Solution of license plate recognition system in Dongwo parking lot
User demand analysis
In modern parking lot management, it involves all aspects of management, in which vehicle management is an important aspect. Especially for special parking lot, compound, government organ and community, it is required to manage all kinds of vehicles in real time, strictly monitor the time of their access, and register and identify all kinds of vehicles (including internal vehicles and external vehicles). In large-scale field area, there are many vehicles in and out, for example, each vehicle needs to be judged manually, which is time-consuming, not conducive to management and query, and the security work is relatively difficult and inefficient. In order to improve this management mode which is not suitable for modern parking lot, courtyard, government organ and community, it is necessary to realize the automation and intelligence of vehicle management as soon as possible, and manage in the form of computer network, effectively and accurately monitor and manage all the vehicles at the entrance and exit. The system is required to provide corresponding application software to realize the high efficiency and intelligence of camp management.
The system uses the automatic license plate recognition algorithm of the video stream, or the ground sense trigger, to capture and identify the vehicle. When the vehicle enters the entrance of the community, the automatic license plate recognition algorithm automatically captures the vehicle photos and identifies the license plate number, and transmits and records the license plate number, color, license plate characteristic data, admission time information, etc., so that the vehicle can enter and leave the parking lot barrier free Users provide a new service model.
The system can automatically identify the number and license plate characteristics of the vehicles entering the community, verify the legal identity of the user, automatically compare the blacklist library, automatically alarm, and monitor and manage the whole parking lot, including the entrance and exit management, internal management, collection, storage data and system working status, so that the administrator can monitor, maintain, count, query and print reports Do. Vehicle access to the community is completely under the system monitoring, which makes the access, charging, anti-theft and parking management of the community fully intelligent, automatic and convenient, safe and reliable
Dongwo intelligent parking lot management system
The high-definition license plate recognition camera is used to recognize the license plate and capture the image of the vehicle entering the parking lot, transmit the license plate information to the special controller, upload it to the computer, guide the vehicle to enter, and save the record; at the exit of the parking lot, the high-definition license plate recognition camera is used to recognize the license plate and capture the image of the vehicle leaving the parking lot, and the online state is determined by the computer, and fixed The vehicle is released automatically. The offline state is judged by the parking lot controller. The fixed vehicle is released and the record is saved. If there is voice and display screen in the system, it will drive it to broadcast and display vehicle information. The temporary vehicles are managed according to the parking time to realize the vehicle in and out monitoring and management.
1. Monthly rental car realizes real offline access, and the system is more reliable
With patented technology, the monthly car rental is not affected by offline, normal in and out, the voice display screen is humanized and friendly, and the in and out records are saved to the controller. After the computer resumed work, it was uploaded automatically, which completely overturned the current market. Last month, the car rental could only be opened, and there was no in and out record and friendly prompt. At the same time, it changed the situation of system paralysis when the soft recognition was offline.
2. In the first pure license plate recognition system, temporary vehicles can be charged offline, and the system is more advanced
No matter how many computers, single computer or server are not working, the temporary vehicle can continue to enter the site and can be charged offline. The charging is not affected by the working state of the computer and server. Even if the network breaks down suddenly, the temporary vehicle in the site can continue to be charged and can be charged normally under various emergency conditions.
3. Whether the server or the computer fails, the display and voice can work normally, and the prompt is more thoughtful
In the offline state of the system, voice and display screen work normally. All the records of vehicles entering the site are stored in the access controller. After recovery, the data is automatically uploaded to the database, which changes the current offline state of the market, the display screen and voice do not work, and the system is in a paralyzed or semi paralyzed state.
4. Mobile app recognizes the entrance and exit of the site, without worrying about camera failure and toll pressure of the sentry box, and the emergency measures are more perfect (Note: specific payment is required)
In case of camera failure, the mobile app of "hand parking" can be used to identify the vehicles entering the site. After the mobile phone leaves the site and recognizes the license plate, the fees will be calculated, and the parking fees will be broadcast. After the fees are collected, the vehicles will be released. In case of peak period of vehicle exit, the "hand parking" app can be used to charge for vehicles, relieve the charging pressure of toll collectors in the sentry box, and greatly prompt the management level of the property.
5. Video stream recognition and ground sense trigger recognition are optional and more scientific
It has been debated in the industry whether video stream recognition or ground sense trigger recognition is more advantageous. In fact, in different environments, the two recognition methods have their own advantages. This system can choose video stream or ground sense trigger according to different scene environments, which is more convenient and scientific.
6. In special environment, double cameras can be used for recognition, which is more accurate
In the complex environment of curves, multiple directions and wide single road surface, double cameras can be used for recognition, which greatly improves the recognition rate.
7. The application of fuzzy calculation can further improve the recognition rate of the system and make the system more convenient with humanized operation
Mature and stable fuzzy recognition technology of license plate, locating license plate area and character recognition
