Automatic test system for functions of television set and method thereof

Abstract

The invention discloses an automatic test system for the functions of a television set and a method thereof. The system comprises a computer system, a signal generator, a power tester and a television system; the computer system is connected with the signal generator, so that various signal formats and test maps required by a test are generated and output to the television system; the computer system is connected with the television system, so that the television system is notified to complete relevant operation and simultaneously read the state and data fed back by the television system; and the computer system is connected with the television system through the power tester, so that the power signals of the television system are acquired. According to the system and the method thereof, a computer serves as a central control unit, control software serves a core part for coordinating the work of all units, whether the image display and sound output are normal or not is judged by reading the power difference of the power tester, no external command input module and manual interference are needed, and an operator can automatically test all the functions of the television set only by pressing one button of the computer system.

Description

technical field [0001] The invention relates to the technical field of TV function test, in particular to an automatic test system and method for TV function. Background technique [0002] TV is a household appliance commonly used in people's daily life. With the continuous improvement of TV technology and the continuous upgrading of TV products, the functions of TV are increasing. After the TV is manufactured, it is usually necessary to modify the TV Do a functional test. figure 1 It is the system block diagram of the existing TV function test. The existing technology is actually based on the original TV software to increase the automatic test function. It needs an instruction input module (generally a remote control signal or a button signal) to start the TV automatically. With the automatic test action, at the same time, it needs to manually judge whether the displayed signal is normal or not. The test signal is automatically switched, but whether the function is normal...

AI Technical Summary

Problems solved by technology

The test signal is automatically switched, but whether the function is normal or not still needs to be manually judged, and the automatic test of the TV function cannot be completed automatically

[0003] Because existing TVs generally have many channels such as HDMI, Component, VGA, CVBS, RF, etc., under the existing technical conditions, manual judgment is required, which not only requires high technical level of inspection and judgment personnel, but also easily causes fatigue , omission, which will bring greater quality hidden dangers
