Wireless control terminal compatible with traditional electrical switch installation conditions

Abstract

The invention relates to a wireless control terminal compatible with traditional electrical switch installation conditions. The wireless control terminal comprises a control module, a wireless communication module, a power induction module, a power conversion module, storage modules and the like. When current passes through an AC power supply line which passes through a switch installation box, the power induction module takes electricity from the power supply line through electromagnetic induction; and a power harvesting circuit including but not limited to synchronous voltage-doubling rectification and DC-DC conversion is adopted by the power conversion module to generate DC supply and one or more paths of DC generated in the way are stored into one or more storage modules for supplying the other modules of the terminal with the electricity.

Description

technical field [0001] The invention relates to intelligent building accessories, in particular to a wireless control terminal compatible with the installation conditions of traditional electrical switches. Background technique [0002] In recent years, wireless network and wireless control technology, Internet of Things technology, and smart home have made great progress, and wireless network-controlled LED lamps and other electrical appliances are increasing. This also brings a challenge to the building decoration where and how to install the network control terminal, [0003] The ideal place to install the network control terminal is an existing switch box. As long as its cover plate does not shield the wireless signal, the wireless network can work normally. However, the power supply of the control terminal is a challenging issue. Usually there is only one of the AC circuits in the switch box, and it cannot be connected to the usual power adapter for power supply....

AI Technical Summary

Problems solved by technology

These have certain limitations, and their outstanding weakness is that the source of energy is difficult to guarantee

For example, the power supply of switching mechanical energy depends entirely on the number of switching times, and basically can only be used for switching terminals; solar energy is limited by lighting conditions, etc.,

[0005] In the application of test instruments, it is a common method to measure the current through the magnetic field around the current. It is theoretically feasible to obtain electric energy by means of magnetic field induction, but there are considerable challenges in engineering implementation.
