Detection system and method applicable to AC startup and shutdown test of television

Abstract

The invention relates to the technology for detecting the reliability of televisions, discloses detecting system and method applicable to the AC startup and shutdown of the television, and aims at solving the problems the television AC startup and shutdown test manner of the traditional technology needs testers to participate in all testing processes, which causes large workload and easily leads to omission. The method comprises the following steps: controlling the connection of an AC power supply of the television through a PC; sequentially communicating with an oscilloscope, an inter-machine debugging tool and a colorimeter; collecting the working data of a power supply, an inter-machine and a screen system; analyzing and determining; determining whether to suspend or continue the testing process according to the determining result; in case of no abnormality after determining, disconnecting the AC power supply of the television under the control of the PC; entering the next startup and shutdown cycle according to the preset parameters. According to the method, all the processes are completely automatic and can be done with one key; a problem point causing the fault can be accurately positioned; the system and method apply to the test of the television before delivery.

Description

technical field [0001] The invention relates to a reliability detection technology for a TV set, in particular to a detection system and method applied to a TV AC switch test. Background technique [0002] In the design, development and testing process of TV sets, in order to check the reliability of TV sets, it is necessary to frequently test the AC switch. At present, there is a special AC switch test instrument that can be used for testing, but this instrument is limited to on-off switching of the AC input voltage of the TV, and requires testers to be on duty to observe the test process and record test data at any time, especially when When an abnormal situation occurs, the test must be suspended immediately to keep the site. [0003] Since the testers must participate in the whole process, the workload is quite heavy, and it is very easy to overlook some occasional abnormalities, and it is also difficult to judge which part of the circuit system of the TV is responsible...
