Embodiment 1

[0029] The embodiment of the present invention provides an emergency communication method for the Internet of Vehicles, which is applied to the roadside equipment side of the Internet of Vehicles communication system. In addition to the composition of the traditional roadside equipment, the roadside equipment is also equipped with a satellite communication module. It is used to realize the satellite communication function of central nodes such as roadside equipment and servers. It should be noted that the above satellite communication module works with reference to the working principle of the satellite communication system in the prior art, and will not be repeated here. Such as figure 2 As shown, the vehicle networking emergency communication method specifically includes the following steps:

[0030] Step S101: Monitor the communication status of the backhaul link. In practical applications, the RSU of the Internet of Vehicles, that is, the roadside equipment, sends V2X me...

Embodiment 2

[0037] An embodiment of the present invention provides an emergency communication method for the Internet of Vehicles, which is applied to the roadside device end of the Internet of Vehicles communication system. The emergency communication method for the Internet of Vehicles specifically includes the following steps:

[0038] Step S201: Monitor the communication status of the backhaul link. Specifically, in the embodiment of the present invention, the method for monitoring the communication status of the backhaul link specifically includes the following steps:

[0039] Step S2011: Send communication confirmation information to the central node according to a preset period. In practical applications, a backhaul link monitoring module is set in the RSU, which sends confirmation information to the central node at a certain period, and the central node replies to the feedback information after receiving the confirmation information. The communication status of the backhaul link ...

Embodiment 3

[0047] An embodiment of the present invention provides an emergency communication method for the Internet of Vehicles, which is applied to the roadside device end of the Internet of Vehicles communication system. The emergency communication method for the Internet of Vehicles specifically includes the following steps:

[0048] Step S301: Monitor the communication status of the backhaul link. Specifically, in the embodiment of the present invention, the method for monitoring the communication status of the backhaul link specifically includes the following steps:

[0049] Step S3011: Monitor the physical layer parameters of backhaul link communication. In practical applications, a backhaul link monitoring module is set in the RSU, which can measure the physical layer parameters of the backhaul link in real time, including but not limited to the power, field At least one of intensity, reference signal, pilot signal, current, etc. is measured.

[0050] Step S3012: Determine whet...

Abstract

The invention provides an Internet of Vehicles emergency communication method, device and system. The method comprises the following steps: monitoring the communication state of a return link; when the communication of the return link is interrupted, starting an emergency communication mode; carrying out format conversion on the first communication data sent by each Internet of Vehicles terminal and the second communication data sent by the central node according to a preset communication data protocol to generate corresponding first emergency communication data and second emergency communication data; and sending the first emergency communication data to the central node through a preset satellite communication link, and sending the second emergency communication data to each Internet ofVehicles terminal through an Internet of Vehicles communication link. Normal communication between the central node and vehicles in the communication interruption area is guaranteed in a satellite communication mode. Therefore, communication links between vehicles and roadside equipment in the disaster area and the outside can be established rapidly, so that the outside can know the distribution situation of the vehicles or personnel in the disaster area rapidly and issue disaster relief scheduling instructions, evacuation path planning schemes and other information to the vehicles or personnel in the disaster area.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a method, device and system for emergency communication of the Internet of Vehicles. Background technique [0002] The wireless communication technology of the Internet of Vehicles has developed rapidly in recent years, such as figure 1 The shown LTE-based Internet of Vehicles wireless communication system passes on-board equipment (On-Board Unit referred to as OBU) (Internet of Vehicles terminal equipment includes vehicle-mounted terminal equipment and mobile terminal equipment handheld by pedestrians), roadside equipment (Road Side Unit referred to as RSU) , The OBU that supports the Uu interface of the cellular network is connected to the wireless communication base station, and the RSU is connected to the central nodes such as the background server and the dispatching command center through the backhaul link (wired, Uu interface of the cellular network, 2G / 3G / Wi...
