Intelligent switch based on infrared body temperature measurement technology

Abstract

The invention relates to an intelligent switch based on infrared body temperature measurement technology and belongs to the field of automatic control. The intelligent switch comprises a signal acquisition circuit, an analog-to-digital conversion circuit, a single-chip microcomputer control circuit, a clock circuit, an infrared remote control circuit and the like. The intelligent switch is capable of starting a specified electric appliance by sensing body temperature to detect the value of post-sleeping body temperature change in human body at night, thereby automatically turning on or off the electric appliance. The intelligent switch can be set with time and mode of starting operating by a user. Compared with the prior art, the intelligent switch allows for automatic powering on and off according to the body temperature change of a user, thereby saving electricity, prolonging lifetimes of electric appliances and preventing safety hazards. The intelligent switch is applicable to indoor space of families and is high in practicality and reliability, simple to operate, and low in price.

Description

technical field [0001] The invention relates to an intelligent switch based on infrared human body temperature measurement technology, which is characterized in that it can detect the body temperature of the human body, realize the automatic start-up control of electrical appliances, and can detect the value of the body temperature change after the human body falls asleep at night, so as to automatically realize the control of electric lights and other electrical appliances. The shutdown control of the smart switch, and the user can set the time and mode for the smart switch to enter the working state, which belongs to the automatic control device. Background technique [0002] At present, saving electricity is the theme of social life, so it is necessary to continuously improve the technical level of electric energy utilization. Saving electricity can not only practice the concept of low-carbon and environmentally friendly life and reduce expenses, but more importantly, it ...

Problems solved by technology

[0003] At present, there are many types of home smart switches on the market, and there are hundreds of them. The technologies used are nothing more than the following four: one is power carrier control, although the price is cheap, it uses power lines to transmit signals. It will be interfered by power line clutter, which will make the work very unstable and lead to loss of control; the other is wireless radio frequency control. Although the cost is relatively low, it uses radio frequency to transmit signals. The switch is often interfered by radio waves, making its frequency not Stable; the third is the bus control type, although the stability and anti-interference ability is relatively strong, but its system security is relatively poor, the central controller is paralyzed, which will affect the operation of the entire system; there is also a single live wire control type, although the wiring method Same as the traditional switch, easy to install, but it cannot realize network control switch operation

The above smart switch modes have their own advantages and disadvantages, and play different roles according to different usage occasions. However, the after-sales service of the above smart switches is very troublesome and requires professionals to install them.
