天津市盛群杯大学生电子设计竞赛一等奖该作品针对校园和其它公共场合浪费用电现象,以HT46R24单片机为控制核心,通过多种传感器采集室内光线、人数分布等信息,可对照明设备实现智能控制。采用以硅光电池为核心构成的光电传感器测量光照强度,根据光电池短路电流在较大范围内与光照强度成线性关系的特点,可实现连续的光强模拟量输出和较高的精度。光强度信息送至单片机,并根据外界光照强度自动调节电灯亮度,从而实现照明环境的自动调节,可有效改善照明质量。
Tianjin Shengqun Cup first prize for college students electronic design contest The works against the campus and other public places waste of electricity phenomenon to HT46R24 microcontroller as the control center through a variety of sensors to collect indoor lighting, the number of people and other information distribution, lighting equipment can be achieved intelligent control. The photoelectric sensor based on silicon photovoltaic cell is used to measure the light intensity. According to the characteristic that the photocurrent short-circuit current is linear with the light intensity in a wide range, continuous light intensity analog output and high precision can be realized. Light intensity information sent to the microcontroller, and automatically adjust the light intensity according to the external light intensity, so as to achieve automatic adjustment of the lighting environment, which can effectively improve the lighting quality.
