Joint control switch system and control method thereof

Abstract

The invention provides a joint control switch system and a control method thereof and relates to ht field of a smart home. The system comprises a first switch, a second switch and a control terminal.A first end of the first switch is connected with a live wire through utilization of a single wire power supply. A second end of the first switch is connected with a null line. The null line is connected with a controlled load. A third end of the first switch is connected with the second switch through utilization of a power wire, a ground wire and a signal line. The first switch and the control terminal are wirelessly connected. The first switch supplies power to the second switch through utilization of the power wire and the ground wire and communicates with the second switch through utilization of the signal line. The first switch detects a first switching control instruction, a second switching control instruction from the second switch or a third switching control instruction from thecontrol terminal and controls a switching state of the controlled load based on the first switching control instruction, the second switching control instruction or the third switching control instruction. According to the system and the method, exiting wiring is utilized fully, cost is reduced, and control efficiency, security and reliability are improved.

Description

technical field [0001] The present disclosure relates to the field of smart home, in particular, to a joint control switch system and a control method thereof. Background technique [0002] With the development of smart home technology and users' continuous pursuit of quality of life, home automation and intelligence have attracted more and more attention. Smart home can connect various home devices through the network, so as to realize centralized and automatic control, and provide users with comfortable, safe and convenient living space. [0003] In the prior art, in order to meet the needs of users to control the household equipment installed at the same location in different indoor locations, for example, in the bedroom and living room, to turn on or off the lamps in the living room, the household equipment can be used as the controlled load , connected in series with two single-pole double-throw switches, and the two single-pole double-throw switches can be respectivel...

AI Technical Summary

Problems solved by technology

[0004] However, this traditional joint control method, on the one hand, when the SPDT switch is closed and disconnected, the current or voltage in the circuit is unstable, which may easily cause damage to the controlled load, or bring other safety hazards. Poor; on the other hand, two SPDT switches connected in series are usually fixed on the wall or other locations respectively, which requires the user to move to the location where the SPDT switch is installed to realize the control of the controlled load, which is inefficient
