Description

Technical Field

[0001] The present invention relates to the technical field of vehicle-machine connection function testing, and in particular to a vehicle-machine connection function wake-up verification test system and a test method based on a robotic arm. Background Art

[0002] With the popularization of intelligent automotive electronics, the development of car-to-mobile phone interconnection technology and its application in the field of smart cockpits are becoming more and more extensive. A large number of wireless sensor devices in the car coexist in the same space, which brings great interference and communication failure risks to wireless communication equipment. The interconnection function between the car and the mobile phone may be abnormal. Therefore, the car-to-mobile phone connection function wake-up test needs to be performed on the car.

[0003] Since the test results of the current car computer are evaluated and presented in a qualitative way rather than quantitatively, and some laboratories do not have the conditions for testing the multivariable control system of the car computer connection function, it is not enough to support accurate quantitative testing. Therefore, the existing test methods for the connection function of car computer products generally use a test method that manually clicks on the car computer to operate and judges the results through manual witnessing.

[0004] However, the above purely manual testing method has the following defects: during the test process, there will be random deviations in the position of each manual click on the car computer screen interface, which cannot be verified repeatedly. The linear single test cannot fully simulate the actual working environment of the tested car computer. Summary of the invention

[0005] The first object of the present invention is to provide a vehicle-machine connection function wake-up verification test system based on a robotic arm.

[0006] The second object of the present invention is to provide a testing method for the vehicle-machine connection function wake-up verification test system based on a robotic arm.

[0007] The present invention can save manpower, improve the accuracy of the test, and record the test process.

[0008] The first object of the present invention is achieved by the following technical solutions:

[0009] A vehicle-machine connection function wake-up verification test system based on a robotic arm is characterized in that it includes a power supply, a monitoring device, a sample fixture, a robotic arm, a computer and a mobile phone used to cooperate with a vehicle-machine under test for wireless connection. The power supply supplies power to the monitoring device, the sample fixture, the robotic arm, the computer and the mobile phone. The touch pen is fixedly installed on the movable end of the robotic arm and is used to click the corresponding position of the screen of the vehicle-machine under test. The sample fixture is used to clamp the vehicle-machine under test. The camera of the monitoring device is used to record the interface of the screen of the vehicle-machine under test and the interface of the mobile phone screen. The computer is electrically connected to the monitoring device, the robotic arm and the mobile phone. The computer can control the robotic arm and obtain the video recorded by the monitoring device and the work log of the robotic arm.

[0010] A further technical solution of the present invention is: it also includes a test bench, and a power supply, a monitoring device, a sample fixture, a mechanical arm, a computer and a mobile phone are all arranged on the test bench.

[0011] A further technical solution of the present invention is: a mounting frame is also provided on the test bench, and a camera of the monitoring device is installed on the mounting frame.

[0012] The second object of the present invention is achieved by the following technical solutions:

[0013] A test method of a vehicle-machine connection function wake-up verification test system based on a mechanical arm is characterized by comprising the following steps:

[0014] S1, clamp the vehicle under test on the sample fixture, mark the position where the connection function is clicked on the screen of the vehicle under test as the first point, and mark the position where the disconnection function is clicked on the screen of the vehicle under test as the second point;

[0015] S2, turn on the wireless connection function of the mobile phone and make sure the mobile phone is not connected to the vehicle under test;

[0016] S3, moving the touch pen on the robotic arm to a first point, recording the coordinate value of the robotic arm at this time as the coordinate of the first point, and then moving the touch pen on the robotic arm to a second point, recording the coordinate value of the robotic arm at this time as the coordinate of the second point;

[0017] S4, turning on the monitoring device, and using the camera of the monitoring device to record the interface of the screen of the vehicle under test and the interface of the mobile phone screen;

[0018] S5, controlling the robot arm to click alternately between the first point coordinate and the second point coordinate, and stop after clicking a set number of times;

[0019] S6, the computer obtains the video recorded by the monitoring device and obtains the work log of the robotic arm;

[0020] S7, change to another model of mobile phone and repeat the above steps S2 to S6.

[0021] A further technical solution of the present invention is: in step S3, after the first point coordinates and the second point coordinates are entered into the computer, the first point coordinates and the second point coordinates need to be calibrated. After the calibration is completed, the number of times the robot arm repeatedly clicks the first point and the second point alternately is set.

[0022] A further technical solution of the present invention is: in step S5, when a corresponding prompt box indicating successful connection pops up on the mobile phone screen, it means that the mobile phone is successfully connected to the vehicle under test.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. The present invention uses a mechanical arm to repeatedly operate the connection function of the vehicle computer under test, and the click positions can be recorded and reproduced, thereby solving the problem of misoperation due to repetitive actions during manual testing, and solving the problem that when the vehicle computer connection function fails to wake up during manual testing, it is impossible to locate the time point when the failure occurs, thereby reproducing the abnormal state of the vehicle computer under test and finding out the potential risks of the vehicle computer under test.

[0025] 2. The present invention can achieve precise clicking by setting coordinate points to control the clicking of the robotic arm, thereby solving the problem that the function buttons cannot be accurately located on the screen of the vehicle under test during the test, ensuring the true acquisition of the wake-up function of the vehicle under test, and making the test process of the vehicle under test more in line with the actual application scenario.

[0026] 3. The present invention records through a monitoring device, and obtains the video recorded by the monitoring device and the work log of the robotic arm through a computer, thereby realizing automatic collection and recording of the test process, simplifying the data recording and equipment operation process, so that the entire test system can automatically complete the test and record the original data after calibration and debugging without the need for special personnel on duty.
