Description
Technical Field
The invention relates to an intelligent double-control switch, in particular to an intelligent double-control switch system compatible with traditional multi-path double-control switch wiring.
Background
The working principle of the traditional mechanical double-control switch is that 2 single-pole double-throw switches are connected in series by using a river crossing line, and the effect that the on-off of electrical appliances can be controlled by the 2 switches is achieved.
The existing intelligent double-control switch has uneven wiring modes, and generally comprises the following types:
1. based on the intelligent single-control switch, the wireless communication technology is utilized to realize the double-control function through the wireless communication between the two intelligent switches
However, the intelligent dual-control switch has the following disadvantages: the physical connection between the two switches is only for getting electricity, actually only the first single-control intelligent switch controls the electric appliance, and the second single-control intelligent switch only tells the first single-control intelligent switch to control the electric appliance through wireless communication, although the mode can realize double control and multiple paths, the mode is false double control, only one controller is added compared with the common intelligent switch, and the wiring mode is far different from the traditional mechanical double control switch, the practical application is inconvenient, and the scheme can not be used when the distance between the two intelligent switches is far; and the old circuit is not supported to be modified, and rewiring is needed. The single-control intelligent switches need to be used in pairs, one single-control intelligent switch cannot be matched with a traditional mechanical double-control switch, and the two switches are close to each other;
2. based on the intelligent double-control switch, the double-control function is realized by using special wiring
The intelligent double-control switch has the following disadvantages: the two switches are physically connected in a complex manner, a high-voltage alternating current line and a low-voltage direct current signal line exist, multi-path double control is not supported, old circuit transformation is not supported, rewiring is needed, the switches need to be used in pairs, and a single-control intelligent switch cannot be matched with a traditional mechanical double-control switch for use.
3. Based on an intelligent single-control switch, the double-control function is realized by using butt joint power supply, for example, the Chinese patent application with the publication number of CN106249631A
Although the intelligent double-control switch realizes the working principle of the traditional mechanical double-control switch, the mode can only realize a single-path double-control switch and is not completely compatible. Because the number of relays used is large, the cost is high, and because the power consumption is high when the switch uses a common relay to work, the power of the serially connected electric appliance bulbs cannot be too low, otherwise, intermittent flashing (commonly called as a ghost fire phenomenon) occurs.
