actual control of the valve's opening, closing, and regulation. The HMI provides a monitoring and control interface for the system, allowing operators to intuitively understand the system's operating status and make necessary adjustments and settings. The advantages of a smart valve control system include precise control, remote monitoring and operation, and adaptive regulation. It can be applied to various fields, such as industrial production, energy systems, and water and gas supply systems, improving system efficiency and safety while saving energy and resource consumption.

[0003] Intelligent valve control systems can also be applied to the following areas: Automated process control: Intelligent valve control systems can be integrated with other equipment and systems to achieve automated process control. For example, in industrial production, intelligent valve control systems can automatically adjust flow and pressure, optimize the production process, and improve product quality and efficiency. Remote monitoring and operation: Intelligent valve control systems can achieve remote monitoring and operation through network connections. This means that operators can remotely monitor the status and parameters of valves from anywhere and make necessary adjustments and controls.

[0004] This remote operation and monitoring capability can greatly improve operational flexibility and efficiency, reducing the need for human resources. Fault warning and maintenance: The intelligent valve control system can provide fault warnings and maintenance prompts through real-time monitoring and data analysis. For example, when a valve's operating status is abnormal or a failure is imminent, the system can issue an alarm in a timely manner and provide relevant diagnostic information to help operators take appropriate measures to avoid system failures and downtime losses. Energy saving and environmental protection: The intelligent valve control system can achieve energy conservation and environmental protection by optimizing fluid flow and pressure. For example, in a water supply system, the intelligent valve control system can adjust the water flow according to demand, avoiding waste and leakage, and achieving water conservation. The intelligent valve control system has broad application prospects in industrial and public facilities fields, improving system control accuracy and reliability, enhancing operational convenience and efficiency, and achieving energy saving and environmental protection goals.

[0005] Most existing intelligent valve control systems are process control systems that provide precise control and remote operation. However, the maintenance cost of the pipelines within the system is high, and the failure or damage of components can easily lead to system paralysis. Therefore, they do not meet the current needs. In response, we propose an intelligent valve control system. Summary of the Invention

[0006] This invention provides an intelligent valve control system in which the upstream and downstream pipes are connected through two identical sub-valve systems. Even if one sub-valve system fails, the other sub-valve system can still operate normally.

This has the beneficial effects of saving maintenance costs and improving the reliability and performance of the valve control system.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0092] Example 1: This example aims to address the problem that most existing smart valve control systems are process control systems that focus on precise control and remote operation, but the maintenance costs of the pipelines within the system are high, and the failure or damage of components within the system can easily lead to system paralysis. Please refer to Figures 1-4. A smart valve control system includes: an upstream pipe and a downstream pipe, which are connected through a valve system.

[0093] The valve system includes two identical sub-valve systems. The upstream pipe and the downstream pipe are connected through the two sub-valve systems, and the two sub-valve systems are connected in parallel. Each sub-valve system specifically includes: a first target pipe, wherein one end of the first target pipe is connected to the upstream pipe, and the other end of the first target pipe is connected to a third target pipe. The first target pipe is equipped with a first target valve for opening and closing the first target pipe.

[0094] The second target pipeline has one end connected to the downstream pipeline and the other end connected to the fourth target pipeline. The second target pipeline is equipped with a second target valve for opening and closing the second target pipeline.

[0095] The third target valve is used to open and close the flow of the third target pipeline and the fourth target pipeline; the third target pipeline is connected to the third target valve at the other end, and the fourth target valve is provided on the third target pipeline for opening and closing the flow of the third target pipeline.

[0096] The fourth target pipeline has its other end connected to the third target valve, and a fifth target valve is provided on the fourth target pipeline for opening and closing the flow of the fourth target pipeline.

[0097] The unblocking module is used to backflush the filtration system inside the third target valve. The unblocking module specifically includes: a fifth target pipe, wherein one end of the fifth target pipe is connected to the third target pipe to form a first connection node, and the fourth target valve is located between the first connection node and the filtration system; the other end of the fifth target pipe is connected to the fourth target pipe to form a second connection node, and the second connection node is located between the fifth target valve and the third target valve; a sixth target valve for opening and closing the fifth target pipe is provided on the fifth target pipe.

[0098] The sixth target pipeline has one end connected to the third target pipeline to form a third connection node, and the third connection node is located between the fourth target valve and the filtration system. The other end of the sixth target pipeline is connected to the fourth target pipeline to form a fourth connection node, and the fifth target valve is located between the fourth connection node and the third target valve. The sixth target pipeline is equipped with a seventh target valve for opening and closing the sixth target pipeline.

[0099] The filtration system includes a first filtration module and a second filtration module. The first filtration module has one end connected to a third target pipeline and is located between the third target valve and the first connection node. The first filtration module is equipped with a first filter and a second filter for filtering the liquid in the first module.

[0100] The second filter module has one end connected to the fourth target pipeline and is located between the third target valve and the second connection node. The second filter module has the same structure as the first filter module.

[0101] A storage module is used to store impurities filtered by the filtration module. The storage module specifically includes: a first target storage box, wherein one end of the first target storage box is connected to the filtration module to form a fifth connection node, and the fifth connection node is located between the first filter and the second filter; an eighth target valve for opening and closing the first target storage box is provided on the first target storage box, and a third filter for filtration is provided on the side of the first target storage box.

[0102] The seventh target pipeline has one end connected to the side of the first target storage box and the other end connected to the sixth target pipeline; the seventh target pipeline is equipped with a ninth target valve for opening and closing the seventh target pipeline.

[0103] In this embodiment: the upstream and downstream pipes of the system are connected through two identical sub-valve systems. Even if one sub-valve system fails, the other sub-valve system can still operate normally. At the same time, the setting of multiple target pipes and valves also provides the possibility of backup and replacement to deal with component failure or damage. It also includes a filtration module, in which the filter can filter the liquid and remove impurities and contaminants. There is also a dredging module for backflushing the filtration system in the third target valve, reducing filter clogging and wear, reducing the frequency of maintenance and filter replacement, saving maintenance costs, and improving the reliability and performance of the valve control system.

[0104] Example 2 aims to address the problem of clogging caused by excessive impurities in the filtration system. This example is an improvement upon Example 1. Specifically, please refer to Figures 1-4. The pressure monitoring module is used to monitor the pressure of the liquid flow through the target area in real time. The pressure monitoring module can sense the water pressure in the water supply system in real time through sensors or pressure transmitters. It collects pressure data periodically or continuously.

[0105] Turbidity monitoring module: Used to measure the turbidity of liquids in real time. The turbidity monitoring module senses the turbidity of water in the water supply system in real time through sensors or turbidity instruments, and continuously measures the particulate matter in the water sample to determine the turbidity level.

[0106] The processing module is used to process the data information acquired in the pipeline. The processing module monitors the real-time changes in the water quality through sensors. When it detects abnormal situations that exceed the set threshold, it will take relevant countermeasures based on the abnormal situation, providing a reference for the optimization and adjustment of the system.

[0107] Control module: By processing the signals sent by the module, it controls the opening and closing of valves to regulate the water flow in the pipeline and realize the flow control and distribution of the water supply system.

[0108] Acquire target monitoring information for the target area, analyze whether any anomalies occur within the target area, and generate anomaly signals. Specifically, the target area consists of the first target pipeline and the second target pipeline; the target monitoring information includes target flow data in the first target pipeline and the target flow data in the second target pipeline; and the target flow data is the real-time liquid pressure data for the target area.

[0109] The target flow data specifically includes the first target flow rate Q1 located in the first target pipeline and the second target flow rate Q2 located in the second target pipeline; for example, the first target flow rate Q1 is 0.7 MPa and the second target flow rate Q2 is 0.4 MPa.

[0110] Calculate the first target flow difference R1, where R1 = first target flow Q1 - second target flow Q2. For example, if the first target flow difference R1 is 0.7 - 0.4 = 0.3 MPa;

[0111] Set a first flow threshold E1, for example, set the first flow threshold E1 to 0.2 MPa;

[0112] Compare the first target flow difference R1 with the first flow threshold E1; if 0.3 MPa is greater than 0.2 MPa, then the first target flow difference R1 is greater than the first flow threshold E1, and the first abnormal strategy is executed.

[0113] The first abnormal strategy is as follows: the control module closes the fourth and fifth target valves and opens the sixth and seventh target valves in the unblocking module; the liquid enters the fifth target pipe from the third target pipe, and then enters the third target valve from the fifth target pipe, and uses the flow and pressure of the liquid to flush the filter module in the filtration system.

[0114] Get the third target flow Q3 in the first target pipeline in the execution of the first abnormal strategy; get the fourth target flow Q4 in the second target pipeline in the execution of the first abnormal strategy; calculate the second target flow difference R2, the second target flow difference R2 = third target flow Q3 - fourth target flow Q4; set the second flow threshold E2, such as the second flow threshold E2 is 0.1 MPa.

[0115] Compare the second target flow difference R2 with the second flow threshold E2; if the third target flow Q3 is 0.7 MPa and the fourth target flow Q4 is 0.6 MPa, the second target flow difference R2 is 0.7-0.6=0.1 MPa. The second target flow difference R2 is equal to the second flow threshold E2, so continue to execute the current strategy.

[0116] If the third target flow rate Q3 is 0.7 MPa, the fourth target flow rate Q4 is 0.4 MPa, and the second target flow rate difference R2 is 0.7 - 0.4 = 0.3 MPa, and the second target flow rate difference R2 is greater than the second flow rate threshold E2, then the initial strategy is executed.

[0117] The initial strategy is as follows: the sixth and seventh target valves in the unblocking module are closed by the control module, and the fourth and fifth target valves are opened; the liquid enters the third target valve from the third target pipeline, and then enters the fourth target pipeline from the third valve.

[0118] Get the fifth target flow Q5 in the first target pipeline in the execution of the initial anomaly strategy, such as: the fifth target flow Q5 is 0.7 MPa; get the sixth target flow Q6 in the second target pipeline in the execution of the initial anomaly strategy, such as: the sixth target flow Q6 is 0.6 MPa.

[0119] Calculate the third target flow difference R3. The third target flow difference R3 = the fifth target flow Q5 - the sixth target flow Q6. If the third target flow difference R3 is 0.7 - 0.6 = 0.1 MPa, then the third target flow difference R3 is equal to the second flow threshold E2, and the current strategy continues to be executed.

[0120] In this embodiment, by setting a third module for backflushing the filtration system within the third target valve, impurities and blockages on the filter screen can be removed by high-pressure water jets when the filter screen becomes clogged, restoring the filter screen's filtration capacity. Regular backflushing of the filter screen can effectively extend its service life. Removing dirt and impurities from the filter screen through backflushing reduces clogging and wear, lowers the frequency of filter screen repair and replacement, and saves maintenance costs.

[0121] Example 3: This example aims to help solve the problem of pipe damage or filter breakage in the system. This example is an improvement on Example 1. Specifically, please refer to Figures 1-4. If the fifth target flow rate Q5 is 0.7 MPa, the sixth target flow rate Q6 is 0.4 MPa, and the third target flow rate difference R3 is 0.7-0.4=0.3 MPa, the third target flow rate difference R3 is greater than the second flow rate threshold E2, and the third abnormal strategy is executed.

[0122] The third abnormal strategy is as follows: perform pipeline maintenance on the sub-valve system. If a pipeline problem occurs in the sub-valve system, close the first target valve and the second target valve through the control module, activate another sub-valve system, and perform problem repair on the sub-valve system.

[0123] If no pipeline problem occurs in the valve system, the fourth abnormal strategy is executed. The fourth abnormal strategy is as follows: obtain the first turbidity U1 in the first target pipeline; obtain the second turbidity U2 in the second target pipeline; calculate the first target turbidity difference P1, where the first target turbidity difference P1 = second turbidity U2 - first turbidity U1; set the first turbidity threshold A1, such as the first turbidity threshold A1 being 6 NTU.

[0124] Compare the first turbidity threshold A1 with the first target turbidity difference P1; if the first turbidity U1 is 20 NTU and the second turbidity U2 is 18 NTU, then the first target turbidity difference P1 is 20-18=2 NTU. If the first turbidity threshold A1 is greater than the first target turbidity difference P1, the first target valve and the second target valve need to be closed through the control module, another branch valve system needs to be activated, and the branch valve system needs to be inspected.

[0125] If the first turbidity U1 is 20 NTU and the second turbidity U2 is 13 NTU, then the first target turbidity difference P1 is 20-13=7 NTU. The first turbidity threshold A1 is less than the first target turbidity difference P1, so the fifth abnormal strategy is executed.

[0126] The fifth abnormal strategy is as follows: the eighth target valve is opened through the control module, and the liquid and impurities enter the storage module; the ninth target valve is opened through the control module, and the liquid enters the seventh and sixth target pipelines through the third filter, and then enters the fourth target pipeline through the sixth target pipeline. Finally, the liquid flows into the second target pipeline through the fourth target pipeline.

[0127] Obtain the first abnormality count N and the initial strategy M of the valve system; calculate the filtering count H of the valve system, where H = first abnormality count N + initial strategy M; set the filtering threshold F, for example, set the filtering threshold F to 9 times.

[0128] Compare the number of filtrations H of the valve system with the filtration threshold F; if the first abnormality count N is 3 times, the initial strategy M is 4 times, and the number of filtrations H is 3+4=7 times, then the number of filtrations H of the valve system is less than the filtration threshold F, and the current strategy continues to be executed.

[0129] If the first abnormality count N is 4 times, the initial strategy M is 5 times, and the number of filters H is 4+5=9 times, then the number of filters H of the sub-valve system is equal to the filter threshold F; it is necessary to close the first target valve and the second target valve through the control module, start another sub-valve system, and clean up the storage module in the sub-valve system.

[0130] In this embodiment: the pressure monitoring module and turbidity monitoring module can monitor the pressure and turbidity information of the liquid flow rate in real time; by analyzing the monitoring information in the target area, the system generates anomaly signals, and detects and handles pipeline system anomalies in a timely manner according to different anomaly situations, ensuring the safe, reliable and stable operation of the pipeline system; the monitored turbidity data can be used to better clean the storage module, save resources, reduce processing and operating costs, and improve the reliability and performance of the system.
