Problems solved by technology

[0003] But at the same time, it is difficult to deploy roadside equipment that adapts to the WAVE protocol, which is still a major problem that plagues the development of the Internet of Vehicles system.
This is mainly because the WAVE protocol is a short-distance communication technology. Therefore, in the existing technology, such roadside equipment needs to be deployed in large quantities on the roadside, resulting in high networking costs for the Internet of Vehicles.

Embodiment 1

[0025] figure 1 It is a schematic flowchart of a data processing method provided in Embodiment 1 of the present invention. The method provided in the embodiment of the present invention can be executed by a wireless router, such as figure 1 As shown, the data processing methods include:

[0026] Step 101 , using time division multiplexing to receive packets at the physical layer based on the frequency points of the WAVE protocol and the frequency points of the WiFi protocol respectively.

[0027] Specifically, according to the period of broadcasting beacon frames in the WiFi protocol, the packets are received at the physical layer based on the frequency points of the WAVE protocol and the frequency points of the WiFi protocol. As a possible implementation, when the first beacon frame is broadcast, the message is received at the frequency point based on the WAVE protocol at the physical layer; when the second beacon frame is broadcast, the message is received at the frequency ...

Embodiment 2

[0040] Figure 4 It is a schematic flowchart of another data processing method provided in Embodiment 2 of the present invention. The method provided in the embodiment of the present invention can be executed by a wireless router, such as Figure 4 As shown, the data processing methods include:

[0041] Step 401, at the MAC layer, use the WAVE protocol stack to perform protocol processing on the first message that needs to be sent based on the frequency point of the WAVE protocol.

[0042] Specifically, in image 3 In the software architecture shown, the WAVE MAC protocol stack can be controlled by the MAC layer management entity to perform protocol processing on the first message received at the frequency point based on the WAVE protocol, and the WiFi stack and the WiFi MAC protocol stack can process the first message based on the WiFi protocol. Protocol processing is performed on the second packet received by the frequency point.

[0043] Step 402 , at the MAC layer, use ...

Embodiment 3

[0051] Figure 5 A schematic structural diagram of a data processing device 50 provided in Embodiment 3 of the present invention, as shown in Figure 5 As shown, the data processing device 50 includes: a receiving module 51 , a first processing module 52 and a second processing module 53 .

[0052] The receiving module 51 is configured to control the physical layer to receive packets based on the WAVE protocol and the WiFi protocol respectively.

[0053] The receiving module 51 is specifically configured to receive messages at the physical layer based on the frequency points of the WAVE protocol and the frequency points of the WiFi protocol according to the period of broadcasting beacon frames in the WiFi protocol.

[0054] The first processing module 52 is connected with the receiving module 51, and is used to process the first message received based on the WAVE protocol by using the WAVE protocol stack at the MAC layer.

[0055] The second processing module 53 is connected...

Abstract

An embodiment of the invention provides a data processing method and device, a wireless router and an Internet-of-Vehicles system. Via adoption of a time division multiplexing mode, messages are received and sent on a physical layer respectively via a WAVE protocol-based frequency point and a WiFi protocol-based frequency point; a first message which is based on a WAVE protocol is subjected to protocol processing operation on an MAC layer via adoption of a WAVE protocol stack; a second message which is based on a WiFi protocol is subjected to the protocol processing operation on the MAC layer via adoption of a WiFi protocol stack; a time division multiplexing mode and a frequency division multiplexing mode are combined, integrated processing of messages based on different protocols can be realized, a conventional WiFi protocol-based wireless router is enabled to be compatible with the WAVE protocol, functions of a conventional wireless router can be increased, separate deployment of a road side device which only supports the WAVE protocol can be prevented, costs of Internet-of-Vehicles networking can be reduced, and a technical problem that high Internet-of-Vehicles networking cost is caused when technologies of the prior art are adopted can be addressed.

Description

technical field [0001] The invention relates to the Internet of Vehicles technology, in particular to a data processing method and device, a wireless router and an Internet of Vehicles system. Background technique [0002] With the continuous advancement of Internet technology and intelligent transportation technology, the Internet of Vehicles system including vehicle equipment and roadside equipment has developed rapidly. At present, in order to adapt to frequent link disconnection and reconnection in the Internet of Vehicles system, and To meet the special needs of fast access, the Wireless Access in Vehicular Environment (WAVE) protocol dedicated to the Internet of Vehicles system has emerged as the times require. The WAVE protocol, as a dedicated short-range communication technology (Dedicated Short Range Communications, DSRC), reduces the time required for the original authentication and authentication, thereby greatly shortening the time required to establish a connect...
