Intelligent home positioning method

The invention relates to a method for positioning a smart home, which is a kind of practical invention which is a kind of practical application for accurately detecting the position of a person in the home room through a heat source emitted by the human body.

With the advancement of technology, people's level of living at home has gradually improved. When people come home early in the early hours of work, they want to take a rest, bathe, watch TV, and air-conditioner to enjoy life after work, but It takes a little time to turn these home appliances on and wait for the mechanical heat engine to be used. This will not only completely relax, but also lead to further fatigue.

To this end, the advancement of science and technology has brought people a more convenient life. Today's technology allows people to set time for home appliances in advance when they are in the field. When people return home when they set the time, they set the home appliances. It can be operated immediately, so as to prevent the user from dragging the tired body to open various household appliances. In addition, the home appliance can be remotely controlled by wireless remote control. When people are on their way home, they can use it first. The mobile phone type controller wireless remote control home electrical appliances will be put into operation, so that the electrical appliances in the home will operate first, so that people can enjoy the comfort brought by household appliances when they return home, in addition to controlling the startup of home appliances, It can further protect the security of home life by setting up a home security system and monitoring system.
