Row test obtains, is tested, is realized to this using license plate of the system provided in this programme to different regions in experiment
Information of vehicles, load-carrying, stroke, mileage, speed, payment amount of money are monitored detection, and actual measurement condition, which is worked as, misses the stop speed in 15KM/h
It is interior, shooting incidence angle in 30 ° when, recognition result is correct, only when speed 35KM/h and shooting incidence angle at 45 ° when,
Produce it is primary it is unidentified go out the case where, and when testing for second, with same experimental conditions, it is dynamic that system completes correct identification
Make, is experimentally confirmed and misses the stop passage speed, i.e. artificial channel 5KM/h in existing automobile, the channel ETC 20KM/h, this system
It is able to carry out and accurately identifies.
Compared with existing charging system of missing the stop, existing charging system of missing the stop is unable to reach this to the discrimination of lorry
The discrimination of scheme, unidentified, false recognition rate is more than this system, while existing charging system of missing the stop believes vehicle
The information such as breath, driving information, loading state can not count, and with existing charging system of missing the stop, can not hand over for intelligence from now on
Logical realization provides basis.

Controller 5, which can choose, not to be started, and staff can carry out trial inspection, cross-check information at this time, and transfer at relevant departments
Reason, but no matter at this time whether driveway controller 5 starts, communication signal lamp 51 should all variable condition, issue impassable police
Show information.
Further, in step 4, the induction region that vehicle is driven out to includes 111 region of main induction device and/or secondary sense
Answer the induction region of device 112, driveway controller 5 controls railing and closes, communication signal lamp 51 issues that no through traffic signal.Work as goods
Car body amount is excessive, when vehicle body is longer, then major and minor sensing device 111,112 is needed to be cooperated to extend induction region, such energy
Enough vehicle body is avoided to advance in induction region, but since length is too long, sensing device can not sense in time whether lorry sails out of
Induction region avoids lorry headstock in this way and has run out charge hilllock, but sensing device 11 does not monitor that lorry is driven out to also.
Further, it includes " extension " word shape information and " extension " word stroke shape information that information is compared in database 6.
" extension " word shape information and " extension " word stroke shape information are for the extremely important of identification lorry, in existing identification system of taking pictures
There is one to be responsible for the database that storage compares comparison information in system, the comparison information usually stored in the database is each province
Part abbreviation, letter and number, such as " capital, saliva, Ji, Hunan, Anhui, Jiangxi, A, B, C, 1,2,3 " etc., in identification process, letter and
The identification of number is very high, but accuracy rate is not fully up to expectations in the identification of province abbreviation, in technological improvement later,
It sets the abbreviation of the province in the province region preferentially to compare object, this also allows for monitoring system in the mistake of identification comparison
Preferentially " extension " word is referred to as compared with province in journey.
For example: when to be that " Ji A12345 extensions " at it drives into Guangxi domestic for its license plate number of lorry, setting is in Guangxi
Charging system be easy to that the abbreviation " osmanthus " that word is identified as Guangxi will be hung, to cause largely to misidentify, influencing to charge hilllock just
Often work, in addition font composed structure is similar also easily identifies mistake, such as the abbreviation in Shaanxi Province: " Shan ", Hainan Province: " fine jade ",
Zhejiang Province: the fonts such as " Zhejiang " all easily identify mistake；It " is hung " simultaneously in identification, is also easy to obscure with " E ", " F ".
And lorry car owner, which would generally amplify license plate number, to be written on the car body of the tailstock so that it is convenient to the bat of video monitoring
The hull back taken the photograph, but have many vehicles be not it is smooth, the font of writing can be with the protuberance of car body out-of-flatness or recessed
It falls into and forms the patterns such as turnover, this, which is also just affected, writes content on the car body pattern under normality, the change of font can not be presented
Shape also results in the misrecognition of video monitoring system, is taken by this programme by " extension " word shape information and " extension " word stroke shape
The means that shape information is compared respectively can obtain the synthesis result after Chinese character pattern and stroke compare after polynary comparison,
The accuracy rate for substantially increasing video monitoring enables this system by optimizing video input apparatus 13 and database 6
Enough accomplish that 95% or more tends to 100% superelevation discrimination.
Meanwhile the transmission chip used in the Data Encryption Transmission module 21 in this system uses the core for LORA chip
Piece is advantageous in that: the data that cart flows down are not getting lines crossed, strong antijamming capability, are transmitting and stablize, is energy saving, in the charge usual vehicle of Gang Chu
Stream is intensive, this also allow for being easy to happen when a large amount of wireless transmission signals are transmitted signal get lines crossed, receiver signal congestion
The problems such as, and when by charge hilllock, be capable of smooth hilllock of crossing to ensure, the stability of signal transmission be also it is vital, when
Sometimes without or at times strong and at other times weak intermittent signal easily cause identification to make mistakes, this can cause vehicle can not normal smooth mistake
Hilllock, it will cause traffic congestions, or even cause traffic accident, and for goods stock, the service time is not fixed, this
Also just needing on-vehicle equipment should be that cruising ability is strong, therefore the special communication chip for using the chip as module herein.
