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

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

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

[0071] Step S203, based on the voltage data information, the operation status indication signal, and the back-end input signal, the abnormal detection result of the conversion control device is identified through the coprocessor unit, and based on the abnormal status information and the abnormal detection result, the output signal control information of the conversion control device is generated.

[0072] In this embodiment, the terminal identifies the abnormality detection result of the conversion control device through the coprocessor unit based on the voltage data information, the operation status indication signal, and the back-end input signal, and generates the output signal control information of the conversion control device based on the abnormal status information and the abnormality detection result. The abnormality detection result includes the detection results obtained by detecting the voltage data information, the operation status indication signal, and the back-end input signal respectively. The specific generation process will be described in detail later.

[0073] Based on the above scheme, by setting up multiple protection methods, the functions of fault identification, fault isolation, fault alarm, fault control and the like are provided for the conversion control equipment during operation. Thus, on the basis of the existing hardware protection measures of the conversion control equipment, a multi-angle and comprehensive software protection strategy is adopted to provide all-round protection for the conversion control equipment in the event of software fault anomalies. The conversion control equipment can be fully protected from both hardware protection and software protection levels, thus avoiding the problems of single protection measures and limited protection effects, thereby comprehensively improving the control and protection effects of the conversion control equipment.

[0074] Optionally, based on the front-end voltage input information, abnormal state information of the conversion control device is identified through a comparison circuit unit and a hysteresis protection circuit unit, including: based on the front-end voltage input information, a voltage input signal and a current input signal are identified; through a comparison circuit unit, a signal deviation value of the voltage input signal is identified, and when the signal deviation value is greater than a signal deviation threshold, first abnormal state information corresponding to the signal deviation value is generated; through a hysteresis protection circuit unit, the current input signal is compared with a threshold current signal to obtain a comparison result of the current input signal, and when the comparison result is an abnormal comparison result, the comparison result is used as the second abnormal state information; the first abnormal state information and the second abnormal state information are used as 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 the comparison circuit unit, and generates the first abnormal state information corresponding to the signal deviation value when the signal deviation value is greater than the signal deviation threshold. Among them, the terminal presets the 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, and when the comparison result is an abnormal comparison result, the comparison result is used as the second abnormal state information. Among them, the abnormal comparison result is that the current input signal is greater than the signal range corresponding to the threshold current signal. Finally, the terminal uses the first abnormal state information and the 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 respectively through the comparison circuit unit and the hysteresis protection circuit unit, thereby improving the recognition efficiency and the accuracy of abnormality recognition.

[0078] Optionally, identifying voltage data information corresponding to the front-end voltage input information includes: based on the voltage input signal corresponding to the front-end voltage input information, generating a voltage data signal corresponding to the voltage input signal through a signal conversion unit; 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 through a signal conversion unit based on the voltage input signal corresponding to the front-end voltage input information. Then, the terminal uses the voltage data signal as the voltage data information corresponding to the front-end voltage input information. Specifically, the terminal collects voltage monitoring method according to the configuration and execution process as shown in FIG. Figure 3 As shown in the figure, a) configure which front-end voltage input channels to monitor, and any number of channels from 1 to 16 can be configured; b) configure the upper and lower threshold limits of the channels to be monitored, and support separate configuration for each channel; c) configure the upper and lower threshold limit deviation values ​​of the channels to be monitored, and support separate configuration for each channel; d) configure the voltage filter duration of the channels to be monitored, and support separate configuration for each channel.

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

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

[0082] In this embodiment, the terminal identifies the level change distribution information of the conversion control device based on the software operation status information, and splits the level change distribution information into sub-level change distribution information corresponding to each period; the abnormal level information in each sub-level change distribution information is identified through the main processor unit, and based on the abnormal level information corresponding to each period, the operation status indication signal is generated through the main processor unit. Specifically, Figure 4The figure shows the configuration and execution flow chart of the main processor software running status monitoring method. The terminal uses the XINTF bus (External Interface) to configure the coprocessor FPGA firmware according to the configuration information, including: a) configuring the detection cycle, that is, how often the FPGA firmware detects; b) configuring the GPIO (General-purpose input / outpu) high level duration T1; c) configuring the GPIO high level duration T2.

[0083] Based on the above solution, the operation status indication signal is identified by using the configuration information, which improves the comprehensiveness and accuracy of the identification.

[0084] Optionally, based on voltage data information, an operating status indication signal, and a back-end input signal, a coprocessor unit is used to identify an abnormality detection result of the conversion control device, including: based on the voltage data information, detecting through the coprocessor unit whether the voltage data information meets a first protection judgment condition, and based on the operating status indication signal, detecting through the coprocessor unit whether the operating status indication signal meets a second protection judgment condition; splitting the back-end input signal into input data of each signal criterion type, and based on the input data of each signal criterion type, judging through the coprocessor unit whether the back-end input signal meets a 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 is used to generate an abnormality detection result of the conversion control device.

[0085] In this embodiment, the terminal detects whether the voltage data information meets the first protection judgment condition through the coprocessor unit based on the voltage data information, and detects whether the operation status indication signal meets the second protection judgment condition through the coprocessor unit based on the operation status indication signal. Figure 3 As shown, the terminal monitors the voltage data collected by the AD in real time through the coprocessor FPGA firmware based on the judgment configuration information of the conversion control software; then identifies the abnormality and obtains the judgment result of the first protection judgment condition. Then, the terminal notifies the coprocessor FPGA firmware through the XINTF bus through the conversion control software to start monitoring; then, the terminal coprocessor FPGA firmware monitors the GPIO level state according to the configured cycle based on the judgment configuration information of the conversion control software, and obtains the judgment result of the second protection judgment condition.

[0086] Then, the terminal splits the back-end input signal into input data of each signal criterion type, and determines whether the back-end input signal meets the third protection judgment condition through the coprocessor unit based on the input data of each signal criterion type. Figure 5 As shown, the judgment configuration and execution process of the back-end device feedback status monitoring method, wherein the terminal configures the judgment criteria of the coprocessor FPGA firmware through the XINTF bus: a) configure which back-end device feedback status channels to monitor, and any number of channels from 1 to 16 can be configured; b) configure the abnormal level of the channel to be monitored (i.e., high level abnormality or low level abnormality), and support separate configuration for each channel; c) configure the level filtering duration of the channel to be monitored, and support separate configuration for each channel; then, the terminal monitors the status data fed back by the back-end device in real time based on the judgment configuration information of the conversion control software through the coprocessor FPGA firmware, and obtains 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 back-end 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 solution, anomaly detection is performed from three angles: voltage data information, operating status indication signal, and back-end input signal, thereby improving the anomaly detection effect and comprehensiveness.

[0088] Optionally, based on the abnormal status information and the abnormal detection result, the output signal control information of the transformation control device is generated, including: identifying the generation time point of the abnormal status information and the generation time point of the abnormal detection result; based on the generation time point of the abnormal status information and the generation time point of the abnormal detection result, generating a signal control sequence of the transformation control device; and generating the output signal control information of the transformation 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 time point at which the abnormal state information is generated and the time point at which the abnormal detection result is generated. Then, the terminal generates a signal control sequence for the conversion control device based on the time point at which the abnormal state information is generated and the time point at which the abnormal detection result is generated. Finally, the terminal generates output signal control information for the conversion control device according to each time point in the signal control sequence through a preset signal control program. The specific output signal control information is to turn off the output signal of the conversion control device.

[0090] Based on the above scheme, the control efficiency of the output signal control is improved by controlling the output signal according to the time point generation order.
