At present, it has become an inevitable trend to use domestic self-chip as the core of safe and controllable protection and measurement and control devices. However, in the process of self-innovation, there is a sharp contradiction between the high-speed iteration of domestic components and the long period of traditional research and development. Each time the core component is upgraded or replaced, it may lead to the re-adaptation and comprehensive testing of device hardware design, driving software and even application software, which is time-consuming, long-period and high-cost, and seriously restricts the development of technology and the upgrading of equipment.

[0019] In order to make the above-mentioned purposes, features and advantages of the present application more apparent and easy to understand, the specific embodiments of the present application will be described in detail below with reference to the drawings in the specification. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor should be within the protection scope of the present application.

[0020] REFERENCE Figure 1 For an embodiment of the present application, a hardware module interchanging method of a universalized protection measurement and control device is provided, comprising: S101, when a new hardware module is inserted into the physical slot of the protection measurement and control device, the new hardware module actively reports metadata to the main processing unit of the device; S102, the configuration management service performs driving matching search in the general driving library based on the acquired metadata, and dynamically loads the corresponding driving program for the new hardware module; S103, the resource configuration manager allocates the system resources required for the new hardware module to run, and initializes and configures the new hardware module through the driving program; S104, based on the initialization configuration, the original data generated by the new hardware module is read, and the original data is converted into standardized engineering value data in combination with the parameters of the new hardware module itself and the configuration parameters, and is published to the real-time data bus; S105, the standardized engineering value data is subscribed and acquired from the real-time data bus, the application logic of the new hardware module is executed, and the automatic recovery of the device function is performed.

[0021] It should be noted that the core target of the application is to realize the "general exchange" of the hardware of the protection measurement and control device, that is, when a hardware module (such as a CPU module, an analog quantity acquisition module, an input / output module) of the device fails or needs to be upgraded, the operation and maintenance personnel can directly pull out the old module and insert the new module in the case of uninterrupted power supply or short-time power failure. The device can automatically identify the new module, load the corresponding driving, reconfigure the resources, and seamlessly restore the application function, without manual complex software configuration or program burning.

[0022] In a preferred embodiment, the new hardware module actively reports metadata to the main processing unit of the device, which includes: The local management chip drives the bottom bus continuously to monitor the state change of the slot, and initiates a reading operation when detecting that a new device is inserted; The insertion action triggers the identity recognition chip of the new hardware module to report the pre-stored metadata of the module to the connected local intelligent management chip to perform data acquisition.

[0023] Specifically, the operation and maintenance personnel insert a new hardware module into the idle slot of the device. After the module is inserted, the power supply, clock and data link layer signal of the backplane bus (such as PCIe or customized high-speed bus) are turned on. The insertion action triggers the identity recognition chip (such as EEPROM or chip internal fixed storage area) on the module to report the pre-stored metadata (Metadata) to the local intelligent management chip (such as FPGA or microcontroller) connected thereto.

[0024] The metadata includes a module identification code, a module type, a manufacturer code, a hardware version number, a firmware version number, and a capability list. The module identification code is a globally unique module identification code. The module type can be an analog input AI, etc. The capability list includes data information such as support of 16 channels, a sampling rate of 4 kHz, an analog-to-digital converter (ADC) precision of 16 bits, etc.

[0025] The local management chip is driven by a bottom layer bus, continuously polls or listens to slot state changes, and initiates a reading operation when a new device is detected to be inserted, reads the above metadata, and temporarily stores the metadata in a shared memory area of a device main CPU module, so as to realize digital collection of hardware identity.

[0026] In a preferred embodiment, matching and loading the driver program include: The configuration management service matches the module identification code and the module type in the metadata, loads an optimal driver if a completely matched driver is found, and attempts to load a general compatible driver of the same type if a completely matched driver is not found.

[0027] Specifically, the step is used to realize module registration and driver matching, and is processed by a configuration management service running on a main CPU. The configuration management service is a software public component, is responsible for automatic discovery, registration, driver matching, and state management of hardware modules, and runs on a main processing unit as a system core service. The configuration management service continuously listens to hardware state registers in a shared memory, i.e., slot state flag bits or interrupt signals. These registers are updated by a bottom layer bus driver. When a new hardware module is inserted, the backboard bus triggers a state change, for example, sets a "new device detection" flag bit. The configuration management service detects the change through a polling or event-driven mechanism. When it is detected that metadata of a new module arrives, the service registers the module identification code, the module type, and the slot number Slot ID to an internal hardware resource table, and marks the module state as "uninitialized".

[0028] Further, the service matches and looks up in the preset general driver library according to the module identification code and the module type. The driver library is a database containing all supporting module driver files. The combination key of "manufacturer ID + model ID" is used for accurate matching. If a completely matched driver is found, the optimal driver is loaded. If a completely matched driver is not found but a driver of the same type (the module types are the same) is found, the general compatible driver is loaded and a warning log is issued, prompting that the driver may not be optimal. In the non-optimal case, the system loads the general compatible driver to ensure the basic function to run, but records the warning information to inform the operation and maintenance personnel. In this case, the module may not be able to exert all the performance or characteristics, and the operation and maintenance personnel need to update the driver library or replace the module subsequently. The matched driver file (a set of function interfaces) is dynamically loaded into the hardware abstraction layer of the system. In the hardware resource table, the state of the new module is updated to "driver ready". This step completes the identification of the hardware identity and the automatic pairing of the software driver.

[0029] In an optional embodiment, the driver matching can also be securely matched and loaded through digital signature authentication. A security authentication mechanism is introduced. When the driver is published, the private key is used to digitally sign the driver file. The trusted root certificate is preset in the system. After the configuration management service finds the candidate driver according to the metadata, the digital signature of the driver file is verified using the preset public key certificate first. If the verification is passed, the driver source is trusted and has not been tampered with, and then the driver loading is completed.

[0030] In another optional embodiment, the driver matching can also be matched through driver containerization. The driver program is converted into a lightweight container and communicates with the main system through a standardized abstract interface. The metadata of the hardware module contains not only the identification code but also the image ID or link of the driver container. The container image information is obtained by parsing the metadata. If the image does not exist, it is downloaded from the specified image warehouse.

[0031] In a preferred embodiment, the system resources required for the new hardware module are allocated, and the new hardware module is initialized and configured through the driver program, including: The loaded driver program applies for the system resources required for the module work to the resource configuration manager. The system resources include memory address space, interrupt request number, and bus address. The parameters of the new hardware module are set through the initialization function of the driver program, and the module state is updated.

[0032] Specifically, the loaded driver applies to the resource configuration manager for system resources required for the module to work normally, including memory mapping, interrupt request, and address configuration. Among them, a fixed memory address space is allocated for the sampling data buffer of the module, and the allocation rule is based on a pre-defined resource mapping table, which dynamically allocates according to the module type and slot position; for example, an analog quantity acquisition module is usually allocated a continuous memory block, the size of which is determined by the number of module channels and the sampling depth, and the rule ensures that the resources are conflict-free and aligned with the bus bandwidth; an interrupt number (IRQ) is allocated for the module to notify the CPU when the sampling is completed or an exception occurs; at the same time, a bus address is configured for the on-board register of the module.

[0033] Further, the driver calls a specific initialization function, which is a standard routine in the driver program, to achieve parameter setting by writing into the configuration register of the module. It can achieve dynamic loading and configuration without the need for system restart or manual intervention. The parameters are set by writing into the configuration register, such as setting the sampling rate, range, filter parameters, etc. The set data and values come from the capability list in the module metadata and the system configuration parameters. For example, the sampling rate is read from the system configuration library according to the maximum value supported by the module and the application requirement (such as the sampling rate required by the protection algorithm), and the range and filter parameters are automatically set according to the factory calibration data of the module. The signal of initialization success is returned to the configuration management service, and then the state of the module in the hardware resource table is updated to "ready". This step allocates necessary software running resources for the hardware module and makes it enter the working state.

[0034] In a preferred embodiment, converting the raw data into standardized engineering value data includes: reading the raw sampling value from the memory buffer, performing data standardization processing on the raw sampling value, and publishing the standardized data to the real-time data bus of the system.

[0035] In a preferred embodiment, the data standardization processing is represented as: wherein, represents the standardized engineering value, represents the raw data value read from the hardware module; represents an offset parameter for eliminating zero error, which is determined by calibration experiment and stored in the identity recognition chip or special storage unit, such as measuring the ADC output value under zero input condition and calculating the average value as Offset for eliminating hardware zero error; represents a gain coefficient parameter for correcting proportional error, which is obtained from the module calibration data by measuring the ADC output by applying a standard signal source and calculating the linear regression coefficient as Gain for correcting signal proportional error; represents the transformer ratio parameter, from the system configuration library of the device (the library is decoupled from the hardware module, and is configured in advance by the user according to the field current transformer / potential transformer (Current Transformer / Potential Transformer) parameter, which ensures that even if the AI module is replaced, the final engineering value is only determined by the external transformer and is irrelevant to the module itself.

[0036] Specifically, the module starts working, converts the analog signal into digital quantity through the ADC chip, and writes the original sampling value into the memory buffer area allocated in step S103 periodically (every sampling period). The original sampling value refers to the unprocessed digital quantity directly read from the ADC, which is usually in the form of an integer, such as a 16-bit signed integer, representing the instantaneous value of the analog signal. The original sampling value RawData is read from the fixed memory buffer area, assuming that the value of a certain channel read is X raw , X raw is converted into an engineering value X eng with a standard physical unit (such as kV, A) through a standardization processing formula. The standardized data is published to the real-time data bus (such as DDS, shared memory message queue, etc.) of the system, and finally an engineering value data stream with no hardware, standardization, and physical unit is output. This step realizes the decoupling of data, so that the upper layer application no longer cares about the difference between the underlying hardware.

[0037] In an optional embodiment, the data standardization processing can use a pre-calibrated lookup table for non-linear mapping. Each module is calibrated at multiple points, the corresponding relationship between the input standard signal and the output original value is recorded, a mapping table from the original value to the engineering value is constructed, and stored in the configuration library of the module. At runtime, the original value is converted into the engineering value by lookup table and interpolation (such as linear interpolation, spline interpolation).

[0038] In another optional embodiment, the data standardization processing can also be standardized based on digital filtering and frequency domain processing. The original sampling sequence is processed by a digital filter, and then Fourier transform is performed to extract the fundamental component or specific harmonic, and finally the effective value, phase, frequency, etc. are calculated.

[0039] In a preferred embodiment, the automatic recovery of device functions includes: The effective value of the data is calculated by the protection algorithm based on the standardized engineering value data, and compared with the set value. If the effective value is greater than the set value, a control instruction is issued through a delay judgment to execute a control action.

[0040] Specifically, the user can automatically subscribe to the current channel data of interest in the real-time data bus, that is, the standardized engineering value data in S104. By executing its inherent protection algorithm, comparison is made with the set value, wherein the protection algorithm can be the effective value of physical quantities such as current, voltage, power, and harmonic, the current effective value is calculated based on the standardized engineering value of the current channel, the voltage effective value is calculated based on the standardized engineering value of the voltage channel, the power is calculated by the product of current and voltage, and the set value is derived from the system protection setting library, which is pre-configured in the system configuration library by the user according to the power grid operation demand.

[0041] The formula for calculating the current effective value in the protection algorithm is represented as: wherein, represents the current effective value, N represents the total number of sampling points in a calculation period, and i(k) represents the current instantaneous value of the kth sampling point.

[0042] When the calculated effective value result is greater than the set value, a control instruction is issued to the backward "DO" module after delay judgment, the delay judgment is realized by using a timer or a counter, in overcurrent protection, the delay judgment is based on inverse time limit or fixed time limit characteristics, the fault time is accumulated by the timer to ensure the accuracy of action; the DO module refers to the control module that is opened, which is used to output digital control signals such as tripping, closing, alarming, locking and the like, for example, in overcurrent protection, a tripping instruction is sent when the current exceeds the set value and the delay time is satisfied, in under-voltage protection, an alarm instruction is sent when the voltage is lower than the set value, and the execution is based on standardized data.

[0043] It should be noted that finally the application can generate fault recording data (record the standardized current and voltage waveform), issue correct tripping signals, drive the circuit breaker to open through the DO module which has also been standardized configured, the protection measurement and control function of the device is completely restored after replacing the hardware module, the design goal of "hardware general exchange" is realized, and during the whole process, the operation and maintenance personnel do not need to intervene in the software process.

[0044] In summary, the application clearly shows how to convert specific hardware modules into abstract and standardized data supply resources through four key links of metadata automatic reporting, intelligent matching driving, resource dynamic allocation, and data standardization processing, so that the upper layer application and the bottom layer hardware are completely decoupled, thereby realizing the true hardware general exchange, greatly improving the operation efficiency, maintainability and reliability of the secondary equipment, and providing a solid technical foundation for building a flexible station-side secondary system.

[0045] The application has the following remarkable beneficial effects: Hardware universal exchange and plug-and-play are realized, different models and versions of hardware modules can realize hot plugging and exchange in the same device through standardized metadata description, automatic driving matching and loading mechanism, which greatly reduces the complexity and cost of spare parts management and on-site operation; The development and test cycle is shortened, the hardware and application are decoupled in the architecture design, the application software is developed based on the unified standardized data interface, and the upper application software does not need to be modified and retested when the hardware module is upgraded, which greatly shortens the development and verification period caused by the iteration of components; The maintainability and reliability of the device are improved, the device function can be quickly restored through simple module replacement operation, the fault outage time is reduced, and the unified driving interface and resource management also improve the stability and reliability of system operation; The data consistency and accuracy are enhanced, the data deviation caused by hardware difference is eliminated through data standardization processing flow, and the data collected by different modules has consistent accuracy and reliability, providing high-quality data basis.
