Abstract

The invention relates to a 5.8GHz DSRC-based path recognition wireless communication method, an identification antenna and an identification terminal. The method is applied to communication between the identification antenna and the identification terminal. At the identification antenna side, the method includes the following steps that: BST frames are broadcasted, wherein the BST frames contain path information; and VST frames from the identification terminal are received, terminal IDs contained in the VST frames are recorded, and a recently received terminal ID is utilized to update an original terminal ID in a link release domain. At the identification terminal side, the method includes the following steps that: the BST frames are received, wake-up signals are obtained, the identification terminal is waken up to enter a receiving mode; the VST frames are transmitted to the identification antenna, wherein the VST frames contain the terminal ID of the identification terminal; a terminal ID contained in the link release domain of the BST frames is tentatively matched with the terminal ID of the identification terminal, when the terminal ID contained in the link release domain of the BST frames is successfully matched with the terminal ID of the identification terminal, the identification terminal quits from the receiving mode and enters a sleep mode; and the path information is stored in the storage unit of the identification terminal. The 5.8GHz DSRC-based path recognition wireless communication method of the invention has the advantages of high path identification efficiency, low power consumption and short path identification time.

Description

technical field [0001] The present invention relates to the field of intelligent transportation, and more specifically, relates to a 5.8GHz DSRC-based path identification wireless communication method, an identification antenna and an identification terminal. Background technique [0002] With the increasing number of provinces connected to the national network of ETC, the 5.8GHz intelligent transportation dedicated frequency band wireless communication technology has begun to experience explosive growth. The Ministry of Communications also expects that 5.8GHz can carry more intelligent transportation services. As an important part of high-speed intelligence, the high-speed ambiguity path recognition system mainly uses ISM communication technology in the 433MHz frequency band. However, considering that this frequency band is not a dedicated frequency band for intelligent transportation, and other systems interfere seriously, there is an urgent need for a system based on 5.8G...
