ETC vehicle-mounted unit multi-scene application method and device based on intelligent TF card

Abstract

The invention relates to an ETC vehicle-mounted unit multi-scene application method and device based on an intelligent TF card. The method includes the steps that the intelligent TF card is used as a safe storage module used for identifying feature data information of different application scenes, a TF card slot is additionally formed in an ETC vehicle-mounted unit, and a processing assembly for identifying and processing the data information is additionally arranged on an ETC lane control system. The device comprises the ETC vehicle-mounted unit arranged on windshield glass of a vehicle and matched with the ETC lane control system and the intelligent TF card connected with the ETC vehicle-mounted unit, the ETC vehicle-mounted unit comprises a main control chip U1, a liquid crystal displayer, a transmitter with a transmitting antenna, a receiver with a receiving antenna, a tamper device, an electrically erasable programmable read-only memory (EEPROM), a power voltage detection circuit, an electricity-saving control circuit and a battery, the main control chip U1 is connected with an intelligent TF card slot U2, the intelligent TF card is inserted into the intelligent TF card slot U2, and the intelligent TF card communicates with the main chip through DOUT, DIN and SCK pins in a linking mode. The ETC vehicle-mounted unit multi-scene application method and device are simple, feasible, convenient to use and easy to popularize and multi-scene application of the ETC vehicle-mounted device is achieved.

Description

technical field [0001] The invention relates to a multi-scenario application method and device for an ETC vehicle-mounted unit, in particular to a multi-scene application method and device for an ETC vehicle-mounted unit based on a smart TF card. Background technique [0002] The non-stop toll collection system ETC (Electronic Toll Collection) is currently the most advanced road and bridge toll collection method in the world. The system mainly uses automatic vehicle identification (AVI) technology to communicate and exchange information with the roadside unit (RSU) on the ETC lane of the toll station and the on-board unit (0BU) installed on the windshield of the vehicle to achieve Automatic recognition of the vehicle, and automatically deduct the toll from the user's special account, so as to realize automatic charging. The system is mainly composed of a front-end and a back-end. The front-end includes a lane control system, RSU, OBU and other auxiliary electronic facilitie...

AI Technical Summary

Problems solved by technology

[0004] However, the current mainstream ETC system generally only supports non-stop charging for one application scenario at the same time. The community parking lot of the system cannot be used, because the ETC system of the community parking lot cannot recognize the ETC vehicle-mounted unit for the highway on the car

This has an adverse effect on the application of the ETC system to multiple scenarios
