Gated power-off device

Abstract

Provided is a gated power-off device. The gated power-off device comprises a transmitting box and a receiving box, wherein an infrared transmitting tube is mounted in the transmitting box; an infraredreceiving tube is arranged in the receiving box; an infrared transmitting tube and an infrared receiving tube of the infrared geminate transistor are respectively installed on an indoor door body anda wall body; the infrared transmitting tube and the infrared receiving tube in the infrared geminate transistor are aligned when the door is closed; a relay switch is closed; the mains supply connected with the relay switch is disconnected; an indoor electric appliance power supply is turned off; and door closing outage and door opening electrification are achieved, and fire disasters caused by forgetting to turn off electricity indoors are reduced. According to the gated power-off device, power-off when people walk and power-on when people come are converted into power-off when the door is closed and power-on when the door is opened, and tedious detection on activities of people is not needed, so that the operability of judgment is improved.

Description

technical field [0001] The invention relates to a power cut control device, in particular to a power cut control device capable of controlling the power supply in a room through the switch of the house door. Background technique [0002] In the office or at home, people often forget to turn off the indoor oven, causing a fire. In order to reduce fire accidents, people want to design a kind of people walk power-off device always. Someone installs a pyroelectric infrared sensor for human body induction indoors, and judges whether there are people in the room through the induction of the infrared sensor; if there is no one, the controller sends a power-off command. However, this kind of pyroelectric infrared sensor is not sensitive to stationary people. At the same time, if the distance is far away or covered, it cannot sense whether there are people in the room. These judgments will cause many misjudgments. The authorized announcement number is CN101304248B, and the inventio...

Problems solved by technology

But in practice, the direction of people's actions is random. Faced with the entry and exit of many people and the stagnation at the door, this solution cannot accurately judge whether there are people in the room.
