Embodiment Construction
[0042] The gist of the present invention is to design a lighting control system based on the DMX512 protocol. The following will be described in detail in combination with specific implementation methods, so as to have a more in-depth interpretation of the technical features and advantages of the present invention.
[0043] The system structure diagram of the present invention is as attached figure 1 . The lighting control system of the present invention includes four parts: a host computer 101 , a DMX signal generator 102 , a DMX signal decoder 103 and a lamp 104 . The host computer 101 can be an ordinary PC (internal setting control software), and the host computer software is mainly responsible for configuring the working parameters of the DMX signal generator 102 and monitoring the working status of the lamps. The upper computer 101 is connected with the DMX signal generator 102 through an Ethernet interface, and its communication protocol adopts the TCP / IP protocol, and...

Description
technical field [0001] The invention relates to the technical field of lighting control, in particular to a lighting control system and method based on the DMX512 protocol. Background technique [0002] LED (Light Emitting Diode, light-emitting diode) is a solid-state electronic device that directly converts electrical energy into light. It has many excellent characteristics such as high efficiency, no pollution, small size, long life and high reliability. Especially in terms of energy saving and service life, LED technology has gradually penetrated into the lighting industry due to its huge potential. LED lighting technology is considered to be one of the new solid cold light sources most likely to enter the field of general lighting in the 21st century and one of the most promising high-tech fields. [0003] The control method of LED lighting products generally adopts the bus control method and the SPI (Serial Peripheral Interface, Serial Peripheral Interface) cascade con...
