Example Embodiment
[0045] Example 1:
[0046] refer to figure 1 and Figure 4 As shown, a roadside device (also called a roadside unit, RSU) provided in 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-range communication, and configure each of the radio frequency units 2 according to the configuration information, configure each radio frequency unit 2 into different channels and frequencies respectively, and maintain the communication with each radio frequency unit 2. The 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 on-board unit, OBU) 3 using the configured channel and frequency.
[0049] The roadside equipment RSU provided by the embodiment of the present invention includes a host computer and several radio frequency units...
Example Embodiment
[0072] Example 2:
[0073] refer to Figure 1-Figure 4 As shown, an embodiment of the present invention further provides a system configuration method for the RSU, including:
[0074] The host 1 of the RSU acquires the configuration information of the system about short-range communication, and configures the radio frequency unit 2 according to the configuration information, configures each radio frequency unit 2 into different channels and frequencies, and maintains the communication link with each radio frequency unit 2 ;
[0075] The radio frequency unit 2 of the RSU broadcasts system information and communicates with the OBU 3 according to the configured channel and frequency.
[0076] In an embodiment, in the system configuration method of the RSU, the host of the RSU obtains the configuration information about the short-range communication of the system, which specifically includes: the host 1 obtains the locally stored configuration information about the short-range c...
Example Embodiment
[0085] Example 3:
[0086] refer to Figure 1-Figure 4 As shown, the embodiment of the present invention provides a 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 information transmission, performs data broadcasting, and transmits all frequency information, control information, encryption 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 a...
