Embodiment Construction

[0011] The focus of the dimming control application system established by the DMX512 protocol is not control, but configuration to realize one-way remote management of equipment. The DMX512 protocol is developed for dimming control applications. The control device plays a very important role in any dimming control application system. It is the soul of the entire application system and masters the dominance of data transmission in the application system data network; the controlled device is the ultimate embodiment of the actual function of the application system. ; In the dimming control application system, the control device performs unidirectional control on the controlled device. Under normal circumstances, lamps without RDM function need to be set separately through the operation panel. When there are many lamps and the hanging lamp stand is very high, the operation is very inconvenient, cumbersome, and unsafe, and the RDM configuration is embedded in the controlled device...

Abstract

The invention discloses a method for configuring a RDM function of a lamp device based on DMX512, comprising steps of staying in a numerical value A segment for n seconds by a control channel, entering a controlled device parameter configuration mode, turning off function output control, combining a first channel numerical value C and a second channel numerical value D which are corresponding to a DMX address into a DMX address of the currently controlled device, setting the channel numerical value E, wherein E=C*256+D, E is only effective when the DMX address is greater than 0 and smaller than 513, the numerical value F of the third channel represents the channel mode of the controlled device, the area segmentation numerical value is utilized to express, and the various numerical value segments express various channel modes, staying in the numerical value B segment for m seconds by the control channel, entering a controlled device parameter confirmation mode, storing the configuration result of the first step by the controlled device, returning the value of the control channel to 0, entering a new channel mode and operating according to a new DMX address by the controlled device. The method disclosed by the invention can perform remote RDM configuration on the lamp through the regular DMX512 control platform, the operation is easy without adding any hardware.

Description

technical field [0001] The invention relates to LED lamps, in particular to a method for configuring RDM functions of lamps and lanterns based on a DMX512 console. Background technique [0002] RDM is short for Remote Device Management. At present, in professional dimming control application systems, we usually transmit digital dimming control data according to the DMX512 protocol to realize dimming control. The DMX512 protocol is actually the abbreviation of a technical standard in the professional dimming industry. It is a technical standard for asynchronous serial transmission of digital control data in the system of controlling lighting equipment and accessories. The main content includes the physical platform for implementing control data transmission. , Electrical characteristics of the signal interface, signal timing on the system data bus, data packet format, etc. The agreement was originally proposed by USITT in 1986, and a revised version was released in 1990.
