节电照明电路的设计(任务书,开题报告,论文9000字)
摘要
为了节约用电,设计节电照明电路是非常有必要的,节电照明电路具有实用性强、成本低廉、安装简单便于操作,可以大范围的去应用等特点。本论文所阐述的节电照明电路是声光控节电照明电路。整个硬件电路由7部分组成,分别是话筒、声控电路、信号转换电路、光控电路、开关电路、延时电路和电源电路。话筒的作用主要是采集声音信号,它可以把声音信号转变为电信号,然后通过光控电路和开关电路来控制电路的工作状态。信号转换电路的主要作用就是把电信号转换为直流控制电压。延时电路是为了更加合理有效的利用资源而设计的,电源电路主要是采用桥式整流电路对交流电源的整流。可以使灯泡在有声音没有光照的环境下工作,其他环境下是不会工作的,从而可以节约大量电能。

The stanza electricity illuminates the design of electric circuit
ABSTRACT
In order to save electricity, energy-saving lighting circuit design is very necessary, energy-saving lighting circuit has a practical, low cost, easy to install easy to operate, can be applied to a wide range of characteristics. This thesis elaborated saving lighting circuits is sound and light control power-saving lighting circuit. The hardware circuit consists of seven parts, namely the microphone, the voice circuit, a signal conversion circuit, control circuit, a switching circuit, a delay circuit and power circuit. The main function is to collect the microphone sound signal, which can be the sound signals into electrical signals, and then through the light control circuit and the switching circuit to control the operation of the circuit condition. Signal conversion circuit's main role is to convert electrical signals to the DC control voltage. Delay circuit is provided to a more rational and efficient use of resources and design, the power supply circuit mainly used for the bridge rectifier circuit for rectifying AC power supply. You can make a voice no light bulb in the working environment, other circumstances will not work, so you can save a lot of electricity.
