Description

具有OTG功能的可移动存储装置Removable storage device with OTG function 技术领域Technical field
本发明涉及存储技术领域,具体而言,涉及一种具有OTG功能的可移动存储装置。The present invention relates to the field of storage technologies, and in particular to a removable storage device having an OTG function.
背景技术Background technique
在现有的可移动存储装置中,最常见的是U盘。U盘,全称USB闪存驱动器,英文名为USB flash disk,是一种使用USB接口的无需物理驱动器的微型高容量移动存储产品。Among the existing removable storage devices, the most common one is a USB flash drive. U disk, the full name of the USB flash drive, the English name is USB flash disk, is a micro-high-capacity mobile storage product that uses a USB interface without physical drives.
USB的全称是Universal Serial Bus(通用串行总线),是由英特尔(Intel)、康柏、国际商业机器公司(International Business Machines Corporation,简称IBM)、微软(Microsoft)等多家公司于1994年联合提出的一种数据传输总线,用于规范电脑与外部设备间的数据连接和通讯。The full name of USB is Universal Serial Bus, which was jointly established by Intel, Compaq, International Business Machines Corporation (IBM), Microsoft (Microsoft) and other companies in 1994. A data transmission bus is proposed for standardizing data connection and communication between a computer and an external device.
USB技术的发展,使得PC(Personal Computer,个人计算机)和周边设备能够通过USB总线将各种进行数据传输的设备简单的连接在一起,作为PC的周边,在PC的控制下进行数据交换。但这种方便的交换方式,一旦离开了PC,各设备间无法利用USB口进行操作,因为没有一个从属设备能够充当PC一样的主设备(host)。With the development of USB technology, PCs (Personal Computers) and peripheral devices can easily connect various devices for data transmission through the USB bus, and exchange data under the control of the PC as the periphery of the PC. However, this convenient exchange method, once left the PC, can not operate with the USB port between the devices, because no slave device can act as a host like a PC.
OTG是On-The-Go的缩写,是在USB技术的基础上发展起来的一项技术,它使USB装置摆脱了原来主从架构的限制,实现了端对端的传输模式。 OTG is the abbreviation of On-The-Go. It is a technology developed on the basis of USB technology. It makes the USB device free from the limitations of the original master-slave architecture and realizes the end-to-end transmission mode.
目前,在手机、平板电脑和相机等小型便携设备上,由于体积方面的原因,无法像台式电脑或笔记本电脑那样设置标准大小的USB type A(标准A)接口,而仅仅设有接口面积较小的micro USB接口(迷你USB接口)。如今,越来越多的带有micro USB接口的便携设备支持传统U盘使用OTG连接线与之进行数据交换,OTG连接线一端与U盘的USB type A接口相连接,OTG连接线另一端与手机等设备上的micro USB接口相连接,使得micro USB便携设备和U盘之间可交换数据。然而,一旦离开OTG连接线,传统的U盘和手机等设备之间便无法再进行数据交换,OTG连接线携带不方便,也给用户使用带来不便。At present, on small portable devices such as mobile phones, tablets, and cameras, due to volume reasons, it is not possible to set a standard size USB type A (standard A) interface like a desktop computer or a notebook computer, but only has a small interface area. Micro USB interface (mini USB interface). Nowadays, more and more portable devices with micro USB interface support traditional U disk to exchange data with OTG cable. One end of OTG cable is connected with USB type A interface of U disk, and the other end of OTG cable is connected with The micro USB interface on the device such as a mobile phone is connected, so that data can be exchanged between the micro USB portable device and the USB flash drive. However, once the OTG cable is removed, data exchange between the conventional U disk and the mobile phone cannot be performed, and the OTG cable is inconvenient to carry, which also causes inconvenience to the user.
因此,有必要提供一种使用更加方便且具有OTG功能的可移动存储装置。Therefore, it is necessary to provide a removable storage device that is more convenient to use and has an OTG function.
