音乐喷泉控制系统设计
音乐喷泉控制系统设计摘要随着人们生活水平的提高和建立绿色城市的向往，音乐喷泉以其独特的魅力和特殊的功能，愈来愈成为休闲娱乐产业中的一项重要产品,音乐喷泉的兴建也越来越多。
根据目前音乐喷泉的发展现状，介绍了一个以AT89C51单片机为核心的小型音乐喷泉控制系统。
给出了一个简洁的单片机控制电路，分析了输出地址，描述了不同类型的输出电路和输入电路；介绍了从特定构造的喷池中获得决定喷池动作的喷池数据的原理；给出了主程序框图和看门狗子程序。
采用程序控制或人工按键控制电磁阀来控制花型。
音频信号还影响灯光色彩和灯光光线明暗的变化。
从而使灯光色彩、灯光的闪烁和喷泉水姿随音乐节奏而变化。

The flower shapes are controlled by program controlling or man-made keystroke controlling electromagnetic valves. The color、the light and shade of ray are changed by musical signals. So that the color、the light and shade of ray、the spring form is changed with music’s rhythm when m usic is played．Key Words:music fountain；SCM；SCM control；data of fountain pool；watchdog program目录摘要 (1)ABSTRACT (2)1 绪论 (5)1.1引言 (5)1.2小型音乐喷泉的发展现状 (5)1.3本文主要研究内容 (6)2 喷泉硬件设计 (7)2.1鱼缸设计 (7)2.2造型方案设计 (7)2.3花型及喷头的选择 (7)2.4喷泉照明灯具的选择 (10)2.5水泵和电机的选择 (10)3 喷泉控制系统硬件设计 (11)3.1控制系统硬件总体设计方案 (11)3.2单片机电路 (11)3.3输出电路 (13)3.4输入电路 (13)3.5潜水泵调速硬件方案设计 (14)3.6灯光硬件方案设计 (14)3.7电磁阀硬件方案设计 (15)3.8解决系统时间滞后硬件电路设计 (16)4 喷泉控制系统软件设计 (17)4.1喷池数据 (17)4.2主程序框图 (18)4.3控制潜水泵软件设计模块 (19)4.3.1 潜水泵开关调速的原理 (20)4.3.2潜水泵开关调速的软件设计 (20)4.4控制电磁阀软件设计模块 (21)4.5歌曲存储模块 (22)4.5.1音频脉冲的产生 (22)4.5.2音乐程序 (24)4.6灯光控制模块 (26)4.7看门狗子程序 (27)4.8实验仿真 (27)结论 (29)致谢 (30)参考文献 (31)第一章绪论1 绪论1.1引言随着人们生活水平的提高，人们对环境的要求越来越高,城市环境建设日益为人们所重视。

直流电机无级调速电路(完整篇)
直流电机无级调速电路/content/12/0330/23/7988683_199474671.shtml成品直流电机无级调速电路板很贵，我在维修一台包装机时得到一块直流电机调速板，经测绘并制作成功，现奉献给大家。
这块电路板电路简单，成本不高，制作容易，电路作简单分析：220V交流电经变压器T降压，P2整流，V5稳压得到9V直流电压，为四运放集成芯片LM324提供工作电源。
P1整流输出是提供直流电机励磁电源。
P4整流由可控硅控制得到0－200V的直流，接电机电枢，实现电机无级调速。
R1，C2是阻容元件，保护V1可控硅。
R3是串在电枢电路中作电流取样，当电机过载时，R3上电压增大，经D1整流，C3稳压，W1调节后进入LM324的12脚，与13脚比较从14脚输出到1脚，触发V7可控硅，D4 LED红色发光管亮，6脚电压拉高使V1可控硅不能触发，保护电机。
电机过载电流大小由W1调节。
市电过零检测，移相控制是由R5、R6降压，P3整流，经4N35隔离得到一个脉动直流进入14脚，从8脚到5脚输出是脉冲波，调节W2电位器即调节6脚的电压大小，可以改变脉冲的宽度，脉冲的中心与交流电过零时刻重合，使得双向可控硅很好地过零导通，D4是过载指示，D3是工作指示，W2是电机速度无级调节电位器。
电路制作好后只要元件合格，不用调整就可使用。
我从100W－1000W电机都试过，运行可靠，调节方便，性能优良。
12V直流电机高转矩电子调速器直流电机在一些应用中需要随时具有高转矩输出能力，无论它是处于低速还是高速运转。
例如钻孔、打磨、掘进等应用条件下，电机必需具备高低压运转的最大力矩输出。
显然，常用的线性降压调速无法达到这一要求，因为电机空载与加载状态其转速并不与工作电压成正比，若空载即需低速运转则加载后往往无法工作。
这里介绍一种专为大范围转矩变化的直流电机调速而设计的电路，它根据电机的工作电流变化来判断其加载状态，并由此对电机转速作出自动调整。

双向可控硅及其触发电路
双向可控硅及其触发电路双向可控硅是一种功率半导体器件，也称双向晶闸管，在单片机控制系统中，可作为功率驱动器件，由于双向可控硅没有反向耐压问题，控制电路简单，因此特别适合做交流无触点开关使用。
双向可控硅接通的一般都是一些功率较大的用电器，且连接在强电网络中，其触发电路的抗干扰问题很重要，通常都是通过光电耦合器将单片机控制系统中的触发信号加载到可控硅的控制极。
为减小驱动功率和可控硅触发时产生的干扰，交流电路双向可控硅的触发常采用过零触发电路。
〔过零触发是指在电压为零或零附近的瞬间接通，由于采用过零触发，因此需要正弦交流电过零检测电路〕双向可控硅分为三象限、四象限可控硅，四象限可控硅其导通条件如下列图：总的来说导通的条件就是：G极与T1之间存在一个足够的电压时并能够提供足够的导通电流就可以使可控硅导通，这个电压可以是正、负，和T1、T2之间的电流方向也没有关系。
因为双向可控硅可以双向导通，所以没有正极负极，但是有T1、T2之分再看看BT134-600E的简介：〔飞利浦公司的，双向四象限可控硅，最大电流4A〕推荐电路：为了提高效率，使触发脉冲与交流电压同步，要求每隔半个交流电的周期输出一个触发脉冲，且触发脉冲电压应大于4V ，脉冲宽度应大于20us.图中BT 为变压器，TPL521 - 2 为光电耦合器，起隔离作用。
当正弦交流电压接近零时，光电耦合器的两个发光二极管截止，三极管T1基极的偏置电阻电位使之导通，产生负脉冲信号，T1的输出端接到单片机80C51 的外部中断0 的输入引脚，以引起中断。
在中断效劳子程序中使用定时器累计移相时间，然后发出双向可控硅的同步触发信号。
过零检测电路A、B 两点电压输出波形如图2 所示。
过零触发电路电路如图3 所示，图中MOC3061 为光电耦合双向可控硅驱动器，也属于光电耦合器的一种，用来驱动双向可控硅BCR 并且起到隔离的作用，R6 为触发限流电阻，R7 为BCR 门极电阻，防止误触发，提高抗干扰能力。

常见电动车充电器的三种电路图
常见电动车充电器的三种电路图第一种：下图1为充电器的电路原理图，主要由整流滤波、高压开关、电压变换、恒流、恒压及充电控制等几部分组成。
其基本原理是充电器将输入的220V市电电压经整流滤波后转变为直流300V左右的电压，通过开关管的接通和关断，使300V直流电压变成受控制的交流电压，交流电压通过开关变压器耦合后在其二次侧产生低压交流电，低压交流电再通过二极管整流后输出直流充电电压。
图1开关管受电源厚模块的控制，4N35光耦合器将二次电压波动信号反馈给电源厚模块，从而达到稳定输出电压的目的。
使用开关电源作为充电器的好处是能有效的根据负载的大小控制输出，保护负载并节约能源。
第二种：以3842驱动场效应管的单管开关电源，配合358双运放来实现三阶段充电方式。
其电原理图和元件参数见图2。
图2工作原理：220v交流电经T0双向滤波抑制干扰，D1整流为脉动直流，再经C11滤波形成稳定的300V左右的直流电。
U1 为3842脉宽调制集成电路。
其5脚为电源负极，7脚为电源正极，6脚为脉冲输出直接驱动场效应管Q1(K1358) 3脚为最大电流限制，调整R25(2.5欧姆)的阻值可以调整充电器的最大电流。
2脚为电压反馈，可以调节充电器的输出电压。
4脚外接振荡电阻R1,和振荡电容C1。
T1为高频脉冲变压器，其作用有三个；第一是把高压脉冲将压为低压脉冲。
第二是起到隔离高压的作用，以防触电；第三是为uc3842提供工作电源。
D4为高频整流管（16A60V）C10为低压滤波电容,D5为12V稳压二极管，U3(431)为精密基准电压源，配合U2(光耦合器4N35) 起到自动调节充电器电压的作用。
调整w2(微调电阻)可以细调充电器的电压。
D10是电源指示灯。
D6为充电指示灯。
R27是电流取样电阻（0.1欧姆，5w）改变W1的阻值可以调整充电器转浮充的拐点电流（200－300 mA）通电开始时，C11上有300v左右电压。
此电压一路经T1加载到Q1。

电动车48V充电器维修经验
电动车48V充电器维修经验我们目前用的电动车充电器大部分都是脉冲式充电器。
就目前来说，以UC3842为主控芯片的充电器还是占绝大多数，当然也有不少是以TL494为主控芯片的充电器，对于采用这种芯片的充电器本文不做阐述（因这两种充电器的维修基本上是大同小异的）。
这类充电器的原理与开关电源的原理是基本相同的220V的交流电经交流滤波电路滤除外来的杂波信号(同时也防止电源本身产生的高频杂波对电网的干扰),再经二极管桥式整流电路和滤波电路，整流滤波后得到约300V的直流电，送给功率变换电路进行功率转换。
功率变换电路中的开关功率管（IGBT）就在脉冲宽度调制控制器（UC3842）输出的脉冲控制信号驱动下，工作在“开”“关”状态，从而将300V直流电切换成宽度可调的高频脉冲电压。
把高频脉冲电压送给高频脉冲变压器，其次级就会感应出一定的高频脉冲交流电，并送给高频整流滤波电路进行整流，滤波；最后输出一个很平滑的直流电，供给蓄电池充电。
由于蓄电池刚开始充电时和充过一段时间后，蓄电池的容量和端电压均不一样，这就由充电器内部取样电路将取样信号通过光电耦合器（PC817）送入控制电路，经过脉宽调制芯片（UC3842）内部调制，由控制电路的输出端将变宽或变窄的驱动脉冲送到开关功率管的栅极，使变换电路产生的高频脉冲方波也随之变宽或变窄，使蓄电池的充电分别进入：恒流充电，恒压充电和浮充充电这三个充电阶段。
一、故障及处理方法1. 充电器由KA3842和HY358双运算放大器组成,故障为无48V电压输出,拆开外壳检查发现63V470uf电容爆液,更换后,接着检查有无损坏的元器件和短路,经仔细检查后,通电测试,输出正常,移动电路板后,又测电压变为67V,与实际输出过高,有2秒钟后,63V电容微微冒烟,温度升高,眼看爆炸,立即断电.经查发现TL431一脚虚焊,造成稳压失控,烧坏63V电容.2.拆开充电器,由LM324 贴片IC KA3842组成电路.保险熔断,不敢通电测试,经查,有两只整流管IN5399 IN5398击穿,开关场效应管GFP8N60两脚击穿,IN5399用RL207代换,开关管8N60用PHX7NQ60E代换.然后,保险处接上灯泡,通电灯泡一亮即灭,测量电压正常55.2V,取下灯泡接上保险,给电动车充电,刚接上不到10秒钟,听到叭的一声,保险又烧断.经查,开关管,又击穿了,测得KA3842第5脚接地与第6脚短路.更换K3842,接上灯泡测试充电,灯泡,以1HZ的频率一闪一闪的,充电器也停了又启,启了又停.取下灯泡,接上保险,一直正常充电,问题排除.3. 48V 1.8A充电器保险完好,测开关管,电容正常,通电测试,红绿灯同时有频率的一闪一闪,刚启动输出电压为54.5正常,又等一会儿,电压慢慢下降30-36V之间.测TL431,光藕正常,检查其它电阻,都正常阻值.依次更换,开关管8N60,TL431,光藕,63V电容,测得400V电容有320V电压,最后更换PFC电感,电容,均无正常电压输出.并且仔细测量各个限流电阻,与实际阻值相差多的,也更换.还是不能解决.最后从电脑主板上拆下LM324更换后,通电测试电压输出正常,红绿灯显示正常,但没有进行下一步带负载充电测试.4. 拆开后发现烧毁不少地方：进线电路板铜箔烧毁2处，14007整流二极管坏了4个，贴片电阻270坏。

IMPORTANT NOTICE
Texas Instruments (TI) reserves the right to make changes to its products or to discontinue any semiconductor product or service without notice, and advises its customers to obtain the latest version of relevant information to verify, before placing orders, that the information being relied on is current and complete.
TI warrants performance of its semiconductor products and related software to the specifications applicable at the time of sale in accordance with TI’s standard warranty. Testing and other quality control techniques are utilized to the extent TI deems necessary to support this warranty. Specific testing of all parameters of each device is not necessarily performed, except those mandated by government requirements.
Certain applications using semiconductor products may involve potential risks of death, personal injury, or severe property or environmental damage (“Critical Applications”).
TI SEMICONDUCTOR PRODUCTS ARE NOT DESIGNED, INTENDED, AUTHORIZED, OR WARRANTED TO BE SUITABLE FOR USE IN LIFE-SUPPORT APPLICATIONS, DEVICES OR SYSTEMS OR OTHER CRITICAL APPLICATIONS.
Inclusion of TI products in such applications is understood to be fully at the risk of the customer. Use of TI products in such applications requires the written approval of an appropriate TI officer. Questions concerning potential risk applications should be directed to TI through a local SC sales office.
In order to minimize risks associated with the customer’s applications, adequate design and operating safeguards should be provided by the customer to minimize inherent or procedural hazards.
TI assumes no liability for applications assistance, customer product design, software performance, or infringement of patents or services described herein. Nor does TI warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or other intellectual property right of TI covering or relating to any combination, machine, or process in which such semiconductor products or services might be or are used.
