Ticket box type card swiping management system: Ticket box type/card swiping system is widely used in parking lot charging management, and the technology is very mature. It is a conventional parking lot management system
> Commercial parking lot Faced with the problems of quick access and difficulty in charging, ordinary residential areas are also facing more and more temporary vehicles, and they also need to charge for temporary vehicles to improve utilization efficiency. As the first stop for welcoming guests, the parking lot plays a more important role as a window. At present, there are traditional ticket and card issuing systems on the market for parking lot management. In recent years, Bluetooth license plate recognition systems have suddenly emerged. This is mainly because the ticket and card issuing parking lots have the following problems:

The entry and exit efficiency is low: For fixed cars, you need to swipe your card, and for temporary cars, you need to collect tickets and cards, which is inefficient
>There are many human factors in temporary car charging, which leads to a large amount of money being lost, with a loss rate of %%
>Management is difficult, as long as the card is Tickets are damaged or lost and used alternately, and efforts must be made to fill the toll hole, but with little success. It requires a lot of investment in consumables and requires a lot of maintenance
>Inconvenient and inhumane. It is very inconvenient in rainy days or if the car is not parked in place. If it encounters a landslide, it will lead to serious safety hazards. The management is not up to standard, the user experience is poor, and the image is not good. Well, the parking lot that serves as the first stop does not play the role of a front window. The Bluetooth parking system has a high card cost, and it still needs to issue temporary cards to temporary vehicles, which cannot meet the demand for quick entry. The license plate recognition parking system was born to solve the shortcomings of traditional parking lots and has won a lot of praise from customers. Its advantage is that license plate recognition can accurately identify license plates, quickly release, enter and exit efficiently, and effectively manage tolls
>License plate recognition technology is based on image processing technology and fuzzy recognition, establishing a vehicle feature model and identifying vehicle features, such as Number plate, model color, etc. It is a dedicated computer vision system targeting specific targets. It can automatically extract license plate images from an image, automatically segment characters, and then recognize characters. It uses advanced image processing pattern recognition and artificial intelligence technology to collect By processing the acquired image information, the numbers, letters and Chinese characters of the license plate can be automatically recognized in real time and accurately, and the recognition results are directly given, making computerized monitoring and management of vehicles a reality
>No need to pick up cards and tickets. It avoids the inconvenience of being exposed to the sun and rain when spitting out tickets, the strict parking distance, and serious safety hazards caused by slipping uphill.
>B system has comprehensive functions, friendly interface, simple and easy to use.
>The amount display screen adopts an integrated design of network and voice. The sound is directly emitted from the amount display screen, and the sound effect is better while wiring.
>The entire system only needs to pull power cords and network cables from the guard box to realize networking. The entire system networking is simpler and more convenient, more stable, and has higher communication efficiency, which greatly facilitates construction and debugging.
>The entrance is unattended. You can see the entrance video on the computer at the exit booth. This can be assisted by humans. As long as the unrecognized license plate is entered, the vehicle can be released.
>Modular design, to update billing rules and other updates, you only need to copy the new rules to the corresponding folder to complete the update.
>. Entrance:
> When the vehicle arrives at the entrance, after the ground sensing coil detects the signal, it triggers the vehicle identification camera to take a picture. The camera uploads the photo, and the software automatically recognizes the license plate number and uploads the software. The software is synchronized to the display screen and the barrier is raised. , the vehicle enters and the timing starts. For vehicles whose license plates cannot be recognized, the vehicle type and color are identified, the photos are sent to the system for correction processing, and the corrected results are sent to the server for storage. Then the barrier gate automatically rises, the vehicle enters the venue, and the barrier gate automatically closes after entering the venue. The parking clock starts.
>Exit
>When the vehicle arrives at the exit, the exit vehicle detector senses the signal from the ground induction coil, triggers the camera to take a picture and uploads it to the software. The software automatically recognizes the license plate number and displays the license plate number. on the screen. The system will identify the vehicle attributes. If it is a fixed vehicle or a temporary vehicle that has not reached the toll time, it will broadcast a message wishing you a safe journey, the barrier will automatically open, and the vehicle will drive away. If a temporary vehicle is parked for longer than the charging standard, the payment amount will be automatically settled and the charge amount will be played. After payment, the gate will be opened and released. For vehicles whose license plates cannot be recognized, the security will enter the vehicle number, check it with the entry, and open the gate after proper handling.
Detailed introduction to the performance indicators of the license plate recognition system: recognition rate %, actual road test daytime speed recognition rate %, the system’s time to grasp the limit and identify a vehicle, the fastest available, the search completion time (the library capacity is strips When recording) Monitoring range: One camera can monitor one lane. The effective monitoring distance of the system is about meters. With the pan/tilt and lens, it can be extended to meters or further. Image standard size*\*\*, format:\ License plate image resolution Rate: preferably pixel color: true color (bit/bit) Vehicle speed: the speed of the detected vehicle is recommended to be less than, if it exceeds, a relatively high-performance camera support is needed Application scope: red light license plate recognition system: embedded in In the post-processing software, the license plate number is automatically read to reduce work intensity. Speed alarm license plate recognition system: When a vehicle speeds, the captured license plate will be recognized as a new blacklist and automatically distributed to the management center and each inspection site, and an on-site alarm will be issued at the same time. Overload alarm license plate recognition system: When the license plate is overloaded, the captured license plate recognition will be automatically distributed to the management center and each inspection site as a new blacklist, and an on-site alarm will be issued at the same time. Blacklist audit system: Compare the recognized license plate with the blacklist (running a red light, speeding, overloading, not paying road maintenance fees, not annual inspection, etc.), and if they match, the police will be called immediately. It has unparalleled recognition speed (less than milliseconds) and can perform real-time recognition of each frame of video image without the need for a trigger device. It is especially suitable for traffic police patrol systems. Vehicle inspection management system: Save the recognized license plate and related vehicle data together to reduce labor intensity. License plate recognition checkpoint system: The recognized license plate is compared with the blacklist (wanted vehicles involved in hit-and-run accidents), and if they match, the police will be called immediately.
