Description

Technical Field

[0001] This application relates to the field of electronic technology, and to, but is not limited to, power valve control devices, management boards, and methods for starting power valve control devices. Background Technology

[0002] Currently, the verification of power valve control devices typically involves identifying the version numbers of different circuit boards and then determining whether the actual version number matches the expected version number. If they match, the power valve control device is activated. However, in practice, even when the actual version number matches the expected version number, problems can still occur in the operation of the power valve control device. Summary of the Invention

[0003] This application provides a power valve control device, a management board, and a method for starting the power valve control device, wherein:

[0004] In a first aspect, embodiments of this application provide a power valve control device, comprising: a management board, a first board, and a backplane; the first board includes one or more of the following: an application board, a power board, an I / O general board, an input board, an output board, an interface board, and a data acquisition board; wherein the management board and the first board are respectively inserted into different slots on the backplane; the first board is used to identify the actual first slot number inserted, and to perform a first verification by comparing the first slot number with a second slot number into which the first board is inserted; if the first verification passes, the first slot number and the first board type of the first board are sent to the management board; the management board is used to perform a second verification on the first board; the second verification includes: verifying the first board type with the board type into which the first slot number is inserted, and verifying the first slot number with a third slot number into which the first board type is inserted; the management board is used to activate each board of the power valve control device to operate the power valve control device if the second verification of each first board passes.

[0005] It is understood that, in this embodiment, if the first board verifies and passes the verification between the actual inserted first slot number and the specified second slot number that allows the board to be inserted, the management board verifies the first board type against the specified type of board inserted into the first slot number, and verifies the first slot number against the specified third slot number. If the verification of each first board passes, the management board activates each board of the power valve control device to run the power valve control device. In other words, the first board performs a self-test first, and then the management board performs a secondary verification of the first board. This helps ensure that the software-defined first board matches the actually inserted first board, thereby comprehensively improving the safety and availability of the power valve control device when the configuration of the power valve control device conforms to the predefined functions.

[0006] In some embodiments, the management board is configured to: identify the actual inserted fourth slot number, and perform a third verification by comparing the fourth slot number with the fifth slot number into which the management board is to be inserted; and perform a second verification on the first board if the third verification passes.

[0007] It is understood that, in this embodiment, if the management board verifies and passes the verification between its actual fourth slot number and the designated fifth slot number, the board type of the slot number into which the first board is actually inserted is verified. This helps ensure compatibility between the management board and its corresponding software code, thereby ensuring the normal operation of the power valve control device.

[0008] In some embodiments, the second verification passes if: the first board type is consistent with the board type inserted into the specified first slot number, and the first slot number is consistent with the third slot number inserted into the specified first board type.

[0009] It is understood that in the embodiments of this application, the first board type is consistent with the board type inserted in the specified first slot number, and the first slot number is consistent with the third slot number inserted in the specified first board type, indicating that the actually inserted first board is a software-defined first board. This is beneficial to ensure that the software-defined first board matches the actually inserted first board, thereby comprehensively improving the safety and availability of the power valve control device when the configuration of the power valve control device meets the predefined functions.

[0010] In some embodiments, the management board is further configured to: control the alarm light of the first board that failed the second verification to output a first alarm signal, and control the alarm light of the management board to output a second alarm signal, in the event that the second verification of any first board fails; wherein, the second verification failure includes: the type of the first board is inconsistent with the type of board inserted into the specified first slot, and / or, the first slot number is inconsistent with the third slot number of the specified first board type.

[0011] It is understood that in this embodiment, if the first board type is inconsistent with the type of board inserted into the specified first slot, and / or the first slot number is inconsistent with the third slot number into which the first board type is inserted, it indicates that the software-defined first board does not match the actually inserted first board. Therefore, the management board controls the alarm light of the first board that failed the second verification to output a first alarm signal, and controls the alarm light of the management board to output a second alarm signal. Thus, the first alarm signal from the first board's alarm light and the second alarm signal from the management board's alarm light indicate a mismatch between the software-defined first board and the actually inserted first board, thereby helping users to promptly detect and resolve the problem of "the software-defined first board not matching the actually inserted first board."

[0012] In some embodiments, the second verification fails when: the first board type is inconsistent with the board type inserted into the specified first slot number, or the first slot number is inconsistent with the third slot number inserted into the specified first board type; the first alarm signal includes alarm light flashing and / or the alarm light color is a first color, and the second alarm signal includes alarm light flashing and / or the alarm light color is a second color.

[0013] It is understood that in this embodiment, if the first board type is inconsistent with the type of board inserted into the specified first slot, or if the first slot number is inconsistent with the third slot number into which the first board type is inserted, then the first alarm signal includes alarm light flashing and / or the alarm light color being a first color, and the second alarm signal includes alarm light flashing and / or the alarm light color being a second color. Thus, by using the alarm light flashing and / or the alarm light color of the first board and the alarm light flashing and / or the alarm light color of the management board to indicate a mismatch between the software-defined first board type and the actual inserted first board type or the inserted slot number, it is beneficial for users to promptly detect and resolve the problem of "the first board type being inconsistent with the type of board inserted into the specified first slot number or the first board type or the inserted slot number not matching the actual inserted first board type."

[0014] In some embodiments, the second verification fails when: the first board type is inconsistent with the board type inserted into the specified first slot number, and the first slot number is inconsistent with the third slot number inserted into the specified first board type; the first alarm signal includes the alarm light being lit and / or the alarm light color being a third color, and the second alarm signal includes the alarm light being lit and / or the alarm light color being a fourth color.

[0015] It is understood that in this embodiment, the first board type is inconsistent with the type of board inserted into the specified first slot, and the first slot number is inconsistent with the third slot number into which the first board type is inserted. Therefore, the first alarm signal includes the alarm light being lit and / or the alarm light color being a third color, and the second alarm signal includes the alarm light being lit and / or the alarm light color being a fourth color. Thus, by using the alarm light lighting and / or the alarm light color of the first board and the alarm light lighting and / or the alarm light color of the management board to indicate a mismatch between the software-defined first board type and the actually inserted board type, and between the first slot number and the actually inserted second slot number, it is beneficial for users to promptly detect and resolve the problem of "the software-defined first board type being inconsistent with the type of board inserted into the specified first slot and the software-defined first slot number being inconsistent with the third slot number into which the first board type is inserted."

[0016] In some embodiments, the management board is used to: control the alarm light of the management board to output a third alarm signal if the third verification fails; wherein, the failure of the third verification includes: the fourth slot number is inconsistent with the fifth slot number into which the management board is inserted.

[0017] It is understood that in this embodiment, if the actual fourth slot number inserted into the management board is inconsistent with the specified fifth slot number, the management board's alarm light will output a third alarm signal. This allows users to promptly detect and resolve the issue of "incorrect slot number inserted into the management board" through the third alarm signal from the management board's alarm light, rather than misjudging it as a failure of the first board's second verification when both the management board and the first board fail their self-tests.

[0018] In some embodiments, the first board is configured to control the alarm light of the first board to output a fourth alarm signal if the first verification fails; wherein, the first verification failure includes: the first slot number is inconsistent with the second slot number into which the first board is to be inserted.

[0019] It is understood that in this embodiment, if the actual first slot number into which the first board is inserted is inconsistent with the specified second slot number into which the first board is inserted, the alarm light on the first board will output a fourth alarm signal. This allows users to promptly detect and resolve the issue of "incorrect slot number of the first board" through the alarm light on the first board, rather than misjudging it as a failure of the second verification of the first board when both the management board and the first board's self-tests fail.

[0020] Secondly, embodiments of this application provide a management board, which is used to: receive a first slot number and a first board type from a first board; wherein the first slot number is the actual slot number in which the first board is inserted into the slot of the backplane of the power valve control device; the first slot number and the first board type are sent to the management board by the first board after a first verification is performed between the first slot number and a specified second slot number into which the first board is inserted, and the verification passes; wherein the first board includes one or more of the following: application board, power board, I / O general board, input board, output board, interface board, acquisition board; perform a second verification on the first board; the second verification includes: verifying the first board type with the board type into which the specified first slot number is inserted, and verifying the first slot number with a third slot number into which the specified first board type is inserted; and, if the second verification of each first board passes, start each board of the power valve control device to run the power valve control device.

[0021] Thirdly, embodiments of this application provide a method for starting a power valve control device. This method is applied to a management board and includes: receiving a first slot number and a first board type from a first board; the first slot number and first board type are sent to the management board by the first board after a first verification is performed between the first slot number and a predetermined second slot number into which the first board is inserted, and the verification passes; wherein the first slot number is the actual slot number of the first board inserted into the slot on the backplane of the power valve control device; wherein the first board includes one or more of the following: an application board, a power board, an I / O general board, an input board, an output board, an interface board, and a data acquisition board; performing a second verification on the first board; the second verification includes: verifying the first board type against the board type into which the predetermined first slot number is inserted, and verifying the first slot number against a third slot number into which the predetermined first board type is inserted; and, if the second verification of each first board passes, starting each board of the power valve control device to operate the power valve control device.

[0038] (1) Energy storage valve control device

[0039] Energy storage valve control devices are key components in power energy storage systems used to monitor and control energy storage devices to ensure their safe and efficient operation. By precisely controlling the opening and closing of energy storage valves, these devices regulate the inflow and outflow of the energy storage medium, thereby meeting the energy demands of the power grid or load.

[0040] The working principle of the energy storage valve control device is based on the closed-loop control principle. It acquires real-time status information of the energy storage device, compares it with a preset control target, and calculates the control deviation. Then, based on the magnitude and direction of the deviation, it issues corresponding control commands to the submodules to adjust the opening and closing degree of the energy storage valve, thereby achieving precise control of the energy storage process.

[0041] Energy storage valve control devices in power energy storage systems are widely used in various energy storage scenarios, including but not limited to:

[0042] Battery energy storage systems: such as lithium-ion batteries, sodium-sulfur batteries and other electrochemical energy storage systems. Energy storage valve control devices are used to control the charging and discharging process of the battery to ensure the safe and stable operation of the battery.

[0043] Pumped storage system: In a pumped storage power station, the energy storage valve control device is used to control the flow of water in and out, realizing the mutual conversion of electrical energy and potential energy.

[0044] Compressed air energy storage system: In a compressed air energy storage system, the energy storage valve control device is used to control the compression and release process of air to realize the storage and release of electrical energy.

[0045] (2) Extension device

[0046] In current energy storage systems, it is common to connect submodules to energy storage valve control devices via expansion devices. These expansion devices can be understood as middleware or interface equipment, acting as a bridge between the submodules and the energy storage valve control devices.

[0047] The expansion unit provides interfaces compatible with submodules and energy storage valve control devices, enabling seamless transmission of uplink submodule information and downlink control commands. This resolves the issue of interface incompatibility between different devices, allowing submodules to be successfully integrated into the energy storage system. Data transmission between the expansion unit and the submodules and energy storage valve control devices occurs via specific interface communication protocols. These protocols need to be predefined to ensure that all parties can correctly understand and process the received data.

[0048] In addition to basic interface adaptation functions, expansion devices may also have additional functions such as signal amplification, filtering, and isolation to improve the stability and reliability of data transmission. These functions help improve the overall performance of the energy storage system.

[0049] In energy storage systems, expansion units can also serve as redundant backups. When a valve control device or a submodule fails, the expansion unit can take over its operation, ensuring the continuous operation of the energy storage system. This design improves the system's reliability and stability.

[0050] (3) Management board

[0051] The management board of the power valve control device is one of the key components to ensure the stable operation of the power system. Through multiple functions such as control, monitoring, self-testing, alarm, data processing, and communication, it provides strong support for the safe and reliable operation of the power system.

[0052] The management board is the core control unit in a power valve control device. It is responsible for receiving instructions from the upper-level system or controller and, based on these instructions, precisely controlling the power valves (such as converter valves and circuit breaker valves). This includes valve opening, closing, and adjustment actions to ensure the stable operation of the power system.

[0053] Meanwhile, the management board also possesses powerful monitoring capabilities, enabling it to monitor the operating status, current, voltage, and other key parameters of the power valve in real time. Upon detecting any abnormalities, such as overload or short circuit, the management board will respond immediately and take appropriate protective measures to prevent the accident from escalating.

[0054] To improve system reliability and security, management boards typically possess comprehensive self-testing capabilities. During system startup or operation, the management board automatically checks its own hardware and software to ensure all functions are working properly. If a fault or anomaly is detected, the management board immediately sends an alarm signal to alert the operator.

[0055] When a system malfunctions, the management board requests a system switchover to prevent the fault from escalating or causing more serious consequences. For example, if a backup system is available, the management board will activate the backup system to ensure continuous power supply to the power system.

[0056] The management board is also responsible for processing data from sensors, actuators, and other devices. By analyzing and processing this data, the management board can more accurately determine the operating status of the electric valve, providing a basis for subsequent control decisions.

[0057] In addition, the management board has powerful communication capabilities. It can exchange data and transmit commands with other control units and monitoring systems, enabling remote monitoring and centralized management of the power system.

[0058] Depending on the specific application requirements, management boards may also have additional functions, such as storage, configuration, or digital signal processing. These functions make management boards more flexible and powerful, enabling them to better adapt to various complex power system environments.

[0059] (4) Application board

[0060] In power valve control devices, the presence and specific function of the application board vary depending on different system designs and requirements. Generally, however, the application board performs the following functions:

[0061] The application board serves as an auxiliary control unit for the management board, responsible for performing relatively simple or auxiliary control tasks. This reduces the burden on the management board and improves the overall system's control efficiency and response speed.

[0062] In high-load or complex control scenarios, the application board can share some of the load with the management board, enabling parallel processing or distributed control. This helps improve the system's processing power and stability.

[0063] The application board can also be responsible for implementing certain control functions or algorithms, such as precisely controlling the valve opening degree and implementing specific protection strategies.

[0064] In some power systems with extremely high reliability requirements, application boards may also serve as redundant backup units for management boards. If a management board fails or malfunctions, the application board can immediately take over control tasks, ensuring the continuous and stable operation of the power system.

[0065] (5) Power supply board

[0066] The power board of the power valve control device not only provides a stable and reliable power supply for the power valve control device in the power system, but also has many advantages in terms of power management, stability and reliability, as well as adaptability and compatibility.

[0067] The power supply board is the main power supply unit of the electric valve control device. It is responsible for converting external power (such as AC power, DC power, etc.) into the voltage and current required by the device to ensure that the electric valve control device can work normally.

[0068] In some power valve control devices, the power board is also equipped with a backup power supply (such as a battery pack). Once the main power supply fails or is interrupted, the backup power supply can immediately take over to ensure the continuous power supply to the power valve control device, thereby avoiding serious consequences such as system paralysis or data loss.

[0069] The power board has the ability to regulate voltage and current. It can automatically or manually adjust the output voltage and current according to the actual needs and working status of the power valve control device to ensure that the equipment operates in the best working condition.

[0070] The power board also features power protection and isolation functions, preventing damage to the power valve control device from external power fluctuations, interference, or faults. For example, when abnormal conditions such as overvoltage, undervoltage, or overcurrent occur in the external power supply, the power board can quickly cut off the power or activate the protection mechanism to protect the equipment.

[0071] The power board significantly improves the stability of the electric valve control device and the electric valves it controls by providing a stable and reliable power supply. A stable power supply helps reduce equipment failures and downtime, and improves the overall operating efficiency of the system.

[0072] Power boards are typically made with high-quality materials and advanced manufacturing processes, resulting in high reliability and durability. Furthermore, some power boards also feature self-diagnostic and self-recovery functions, enabling them to automatically detect and repair problems when faults occur, thereby further enhancing system reliability.

[0073] The power board can adapt to different working environments and conditions, including temperature, humidity, and electromagnetic interference. Through the use of special design and materials, the power board can maintain stable performance in harsh working environments.

[0074] Power supply boards typically possess broad compatibility, enabling them to adapt to different types of power valve control devices and power valves. This compatibility allows power supply boards to have a wider range of applications and greater value in power systems.

[0075] (6) I / O universal board

[0076] The I / O general-purpose board of the power valve control device has multiple functions in the power system, including signal input and output, signal processing and conversion, flexibility and scalability, real-time monitoring and diagnosis, and remote control and communication.

[0077] The I / O general-purpose board is responsible for acquiring various input signals from external devices. These signals may include digital signals (such as the status of buttons and switches) and analog signals (such as the measured values ​​of sensors for temperature, pressure, and liquid level). These signals represent the status and information of the control site and are important bases for the decision-making and control of power valve control devices.

[0078] In addition to signal input, the I / O general-purpose board is also responsible for sending control commands to external devices in the form of output signals. These output signals can drive actuators, motors, valves, and other actuators to achieve precise control of electric valves. The output signals also include two types: digital signals and analog signals, which are used to control the on / off state and operating parameters of the equipment, respectively.

[0079] During the acquisition of input signals, general-purpose I / O boards typically perform filtering, level conversion, and isolation to improve signal stability and reliability. These processes help reduce the impact of external interference and noise on the system, ensuring accurate signal transmission.

[0080] The I / O general-purpose board also features signal conversion capabilities, converting input signals from external devices into digital signals for further processing and control by the power valve control device. Digital signals offer higher accuracy than analog signals, reducing errors caused by the physical characteristics of sensors and actuators.

[0081] I / O general purpose boards typically employ a modular design, allowing users to add or remove specific input / output channels as needed to adapt to different application scenarios. This flexibility enables power valve control devices to meet the ever-changing demands of industrial production and maintain a high degree of adaptability.

[0082] As a standard product, the I / O universal board offers high compatibility and interchangeability across different manufacturers and models. This helps reduce the risk of equipment configuration and wiring errors, increases manufacturing speed and acceptance testing efficiency, and lowers overall costs.

[0083] The I / O universal board can monitor the operating status of electric valves and the status of input and output signals in real time, providing real-time performance feedback to the system. By monitoring the system's input and output status, engineers can promptly identify potential problems and perform corresponding maintenance and repairs.

[0084] Some general-purpose I / O boards also have fault diagnosis capabilities, which can automatically detect and diagnose faults in the input and output channels. This helps to quickly locate the source of the fault, improve the efficiency of fault handling, and reduce downtime in production.

[0085] With the development of information and remote technologies, general-purpose I / O boards can also support remote control functions. Through communication connections with other control units or monitoring systems, power valve control devices can achieve remote monitoring and control, improving the overall operating efficiency and reliability of the system.

[0086] I / O general-purpose boards typically have standard communication interfaces and protocols, enabling data exchange and command transmission with other devices. This communication capability allows power valve control devices to be integrated into the overall monitoring and management system of the power system, realizing comprehensive information utilization and expanding automated control.

[0087] (7) Input plate

[0088] The input board of the power valve control device has multiple functions in the power system, including signal reception and acquisition, protection and control, remote monitoring and communication, and reliability and stability.

[0089] The input board is responsible for receiving input signals from external devices or systems. These signals may be digital signals (such as the on / off state of buttons or switches) or analog signals (such as continuously changing physical quantities such as temperature and pressure measured by sensors).

[0090] The input board acquires and processes the received signals, converting them into a form that the power valve control device can recognize and process. This may include signal filtering, amplification, and conversion processes to ensure signal accuracy and reliability.

[0091] Input circuit boards serve as protection circuits in power systems. By monitoring the status of input signals in real time, they can promptly disconnect or isolate relevant circuits when abnormal conditions (such as overload, short circuit, equipment failure, etc.) are detected, thus preventing equipment damage and accidents.

[0092] The input board also participates in the implementation of control logic. Based on the received signals and preset control strategies, the input board can trigger corresponding control actions, such as opening or closing power valves and adjusting valve openings, to achieve precise control of the power system.

[0093] The input board is typically connected to other parts of the power valve control device (such as the main control board, communication module, etc.), providing an interface for remote monitoring. Through the remote monitoring system, operators can view the operating status of the power valve control device, the status of input signals, and other information in real time, thereby achieving remote monitoring and management of the power system.

[0094] The input board also has communication capabilities, enabling data exchange and command transmission with other devices or systems. Through standard communication protocols and interfaces, the input board can achieve interconnection with higher-level dispatch centers, other control systems, etc., realizing comprehensive information sharing and automated control.

[0095] Input boards typically employ high-quality components and manufacturing processes to ensure stable and reliable operation in harsh electrical environments. This contributes to improving the overall reliability and stability of power valve control devices.

[0096] The input board also has a certain anti-interference capability, which can resist electromagnetic interference and noise from inside and outside the power system, ensuring accurate signal transmission and reliable signal processing.

[0097] (8) Opening the board

[0098] The output board of the power valve control device has multiple functions in the power system, including control signal output, drive actuator, real-time response and protection, and remote monitoring and communication.

[0099] The output board is responsible for receiving instructions from the main control board or other control units and converting these instructions into corresponding control signals for output. These control signals directly act on electric valves or other actuators to achieve precise control of the power system equipment.

[0100] The board supports various types of control signal outputs, including digital signals (such as high and low level signals, pulse signals, etc.) and analog signals (such as voltage and current signals, etc.) to meet the control signal requirements of different devices.

[0101] In electric valve control devices, the control panel typically controls the electric valve by driving a relay. When a control command is received, the control panel sends a drive signal to the relay, causing the relay to activate and thus controlling the opening or closing of the electric valve.

[0102] In some complex electric valve control devices, the control board may need to drive multiple relays simultaneously to achieve coordinated control of multiple electric valves. In this case, the control board needs to have efficient multi-relay management capabilities to ensure that each relay operates in a predetermined sequence and timing.

[0103] Electrically operated valve control devices require a high response speed to control signals, especially in emergency situations. The control panel needs to have a rapid response capability, able to output the corresponding control signal immediately upon receiving a control command to ensure that the electric valve can operate in a timely manner.

[0104] To ensure the safe and reliable operation of power valve control devices, the output board typically incorporates multiple protection mechanisms. For example, when outputting control signals, the output board performs signal verification and error detection to ensure signal accuracy and reliability. Simultaneously, upon detecting abnormal conditions (such as relay failure or signal anomalies), the output board immediately cuts off the output signal and issues an alarm signal to prevent equipment damage and accidents.

[0105] Modern power valve control devices typically have remote monitoring capabilities. As a key component for control signal output, the switchboard also needs to provide a remote monitoring interface. Through a remote monitoring system, operators can view the switchboard's operating status, control signal output, and other information in real time, thereby achieving remote monitoring and management of the power valve control device.

[0106] To enable remote monitoring and management, the control board also needs communication capabilities. It can exchange data and transmit commands with other devices or systems through standard communication protocols and interfaces. This facilitates the intelligent, networked, and integrated management of power valve control devices.

[0107] (9) Interface board

[0108] The interface board of the power valve control device has multiple functions in the power system, including signal transmission and conversion, electrical isolation and protection, flexibility and scalability, as well as remote monitoring and communication.

[0109] An interface board serves as a bridge for signal transmission between an electric valve control device and external equipment or systems. It is responsible for transmitting control signals from the controller to the electric valve or other actuators, while also feeding back status signals from the electric valve to the controller.

[0110] Since different devices or systems may use different signal types and communication protocols, the interface board also has signal conversion capabilities. It can convert control signals from the controller into signal types that the electric valve can recognize, and at the same time, it can convert the status signals of the electric valve into signal types that the controller can process.

[0111] The interface board provides electrical isolation during signal transmission, preventing electrical interference and noise from affecting control signals. This helps improve system stability and reliability.

[0112] The interface board also has multiple protection mechanisms, such as overcurrent protection and overvoltage protection, to prevent damage to the power valve control device caused by external equipment failure or improper operation.

[0113] Interface boards typically employ a modular design, allowing users to select and configure them according to their specific needs. This design approach enhances the system's flexibility and scalability, enabling power valve control devices to adapt to different application scenarios and changing requirements.

[0114] The interface board supports various types of interfaces and communication protocols, such as Electronic Industries Alliance Recommended Standard 232 (EIA RS-232), Electronic Industries Alliance Recommended Standard 485 (EIA RS-485), and Controller Area Network (CAN) bus, enabling the power valve control device to connect and communicate with various external devices or systems.

[0115] The interface board provides a remote monitoring interface, allowing operators to view the operating status and parameter information of the power valve control device in real time through a remote monitoring system. This facilitates remote monitoring and management of the power system.

[0116] The interface board has communication capabilities, enabling data exchange and command transmission with other devices or systems. Through standard communication protocols and interfaces, the power valve control device can be integrated into the overall monitoring and management system of the power system, achieving comprehensive information sharing and expanding automated control.

[0117] (10) Data Acquisition Board

[0118] The acquisition board of the power valve control device has multiple functions in the power system, including signal acquisition and processing, real-time monitoring and status feedback, data storage and recording, strong anti-interference ability, and flexible configuration and expansion.

[0119] The data acquisition board is responsible for acquiring various analog and digital signals from the power system in real time, such as measured values ​​of physical quantities like current, voltage, temperature, and pressure. These signals are crucial for the decision-making and control of power valve control devices.

[0120] The acquisition board performs necessary processing on the acquired signals, including filtering, amplification, and conversion, to improve the signal-to-noise ratio and accuracy. The processed signals are then more suitable for subsequent control and monitoring.

[0121] The data acquisition board can monitor the operating status of the power system in real time, including the on / off status of power valves and changes in current and voltage. This real-time monitoring helps to promptly detect anomalies and faults in the system, allowing for appropriate measures to be taken to address them.

[0122] The acquisition board feeds back the processed signals and power system status information to the controller or other relevant equipment. This feedback information provides crucial information for the controller's decision-making, contributing to the automated control and optimized operation of the power system.

[0123] Acquisition boards typically have data storage capabilities, allowing them to store acquired data in internal or external storage devices. This data can then be used for subsequent analysis, processing, and report generation.

[0124] By storing historical data, the acquisition board can record the operating history of the power system, including the changing trends of various parameters and the occurrence of abnormal events. These historical records are of great significance for fault diagnosis, performance evaluation, and optimal design of the power system.

[0125] To improve the anti-interference capability of the acquisition board, electromagnetic compatibility design is usually adopted, such as using ferrite beads, capacitors and other devices to effectively isolate digital circuits, analog circuits and power modules, and reduce mutual interference.

[0126] The acquisition board uses high-quality components and manufacturing processes to ensure stable and reliable operation in harsh power environments.

[0127] Data acquisition boards typically employ a modular design, allowing users to select and configure them according to their specific needs. This design approach enhances the system's flexibility and scalability, enabling power valve control devices to adapt to different application scenarios and changing requirements.

[0128] Acquisition boards typically have multiple acquisition channels, which can simultaneously acquire signals of multiple parameters, improving the efficiency and accuracy of data acquisition.

[0129] (11) Back panel

[0130] The backplate of the power valve control device plays an important role in fixing and supporting, electrical connection and communication, optimized layout and heat dissipation, as well as protection and anti-interference.

[0131] As a fundamental component of power valve control devices, the backplane is primarily used to secure various electrical components and wiring connections. These components include circuit boards, interface boards, and data acquisition boards, which are firmly mounted on the backplane using fixing devices (such as screw holes and slots).

[0132] The backplate provides a robust support structure for the entire electric valve control device, ensuring that the device remains stable during operation and will not malfunction due to loose components or vibration.

[0133] The backplane typically contains power buses and signal buses, which provide electrical connections and communication channels for the various components within the power valve control device. The power bus is responsible for providing the necessary electrical energy to the components, while the signal bus is used to transmit control signals and data information.

[0134] In some high-reliability power valve control devices, the backplane may also employ a redundant design, containing multiple completely independent and mutually redundant power and signal buses. This design improves system reliability and fault tolerance, ensuring the system can still operate normally even if one bus fails.

[0135] The backplane, by providing fixed points and bus design, helps optimize the layout of components within the power valve control device. A well-planned layout reduces interference and conflicts between components, improving the overall performance and stability of the system.

[0136] Some backplane materials (such as aluminum alloys) also have good heat dissipation properties. During the operation of power valve control devices, components generate a certain amount of heat. The heat dissipation function of the backplane can effectively dissipate this heat, preventing components from being damaged due to overheating.

[0137] The backplate also provides some protection for the components inside the power valve control device. For example, it can prevent external dust, moisture, and other impurities from entering the power valve control device and damaging the components.

[0138] Through proper electrical design and material selection, the backplane can also improve the anti-interference capability of the power valve control device. This helps reduce the impact of external electromagnetic interference on the internal components of the power valve control device, ensuring the stable operation of the system.

[0139] In one related solution, a system for identifying hardware version information is provided, including a hardware system identification unit and a protective power valve control device. The hardware system identification unit outputs multiple sets of status variables, and the software implements the definition of the software version and the hardware version. By reading the values ​​of the status variables of each board in the power valve control device, the current hardware system version information can be obtained and matched with the software version.

[0140] However, this solution uses pull-up and pull-down resistors to output the hardware version of the information network unit, which cannot identify the hardware type and corresponding slot. That is, it can only identify the hardware version, but not the hardware type or the slot of the hardware board in the power valve control device. This could result in the current slot being occupied by a different board, only with a matching version number, causing the entire system to fail to recognize it correctly. Furthermore, in this solution, software-defined versions cannot accurately and comprehensively correspond to the hardware system.

[0141] Based on this, embodiments of this application provide an electric valve control device. Figure 1 Schematic diagram of the structure of the electric valve control device provided in the embodiments of this application Figure 1 ,like Figure 1 As shown, the device 10 includes: a management board 101, a first board 102, and a backplane 103. The first board 102 includes one or more of the following: an application board, a power board, an I / O general board, an input board, an output board, an interface board, and a data acquisition board. The management board 101 and the first board 102 are respectively inserted into different slots of the backplane 103.

[0142] The first board 102 is used to identify the actual first slot number inserted, and to perform a first verification between the first slot number and the second slot number into which the first board 102 is inserted; if the first verification passes, the first slot number and the first board type of the first board 102 are sent to the management board 101.

[0143] Management board 101 is used to perform a second verification on the first board 102; the second verification includes: verifying the type of the first board with the type of board to which the specified first slot number is inserted, and verifying the first slot number with the third slot number to which the specified first board type is inserted;

[0144] Management board 101 is used to activate each board of the power valve control device 10 to operate the power valve control device 10 if the second verification of each first board 102 passes.

[0145] It is understood that, in this embodiment, when the first board 102 verifies and passes the verification between the actual inserted first slot number and the specified second slot number that allows the board to be inserted, the management board 101 verifies the first board type with the type of board to be inserted into the specified first slot number, and verifies the first slot number with the third slot number to be inserted into the specified first board type. If the verification of each first board 102 passes, the management board 101 activates each board of the power valve control device 10 to operate the power valve control device 10. In other words, the first board 102 first performs a self-test, and then the management board 101 performs a secondary verification of the first board 102. This helps ensure that the software-defined first board 102 matches the actually inserted first board 102, and comprehensively improves the safety and availability of the power valve control device 10 when the configuration of the power valve control device 10 conforms to the predefined functions.

[0146] It should be understood that, in this embodiment, "specifying the second slot number into which the first board 102 is inserted" includes: the slot number specified / predefined / pre-set in the verification procedure of the first board 102 that allows the board to be inserted, i.e., the expected slot number. The first board type of the first board 102 includes the hardware type of the first board 102. "Specifying the third slot number into which the first board type is inserted" includes: the slot number specified / predefined / pre-set in the verification procedure of the management board 101 that allows the board to be inserted, i.e., the expected slot number. "Specifying the board type into which the first slot number is inserted" includes: the hardware type of the board that allows the third slot number to be inserted, specified / predefined / pre-set in the verification procedure of the management board 101, i.e., the expected hardware type.

[0147] In this embodiment, the second slot number and the third slot number are not limited, nor is the relationship between the second slot number and the third slot number limited. In some embodiments, the second slot number and the third slot number are different, and it is determined that the third slot number in the verification program of the management board 101 is incorrect.

[0148] In some embodiments, the management board 101 is used to perform a second verification on the first board 102; the second verification includes: verifying the first board type with the board type to which a specified first slot number is inserted, and verifying the first slot number with the third slot number to which a specified first board type is inserted; including: the management board 101 is used to determine the board type of the first board 102 from a preset mapping table according to the first slot number of the first board 102, and verify the first board type with the board type to which a specified first slot number is inserted; and to determine the third slot number of the first board 102 from the preset mapping table according to the first board type of the first board 102, and verify the first slot number with the third slot number to which a specified first board type is inserted; wherein, the preset mapping table refers to the mapping table between the third slot number of each first board 102 and the corresponding board type of the first board 102.

[0149] In some embodiments, the first board 102, which sends the first slot number and the first board type of the first board 102 to the management board 101, can be implemented through any of the following embodiments 1 to 3:

[0150] Example 1: The first board 102 is used to send the first slot number and the first board type of the first board 102 to the management board 101 via the CAN bus, the backplane Low-Voltage Differential Signaling (LVDS) bus, or other buses. That is, each first board 102 sends the first slot number and the first board type of the first board 102 to the management board 101 via the CAN bus, the backplane LVDS bus, or other buses.

[0151] In some embodiments, such as Figure 2 As shown, the first board 102 is used to send the first slot number and the first board type of the first board 102 to the management board 101 through the backplane LVDS bus 201.

[0152] Example 2: The first board 102 is used to send the first slot number and the first board type of the first board 102 to the management board 101 through the interface between the first board 102 and the management board 101.

[0153] Regarding Embodiment 2, it should be understood that in this embodiment, each first board 102 has a corresponding interface with the management board 101. Each first board 102 sends the first slot number and the first board type to the management board 101 through the corresponding interface with the management board 101; or, two or more first boards share one interface to send the first slot number and the first board type of the corresponding first board 102 to the management board 101.

[0154] Example 3: The first board 102 is used to send the first slot number and the first board type of the first board 102 to the management board 101 via wireless communication.

[0155] In some embodiments, the management board 101 is configured to: identify the actual inserted fourth slot number, and perform a third verification by comparing the fourth slot number with the fifth slot number into which the management board 101 is to be inserted; and perform a second verification on the first board 102 if the third verification passes.

[0156] It is understood that in this embodiment, if the management board 101 verifies and passes the verification between the fourth slot number actually inserted into the management board 101 and the fifth slot number specified for insertion into the management board 101, then the board type of the slot number actually inserted into the first board 102 is verified. This helps ensure compatibility between the management board 101 and its corresponding software code, thereby ensuring the normal operation of the power valve control device 10.

[0157] It should be understood that, in the embodiments of this application, the fifth slot number into which the management board 101 is inserted is the slot number of the slot that is specified / predefined / pre-set in the verification procedure of the management board 101 and that allows the board to be inserted.

[0158] In some embodiments, the second verification passes if: the first board type is consistent with the board type inserted into the specified first slot number, and the first slot number is consistent with the third slot number inserted into the specified first board type.

[0159] It is understood that in this embodiment, the first board type is consistent with the board type inserted in the specified first slot number, and the first slot number is consistent with the third slot number inserted in the specified first board type, indicating that the actually inserted first board 102 is a software-defined first board 102. This is beneficial to ensure that the software-defined first board 102 matches the actually inserted first board 102, and to comprehensively improve the safety and availability of the power valve control device 10 when the configuration of the power valve control device 10 meets the predefined functions.

[0160] In some embodiments, the management board is configured to: send a query instruction to the first board 102 if the third verification passes; the query instruction is configured to query the actual inserted slot number and board type; the first board 102 is configured to: in response to the query instruction, send the actual inserted first slot number and the first board type of the first board 102 to the management board if the first verification passes.

[0161] In some embodiments, the management board 101 is further configured to: control the alarm light of the first board 102 that failed the second verification to output a first alarm signal, and control the alarm light of the management board 101 to output a second alarm signal if the second verification of any first board 102 fails; wherein, the second verification failure includes: the first board type is inconsistent with the board type inserted into the specified first slot number, and / or, the first slot number is inconsistent with the third slot number inserted into the specified first board type.

[0162] It is understood that in this embodiment, if the first board type is inconsistent with the type of board inserted into the specified first slot, and / or the first slot number is inconsistent with the third slot number of the specified first board type, it indicates that the software-defined first board 102 does not match the actually inserted first board 102. Therefore, the management board 101 controls the alarm light of the first board 102 that failed the second verification to output a first alarm signal, and controls the alarm light of the management board 101 to output a second alarm signal. Thus, the first alarm signal from the alarm light of the first board 102 and the second alarm signal from the alarm light of the management board 101 indicate a mismatch between the software-defined first board 102 and the actually inserted first board 102, thereby helping users to promptly detect and resolve the problem of "the software-defined first board 102 not matching the actually inserted first board 102".

[0163] It should be understood that, in the embodiments of this application, there are no limitations on the first alarm signal and the second alarm signal. The first alarm signal may be the same or different.

[0164] In some embodiments, the first alarm signal includes at least one of the following: a signal indicating the flashing frequency of the alarm light of the first board 102, a signal indicating the color of the alarm light of the first board 102, and a signal indicating the brightness of the alarm light of the first board 102. Accordingly, the second alarm signal includes at least one of the following: a signal indicating the flashing frequency of the alarm light of the management board 101, a signal indicating the color of the alarm light of the management board 101, and a signal indicating the brightness of the alarm light of the management board 101.

[0165] In some embodiments, the second verification fails when: the first board type is inconsistent with the board type inserted into the specified first slot number, or the first slot number is inconsistent with the third slot number inserted into the specified first board type; the first alarm signal includes alarm light flashing and / or the alarm light color is a first color, and the second alarm signal includes alarm light flashing and / or the alarm light color is a second color.

[0166] It is understood that in this embodiment, if the first board type is inconsistent with the board type inserted into the specified first slot number, or if the first slot number is inconsistent with the third slot number into which the first board type is inserted, then the first alarm signal includes alarm light flashing and / or the alarm light color being a first color, and the second alarm signal includes alarm light flashing and / or the alarm light color being a second color. Thus, by using the alarm light flashing and / or the alarm light color of the first board 102 and the alarm light flashing and / or the alarm light color of the management board 101 to indicate a mismatch between the software-defined first board 102 and the actual inserted first board 102's board type or slot number, it is beneficial for users to promptly detect and resolve the problem of "the first board type being inconsistent with the board type inserted into the specified first slot number or the first board 102 not matching the actual inserted first board 102's board type or slot number."

[0167] It should be understood that in the embodiments of this application, there are no limitations on the flashing frequency of the alarm light, the first color, and the second color; wherein, the flashing frequency of the alarm light includes: the frequency at which the human eye can perceive the flashing of the alarm light. The first color or the second color can be any color, such as: red, yellow, blue, green, purple, orange, cyan, and other colors derived therefrom; and the first color and the second color can be the same, or the first color and the second color can be different.

[0168] It should be noted that, due to the large number of colors, it is impossible to list all color types here. Therefore, colors not listed in this specification should also be covered within the scope of protection of this application.

[0169] In some embodiments, the first alarm signal includes flashing of an alarm light, and the second alarm signal includes the alarm light being green; or, the first alarm signal includes flashing of an alarm light at a first frequency, and the second alarm signal includes flashing of an alarm light at a second frequency, wherein the first frequency is not equal to the second frequency; or, the first alarm signal includes flashing of an alarm light at a first frequency and the alarm light being green, and the second alarm signal includes flashing of an alarm light at a first frequency and the alarm light being yellow; or, the first alarm signal includes flashing of an alarm light at a first frequency and the alarm light being green, and the second alarm signal includes flashing of an alarm light at a second frequency and the alarm light being green; or, the first alarm signal includes flashing of an alarm light at a first frequency and the alarm light being green, and the second alarm signal includes flashing of an alarm light at a first frequency and the alarm light being yellow.

[0170] In some embodiments, the second verification fails when: the first board type is inconsistent with the board type inserted into the specified first slot number, and the first slot number is inconsistent with the third slot number inserted into the specified first board type; the first alarm signal includes the alarm light being lit and / or the alarm light color being a third color, and the second alarm signal includes the alarm light being lit and / or the alarm light color being a fourth color.

[0171] It is understood that in this embodiment, the first board type is inconsistent with the type of board inserted into the specified first slot, and the first slot number is inconsistent with the third slot number into which the first board type is inserted. Therefore, the first alarm signal includes the alarm light being lit and / or the alarm light color being a third color, and the second alarm signal includes the alarm light being lit and / or the alarm light color being a fourth color. Thus, by using the alarm light lighting and / or the alarm light color of the first board 102 and the alarm light lighting and / or the alarm light color of the management board 101 to indicate a mismatch between the software-defined first board type and the actually inserted board type, and between the first slot number and the actually inserted second slot number, it is beneficial for users to promptly detect and resolve the problem of "the software-defined first board type being inconsistent with the type of board inserted into the specified first slot and the software-defined first slot number being inconsistent with the third slot number into which the first board type is inserted."

[0172] It should be understood that in the embodiments of this application, the third color and the fourth color are not limited. The third color and the fourth color can be any color, such as red, yellow, blue, green, purple, orange, cyan, and other colors derived therefrom; and the third color and the fourth color can be the same, or the third color and the fourth color can be different.

[0173] It should be noted that, due to the large number of colors, it is impossible to list all color types here. Therefore, colors not listed in this specification should also be covered by the protection scope of this application.

[0174] In some embodiments, the first alarm signal includes an alarm light being illuminated, and the second alarm signal includes the alarm light being green; or, the first alarm signal includes the alarm light being yellow, and the second alarm signal includes the alarm light being green; or, the first alarm signal includes the alarm light being illuminated and the alarm light being green, and the second alarm signal includes the alarm light being illuminated and the alarm light being yellow.

[0175] In some embodiments, the management board 101 is used to: control the alarm light of the management board 101 to output a third alarm signal when the third verification fails; wherein, the failure of the third verification includes: the fourth slot number is inconsistent with the fifth slot number into which the management board 101 is inserted.

[0176] It is understood that in this embodiment, if the fourth slot number actually inserted into the management board 101 is inconsistent with the fifth slot number specified for insertion, the management board 101 controls its alarm light to output a third alarm signal. This allows users to promptly detect and resolve the issue of "incorrect slot number inserted into the management board 101" through the third alarm signal from the management board's alarm light, rather than misjudging it as a failure of the second verification of the first board when both the management board and the first board fail their self-tests.

[0177] It should be understood that the third alarm signal is not limited in the embodiments of this application. In some embodiments, the third alarm signal includes at least one of the following: a signal indicating the flashing frequency of the alarm light of the management board 101, a signal indicating the color of the alarm light of the management board 101, and a signal indicating the brightness of the alarm light of the management board 101.

[0178] In some embodiments, the third alarm signal includes the alarm light being illuminated; or, the third alarm signal includes the alarm light being white; or, the third alarm signal includes the alarm light being illuminated and the alarm light being pink.

[0179] In some embodiments, the first board 102 is configured to control the alarm light of the first board 102 to output a fourth alarm signal if the first verification fails; wherein, the first verification failure includes: the first slot number is inconsistent with the second slot number into which the first board 102 is to be inserted.

[0180] It is understood that in this embodiment, if the actual first slot number into which the first board 102 is inserted is inconsistent with the specified second slot number into which the first board 102 is inserted, the alarm light of the first board 102 will be controlled to output a fourth alarm signal. This allows users to promptly detect and resolve the issue of "the first board 102 being inserted into an incorrect slot number" through the alarm light of the first board, rather than misjudging it as a failure of the second verification of the first board when both the management board and the first board's self-test fail.

[0181] It should be understood that the fourth alarm signal is not limited in the embodiments of this application. In some embodiments, the fourth alarm signal includes at least one of the following: a signal indicating the flashing frequency of the alarm light of the first board 102, a signal indicating the color of the alarm light of the first board 102, and a signal indicating the brightness of the alarm light of the first board 102.

[0182] In some embodiments, the fourth alarm signal includes an alarm light being illuminated; or, the fourth alarm signal includes an alarm light that is purple; or, the fourth alarm signal includes both an alarm light being illuminated and an alarm light that is red.

[0183] This application provides a management board, which is used to: receive a first slot number and a first board type from a first board; wherein the first slot number is the actual slot number in which the first board is inserted into the backplane of the power valve control device; the first slot number and the first board type are sent to the management board by the first board after a first verification is performed between the first slot number and a specified second slot number into which the first board is inserted, and the verification passes; wherein the first board includes one or more of the following: application board, power board, I / O general board, input board, output board, interface board, and acquisition board; perform a second verification on the first board; the second verification includes: verifying the first board type against the board type into which the specified first slot number is inserted, and verifying the first slot number against a third slot number into which the specified first board type is inserted; and, if the second verification of each first board passes, start each board of the power valve control device to run the power valve control device.

[0184] It is understood that, in this embodiment, the first board, after verifying and passing the check between the actually inserted first slot number and the specified second slot number that allows the board to be inserted, sends the first slot number and the first board type to the management board. The management board verifies the received first board type against the type of board inserted into the specified first slot number, and verifies the received first slot number against the third slot number that allows the first board type to be inserted. If the verification of each first board passes, the management board starts each board of the power valve control device to run the power valve control device. That is, the first board first performs a self-test, and then the management board performs a secondary verification on the first board. This helps to ensure that the software-defined first board matches the actually inserted first board, thereby comprehensively improving the safety and availability of the power valve control device when the configuration of the power valve control device meets the predefined functions.

[0185] This application provides a method for starting a power valve control device, which is applied to a management board. Figure 3 A flowchart illustrating the method for starting a power valve control device provided in this application embodiment. Figure 1 ,like Figure 3 As shown, the method includes the following steps S301 to S303:

[0186] S301, Receive the first slot number and the first card type of the first card sent by the first card; wherein, the first slot number is the actual slot number of the slot in which the first card is inserted into the back panel of the power valve control device; the first slot number and the first card type are sent to the management card by the first card after the first card performs a first verification with the specified second slot number into which the first card is inserted and passes the verification.

[0187] The first board includes one or more of the following: application board, power board, I / O general board, input board, output board, interface board, and data acquisition board.

[0188] S302, perform a second verification on the first board; the second verification includes: verifying the type of the first board with the type of board to which the specified first slot number is inserted, and verifying the first slot number with the third slot number to which the specified first board type is inserted;

[0189] S303, if the second verification of each first board passes, start each board of the power valve control device to run the power valve control device.

[0190] It is understood that, in this embodiment, the first board, after verifying and passing the check between the actually inserted first slot number and the specified second slot number that allows the board to be inserted, sends the first slot number and the first board type to the management board. The management board verifies the received first board type against the type of board inserted into the specified first slot number, and verifies the received first slot number against the third slot number that allows the first board type to be inserted. If the verification of each first board passes, the management board starts each board of the power valve control device to run the power valve control device. That is, the first board first performs a self-test, and then the management board performs a secondary verification on the first board. This helps to ensure that the software-defined first board matches the actually inserted first board, thereby comprehensively improving the safety and availability of the power valve control device when the configuration of the power valve control device meets the predefined functions.

[0191] Based on this, the following will describe an exemplary application of the embodiments of this application in a practical application scenario.

[0192] This application provides a method for starting a power valve control device. In some embodiments, each board (including a management board and a first board) has its own defined hardware type (i.e., an example of a board type) and a defined slot number (if the board is the first board, then the slot number is an example of the third slot number or the second slot number; if the board is a management board, then the slot number is an example of the fifth slot number). Step 1: After each board is inserted into the device (i.e., an example of a power valve control device), it automatically obtains its actual hardware type (i.e., an example of the first board type) and actual slot number (if the board is the first board, then the slot number is an example of the first slot number; if the board is a management board, then the slot number is an example of the fourth slot number). It then performs a slot number self-check, comparing the actual inserted slot number with the prescribed inserted slot number. If the comparison fails, an alarm light signal is output (if the board is the first board, then the alarm light signal is an example of the fourth alarm light signal; if the board is a management board, then the alarm light signal is an example of the third alarm light signal). If the comparison succeeds, it proceeds to Step 2. The second step involves the main Central Processing Unit (CPU) board (an example of a management board) collecting the actual hardware type and actual slot number (an example of the first slot number) of all other boards (an example of the first board). The main CPU board (an example of a management board) sends a command to query the actual hardware type and actual slot number of the other boards. After receiving the query command, the other boards feed back their actual hardware type and actual slot number to the main CPU board through the LVDS bus on the backplane. The main CPU board compares the received actual hardware type and actual slot number with the specified hardware type and specified slot number. If the comparison is correct, the verification is successful. If the comparison fails, the main CPU board will control the alarm light to output an alarm signal (an example of the first alarm signal) and the alarm light of the board that failed the verification will output an alarm signal (an example of the second alarm signal). The alarm signal is a flashing alarm light.

[0193] If the actual hardware type and slot number of all other boards are successfully verified, the system operates normally. If only one of the actual hardware type or slot number is successfully verified, the main CPU board's alarm light flashes, and it also controls the alarm lights of the boards that failed the verification to flash. If both the actual hardware type and slot number fail to be verified, the main CPU board's alarm light remains constantly on, and it also controls the alarm lights of the other boards to remain constantly on. After a verification failure, the problem is investigated, and then the verification is repeated until it succeeds.

[0200] S406, the interface board, acquisition board, input board, output board, general board, and power board provide feedback on their actual hardware type and actual slot number based on the received query command;

[0206] S501, the management board checks whether it is inserted into the correct slot; if correct, proceed to step S502, otherwise, proceed to step S503.

[0213] This application provides a power secondary control and protection device (i.e., an example of a power valve control device). Figure 6 Schematic diagram of the structure of the electric valve control device provided in the embodiments of this application Figure 3 ,like Figure 6 As shown, the device 10 includes: a power board 601, an interface board 602, a main CPU board 101, a slave CPU board 603, an input board 604, and an output board 605. Each board is connected and fixed to the backplane via VPX terminals. All the boards in the device form a system architecture, which can determine whether the device system can operate normally by verifying the actual hardware type and slot number of all the boards in the device. The device 10 also includes: a general-purpose I / O board and a backplane.

[0214] Figure 7 Schematic diagram of the structure of the electric valve control device provided in the embodiments of this application Figure 4 ,like Figure 7 As shown, the external pull-up and pull-down resistors of the MCU 701 and FPGA chip 702 on the board can determine the hardware type of this board. The MCU 701 can read the slot number of the board after power-on.

[0215] Figure 8 Schematic diagram of the structure of the electric valve control device provided in the embodiments of this application Figure 5 ,like Figure 8 As shown, the backplane VPX801 can determine the actual slot number of the other boards 802 and upload it to the FPGA of the other boards 802 for identification and verification.

[0216] Device 10 also determines the verification architecture for the hardware type and slot number:

[0217] 1. The main CPU board obtains the expected hardware type and expected slot number of all boards in the entire device 10 that need to be verified;

[0218] 2. Manage boards, application boards, general I / O boards, interface boards, input boards, and output boards to obtain the actual hardware type and actual slot number of the board;

[0219] 3. The management board collects the actual hardware type and slot number of the application board, general I / O board, interface board, input board, and output board; among them, the main CPU board contains identified information such as multiple processes, multiple drivers, FPGA, hardware, firmware, and CFCs.

[0220] 4. All processes on the management board (except the version management process), application board, general I / O board, interface board, input board, and output board are only allowed to continue running after receiving a startup command;

[0221] 5. The management board verifies the hardware type and slot number of all boards in the entire device by comparing the actual version with the expected version. If the hardware type or slot number of any board fails the verification, the management board is notified to control the alarm light to flash, as well as to control the alarm light of the boards that failed the verification to flash. If the verification of each board is successful, a start command is issued.

[0222] Depend on Figure 8 It can be seen that the hardware of device 10 uses pull-up and pull-down resistors to preset the expected hardware type and expected slot number of the board. The expected hardware type of the board is determined by using pull-up and pull-down resistors on the MCU pins. After the MCU powers on, it reads the expected slot number and expected board type, and then sends these information to the FPGA via the SPI / UART bus. The slot number is represented by 5-bit IO (00000-11111), supporting a total of 32 slots. The board type is represented by 4-bit IO (0000-1111), supporting 16 different types of boards. The software reads the slot information and board type using binary encoding. The actual slot number of the board is uploaded to each board via the backplane. The FPGA identifies the slot number of its own board and uploads the actual hardware type and actual slot number information to the CPU board via the backplane LVDS bus. Two comparisons can be performed, ensuring complete consistency and communication with the CPU board.

[0223] This application proposes a verification architecture based on hardware type and slot number (i.e., an example of a power valve control device) and a verification method based on hardware type and slot number (i.e., an example of a method for starting a power valve control device). This architecture and method ensure the compatibility of the hardware board with the entire device system, guarantee hardware and software compatibility, and ensure that the device's system configuration conforms to the initial design, comprehensively improving the device's safety and availability. Furthermore, this architecture and method are simple to understand, have broad coverage, and offer high accuracy in slot number and type identification verification. They offer high usability in the power control and protection industry.
