USB 3.1 概述

不仅仅是速度提升 USB3.1新规格详解在今年的夏秋交汇之际，USB与SATA两个接口规格都发布了新方案。

首先是7月31日USB应用者论坛USB-IF发布了USB 3.1，接连着就是 8月8日SATA标准化团体SATA-IO释出的SATA Revision 3.2。

另英特尔今年将会全力推广传输速率达到20Gbps的Thunderbolt 2 关于USB3.1，从至今为止的新闻等等渠道了解到，速度将提升至理论10Gb/s，相比USB3.0规格提高了一倍以上。

然而USB3.1带给我们的不止是速度的提升，虽然USB3.1标准刚刚发布，距离应用还有一段时间，不过笔者在ascii.jp上已经看到了较为详细的介绍，今天笔者将该文编译下来，与国内读者分享。

USB2.0的高速版本USB3.0将线缆与接口都改为蓝色，那么USB3.1又将带给我们什么呢。

USB 3.1进一步提升传输速率在看到这篇文章之前，笔者也想不到USB 3.0标准发布已经有5年之久了。

可能由于Intel和微软方面原生支持的较晚，使得USB 3.0虽然众所周知，但受益者并不是那么广泛。

在通过高速U盘、搭载SSD的移动硬盘等使得外接存储设备迅猛提速的今天，不知不觉USB3.0的接口速度也已经到达极限了，对于标准制定者而言，是时候推出更新了。

看到这种需求，今年１月份，USB-IF(USB Implementers Forum，USB实施者论坛)中，尤其是USB 3.0开发推进小组「USB 3.0 Promoter group」发表称，下一代的USB传输规格定为10Gb/s，推出仅仅是时间问题。

USB 3.1 由于刚刚发布，各种不明确的地方还很多，不过还是在这里向大家说明一下与USB 3.0的不同之处。

首先是LOGO的改变，下面左图为USB 3.0，右图为从USB-IF的新闻稿中截取的USB 3.1 LOGO。

由于两LOGO来源不同，请忽视颜色差异，这样一来两者没有多大的区别，需要说明的「SUPERSPEED+」这个名称。

usb 3.1 带动硬盘的原理

USB3.1是一种高速的数据传输接口，它能够提供比USB2.0更高的数据传输速度。

它是一种新型的USB接口标准，能够实现更快的数据传输速度，因此被广泛应用于计算机和外部设备的连接。

硬盘是一种存储设备，它可以将数据存储在硬质材料中，以便于长期保存和读取。

本文将介绍usb3.1带动硬盘的原理，包括硬盘的工作原理、USB3.1接口的工作原理以及两者结合的工作过程。

一、硬盘的工作原理硬盘通常由一个或多个磁盘片和一个硬盘驱动器组成。

硬盘驱动器由机械和电子部件组成，包括旋转轴、磁盘表面、控制电路和电机等。

当硬盘驱动器接收到写入或读取指令时，它会读取或写入数据到磁盘表面，并通过控制电路进行处理和传输。

硬盘的读写速度受到多种因素的影响，包括磁盘转速、磁头移动速度、数据缓存大小等。

二、USB3.1接口的工作原理USB3.1接口是一种高速数据传输接口，它能够实现高达5Gbps的数据传输速度。

USB3.1接口分为两种类型：USB-A型和USB-C型。

USB 接口由一个或多个USB针脚组成，用于传输数据和控制信号。

USB3.1接口采用了新的电缆和针脚设计，以便于实现更高的数据传输速度和更小的尺寸。

USB3.1接口的工作原理主要包括以下几个方面：1.数据传输：USB3.1接口通过电子信号传输数据，当计算机或外部设备需要传输数据时，它们会通过USB电缆将数据发送到另一个设备。

2.电源传输：USB3.1接口还可以传输电源，以便于外部设备能够正常工作。

3.协议：USB3.1接口使用了一种新的协议，称为USBPowerDelivery（USBPD），该协议能够实现更高的数据传输速度和更长的电源传输距离。

当USB3.1接口与硬盘连接时，它可以通过高速数据传输来带动硬盘的工作。

具体来说，USB3.1接口将数据发送到硬盘驱动器，驱动器读取或写入数据到磁盘表面，从而实现数据的存储和读取。

这个过程涉及到以下几个步骤：1.数据传输：当计算机或外部设备需要传输数据时，它们会将数据发送到USB3.1接口。

USB3.1,你需要了解这几点

USB3.1，你需要了解这几点USB3.1的Type-A、Type-C、Type-B接口（从左到右）从1996年出现算起，USB接口已经成为我们最常用的一种接口。

经过不断的标准更新，USB从1.0进化到USB3.1，可谓历久弥新。

而在最近，苹果这家特别喜欢创新的企业，在新MacBook上什么接口也没有，就带了一个USB3.1 Type-C 接口。

既然都说到了Type-C，那么还有其他规格吗。

下面就从新手角度，聊聊USB3.1规格的小故事吧。

Type-C最大的好处是？真正吸引大家关注的，除了是USB3.1将速度在USB3.0的基础上又提升了一倍达到10Gbps，还有USB3.1新增的Type-C 接口界面，它在外观上与以往的Micro USB接口界面相似，但实际上完全无法兼容。

Type-C也是以迷你的造型来适应手机、智能穿戴设备的迷你化需求，但Type-C吸收了苹果Lightning连接器的灵感，正反向都可插入设备。

这就改变USB常年被大家诟病的只能单向插入，摸黑难于操作的“反人类设计”形象。

USB Type-C (左）、苹果Lightning 和micro USB (右)接口比较Type-A和Type-B有Type-C接口类型，USB3.1自然也有Type-A和Type-B。

实际上这两种接口界面延续了USB3.0标准中Standard-A 与Micro-B的造型与尺寸，这也让它们无法享受正方向皆可插入的“福利”。

Type-A更多应用在电脑上，而Type-B则用在追求轻薄，但对供电有较高要求的设备，如移动硬盘，移动光驱，大功率移动设备等等。

另外还要提到“方口”Standard-B接口，这种接口多用在大型外设上，比如打印机。

不过这种接口实在太厚了，用着并不方便，使用的设备也较少，所以，在USB3.1规范中，这种接口被取消了。

当然，你也甭担心使用这一端口的设备今后无法使用了，毕竟USB3.1还是向下兼容的。

USB-CQM1-CIF02驱动安装说明

USB-CQM1-CIF02编程电缆驱动程序安装说明概述USB编程电缆是通过将电脑的USB口模拟成传统的串行口（通常为COM3），从而使编程软件OMRON CPT通过USB-CQM1-CIF02编程电缆与CQM1/CPM1A/CPM2A PLC进行通信。

功能●支持的操作系统Windows XP/ Windows2000●兼容USB V1.1 V2.0●波特率：300bps～1Mbps自动适应●每台PC只支持一根USB编程电缆系统要求请在使用USB编程电缆之前确认你的电脑是IBM PC兼容型并具备以下最低系统要求：●Intel兼容586DX4-100MHz中央处理器或更高●一个标准的USB接口（4-pin A型插座）驱动程序的安装驱动程序的安装非常简单，只需按提示进行即可，以Windows XP为例，按以下步骤进行：1、打开电脑主机，插入驱动程序光盘。

2、将USB-CQM1-CIF02电缆插入电脑的USB接口，Windows将检测到设备并运行添加新硬件向导帮助你设置新设备，并单击下一步继续。

如果Windows没有提示找到新硬件，那么在设备管理器的硬件列表中，展开“通用串行总线控制器”，选择带问号的USB设备，单击鼠标右键并运行更新驱动程序。

3、Windows将检测到安装信息，并出现如下没有通过Windows徽标测试的信息框，单击“仍然继续”。

4、继续安装，让Windows拷贝驱动程序文件到你的硬盘。

5、当Windows显示完成找到新硬件向导，单击“完成”结束安装。

6、安装完成后，请确认在Windows的“开始\设置\控制面板\系统\硬件\设备管理器”菜单的“端口（COM和LPT）”展开条目中出现“ProlificUSB-to-Serial Comm（COMx）”，这个COMx就是USB编程电缆使用的COM口号，该端口号与电脑有关，一般为COM3或COM4，以后每次使用只要插入编程电缆就会出现该COM口，你只需在编程软件或通信软件等应用软件中选中该COM口号即可通信。

飞行堡垒G11的USB3.1传输速率

飞行堡垒G11的USB3.1传输速率
说明一下，G11飞行堡垒的USB3.1接口并不是type-c型接口，所以它可以向下兼容USB3.0和USB2.0。

好嘞，让我们来看看它到底有多快！~
为了看看这接口的性能，我还特意买了一块USB3.1接口的U盘。

U盘的格式通通为exFAT，NTFS伤U盘这个大家都知道的，另外FAT32只能存4GB 以下的问题，所以还是exFAT吧。

测试文件就是个电影，大概1个多GB吧~
这个是USB3.1的读取速度，可以理解成U盘往电脑里拷贝东西
这个是USB3.0的速度。

为什么我不测试从电脑往U盘里拷贝的速度呢？
因为我的这个U盘号称100MB/s传输，但实际上单指的是读取速度……写入速度只有可怜的15MB/s。

但不管怎么说，我们还是看到G11上的USB3.1接口，在传输速度上又有了进一步提升，而且成效显著，每秒40M的速率提升还是很不错的。

另外，想真正感受下USB3.1接口性能的，买设备的时候除了要看读取速度，还要看下写入速度！！！。

When you connect to your network through the ethernet port of the dock, the computer's MAC address is typically not broadcast to the network, as your network only sees the MAC address of the docking station. However, the MAC Address Changer or Cloning software enables the USB-C dock to use MAC address spoofing of the connected Windows laptop rather than the MAC address of the dock itself. This ensures your network administrators have full visibility of each device on the network and can monitor and limit activity accordingly.

常用USB转串口芯片介绍

常用USB转串口芯片介绍常用USB转串口芯片介绍USB转串口是计算机与串行设备之间相互连接的方式。

使用串口通信协议，可以将计算机与各种设备连接起来，如调试器、机器人、嵌入式设备等。

USB转串口芯片则是用于将计算机的USB接口转为串口信号输出，实现计算机与串口设备的通讯。

下文将讨论常用的USB转串口芯片及其特点。

1. FTDI芯片FTDI（Future Technology Devices International）公司的FT232系列芯片是最常用的USB转串口芯片之一，在市场上具有较高的占有率和口碑。

FTDI的芯片采用USB2.0接口，支持全速和高速传输，通讯速率可达到12Mbps。

FT232系列芯片提供了专业的驱动程序，可以在Windows、Linux、MAC OS、Android 等多个操作系统下使用，兼容USB1.1和USB2.0接口。

此外，FTDI还提供了免费的开发工具、应用手册和API文档，可自定义串口输出格式和流控方式。

2. CP2102芯片CP2102芯片由Silicon Laboratories公司生产，是另一种常用的USB转串口芯片。

CP2102通过USB2.0接口，支持全速和高速传输，通讯速率最高可达1Mbps。

这种芯片具有低功耗、低成本、体积小、易于集成等特点。

CP2102还支持多种工作模式和流控方式，例如直接模式、流控模式、硬件流控等，可根据应用场景自行选择。

3. CH340芯片CH340芯片由中国北京朝晖公司研发生产，是国内一种比较流行的USB转串口芯片。

CH340通过USB1.1接口，传输速率最高可达115200bps，为节约成本采用了单片机内部RC振荡器，因此准确度相对较低。

不过，CH340的性价比非常高，价格便宜，需要的元器件也很少，很适合嵌入式开发、单片机下载等领域的用户。

4. PL2303芯片PL2303芯片是由Prolific Technology公司开发的USB转串口芯片。

USB-CQM1-CIF02编程电缆使用手册

USB-CQM1-CIF02编程电缆使用手册概述：USB-CQM1-CIF02编程电缆是通过电脑的USB口仿真成传统串口（俗称COM口），从而使用现有的各种编程软件、通信软件和监控软件等。

本电缆的工作电源取自USB端口，不再由PLC的编程口供电，转换盒上的发光二极管指示数据的收发状态，USB-CQM1-CIF02电缆适用于OMRON CPM1/CPM2/CPM1A/CPM2A/CQM1系列PLCUSB-CQM1-CIF02电缆外观：技术指标：●操作系统：Windows2000/Windows XP●支持编程软件版本：STEP7 Micro/WIN V3.2及以上版本●支持UART数据格式：数据位：8，停止位：1、2，校验位：odd/even/no parity●每台PC只支持一根USB编程电缆使用方法：1. USB-CQM1-CIF02编程电缆需要安装USB驱动程序才能使用，驱动程序包含在所附光盘上。

2. 驱动程序安装完成后，在Windows的设备管理器中将出现USB-CQM1-CIF02编程电缆对应的COM口号，只需在编程软件中选择该COM口号即可，其使用与串口编程电缆CQM1-CIF02完全相同。

3.平时使用时先把电缆插入电脑USB口，再把20针口插入PLC4.打开\资源管理器\查看COM口号, 方法为用鼠标单击\我的电脑\控制面板\管理工具\计算机管理\设备管理器\端口(COM和LPT) \ Prolific USB-to-Serial Comm（COMx）\ 这个COMx就是USB 编程电缆使用的COM口号5.打开编程软件设置好COM口就可通信注意：1．不可在关闭编程软件前插拔USB-CQM1-CIF02电缆，否则会不能通信。

如不小心已拔电缆，须关闭编程软件后，重复（使用方法）第3-5项。

或关闭电脑后重新开机。

2，通信长时间PLC仍无反应，须关闭电脑后重新开。
