DALI (Digital Addressable Lighting Interface) signal generator communication protocol on basis of USB (Universal Serial Bus) interface and device

Abstract

The invention discloses a DALI (Digital Addressable Lighting Interface) signal generator communication protocol on the basis of a USB (Universal Serial Bus) interface. The communication protocol comprises the following steps that: S1, an upper computer sends out a command of the communication protocol; S2, the upper computer waits for response of a DALI signal generator lower computer; S3, the DALI signal generator lower computer receives the command sent by the upper computer; S4, the DALI signal generator lower computer judges command data of the upper computer, the DALI signal generator lower computer extracts a first byte and judges the byte, then data is processed according to a set program inside the first byte, and the data is sent to the upper computer, and receiving is ended; and S5, the upper computer checks whether the DALI signal generator lower computer responds or waiting for the response of the DALI signal generator lower computer is timed out, and a result is displayed, wherein the command comprises an inquiry command and a DALI command and the DALL command also comprises a custom command and a standard command.

Description

technical field [0001] The invention relates to the field of intelligent lighting control systems, in particular to a DALI signal generator communication protocol and device based on a USB interface. Background technique [0002] DALI is an acronym for Digitally Addressable Lighting Interface, which means Digitally Addressable Lighting Interface; it is a data transmission protocol specially formulated for lighting control systems, which defines lighting controllers, such as lighting control panels or sensors and Communication method between lighting fixture drivers. DALI has now become the international standard of the IEC62386 series. Many companies in the market have launched lighting control systems or equipment that meet the DALI international standard; companies such as Philips, Osram, and Tridonic have all launched relatively complete DALI equipment. The supporting system configuration software can constitute a DALI lighting control system that meets the application r...

DALI has now become the international standard of the IEC62386 series. Many companies in the market have launched lighting control systems or equipment that meet the DALI international standard; companies such as Philips, Osram, and Tridonic have all launched relatively complete DALI equipment. The supporting system configuration software can form a DALI lighting control system that meets the application requirements; however, the system configuration software of these companies is limited to the signal generation and communication of the international standard DALI standard commands and non-standard commands defined by their own companies, and users cannot generate their own. Defined DALI commands; at the same time, there is no signal generator product that can be customized by users to generate DALI commands
