Description

Technical Field

[0001] This application relates to the field of transformation control equipment technology, and in particular to a multi-protection method, device and computer equipment for transformation control equipment. Background Technology

[0002] As the central control device in the converter control system, the conversion control equipment converts and transforms the voltage and current signals input from the front end. It then outputs control signals to the back-end external devices via a switch output interface and a PWM (Pulse Width Modulation Interface) interface. The back-end devices then perform the prescribed actions after signal conversion. Therefore, the conversion control equipment plays a crucial role in the converter control system. If the conversion control equipment malfunctions or makes calculation errors, it will pose a significant threat to the safety and reliability of the back-end devices. Therefore, improving the effectiveness of operational protection against malfunctions is a key research focus.

[0003] Traditional protection measures for converter control equipment typically include circuit breaker protection, contactor protection, overload protection, undervoltage protection, and overcurrent protection. However, these methods all detect and control the input signals from the perspective of hardware circuits and electrical components, thus protecting the equipment. This results in limited protection measures, insufficient protection effectiveness, and an inability to address software faults, ultimately leading to poor control and protection performance for the converter control equipment. Summary of the Invention

[0022] The back-end input signal is split into input data of each signal criterion type, and based on the input data of each signal criterion type, the coprocessor unit determines whether the back-end input signal meets the third protection judgment condition.

[0064] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0065] The multi-protection method for a transformation control device provided in this application embodiment can be applied to the application environment of a multi-protection system for a transformation control device. For example, Figure 1 As shown, the system includes a main processor (DSP, Digital Signal Processor), a coprocessor (FPGA, Field-Programmable Gate Array), an IC (Integrated Circuit) comparator module, a hysteresis protection circuit module, and an AD (Analog-to-Digital Converter) acquisition chip circuit. This system can be applied to terminals, servers, or systems that include both terminals and servers, and is implemented through interaction between the terminals and servers. The terminals can be, but are not limited to, various personal computers, laptops, and mid-range computers. The terminals, by implementing multiple protection methods, provide fault identification, fault isolation, fault alarm, and fault control functions for the conversion control equipment during operation. Based on the existing hardware protection measures of the conversion control equipment, a multi-faceted and comprehensive software protection strategy provides all-round protection for the conversion control equipment in the event of software faults. This allows the conversion control equipment to be protected from both hardware and software levels, avoiding the problems of single protection measures and limited protection effects, thereby comprehensively improving the control and protection effect of the conversion control equipment.

[0066] In one exemplary embodiment, such as Figure 2 As shown, a multi-protection method for a conversion control device is provided. Taking the application of this method to a terminal as an example, the method includes the following steps S201 to S203. Wherein:

[0067] Step S201: Obtain the front-end voltage input information, back-end input signal, and software running status information of the conversion control device, and based on the front-end voltage input information, identify the abnormal status information of the conversion control device through the comparison circuit unit and the hysteresis protection circuit unit.

[0068] In this embodiment, when the front-end device inputs voltage information to the conversion control device, the terminal collects the front-end voltage input information of the conversion control device. Then, the terminal, through the main processor (DSP) unit, collects the software running status information of the conversion control device in real time. Finally, the terminal detects and monitors the back-end status feedback input signal in real time through the coprocessor FPGA firmware to obtain the back-end input signal. In this scheme, the main processor unit is the main processor (DSP), the coprocessor unit is the coprocessor FPGA firmware, the comparison circuit unit is an IC comparison circuit, the hysteresis protection circuit unit is a hysteresis protection circuit, and the signal conversion unit is an AD acquisition chip. Then, based on the front-end voltage input information, the terminal identifies the abnormal status information of the conversion control device through the comparison circuit unit and the hysteresis protection circuit unit. This abnormal status information is the result of abnormal identification of the front-end voltage input information.

[0069] Step S202: Identify the voltage data information corresponding to the front-end voltage input information, and generate an operating status indication signal through the main processor unit based on the software operating status information.

[0070] In this embodiment, the terminal identifies the voltage data information corresponding to the front-end voltage input information and generates a running status indication signal through the main processor unit based on the software running status information. The specific generation process will be described in detail later. This running status indication signal is used to instruct the coprocessor unit to perform signal detection, thereby determining whether there is any abnormality in the software running status.

[0071] Step S203: Based on voltage data information, operating status indication signal, and back-end input signal, the coprocessor unit identifies the abnormal detection results of the conversion control device, and generates output signal control information of the conversion control device based on the abnormal status information and abnormal detection results.

[0072] In this embodiment, the terminal, based on voltage data, operating status indication signals, and backend input signals, uses a coprocessor unit to identify the anomaly detection results of the conversion control device. Based on the anomaly status information and the anomaly detection results, it generates output signal control information for the conversion control device. The anomaly detection results include the results obtained by detecting the voltage data, operating status indication signals, and backend input signals respectively. The specific generation process will be explained in detail later.

[0073] Based on the above scheme, by setting up multiple protection methods, the converter control equipment is provided with functions such as fault identification, fault isolation, fault alarm, and fault control during operation. Thus, on the basis of the existing hardware protection measures of the converter control equipment, a multi-angle and comprehensive software protection strategy is adopted to provide comprehensive protection for the converter control equipment in the event of software failure. This enables the converter control equipment to be protected from both hardware and software protection levels, avoiding the problems of single protection measures and limited protection effects, thereby comprehensively improving the control and protection effect of the converter control equipment.

[0074] Optionally, based on the front-end voltage input information, the abnormal state information of the conversion control device is identified through a comparison circuit unit and a hysteresis protection circuit unit, including: identifying the voltage input signal and the current input signal based on the front-end voltage input information; identifying the signal deviation value of the voltage input signal through the comparison circuit unit, and generating the first abnormal state information corresponding to the signal deviation value when the signal deviation value is greater than the signal deviation threshold; comparing the current input signal with the threshold current signal through the hysteresis protection circuit unit to obtain the comparison result of the current input signal, and using the comparison result as the second abnormal state information when the comparison result is an abnormal comparison result; and using the first abnormal state information and the second abnormal state information as the abnormal state information of the conversion control device.

[0075] In this embodiment, the terminal identifies the voltage input signal and the current input signal based on the front-end voltage input information. Then, the terminal identifies the signal deviation value of the voltage input signal through a comparison circuit unit, and generates first abnormal state information corresponding to the signal deviation value when the signal deviation value is greater than a signal deviation threshold. The terminal presets a signal deviation threshold, and determines that the voltage input signal is abnormal when the signal deviation value is greater than the signal deviation threshold.

[0076] Then, the terminal compares the current input signal with the threshold current signal through the hysteresis protection circuit unit to obtain the comparison result of the current input signal. If the comparison result is abnormal, it is used as the second abnormal state information. This abnormal comparison result is that the current input signal exceeds the signal range corresponding to the threshold current signal. Finally, the terminal uses the first and second abnormal state information as the abnormal state information of the conversion control device.

[0077] Based on the above scheme, the front-end voltage input signal is identified by comparing the circuit unit and the hysteresis protection circuit unit, which improves the identification efficiency and the accuracy of anomaly identification.

[0078] Optionally, identifying the voltage data information corresponding to the front-end voltage input information includes: generating a voltage data signal corresponding to the voltage input signal through a signal conversion unit based on the voltage input signal corresponding to the front-end voltage input information; and using the voltage data signal as the voltage data information corresponding to the front-end voltage input information.

[0079] In this embodiment, the terminal generates a voltage data signal corresponding to the voltage input signal based on the voltage input signal corresponding to the front-end voltage input information through a signal conversion unit. Then, the terminal uses the voltage data signal as the voltage data information corresponding to the front-end voltage input information. Specifically, the terminal configures and executes the AD acquisition voltage monitoring method criteria as follows: Figure 3 As shown, a) Configure which front-end voltage input channels to monitor, any number of channels from 1 to 16 can be configured; b) Configure the upper and lower threshold limits of the channel to be monitored, supporting individual configuration for each channel; c) Configure the upper and lower threshold limit deviation values ​​of the channel to be monitored, supporting individual configuration for each channel; d) Configure the voltage filtering time of the channel to be monitored, supporting individual configuration for each channel.

[0080] Based on the above scheme, by configuring the front-end voltage input signal, voltage data information corresponding to the voltage input signal is generated, thereby improving the accuracy of voltage data information recognition.

[0081] Optionally, based on the software running status information, the main processor unit generates a running status indication signal, including: based on the software running status information, identifying the level change distribution information of the conversion control device, and breaking down the level change distribution information into sub-level change distribution information corresponding to each cycle; through the main processor unit, identifying the abnormal level information in each sub-level change distribution information, and generating a running status indication signal based on the abnormal level information corresponding to each cycle.

[0082] In this embodiment, the terminal identifies the level change distribution information of the transformation control device based on software running status information, and breaks down the level change distribution information into sub-level change distribution information corresponding to each cycle. The main processor unit then identifies abnormal level information in each sub-level change distribution information and generates a running status indication signal based on the abnormal level information corresponding to each cycle. Specifically, as shown... Figure 4The diagram shows the criterion configuration and execution flowchart of the main processor software running status monitoring method. The configuration information for the terminal to configure the coprocessor FPGA firmware through the XINTF bus (External Interface) includes: a) configuring the detection cycle, i.e. how often the FPGA firmware detects; b) configuring the GPIO (General-purpose input / output) high-level duration T1; c) configuring the GPIO high-level duration T2.

[0083] Based on the above scheme, the identification of operation status indication signals is improved by using configuration information, thereby enhancing the comprehensiveness and accuracy of the identification.

[0084] Optionally, based on voltage data information, operating status indication signals, and back-end input signals, the coprocessor unit identifies the abnormal detection results of the conversion control equipment, including: based on the voltage data information, the coprocessor unit detects whether the voltage data information meets the first protection judgment condition, and based on the operating status indication signal, the coprocessor unit detects whether the operating status indication signal meets the second protection judgment condition; the back-end input signal is split into input data of various signal criterion types, and based on the input data of each signal criterion type, the coprocessor unit determines whether the back-end input signal meets the third protection judgment condition; when the voltage data information meets the first protection judgment condition, or the operating status indication signal meets the second protection judgment condition, or the back-end input signal meets the third protection judgment condition, the coprocessor unit generates the abnormal detection results of the conversion control equipment.

[0085] In this embodiment, the terminal, based on voltage data information, uses a coprocessor unit to detect whether the voltage data information meets the first protection judgment condition, and based on the operating status indication signal, uses the coprocessor unit to detect whether the operating status indication signal meets the second protection judgment condition. For example... Figure 3 As shown, the terminal monitors the voltage data acquired by the AD converter in real time based on the criteria configuration information of the conversion control software through the coprocessor FPGA firmware; then, it identifies anomalies and obtains the judgment result of the first protection judgment condition. Next, the terminal notifies the coprocessor FPGA firmware to start monitoring via the XINTF bus through the conversion control software; subsequently, the terminal coprocessor FPGA firmware monitors the GPIO level status according to the configured cycle based on the criteria configuration information of the conversion control software, and obtains the judgment result of the second protection judgment condition.

[0086] Next, the terminal breaks down the backend input signal into input data for each signal criterion type, and based on the input data for each signal criterion type, uses the coprocessor unit to determine whether the backend input signal meets the third protection judgment condition. Specifically, for example... Figure 5 The diagram illustrates the criterion configuration and execution flow of the backend device feedback status monitoring method. The terminal configures the criteria in the coprocessor FPGA firmware via the XINTF bus: a) configuring which backend device feedback status channels to monitor (any number from 1 to 16 channels can be configured); b) configuring the abnormal level of the monitored channel (i.e., high-level abnormality or low-level abnormality), supporting individual configuration for each channel; c) configuring the level filtering duration of the monitored channel, also supporting individual configuration for each channel. Then, based on the criterion configuration information from the conversion control software, the terminal monitors the status data fed back by the backend devices in real time through the coprocessor FPGA firmware, obtaining the judgment result of the third protection judgment condition. Finally, when the voltage data information meets the first protection judgment condition, or the operating status indication signal meets the second protection judgment condition, or the backend input signal meets the third protection judgment condition, the terminal generates the abnormal detection result of the conversion control device through the coprocessor unit.

[0087] Based on the above scheme, anomaly detection is improved by detecting anomalies from three perspectives: voltage data information, operating status indication signals, and back-end input signals. This enhances the effectiveness and comprehensiveness of anomaly detection.

[0088] Optionally, based on the abnormal state information and the abnormal detection results, output signal control information of the conversion control device is generated, including: identifying the generation time point of the abnormal state information and the generation time point of the abnormal detection results; generating a signal control sequence of the conversion control device based on the generation time point of the abnormal state information and the generation time point of the abnormal detection results; and generating output signal control information of the conversion control device according to each time point in the signal control sequence through a preset signal control program.

[0089] In this embodiment, the terminal identifies the generation time of the abnormal state information and the generation time of the abnormal detection result. Then, based on the generation time of the abnormal state information and the generation time of the abnormal detection result, the terminal generates a signal control sequence for the conversion control device. Finally, the terminal generates output signal control information for the conversion control device according to each time point in the signal control sequence using a preset signal control program. Specifically, the output signal control information is a signal to shut down the output of the conversion control device.

[0090] Based on the above scheme, by controlling the output signal according to the generation sequence at specific times, the control efficiency of the output signal is improved.

[0091] This application also provides an example of multiple protections for a transformation control device, such as... Figure 6 As shown, the specific processing procedure includes the following steps:

[0092] Step S601: Obtain the front-end voltage input information, back-end input signal, and software running status information of the conversion control device.

[0093] Step S602: Based on the front-end voltage input information, identify the voltage input signal and the current input signal.

[0094] Step S603: By comparing the circuit unit, the signal deviation value of the voltage input signal is identified, and when the signal deviation value is greater than the signal deviation threshold, the first abnormal state information corresponding to the signal deviation value is generated.

[0095] Step S604: The current input signal is compared with the threshold current signal through the hysteresis protection circuit unit to obtain the comparison result of the current input signal. If the comparison result is an abnormal comparison result, the comparison result is used as the second abnormal state information.

[0096] Step S605: The first abnormal state information and the second abnormal state information are used as the abnormal state information of the transformation control device.

[0097] Step S606: Based on the voltage input signal corresponding to the front-end voltage input information, a voltage data signal corresponding to the voltage input signal is generated through a signal conversion unit.

[0098] Step S607: The voltage data signal is used as the voltage data information corresponding to the front-end voltage input information.

[0099] Step S608: Based on the software running status information, identify the level change distribution information of the conversion control device, and break down the level change distribution information into sub-level change distribution information corresponding to each cycle.

[0100] Step S609: The main processor unit identifies the abnormal level information in the distribution information of each sub-level change, and generates a running status indication signal based on the abnormal level information corresponding to each cycle.

[0101] Step S610: Based on the voltage data information, the coprocessor unit detects whether the voltage data information meets the first protection judgment condition, and based on the operating status indication signal, the coprocessor unit detects whether the operating status indication signal meets the second protection judgment condition.

[0102] Step S611: The back-end input signal is split into input data of each signal criterion type, and based on the input data of each signal criterion type, the coprocessor unit determines whether the back-end input signal meets the third protection judgment condition.

[0103] In step S612, when the voltage data information meets the first protection judgment condition, or the operating status indication signal meets the second protection judgment condition, or the back-end input signal meets the third protection judgment condition, the abnormal detection result of the conversion control device is generated through the coprocessor unit.

[0104] Step S613: Identify the time point at which the abnormal state information is generated and the time point at which the abnormal detection result is generated.

[0105] Step S614: Based on the generation time of the abnormal state information and the generation time of the abnormal detection result, generate the signal control sequence of the transformation control device.

[0106] Step S615: By using a preset signal control program, output signal control information of the conversion control device is generated according to each time point in the signal control sequence.

[0108] Based on the same inventive concept, this application also provides a multi-protection device for a transformation control device to implement the multi-protection method for the transformation control device described above. The solution provided by this device is similar to the solution described in the above method. Therefore, the specific limitations in one or more embodiments of the multi-protection device for a transformation control device provided below can be found in the limitations of the multi-protection method for the transformation control device described above, and will not be repeated here.
