Digital addressable illumination control system and method thereof

Abstract

The invention discloses a digital addressable lighting control system and a method thereof. The system consists of master nodes and slave nodes numbered from 1 to 64 which are hung and connected on a DALI bus, all the sensors and a PC on which DALI application software runs are connected with the main nodes, and the slave nodes comprise two parts of DALI interface circuits and electronic dimming ballasts and serve as a system actuator for driving fluorescent lamps. The actuator controls the fluorescent lamps according to commands of the main nodes and the preset working parameters, the slave nodes are taken as the system actuator, a control unit thereof reads the real-time working states of the fluorescent lamps and an output module and feeds back to the main nodes by the DALI bus, then the digital addressable lighting control system can not only feed back the real-time state of the control unit of the actuator, but also feed back the real-time states of an executive unit and controlled objects, and maintenance personnel and a user can grasp the full picture and the details of the system. The digital addressable lighting control system adopts the electronic ballasts with separated easily damaged parts and non-easily damaged parts, and only the easily damaged parts need to be replaced during the life cycle of the actuator, thereby effectively reducing the overall owning cost of the user.

Description

technical field [0001] The invention relates to an intelligent lighting control system and its method, in particular to a digital addressable lighting control system and its method. Background technique [0002] There are two types of devices in the intelligent lighting control system: sensors (Sensor) and actuators (Actor). Sensors refer to a type of equipment that accepts user commands or perceives changes in environmental parameters, such as panel switches, remote controls, dimming knobs, PC man-machine interfaces, and sensors that can sense parameters such as movement, temperature, humidity, and brightness, and act as a lighting control system. command issuer and system status monitor roles. Actuator refers to a type of equipment that drives the controlled object according to the sensor command and the preset working parameters of the actuator, such as electronic dimming ballasts, electronic switches, curtain drivers, etc., acting as the command executor and system stat...

Problems solved by technology

[0005] Compared with the traditional inductive fluorescent lighting, the DALI lighting control system has a disadvantage of higher initial cost. In the case of saving electricity but not saving money, the DALI system cannot be expected to be generally recognized by the whole society. Therefore, reducing the overall cost of ownership of users is expected. Key Issues to Solve

Drawing on the idea of ​​separate design of high-priced non-fragile ballasts and cheap fragile starters in traditional fluorescent lamp lighting, the patent "Electronic Ballast with Replaceable Consumable Parts" (publication number CN1873857) proposes an electronic ballast The split structure is composed of the ballast shell and the externally inserted triode. The above split structure can indeed reduce the user's total cost of ownership, but it leads to a series of problems such as the reliability and safety performance of the ballast.

The patents "HID electronic ballast with split structure" (publication number CN2932081) and "electronic ballast for split-type high-pressure gas discharge lamps" (publication number 2904560) proposed that the ballast be designed as a main and auxiliary shell Split structure, the connection between the two shells in the above split structure depends on the number of wearing parts or high-heating devices, a large number of main and auxiliary shell connections lead to increased installation complexity, ballast reliability and gas Decreased density
