房间自动照明控制系统设计毕业设计论文

The paper expatiates on the designing theories and implementation method of the control system for lighting. Taking the designing process as mainline, it describes the process of designing from two respects—hardware and software. Inanotherword, the paper describes the process from the method of circuit designing to the software technology of realizing the demanded functions. The controller of the control system for lighting is based on AT89C51 single-chip microcomputer. The system can do many jobs, such as controlling and display. The paperdescribesthe designing process of the circuit at length, including:keyboard and LCD displaycircuit, control circuit of lighting, watchdog circuit, etc. The designing of software mainlyincludesthe several programming, such as lamplight controlling,keyboardscanning and LCD displaying. The function is thatthroughHuman-release thermal infrared,Phototransistorand AT89C51 single-chip microcomputer sends orders toturnon lighting, turn off lighting,regulatebrightness of room, etc.
