说明书(三维立体式LED广告牌的制作及调试方法)
三维立体式LED广告牌制作及调试方法技术领域本发明属于一种广告牌制作及调试方法，具体地说就是三维立体式LED广告牌制作及调试方法。
背景技术LED广告是一种新媒体广告,是新媒体技术与室内外广告发布形式的完美结合。
LED广告是利用发光二极管拼成广告字样或者图片，通过控制半导体发光二极管的亮、灭来显示文字、图像，譬如我们平常在大街上看到的电子大屏幕广告或是一些路边带彩光的高亮的招牌。
与传统的广告牌相比LED广告牌具有寿命长、光效高、无辐射、可显示彩色和动态画面、显示内容更换方便、低功耗等优点。
但现行的LED广告牌也有明显的缺点：1、仅能显示二维平面，且具有视觉局限性。
目前使用的LED广告牌大多是由发光二极管组成的点阵块或直接用发光二极管组成一定长宽的显示屏，由于点阵块是平面的，组成的显示屏也只能是平面的，不能进行三维立体空间的显示。
发光二极管发光强度是方向的分布函数，称为发光角度，发光角度越小发光强度越大，不同的LED其发光角度不一样，但都有一个阈值，超过阈值时，其发光强度仅为最大发光强度的10%以下，因此不同角度视觉上的感受不同，存在视觉上的局限性。
2、成本高，控制电路复杂。
由于单个发光二极管或8×8的点阵块面积较小，要组成一定面积的显示屏，需要的发光二极管或8×8的点阵块数量就会很多，成本相对较高。
LED显示屏的显示原理是将要显示的二维平面内容（文字或图形）按行或列进行分解，转化成相应的控制电压信号，然后将这些控制电压信号按时间先后顺序分别传送到固定的位置，使发光二极管按电压信号的要求亮或灭，由于人眼的视觉惰性，只要控制好传送的行或列信息的时间，就能让人感觉显示的是一张完整的画面。
由于分解的行或列多，控制电路复杂。
3、功耗大。
相对传统的霓虹灯广告牌，LED广告牌具有显著的节能效果，但就LED广告牌本身来说，由于使用的发光二极管或8×8的点阵块的数量巨大，其实际功耗也很大。

二硬件电路设计照明灯灯系统的电路主要分为单片机数据处理模块、照明灯显示模块及电源模块等几个部分，结构框图如图2.1所示。
下面对电路分模块进行说明。
图2.1 系统框图2.1单片机数据处理模块AT89C51是一种带4K字节可编程可擦除只读存储器（FPEROM—Falsh Programmable and Erasable Read Only Memory）的低电压，高性能CMOS8位微处理器。
AT89C51采用ATMEL高密度非易失存储器制造技术制造，与工业标准的MCS-51指令集和输出管脚相兼容。
由于将多功能8位CPU和闪烁存储器组合在单个芯片中，ATMEL 的AT89C51是一种高效微控制器，AT89C51单片机为很多嵌入式控制系统提供了一种灵活性高且价廉的方案1．主要特性：·与MCS-51 兼容·4K字节可编程闪烁存储器寿命：1000写/擦循环数据保留时间：10年·全静态工作：0Hz-24Hz·三级程序存储器锁定·128*8位内部RAM·32可编程I/O 线 ·两个16位定时器/计数器 ·5个中断源 ·可编程串行通道 ·低功耗的闲置和掉电模式 ·片内振荡器和时钟电路图2.2 AT89C51引脚功能图 2．管脚功能说明，如图2.2所示3．振荡器电路：图2.3振荡电路图XTAL1和XTAL2分别为反向放大器的输 入和输出。
该反向放大器可以配置为片内振荡器，和片外振荡器两种。
本系统采用的是内部振荡方式，其外接晶振采用12MHz ，电容C1、C2采用30pF ，此时的机器周期的1us 。
时钟振荡电路如图2.3所示。
EA/VP 31X119X218RESET 9RD 17WR 16INT012INT113T014T115P101P112P123P134P145P156P167P178P0039P0138P0237P0336P0435P0534P0633P0732P2021P2122P2223P2324P2425P2526P2627P2728PSEN29ALE/P 30TXD 11RXD 10U18031C130p C230p12M4．复位电路单片机的复位靠外部电路实现，信号由RST (RESET)引脚输入，其复位电路由两种：一是上电复位，二是上电和手动电平复位（按键复位）。
本设计系统采用的上电复位，当接通电源后单片机立即复位。
单片机从PC 指针0000H 开始读程序。
其电路图如图2.4所示。
因晶振采用12MHz ，所以C1为10uF ，R1为8.1，R2为200。
图2.4 复位电路2.2 灯光显示模块灯光显示模块在整个系统中起一个显示作用，由74HC595、照明灯、晶闸管、光耦合组成，其电路框图如图2.5所示，74HC595的作用是串入并出，为光耦合送入信息，晶闸管在显示电路中起一个控制灯的作用，光耦合在电路中起保护隔离作用，使显示高压部分和控制部分分离，对单片机模块有一个保护作用，防止因电压过高烧毁单片机，使整个系统瘫痪，提高了整个系统适应恶劣环境的能力。
图2.5显示电路框图1.74HC59574HC595 为8位串入并出的移位寄存器，其引脚如图2.5所示，Q7～Q0为八位并行输出端；Q7’为级联输出端；DS 是串行数据输入端；MR 为数据清零端，低电平有效；OE 为片选端，低电平有效；SH_CP 引脚上升沿时数据寄存器的数据移位，ST_CP 引脚上升沿时移位寄存器的数据进入数据存储寄存器，下降沿时存储寄存器数据不变。
其中74HC595的DS 引脚接P3.0（RXD ），SH_CP 引脚接P3.1(TXD)做为移位时钟脉冲输入端，ST_CP 引脚接P3.3做为锁存器的时钟脉冲的输入端。
在电路中起一个串入并出的作用，这样可以节省电路接口，使电路连接简单。
图2.4 74HC595引脚功能图2.光电耦合器光耦合器（optical coupler，英文缩写为OC）亦称光电隔离器或光电耦合器，简称光耦。
它是以光为媒介来传输电信号的器件，通常把发光器（红外线发光二极管LED）与受光器（光敏半导体管）封装在同一管壳内。
当输入端加电信号时发光器发出光线，受光器接受光线之后就产生光电流，从输出端流出，从而实现了“电—光—电”转换。
以光为媒介把输入端信号耦合到输出端的光电耦合器，由于具有输出和输入之间绝缘，单向传输信号等优点，在数字电路上获得广泛的应用。
在本电路中的作用是通过光耦来隔离强电和弱电部分，对单片机部分有保护作用。
设计中采用TLP521-4光耦合器，其具有四路输入输出的功能，工作电压在+5V,其性能稳定各个功能引脚图入图2.6所示图2.6TLP521-4引脚功能图3.显示模块的总电路图，如图2.7所示图2.7显示模块电路图2.3稳压电源1. 电源电路因为单片机工作电源为+5V ，且底层电路功耗很小。
