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

Embodiment Construction
[0051] figure 1 It is a logical structure diagram of the first embodiment of the power-taking circuit of the smart device of the present invention. Firstly, it is explained that the smart device is, for example, a smart TV, a smart indoor intercom extension device, a smart Robotic devices, smart gateways, smart routers and other equipment, smart devices include processors, sensing modules, audio / video acquisition modules, communication modules and other energy-consuming modules. Therefore, the operation of smart devices requires reliable power supply.
[0052] In this embodiment, the power taking circuit of the smart device can take power from the first live line of the AC circuit where the first load is located, for example, the first load is installed in the living room / bedroom / dining room / kitchen / toilet / meeting room / exhibition hall / Lamps, fans and other devices in hotels. Moreover, the power-taking circuit is connected to the processor of the smart device, and can receiv...

The invention relates to an intelligent device and its power-taking circuit and method. The power-taking method includes: judging whether the user has a demand for turning on the first load; It is connected to the first output end; when it is determined that the user has no need to turn on the first load, the input end of the control switch is connected to the second output end, and it is judged that the first condition or the second condition is currently satisfied; When the second condition is satisfied, the intelligent switch is controlled to be turned off; when it is determined that the second condition is satisfied, the intelligent switch is controlled to be turned on. The implementation of the technical solution of the present invention mainly solves the problem of smart devices taking power from any indoor strong current circuit without wiring. When taking power from a single live wire, it is determined that the user is within a specific location at night and the power of the energy storage unit is not lower than the preset value. When the power is taken from the smart device, the power supply to the smart device is stopped, which can prevent the user from feeling uncomfortable due to the weak current flowing through the first load.
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.
