A kind of anti-escape charging method of ETC
Technical field
The present invention relates to the vehicle information recognition methods of ETC a kind of, belong to intelligent transportation field, more particularly to one kind
The anti-escape charging method of ETC.
Background technique
Intelligent transportation is the developing direction of future transportation system, and under this trend, ETC system is used widely.
ETC system includes background system, driveway controller, roadside unit RSU, and is arranged by the lane ETC.When vehicle passes through charge station
When, ETC system and the on board unit OBU being arranged on vehicle carry out information exchange, realize the identification of information of vehicles, determine the vehicle
Vehicle, and the corresponding expense of the vehicle is deducted from the account of the vehicle, to realize non-parking charge.
The vehicle that can be passed through in the lane ETC is generally divided into 4 classes: it is one kind that wherein 7 below, and 8-19 are two
Class, 20-39 are three classes, and 40 the above are four classes, and a kind of vehicle charge is minimum, four class vehicles charge highest.With ETC skill
The development of art, various types of goods stocks will also be able to achieve non-parking charge, to improve the efficiency of highway.
Cart small tenon is that one kind evades pass cost behavior, i.e., will actually handle the vehicle of ETC, is changed intentionally in the data of submission
To reduce corresponding highway charging standard, to achieve the purpose that few friendship pass cost compared with carriage type.It is main at present
The anti-fee evasion measure of ETC is mainly audit in thing, afterwards two kinds of approach of inspection.Audited in thing, be ETC handle personnel audit user mention
Whether the vehicle data of friendship is consistent with field vehicle, and requires to be installed on to handle according to traffic criteria by board unit OBU in person
On vehicle.Subsequent inspection, is that the information of vehicles of the information of vehicles and traffic police's system provided when user to be handled to ETC compares, with
This finds whether vehicle has the fee evasions behavior such as cart small tenon.
Above two kinds of modes can not fundamentally prevent the fee evasions problem such as cart small tenon, and reason is: firstly, ETC work
It is possible in the presence of cheating to make personnel, staff is not if installed on board unit OBU by traffic criteria requirement, to make car owner can be with thing
On board unit OBU shifting is attached on other vehicles afterwards, causes cart small tenon;Secondly, ETC has realized on national network charge at present,
Vehicle can open ETC business in any networking province, but the anti-fee evasion system of matched ETC is not set up, each province ETC
Publisher can only according in this province system vehicle and traffic information judge vehicle with the presence or absence of cart small tenon fee evasion problem.If
One vehicle is not current in the province that it handles ETC, is difficult to be found there are problems that cart small tenon.

Optical port and second laser mouth, first laser mouth and second laser mouth both face towards the lane ETC, first laser mouth and second laser opening's edge
ETC lane length direction arrangement.The utility model passes through scanning laser sensor, license plate recognition device and driveway controller reconstruct
The three-D profile of vehicle carries out precise model identification, even if cart has filled the OBU of trolley, not due to information of vehicles and OBU information
Meet, cart will be unable to pass through, and prevent fee evasion behavior of the vehicle on the lane ETC, safeguard the interests of highway owner, maintain
The order of communication and transport market.
As Chinese patent (105488855 A of Authorization Notice No. CN) discloses a kind of " efficient drive-in toll system
System ", in addition to ETC card, railing one, railing two, RFID card reader one, RFID card reader two, camera, master controller, showing
Outside display screen, data connecting line, also have Zigbee submodule, Zigbee main module, pressure sensor one, pressure sensor two,
