Problems solved by technology

[0002] With the development of intelligent traffic management and Internet of Vehicles technology, the roadside equipment (or Road Side Unit, RSU) and vehicle terminal (or Vehicle Unit, On Board Unit, OBU) in the intelligent traffic management system adopt Short-distance communication is used to communicate, realize vehicle identification, electronic toll deduction, realize non-parking, free card collection, and establish unattended vehicle passages. Currently, the RSU of short-distance communication has a single channel, and most of them can only realize RSU. One-to-one communication with OBU alone, even if the RSU can communicate with several OBUs at the same time, the capacity is very limited, which affects the efficiency of system information communication and is prone to communication errors

Embodiment 1

[0046] refer to figure 1 and Figure 4 As shown, a roadside device (also called a roadside unit, RSU) provided by Embodiment 1 of the present invention includes a host 1 and a radio frequency unit 2;

[0047] The host 1 is used to obtain the configuration information of the system about short-distance communication, and configure each radio frequency unit 2 according to the configuration message, configure each radio frequency unit 2 to a different channel and frequency, and maintain the same A communication link of the radio frequency unit 2;

[0048]The radio frequency unit 2 is used for broadcasting system information and communicating with an on-board terminal (also called an on-board unit, OBU) 3 using configured channels and frequencies.

[0049] The roadside equipment RSU provided by the embodiment of the present invention includes a host and several radio frequency units. The host configures each radio frequency unit, effectively realizing the design of multi-channel...

Embodiment 2

[0073] refer to Figure 1-Figure 4 As shown, the embodiment of the present invention also provides a system configuration method of the RSU, including:

[0074] The host 1 of the RSU obtains the configuration information of the system about short-distance communication, and configures the radio frequency unit 2 according to the configuration information, configures each radio frequency unit 2 to a different channel and frequency, and maintains a communication link with each radio frequency unit 2 ;

[0075] The radio frequency unit 2 of the RSU broadcasts system information and communicates with the OBU3 according to the configured channel and frequency.

[0076] In one embodiment, the system configuration method of the RSU, the host of the RSU acquires the configuration information about the short-distance communication of the system, which specifically includes: the host 1 acquires the locally stored configuration information about the short-distance communication Or recei...

Embodiment 3

[0086] refer to Figure 1-Figure 4 As shown, the embodiment of the present invention provides the communication process between the roadside equipment RSU and the vehicle-mounted terminal OBU, which may include the following steps:

[0087] S1: After the radio frequency unit 2 of the RSU completes the channel and frequency configuration according to the configuration information of the host 1, it starts to send information, broadcast data, and send information including all frequency point information, control information, encrypted information, and communication codes through its control channel. system information;

[0088] S2: OBU3 enters the coverage of the RSU and receives the broadcast information of the control channel;

[0089] S3: OBU3 will calculate the received information according to the preset rules, and then set OBU3 to the required communication frequency and channel;

[0090] Specifically, it may be that the OBU3 determines the frequency point according to t...

Abstract

The invention discloses a roadside device RSU, comprising a host and radio frequency units, wherein host is configured to acquire configuration information about short-range communication of the system, configure each radio frequency unit according to a configuration message, respectively configure different channels and frequencies for the the radio frequency units, and maintain communication links with the the radio frequency units; and the the radio frequency units are configured to broadcast system information and communicate with an OBU by using the configured channels and frequencies. The roadside device RSU disclosed by the invention solves the problems of single RSU channel, low communication efficiency and poor communication security reliability in the prior art. The invention also discloses a system configuration method of the roadside device RSU.

Description

technical field [0001] The invention relates to a roadside equipment RSU and a system configuration method thereof. Background technique [0002] With the development of intelligent traffic management and Internet of Vehicles technology, the roadside equipment (or Road Side Unit, RSU) and vehicle terminal (or Vehicle Unit, On Board Unit, OBU) in the intelligent traffic management system adopt Short-distance communication is used to communicate, realize vehicle identification, electronic toll deduction, realize non-parking, free card collection, and establish unattended vehicle passages. Currently, the RSU of short-distance communication has a single channel, and most of them can only realize RSU. One-to-one communication with OBU alone, even if the RSU can communicate with several OBUs at the same time, the capacity is very limited, which affects the efficiency of system information communication and is prone to communication errors. [0003] Due to the large number of vehi...
