Integrated single-chip vehicle-mounted equipment

Abstract

The invention provides integrated single-chip vehicle-mounted equipment, and the equipment is provided with a power module, a main control chip, a first communication module and a double-interface card module; the power module is connected with the main control chip and the first communication module, and the main control chip is connected with the first communication module and the double-interface card module; when approaching the hand-held card reading device, an antenna in the dual-interface card module is coupled to obtain electric energy, establishes connection with the handheld card reading equipment, and executes corresponding operation on a user card in the dual-interface card module according to an operation instruction sent by the handheld card reading equipment; when leaving from the handheld card reading equipment, the dual-interface card module generates an interrupt signal to trigger the main control chip to read the information of the user card again. The user card chipis integrated in the vehicle-mounted equipment; when transaction with the ETC system fails, the handheld card reading equipment is used for communicating with the vehicle-mounted equipment to complete transaction, so the size of the vehicle-mounted equipment can be further reduced, the user experience is improved, and the driving risk is reduced.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of road charging, and in particular to an integrated single-chip vehicle-mounted device. Background technique [0002] With the development of the industry, the number of vehicle-mounted devices currently sold through banking channels is huge, and the proportion of debit cards used is getting higher and higher. [0003] At present, the electronic toll collection system (Electronic Toll Collection, ETC) in China uses a double-chip (On Board Unit, OBU) vehicle-mounted device, also called a double-chip electronic label, which supports User card reading and writing function, the user card is inserted into the electronic tag as the medium of non-cash payment. The so-called double-chip electronic tag, the first chip refers to a 5.8GHz wake-up, sending and receiving communication, dedicated short-range communication technology (Dedicated Short Range Communications, DSRC) protocol analysis...
