Abstract

The invention discloses a TV automatic shutdown device, consisting of a case body, a passive infrared detector, a delay circuit and a switch control module. The passive infrared detector consists of a pyroelectric infrared sensor, a Fresnel lens, an amplification circuit and an output circuit. The Fresnel lens is arranged in front of the pyroelectric infrared sensor which is connected with the amplification circuit. The amplification circuit is connected with a micro-computer processor. electric signals transformed through the pyroelectric infrared sensor and signals amplified and transformed through the amplification circuit are electrically connected with the micro-computer processor. The micro-computer processor is connected with the delay circuit which is electrically connected with the switch control module. The passive infrared detector is arranged in the case body and is installed on the top cover of the TV set. The TV automatic shutdown device designed through the technical proposal has the advantage of intellectually recognizing that whether people watch TV or fall asleep and turning off TV power to save power when people who watch TV fall asleep.

Description

technical field [0001] The invention relates to a television shutdown system, in particular to an automatic television shutdown system. Background technique [0002] Work and study are very tiring all day. When I go home to watch TV at night, I often fall asleep while watching it, but the TV is always on and no one is watching. This wastes power and affects other people’s sleep. None of the existing technologies can solve this problem. Contents of the invention [0003] The purpose of the present invention is to provide an automatic shutdown system for a TV set; it can solve the problem of automatically turning off the power supply of the TV set when people fall asleep watching TV. [0004] The purpose of the invention of the present invention can be achieved through the following technical solutions. [0005] An automatic shutdown system for a television, comprising a box body, a passive infrared detector, a delay circuit and a switch control module, the passive infrare...
