Description

Technical Field

[0001] This invention relates to the field of solenoid valve technology, and in particular to a control system for opening and closing a solenoid valve based on Beidou navigation. Background Technology

[0002] Remote and precise control of solenoid valves is crucial in numerous fields, including industrial production, water conservancy projects, and data acquisition and monitoring. Traditional solenoid valve control methods largely rely on terrestrial network communication, such as 4G and 5G. However, in remote areas, mountainous regions, and oceans where network coverage is weak or absent, these terrestrial network-based control methods often fail to function properly, severely limiting the remote operation of solenoid valves. This leads to reduced production efficiency, increased maintenance costs, and may even pose safety hazards.

[0003] Although some solutions currently use satellite communication technology to achieve remote valve control, they generally suffer from problems such as poor communication stability, low data transmission rate, insufficient control accuracy, and excessive system complexity. Therefore, there is an urgent need for a control system based on the BeiDou system to achieve stable, efficient, and precise control of the opening and closing of solenoid valves. Summary of the Invention

[0004] The purpose of this invention is to solve the above-mentioned problems by providing a control system based on Beidou-driven solenoid valve opening and closing that enables remote and precise control of solenoid valves in remote areas, mountainous regions, and other areas, without being limited by ground network coverage. This greatly expands the application range of solenoid valves, and the opening and closing of solenoid valves takes into account various environmental conditions, making sampling more accurate.

[0005] To achieve the above objectives, the technical solution of the present invention is: a control system for opening and closing a solenoid valve based on BeiDou navigation, comprising a BeiDou satellite communication module, a central control unit, a drive module, and a solenoid valve body. The BeiDou satellite communication module is used to receive signals from multiple BeiDou satellites to improve the accuracy and stability of signal reception. The central control unit is used to receive BeiDou signals and preset control signals; The drive module generates opening and closing actions based on the control signals sent by the central control unit; The solenoid valve body enables precise control of the fluid.

[0006] Preferably, the BeiDou satellite communication module can detect the opening and closing time period, latitude and longitude, and altitude of the solenoid valve body, where altitude includes absolute altitude and relative altitude.

[0007] Preferably, the drive module can control the opening, closing, opening degree, and running time of the solenoid valve body.

[0010] Preferably, the microprocessor in the central control unit is equipped with a signal conditioning circuit, a power management circuit, and a communication interface circuit. The signal conditioning circuit filters, amplifies, and performs analog-to-digital conversion on the signal fed back from the solenoid valve. The power management circuit provides a stable power supply to the field control unit. The communication interface circuit enables the field control unit to communicate with other devices.

[0016] The present invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the invention in a schematic manner, and therefore only show the components relevant to the invention.

[0017] Please refer to Figure 1-4 A control system for opening and closing a solenoid valve based on BeiDou navigation includes a BeiDou satellite communication module, a central control unit, a drive module, and a solenoid valve body. The drive module can be integrated into the solenoid valve. The BeiDou satellite communication module is used to receive signals from multiple BeiDou satellites to improve the accuracy and stability of signal reception. The central control unit is used to receive BeiDou signals and preset control signals. The drive module generates opening and closing actions according to the control signals sent by the central control unit. The solenoid valve body realizes precise control of the fluid.

[0018] First, install the BeiDou satellite communication module in a location where it can effectively receive BeiDou satellite signals, ensuring the antenna is correctly oriented and there are no obvious obstructions. Then, connect and install the central control unit, solenoid valve drive module, and solenoid valve body according to the system design requirements. After installation, debug the system. Receive satellite signals through the BeiDou signal receiving module and check if the signal strength and quality meet the requirements. Use debugging tools to set parameters and perform functional tests on the central control unit, ensuring it can correctly parse BeiDou signals and generate corresponding control signals. Test the driving capability of the solenoid valve drive module to check if it can normally drive the solenoid valve. Finally, test the control performance of the entire system by sending control commands to ensure the solenoid valve can accurately respond to control commands and achieve opening and closing actions.

[0019] In this embodiment, the Beidou satellite communication module can detect the opening and closing time period, latitude and longitude, and altitude of the solenoid valve body, where altitude includes absolute altitude and relative altitude.

[0020] The solenoid valve body and control system are installed on a drone, which flies to a predetermined location to collect and sample fluids or gases. In other words, sampling is not limited to gas and water samples, but can also be performed on other fluids.

[0021] The time period includes the UAV takeoff time, estimated flight time, estimated sampling time, and redundancy; latitude and longitude include the latitude and longitude of the sampling point; absolute altitude is the absolute altitude of the takeoff point + the height of the highest building or ground surface along the route + 50m redundancy; relative altitude is the absolute altitude value that the UAV descends to after reaching the latitude and longitude of the sampling point; the solenoid valve can be remotely and precisely opened and closed through the Beidou satellite communication module. When the solenoid valve meets the four conditions of time period, latitude and longitude, and altitude (absolute altitude and relative altitude), the solenoid valve is activated for the collection and sampling of fluid or gas; when one of the four conditions is not met, the solenoid valve is closed.

[0022] Understandably, the solenoid valve is installed on the pipeline and operates in conjunction with the pump; it can also be installed on a drone, which flies to a designated area to collect samples. Of course, sampling can also be done manually by hand or by other means.

[0023] Solenoid valves utilize BeiDou satellite communication, enabling the entire system to operate without being limited by terrestrial network coverage. This allows for remote and precise control of solenoid valves in remote areas, mountainous regions, and other areas where network signals are difficult to reach. This significantly expands the application range of solenoid valves and provides reliable control solutions for industrial production, water conservancy projects, and flow / gas collection in these regions.

[0024] In this embodiment, the drive module can control the opening, closing, opening degree, and running time of the solenoid valve body, and can conveniently send various control commands, such as opening the valve, closing the valve, and adjusting the valve opening degree.

[0025] The solenoid valve integrates position, pressure, and flow sensors, which collect real-time operating status information and feed it back to the central control unit. The solenoid valve is also equipped with a high-precision drive motor and control circuitry, enabling precise control of the valve's opening, closing, and opening degree adjustment based on control signals sent from the field control unit, thus achieving precise fluid control.

[0026] The central control unit includes a data processing module and a data storage module. The solenoid valve body sends its operating data to the data storage module in the central control unit, where the data is stored. This module has a built-in control algorithm and intelligent decision-making system, which can precisely control the opening and closing state of the solenoid valve based on the received BeiDou signal and preset control rules. The microprocessor in the central control unit is equipped with a signal conditioning circuit, a power management circuit, and a communication interface circuit. The signal conditioning circuit filters, amplifies, and performs analog-to-digital conversion on the signal fed back from the solenoid valve. The power management circuit provides a stable power supply to the field control unit, and the communication interface circuit enables communication between the field control unit and other devices.

[0027] Based on the above embodiments, this system utilizes the short message communication function of the BeiDou satellite to transmit remote control commands and send back equipment status information. Users can send control commands to the BeiDou Short Message Service Center via the Internet through mobile apps, computer clients, and other terminal devices. The BeiDou Short Message Service Center then forwards the commands via satellite to the BeiDou signal receiving module in the system. After receiving the commands, the system executes the corresponding control operations and sends the current status information of the solenoid valve (such as open / closed status, fault information, etc.) back to the BeiDou Short Message Service Center in the form of short messages through the BeiDou signal receiving module. The service center then forwards the information to the user terminal, thereby realizing two-way communication between the user and the system.

[0028] Working principle: When operators at the monitoring center send solenoid valve control commands via mobile phone or computer, the commands are first packaged and encrypted by the monitoring center's server, and then sent to the BeiDou satellite communication module via the network. The BeiDou satellite communication module modulates the encrypted commands onto satellite signals and transmits them over the area where the field control unit is located via satellite link. After receiving the satellite signals, the BeiDou satellite communication module of the field control unit demodulates, decrypts, and verifies them, extracts the original control commands, and sends them to the drive module. The drive module parses the received control commands, determining the command type and the target solenoid valve. If the command is to open or close the valve, the drive module generates a corresponding drive signal, which controls the solenoid valve's drive motor via the drive circuit to open or close the valve. If the command is to adjust the valve opening, the drive module generates a precise control signal based on the opening value in the command and the current opening state of the solenoid valve. This signal is then used to precisely adjust the valve opening via the drive motor, bringing the valve to the specified opening position. During the operation of the solenoid valve, its built-in sensors collect real-time operating status information, such as valve position, pressure, and flow rate. This information is processed by the signal conditioning circuit and then sent to the microcontroller. The microcontroller packages and encrypts this status information and then transmits it back to the data storage module via the BeiDou satellite communication module. Upon receiving the status information, the data storage module demodulates, decrypts, and verifies it, then sends the processed information to the server. The server stores this information in a database and displays the solenoid valve's operating status in real-time on the human-machine interface through monitoring software, allowing operators to monitor the equipment's operation at any time.

[0029] Based on the above embodiments, after sampling, the solenoid valve is closed, and the designated laboratory is located by latitude, longitude, and altitude values, and is only opened during a designated time period; After sampling, the solenoid valve is kept closed throughout the transportation process, which ensures the airtightness of the sample, prevents external oxidizing substances from oxidizing and interfering with the sample, and also ensures the authenticity of the sample.

[0030] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
