Digital addressable lighting system and method integrating functions of safety protection and emergency recourse

Abstract

The invention discloses a digital addressable lighting system integrating the functions of safety protection and emergency recourse and a control method. The digital addressable lighting system integrating the functions of safety protection and emergency recourse comprises a personal computer (PC), a master controller and 1 to 64 nodes, wherein the 1 to 64 nodes are divided into lighting control nodes, lighting execution nodes, safety-protection control nodes and a safety-protection execution node; the PC is connected with the master controller by an RS232 serial port, and the master controller, the lighting control nodes, the lighting execution nodes, the safety-protection control nodes and the safety-protection execution node are all hung and carried on a digital addressable lighting interface (DALI) bus; and the system is based on a DALI protocol and follows the specifications of the DALI buses of a plurality of controllers. By setting the continuous inquiring time and the random-number collision waiting time of DALI bus nodes, the lighting control nodes, the safety-protection control nodes and the safety-protection execution node are additionally arranged on the basis of a traditional DALI lighting system according to the digital addressable lighting system integrating the functions of safety protection and emergency recourse and the control method so as to finish a set of DALI lighting system with the functions of safety protection and emergency recourse. A system integrating the function of safety protection is compatible to the traditional DALI lighting system; and the control flexibility is increased, and the total owning cost of a user is also lowered.

Description

technical field [0001] The invention belongs to the technical field of intelligent lighting control, in particular to a digital addressable lighting system and method integrating security and emergency help functions. Background technique [0002] The Digital Addressing Lighting Interface (DALI) protocol is a dedicated protocol for fluorescent lamp lighting control systems. It was included in the International Electrotechnical Commission standard IEC60929 in 1994. The DALI agreement has been widely supported by well-known lighting equipment manufacturers in developed countries such as Philips and OSRAM. The non-profit organization DALI-AG in Germany is responsible for product certification and management; the purpose of the agreement is to ensure that dimming electronic ballasts produced by different manufacturers have mutual Changeability represents the general trend of the current lighting technology in the direction of digitalization, simplicity and reliability. With the...

Problems solved by technology

Compared with the traditional inductive fluorescent lighting, the digital addressable lighting control system has a disadvantage of higher initial cost. In the case of saving electricity but not saving money, the digital addressable lighting control system cannot be expected to be generally recognized by the whole society. Therefore, Reducing the user's total cost of ownership is a key issue that needs to be solved urgently
