Landscape Fuzzy Control System Based On Scene Changing Adaptively

With the country's prosperity and the development of social civilization, critical infrastructure as the city lights, landscape lighting has become the city reflects the city's image and show an important part of civilization. With the deepening of the city lighting engineering,a series of problems of the traditional mode of landscape lighting and lighting control are more and more prominent.For the current lighting, landscape lights lighting control programs existing several problems: lighting control programs is single and setting time and effort, with the general lighting effects,and lighting programs is not an option according to the actual need to make corresponding changes, while difficult to achieve energy-saving lighting control purposes and other issues, the paper design a set of new adaptive control theory, with the scene, program, and program scheduling to be a combination of distributed intelligent control solutions, meeting the lighting environment with problems brought about by the area, time, weather changes , while using Distributed master-slave structure can overcome a wide range of lamps, geographically dispersed, hard wiring and other issues.Around the subject, this paper carried out the following research works:①Analysis of landscape lighting control system design requirements. For lighting solutions being single in the design of conventional lighting control mode and lighting solutions can not demand change problem, a scenario based adaptive control system design Landscape changes in the solution.②Lighting environment and the impact of information on detection: for the real-time information on lighting, pedestrian movement tourist information, the system time zone information location, lighting environment illumination extract information, and comprehensive consideration of the special elements of landscape and garden lighting to achieve a lighting Description of the environment.③Landscape lighting scenes library generation: conventional lighting control mode is always single and fixed;made a scene lighting modes; establish a mapping relationship between the scene and landscape elements, namely, by the scene lighting control system to achieve control;the establishment of landscape lighting Scenario library to achieve multi-modal system control functions.④Scene Adaptive lighting control: The system uses adaptive thinking, the input of environmental information through the fuzzy adaptive decision-making, to build a fuzzy control rules, and through the analysis of external information, to correct its own control parameters, and select or modify the current lighting Scenes, to acheive lighting control effect.⑤Implementation of the system software. By using the developing proof of"Visual Basic+ SQL Server2000", it realized each functional module of the system. The subject to the research,scene change based on adaptive control system has been running in the lighting control system of Landscape Logistics Engineering College of Chongqing,being very good application, good stability and energy efficiency.
