Embodiment Construction

[0025] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0026] figure 1 It is a television switch testing device of an embodiment. The television switch testing device 10 includes a main controller 100 and a relay circuit 200 . The main controller 100 is used to execute a test program, and output a power-on / off signal according to the test program. The relay circuit 200 is connected with the main controller 100, receives the on-off signal, and controls the contact switch of the included relay to change the contact state according to the on-off signal. Wherein, the contact switch of the relay is used to be connected in the power path of the external p...

Abstract

The invention relates to a television switch testing device. The television switch testing device includes a master control device and a relay circuit, wherein the master control device is used for executing a test program, and outputting an on-off electric signal according to the test program; the relay circuit is connected with the master control device to receive the on-off electric signal, and controls the contact switch of the contained relay to change the touch state according to the on-off electric signal; the contact switch of the relay is connected between an external power supply and a power supply of a television; the master control device can have an accurate clock, and can perform accurate time control in the test program according to the clock of the master control device; when the relay circuit is delayed, time correction can be controlled by modification of the program, so that the television switch testing device can realize accurate time control; and as the relay circuit is not a semiconductor device and is not limited by the power factor, the relay circuit can start the television through a greater current so as to reduce starting delay of the television and achieve the aim of quick testing.

Description

technical field [0001] The invention relates to the technical field of television testing, in particular to a television switch testing device. Background technique [0002] Before the TV leaves the factory, it must pass various tests to ensure the quality is qualified. Among them, the switch test of the TV is a more important test. The switch test of the TV is mainly to keep the TV on and off and to test the remote control switch after power on. [0003] For the power on and off control of the TV set, a programmable AC power supply is traditionally used to control whether the power supply of the TV set is turned on or not, so as to realize the power on and off control. However, the time control precision of most programmable AC power supplies is not too high, and cannot achieve precision control within 1ms. When a programmable AC power supply is used, due to the limited power of semiconductor devices, the voltage drop phenomenon will occur when starting a large load, whi...
