Lamp automatic address-writing method based on DMX512 protocol

Abstract

The invention relates to the field of lamp lighting, and provides a lamp automatic address-writing method based on a DMX512 protocol, so as to solve the problem of low efficiency of an address writing method of the existing receiving chip. The lamp automatic address-writing method comprises the steps of: connecting a lamp end with a DMX512 controller; setting an address line port of the DMX512 controller to be low level after power on; sending address information to the lamp end by the DMX512 controller circularly; receiving the address information by the lamp end; and reading the address information saved in a storage and writing addresses after the lamps are electrified again. The technical scheme provided by the invention can achieve the effect that the addresses of all lamps can be written at a time without writing the address for each lamp separately, and the efficiency of the address writing method is high.

Description

technical field

[0001] The invention relates to the technical field of lamp lighting, in particular to a method for automatically writing addresses of lamps based on the DMX512 protocol. Background technique

[0002] At present, in the field of LED lighting and landscape lighting, there are monolithic integrated DMX512 protocol receiving chips on the market, but the power of the corresponding lamps is generally very small (about 15W). For writing addresses of high-power lamps and lanterns, the efficiency of using the current address writing method of the receiving chip is low, and the difficulty of on-site construction is relatively large. Contents of the invention

[0003] 【Technical problems to be solved】

[0004] The purpose of the present invention is to provide an automatic address writing method for lamps based on the DMX512 protocol, so as to solve the problem of low efficiency of the current address writing method for receiving chips.
