Background

: (Electronic Toll Collection) Electronic Toll Collection (ETC) system is the most advanced way and bridge charging mode in the world at present, deducts the amount of money on a user card or carries out background settlement processing with a bank by using a computer networking technology through the special short-range microwave communication between a vehicle-mounted Electronic tag arranged on a vehicle windshield and a microwave antenna on an ETC lane of a Toll station, the ETC is an advanced electronic toll collection technology, is mainly applied to ramp entrances and exits and main line sign stations at present, and is an ETC application mode under a closed highway toll scene.

: the On board Unit is an abbreviation of an On board Unit, and the interpretation is that the microwave device communicates with an RSU (remote Short Range communication) by adopting a DSRC (dedicated Short Range communication) technology, in an ETC system, an OBU is placed On a vehicle, roadside-Road Side units (RSU-Road Side units) are erected On the roadside, the OBU and the RSU communicate with each other through microwaves when the vehicle passes through the RSU at a high speed.

Monolithic OBU: the differences between the one-piece OBU and the previous generation two-piece OBU include the following differences: the monolithic OBU simplifies hardware resources, optimizes a 5.8G communication system and can more efficiently complete a high-speed transaction process; when the OBU does not detect the 5.8G signal, the OBU module is in a dormant state, when the OBU detects the 5.8G signal, the monolithic OBU is activated, the radio frequency identification unit of the OBU receives the 5.8G signal from the RSU, and the signal is transmitted to the main control unit to complete the transaction after being analyzed by the encryption module in the OBU; the single-chip OBU is internally provided with no card reader, the user information is stored in the ESAM security structure, and when the single-chip OBU interacts with the RSU, the information in the ESAM security structure is directly read, so that the transaction fee deduction can be completed, the card reading time is greatly saved, and the problem of card compatibility is effectively solved.

: the ETC system is installed On the roadside and is a device for realizing vehicle identity recognition and electronic toll collection by adopting DSRC (differentiated Short Range communication) technology and communicating with an On Board Unit (OBU).

: the wireless carrier communication technology using the frequency bandwidth of more than 1GHz does not adopt a sinusoidal carrier, but utilizes nanosecond-level non-sinusoidal wave narrow pulses to transmit data, so that the occupied frequency spectrum range is large, although wireless communication is used, the data transmission rate can reach more than several hundred megabits per second, signals can be transmitted over a very wide bandwidth by using the UWB technology, and the regulations of the Federal Communications Commission (FCC) on the UWB technology are as follows: and the bandwidth of more than 500MHz is occupied in the frequency band of 3.1-10.6 GHz.

When a vehicle is about to enter a parking lot, the OBU interacts with the parking lot RSU information, ESAM information (information such as OBUID, contract serial number, license plate number, vehicle type, identity card and the like) in the OBU is read, the information is recorded and transmitted to a background control center, a marker post lifts a rod, the vehicle drives into the parking lot, when the vehicle is about to drive out of the parking lot, the parking lot RSU interacts with the OBU information again, the background control center calculates the amount of consumption, and the expense is directly deducted from the OBU.

In order to solve the above technical problem, the present application provides a novel one-chip OBU including a UWB positioning structure applied to a parking lot.
