Embodiment 1

[0051] See figure 1 , figure 1 It is a flow chart of a data transmission method provided by the embodiment of this application. It should be noted that the method provided by this embodiment is a method applied to a switching device, and the switching device is set between the SATA hard disk and the target device , including multiple controllers, these controllers include at least one main controller and at least one backup controller, and ensure uninterrupted data transmission between the SATA hard disk and the target device by switching between different controllers, which includes the following steps :

[0052] S101: judging whether the data transmission path established by the main controller is interrupted;

[0053] The purpose of this step is to determine whether the data transmission path established by the main controller is interrupted, wherein the data transmission path is a path established between the SATA hard disk and the target device for data transmission, an...

Embodiment 2

[0069] See figure 2 , figure 2 It is a flow chart of another data transmission method provided by the embodiment of the present application. On the basis of the first embodiment, this embodiment provides a specific, simple and easy implementation method, including the following steps:

[0070] S201: Determine whether any keep-alive connection data packets sent by the target device have not been received within the first preset time interval;

[0071] In this embodiment, it is judged whether the data transmission path established by the main control is interrupted according to whether no keep-alive connection data packet sent by the target device is received within the first preset time interval. It should be noted that whether the keep-alive connection data packet is received is counted according to the connection between the main controller and the target device.

[0072] S202: The data transmission path established by the main controller has been interrupted;

[0073] T...

Embodiment 3

[0082] see below image 3 , image 3 A structural block diagram of a data transmission system provided in an embodiment of the present application, the data transmission system is applied to a switching device, the switching device is arranged between a SATA hard disk and a target device, and the system may include:

[0083] The path interruption judging unit 100 is used to judge whether the data transmission path established by the main controller is interrupted; wherein, the data transmission path is a path established between the SATA hard disk and the target device for data transmission;

[0084] The standby controller switching unit 200 is used for disconnecting the connection between the main controller and the SATA hard disk and the target device when the data transmission path established by the main controller is interrupted, and establishing any available standby controller and the SATA hard disk and the target device connection between

[0085] The main controller...

Abstract

The invention discloses a data transmission method, which uses a switching device additionally provided between the SATA hard disk and the target device to selectively establish the data transmissionpath between the SATA hard disk and the target device by means of a plurality of controllers in the switching device; When any controller fails, it can be conveniently and flexibly switched to anothercontroller to quickly recover the data transmission path, thereby ensuring the data exchange between the SATA hard disk and the target device, significantly reducing the data transmission interruption problem caused by the only controller failure, and obtaining a better effect. At that same time, the invention also discloses a data transmission system, a switching device and a computer-readable storage medium, which have the above beneficial effects.

Description

technical field [0001] The present application relates to the technical field of data transmission, and in particular to a data transmission method, system, switching device, and computer-readable storage medium. Background technique [0002] As a carrier for large-capacity storage of data, hard disks have been widely used in various electronic devices, and one of the hard disks is a SATA hard disk. [0003] The SATA hard disk is a hard disk manufactured based on the SATA standard. The full English name of SATA is Serial Advanced Technology Attachment. The SATA standard provides a manufacturing standard for data transmission interfaces, so that hard disks manufactured based on this standard can use the same interface to realize data transmission. , so SATA hard drives are also called serial hard drives. [0004] However, the SATA hard disk manufactured based on the SATA standard has only one interface that can be used to receive / send data, so it can only be connected to an ...
