Description

Technical Field

[0001] This invention relates to the field of parking management system technology, specifically a parking management system. Background Technology

[0002] Parking management systems are an indispensable part of modern urban life. They integrate advanced automatic identification technology, intelligent scheduling algorithms, and cloud data management to optimize the allocation and utilization of parking resources and enhance the parking experience for drivers. This system uses high-definition cameras or RFID (Radio Frequency Identification) technology to achieve rapid vehicle entry and exit identification and automatic billing, significantly reducing waiting time and minimizing human error.

[0003] Currently, parking management systems commonly use vehicle identification systems to manage vehicles entering and exiting. When a vehicle arrives at the exit, the vehicle identification system needs to recognize the license plate information and send a signal to control the barrier lifting device to raise the barrier. However, because vehicle identification, signal transmission, and the barrier lifting process all take time, vehicles tend to stay at the exit for extended periods, especially during peak hours, which can easily lead to congestion at the exit and affect the parking lot's traffic efficiency and user experience.

[0030] This invention provides a technical solution for a parking management system: The parking management system includes an entrance identification device, an exit identification device, a central control system, and a barrier lifting device. The entrance identification device and the exit identification device are respectively installed at the entrance and exit of the parking lot to identify vehicle information entering and leaving the parking lot. The central control system is communicatively connected to the entrance identification device, the exit identification device, and the barrier lifting device to receive vehicle information and control the action of the barrier lifting device. The barrier lifting device performs barrier raising or lowering operations according to the instructions of the central control system.

[0031] The entrance and exit recognition devices include a license plate recognition camera and a vehicle sensor. The license plate recognition camera is used to capture the license plate of a vehicle, and the vehicle sensor is used to detect the presence of a vehicle.

[0032] The central control system includes a data processing module, a storage module, and a communication module. The data processing module processes vehicle information from the entrance and exit recognition devices, the storage module stores vehicle information, and the communication module communicates with the barrier gate. The system can quickly identify vehicle information and raise the barrier, reducing user waiting time and improving user satisfaction. Through intelligent management and efficient operation, the user experience at parking lot entrances and exits is significantly improved, enhancing the overall service quality of the parking lot.

[0033] The central control system calculates the vehicle recognition and barrier lifting control time using the following algorithm formula:

[0034] T = f(V) + R + P

[0035] Where: T is the vehicle passage time; f(V) is the time required for the license plate recognition camera to recognize the license plate, V is the vehicle speed; R is the reaction time of the vehicle sensor after sensing the presence of the vehicle and issuing a signal; P is the time required for the barrier lifting device to fully lift from receiving the signal.

[0036] f(V) in the algorithm formula is calculated using the following formula:

[0037] f(V)=k1*e^(-k2*V)

[0038] Where: k1 and k2 are predetermined constants; V is the vehicle speed;

[0039] The formula for calculating vehicle recognition time f(V) = k1*e^(-k2*V) offers significant advantages and benefits. First, by considering the impact of vehicle speed V on recognition time, this formula achieves dynamic adjustment of the recognition time. As vehicle speed increases, the recognition time decreases exponentially, ensuring that vehicles passing at high speeds can be quickly recognized, thereby reducing waiting time caused by recognition delays. Second, the constants k1 and k2 in this formula can be adjusted according to actual conditions, providing high flexibility and adaptability. Through this optimized calculation method, the system can maintain efficient operation under different traffic flow conditions, further reducing vehicle dwell time at exits and significantly improving parking lot throughput and user experience. Simultaneously, fast and accurate recognition helps reduce system load, extend equipment lifespan, and lower maintenance costs, meeting the requirements of modern intelligent management.

[0040] The lifting device includes a motor, a reducer, and a pole. The motor drives the reducer, which is connected to the pole to control the raising and lowering of the pole.

[0041] The central control system also includes an optimization module that dynamically adjusts the operating parameters of the barrier lifting device based on the current traffic flow in the parking lot, in order to reduce the waiting time for vehicles at the exit.

[0042] The optimization module uses the following algorithm for optimization:

[0043] T_opT = min(T0, T1 + ΔT)

[0044] Where: T_opt is the optimized barrier lifting time; T0 is the standard barrier lifting time; T1 is the current vehicle passage time; ΔT is the time adjusted according to the parking lot traffic situation;

[0045] First, by dynamically adjusting vehicle recognition and barrier control parameters, the system can quickly respond to different traffic flow conditions, improving vehicle throughput and reducing waiting time at exits. Second, based on real-time data analysis and machine learning, the optimization algorithm can adaptively adjust barrier lifting time and response speed, ensuring smooth traffic flow even during peak hours. By reducing the frequent starting and stopping of motors, the optimization algorithm not only reduces energy consumption but also extends equipment lifespan. Furthermore, the system's dynamic optimization capabilities significantly reduce congestion at exits, improving the overall user experience. In summary, this intelligent optimization algorithm gives the parking management system significant advantages in improving traffic efficiency, reducing operating costs, enhancing user satisfaction, and achieving energy conservation and environmental protection.

[0046] The central control system also includes a fault detection module to detect and record fault information of the barrier lifting device and promptly notify maintenance personnel in the event of a malfunction. This module can promptly identify and address potential problems, preventing safety hazards caused by equipment failure. An alarm device immediately notifies management personnel upon detecting anomalies, ensuring the safe operation of the parking lot.

[0047] The fault detection module includes a monitoring sensor and an alarm device. The monitoring sensor is installed on the lifting device to monitor the working status of the lifting device, and the alarm device is used to issue an alarm when a fault is detected.

[0048] Entrance Recognition Device: The entrance recognition device mainly consists of a license plate recognition camera and vehicle sensors, installed at the entrance of the parking lot. The license plate recognition camera captures images of the license plates of vehicles entering the parking lot and transmits the image data to the central control system for recognition and recording. The vehicle sensors detect the presence of vehicles; when a vehicle passes through the entrance, the sensor triggers the license plate recognition camera to take a picture. Through this device, the system can accurately record information about vehicles entering the parking lot, providing data support for subsequent management and charging.

[0049] Exit Recognition Device: Similar to the entrance recognition device, the exit recognition device consists of a license plate recognition camera and vehicle sensors, and is installed at the parking lot exit. Its main function is to capture images of the license plates of vehicles leaving the parking lot and transmit the image data to the central control system for comparison and recording. Simultaneously, the vehicle sensors detect the presence of vehicles, triggering the license plate recognition camera to take a picture. Through this device, the system can record information about vehicles leaving the parking lot and perform corresponding barrier-raising operations to ensure vehicles can leave smoothly.

[0050] Central Control System: The central control system is the core of the entire parking management system, responsible for receiving and processing vehicle information from the entrance and exit recognition devices. This system includes a data processing module, a storage module, and a communication module. The data processing module analyzes and processes vehicle information to ensure the accuracy and real-time performance of license plate recognition. The storage module stores vehicle entry and exit records and related data for easy management and retrieval. The communication module communicates with the barrier gate device, sending commands to raise or lower the barrier. The central control system also includes an optimization module and a fault detection module, capable of dynamically adjusting the barrier gate's operating parameters based on traffic flow and promptly detecting and handling equipment malfunctions.

[0051] The barrier gate system, consisting of a motor, reducer, and barrier arm, controls the raising and lowering of the access barriers at the parking lot entrance and exit. The motor provides power, which is transmitted to the barrier arm via the reducer, enabling smooth raising and lowering. The barrier gate system receives commands from the central control system to ensure vehicles can pass quickly after being identified. The system is designed with responsiveness and stability in mind to reduce vehicle waiting time and prevent exit congestion.
