Embodiment Construction

[0028] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0029] figure 1 It is a television environment stress testing device of an embodiment. The television environment stress testing device 10 includes a main controller 100 , a relay circuit 200 and a converter circuit 300 . The converter circuit 300 is used to convert the detected temperature into a thermal electromotive force signal and output it. The thermocouple of the converter circuit 300 is placed in the test chamber 40 . The main controller 100 is conn...

Abstract

The invention relates to a television environment pressure testing device, comprising: a converter circuit for converting a detected temperature into a thermoelectromotive force signal and outputtingthe signal; a main controller connected with the converter circuit, the controller being configured to receive the thermoelectromotive force signal and output an on-off signal; and a relay circuit connected with the main controller and configured to receive the on-off signal and perform isolation control over the main controller and a power supply path according to the on-off signal, wherein the power path is established by an external power supply and a load. The invention also relates to a television environment pressure testing method based on the television environment pressure testing device. Thus, the consistency between the power supply and the test chamber temperature is achieved, the problem of insufficient power supply when testing a plurality of televisions at the same time is overcome, the testing efficiency is further improved and the testing cost is reduced.

Description

technical field [0001] The invention relates to the technical field of television testing, in particular to a television environment pressure testing device and method. Background technique [0002] At present, all TV manufacturers will conduct a series of tests on the TV before leaving the factory to ensure that the quality meets the standard. Among them, the environmental stress test of the TV is a very important item, because it directly affects the use of the TV in the future. service life in different environments. [0003] At present, the traditional TV environmental stress test generally uses a programmable AC power supply to control the TV to perform tests according to the preset power supply state curve and the state curve of the environmental test chamber. However, due to the high cost of the programmable AC power supply, and for testing many TVs at the same time, its driving force will be obviously insufficient; and there is no feedback system between the program...
