Power supply control system and power supply control method

Abstract

According to the power supply control system provided by the invention, an internal electronic switch is switched off to control a zero line time-sharing generator to be directly switched on, and a zero line is switched on to a zero line end of an intelligent switch through the zero line time-sharing generator so as to supply power to a zero line and a live line of the intelligent switch; the internal electronic switch controls the live wire time-sharing conduction device to be conducted in a closed-loop mode so as to supply power to load equipment in a time-sharing mode, and the zero line time-sharing generator can be automatically cut off when detecting that the live wire time-sharing conduction device is conducted according to the set corresponding time of one-time or multi-time cut-off at the zero crossing point of the sine wave of the alternating current. And when the null line time-sharing generator detects that the live wire time-sharing conduction device is cut off, the null line is automatically conducted to supply power to the intelligent switch in a time-sharing manner, so that null and live wire power supply of the intelligent switch is realized. The invention provides a power supply control method. According to the technical scheme, zero and live wire power supply of the intelligent switch is achieved under the condition that the switch bottom box is not provided with a zero wire, installation is easy, and the application range is wide.

Description

technical field [0001] The invention relates to the technical field of intelligent switches, in particular to a power supply control system and a power supply control method. Background technique [0002] At present, with the development of science and technology, the Internet of Things technology is becoming more and more popular. Smart switches are a representative product of the Internet of Things. Simply replace the currently used wall switches, especially the standard wall switches, and simply replace the old mechanical switches in the home with smart switches to endow the corresponding electrical equipment with computing, memory and networking functions. Coupled with the widespread popularity of smart devices, especially smart phones, it has become easy to control electrical appliances at home with mobile phones. And can be very convenient to realize intelligent control. For example, when watching TV, use the mobile phone to remotely turn on the room lights, remotel...

Problems solved by technology

However, for the vast majority of households whose switches are buried in the wall for aesthetics, adding this zero line can be said to be difficult and costly. It is necessary to hire wall chiselers, electricians, wall repairers, and decoration masters.

The lack of this zero line has become a roadblock for smart switches to enter thousands of households
