Claims (10)
1. A protection method of an embedded operating system is characterized in that the protection method is applied to embedded equipment, the embedded equipment comprises a first control unit and a second control unit, the first control unit and the second control unit carry the same embedded operating system, and the protection method comprises the following steps:
when the abnormal operation state of the first control unit is detected, controlling the second control unit to operate to continuously execute the target operation task of the first control unit;
and when the operating state of the first control unit is detected to be recovered to be normal, controlling the first control unit to operate so as to continuously execute the target operating task.
2. The method as claimed in claim 1, wherein the embedded device further comprises a peripheral device, the first control unit is in signal connection with the peripheral device through a first control interface, the second control unit is in signal connection with the peripheral device through a second control interface, and the step of controlling the second control unit to operate to continue to execute the target operation task of the first control unit when the abnormal operation state of the first control unit is detected comprises:
and when the abnormal operation state of the first control unit is detected, controlling the second control unit to communicate with the peripheral device through the second control interface so as to enable the peripheral device to execute the target operation task of the first control unit.
3. The method according to claim 2, wherein the step of controlling the first control unit to operate to continue to execute the target operation task upon detecting that the operation state of the first control unit returns to normal comprises:
and when the operation of the first control unit is detected to be recovered to normal, controlling the first control unit to communicate with the peripheral device through the first control interface so as to enable the peripheral device to continuously execute the target operation task of the first control unit.
4. The method as claimed in claim 1, wherein the embedded device further comprises a storage unit, the storage unit is in signal connection with the first control unit and the second control unit respectively, and the step of controlling the second control unit to operate to continue to execute the target operation task of the first control unit when the abnormal operation state of the first control unit is detected comprises:
when the operating state of the first control unit is detected to be abnormal, controlling the second control unit to read task data of the target operating task from the storage unit;
and controlling the second control unit to execute the target running task of the first control unit through the task data.
5. The method of claim 1, wherein prior to the step of controlling the second control unit to operate to continue to perform the target operational task of the first control unit upon detection of an operational state anomaly of the first control unit, the method further comprises:
acquiring a heartbeat packet of the first control unit or a mark which is written by the first control unit and runs normally;
and if the heartbeat packet or the normal operation mark is found to be wrong, determining that the operation state of the first control unit is abnormal.
6. The method of claim 5, wherein the method further comprises:
and performing system recovery on the first control unit while controlling the second control unit to operate to execute the target operation task of the first control unit.
7. The method of claim 5, wherein the method further comprises:
controlling the second control unit to reset the first control unit;
and when the second control unit fails to reset the first control unit, marking the running state of the first control unit as abnormal.
8. An embedded operating system protection device, comprising:
the first control module is used for controlling the second control unit to operate to continuously execute the target operation task of the first control unit when the abnormal operation state of the first control unit is detected;
and the second control module is used for controlling the first control unit to operate to continuously execute the target operation task when the operating state of the first control unit is detected to be recovered to be normal.
9. An electronic device, comprising: memory, processor and computer program stored on the memory and executable on the processor, the processor implementing the steps in the embedded operating system protection method according to any one of claims 1 to 7 when executing the computer program.
10. A computer-readable storage medium, having stored thereon a computer program which, when executed by a processor, carries out the steps in the embedded operating system protection method according to any one of claims 1 to 7.
