Stage control system and method for digital multiplex (DMX) 512 intelligent distribution isolating amplifier

Abstract

The invention discloses a stage control system and a stage control method for a digital multiplex (DMX) 512 intelligent distribution isolating amplifier, which belong to the technical field of stage control and aim to realize the remote, centralized and intelligent interaction of stage equipment, finish various settings and set and acquire state data. The stage control system comprises a control system, wherein the control system consists of a master DMX512 intelligent distribution isolating amplifier, a plurality of concatenated slave DMX512 intelligent distribution isolating amplifiers, a receiving circuit of stage equipment and a wireless transmitter; output DMX512 signals of the master DMX512 intelligent distribution isolating amplifier can be connected to the DMX512 signal input of the slave DMX512 intelligent distribution isolating amplifiers, and can be concatenated for many times; and each group of intermediate and final output DMX512 signals is connected in series to the next stage equipment as the DMX512 signal input of the stage equipment, finally connected to the wireless transmitter at the tail end of the whole link, and wirelessly received by the master DMX512 intelligent distribution isolating amplifier to form a DMX512 feedback loop. By the system and the method, intelligent improvements of a stage equipment system can be achieved, working strength can be weakened, working efficiency can be improved, high speed, accuracy and safety can be ensured, and the occurrence of safety accidents is avoided.

Description

technical field [0001] A stage control system and method of a DMX512 intelligent distribution isolation amplifier proposed by the present invention belong to the technical field of stage control, and are especially suitable for controlling the stage by DMX512. Background technique [0002] Nowadays, the lighting equipment and equipment used on the stage for larger performances, such as effect lights, color-changing lights, follow-spot lights, laser lights, etc., are more and more digital lights, and there are as few such equipment as a performance device Hundreds, as many as thousands, and the control of landscape lights in buildings and buildings, they all follow the stage lighting control protocol issued by the American Theater Technology Association in 1986, that is, the DMX512 control digital transmission protocol. To accept the DMX512 protocol, each facility must manually perform some settings (such as DMX address code, working mode, parameter setting, etc.) before it c...

Problems solved by technology

For this reason, a large amount of manpower must be invested to adjust and test each equipment, and the workload of the staff is heavy and the efficiency is very low and error-prone

In the field work, because the equipment is often hoisted very high, and the strong and weak currents are mixed together, the temperature of the casing of some equipment is very high. Setting adjustments, testing and maintenance in such an environment pose a serious threat to the safety of personnel and equipment. Threats, occasional accidents of equipment damage and personal injury
