Description
WIFI INTELLIGENT SWITCH CONTROL SYSTEM POWERED
BY SINGLE LIVE LINE
TECHNICAL FIELD
This disclosure generally relates to the technical field of switches and intelligent switches, and more particularly, to a WIFI intelligent switch control system powered by a single live line.
BACKGROUND
A WIFI intelligent switch is an Internet-based unit capable of realizing an intelligent switch control of the circuit through utilizing the combination and programming of a control panel and electronic components. The switch control, also known as the point-to-point control, is simple and easy to realize, and thus is widely adopted for the control of household appliances and lighting fixtures. However, it is difficult for conventional switches to meet the requirements of further improving their control modes and saving cost.
In a conventional switch control mode, the control quantity has only two states in a control cycle, meaning that the control quantity is either a fixed constant value in an on-state or zero in an off-state. Both the two states require an external force imposed manually or mechanically to alter the state of the switch. In the process of a manual switch control, different switch control states and combinations of wiring are manually chosen to achieve a one-way or two-way control mode according to the control requirements.
The switch mode using an external force to achieve the alteration of control state has shortcomings such as the small number of simultaneously-controllable switches, limited control distance and low intelligence. The adoption of a conventional WIFI intelligent switch may solve the aforesaid technical problems. In common house decoration, the switch box inside the wall body has no neutral line but a live line going through. The mechanical switch turns on/off the light through switching-on/off the live line. However, most of the conventional WIFI intelligent switches are powered by a neutral line and a live line, making the power supply from a single-live-line wall socket impossible. Under such circumstances, when installing an intelligent switch, a neutral line must be added such that the intelligent switch can be powered. The rewiring not only destroys the wall body but sharply increases the material and labor costs, resulting in a poor user experience.
To solve the technical problems of conventional common switches relating to the small number of simultaneously-controllable switches, limited control distance and low intelligence, as well as the technical problems of conventional intelligent switches relating to the one-way control and power supply requiring a neutral line and a live line, the present disclosure provides a novel WIFI intelligent switch control system, which is powered by a single live line, and possesses one-way/two-way control modes.
