Description

Technical Field

[0001] The present invention relates to the technical field of parking lot management, and specifically to a method for quickly calibrating the remaining spaces in a parking lot. Background Art

[0002] In the existing parking lot management industry in our country, many currently adopt unattended operation, with no one at the entrance and exit, and abnormal situations are solved using a call device. After the departure of personnel on duty, there is a common situation where the information on the number of available parking spaces in an unattended parking lot is inaccurate, resulting in the malfunction of the parking guidance function.

[0003] The specific reasons are mainly as follows:

[0004] 1. The vehicle fails to fully enter the parking lot but is recorded as having entered. This situation generally occurs at the entrance of the parking lot. A passing vehicle makes a U-turn or abandons entering, but the entrance license plate recognition camera has already captured the license plate or the inductive loop has been triggered. Since the vast majority of unattended parking lots have no traffic restrictions on entering vehicles, when the license plate recognition result is received, the gate bar is opened for the vehicle to enter. As a result, the parking management system subtracts the number of available berths. Unless manually intervened remotely, the system automatically records a vehicle as having entered.

[0005] 2. Vehicles enter the parking lot following one another. Due to the limited number or angle of camera deployments, the parking management system fails to detect this, and the number of remaining spaces that should be subtracted is not subtracted. This can also result in a situation where the parking guidance shows that there are available spaces in the parking lot, but in fact, all the spaces are occupied.

[0006] 3. Vehicles leave the parking lot following one another. Due to the limited number or angle of camera deployments, the parking management system fails to detect this, and the number of remaining spaces that should be increased is not increased. This can also result in a situation where the parking guidance shows that there are no available spaces in the parking lot, but in fact, there are empty spaces.

[0007] 4. After a power outage or network disconnection, the gate is automatically opened for vehicle passage. Since the license plate recognition device or other vehicle inspection devices are out of power and cannot work, the data on entering and leaving vehicles cannot be collected and transmitted to the parking management system. As a result, there is no record of vehicles leaving the parking lot during this period in the parking management system. This can also lead to a situation where the vehicle has left, but the number of remaining spaces has not increased.

[0008] 5. The vehicle returns to the parking lot. That is, when the vehicle is in the exit lane and obtains permission to leave, the gate bar rises, and the system records it as having left the parking lot, but the vehicle reverses back into the parking lot and abandons leaving. Such an operation, without manual correction, will also cause the number of remaining spaces in the parking lot to increase when it actually has not.

[0009] Currently, in the parking operation industry, to solve the inaccuracy of the number of remaining spaces in the parking lot under the unattended state on-site, the following methods are generally adopted:

[0010] 1. Install parking space sensing devices. Install active or passive vehicle detectors, such as geomagnetic sensors and ultrasonic sensors, in each parking space. Use the sensors to obtain accurate information on whether there is a vehicle in the parking space, so as to obtain the accurate number of remaining parking spaces.

[0011] 2. Add auxiliary identification. By widely installing license plate recognition devices, strive to filter out invalid occupancy information formed in situations such as vehicles returning to the field, following closely, and passing by.

[0012] 3. Increase manual remote control. Lift the barrier after vehicle entry is confirmed, and conduct video recording when the vehicle exits. Manually supplement the vehicle flow records of vehicles following closely and returning to the field to ensure the accuracy of the remaining spaces in the field.

[0013] 4. By installing vehicle detector induction coils in the import and export channels and cooperating with counters, subtract the number of incoming vehicle inductions from the number of outgoing vehicle inductions to obtain the number of remaining spaces in the field.

[0014] All of the above methods have the situations of high equipment and manpower investment and still poor effects. In case of power failure or network disconnection, the additional equipment and remote labor are useless. The industry urgently needs a technical system that can solve the accuracy of the remaining space data in the field and can also achieve low-cost operation. Summary of the Invention

[0015] The purpose of the present invention is to provide a method for quickly calibrating the remaining spaces in a parking lot to solve the problems raised in the above background technology.

[0017] Among them, in the above Step 1, it specifically includes the following steps:

[0018] 1) Establish a remaining space calibration system and register the parking lot information that needs to be calibrated for remaining spaces on the system;

[0019] 2) Each parking lot establishes a database on the remaining space calibration system, which includes three lists.

[0035] 3) The remaining space calibration system imports List 1 into the database by means of export or data synchronization;

[0036] Among them, in the above step six, it specifically includes the following steps:

[0037] 1) The remaining space calibration system screens out the license plate numbers that are not in List 1 but exist in List 2, and queries through the parking management system whether the vehicle has left the lot during the inspection; if it has left, it is not counted as a vehicle present. If there is no entry record for such a vehicle, the parking system is notified to handle the supplementary entry record.

[0038] 2) Finally, the remaining space calibration system calculates the number of license plates in List 2 minus the number of license plates that have left the lot during the inspection, and the resulting value is the current most accurate remaining space quantity.

Before the formal inspection starts, testing must be carried out. The inspection route is tested, and the field can be patrolled in the shortest time. The postures of the movable camera and the handheld terminal device are adjusted to the angles that can obtain the license plate recognition results fastest and most stably. The optimal values obtained from the test are recorded in the configuration of the parking lot. When the remaining space calibration operation is performed on this parking lot again, the inspection system automatically retrieves the historical configuration of this parking lot without the need for testing;

[0062] 2) The postures of the movable camera and the handheld terminal device are adjusted to the angles that can obtain the license plate recognition results fastest and most stably;

[0063] 3) The optimal values obtained from the test are recorded in the configuration of the parking lot;

[0064] Among them, in the above step 4, it specifically includes the following steps:

[0065] 1) The mobile inspection system patrols according to the specified route and equipment posture. When passing by the outside of the berth, the camera viewfinder program captures the license plate features, triggers taking pictures and conducts license plate recognition.

[0072] Among them, in the above step 6, it specifically includes the following steps:

[0073] 1) The remaining space calibration system screens out the license plate numbers that are not in List 1 but exist in List 2, and queries through the parking management system whether the vehicle has left the field during the inspection period. If it has left the field, it is not counted as an on-site vehicle. If there is no record of such a vehicle entering the field, the parking system is notified to handle the supplementary registration of the entry record.

[0074] 2) Finally, the remaining space calibration system calculates the number of license plates in List 2 minus the number of license plates that have left the field during the inspection, and the obtained value is the current most accurate remaining space number.
