In addition, it is necessary to supplement that, in addition to the signal processing process provided in the embodiment of the present invention, the client upper computer may also send data (equivalent to an inspection mechanism) to the MPU by using a serial port protocol, for example, the client upper computer receives the data sent by the MPU, but the client upper computer now does not need to process the data, and sends an instruction to the MPU, and after receiving the instruction, the MPU re-screens some data and then sends the data to the client upper computer again for processing.
In another preferred embodiment, the SOA server module processes the received first vehicle signal to obtain a second vehicle signal, which specifically includes:

and the client upper computer compares the signal sending time, the signal name, the signal length and the data value corresponding to the first vehicle signal with the signal receiving time, the signal name, the signal length and the data value corresponding to the third vehicle signal in sequence to obtain a signal comparison result.

It should be noted that the time, the signal name, the signal length, and the data value corresponding to substantially the same vehicle signal compared by the client upper computer are sequentially compared, that is, the signal sending time corresponding to the first vehicle signal is compared with the signal receiving time corresponding to the third vehicle signal, the signal name corresponding to the first vehicle signal is compared with the signal name corresponding to the third vehicle signal, the signal length corresponding to the first vehicle signal is compared with the signal length corresponding to the third vehicle signal, and the data value corresponding to the first vehicle signal is compared with the data value corresponding to the third vehicle signal.
As an improvement of the above scheme, the client upper computer compares the signal sending time, the signal name, the signal length, and the data value corresponding to the first vehicle signal with the signal receiving time, the signal name, the signal length, and the data value corresponding to the third vehicle signal in sequence to obtain the signal comparison result, specifically:

for time comparison, a time difference value between signal sending time corresponding to a first vehicle signal and signal receiving time corresponding to a third vehicle signal is calculated and obtained (time difference value = signal receiving time-signal sending time), whether the time difference value does not exceed a preset time threshold value is judged (for example, whether the time difference value is within 1s is judged), when the time difference value does not exceed the preset time threshold value, a time comparison result is judged to be passed, and when the time difference value exceeds the preset time threshold value, the time comparison result is judged to be not passed;
aiming at name comparison, directly comparing a signal name corresponding to a first vehicle signal with a signal name corresponding to a third vehicle signal to judge whether the two signal names are the same, when the two signal names are the same, judging that a name comparison result is passed, and when the two signal names are different, judging that the name comparison result is not passed;
