Description
Technical Field
The invention relates to a DMX system, in particular to a DMX system for recovering RDM states in real time.
Background
Currently, in a professional dimming control application system, we generally transmit digitized dimming control data according to the DMX512 protocol to implement dimming control. The DMX512 protocol is a technical standard for asynchronous serial transmission of digital control data in a system for controlling lighting equipment and accessories, and mainly comprises a physical platform for implementing control data transmission, electrical characteristics of a signal interface, signal timing on a system data bus, a data packet format and the like. In a dimming control application system built according to the DMX512 protocol, the direction of the signal flow on the control data transmission bus is determined, i.e. the control data is always sent from the control device, transmitted unidirectionally via the data bus to the respective controlled device. The control device ensures the real-time performance and the correctness of the control data by continuously and repeatedly transmitting the control data. Since the technical standard does not explicitly define the inverse transmission of information, the operator cannot know any composition of the application system and the operating state information of the controlled device through the control device itself. In order to allow an operator to know information about an application system through the control device itself, technical standards for RDM (remote device management) have been developed.
