Abstract

The invention discloses a method for completely acquiring DALI (digital addressable lighting interface) signals and a DALI signal analyzer. The method is implemented by the aid of a lower computer and an upper computer, the DALI signal analyzer comprises the lower computer and the upper computer, the lower computer is used for acquiring the signals on a DALI bus and uploading decoded data to the upper computer, the upper computer is used for displaying and analyzing an operation interface and the data and acquiring information including high and low level values of the DALI signals, the content and the type of standard DALI signals, the error type of nonstandard communication signals and the like, communication data of a DALI system can be monitored, recorded and analyzed, and development, installation, debugging and maintenance of the DALI system and equipment thereof are facilitated. A communication protocol appoints communication data frame formats, data unit meanings and frame error detection and retransmission mechanisms of the upper computer and the lower computer, and high efficiency and stability of communication of the upper computer and the lower computer and accuracy of the bus data can be ensured.

Description

technical field

[0001] The invention relates to a lighting control system based on a digital addressable lighting interface, in particular to a method for completely collecting DALI signals and a DALI signal analyzer using the method. Background technique

[0002] DALI is an acronym for "Digital Addressable Lighting Interface Digital Addressable Lighting Interface". DALI is a data transmission protocol specially formulated for lighting control systems. It defines the digital communication method between lighting appliances (drive circuits of various lamps) and system equipment controllers (such as lighting controllers, sensors, etc.) . DALI supports the concept of "open system" to ensure that DALI devices produced by different manufacturers are compatible with each other. DALI has now become the IEC62386 series of international standards. In order to facilitate the monitoring, recording and analysis of the communication data of the DALI lighting control system, it is the ...
