Description

Technical Field

[0001] This invention relates to the field of intelligent parking lots, and in particular to a real-time control system for the status of parking spaces in a parking lot. Background Technology

[0002] Intelligent parking management system is a general term for modern parking lot vehicle charging and equipment automation management. The system organically combines mechanical, electronic computer and automatic control equipment as well as smart IC card technology. Under computer management, it can realize functions such as vehicle image comparison, automatic charging, and automatic data storage.

[0003] However, existing parking lots only monitor entry and exit, and the monitoring of vehicle parking status is inadequate at other times, leading to some vehicles being parked haphazardly or improperly, such as one car occupying two parking spaces, resulting in low parking space utilization. To address these issues, a solution is proposed below. Summary of the Invention

[0012] The beneficial effects of this invention are: 1. Enable parking space reservation to ensure there are parking spaces available at your destination; 2. Parking space reservations undergo dual verification to prevent unauthorized reservations; 3. Use parking robots to adjust improperly parked vehicles so that they do not interfere with the use of adjacent parking spaces; 4. For vehicles that are parked improperly and cannot be moved, a fine will be imposed, which will include additional parking fees. 5. Blacklisted vehicles are prohibited from entering the parking lot to ensure that vehicles can be parked in an orderly manner as much as possible. Detailed Implementation

[0013] The following description is merely a preferred embodiment of the present invention, and the scope of protection is not limited to this embodiment. All technical solutions falling within the scope of the present invention should be protected by the present invention. Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions, while the terms "bottom" and "top," "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0014] A real-time control system for parking space status includes a central control unit, a parking space status monitoring module, a reserved parking space management module, and a violation handling module. The parking space status monitoring module, the reserved parking space management module, and the violation handling module are all electrically connected to the central control unit. Here, "electrical connection" refers to an electrical connection capable of network interconnection, including but not limited to direct wire connection, wireless connection, Bluetooth connection, etc.

[0015] The parking space status monitoring module includes a geomagnetic sensor and a wide-angle camera. A geomagnetic sensor is embedded in each parking space to detect the presence of metal objects in real time. Wide-angle cameras are installed throughout the parking lot, based on the terrain, to ensure that each parking space is monitored by at least two wide-angle cameras. These cameras are used to monitor whether vehicles are parked beyond the lines or in spaces other than their designated spaces.

[0016] The central control unit is a PLC controller, and this design uses an STM32F103RCT6 microcontroller. The central control unit is equipped with a display screen and is located at the parking lot entrance.

[0017] The geomagnetic sensor continuously uploads the parking space occupancy status to the PLC controller. When there is only one available parking space remaining (excluding reserved but unoccupied spaces), the PLC controller enters the prediction mode: once the entrance vehicle detector senses an entry signal, it immediately controls the entrance display screen to switch to the "parking full" status to prevent subsequent vehicles from blindly entering.

[0018] Each parking space is equipped with a smart parking lock, whose retractable column integrates a license plate recognition camera. A motor at the bottom of the column drives the lifting mechanism via a threaded rod. Autonomous parking robots are deployed throughout the facility, equipped with infrared rangefinders to detect chassis height. The penalty enforcement mechanism consists of audible and visual alarms distributed on the columns, a cloud-based fine calculation system, and license plate recognition devices at the entrance gates.

[0019] After a user reserves a parking space via a mobile app, the PLC controller controls the smart parking lock to raise its column. When the reserved vehicle arrives, the parking lock's camera recognizes the license plate information, and the app simultaneously sends an arrival confirmation signal. The PLC controller compares the license plate data with the reservation record and verifies the app signal; if both match successfully, the parking lock motor is activated. The motor drives the threaded rod to rotate, causing the threaded column to retract into the ground. If the user does not arrive within the designated time, the system automatically releases the reservation.

[0020] When a wide-angle camera detects a vehicle parked over the lines, occupying multiple parking spaces, or not parked within a designated space, the PLC controller dispatches a parking robot to the scene. The robot uses an infrared rangefinder to scan the height of the vehicle's chassis to determine if it can be moved.

[0021] When the vehicle's chassis height is ≥15cm, the robot automatically performs paid handling services, moving the vehicle to a compliant location. When the vehicle's chassis height is <15cm, such as low-chassis models like sports cars, the robot sends a disable signal to the PLC controller and marks the vehicle as a violation. The instructions from the central control unit are displayed on the screen, indicating the direction of travel for the vehicles entering the parking area.

[0022] The smart parking lock includes a liftable bollard with a license plate recognition camera at the top. The license plate recognition camera is wirelessly connected to the central control unit and is used to recognize the license plate of the reserved vehicle. A motor is located at the bottom of the liftable bollard, and a threaded rod is connected to the output shaft of the motor. A threaded groove is located at the bottom of the liftable bollard, and the threaded rod is located in the threaded groove and threadedly connected to the threaded groove. The motor is controlled to start and stop through the central control unit.

[0023] The interactive terminal is set as a mobile APP. The interactive terminal is used to reserve parking spaces and confirm arrival at the reserved parking space. When the license plate recognition camera and the interactive terminal jointly confirm the arrival of the reserved vehicle, the central control unit starts the motor to retract the liftable column into the ground.

[0024] The parking robot is used to correct improperly parked vehicles. It is equipped with an infrared rangefinder to detect the vehicle's chassis height. When the vehicle chassis height is ≥15cm, the parking robot performs the handling operation; When the vehicle chassis height is less than 15cm, the parking robot sends a disable signal to the central control unit and stops the handling operation.

[0025] For vehicles that cannot be moved due to violations, penalties will be imposed, including the following: ① Push reservation status and violation notifications to the mobile APP. The maximum allowed parking time is half an hour. The PLC controller controls the display screen in the parking lot to show the license plate and start a 30-minute countdown. ② For those who fail to leave within the allotted time, the system will automatically generate a fine based on the parking duration, with a maximum fine amount set. ③ If a vehicle leaves without paying the fine, the gate will refuse to let it pass, and the system will add its license plate to the blacklist.

[0026] A control method for a real-time control system for parking space status in a parking lot includes the following steps: S1: Full Position Prediction S11: Real-time statistics of available parking spaces, excluding reserved but unoccupied spaces; S12: When there are ≤1 available parking spaces, monitor the entrance vehicle detector signal; S13: Upon detecting a vehicle entering, the entrance display screen switches to the "Parking Full" status. S2: Dual verification for reserved parking spaces S21: After receiving the reservation instruction from the interactive terminal, raise the parking lock of the target parking space; S22: When the reserved vehicle arrives, the license plate information is verified simultaneously with the arrival confirmation signal from the user terminal; S23: Lower the ground lock after successful dual verification; S3: Correction of improperly parked vehicles S31: The parking space status monitoring module monitors improperly parked vehicles both inside and outside the parking spaces within the parking lot; S32: Start the parking robot and check if the vehicle meets the handling requirements; S33: When a vehicle meets the transport conditions, a paid transport service shall be provided, and vehicle parking shall be regulated; when a vehicle does not meet the transport conditions, the transport vehicle shall be abandoned, and the vehicle shall be subject to penalties. S4: Penalties for Violating Traffic Rules S41: Display the license plate of the illegally parked vehicle on the screen and set a half-hour countdown. If the vehicle leaves the parking lot within half an hour, no penalty will be imposed. S42: Fines will be issued for vehicles that remain on the road for more than half an hour; S43: Vehicles that leave without paying fines or by other means will be added to a blacklist; S44: Blacklisted vehicles are prohibited from entering the parking lot.
