ANPRSystem with LPR camera:
Coma license plate recogniton management systemis a high-end digital video using decomposition technique for automated identification plate number of vehicle management system ,temporary vehicle identification rate of more than 95%.this system can be used alone ,without stopping the free flow of parking ,but also with ID/IC card parking system used in combination to achieve the dual plate number+card data authentication multi-layer.The system is currently the most perfect system,stable and reliable.
Suitable forthe parking lot in residential communities, enterprises and institutions, hotels, commercial buildings, government organizations, logistics company, hospitals, villages, shopping markets, and so on.
Parking management system also has following titles:car parking management system, parking control system, parking partner, car parking lot system, car parking device, car parking equipment,car security system, smart parking, intelligent parking system, automated parking management system, auto parking system, automatic parking system, mechanical parking system ,advanced parking system, efficient parking system,RFID/paper ticket(barcode)parking system, middle-distance parking system ,Bluetooth long distance parking system, electronic tag parking system.
For the first five progress (1, 2, 3, 4, 5). There are two actions.
The vehicle arrives at the entrance, press the sensor coil which install underground, then a signal is sent to the camera. They have the corresponding reaction:
The camera: take photo of the vehicle,recognize the license plate number,send a singal to barrier gate
The barrier gate: open
(The hardware like barrier and camera all are controlled by the software –license plate recognition software, so strong recommend to purchase the whole set equipment of system from COMA)
The vehicle enter the parking lot, the barrier gate close automatically.
For the last six progress (6, 7, 8, 9, 10, 11).there are following action:
The vehicle arrives at the exit, press the sensor coil which installed underground, then a signal send to the camera ,it take photos and the information is stored in the software to compare with the entrance information
The software will analyze the compatibility between entrance information with the exit information automatically, to check whether the vehicle have the same license plate number.
There are two kind vehicles cross
One is usually pass (we call it as VIP vehicle)
The other is temporary parking (we call it as time vehicle)
For the VIP vehicle, which should register information such as license plate number that will be stored in the software for the later analysis. When the VIP vehicle passes, the software will compare the information picked up from the photo with the stored information in the software. The barrier gate can open only when the information matching
For the time vehicle, when it passes, the software will analyze the information between entrance and exit to calculate the parking fee.the barrier gate will open for vehicle to leave after paid.
(a) License plate recognition system function:
COMA CML0166-based Automatic Vehicle Identification Management System is an automatic license plate recognition technology to control the number of fixed vehicle access computer management system. The system will identify the technology and advanced digital video images stored in relatively high-speed combination, by computer image processing and discrimination, vehicles entering and leaving the car park access control management. The system is composed of a set of ID parking lot, one microcomputer controller, two special camera, one image processing network card and two sets of the spotlight. Automatic license plate recognition in the management system, the vehicle entrance to the parking lot or by the vehicle detector to detect the vehicle, the trigger system start the camera capture images of vehicles, through the automatic license plate recognition software to capture images of dynamic filtering , cross-boundary enhancement processing to overcome the interference image, improve recognition results. In the dynamic image acquisition to automatically find the location of the license plate and automatically extract a single character images. License plate location and through the direct method, neural networks, vector quantization method and the license plate character recognition OCR matching simulation-based algorithms, artificial neural network based OCR algorithm to arrive at the digital license plate number, software to count not number of databases with the original issue lawful license plate number eleven in contrast, if the same number, the system controller will inform the ID parking lot or open the entrance barrier to allow vehicles into or out of the car after a second vehicle detector automatically shut down when the road barrier.
(b) System software functions and features the system performance features:
1.Using computer control and data processing techniques, high degree of automation, control accuracy. 2.Barrier passage of the vehicle automatically rise and fall, and smashed cars with anti-function. 3.High-speed video surveillance, real-time recording vehicle models, and out of vehicles on the image contrast, effective in preventing theft of vehicles in the parking lot. 4.Reduce management costs, to have access to accurate records of vehicle information can be found. 5.Management computer can achieve real-time monitoring and management computer has an external interface, network scalability. 6.Standard industrial control system architecture can be organized according to different requirements of different user system configuration, convenient and flexible. 7.System management software under WINDOWS environment written in English operation menu display, user-friendly. Each step has a detailed description of the prompt, simple, easy to use. 8.installation, commissioning, maintenance is simple and convenient, easy to replace and repair 9.Normal light (100 ~ 80 lumens) under the conditions of the comprehensive identification of the vehicle not less than 99.9% probability.
Systemsoftware functions and features Programming language:Windows2000 +VS.NET Database:SQLSERVER2000
1. Using the world's most advanced computer simulation control science, with a high degree of automatic and simple to use. 2. Sub-front operation run real-time management software (operator), back office software (management software). 3. Full-friendly interface in English. Chinese menu display, each step has a detailed prompts the operator to use intuitive and convenient through simple non-dedicated personnel trained to operate a computer. Front end software interface 1. interface image showing three images show the upper left corner of the image when the lock entrance, which vehicles to sense pressure was fixed after the first image, to be stored in the database after the automatic identification. And keep the vehicle into the driveway to the next update 2. emerged in the upper right corner to automatically recognize when the image field, while in the lower right corner to bring up the same license plate number of admission
goes to the next visual imagecontrast.
(d) Back-end senior rights management software interface is four tools image a present:
1. close button key 2. system Settings management standard tool parts 3. query tool parts 4. ID card issued a tool The Department can only issue with high-level authorization identity different rights or the operator's password to enter through the main parameter for the system to issue vehicle license plate number, or add or delete information and a variety of report generation query , the output print.
(e) Flow chart:
Vehicle arrived at the entrance,camera automatic recognized the car plate number→vehicle pass the vehicle detecter→system control the barrier open and save the vehicle enter information to check→barrier close after car pass→vehicle enter the parking lot→park car→vehicle arrive at the exit,camera automatic recognized the car plate number→vehicle pass the vehicle detecter→system automatically distinguish the property of car,barrier will automatically open when it is monthly car,hourly car check the enter information contrast and calculate the parking fee→the security man take the parking fee→confirm and open barrier→closing the barrier after the car pass.
