s101: and performing cyclic redundancy check on the local safety related data and/or the input/output data, generating a first check value and sending the first check value to the backup central processing unit.
It should be noted that the present application is applied to two-in-two systems, and for any CPU in two-in-two systems, the CPU that performs data interaction with the CPU is the backup CPU. The cyclic redundancy check is CRC (Cyclic Redundancy Check) check.
S102: and receiving a second check value which is sent by the backup central processing unit and is used for carrying out cyclic redundancy Yu Jiaoyan on the local safety related data and/or the input and output data, and comparing the first check value with the second check value.
That is, when the application performs the binary check, the original data is not required to be transmitted between two CPUs, and only the check value of CRC check performed on the local CPU is required to be transmitted and compared, so that the data transmission quantity between the two CPUs is effectively reduced, the running efficiency of the CPUs is improved, the check duration is reduced, and the check efficiency is improved under the condition of ensuring the binary check. And CRC protection is adopted for the local safety related data and/or the input and output data, so that the data safety is improved.

That is, when the storage amount of the check value of the backup CPU reaches a preset value or the backup CPU obtains a first control instruction for outputting data to the external device, the backup CPU sends a second check value to the local CPU, the local CPU receives the second check value sent by the backup CPU and judges whether the first check value is consistent with the second check value, if the first check value is consistent with the second check value, a first confirmation signal is generated and sent to the backup CPU, so that the backup CPU can output data to the external device according to the second confirmation signal and the first confirmation signal which are checked by the backup CPU, and receives the second confirmation signal sent by the backup CPU, and output data to the external device according to the first confirmation signal and the second confirmation signal, so that the local CPU and the backup CPU can alarm and stop data processing if the first check value is inconsistent with the second check value.
According to another embodiment of the present application, before performing the cyclic redundancy check on the local security related data and/or the input/output data, the method may further include: a first control instruction is obtained to output data to the external device.
That is, the local CPU may start performing the cyclic redundancy check on the local security-related data and/or the input-output data after receiving the first control instruction to output the data to the external device.
