Description
Technical field
The utility model is used for the electronic charging system without parking field of intelligent transportation system, is concretely exactly that one kind is carried
The system of ETC board units transaction success rate high.
Background technology
Electronic charging system without parking (Electronic Toll collection, abbreviation ETC) is logical with special short distance
Letter technology (Dedicated Short-Range Communication, abbreviation DSRC) is leading, realizes vehicle non-parking charge
Intelligent transportation system.System is by roadside unit (Road Side Unit, abbreviation RSU) and board units (On Board
Unit, abbreviation OBU) between dedicated link interaction, realize the purpose of automatic charging.In recent years, with the height of Chinese national economy
Speed development, automobile enters huge numbers of families, but this also causes to generate a series of problem.Annual Labor Day, 11
Golden week can be nearly all got lodged on expressway, wherein a critically important reason is just because manual toll collection (MTC) inefficiency,
Cause vehicle pass-through slow.For MTC, electronic charging system without parking (ETC) has full-automatic, high speed convenient, non-existing
Gold transaction, it is safe the features such as, be solve this problem an effective method.
China's roadside unit, board units manufacturer are numerous, and each producer's technology is uneven, roadside unit (RSU)
Used as a part very crucial in electronic charging system without parking, its importance is self-evident, but current roadside unit
Emission of radio frequency signals module and rf signal reception module are not differentiated between mostly, sent, are received by the completion of same radio-frequency module,
Solve monkey chatter, with car interference, call out and do not wake up the aspect such as board units and also there is many deficiencies；Board units (OBU) factory
Family's technology is also irregular polishing, and this is also the major reason for causing ETC vehicle pass-throughs rate not up to perfect condition.
In the prior art, sending and receiving for radiofrequency signal completes by same antenna array element, height transaction success rate
It is current with vehicle high-speed to be difficult to get both.At present major part ETC system in order to avoid monkey chatter, disturbed with car the problems such as hair
It is raw, the overlay area of RSU signals is generally set to 6.0x3.0m~8.0x3.2m, although this solves this to a certain extent
A little problems, but when vehicle quickly through when, will cause to call out do not wake up board units or midway Fail Transaction, influenceed car body to test,
Unnecessary dispute even can be caused.
So being badly in need of developing a kind of on the premise of vehicle pass-through rate is not influenceed at present, the system for solving these problems.
Utility model content
The purpose of this utility model is to improve the transaction success rate of ETC board units.
To achieve these goals, the system is received by mesh the hair of radiofrequency signal by a kind of roadside unit technology of innovation
Preceding single radio-frequency module switchs to two antenna array units, i.e. launching antenna array column unit and receiving antenna array column unit.
The system is made up of launching antenna array column unit, two antenna array units of receiving antenna array column unit.Radio frequency is believed
Number transmitting and receiving no longer completed by single radio-frequency module, but completed jointly by transmitter unit, receiving unit, to improve
The transaction success rate of ETC board units.
Launching antenna array column unit sets up special interactive link for launching radiofrequency signal with board units, but is not used in
The radiofrequency signal that board units are replied is received, its signal intensity can be adjusted by radio-frequency modulations module, and its signal is covered
Signal coverage areas of the region more than receiving antenna array column unit.
Receiving antenna array column unit is used to receive the radiofrequency signal of board units reply, and then completes whole transaction.Receive
Antenna array unit can keep interacting, until handing over this board units always after the radiofrequency signal for receiving board units reply
Release trade link is readily accomplished, receiving antenna array column unit just can the next board units for only entering transaction area of reception processing time
Multiple radiofrequency signal.
The beneficial effects of the utility model are：Transmitting antenna array cell signal overlay area is more than receiving antenna array list
The signal coverage areas of unit, increase the overall area of coverage of radiofrequency signal, are conducive to waking up board units in advance；Reception antenna
The signal coverage areas of array element are less than the signal coverage areas of launching antenna array column unit, and its radiofrequency signal more collects neutralization
Stabilization；Radio-frequency modulations module can be adjusted to the signal intensity of two antenna array units.ETC board units are improved with this
Transaction success rate.
