智能台灯设计
摘要
设计制作了一种智能台灯,主要是以BISS0001和单片机组成的红外传感控制电路。其特点是在有人时且外界光强较弱时能自动开灯,无人时关灯,节约能源;且能纠正坐姿,防止近视。
单片机控制部分采用80C51单片机为核心,主要由热释电红外传感器,光敏电阻信号处理电路,提醒电路,灯光控制电路,故障报警电路等组成,软件选用汇编语言编程。单片机可将热释电红外传感器检测到的人体辐射红外信号及光强信号的模拟量转换成数字量。该系统灵活性强,易于操作,可靠性高,将会有更广阔的开发前景。

The Design of Smart Table Lamp
Abstract
Design a smart lamp, mainly infrared sensor control circuit posed of BISS0001 and SCM. Its characteristics are automatically turn on the lights when people and the outside light is weak, turn off the lights when no one, save energy; and can correct the posture, preventing myopia
MCU control part of the 80C51 microcontroller as the core, posed of the pyroelectric infrared sensor, photoresistor signal processing circuit, to remind the circuit, the lighting control circuit, the fault alarm ponents, software selection of assembly language programming. Single-chip analog of the pyroelectric infrared sensor detects the infrared signal of the human radiation and light intensity signals into digital. The system is flexible, easy operation, high reliability, there will be more broad prospects of development.
Key Words: energy conservation;to correct posture;BISS0001;80C51
