Abstract

The invention discloses a device and a method for converting DALI (digital addressable lighting interface) protocol data and a lighting control system. The device comprises a DALI unit, a PLC (programmable logic control) unit and a control unit. DALI bus differential signals and first TTL (transistor-transistor logic) intermediate level signals can be converted by the DALI unit; PLC signals carried on electric power lines and second TTL intermediate level signals can be converted by the PLC unit; the first TTL intermediate level signals and the second TTL intermediate level signals can be converted by the control unit on the basis of DALI protocol stacks. The device can work in two working states. The device and the lighting system have PLC receiving and transmitting functions, the DALI bus differential signals can be transmitted via the electric power lines, DALI terminals can be addressed and controlled on the basis of DALI bus protocols, large-scale and high-expansibility requirements of the intelligent lighting control system can be met, and the device, the method and the lighting control system have the advantages of energy conservation, high efficiency and flexibility in operation.

Description

technical field [0001] The invention relates to the technical field of lighting control, in particular to a DALI protocol data conversion device, method and lighting control system. Background technique [0002] With the advancement of electronic technology and the improvement of the quality of life, people's requirements for lighting equipment are no longer satisfied with simple switch control, but an intelligent lighting control system that is energy-saving, efficient, and flexible in operation. At present, there are many lighting control protocols commonly used in intelligent lighting control systems. Among them, DALI (Digital Addressable Lighting Interface, Digital Addressable Lighting Interface) is widely used in the field of intelligent lighting control due to its low development cost, low difficulty in system development, easy expansion, and strong practicability. [0003] DALI is an industrial standard for lighting electronic ballast control. DALI bus has the advant...
