Embodiment Construction

[0016] All features disclosed in this specification, or all disclosed steps in a method or process, may be combined in any way except mutually exclusive features and / or steps.

[0017] Combine below figure 1 , figure 2 The present invention will be described in detail.

[0018] like figure 1 Shown is a block diagram of the automatic power-off process of the intelligent automatic power-off socket. The intelligent automatic power-off socket includes a control circuit and a delay circuit. The infrared radiation signal of the human body detected by the infrared sensor in the control circuit is converted into an electrical signal, which is amplified by the primary and then amplified by the third-stage integrated operational amplifier. The control circuit is based on the three-stage integrated operational amplifier. The electrical signal after the stage integrated operational amplification controls the on-off of the relay in the delay circuit.

[0019] like figure 2 Shown is ...

Abstract

The invention discloses an intelligent automatic power-off socket which comprises a control circuit and a time-delay circuit. Electrical signals output from an infrared sensor in the control circuit are subjected to primary amplification and then subjected to three-level integrated operational amplification, and the control circuit controls on-off of a relay in the time-delay circuit according to the electrical signals subjected to the three-level integrated operational amplification. Due to the fact that the control circuit controls on-off of the relay and then controls on-off of a power source, the intelligent automatic power-off socket has the advantages of being sensitive, reliable and high in anti-interference performance; if the infrared sensor can not detect infrared radiation of a user body, the intelligent automatic power-off socket can carry out automatic power-off after the time-delay circuit delays for a while, and therefore the purposes of saving energy and preventing accidents like fire disasters can be achieved.

Description

technical field [0001] The invention relates to the technical field of connection devices, in particular to an intelligent automatic power-off socket. Background technique [0002] In today's society, electrical appliances have become a necessity in our daily life. Sometimes when people use some high-power electrical appliances, they forget to turn off the power of these high-power electrical appliances when they go out for various reasons, which not only wastes energy, but also may Accidents such as fires will occur, posing a serious threat to our personal and property safety. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide an intelligent automatic power-off socket for judging whether a user goes out to turn on and off the power according to the detection of the infrared radiation signal of the human body. [0004] The technical scheme adopted in the present invention is as follows: [0005] The invention provides an intelligent auto...
