Description
Technical field
The utility model relates to the vehicle-carrying communication technical field, particularly relates to a kind of car plate monitoring device and a kind of Vehicle License Plate Recognition System.
Background technology
Fake-licensed car is commonly called as clone's car, refers to by forging or illegally extract the vehicle that the formalities such as other number plate of vehicle and driving license are set out on a journey and travelled.The harm of fake-licensed car mainly contains: seriously hinder public security organ to the management and control of public safety, make social labile factor, upset the transport market management order, upset the economic order of country, the true car owner's of infringement legitimate rights and interests etc.
Tradition is for monitoring and the identification of fake-licensed car, mainly by following dual mode:
One, rely on the modes such as human eye and feel touch to monitor and identify.This mode relies on related personnel's experience and subjective supposition, lacks mode accurately and effectively, and investigation efficient is low.And in night and boisterous situation, can't identify vehicle photographic timely and effectively, do not reach and check purpose convenient, car plate management accurately and reliably;
Two, detect force value between car plate and license bracket by pressure transducer, thereby whether monitoring and identification car plate there are false license plates paster or deck car plate.Yet the dependence pressure transducer detects the support relation between car plate and support, may have following deficiency:
1), when Sensitivity in Pressure Sensors is higher, artificial be not intended to collision and may cause and misreads data upload.Because vehicle is in the middle of reality use or servicing operations, driver or Motor Maintenance personnel may touch car plate in the middle of being not intended to, pressure transducer on this moment car plate monitoring device can think that vehicle license plate reequips privately by mistake, and this situation is arrived vehicle management center by Internet Transmission, thereby bring unnecessary trouble to the related personnel;
2), when Sensitivity in Pressure Sensors is low, can't effectively identify the false license plates paster that is posted in above car plate, deck car plate etc.As the fake-licensed car user when the lighter false license plates paster of some weight, CD or other illegal overcover are puted up in the car plate front, pressure transducer can't effectively detect overcover, and vehicle management center can't in time be known the violations of law such as fake-licensed car this moment.
As seen, traditional for fake-licensed car monitoring and recognition method in more or less can have some problems, so the task of top priority is to provide a kind of more efficiently car plate monitoring and recognition method.
The utility model content
Based on this, the utility model provides a kind of car plate monitoring device and Vehicle License Plate Recognition System, can effectively monitor and identify car plate.
For achieving the above object, the utility model adopts following technical scheme:
A kind of car plate monitoring device comprises: spring, pressure sheet metal, support member, control circuit, switch; Described control circuit is fixed on car plate; Described switch series is associated on described control circuit and is off-state; Described support member is fixed on described car plate; Described pressure sheet metal is arranged between described support member and described spring.
A kind of Vehicle License Plate Recognition System comprises: car plate pick-up unit and above-mentioned car plate monitoring device; Described car plate pick-up unit is arranged on the gate cross bar, and described car plate monitoring device is arranged on vehicle body.
Can be found out by above scheme, car plate monitoring device of the present utility model and Vehicle License Plate Recognition System, when car plate normally uses, the pressure-acting on support member on the pressure sheet metal, this moment spring contraction, the formation of pressure sheet metal and control circuit is opened circuit; After car plate was dismantled privately, the pressure of support member no longer acted on the pressure sheet metal, at this moment spring reinstatement, and the pressure sheet metal will be connected with control circuit by switch, and the control circuit conducting forms the loop.After in case the control circuit conducting forms the loop, the car plate monitoring device will record car plate dismounting situation, the car plate pick-up unit obtains to send the car plate data to vehicle management center after license board information and car plate dismounting record, by vehicle management center, the truth of vehicle license plate is differentiated.Compared with prior art, the utlity model has following beneficial effect:
One, stability is high.The GPRS networking module that car plate recognition detection process of the present utility model does not rely on vehicle carries out data transmission, has avoided having some setbacks or the factor such as artificial interference causes more news of license board information due to network data transmission and upgrade more secure;
Two, design is more reasonable.Avoided adopts pressure sensor to monitor and identify car plate in the utility model, therefore design is more reasonable, can not cause maloperation;
Three, the recognition capability to car plate is stronger.The utility model can effectively be monitored car plate and be changed, and prevents the dismounting privately of car plate, finds accurately the deck vehicle;
Four, obtain data more timely.The utility model realized vehicle management center from original passive type obtain license board information to the transformation of active detecting license board information, avoided the phenomenon that lags behind because monitoring the untimely management that causes.
