[0052] Those skilled in the art will understand that Figure 1 The structure shown in the figure does not constitute a limitation on the data transmission device, and may include more or less components than shown in the figure, or combine certain components, or arrange the components differently.

[0053] like Figure 1 As shown, the memory 1005 as a storage medium may include an operating system, a network communication module, a user interface module and a data transmission program.

[0055] Based on the above hardware structure, an embodiment of the data transmission method of the present invention is proposed.

[0056] Reference Figure 2 , Figure 2 FIG. 1 is a flow chart of a first embodiment of a data transmission method according to the present invention.

[0057] In a first embodiment, the data transmission method comprises the following steps:

[0058] Step S10: acquiring target spectrum resources and target contention priorities configured by the routing device.

[0059] It should be noted that the executor of this embodiment is a data transmission device, and may also be other devices that can achieve the same or similar functions, such as a data transmission system, etc. This embodiment does not limit this. In this embodiment, the data transmission system is taken as an example for explanation.

[0060] It should be understood that the target spectrum resources refer to the spectrum resources allocated for data transmission, which are the maximum spectrum resources that can be allocated. The target contention priority refers to the contention priority configured for data transmission, which is the highest priority that can be set. The target spectrum resources and the target contention priority are both configured by a routing device, which can be a router.

[0061] Step S20, obtaining delay-sensitive data to be transmitted.

[0062] It can be understood that the delay-sensitive data to be transmitted refers to data that needs to be transmitted from the target smart device to the vehicle computer. The delay-sensitive data to be transmitted may be vehicle control data, and the target smart device may be AR glasses.

[0063] Step S30: transmitting the delay-sensitive data to be transmitted according to the target spectrum resources and the target contention priority through the routing device.

[0064] It should be understood that after determining the target spectrum resources and the target contention priority, the delay-sensitive data to be transmitted is transmitted from the target smart device to the vehicle computer through the routing device.

[0065] Furthermore, step S30 includes: transmitting the delay-sensitive data to be transmitted from the target smart device to the routing device according to the target spectrum resources and the target competition priority; transmitting the delay-sensitive data to be transmitted from the routing device to the vehicle computer according to the target spectrum resources and the target competition priority.

[0066] It can be understood that the transmission path of the delay-sensitive data to be transmitted is from the target smart device -> routing device -> vehicle computer. Specifically: first, the delay-sensitive data to be transmitted is transmitted from the target smart device to the routing device according to the target spectrum resources and target competition priority; secondly, the delay-sensitive data to be transmitted is transmitted from the routing device to the vehicle computer according to the target spectrum resources and target competition priority.

[0067] It should be noted that the reference Figure 3 , Figure 3The figure is a schematic diagram of the overall process, including a target smart device, a target kernel, a routing device and a vehicle computer. The vehicle computer can be the abbreviation of an in-vehicle infotainment product set in a vehicle. The specific process is: the target smart device sends its own media access control address and the vehicle computer's media access control address to the target kernel through an application program interface, and the target kernel generates a target format protocol request frame after receiving the target smart device's media access control address and the vehicle computer's media access control address. Then the target kernel sends the target format protocol request frame to the routing device, and the routing device parses the target smart device's media access control address and the vehicle computer's media access control address after receiving the target format protocol request frame. The target smart device receives the media access control address and data stream priority of the target smart device, and then configures the target spectrum resources and target contention priority according to the media access control address of the target smart device, the media access control address of the vehicle computer, and the data stream priority. The target spectrum resources and target contention priority are encapsulated into a target format protocol reply frame, and then the target format protocol reply frame is sent to the target smart device. After receiving the target format protocol reply frame, the target smart device parses the target spectrum resources and target contention priority, and then transmits the delay-sensitive data to be transmitted from the target smart device to the routing device according to the target spectrum resources and the target contention priority, and then transmits it from the routing device to the vehicle computer.

[0068] This embodiment obtains the target spectrum resources and target contention priorities configured by the routing device; obtains the delay-sensitive data to be transmitted; and transmits the delay-sensitive data to be transmitted through the routing device according to the target spectrum resources and target contention priorities. In the above manner, the target spectrum resources and target contention priorities configured by the routing device are obtained, and then the target spectrum resources and target contention priorities are used to transmit the delay-sensitive data to be transmitted from the target smart device to the vehicle computer, thereby achieving low-latency transmission of data and improving user experience.

[0069] In one embodiment, if Figure 4 Based on the first embodiment, a second embodiment of the data transmission method of the present invention is proposed, wherein step S10 includes:

[0070] Step S101, obtaining a target format protocol reply frame sent by a routing device.

[0071] It should be understood that the target format protocol reply frame refers to a data frame that encapsulates the standard spectrum resources and target competition priority. The target format protocol reply frame can be an 802.11ADDTS Response frame, which can be sent to the target smart device through a routing device.

[0072] Further, step S101 includes: receiving a target format protocol request frame sent by a target kernel through a routing device; parsing the target format protocol request frame to obtain a media access control address of a target smart device, a media access control address of a vehicle computer, and a data stream priority; configuring target spectrum resources and target competition priority according to the media access control address of the target smart device, the media access control address of the vehicle computer, and the data stream priority through a routing device; encapsulating the target spectrum resources and target competition priority into a target format protocol reply frame, and sending the target format protocol reply frame by the routing device.

[0073] It can be understood that after receiving the target format protocol request frame sent by the target kernel, the routing device parses the target format protocol request frame to obtain the media access control address (MAC) of the target smart device, the MAC address of the vehicle computer, and the data stream priority. After parsing the MAC address of the target smart device, the MAC address of the vehicle computer, and the data stream priority, the routing device will configure the target spectrum resources and target contention priority according to the MAC address of the target smart device, the MAC address of the vehicle computer, and the data stream priority. At this time, the target spectrum resources are the maximum spectrum resources that can be allocated, and the target contention priority is the highest priority that can be set. After configuring the target spectrum resources and the target contention priority, the target spectrum resources and the target contention priority are encapsulated into a target format protocol reply frame and then sent to the target smart device.

[0074] Furthermore, the target spectrum resources and target competition priority are configured by the routing device according to the media access control address of the target smart device, the media access control address of the vehicle computer, and the data stream priority, including: obtaining the current state of the device connected to the routing device; determining the used spectrum resources according to the current state of the device connected to the routing device; obtaining idle spectrum resources according to the used spectrum resources; configuring the idle spectrum resources according to the media access control address of the target smart device, the media access control address of the vehicle computer, and the data stream priority to obtain the target spectrum resources; configuring the target competition priority according to the media access control address of the target smart device, the media access control address of the vehicle computer, and the data stream priority through a preset priority mapping relationship.

[0075] It should be understood that the current state of the device connected to the routing device includes a working state and a non-working state. A device in a non-working state will not occupy spectrum resources. That is, after the current state of the device connected to the routing device determines the used spectrum resources, the idle spectrum resources are calculated using the used spectrum resources and the total spectrum resources. Then, the idle spectrum resources are configured according to the media access control address of the target smart device, the media access control address of the vehicle computer, and the data stream priority to obtain the target spectrum resources. For example, 95% of the idle spectrum resources are configured to transmit the delay-sensitive data to be transmitted. The target competition priority is configured according to the media access control address of the target smart device, the media access control address of the vehicle computer, and the data stream priority using a preset priority mapping relationship. The preset priority mapping relationship is used to store the mapping relationship between the media access control address, the data stream priority, and the target competition priority. The higher the priority of the data stream, the higher the configured target competition priority.

[0076] Furthermore, the receiving of the target format protocol request frame sent by the target kernel through the routing device includes: obtaining the media access control address of the target smart device and the media access control address of the vehicle computer sent by the target smart device through the target kernel; setting the type of the data stream; filling the media access control address of the target smart device and the media access control address of the vehicle computer into the data stream after the type is set; setting the priority of the data stream after the media access control address is filled to generate a target format protocol request frame, and sending the target format protocol request frame; receiving the target format protocol request frame sent by the target kernel through the routing device.

[0077] It can be understood that after receiving the media access control address of the target smart device and the media access control address of the vehicle computer, the target kernel will generate a target format protocol request frame. The target format protocol request frame includes a TClass field and a TSpec field. The content of the TClass field is to set the data stream type. The data stream type can be set to the Ethernet type, and then the media access control address of the target smart device and the media access control address of the vehicle computer are filled in the data stream after the type is set. The content of the TSpec field is to set the priority of the data stream. The data stream after the media access control address is filled can be set to a dedicated high priority. After the setting is completed, a target format protocol request frame is generated, and then the target kernel sends the target format protocol request frame to the routing device.

[0078] Furthermore, obtaining the media access control address of the target smart device and the media access control address of the vehicle computer sent by the target smart device through the target kernel includes: obtaining the media access control address of the target smart device and the media access control address of the vehicle computer; sending the media access control address and the media access control address of the vehicle computer through the target smart device and the program interface; obtaining the media access control address of the target smart device and the media access control address of the vehicle computer sent by the target smart device through the target kernel.

[0079] It should be understood that before data transmission, the target smart device will obtain its own media access control address and the media access control address of the vehicle computer, and then send the media access control address of the target smart device and the media access control address of the vehicle computer to the target kernel through the program interface. After receiving the media access control address of the target smart device and the media access control address of the vehicle computer, the target kernel generates a target format protocol request frame, which can be an 802.11ADDTS Request frame.

[0080] Step S102: parsing the target format protocol reply frame through the target intelligent device to obtain the target spectrum resources and target contention priority configured by the routing device.

[0081] It is understandable that after receiving the target format protocol reply frame, the target intelligent device parses the target format protocol reply frame to obtain the target spectrum resources and target contention priority configured by the routing device.

[0082] This embodiment obtains a target format protocol reply frame sent by a routing device; the target format protocol reply frame is parsed by a target intelligent device to obtain the target spectrum resources and target contention priority configured by the routing device; in the above manner, the target format protocol reply frame sent by the routing device is obtained, and then the target intelligent device parses the target format protocol reply frame to obtain the target spectrum resources and target contention priority configured by the routing device, thereby effectively improving the accuracy of obtaining the target spectrum resources and target contention priority, thereby achieving the purpose of low-latency data transmission.

[0083] In addition, an embodiment of the present invention further provides a storage medium, on which a data transmission program is stored. When the data transmission program is executed by a processor, the steps of the data transmission method described above are implemented.

[0084] Since the storage medium adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.

[0085] In addition, refer to Figure 5The embodiment of the present invention further provides a data transmission device, the data transmission device comprising:

[0086] The acquisition module 10 is used to acquire the target spectrum resources and target contention priority configured by the routing device.

[0087] The acquisition module 10 is also used to acquire delay-sensitive data to be transmitted.

[0088] The transmission module 20 is used to transmit the delay-sensitive data to be transmitted according to the target spectrum resources and the target competition priority through the routing device.

[0089] This embodiment obtains the target spectrum resources and target contention priorities configured by the routing device; obtains the delay-sensitive data to be transmitted; and transmits the delay-sensitive data to be transmitted through the routing device according to the target spectrum resources and target contention priorities. In the above manner, the target spectrum resources and target contention priorities configured by the routing device are obtained, and then the target spectrum resources and target contention priorities are used to transmit the delay-sensitive data to be transmitted from the target smart device to the vehicle computer, thereby achieving low-latency transmission of data and improving user experience.
