DETAILED DESCRIPTION

[0019] The following will clearly and completely describe the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] Please see the attached Figure 1 - Attachment Figure 5 , an embodiment of the present invention provides an automatic control valve opening and closing system, comprising: Main controller module: built-in integrated microprocessor chip, used to receive external command signals and generate corresponding control commands through preset program logic operations; Actuator module: used to receive control commands sent by the main controller module and drive the valve to adjust the angle position parameters of the target object; Detection sensor module: used to collect on-site dynamic data in real time through the sensing terminal and upload it to the main controller module; Redundant backup channel: used to take over control and maintain the system's minimum basic functions when the main controller module or actuator unit fails.

[0021] Specifically, the main controller module has an integrated microprocessor chip built into it, which receives instructions from managers and performs calculations based on preset program logic, converting the received instructions into specific control commands, thereby guiding the various parts of the system to work together, ensuring that the system performs tasks according to established rules and logic, and providing a decision-making basis for valve control; The actuator module is responsible for receiving the control commands sent by the main controller module and converting them into actual mechanical actions. It drives the valve to adjust the angle position parameters of the target object. The precise control of the angle position parameters directly determines the degree of opening and closing of the valve, and then controls the key parameters such as the flow rate and pressure of the medium in the pipeline. The control signal is converted into actual physical operation to ensure that the valve can accurately execute the control command and guarantee the stable operation of the pipeline system. The detection sensor module uses sensing terminals distributed throughout the pipeline network to collect real-time dynamic data on site, covering key information such as temperature, flow, and pressure of the medium in the pipeline. By uploading this data to the main controller module, the system is provided with real-time operating status feedback, enabling the system to understand the operating status of the pipeline network in real time and provide accurate data support for the decision-making of the main controller module, thereby achieving intelligent and precise control of valve opening and closing; Through redundant backup channels, control can be quickly taken over when the main controller module or actuator unit fails, ensuring that the system maintains minimum basic functional operation, improving system reliability and stability, avoiding system paralysis due to key module failure, ensuring the continuous operation of the pipeline system in various unexpected situations, and reducing production losses and safety risks caused by failures.

[0022] The main controller module includes a data processing unit, a data analysis and output unit, and a control command sending unit; The data processing unit is used to remove interference from the external command signal and transmit the processed command signal to the data analysis and output unit; The data analysis output unit is used to perform logical operations on external command signals through code mapping to generate corresponding control strategies; The control command sending unit is used to send the generated control strategy to the downstream related components to coordinate the linkage work.

[0023] Specifically, the data processing unit applies filtering, noise reduction and other technical means to the external command signal to remove the mixed interference signals and restore the command signal to its original accurate state. The accuracy and reliability of the processed command signal are improved, and it can be smoothly transmitted to the data analysis and output unit, laying a solid foundation for subsequent logical operations and control strategy generation, ensuring that the entire system responds correctly based on accurate command signals. The data analysis output unit uses pre-set code mapping rules to perform deep logical operations on these command signals. By analyzing and comparing the command signals and matching them with the system's preset parameters, it generates corresponding control strategies to achieve precise control of the flow and pressure of the medium in the pipeline, providing an intelligent decision-making basis for the entire system and ensuring efficient and stable operation of the system. The control command sending unit is responsible for receiving the control strategies generated by the data analysis output unit, and converting these strategies into specific control commands, which are accurately sent to downstream actuator modules and other related components in a specific communication protocol and data format, so as to realize the effective control of the downstream components by the main controller module, so that each component can coordinate and work in accordance with the established control strategy, ensuring that the control strategy can be effectively implemented, guaranteeing the coordinated operation of the entire system, and enabling the system to complete various control tasks according to the expected goals.

[0024] The control strategies include: automatically adjusting the valve opening based on temperature changes to control the temperature of the medium in the pipeline and automatically adjusting the valve opening based on flow changes to control the flow of the medium in the pipeline.

[0025] Specifically, the two control strategies of automatically adjusting the valve opening based on temperature changes and automatically adjusting the valve opening based on flow changes can automatically adjust the valve opening by real-time monitoring of the temperature and flow data of the medium in the pipeline, accurately meeting the system's control requirements for medium temperature and flow, avoiding abnormal temperature or flow on system operation and equipment. It effectively maintains the stability of the medium environment and output in the pipeline, ensures the stability of the production process and system operation, and thus improves the operating efficiency and reliability of the entire system.

[0026] The actuator module includes a position execution unit and a fault monitoring and alarm unit; The position actuator is used to control the valve angle position parameter range by wrapping the stepper motor and its matching reduction gearbox assembly in a lightweight aluminum alloy shell to form the core driving source; The fault monitoring and alarm unit is used to detect the actual angular position of the actuator unit in real time, monitor abnormal instructions, and feed back abnormal instruction information to the main controller module and trigger an alarm reminder.

[0027] Specifically, a stable and reliable core drive source is built through the position execution unit. The stepper motor adopts the micro servo motor model XYZ-1234 series. It has a stable speed, low noise and low power consumption, making it the preferred power source for miniaturized and compact products. It can rotate accurately according to the received control signal, and the reduction gearbox assembly can adjust the speed of the stepper motor to meet the driving requirements of the valve under different working conditions, ensuring that the valve can be opened or closed to the specified angle accurately according to the control command issued by the main controller module, thereby effectively controlling the flow and pressure of the medium in the pipeline and ensuring the stable operation of the entire pipeline system. The fault monitoring and alarm unit detects the actual angular position of the actuator unit in real time, and compares the detection data with the instructions issued by the main controller module to ensure that the actuator's action is accurate. At the same time, it continuously monitors whether abnormal instructions are received, such as instruction format errors, instructions outside the normal range, etc., and feeds back abnormal instruction information to the main controller module, so that the main controller can take timely response instructions and trigger alarm reminders, effectively reducing the risks of system shutdowns, production accidents, etc. caused by actuator failures or abnormal instructions, and ensuring the stable and efficient operation of the entire automatic control valve switching system.

[0028] The valve's angle position parameter range is set at 0°-90°.

[0029] Specifically, by setting the valve angle to provide a clear and reasonable control range for valve switch control, the system can accurately adjust the valve opening, thereby flexibly controlling the flow, pressure and other parameters of the medium in the pipeline to meet the needs of different working conditions and ensure the stable operation of the pipeline system.

[0030] The detection sensing module includes a sensor monitoring unit and a data uploading unit; The sensor monitoring unit is used to collect real-time dynamic data on site through sensing terminals distributed at key nodes throughout the pipeline network; The data upload unit is used to accurately transmit the acquired on-site dynamic data to the main controller module as a reference for issuing command signals.

[0031] Specifically, the sensor monitoring unit uses various sensing terminals distributed at key nodes throughout the pipeline network to collect real-time dynamic data of the medium in the pipeline network, which can comprehensively and accurately reflect the operating status of the pipeline network. By collecting data in real time, it provides data for the operation analysis of the entire system, thereby gaining a clear and accurate understanding of the actual operation status of the pipeline medium, providing a reliable basis for subsequent control and decision-making, ensuring that the system can make reasonable adjustments in a timely manner according to actual conditions, and ensuring the stable and safe operation of the pipeline network; The on-site dynamic data obtained by the sensor monitoring unit is accurately processed and transmitted through the data upload unit to ensure that these data can be delivered to the main controller module completely and accurately, so that the real-time operation data of the pipeline network can be obtained in time, and accurate command signals can be issued based on this reference to achieve effective control and management of the pipeline network and improve the operating efficiency and reliability of the entire system.

[0032] The sensing terminal includes a temperature probe, a flow meter and a pressure sensor.

[0033] Specifically, the temperature probe can monitor the temperature of the medium in the pipeline in real time, providing the system with thermal status information, making it easier to adjust the valve opening according to temperature changes to maintain a suitable temperature. The flow meter can accurately measure the flow of the medium, allowing the system to grasp the flow data and thus reasonably control the valve to achieve precise flow regulation.

[0034] Redundant backup channels include: A backup independent battery pack to provide power to the system when the main power supply is lost; A backup controller, used to take over control when the main controller module fails; Backup actuator, used to take over valve control in the event of a failure of the actuator unit.

[0035] Specifically, the backup independent battery pack can quickly provide continuous power supply to the system in the event of an emergency when the main power supply is unexpectedly cut off. Due to unstable power supply conditions and poor grid quality in some areas, if a short interruption occurs, without a backup power supply, the system will face the risk of downtime, which will in turn affect the normal operation of the entire pipeline system. The backup independent battery pack can seamlessly take over the main power supply, ensuring the normal operation of each module in the system and enhancing the system's risk resistance. When the main control module fails, the backup controller will start up quickly and take over the execution of the preset control strategy to ensure uninterrupted system operation, maintain normal valve opening and closing, ensure pipeline stability, and reduce production risks and losses caused by failure of the main controller; After the backup actuator detects a fault, it responds quickly and takes over the work to ensure that the valve opens and closes as instructed, avoiding valve loss of control, ensuring pipeline safety, and reducing accidents and losses caused by abnormal valve control.

[0036] The system also includes a communication module, which is used to connect interconnected and shared information resources through standardized interface protocols to build a closed-loop ecological chain system.

[0037] Specifically, the communication module uses standardized interface protocols to achieve docking and information sharing among modules within the system and with external equipment systems, building a closed-loop ecological link, thereby improving system intelligence for accurate decision-making, enhancing reliability and stability to quickly adjust anomalies, and promoting scalability and compatibility, facilitating the integration of new modules, and reducing upgrade costs.

[0038] See attached Figure 6 , a method for automatically controlling valve opening and closing, the method comprising the following steps: S1. Receiving a start request: The main controller module receives a start command signal sent from the outside and generates a control strategy; S2, control command execution: send control commands to the actuators in the specified area through the actuator module to open, close or adjust the angle of the valve control strategy; S3. Real-time monitoring status: During the operation of the actuator, the status information of the valve and various parameters in the pipe network are obtained in real time through the detection sensor module; S4. Exception handling and feedback: Real-time monitoring of fault anomalies. In the event of an anomaly, the redundant backup channel is activated to take over control, maintain the system's minimum basic functions, and issue an alarm reminder.

[0039] Specifically, receiving a start request allows the main controller module to generate a control strategy based on external instructions, laying the foundation for subsequent operations. The valve can then be precisely controlled through the actuator module through the control command execution link to achieve operations such as opening, closing, or adjusting the angle. In this process, real-time monitoring of the status can use the detection sensor module to grasp the valve status and pipeline parameters in real time, providing a basis for system adjustment. Finally, through the exception handling and feedback mechanism, the redundant backup channel can be quickly started when a fault occurs, maintaining the basic functions of the system and issuing an alarm reminder. The overall automation and precision control of the valve switch is realized, which improves the stability and reliability of the system operation, reduces the impact of faults, and ensures the safe and efficient operation of the pipeline system.
