摘要

本文阐述了一种简单的声、光同时控制的路灯电路系统的制作。声、光同时控制的路灯电路，其功能为能够自动控制白天开关、夜晚亮灯、人走灯灭。具有灵敏、低耗、性能稳定、使用寿命长、节能等多种特点。本文选择了声敏传感器、光敏传感器作为基本元件，以AT89C2051单片机为核心，采用串行A/D对声音信号的采集。综合了声、光和延时控制、工作稳定、节电并可延长灯泡寿命。光敏传感器,声控传感器两种传感器形成了声控、光控两种控制的电路。利用布局和布线规则完成了电路板的制作。实现了电子开关的两种控制，实验结果实现了灯的控制。

研制中应用了过零启动技术，开关工作在频繁的开关状态时不易损坏可控硅。本系统中还加入了看门狗电路，在工作的过程中可以起到抗干扰的作用，大大的加强了系统的可靠性及实用性。

本设计是由电源电路、声控电路、光控电路和延时控制电路组成。电源电路由照明灯、整流二极管VD4～VD7 、电阻器R10、稳压二极管VS和滤波电容器C4组成。声控电路由压电陶瓷片BC、非门集成电路IC（D1～D6）内部的D1、D2、电阻器R1～R3和电容器C1组成。光控电路由光敏二极管VD1、IC内部的D3、D4和电阻器R9等组成。延时控制电路由电容器C2、C3、电阻器R4～R8、IC内部的D5、D6、晶体管V和晶闸管VT组成。交流220V电压经EL限流、VD4～VD7整流、R10降压、VS稳压及C4滤波后，为IC提供9V直流电压。

Abstract

This paper describes the production of a street circuit simple, light and sound control. Sound, light and lamp circuit control, its function is to control the switch during the day, night lighting, people walk lamp. Sensitive, low consumption, stable performance, long service life, energy saving and other features. This research chose acoustic sensors, light sensors as a basic element, use AT89C2051 microcontroller as the core, the serial A/D for voice signal acquisition. Combination of sound, light and delay control, stable work, energy saving and prolonging the service life of the bulb. Photosensitive sensor, acoustic sensor two sensor form the circuit voice, light two kinds of control. The layout and routing rules to complete the circuit board production. The two control electronic switch, the experimental results achieved control lamp.

Study of the application of the start of the technology, the switch is not easy to damage when in a state of frequent switching thyristor. This system also joined the watchdog circuit, in the process of work can play a role of anti-interference, greatly enhanced the reliability and practicability of the system.

This design is from the power circuit, voice circuit, light control circuit and delay control circuit. Power circuit from the lights, the rectifier diode VD4 ~ VD7, resistor R10, Zener diode VS and filter capacitor C4. A voice circuit of a piezoelectric ceramic BC, door integrated circuit IC (D1 ~ D6) inside the D1, D2, resistors R1 ~ R3 and capacitor C1. By the photodiode light control circuit VD1, IC internal D3, D4 and resistor R9 and other components. Delay control circuit by the capacitor C2, C3, resistor R4 ~ R8, IC internal D5, D6, transistors and thyristors VT V components. AC 220V voltage by EL limiting, after VD4 ~ VD7 rectified, R10 buck, VS regulator and C4 filter for IC provides 9V DC voltage.
