Embodiment Construction

[0030] The present invention will be described in further detail below in conjunction with the examples, but the embodiments of the present invention are not limited thereto.

[0031] Such as figure 1 As shown, a lighting control system, which includes: a number of luminaire groups that use the DALI protocol for wired communication and use the ZLL protocol for wireless communication with each other, communicate with each luminaire group through the ZLL protocol and are responsible for communicating with the host computer The control bridge for communication, and the upper computer that controls each lamp group through the control bridge. Each lamp group includes a lamp group master control unit capable of transmitting and receiving ZigBee signals and capable of analyzing and processing ZLL and DALI protocols, and several DALI slave control units connected to the DALI bus interface of the lamp group master control unit. According to needs, the lighting control system may also ...

Abstract

The invention discloses a lighting control system which comprises an upper computer, a control bridge and a plurality of lamp groups. The upper computer controls the lamp groups through the control bridge, each lamp group comprises a lamp group main-control unit and a plurality of DALI (digital addressable lighting interface) auxiliary-control units, the DALI auxiliary-control units are connected on a DALI bus interface of the lamp group main-control unit in a hung manner, each lamp group main-control unit comprises a DALI bus interface circuit and a ZigBee transceiving module, each lamp group main-control unit and the corresponding DALI auxiliary-control units are in communication through a DALI protocol, the lamp group main-control units are in communication through the ZigBee transceiving module, and the control bridge and the lamp groups are in wireless communication through a ZLL (Zigbee light link) protocol. Under the premise that system convenience and user experience are not lowered, construction cost of the lighting control system is lowered effectively, and node capacity of a network can be improved substantially.

Description

technical field [0001] The invention relates to the field of distributed intelligent lighting control, in particular to a lighting control system. Background technique [0002] Digital Addressable Lighting Interface (DALI for short) and ZigBee Wireless Optical Link (ZigBee Light Link, ZLL) are two widely recognized lighting network communication protocols in the field of intelligent lighting. In the intelligent lighting system, the selection and construction of the lighting information communication network is very important, which determines the robustness, interoperability and ease of operation of the lighting system, and also determines the construction difficulty and cost of the intelligent lighting system. The first problem that needs to be solved to realize intelligent lighting. [0003] At present, a variety of standards for intelligent lighting networks have been formed internationally. Among them, the DALI protocol is a communication protocol dedicated to lighting ...
