单片机晶振的作用

　　单片机晶振的作用是为系统提供基本的时钟信号。通常一个系统共用一个晶振，便于各部分保持同步。有些通讯系统的基频和射频使用不同的晶振，而通过电子调整频率的方法保持同步。　　晶振通常与锁相环电路配合使用，以提供系统所需的时钟频率。如果不同子系统需要不同频率的时钟信号，可以用与同一个晶振相连的不同锁相环来提供。　　在通常工作条件下，普通的晶振频率绝对精度可达百万分之五十。高级的精度更高。有些晶振...[详细]

　　O 引言　　随着电力电子技术的发展，稳定、可靠、低EMI成为对辅助电源最基本的要求。本文详细介绍了一种多路输出，而且相互独立的新型辅助电源的设计方法。　　设计采用AC/DC-AC/DC的变换方案。不控整流后的直流电压经过半桥变换电路逆变后，由高频变压器隔离降压，最后通过整流输出直流电压。为了满足对辅助电源的要求，系统主要由基于半桥LLC的谐振变换器，交流母线和全波整流组成。主电路采...[详细]
基于LIN总线和MAX6675温度传感器改善车辆制动性能

1、引言国内的大型、重型车辆普遍采用鼓式刹车装置，每年重型车辆在山路下坡行驶时因制动失灵造成的事故频发，刹车鼓温度过热导致制动器的散热不能满足要求是导致制动失灵的主要因素，提高重型车辆制动性能的最佳方案就是加装ABS，尽管国家已发布标准GB7258、GB12676来规定客车和货车必须安装符合要求的防抱死制动装置，以此来增强道路行驶的安全性。但实际配备情况很不理想，因为鼓式刹车换成盘式刹车、配备...[详细]
基于STM32 HID例程生成不小于64字节传输的移植过程

前言本文简单介绍如何应用ST USB HID(MOUSE)例程生成一个可以输入和输出任何长度小于等于64字节的移植过程。问题描述： HID的在USB的运用中是非常广泛的，但是很多应用并不是简单的鼠标或者键盘操作，而是客户自定义的一些应用，所以REPORT的定义往往跟鼠标或者键盘并不相同，因而客户常常基于ST的HID的例程进行修改。那么如何基于我们的例程生成一个可以输入输出任何长度小于等于64...[详细]

数字使智能视频监控超越传统系统

　　模拟系统构成了目前绝大部分视频安全系统，但是这些基于传统TV线缆技术的系统具有很多缺点：建设与维护可提供连接的宽带线缆基础设施耗资巨大；依靠人力监视多个摄像头来检测可疑活动会耗费大量人能监控系统能够高效运行至少5种算力，而且由于人为错误还会造成假警报和降低安全性；最重要的是，发生违反安全的行为和发现这种行为的间隔往往太长，因而无法预防犯罪，甚至也无法逮住不法分子。　　毫不夸张地说，模拟视...[详细]
产生双极性输出的无变压器 DC/DC 变换器

要从单个正极性输入产生双极性（正和负）输出的常见方法是采用变压器。虽然这种设计比较简单，但变压器本身会带来体积问题。把一个变压器装入一台要求减小电路占用面积和高度的设备中，这是具有挑战性的。图 1 所示电路可以从由3V "10V 输入产生 %26;#177;5V 输出，适用于没有地方安装变压器的设备。该电路所用的一种结构，能在 DC/DC 变换器处于关机模式时切断两个输出，这样就使处于关机（待机）...[详细]
