The mains on-off control circuit directly controls the switch of the light through the light access interface, and the other group is the control signal for controlling the lights controlled by other light control switches. After receiving the signal of this group, the control unit calls out the corresponding address and passes The power line carrier modulation and demodulation circuit sends a control signal to the light switch of the corresponding address, and the controlled light switch controls the corresponding light after receiving the signal through the power line carrier modulation and demodulation circuit.

Detailed ways

The utility model will be described in further detail below in conjunction with accompanying drawing (embodiment):

Referring to FIG. 1 , multiple groups of light control switches 8 are respectively connected between multiple groups of electric lamps 10 and AC 220V transmission lines 9 . Through the operating circuit in the light control switch 8, one of the light control switches is set as the encoding master, and the others are slaves. The addresses are programmed for all the machines through the master, and all corresponding address tables of the light control switches are sent to other slaves. Each light control switch stores the corresponding address or address table, and then it can work.

Referring to Fig. 2, the light control switch 8 includes a control unit 1, a power line carrier modulation and demodulation circuit 2, an operating circuit 3, a mains on-off control circuit 4, a low-voltage direct current power supply circuit 5, a mains access interface 6, and a light access interface 7 etc. The control unit is composed of a single-chip microcomputer and its peripheral circuits, a control circuit, and an electrically erasable memory. The mains on-off control circuit uses thyristors or relays to complete power switching. The low-voltage DC power supply circuit supplies power to the weak current part of the light control switch.

The control unit 1 is the central control part of the entire light control switch, and the single-chip microcomputer is used as the central control chip. Its functions include receiving and processing the demodulated digital signal sent by the power line carrier modulation and demodulation circuit 2 through the output terminal; The sent digital signal is sent to the input terminal of the power line carrier modulation and demodulation circuit 2 for transmission; the operation signal input from the operation circuit 3 is received and processed; and the local address code is stored.

The power line carrier modulation and demodulation circuit 2 receives the modulation signal coupled in from the mains line, and after demodulation, the restored digital signal is input to the single-chip microcomputer through the output terminal; the digital signal received from the single-chip microcomputer is modulated and amplified and then coupled to the mains line on the way.

The operation circuit 3 receives the user's operation signal and converts it into a signal recognizable by the single-chip microcomputer and sends it to the single-chip microcomputer.

The mains power on-off control circuit 4 receives the on-off signal sent by the control unit 1, and turns on or off the mains power for the controlled lamp.

The low-voltage DC power supply circuit 5 converts the AC power of the commercial power into a low-voltage DC power supply for the weak current part in the light control switch. The mains power access interface 6 is the entrance of the mains connection line. The lamp access interface 7 is an access port for connecting wires of the lamp.

In actual operation, the user can directly control the lights directly connected to the light control switch by inputting control commands through the operation circuit 3 of the light control switch. This process is that the control unit 1 controls the mains power on and off after receiving the input from the operation circuit 3 The control circuit 4 can also be used to input control commands for lights controlled by other light control switches to be controlled through the operation circuit 3. After receiving the commands of other light control switches to be controlled by the user, the control unit 1 calls out the corresponding address , through the power line carrier modulation and demodulation circuit 2, send a control command to the light control switch of the corresponding address, and the controlled light control switch will control the corresponding light after receiving the command through the power line carrier modulation and demodulation circuit 2. The mains on-off control circuit 4 can use a thyristor or a relay to complete power switching.

In this way, the user can control all the things at home at his convenient light control switch, without running around.

In order to be more convenient for the user, an infrared remote control receiving circuit can be added to the light control switch, and the user can control all the lights in the home through the remote control anywhere in the home.

By adding a voltage regulating circuit in the mains on-off control circuit 4, the user can also conveniently adjust the brightness of each lamp.
