Abstract

The invention discloses a distributed DALI (Digital Addressable Lighting Interface) lighting control system and a method thereof. The system comprises a DALI gateway, a plurality of ballast nodes and a plurality of control nodes, wherein the DALI gateway and the control nodes serve as main control equipment, the ballast nodes serve as subordinative control equipment, the DALI gateway can control all the control nodes and all the ballast nodes, and the main control nodes can control the ballast nodes bond with a radio frequency identification (RFID). After the system is established, the DALI gateway automatically allocate addresses for the control nodes or the ballast nodes accessing a network newly, thereby reducing work load of engineering staff. Network communication among system equipment is performed through an anti-collision token transmission strategy based on master-slave equipment, thereby meeting communication requirements on a network with multiple masters and multiple slaves, and enhancing utilization efficiency of the network. By virtue of the RFID which is bond with the ballast nodes in a room, light in the room can be intuitively controlled by a user, so that the usability of the system is improved.

Description

technical field

[0001] The invention relates to a lighting control system, in particular to a distributed DALI lighting control system and a method thereof. Background technique

[0002] With the development of society and economy, people's demand for energy is increasing. With the intensification of oil and electric energy energy crisis, the development of new energy and energy conservation and emission reduction have become the common demands of all countries in the world. "Green Lighting Project" is a lighting concept proposed by the US National Environmental Protection Agency in the early 1990s from the perspective of energy conservation and environmental protection, and has been valued by the United Nations and countries around the world. Governments of various countries actively adopt corresponding policies and technical measures to promote the implementation and development of green lighting projects.

[0003] In traditional buildings, the lighting system consumes 50...
