Lamp based on DMX512 protocol, light control terminal, control system, and control method

Abstract

The invention discloses a lamp based on a DMX512 protocol, a light control terminal, a control system, and a control method. The control terminal comprises a communication unit, a terminal control unit, a signal conversion unit, and a power supply. The terminal control unit communicates with a control main unit through the communication unit, and the signal conversion unit converts a control signal outputted by the control unit into a DMX512 signal, and transmits the DMX512 signal to the DMX512 chip of each controlled lamp or lamp group. According to the invention, the control main unit or a remote control main unit transmits the control signal to the control terminal through wireless transmission or a cable, and the control terminal and the controlled lamp or lamp group are connected together to form a body, thereby guaranteeing the long-distance reliable transmission of the control signal, and achieving the large-range networking of an LED lamp and the lamp based on the DMX512 protocol. The control terminal can achieve the point-to-point synchronous control, also can achieve the point-to-line and point-to-plane synchronous control, and eliminates a conventional console which is heavy, consumes a large amount of power and is poor in reliability.

Description

technical field [0001] The invention relates to a device based on the DMX512 protocol, especially a lamp or a lamp group and its control terminal, control system and control method. Background technique [0002] Considering the impact of interference and transmission distance, generally do not use wireless commands on DMX512 lights, but use DMX512 control signals to control wash lights, that is, computer→DMX512 controller→signal amplifier→multiple wash lights. In addition, DMX512 lamps can be controlled simply, and may also be controlled by a timer. To this end, a DMX512 lighting console is needed, and then the console converts the control signal into a DMX512 control signal, and then the DMX512 integration box sends the final control signal. Furthermore, buildings or architectural models also use wash lights or moving head lights. [0003] However, the DMX512 control signal needs to be sent continuously, if the distance is too far, the signal will be unstable. Therefore,...
