具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
除非另有定义，本文所使用的所有的技术和科学术语与属于本发明的技术领域的技术人员通常理解的含义相同。本文中在本发明的说明书中所使用的术语只是为了描述具体的实施例的目的，不是旨在于限制本发明。
下面结合附图，对本发明的一些实施方式作详细说明。在各实施例之间不冲突的情况下，下述的实施例及实施例中的特征可以相互组合。
长期以来，不同类型的主机所支持的与外接的移动存储装置进行通信的信号协议不同，这就出现某些类型的主机可以直接接入移动存储装置并与移动存储装置进行数据交互，某些类型的主机必须要通过信号协议装换装置(例如读卡器)才能与移动存储装置进行数据交互，这样严重地限制了移动存储装置的易用性。例如，摄像机、照相机等拍摄装置所支持的与外接的移动存储装置进行通信的信号协议(例如PCIE协议)与笔记本电脑、膝上型电脑、台式电脑或者平板电脑等个人终端所支持的与外接的移动存储装置进行通信的信号协议(例如USB协议)不同，这样会出现移动存储装置(例如高速移动存储装置)可以直接接入拍摄装置实现数据交互，移动存储装置必须要通过信号协议装换装置(例如读卡器)才能接入个人终端实现数据交互。这就导致用户要自己判断哪些主机可以直接接入移动存储装置，哪些主机需要信号协议装换装置来接入移动存储装置，并且需要额外配置信号协议转换装置，这样使用不够方便，降低了移动存储装置的易用性。为解决上述问题，本发明实施例提供以下移动存储装置的数据传输方法、装置和存储介质，并进行具体说明。
图1为本发明实施例提供的一种移动存储装置的数据传输方法的流程示意图；本申请实施例提供的该方法100可以由移动存储装置执行，移动存储装 置包括：通用数据接口和存储介质。该方法100包括以下步骤：
101：检测通用数据接口连接的主机的类型。
102：若主机类型为第一类型时，利用第一信号协议接收主机通过通用数据接口发送的数据，并利用第一信号协议将数据存储到存储介质中。
103：若主机类型为第二类型时，利用第二信号协议接收将主机通过通用数据接口发送的数据发送至信号协议转换装置，利用信号协议转换装置将符合第二信号协议的数据转换为符合第一信号协议的数据，并利用第一信号协议将数据存储到存储介质中。
需要说明的是，本申请实施例移动存储装置可以是存储器、存储棒等可以实现移动存储功能的设备或者装置，移动存储装置便携带，方便用户使用。
以下针对上述步骤进行详细地阐述：
101：检测通用数据接口连接的主机的类型。
其中，通用数据接口是指较为广泛使用的接口，用于数据传输，如可以为USB(Universal Serial Bus，通用串行总线)接口。如果还有其它数据接口较为广泛应用，也可以是其它数据接口，此处不进行过多限制。
主机是指用于与通过数据接口进行连接的设备，该主机可以有不同类型。如第一类型和第二类型。其中，第一类型的主机可以为拍摄装置，如照相机、摄像机等。第二类型的主机可以为个人终端，如笔记本电脑、膝上型电脑、台式电脑、平板电脑等。
通过移动存储装置，如存储棒，可以检测到与其连接的主机类型。例如，如图2所示，该移动存储装置207可以包括通用数据接口A201，即通用数据接口，如，USB tpyeC接口(是一种USB接口外形标准，既可以应用于PC(Personal Computer，个人计算机，可以作为主设备)，又可以应用于外部设备(从设备，如手机)的接口类型)。该移动存储装置207还包括存储介质206，所述存储介质可以为数据存储装置，如SSD或者存储卡，更具体的可以是M.2记忆卡(M.2是一种接口方案，可以兼容多种通信协议，如，PCIE(peripheral component interconnect express，一种高速串行计算机扩展总线标准)协议)、CFexpress卡(一种存储卡，CFexpress卡type B)等。这样可以达到超过1000MB/s(兆字节每秒)的读写速率。
除此以外，该移动存储装置207还包括两个开关，如“开关1”202和“开关2”205。在这两个开关之间还具有两个通道，分别对应不同的协议通路。 其中一个是通过电路板走线203实现的通道，另一个是通过信号协议转换装置204实现的通路。通过两个开关来切换不同的通道。
具体的，检测通用数据接口连接的主机的类型，包括：获取通用数据接口中预设管脚的电平信号；根据电平信号确定与通用数据接口连接的主机的类型。
例如，根据前文所述，如图2所示，移动存储装置207，如存储棒，可以通过其通用数据接口A201，如，USB tpyeC接口，更具体的可以是USB tpyeC母座与主机进行连接。
更具体的，如图3所示，将移动存储装置207，如存储棒，通过其通用数据接口A201，如USB tpyeC母座与主机进行连接。在连接的时候，还需要通过一个连接装置301进行主机与移动存储装置207的USB tpyeC母座进行连接。在该连接装置301中可以包括连接接口302以及通用数据接口B303。其中，连接接口302可以是一个CFexpress假卡(其可以是个CFexpress标准卡)，即其只是用于与CFexpress卡座进行连接，同时还与通用数据接口B303连接，但不实现数据的读写，只是进行数据的传输。通用数据接口B303可以是USB tpyeC接口，更具体的可以是USB tpyeC公座，与USB tpyeC母座相匹配。使得通过该连接接口302即可以将主机与移动存储装置207进行连接。更具体的是，主机上的CFexpress卡座与移动存储装置207进行连接。
需要说明的是，在该连接方式下，上述连接装置也可以称为存储仓。该存储仓可以用于连接主机(更具体的可以是主机上的卡座)与移动存储装置。即该移动存储装置可以搭配存储仓来使用。
利用CFexpress假卡的物理接口，实现了CFexpress卡(Type B，即CFexpress假卡)和移动存储装置的兼容适配。
除了此种方式的连接外，还可以通过USB数据线的方式进行连接。如图5所示，根据前文所述可知，在主机与移动存储装置207连接的时候，还可以通过USB数据线503分别与通用数据接口B303，可以是USB tpyeC接口，以及主机的USB数据接口501进行连接。
无论通过上述哪种连接方式进行与主机的连接，连接后，可以获取到该通用数据接口(可以如图4所示的通用数据接口A201)的预设管脚pin获取到对应的电平信号，或者说，连接后，移动存储装置可以获取到该通用数据接口(如图4所示的通用数据接口A201)上的预设管脚pin的电平信号。移动存 储装置根据获取到的电平信号来确定对应的主机类型是第一类型，如照相机，还是第二类型，如电脑。
其中，获取通用数据接口中预设管脚的电平信号，包括：获取通用数据接口中目标电源管脚或目标接地管脚的电平信号。
其中，目标电源管脚是指与供电电压VCC相关的管脚。目标接地管脚是指与接地端GND相关的管脚。
具体的，在实现的时候，可以根据USB TYPEC接口的常规管脚pin定义，通过差分线的协议复用为USB协议差分对或者PCIE协议数据时钟差分对来时线对应协议的管脚定义。在定义后，如图6所示，其定义了USB协议的供电电压VCC管脚601(可以定义了四个，但图6中仅示出了三个)，如USB3.1gen2协议的供电电压VCC管脚601。然后可以通过对一个供电电压管脚VCC601进行特殊定义为开关SW供电电压VCC管脚602，来实现USB3.1gen2协议接口的转换(即该对应的管脚转换前是供电电压VCC管脚601，此处图6中仅示出了其转换后的开关SW供电电压VCC管脚602)。
相应的，如图7所示，根据前文所知，其也可以定义了PCIE协议(如PCIE3.0协议)的供电电压VCC管脚601(可以定义了四个，但图7中仅示出了三个)，如PCIE3.0协议的供电电压VCC管脚601。然后可以通过对一个供电电压管脚VCC601进行特殊定义为开关SW接地端GND管脚702，来实现PCIE3.0协议接口的转换(即该对应的管脚转换前是供电电压VCC管脚601，此处图7中仅示出了其转换后的开关SW接地端GND管脚702)。
由此，通过自定义管脚来实现了高速接口切换的功能。通过利用一个供电电压VCC管脚作为开关SW供电电压VCC管脚或开关SW接地端GND管脚702，可以使得支持实现USB3.1gen2接口和PCIE3.0接口的自适应切换。
基于此，无论通过上述哪种连接方式进行与主机的连接，在连接后移动存储装置均可以通过获取通用数据接口(如图4所示的通用数据接口A201)中目标电源管脚(如开关SW供电电压VCC管脚)或目标接地管脚(如开关SW接地端GND管脚)的电平信号。
更具体的，根据电平信号确定与通用数据接口连接的主机的类型，包括：若目标电源管脚的电平信号为低电平信号，确定主机的类型为第一类型；若目标电源管脚的电平信号为高电平信号，确定主机的类型为第二类型。
例如，根据前文所述，如图4所示，当移动存储装置207与照相机等主机 连接时，在连接装置301中，其通过接地端401与移动存储装置207进行信号连接，或者说通过该接地端401来发送信号。如，该接地端401通过通用数据接口B303，如USB tpyeC公座，发送低电平信号至通用数据接口A201，如USB tpyeC母座，则该母座的开关SW接地端GND管脚接收到低电平信号，由此，移动存储装置207也接收到了该低电平信号，从而根据该低电平信号可以确定主机类型是第一类型，如照相机等。
如图5所示，当移动存储装置207与电脑等主机连接时，在USB数据线503中，其通过供电电压VCC502与移动存储装置207进行信号连接，或者说通过该供电电压VCC502与来发送信号。如，该供电电压VCC502与通过通用数据接口B303，如USB tpyeC公座，发送高电平信号至通用数据接口A201，如USB tpyeC母座，则该母座的开关SW供电电压VCC管脚接收到高电平信号，由此，移动存储装置207也接收到了该高电平信号，从而根据该高电平信号可以确定主机类型是第二类型，如电脑等。
除了该种方式来确定主机的类型，还可以通过用户自主进行确定，用户可以通过交互装置来确定主机类型。降低成本，也可以提高准确率。
具体地，移动存储装置包括交互装置，检测通用数据接口连接的主机的类型，包括：通过交互装置选择用户的主机类型指示操作；根据检测到的操作确定通用数据接口连接的主机的类型。
其中，交互装置可以是外围按键或者拨动开关。该按键或者开关可以设置在移动存储装置上或者遥控器上均可。
例如，用户可以通过查看移动存储装置与哪个类型的主机连接，如当前与电脑连接，则用户通过点击第二类型的按键的操作，向移动存储装置发送指示。移动存储装置根据接收到的或检测到的点击按键的操作，如点击第二类型的按键，则确定出主机类型为第二类型。第一类型也是相似的，就不再赘述了，其可以是点击第一类型的按键操作。
此外，拨动开关也是形似的，用户通过拨动开关的操作来让移动存储装置确定对应的操作，来确定对应的主机类型，就不再赘述了。
102：若主机类型为第一类型时，利用第一信号协议接收主机通过通用数据接口发送的数据，并利用第一信号协议将数据存储到存储介质中。
其中，第一信号协议可以是指第一信号协议为PCIE协议，如PCIE3.0协议。
例如，根据前文所述，如图4所示，当移动存储装置207确定主机类型为 第一类型，如照相机。则通过通用数据接口A201，如USB tpyeC母座，接收到的低电平信号，来控制高速信号开关switch的SW信号，从而来控制“开关1”202和“开关2”205的信号连通方向。其中，如“开关1”202和“开关2”205可以为单刀双掷开关。即控制这两个单刀双掷开关的第一信号连通方向403，当连接到照相机时，可以是通过连接装置301，即存储仓进行连接的。此时，根据前文所知，SW信号被存储仓的接地端401拉低，即接收到了低电平信号。则高速信号开关switch，即“开关1”202和“开关2”205被切换到电路板走线203所在通道，即高速PCB(Printed Circuit Board，印制电路板)走线的通道，由此，存储介质206，如M.2记忆卡可以通过USB TYPEC母座，走PCIE3.0协议，经过存储仓的CFexpress TypeB卡座，连接到照相机，实现高速视频码流的读写。
需要说明的是，对于电路板走线通道，是指通过电路板上的走线实现的通道。即通过电路板来实现PCIE3.0协议对数据的读写。而需要通过在电路板上进行布线来实现协议的读取。
对于从存储介质写入数据至第一类型的主机时，具体的可以为，该方法100还包括：若主机类型为第一类型时，利用第一信号协议从存储介质中获取数据，并利用第一信号协议通过通用数据接口发送给主机。
该过程是上述读取过程的逆过程，就不再过多赘述了。仅说明：由于当前通道是电路板走线通道，通过该通道从存储介质，如M.2记忆卡中读取数据，并根据该通道传输至照相机的存储卡。
此外，如图4所示，其中，接地端401通过信号传输链路402使得两个开关进行了第一信号连通方向403被确定。该第一信号连通方向403对应的电路板走线203所在通道。
由于USB接口的存储器不能满足高速码流的速率需求，所以摄像机、照相机等第一类型的主机或设备的高速存储器大多采用PCIE(peripheral component interconnect express，一种高速串行计算机扩展总线标准)协议的存储器。这就导致该类型的存储器在连接电脑这种第二类型的主机或设备的时候导出数据时需要额外的读卡器，不够方便。
所以在连接第二类型的主机的时候可以采用如下方式进行数据的读写。
103：若主机类型为第二类型时，利用第二信号协议接收将主机通过通用数据接口发送的数据发送至信号协议转换装置，利用信号协议转换装置将符 合第二信号协议的数据转换为符合第一信号协议的数据，并利用第一信号协议将数据存储到存储介质中。
其中，第二信号协议可以为USB协议，如USB3.1gen2协议。
例如，根据前文所述，如图5所示，当移动存储装置207确定主机类型为第二类型，如电脑。则通过通用数据接口A201，如USB tpyeC母座，接收到的高电平信号，来控制高速信号开关switch的SW信号，从而来控制“开关1”202和“开关2”205的信号连通方向。其中，如“开关1”202和“开关2”205可以为单刀双掷开关。即控制这两个单刀双掷开关的第二信号连通方向504，当连接到电脑时，可以是通过USB数据线503进行连接的。此时，根据前文所知，SW信号被USB数据线503的供电电压VCC拉高，即接收到了高电平信号。则高速信号开关switch，即“开关1”202和“开关2”205被切换到信号协议转换装置204，如PICE转USB接口芯片的通道。由此，存储介质206，如可以通过USB TYPEC母座，将USB协议转换为PCIE协议，如USB3.1gen2协议转换为PCIE3.0协议，使得从电脑接收到的USB3.1gen2协议的数据转换为PCIE3.0协议的数据，然后存储至M.2记忆卡，即完成数据的读取。或者，M.2记忆卡可以通过信号协议转换装置204，将PCIE协议转换为USB协议，再经过USB TYPEC母座和USB数据线503，连接到电脑，实现电脑与移动存储装置207，如存储棒的数据写入。就不再赘述了。
需要说明的是，对于信号协议转换装置，其即可以是实现，USB协议转换为PCIE协议，也可以实现PCIE协议转换为USB协议。其也可以作为另一个通道，即PCIE转USB接口芯片的通道。由此可知，该装置是可以通过一个芯片来实现的。该读取的过程中，该芯片将USB协议的数据转换为PCIE协议的数据，再通过上述电路板来实现PCIE3.0协议对数据的读取。而当写入的过程中，则是该芯片将来自上述电路板的PCIE协议的数据(从记忆卡中获取到的数据)转换为USB协议的数据，再通过后续的通用数据接口A201等对USB协议的数据的写入，就不再赘述了。该芯片可以与上述电路板进行连接。
基于此，本实施例实现了USB3.1gen2与PCIE3.0的自适应切换，既保证了连接照相机以及摄影机等设备的高速的视频码流存储(稳态700MB/s的写入)，又保证了连接电脑时的便捷使用。实现了速率和便捷性的两者兼得的效果，同时又做到了协议自适应的切换，做到了极优的用户体验。
对于从存储介质写入数据至第二类型的主机时，具体的可以为，该方法 100还包括：若主机类型为第二类型时，利用第一信号协议将从存储介质中获取的数据发送至信号协议转换装置，利用信号协议转换装置将符合第一信号协议的数据转换为符合第二信号协议的数据，并利用第二信号协议通过通用数据接口将数据发送给主机。
该过程是上述第二类型的主机读取过程的逆过程，就不再过多赘述了。仅说明：由于当前通道是PICE转USB接口芯片的通道，通过该上述电路板以及该通道存储介质，如M.2记忆卡中将数据进行读取，并根据电路板以及该通道传输至电脑，完成写入过程。
在具体的应用过程中，如图8所示，照相机804的CFexpress卡座802既可以采用配合标准的CFexpress Type B卡来使用，也可以配合本申请实施例提供的移动存储装置来使用。实现了CFexpress Type B卡和移动存储装置207的兼容适配。其中，存储仓805通过其CFexpress假卡801插入到照相机804的CFexpress卡座802中。在CFexpress假卡801上设置有结构防呆803，以使该假卡以及存储仓805正确插入到照相机中。
如图9所示，照相机804在插入了存储仓805后，继续插入存储移动装置207，如存储棒。也可以在存储移动装置207设置结构防呆，并通过该结构防呆可以实现PCIE3.0接口的防反插，加上前文所述的上述管脚的设置实现接口转换功能。
