Intelligent Lighting Control System And New Technology Research

According to the tendency of new energy and the energy-saving environment protection area, the dissertation designs the intelligent lighting system based on DALI and RFID, in order to meeting the basic illumination demand of people and taking most advantage of the outdoor illumination.. In total, the dissertation does the following research.Firstly, the dissertation introduces the basic concept of the intelligent lighting control system, points out the characteristics, functions and feasibilities of the intelligent lighting system. And, the basic content, principle and application of DALI have been elaborated also. Next, comparing with analog technology and bus technology, the dissertation analyzes the advantages of DALI in the lighting system. It introduces the main point of the RFID the developing history and status. Talk about the RFID application based on the intelligent lighting control system. This technology is very useful in monitoring and maintenance area.Secondly, a new type of the digital addressable lighting ballast is designed based on DALI and RFID. Ballast includes EMI filter, PFC section, microchip module, the electrical transfer circuit and the intelligent dimming circuit etc. And, through analyzing the functions, the dissertation figures out the components' choice and the circuit debug methods of the two prototypes above. The dissertation also studies the LC series resonance circuit of the fluorescent lamp in theory, analyzes the reason that the fluorescent lamp can be triggered.Thirdly, compared with the traditional RS-485 lighting control system, the system expands the lighting control area; it constructs the lighting system with three-tier configuration, which can realize the lighting system being integrated in BMS (Building Management System). And, the dissertation analyzes the communication and control principle of the system. In the management tier, the system realizes the TCP/IP communication, which based on TCP/IP protocol, between PC and ADAM4579. The communication between management tier and monitor tier is based on RS-485 bus, and the communication between monitor tier and locale tier is based on DALI protocol. DALI master control module can realize the transition between RS-485 data and DALI data. DALI data is coded in Manchester coding method. So, it completes centralized control and distributed management in the lighting system based on DALI, which has various functions, such as digital addressing, stepless dimming, grouping, query and preset lighting scene, etc.Fourthly, the solution of the intelligent lighting system based on genetic algorithm is used .After analyzes the significance of using artificial intelligence in the lighting system, it designs the specific mathematical model, which is chosen to relate the internal plane illuminance, at a given point in any room, to the outdoor natural light illuminance. It also proposed the solution, which can realize the optimization of the model by using genetic algorithm, analyzes the principle of applying genetic algorithm to the intelligent lighting system based on DALI, which can make the most of natural light and save the energy.Lastly, a new architecture of the intelligent lighting control system is built up for the poor environmental illumination change response of the current lighting control system, the RFID technology is used for the direct communication between the lighting fixture and the illuminance sensor to speed up the adjusting speed of the environment illumination. The control module based on Adaptive Neighborhood Algorithm is established for the more accurate control. Verification tests are conducted based on Adaptive Neighborhood Algorithm, and the results showed that the various illuminance sensors converged to the preset target illuminance in a very short time. It is also confirmed that the system can respond adaptively to the movement of illuminance sensors.
