Lamp DMX address setting system and method

Abstract

The invention relates to a lamp DMX address setting system which comprises a DMX controller, a 485 bus and at least two lamps connected in sequence. Wherein the lamp comprises a control module, a 485 module and a single-line input and output circuit, and the control module is connected with the 485 module and the single-line input and output circuit; the DMX controller is connected with the 485 modules of the at least two lamps which are connected in sequence through a 485 bus; and between the at least two adjacent lamps which are connected in sequence, the single-line input and output circuit of the rear lamp is connected with the control module of the front lamp. According to the system provided by the invention, address codes are transmitted by applying the 485 bus and the 485 module, and are transmitted by using a differential transmission mode through the 485 bus and the 485 module, so that compared with the prior art, the capability of inhibiting common-mode interference is improved, and a longer transmission distance can be realized, thereby meeting the requirement of DMX address setting of a large-scale lamp system.

Description

technical field [0001] The present invention relates to the technical field of lamps, and more specifically, includes a lamp DMX address setting system and method. Background technique [0002] At present, most of the lamps on the market are controlled by DMX512 protocol, and the DMX512 protocol requires each lamp to be set with a DMX address. At present, the addresses of lamps and lanterns are set one by one mainly through automatic sorting method. The existing single-line automatic sorting method uses an unbalanced transmission method to transmit address codes to the lamps, which has poor common-mode suppression ability, and the address of the lamps is very easy to be interfered during the single-line transmission process, especially when the long-distance transmission has a high bit error rate, which affects the use. . Contents of the invention [0003] The first object of the present invention is to provide a DMX address setting system for lamps. This system uses 485...
