Abstract

The invention discloses a method for communication between a vehicular radio-frequency identification card and a wireless base station. The wireless base station is provided with a wake-up channel, a field positioning channel and a plurality of data channels, which work independently; the vehicular radio-frequency identification card is provided with a wake-up channel, a field positioning channeland data channels, which correspond to each channel of the wireless base station; the wake-up channel of the wireless base station transmits a wake-up code, and the vehicular radio-frequency identification card receives the wake-up code by the wake-up channel of the vehicular radio-frequency identification card; the field positioning channel of the wireless base station transmits a field positioning code, the vehicular radio-frequency identification card receives the field positioning code by the field positioning channel of the vehicular radio-frequency identification card, and one data channel of the vehicular radio-frequency identification card reports data to the corresponding data channel of the wireless base station after the field positioning channel of the vehicular radio-frequency identification card receives the field positioning code. Because each channel of the wireless base station works independently, the vehicular radio-frequency identification card selects one data channel to report the data, so that communication information between the vehicular radio-frequency identification card and the wireless base station is not easy to lose, and the anti-jamming capability is high.

Description

Technical field

[0001] The present invention relates to a wireless communication method, in particular to a communication method for radio frequency communication between a wireless base station and a vehicle-mounted radio frequency identification card. common places. Background technique

[0002] Radio frequency automatic identification non-stop toll collection system (ETC) is the most advanced road and bridge toll collection method at present. Through the short-range communication between the electronic card installed on the windshield of the vehicle and the wireless base station installed on the lane of the toll station, the computer networking technology is used to carry out background settlement processing with the bank, so that the vehicle can pass through the road and bridge toll station without stopping. purpose of payment.

[0003] However, when the existing ETC is applied to ports, ports, bonded areas and other places where the entry and exit vehicle passages are...
