Embodiment Construction

[0045] The control terminal based on the DMX512 protocol of the present invention includes a communication unit, a terminal control unit, a signal conversion unit, and a power supply; the terminal control unit may include a time synchronization module, a GPS module / Beidou module, and a control module, and the terminal control unit communicates through the RS485 interface and wireless The module communicates with the control host; the power supply includes an AC / DC module, which converts the external 220V AC power into low-voltage DC power supply for the control terminal; the signal conversion unit converts the control signal output by the control unit into a DMX512 signal and sends it to each controlled lamp or The DMX512 chip of the light group. A storage unit for storing emergency programs can also be installed in the terminal control unit. When the control host fails or the power is cut off, the emergency program can independently perform basic control on the controlled lamp...

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,...
