Vehicle-mounted Android host test board based on visual feedback

Abstract

The invention belongs to the field of test equipment of vehicle-mounted sound equipment hosts, in particular relates to a vehicle-mounted Android host test board. The test board comprises a camera andimages shot according to the camera. A method comprises: extracting image features, comparing the image features with interface images stored in a computer to determine the current state of the host,and determining the target state to be reached by the tested host and the feature and skip state transition table of each interface according to the interface and the function which need to be openedby the test item to be carried out; controlling the three-axis mechanical arm arranged in the darkroom by the computer; clamping a touch control pen at the tail end of the computer to simulate an interface of a touch operation touch screen of a human finger, and triggering a jumping condition according to the characteristics of each interface set in the computer and a jumping state transition table, so that the tested host jumps to different interfaces or executes corresponding actions to generate state transition. The test board is not limited by test instructions any more. A host designer does not need to design a series of instructions specially used for testing any more, and the workload of the designer is reduced.

Description

technical field [0001] The invention belongs to the field of testing equipment for a vehicle-mounted audio host, and in particular relates to a test platform for a vehicle-mounted Android host. Background technique [0002] After the car audio head unit is assembled, a final test should be carried out to check whether the performance of the head unit is up to standard. The functions of the traditional vehicle-mounted head unit are mainly audio playback functions such as radio, CD music, and USB music. It is also a common operation during testing. Most of the existing test methods are to design test instructions to realize corresponding operations, and design corresponding interpreter and execution program in the tested host. For example, the Chinese invention patent with the notification number CN109213116A discloses "a centralized testing device and method for a vehicle infotainment system". Instructions are sent to the object under test and associated test instruments. ...

Problems solved by technology

[0004] In order to overcome the problems of high difficulty in test instruction design, heavy workload, and poor expansion ability in the prior art, the present invention provides a vehicle-mounted Android host test platform based on visual feedback, so that all operating functions that can be realized through buttons and touch screens are all available. No need to design test instructions, just enter the state transition table of the host computer under test in the test bench computer, the test program can automatically generate the action sequence of the three-axis robotic arm according to the test content, and use the camera to capture the program interface on the touch screen of the vehicle host, Through the program in the test bench PC, each control of the touch screen program interface is identified, and the three-axis mechanical arm is controlled to click the corresponding button control on the touch screen according to the generated action sequence, simulating human touch operation, and the relay and resistor network are used to form The button simulation circuit simulates the operation of pressing a mechanical button
