Description

Technical Field

[0001] This invention relates to the field of power system protection automation technology, and in particular to a method and system for rapid recovery of program faults in relay protection systems. Background Technology

[0002] The real-time performance and reliability of relay protection products for the protection and detection functions of power equipment and power grid equipment are crucial. When a relay protection program malfunctions, on-site personnel need to restart the program, reset relevant parameters, and even restart related circuit boards or the entire device. Each restart of the relay protection system requires support from on-site technicians, consuming significant manpower and resources. Before the relay protection system recovers, the power equipment will be in a dangerous period of unprotection. Enabling relay protection systems to automatically and quickly recover from faults has always been a key goal for relay protection product development teams. Summary of the Invention

[0003] The purpose of this invention is to solve at least one technical problem in the background art and to provide a method and system for rapid recovery of program faults in a relay protection system.

[0004] To achieve the above objectives, the present invention provides a method for rapid recovery of program faults in a relay protection system, comprising: A multi-core heterogeneous system is used in the relay protection system. The multi-core heterogeneous system includes a supervisory system and a real-time system, in which the master core runs the supervisory system and the slave cores run the real-time system. The slave core runs the relay protection program through the real-time system; the master core accesses the slave core's memory area through the supervisory system and supervises the relay protection program running on the real-time system through the supervisory system. The relay protection program running on the real-time system uses the slave core's memory area according to the plan. The real-time system allocates the read-only part and the writable part of the relay protection program content to the read-only area and the writable area of ​​the slave core's memory area, respectively. The monitoring system performs CRC verification on the relay protection program in the read-only area of ​​the slave core; The monitoring system performs a mirror recording of the relay protection program initialization. When the relay protection program encounters a fault and crashes during operation, the monitoring system quickly restores the relay protection program based on the mirror recording of the relay protection program initialization. When the relay protection program is running, if the monitoring system detects that the read-only area of ​​the kernel has been tampered with, it will quickly restore the relay protection program based on the image recording of the relay protection program initialization.

[0005] According to one aspect of the present invention, the read-only area includes: a code segment and a read-only data segment; the writable area includes a writable data segment, a heap, and a stack; The code segment, the read-only data segment, and the writable data segment are addresses allocated when the relay protection program is loaded, while the heap and stack are addresses allocated when the relay protection program is running.

[0006] According to one aspect of the present invention, the monitoring system performs CRC verification on the relay protection program in the read-only area of ​​the slave core, including: The real-time system reads the relay protection program on the Flash memory, stores the code segment and read-only data segment of the relay protection program in the read-only area, and stores the writable data segment in the writable area; The real-time system notifies the monitoring system to perform CRC verification on the relay protection program in the read-only area.

The monitoring system then transfers the relay protection program from the writable area to another backup memory area and notifies the real-time system to run the relay protection program.

[0008] According to one aspect of the present invention, after the relay protection program encounters a fault and crashes during operation, the monitoring system quickly restores the relay protection program based on a mirror recording of the relay protection program initialization, including: When the relay protection program encounters a null pointer exception, an assertion error, or a function return error, it cannot continue execution. The real-time system detects the relay protection program crash and notifies the monitoring system; and / or, when the relay protection program runs away, the monitoring system detects that an error has occurred in the relay protection program. The monitoring system uses the backup memory area to restore the relay protection program of the writable area, allowing the relay protection program to quickly return to the initial configuration state.

[0009] According to one aspect of the present invention, when the relay protection program is running, after the monitoring system detects that the read-only area of ​​the slave core has been tampered with, it quickly restores the relay protection program based on the mirror recording of the relay protection program initialization, including: The monitoring system periodically performs CRC checks on the relay protection program in the read-only area. If the check fails, the monitoring system notifies the real-time system to reload the read-only area, restore the writable area using the contents of the backup memory area, and then notifies the real-time system to run the relay protection program.

[0010] To achieve the above objectives, the present invention also provides a rapid recovery system for program faults in a relay protection system, comprising: A multi-core heterogeneous system configuration module is used in a relay protection system. The multi-core heterogeneous system includes a monitoring system and a real-time system, in which the master core runs the monitoring system and the slave cores run the real-time system. The system function configuration module allows the slave core to run a relay protection program through a real-time system; the master core accesses the slave core's memory area through a monitoring system and monitors the relay protection program running on the real-time system through the monitoring system. The memory allocation module allows the relay protection program running on the real-time system to use the slave core's memory area according to the plan. The real-time system allocates the read-only and writable parts of the relay protection program content to the read-only and writable areas of the slave core's memory area, respectively. The CRC check module is used by the monitoring system to perform CRC checks on the relay protection program in the read-only area of ​​the slave core. The mirror recording module is used by the monitoring system to perform mirror recording of the relay protection program initialization. The first relay protection program recovery module allows the monitoring system to quickly restore the relay protection program based on the mirror recording of the relay protection program initialization after the program encounters a fault and crashes during operation. The second relay protection program recovery module is used to quickly restore the relay protection program based on the image recording of the relay protection program initialization after the monitoring system detects that the read-only area of ​​the slave core has been tampered with during the operation of the relay protection program.

[0011] To achieve the above objectives, the present invention also provides an electronic device, including a processor, a memory, and a computer program stored in the memory and executable on the processor. When the computer program is executed by the processor, it implements the fast recovery method for program faults of the relay protection system as described above.

[0012] To achieve the above objectives, the present invention also provides a computer-readable storage medium storing a computer program, which, when executed by a processor, implements the method for rapid recovery of program faults in a relay protection system as described above.

[0013] According to the present invention, the present invention is based on a multi-core heterogeneous system, allowing the monitoring system and the real-time system to run on independent CPU cores.

The mirror backup of this memory area can be used to restore the program to the initialization state and continue running. This can effectively avoid system restart and avoid re-initializing the hardware and software operation process. Therefore, it can realize the rapid recovery of the relay protection system and ensure that the power equipment is always in a protected state. Attached Figure Description
