Embodiment Construction

[0052] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0053] The lighting control method of the present invention is accomplished by relying on the main controller connected to the power line and the decoding controller connected to each controlled lamp, and the steps are as follows:

[0054] (1) The main controller converts the received lighting control signal into a transmission data signal, which includes a start bit, a command bit, a lamp address bit, a lamp brightness data bit and an end bit arranged in sequence. It is A set of data sequences consisting of "0" or "1";

[0055] (2) The main controller divides the sinusoidal waveform in the AC signal on the power line into multiple waveform segments in turn, and changes the waveform of each waveform segment so that the waveform segment is in the state of two waveforms, and a plurality of waveform segments form a Waveform data group, the sum of the number of ...

Abstract

A lighting control method is completed by a main controller and a decoding controller, wherein, the main controller encodes the lighting control signal into a transmission data signal composed of '0' or '1', and then converts the transmission data signal into a waveform data group that can be transmitted by the electric power line to transmit to the decoding controller, the decoding controller analyzes the lighting control data of the corresponding lamp from the received waveform data group, and then performs lighting control to the lamp. A lighting control system made up by the method, principally includes a main controller, a plurality of decoding controllers and lamps connected to the decoders. The invention has strong anti-interference capability and high reliability, does not has anyrestrictions to the transmission distance, and has little effect on the power grid factor; the invention only uses the existing electric power line network, can effectively perform reconstruction of lighting energy-saving engineering without increasing any cable, has very low manufacturing and installation costs, and can construct intelligent lighting system with different functions by combining different lighting control software.

Description

technical field [0001] The invention relates to an illumination control method and an illumination control system manufactured according to the method. Background technique [0002] Traditional lighting systems are based on single-wire switches, which cannot respond to and realize remote dimming control requirements; therefore, people use wired methods to implement control data communication to achieve dimming control of traditional lighting. In the early days, people used analog signals from zero volts to 10 volts to control the dimming of traditional lighting, but this method has poor flexibility and cannot control a single lamp in a system. Since the 1980s, people began to use the bus (BUS) system, such as Digital Addressable Lighting Interface (Digital Addressable Lighting Interface, DALI) technology to control the dimming of traditional lighting systems. This technology mostly uses two-wire control cables; later wireless The network has the advantages of convenient net...
