重庆邮电大学移通学院本科毕业设计（论文）ABSTRACTThis topic for the classroom lighting control,analyzed the classroom light intelligent controlprinciple and realization method of the classroom light intelligent control system is proposed basedon single-chip microcomputer,and on this basis to develop the intelligent control system hardwaremodules and software part accordingly.The system takes the AT89S51 microcontroller as the core part of the control module,andUSES the pyrolysis infrared human sensor to detect the existence of the human body.According tothe reasonable ambient light conditions,through the existing signal to the human body and theambient light signal identification and judgment,the completion of the classroom lightingintelligent control,to avoid the classroom a large amount of waste of electricity.The system alsohas alarm function;Also adopted soft/hardware anti-jamming measures,such as "watchdog"thewhole software design received by initialization module,keyboard module,interrupt handlingmodule,data display module and timing output module of five modules.The program part of the system is written in C language,with modular structure design,clearstructure,good versatility,and easy to improve and expand.The system has small volume,convenient control,high reliability,the pertinence,high cost performance,can meet therequirements of all kinds of colleges and universities for the classroom lighting control,greatly toachieve energy saving purpose.[Key words]Intelligent controller Pyrolytic infrared sensor Single chip microcomputer
