Since the display signal can be stripped of multiple key frame signals, each key frame signal has its own corresponding timestamp.
Specifically, under the condition that the type of the test case is a performance test case, the server de-frames the received display signal to obtain a key frame signal, and further determines the test result of the intelligent cabin according to the key frame signal and the time stamp of the key frame signal.
In a specific embodiment, the server is further configured to: determining a first test result based on the key frame signal and a first preset image signal; determining a second test result based on the timestamp of the key frame signal and a preset time threshold; and determining a cabin test result based on the first test result and the second test result.
Specifically, the key frame signal is compared with the first preset image signal, if the matching of the key frame signal and the pixels of the first preset image signal is consistent, the first test result is successful, otherwise, the first test result is failed.
The time stamp of each key frame signal minus the time stamp of the start frame signal of the display signal is the execution duration of the key frame.

The second type refers to a functional test case for performing functional tests on the intelligent cabin.
The display signal includes a multi-frame signal in which a more critical frame signal among the multi-frames is a key frame signal, for example, for a display signal of an open map, a signal of a first frame (a map has not been opened yet) and a signal of a last frame (a fully open map) belong to the key frame signal.
The preset time period may be a preset time value, for example, 1s, 2s, 3s, 3.5s, etc. may be taken as examples of the preset time period.

Specifically, the key frame signal is compared with the second preset image signal, if the matching of the key frame signal and the pixels of the second preset image signal is consistent, the third test result is successful, otherwise, the third test result is failed.
And comparing the display image with the third preset image, if the pixel matching of the display image and the third preset image is consistent, the fourth test result is successful, otherwise, the fourth test result is failed.
In one embodiment, each key frame signal in the display signal need not be compared, so long as the key frame signals that are forward in time series are compared.
Only if the third test result and the fourth test result are both passed, the test result of the test case is passed, and if one of the test result and the test result is failed, the test result of the test case is failed.
In addition, the types of the test cases can be other types, and particularly, the standby expansion can be carried out by a tester so as to realize the test of other relevant vehicle-mounted performances of the intelligent cabin.
In a specific embodiment, the server is further configured to send the standard time to the industrial personal computer; the industrial personal computer is also used for synchronizing the system time of the industrial personal computer and the vehicle by adopting an NTP (network time protocol) based on the standard time.
Specifically, the industrial personal computer and the cabin domain controller are both provided with NTP programs, and the server is responsible for sending the standard time to the industrial personal computer, and the system time of the industrial personal computer is synchronized with the system time of the vehicle through the NTP protocol.

The vehicular terminal special distributed test execution program is deployed on the MINI industrial personal computer, and the program can provide the functions of test execution, test environment self-checking, data acquisition, data uploading and the like. And registering the vehicle-mounted MINI industrial personal computer in the cloud server, and verifying the operation environment.
FIG. 3 is a complete flow diagram of a vehicle cabin testing method in one embodiment of the present application.
Specifically, as shown in fig. 3, the cloud server detects whether the MINI industrial personal computer is online, and if the MINI industrial personal computer is not online, the cloud server continuously detects the MINI industrial personal computer at a preset frequency (for example, every ten minutes Zhong Yici).
When the MINI industrial personal computer is detected to be online, the cloud end can issue test cases and test task starting time to the MINI industrial personal computer.
And after the MINI industrial personal computer receives the test cases, detecting whether the test cases are received or not every minute until the test cases are received.
The MINI industrial control machine detects whether the task starting time is reached, and when the task starting time is reached, NTP programs deployed on the MINI industrial control machine and the intelligent vehicle-mounted cabin domain controller are started first so as to synchronize the system time of the MINI industrial control machine and the intelligent vehicle-mounted cabin domain controller.
And the MINI industrial personal computer is used for executing the preconditions of the cases, then starting to execute the test cases, recording the time stamp of the execution of the test cases when the case steps are executed, generating test instructions according to the test cases and sending the test instructions to the cabin domain controller.
The cabin domain controller controls the vehicle to execute corresponding actions according to the test instruction, and meanwhile generates a display signal and outputs the display signal to the signal separator. For example, for a test instruction to adjust a seat, the cabin controller adjusts the seat of the vehicle according to the instruction while generating a display signal that can be displayed on a display screen, which may be a set of multiple signals that can present the entire process of adjusting the seat on the display screen.
The differential signal separator separates the display signal output by the vehicle-mounted cabin domain controller into two paths, one path of display signal is output to the display screen, the other path of display signal is output to the industrial personal computer, and the display signal is uploaded to the cloud server in real time by the industrial personal computer.
When the cloud server receives the display signals uploaded by the industrial personal computer, the display signals are disassembled frame by frame to obtain key frame signals, and a test result is determined according to the key frame signals.
The MINI industrial personal computer is used for running a program, analyzing the test cases according to the case format, packing and storing display signals once every 30s when the test cases with the case type of performance (performance) are detected, using the current timestamp to be named as record_timexx.mp4, and recording the trigger time t_start corresponding to the case steps. After each single use case is executed, all the generated data are uploaded to the cloud.
The cloud end removes frames from the record_timexx.mp4, sorts frame time, and obtains a timestamp of the first frame. And comparing each key frame with a preset image, and if the two pixels are consistent, the first test result is successful. For the first key frame, the time t_end of the key frame is obtained by record_timexx.mp4, so as to obtain the execution duration t=t_end-t_star of the first key frame. And storing the test number and the execution duration to the cloud server, comparing the execution duration with an expected time threshold stored in the cloud server, and marking the second test result as successful when the execution duration is smaller than the expected time threshold stored in the cloud server, otherwise, marking the second test result as failed.
When the type of the case is detected to be a functional (function) test case, each key frame is also compared with a preset image, the pixels of the key frame and the preset image are consistent, and a third test result is successful. In addition, because of the non-performance test, only the final result after the preset time (for example, 2 s) is concerned, after the execution of the use case step is finished for 2s, the screen displays a stable image, the display image is grabbed, the display image is compared with the preset image, if the pixels of the two images are consistent, the fourth test result is successful, otherwise, the fourth test result is failed.
And after the cloud server receives the test result, storing the corresponding test result according to the test number.
And outputting a test report after all the test cases are executed.
Referring to fig. 4, fig. 4 is a schematic flow chart of main steps of a testing method of a vehicle cabin testing system according to an embodiment of the present application.

Step S100: the server sends the test case to the industrial personal computer.
Step S200: and executing the test case by the industrial personal computer, and sending a test instruction to the cabin controller based on the test case.
Step S300: and generating a display signal by the cabin domain controller according to the test instruction.
Step S400: the signal separator separates the display signal into two paths, and one path of display signal is sent to the industrial personal computer.
Step S500: the cockpit test results are determined by the server based on the display signals.
Based on the steps S100-S500, the vehicle-mounted test before the delivery of the vehicle is realized, and the test result of the intelligent cabin is determined by the server based on the display signals collected by the signal separator, so that the test efficiency and accuracy of the cabin are improved.
The specific implementation manner of the test method of the vehicle cabin test system is the same as that of the vehicle cabin test system in the foregoing embodiment, and is not repeated here.
