Embodiment 1

[0042] Please refer to figure 1, is a structural schematic diagram of a light control system in an embodiment. The light control system is used to adjust the brightness of the controlled light 5. The light control system includes a light control signal generating device 1, a light control signal output device 2, a light control signal The receiving device 3 and the lamp control adjusting device 4. The light control signal generating device 1 is used to output a light control adjustment signal transmission instruction to the light control signal output device 2 . The control signal output device 2 is used to respond to the lamp control and adjustment signal transmission instruction, modulate the lamp control and adjustment signal into a voltage square wave signal, and transmit it to the lamp control signal receiving device 3 through the power line of the controlled lamp. The lamp control signal receiving device 3 is used for demodulating the lamp control and adjustment signal ...

Embodiment 2

[0054] Please refer to Figure 11 , is a schematic flowchart of a light control method in another embodiment, the light control method is used to adjust the brightness of the controlled light, including:

[0055] Step 110, modulating the lamp control signal into a square wave signal.

[0056] When the light control signal generating device receives a light control adjustment signal transmission instruction, it modulates the light control adjustment signal into a voltage square wave signal according to a preset encoding method. In one embodiment, the preset encoding method is Manchester encoding.

[0057] Step 120, boost the square wave signal and send it out.

[0058] The lamp control signal generating device is also used to boost the voltage square wave signal and transmit it to the lamp control signal receiving device through the power line of the controlled lamp.

[0059] Step 130, step down the received square wave signal.

[0060] The light control signal receiving de...

Abstract

The invention discloses a lamp control system which comprises a lamp control signal generating device, a control signal output device, a lamp control signal receiving device and a lamp control adjusting device. When receiving a lamp control adjusting signal transmission instruction, the lamp control signal generating device modulates a lamp control adjusting signal into a voltage square wave signal, boosts the voltage square wave signal and then transmits the voltage square wave signal to the lamp control signal receiving device through a power line of a controlled lamp. And the lamp control signal receiving device reduces the voltage of the received voltage square wave signal and demodulates the voltage square wave signal after voltage reduction so as to obtain a lamp control adjusting signal. The lamp control adjusting device controls the lighting state of the controlled lamp according to the lamp control adjusting signal. The transmitting end firstly boosts the modulated lamp control and adjustment signal and then transmits the boosted lamp control and adjustment signal, and the receiving end demodulates the boosted control and adjustment signal after reducing the voltage, so that the transmission distance of the lamp control and adjustment signal is farther, and the anti-interference capability is stronger.

Description

technical field [0001] The invention relates to the technical field of intelligent lamp control, in particular to a lamp control system and a lamp control method. Background technique [0002] Lighting is a measure to use various light sources to illuminate working and living places or individual objects. Lighting is not only to make the environment bright, but also to adjust according to the actual needs of the specific lighting environment (such as lighting brightness and color, etc.). Smart lights The control system is used to adjust the brightness of the lighting. Generally, the light control signals of intelligent light control systems are communicated through PLC (Power line Communication), but the data transmission distance of power line communication is short and the anti-interference ability is poor. Contents of the invention [0003] The technical problem to be solved in this application is how to improve the transmission distance and anti-interference ability o...
