Method for automatically controlling household appliance to be switched off

Abstract

The invention belongs to the technical field of electrical control, and relates to a method for automatically controlling a household appliance to be switched off. Firstly, a pulse type pressure-sensitive sensor is arranged at a pulse beating conventional testing position of a household appliance user before the user sleeps, then pulse beating number M per minute of the household appliance user in a sleeping state is set through a control button keyboard and the value M is stored, the pulse beating number N of the household appliance user is automatically measured and judged according to a preset measuring time sequence, when N is not larger than M, a control circuit in the pulse type pressure-sensitive sensor generates trigger signals, amplifies the trigger signals and then forms switch-off driving electric signals capable of driving a relay, and a pulse type switch-off control device controls the relay arranged at the input port of the household appliance to automatically cut off the power supply of the household appliance under the driving action of the switch-off driving electric signals. The method for automatically controlling the household appliance to be switched off is simple in design principle, mature in technology, reliable in control principle, flexible and convenient to use, accurate in counting, and high in control automation degree, saves energy, enhances benefits, and is beneficial to the environment.

Description

Technical field: [0001] The invention belongs to the field of electrical control technology, and relates to a technology for controlling the power cutoff of household appliances, especially mobile phones and earphones, video and audio household appliances, according to the electrical information of the pulse beating state of the human body, especially a technology for automatically controlling the power-off of household appliances method. Background technique: [0002] At present, all kinds of household appliances have generally become the most common audio-visual tools and equipment in homes and public places, especially audio-visual household appliances, such as radios, televisions and mobile phones, are almost inseparable from people's daily life. When appreciating and using these electrical appliances, it is often necessary to control the working time or closing time of these electrical appliances through manual switches, remote controllers or other automatic control dev...

Problems solved by technology

There is often a common phenomenon in the use of household appliances, that is, after the users of the appliances slowly fall asleep, these appliances may continue to work. For example, many people turn on the radio, MP audio headphones, mobile phones before going to sleep Watching programs or listening to audio with TV, etc., when the user falls asleep, the electrical appliance is still on, which not only wastes electric energy, but also increases the use time of the electrical appliance and reduces the life; many electrical applianc...
