Description

Technical Field

[0001] The present invention relates to the technical field of parking lot management, and in particular to an anti-car-following parking lot management system. Background Art

[0002] Parking lots and barriers are an indispensable part of modern urban infrastructure. Parking lots are mainly used to provide parking space for vehicles. With the acceleration of urbanization, the demand for parking is increasing, and the design and management of parking lots have become particularly important. Traditional parking lots are usually divided into ground parking lots and underground parking lots, while smart parking lots combine advanced technologies such as automatic identification, guidance systems and parking space management systems to improve parking efficiency and reduce labor costs. At the same time, barriers, as entrance and exit control equipment for parking lots and places such as residential areas and commercial areas, play a role in traffic control. Barriers use electric control levers or gates to restrict the entry and exit of vehicles, ensure the safety of parking lots, and prevent unauthorized vehicles from entering. Modern barrier systems usually integrate multiple identity authentication methods such as card swiping, license plate recognition, and QR code scanning. With the intelligent management system, unattended operation can be achieved, greatly improving management efficiency and traffic speed. In addition, many parking lots are also equipped with intelligent parking guidance systems, which use sensors and monitoring equipment to monitor parking space conditions in real time, help drivers quickly find vacant parking spaces, and improve user experience. With the development of intelligent technology, the combination of parking lots and barriers will be more efficient and convenient, and will help ease urban traffic pressure.

[0003] However, despite the installation of barriers at the entrance of the parking lot, there are still some low-quality car owners who follow the car in front into the parking lot when driving their cars, and then evade the parking lot's parking fees. The current barriers do not have a better way to detect and rectify this car-following behavior.

[0004] Therefore, a parking lot management system for preventing car tailgating is proposed to solve or alleviate the above problems. Summary of the invention

[0005] The purpose of the present invention is to solve the shortcomings of the prior art and to propose an anti-car-following parking lot management system.

[0008] The front license plate acquisition module is used to photograph the front license plate of the vehicle entering the parking lot and feed it back to the data processing module. The vehicle data acquisition module is used to collect the vehicle speed and passing time of the vehicle entering the parking lot and feed it back to the data processing module. The rear license plate acquisition module is used to photograph, check and record the rear license plate of the vehicle in response to the judgment of the data processing module. The data processing module is used to receive the vehicle speed and passing time of the vehicle entering the parking lot to judge the rationality, then compare the consistency of the front license plate and the rear license plate of the vehicle and record them.

[0034] The front license plate acquisition module 1 is used to photograph the front license plate of the vehicle entering the parking lot and feed it back to the data processing module 4, wherein the front license plate acquisition module 1 includes a front camera, which is used to photograph the front license plate of the vehicle entering the parking lot and feed it back to the data processing module 4.

[0035] The vehicle data acquisition module 2 is used to collect the vehicle speed and passing time of the vehicle entering the parking lot and feed it back to the data processing module 4. The vehicle data acquisition module 2 includes a distance sensor and a radar sensor. The distance sensor and the radar sensor are both used to be set on the gate pile. The distance sensor is used to detect the passing time of the vehicle entering the parking lot and feed it back to the vehicle data acquisition module 2.

The output end of the MCU is coupled to the input end of the data processing module 4. The MCU counts the duration of the distance signal as the passing time of the vehicle entering the parking lot.

[0036] The rear license plate acquisition module 3 is used to photograph, verify and record the rear license plate of the vehicle in response to the judgment of the data processing module 4. The rear license plate acquisition module 3 includes a rear camera, which is used to photograph the rear license plate of the vehicle entering the parking lot and feed it back to the data processing module 4 for recording.

[0037] The data processing module 4 is used to receive the vehicle speed and passing time of the vehicle entering the parking lot to judge the rationality, and then compare the consistency of the front license plate and the rear license plate of the vehicle and record them. The data processing module 4 includes a processor and a microcontroller. The processor and the microcontroller are coupled. The input end of the processor is coupled to the output end of the front license plate acquisition module 1, the vehicle data acquisition module 2, and the rear license plate acquisition module 3. The output end of the microcontroller is coupled to the input end of the front license plate acquisition module 1 and the rear license plate acquisition module 3.

[0038] Preferably, the data processing module 4 is used to receive the vehicle speed and passing time of the vehicle entering the parking lot to judge the rationality and then compare the consistency of the front license plate and the rear license plate of the vehicle and record them, including the following steps:

[0039] Estimate the length of the vehicle based on the speed and passing time of the vehicle entering the parking lot;

[0040] A conventional vehicle length threshold is set, and the estimated vehicle length is compared with the conventional vehicle length threshold. If the conventional vehicle length threshold is greater than or equal to the estimated vehicle length, the judgment result is reasonable. If the conventional vehicle length threshold is less than the estimated vehicle length, the judgment result is unreasonable. The conventional vehicle length threshold is 5 meters.

[0041] If the output result is reasonable, the rear license plate acquisition module 3 does not need to work;

[0042] If the output result is unreasonable, the rear license plate acquisition module 3 works and acquires the rear license plate of the vehicle;

[0043] The front license plate and the rear license plate of the vehicle are extracted for comparison. If the front license plate of the vehicle = the rear license plate of the vehicle, it is considered that there is no following vehicle and the vehicle passes independently. If the front license plate of the vehicle ≠ the rear license plate of the vehicle, it is considered that there is following vehicle and the rear license plate of the vehicle is recorded and charged.

[0044] The anti-car-following parking lot management system of the present invention is designed to effectively detect and prevent vehicles from following other vehicles when entering a parking lot, thereby avoiding the occurrence of the phenomenon of escaping the order. The system can automatically identify and determine whether there is any car-following behavior through the coordinated work of multiple hardware devices such as barriers, distance sensors, radar sensors, etc., combined with the vehicle's driving data.

[0045] First, when a vehicle approaches the parking lot's barrier, the system will quickly identify the vehicle's license plate information through the license plate recognition device on the barrier. After recognizing the license plate, the system will enable the distance sensor to accurately detect the distance between the barrier posts on both sides of the barrier. The purpose of this detection is to determine whether there are any abnormalities in the distance between the two barrier posts, especially when the vehicle passes. If the distance between the barrier posts changes and the duration exceeds a certain threshold, the system will determine that the vehicle's passing time is long, and then determine whether there may be a following vehicle entering based on the speed of the following vehicle.

[0046] Next, the system will use radar sensors to detect the speed of passing vehicles. Radar can accurately measure the vehicle's speed. Combining the detected speed and the duration of the change in the distance between the gate piles, the system can calculate the actual length of the vehicle. If the calculated vehicle length is greater than the normal vehicle length, the system will determine that the vehicle is likely to be followed by a vehicle.

[0047] Once the system determines that there may be a car following, it will initiate further detection steps. At this time, the system will use the license plate recognition device to take another photo of the license plate at the rear of the vehicle that is about to leave. After taking the photo of the license plate at the rear of the vehicle, the system will compare the license plate information recognized twice. If the license plate numbers at the front and rear of the vehicle are the same, it means that the vehicle may have just entered the parking lot alone without any car following. The system will output a "no car following" result. If the license plates at the front and rear of the vehicle are inconsistent, it indicates that there is a car following behavior, and the system will determine it as a "car following" situation.

[0048] When a following vehicle is confirmed, the system will record the license plate information of the following vehicle and automatically process the charges. Through this process, the system effectively prevents vehicles from evading charges by using the license plate information of other vehicles when entering the parking lot, thereby preventing the occurrence of evading charges. At the same time, the system will also archive the relevant data of the following vehicle for easy management and tracking in the future.

[0049] In general, the present invention can accurately determine whether there is any vehicle-following behavior through accurate detection of the vehicle's driving status, combined with license plate recognition and billing systems, and can promptly handle and bill the following vehicles. The application of this system not only improves the level of intelligence in parking lot management, but also effectively reduces the situation of parking lot fee evasion, ensuring that parking lot fee management is more fair and just.

For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
