STC12C5A60S2单片机小型太阳能发电系统设计+电路图

摘要这篇文章主要对小型太阳能发电系统进行学习和研究。首先对太阳能发电系统的构成进行了简要的概述，然后进一步揭示各个部分的工作原理。接下来又针对各个部分的组成，分别对元器件进行学习，介绍其参数性能以及所起到的功能作用。本文主要采取硬件和软件相结合的办法，去设计并且制作小型太阳能发电系统。在硬件设计方面：通过晶体硅太阳能板去吸收太阳光，然后把太阳的辐射能转换为化学能存储在蓄电池之中。设计了DC/DC变换电路，蓄电池通过直流降压型变换电路，把直流电压分别变换成12V,5V,3。3V电压输出出来。设计了逆变器，通过逆变器的作用，把12V直流电逆变成220V交流电。在控制电路中，选用了STC12C5A60S2型号的单片机作为控制器，通过模拟/数字转换采样后，液晶显示屏上可以实时地检测并且显示出输出直流端的电压、电流、功率和电池电量。在软件设计方面：利用C语言代码来编写程序。程序采集了四个按键的状态，以显示出设定值和采集值之间的切换，通过按键实现数字的相加减。从而通过程序的控制，实现显示屏的显示模式、报警输出、以及采样控制等，完成控制测量系统的设计。最后加以组合，最终实现整个系统的功能。78741

Title Design And Research Of A Small Solar Power Generation System

Abstract This article mainly focus on the study and research of small-scale solar power generation system。Firstly,solar power systems are briefly outlined,and then it reveals the working principle of each part。According to the composition of each part,it introduces the function and parameters of the role。 This paper mainly adopts with the combination of hardware and software, to design and make small solar power generation system。 In the aspect of hardware design: the crystal silicon solar panels absorb sunlight, then turn solar radiation energy into chemical energy stored in the battery。 In aspect Of DC/DC transform circuit design, the battery converter circuit through the DC buck , the DC voltage are transformed into 12V, 5V, 3。3V。Designing the inverter to convert the DC 12V into AC 220V。In the control circuit,choose the microcontroller STC89C52 as the controller, through the A/D simulation/sampling ,LCD screen can real-time detect and display the DC voltage,current,power and battery power。In the aspect of software design: using C language to write the program code。Collecting four key state in order to show the set value and collection value between the switch, to achieve digital addition and subtraction through the keys,to achieve the display mode,alarm output and sampling control,completeing the design of measurement and control system。 The last work is to combine every part to realize the function of the whole system。
