| 中文摘要: |
| 为了能使照度计显示照度的同时,将照度值所对应的感应电压值也显示出来,方便对光电探测器的工作状态进行实时监测,设计了基于单片机的模拟光照度计。对该光照度计的光电转换电路、放大滤波电路、A/D转换电路、显示电路以及报警电路进行了设计,搭建了硬件电路系统,做出了光照度计的实物,并完成了对实物的调试工作。实验证明,所设计的光照度计可有效显示感应电压值。 |

| In order to display the luxmeter of illumination and the induced voltage of illuminance, we design illuminometer based on a single chip microcomputer simulation, and the photoelectric conversion circuit, amplifier filtering circuit, A/D conversion circuit, display circuit and alarm circuit. The hardware circuit system is built. The debugging is completed. Experiments show that the system of illuminometer can display the induced voltage effectively. |
