Intelligent device and power taking circuit and method thereof

Abstract

The invention relates to an intelligent device and a power taking circuit and method thereof. The power taking method comprises the steps of: judging whether a user has the requirement for starting afirst load or not; controlling the input end of a change-over switch to be connected with a first output end of the change-over switch when it is determined that the first load needs to be started; controlling the input end of the change-over switch to be connected with a second output end of the change-over switch when it is determined that the user does not start the first load, and judging whether a first condition or a second condition is met currently; when it is determined that the first condition is met currently, controlling an intelligent switch to be turned off; and when it is determined that the second condition is met currently, controlling the intelligent switch to be switched on. The technical scheme of the invention is implemented, the method mainly solves the problem that the intelligent device does not have wiring power taking from any indoor strong current loop, when power taking is carried out through a single battle line mode, the conditions that a user is in a specific position range at night and the electric quantity of an energy storage unit is not lower than a preset value are determined, power taking of the intelligent device is stopped, and therefore the phenomenon that a first load causes discomfort to the user due to weak current flowing through the first load can be avoided.

Description

technical field [0001] The invention relates to the field of smart home, in particular to a smart device and its power-taking circuit and method. Background technique [0002] With the rapid development of information technology and network technology and the change and improvement of people's living concept, home intelligence has gradually become a hot topic, and the smart home industry is also known as a sunrise industry in the future. Smart home system refers to the use of integrated wiring technology, network communication technology, security technology, automatic control technology, audio and video technology to integrate home life-related facilities, build an efficient management system for residential facilities and family schedules, and improve home security. , convenience, comfort, artistry, and to achieve an environmentally friendly and energy-saving living environment. The smart devices in the smart home system (such as smart TVs, smart indoor intercom extension...

Problems solved by technology

Although this height is just suitable for the installation of some smart devices, because the switch wiring generally adopts a single live wire circuit (circuit connected in series with the lamp), and the smart device needs zero and live wire circuits (that is, no-load circuits) for power supply so as not to affect other loop

If the smart device is connected to the load circuit and takes power from the live line of the load circuit, when the load is turned on, the smart device can be powered, but when the load is turned off, there must be a small current in the load circuit to maintain the smart device. For some current-sensitive loads, such as low-power LED lamps or energy-saving lamps, since there is still a small current in the load circuit after the lights are turned off, in some environments (such as at night), the user may obviously feel The light will be slightly bright or flickering, so it will cause discomfort to the user and the user experience will be poor
