Description
Technical field
The invention belongs to public transport field, is related to a kind of electric automobile management of leasing method based on iris recognition and is
System.
Background technology
Automobile is the essential vehicles of modern.Compared with orthodox car, electric automobile has energy-conserving and environment-protective, energy
The features such as source weighting prediction, it will not only bring exhaust emission, moreover it is possible to solve the problems, such as night city electric energy surplus.But at present
The technology and its auxiliary facility of electric automobile are not perfect, many consumers purchase when exist it is all scrupulous, therefore lease mould
Formula is become to promote the important means of electric automobile.
Electric automobile lease, which has, meets that common people's short distance trip requirements, reduction are private using electric automobile cost, reduction machine
Motor-car recoverable amount, alleviate the advantages that environment and Pressure on Energy.Networking is realized between vehicle, citizen can be in any one lease net
Point is rented or gives back electric automobile, and handles the formalities such as lease payment, move back expense.The utilization rate of electric automobile is improved, is led to
The problems such as crossing unified management, to also solve private car maintaining costly, and frequency of use is low, parking is difficult, meet green,
The new life trip mode of low-carbon, health.
But current electric automobile lease relies primarily on cell phone application, RFID card is leased, if RFID card loss,
Mobile phone out of power, just occur that user can not hire a car before card or charging is mended, or RFID card is picked up the phenomenon hired a car by other people.
This reflects current system of hiring a car, and also exists and opens card, mends the artificial link blocked, and vehicle None- identified user's identity
Problem.It can be seen that, it is necessary to be improved to the equipment of electric automobile, its intelligent level is improved.
The content of the invention
To solve the above problems, it is inconvenient to make up existing electric automobile lease it is an object of the invention to provide one kind
The problems such as, the electric automobile management of leasing method and system based on iris recognition.
To achieve the above object, the technical scheme is that the electric automobile management of leasing method based on iris recognition,
Comprise the following steps：
Eye alignment is located to the iris identification equipment of shield glass, starts IMAQ key, digital camera
Eye image is shot, output digital image signal is to processing unit；
Processing unit record starts the time T used in collection key from closing of the door to user；
The image collected is transmitted to assessment unit by processing unit, and the preliminary quality that assessment unit carries out image is assessed, commented
Estimate the basic parameter of image；
If image is unsatisfactory for quality requirement, abandons and prompt to reacquire lower piece image；
If image meets to require, processing unit carries out feature extraction and the coding of iris to the image；
Processing unit transmits the iris code of extraction to back-stage management center together with time T；
The characteristic value received is compared in database at back-stage management center；
Match unsuccessful, then exit；
The match is successful, and back-stage management judges the request of user centrally through the rental status to time T and the car；
If request of hiring a car, then unlocking signal is sent to processing unit, lock control unit unlocks the electric automobile car door
For a period of time, if user opens car door within the time of unblock, back-stage management center is bound the user profile and vehicle ID, opened
Beginning charging, and pass signal of hiring a car is sent to processing unit, processing unit change vehicle-state is in lease；
If unlocking request, then unlocking signal is sent to processing unit, lock control unit opens car door；
Asked if returning the car, then whether back-stage management Spot detection vehicle is located at as defined in operation in parking area；
If not in defined parking area, prompt to return the car and exit again；
If in defined parking area, locking signal is sent to processing unit, it is electronic that lock control unit locks this
Automobile, close the account, unbind user profile and vehicle ID, pass signal of returning the car is sent to processing unit after success, processing is single
Member change vehicle-state is completed to return the car not lease.
Preferably, described the match is successful, and back-stage management judges user's centrally through the rental status to time T and the car
Request, T is more than a period of time, and vehicle-state is can lease, then be request of hiring a car；T is more than a period of time, and vehicle-state is
Then it is unlocking request in lease；T is less than a period of time, then is request of returning the car.
Preferably, the digital camera shooting eye image, the automatic light-supplementing in the case where light is bad.
Preferably, described image sensor is CMOS formulas.
Preferably, the processing unit is also connected with display unit, and real-time display shooting picture, text prompt user clap again
Take the photograph, word displaying iris recognition result, vehicle-state.
Preferably, it is described whole closing of the doors for a period of time after, if user is without any operation, lock control unit meeting
Automatically car door is locked.
Corresponding with the above method, present invention also offers a kind of electric automobile management of leasing system based on iris recognition
System, including collecting unit, assessment unit, processing unit, display unit, lock control unit, radio communication unit and backstage are managed
Reason center, wherein, the processing unit and collecting unit, assessment unit, display unit, lock control unit and wireless telecommunications list
Member connects respectively；
The collecting unit, including camera, imaging sensor, camera are used to shoot iris picture, imaging sensor
Optical imagery is converted into electronic signal and exported to processing unit；
The assessment unit, the eye image collected by processing unit transmission collecting unit, is carried out just to eye image
Quality evaluation is walked, judges whether to obtain effective eye image, it is single to processing if not collecting effective eye image
First feeding back unsuccessful signal, processing unit send signal to display unit, and display unit prompting is re-shoot；
The processing unit extracts the characteristic value of iris-encoding according to the qualified eye image collected, records from whole cars
Door is closed to the time T used in user's triggering IMAQ key, and the characteristic value of extraction and time T are passed through into radio communication unit
Get forwarded to back-stage management center；
The back-stage management center is connected with the radio communication unit, including at least matching module and comparing module, is received
To after the characteristic value of radio communication unit transmission, comparing module compares it in database, and matching module is according to comparison
As a result differential responses are made；
