Title:
A WIRELESS LINKED AND NUMERICALLY CONTROLLED COLOR ILIGHTS SYSTEM AND CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2004/086825
Kind Code:
A1
Abstract:
A wireless linked and numerically controlled color lights control system. The system uses industrial power in a same network. It includes a general switch and a plurality of numerically controlled color lights which form network with power lines. The numerically controlled color lights include a wirelessly linked controller in which soft addresses are placed, and one or a plurality of color lights. The wirelessly linked controller includes a synchronous pulse extracting circuit, a control circuit of external industrial power and a drive circuit which are sequentially connected. The invention also discloses also a method. The method includes the following steps: A plurality of numerically controlled color lights are supplied power at the same time. Each numerically controlled color light extracts the synchronous pulse from periodical power signal and starts to count. When the number arrives at the soft addresses parameters set in the numerically controlled color lights, the numerically controlled color lights begin to perform set instructions and then return to the step and begin to recount. During the recounting, the numerically controlled color lights continue to perform the said instructions. The invention adds the synchronous pulse extracting circuit the soft addresses and control soft based of current color lights controller and realises the synchronization and the linking among the color lights. It may be applied to large-scale lighting engineering, avoid control wiring, reduce system cost and increase system flexibility.
