Lithium battery based single firing line power-taking apparatus

Abstract

The invention provides a lithium battery based single firing line power-taking apparatus. The power-taking apparatus comprises a load and an intelligent switch; the intelligent switch comprises a static power-taking circuit, a relay, a lithium battery and a control unit; one end of the load is connected with the firing line while the other end of the load is connected with the input end of the static power-taking circuit; the output end of the static power-taking circuit is connected with one input end of the lithium battery for statically charging the lithium battery; another output end of the static power-taking circuit is connected with a null line; the output end of the lithium battery is connected with the input end of the control unit for supplying power to the control unit; the output end of the control unit is connected with one input end of the relay for controlling the switch-off or switch-on of the relay; and another input end of the relay is connected with the other end of the load for controlling the switch-off or switch-on states of the load. The lithium battery based single firing line power-taking apparatus has the beneficial effects that the power-taking apparatus has the relatively stable power supply, and time delay does not exist in turning off the load.

Description

technical field [0001] The invention relates to the field of smart home, in particular to a lithium battery-based single live wire power-taking device. Background technique [0002] Currently existing smart switches include a power supply unit, a main control unit, a touch unit, a drive unit and a wireless communication unit. With the rapid development of science and technology, smart home has become an emerging technology field that makes people's lives more convenient. Among them, the use of Internet of Things technology to realize intelligent control and remote control of home appliances, such as setting and Automatic control and remote control of electrical appliances are a basic technology in the field of smart home technology. Existing smart switches use wireless actuation relay technology, using a direct drive approach. However, due to the large driving power consumption required by the relay itself, and the higher energy consumption requirements of the portable ins...

Problems solved by technology

In order to solve this problem, some intelligent switches (hereinafter referred to as single-fire switches) that support single-fire wire power-taking have appeared on the market. The circuit may include single-chip microcomputer, radio module, relay or thyristor, etc.); but when these single-fire switches are actually put into use, they still show great limitations, mainly as follows: First, the stability of power supply is insufficient

Due to unstable power supply, it will cause failures such as "out of control" and "slow response"; second, "wild fire" phenomenon is prone to occur

Since the single-fire switch hopes to obtain as much current as possible from the single-fire circuit, when the loop load is a small current load such as an LED lamp, it is easy to activate the load to work, so that the LED lamp and the like appear fluorescent phenomenon visible to the naked eye in the off state. That is, there is a delay in turning off
