Problems solved by technology

[0002] With the development of electronic technology, computer technology and information technology, digital TV has become a commonly used TV system at present, and digital TV set-top boxes are widely used as terminal equipment of the entire digital video broadcasting system. For error-free, safe and reliable operation, the set-top box motherboard needs to undergo precise functional testing before assembly; the traditional set-top box motherboard test requires the operator to hold the remote control and press the corresponding button according to each function to be tested. For example, when testing a set-top box The operator presses the "radio" key of the remote control when the main board is broadcasting; when testing the channel function, the operator presses the corresponding number key to switch channels; when testing the navigation page function, the operator presses the "navigation" key of the remote control etc.; there are following shortcomings in the existing manual testing process: first, when completing each function test, the operator needs to frequently use the "OK" key "back" key to exchange, so that the whole testing process takes a long time and takes a long time. Second, because there are many models of set-top box motherboards, and there are differences in the testing procedures of various types of motherboards, it is easy for operators to miss some test items in different test processes, resulting in a difference in the factory pass rate of set-top box motherboards. Third, due to the low compatibility of existing remote controllers, it is necessary to use corresponding remote controllers for different types of set-top box motherboards during the test process, which greatly increases the cost of testing
Compared with traditional manual testing, a lot of research and improvement have been carried out in the prior art. For example, Chinese patent 201310412789 discloses a test method, device and system for a digital set-top box. By creating a communication between a simulated physical disk and a digital set-top box, a digital set-top box is realized. The test of the reading and writing function of the external physical disk; Chinese patent 201210086170 discloses a test method and test system for a set-top box, and performs corresponding functional tests by preset control commands on the PC; The method, which stores the remote control information of the set-top box to be tested in the test device in advance, and then sends the remote control information to other modules in the test device to realize the corresponding operation test; the various set-top box test methods and devices disclosed in the above-mentioned patent technology The steps are cumbersome and the device is complicated, so it is necessary to design a simple method for automatic testing of the set-top box motherboard, which does not require frequent operation of the remote control buttons, and is compatible with a variety of set-top box motherboard models, and realizes the set-top box motherboard by automatically sending key signals. Automatic testing of various functions
