License Plate Recognition Parking Access Control System ANPR Software

1 Booth- This structure is the working place for parking attendant . They can manage entering vehicles and collecting  parking fee from leaving vehicles here(if pay with automatic payment station,there may be not booth at the exit)

2 Island- Structure for installation booth, barrier and LPR device.

3 Barrier- In order to control entering vehicles efficiently, barrier is installed in heavy traffic area to control  vehicle access,  at entrance/exit.

4 LPR device- LPR device takes images of entering/leaving vehicles with high-definition mega pixel camera and it recognizes plate number automatically then access control/manage vehicles

5 LPR display unit- Install and link with LPR device, display recognized vehicles' information and note driver information(option)

6 Loop- Loop coil is laid at entry/exit of parking lot.The device receive high frequency signal current from vehicle detector and make a magnetic field near loop coil. Once vehicle pass this field, send impedance changes to detector and convert voltage and amplify them and send detect information signal to camera or barrier gate

Straight lane is the best type to recognize plate number. and ANPR camera can take an image of max.3.5m width. If ANPR device is installed more than 3.5m road width, vehicle guide equipment(ex.Elastic rod.signboard,etc.) should be installed.In case of installation speed bump the size of bump must be road width. If speed bump size is smaller than road width,driver would not approach straight way to avoid speed bump, then ANPR camera cannot capture clear and accurate image for recognition,then will affect the ANPR accuracy.
