The Research And Development Of Classroom Lighting Intelligent Control System

Recent years, with the rapid development of economy and society, the demand forenergy is increasing and the contradiction between energy supply and energy demand isbecoming increasingly obvious. And the disordered exploitation of energy brings issues suchas energy waste and environment pollution. Therefore, our country has treated energyconservation, emissions reduction and environmental protection as an important systematicproject to promote the development of the economy and society and strongly support thestudy of energy-saving control technology. In the secondary vocational school where theauthor works, the traditional lighting way of the building has many disadvantages such asenergy waste, complex lines, short service life of lighting lamps and lanterns and so on, whichwill bring unnecessary economic loss to the school and does not conform to the policies ofenergy conservation and emissions reduction formulated by the state. Therefore, this thesistakes the building lighting system as the research object, and carries out the research in viewof the classroom lighting intelligent control system. The main work is as follows:This thesis analyses the using characteristics of the classroom and designs the lightingintelligent control system for the teaching building In view of demand of users for indoorlighting. The hardware design is on the basis of the original building and without the changeof lines and original lighting lamps and lanterns, using low engineering material anddecreasing the artificial loss, to complete the revolution of the classroom lighting control forexisting buildings. Whole lighting control system takes the central microprocessor as corepart, the light signal, clock signal, keyboard control as the input signal and relay drive circuit,controlled lamps and lanterns and digital tube display as output, reflecting the design conceptof controlling the commercial power with the weak power and solving the problems existed inthe traditional lighting control so as to realize the goal of environmental protection and energysaving.This thesis also researches the software design of the intelligent lighting control system,most of which is the software design of intelligent master controller, including the mainprogram module of the system monitoring, analog and digital signal gathering, the clockcontrol, keyboard human-computer interaction and so on, which saves time for the system andimprove the operation efficiency. The test work of the intelligent lighting control system isalso completed, which firstly carries out the static debugging in view of the hardware issueand meanwhile completes the framework debugging in terms of software and then combinesboth of them for an overall dynamic debugging, at last performs the debugging of generalsituation and proposes solutions to the problems appearing in the debugging.
