具体实施方式detailed description
为了使本申请的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本申请进行进一步详细说明。应当理解，此处描述的具体实施例仅仅用以解释本申请，并不用于限定本申请。In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.
下面将通过实施例并结合附图具体地对本申请的技术方案以及本申请的技术方案如何解决上述技术问题进行详细说明。下面的实施例可以相互结合，对于相同或相似的概念或过程可能在某些实施例中不再赘述。The technical solution of the present application and how the technical solution of the present application solves the above technical problems will be described in detail below through embodiments and in conjunction with the accompanying drawings. The following embodiments may be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.
另外，本申请实施例所记载的技术方案之间，在不冲突的情况下，可以任意组合。In addition, the technical solutions described in the embodiments of the present application may be combined arbitrarily if there is no conflict.
本申请实施例提供了一种数据传输方法，应用于第一终端和第二终端之间的数据传输。其中，第一终端具体可以是Android系统的手机，其作为USB从设备，第二终端具体可以是Windows系统或Linux系统的计算机，其作为USB主设备。An embodiment of the present application provides a data transmission method, which is applied to data transmission between a first terminal and a second terminal. Wherein, the first terminal may specifically be a mobile phone with an Android system, which acts as a USB slave device, and the second terminal may specifically be a computer with a Windows system or a Linux system, which acts as a USB master device.
需要说明的是，USB主设备对USB系统进行管理、每毫秒产生一帧数据、发送配置请求对USB从设备进行配置、管理和恢复总线上的错误。通用串行总线集线器(UniversalSerialBus Hub，USB HUB)用于设备扩展连接，所有USB从设备都连接在USB HUB的端口上，USB从设备接收USB总线上的所有数据包，通过数据包的地址域来判断是不是发给自己的数据包，若地址不符，则丢弃该数据包，若地址相符，则通过响应USB主设备的数据包与USB主设备进行数据传输。It should be noted that the USB master device manages the USB system, generates a frame of data every millisecond, sends configuration requests to configure the USB slave device, manages and recovers errors on the bus. The universal serial bus hub (UniversalSerialBus Hub, USB HUB) is used for device expansion connection. All USB slave devices are connected to the port of USB HUB. Judging whether it is a data packet sent to oneself, if the address does not match, the data packet is discarded, and if the address matches, data transmission is performed with the USB master device by responding to the data packet of the USB master device.
需要说明的是，USB主设备和USB从设备之间遵循主从通信的原理，每一次的数据传输都是USB主设备发起。如果USB主设备要输出数据，则先发一个握手包，通知USB从设备，然后发送数据，USB从设备接收到数据后，再发送一个确认包。如果USB主设备要输入数据，也是先发一个握手包，通知USB从设备，USB从设备然后将准备好的数据发送给USB主设备，USB主设备再给USB从设备一个确认包。It should be noted that the principle of master-slave communication is followed between the USB master device and the USB slave device, and each data transmission is initiated by the USB master device. If the USB master device wants to output data, it first sends a handshake packet to notify the USB slave device, and then sends data. After the USB slave device receives the data, it sends a confirmation packet. If the USB master device wants to input data, it also sends a handshake packet first to notify the USB slave device, and the USB slave device then sends the prepared data to the USB master device, and the USB master device sends a confirmation packet to the USB slave device.
以下将分别对第一终端和第二终端执行的数据传输方法进行详述。The data transmission methods performed by the first terminal and the second terminal will be described in detail below respectively.

需要说明的是，在本申请的实施例中，上述创建数据传输接口的方式仅为提供的一种可选的方式，当然，第一终端还可以根据自身应用的具体系统类型，或者，其它信息和方式，完成数据传输接口的创建，本申请实施例不作限定。It should be noted that, in the embodiment of this application, the above-mentioned method of creating a data transmission interface is only an optional method provided. Of course, the first terminal can also use the specific system type of its own application, or other information and methods to complete the creation of the data transmission interface, which is not limited in this embodiment of the application.

可以理解的是，在本申请的实施例中，对于接收线程而言，数据生产者是接收线程，数据消费者为第一终端上的应用，为了防止当前缓冲区未使用完，开始下次接收时，覆盖之前缓冲区的内容，引入接收消息队列机制。It can be understood that, in the embodiment of this application, for the receiving thread, the data producer is the receiving thread, and the data consumer is the application on the first terminal. In order to prevent the current buffer from being used up, start the next reception When , overwrite the contents of the previous buffer and introduce the receiving message queue mechanism.

可以理解的是，在本申请的实施例中，对于第一终端与第二终端进行数据传输而言，如果传输的信息是有关用户的隐私数据或者第一终端的控制信息，黑客很容易伪造第二终端获取该数据。所以需要在传输前需要加验证流程，双方进行握手确认身份后再进行传输，每次传输需要进行循环冗余校验，以此来保证传输的安全性。It can be understood that, in the embodiment of the present application, for data transmission between the first terminal and the second terminal, if the transmitted information is private data about the user or control information of the first terminal, it is easy for hackers to forge the second terminal.

图4为本申请实施例提供的一种数据传输方法的流程示意图三。如图4所示，应用于第二终端的数据传输方法主要包括以下步骤：FIG. 4 is a third schematic flowchart of a data transmission method provided by an embodiment of the present application. As shown in Figure 4, the data transmission method applied to the second terminal mainly includes the following steps:
S401、在第一终端向第二终端发起数据传输的情况下，采用异步传输方式，接收第一终端利用数据传输接口的发送端点传输的目标数据。S401. When the first terminal initiates data transmission to the second terminal, use an asynchronous transmission mode to receive target data transmitted by the first terminal using a sending endpoint of a data transmission interface.
在本申请的实施例中，第二终端在第一终端向其发起数据传输的情况下，采用异步传输方式，接收第一终端利用数据传输接口的发送端点传输的目标数据。In the embodiment of the present application, when the first terminal initiates data transmission to it, the second terminal adopts an asynchronous transmission method to receive the target data transmitted by the first terminal using the sending endpoint of the data transmission interface.
需要说明的是，在本申请的实施例中，第二终端可以运行Windows或Linux操作系统，而且第二终端的USB程序可以运行在用户空间，即无需修改内核驱动。内核可以将USB消息转发到用户空间，Libusb为一套完成的USB配置库，可以使用该库根据需求进行定制配置，其提供了基于内核应用程序编程接口的抽象层。It should be noted that, in the embodiment of the present application, the second terminal can run Windows or Linux operating system, and the USB program of the second terminal can run in user space, that is, there is no need to modify the kernel driver. The kernel can forward USB messages to the user space. Libusb is a complete set of USB configuration library, which can be used to customize the configuration according to requirements, and it provides an abstraction layer based on the kernel application programming interface.
需要说明的是，在本申请的实施例中，第二终端基于Libusb支持同步传输方式和异步传输方式，在使用同步传输方式的时候，第二终端基于每次传输等待当前的传输任务完毕后才能重新创建，第一终端发送数据只有在第二终端请求时才进行发送，第二终端只有在传输任务激活时才请求发送数据。如此，当一个传输任务结束后，下一个传输任务未创建和提交前，第一终端无法进行发送数据，即使处于循环中，软件循环处理的耗时，传输任务是没有激活的。因此，简单的对时间要求不是很高的数据传输推荐使用同步传输方式，但是为满足高速率传输，就需要使用异步传输方式。It should be noted that, in the embodiment of the present application, the second terminal supports synchronous transmission mode and asynchronous transmission mode based on Libusb. When using the synchronous transmission mode, the second terminal waits for the completion of the current transmission task based on each transmission. To recreate, the first terminal sends data only when the second terminal requests it, and the second terminal only requests to send data when the transmission task is activated. In this way, when a transmission task ends, the first terminal cannot send data before the next transmission task is created and submitted. Even if it is in a loop, the transmission task is not activated due to the time-consuming software cycle processing. Therefore, it is recommended to use the synchronous transmission method for simple data transmission that is not very demanding on time, but to meet the high-speed transmission, it is necessary to use the asynchronous transmission method.
具体的，在本申请的实施例中，第二终端采用异步传输方式，接收第一终端利用数据传输接口的发送端点传输的目标数据，包括：创建多个传输任务；执行多个传输任务，进行目标数据的接收；针对多个传输任务中的每个传输任务，在任务结束时，重新激活并再次承接数据接收工作，直至完成目标数据的接收。Specifically, in the embodiment of the present application, the second terminal adopts the asynchronous transmission method, and receives the target data transmitted by the first terminal using the sending endpoint of the data transmission interface, including: creating multiple transmission tasks; executing multiple transmission tasks, performing Receiving the target data: For each transmission task in the multiple transmission tasks, when the task ends, reactivate and undertake the data receiving work again until the target data reception is completed.
可以理解的是，在本申请的实施例中，如图5所示，对于第二终端而言，每个传输任务结束，即第一终端向第二终端传输完一次数据。传输任务是用来承载传输数据工作的，传输任务可复用，即初始化时批量创建一批，等待每次传输任务传输数据完毕后，重新激活传输任务即又可承载接收第一终端发送过来的数据工作，从而支持并行传输数据，减少软件处理的延时，提高USB传输的速率。It can be understood that, in the embodiment of the present application, as shown in FIG. 5 , for the second terminal, each transmission task ends, that is, the first terminal completes one data transmission to the second terminal. The transmission task is used to carry the work of transmitting data. The transmission task can be reused, that is, a batch is created in batches during initialization, and after each transmission task completes the data transmission, the transmission task can be reactivated to carry and receive the data sent by the first terminal. Data work, so as to support parallel data transmission, reduce the delay of software processing, and increase the speed of USB transmission.
本申请实施例提供了一种数据传输方法，应用于第二终端，包括：在第一终端向第二终端发起数据传输的情况下，采用异步传输方式，接收第一终端利用数据传输接口的发送端点传输的目标数据。本申请实施例提供的数据传输方法，提高了USB数据传输的速率，且支持数据实时传输，具备实时性。The embodiment of the present application provides a data transmission method, which is applied to the second terminal, including: when the first terminal initiates data transmission to the second terminal, adopting an asynchronous transmission method, and receiving the data sent by the first terminal through the data transmission interface Destination data transmitted by the endpoint.
