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.
