Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a parking management system,

The present application provides a technique for a parking management system that provides an efficient parking management service in a parking lot having a plurality of parking spaces.

In the case of a parking lot installed in a building with a large floating population, such as a large-scale shopping mall, a large number of vehicles are parked for a short time, and accordingly, the turnover rate of the parking lot is high. Therefore, although the parking status of each parking space changes from time to time, it is not easy for the parking lot manager and the driver to grasp such changes and perform effective parking.

In order to solve such a problem, it is necessary to display the state of the parking space at the entrance of the parking lot, for example, the number and position of the parking space that can be parked, And a technology for enabling an administrator to integrally manage the management of the entire parking lot is being developed.

The existing parking management system and the parking guidance system can help the driver to find a parking space that can be parked more quickly and easily when the vehicle enters the vehicle, or to efficiently collect the parking fee to the driver in the position of the parking manager Was a system for.

However, one of the problems that frequently occur in parking management in practice is that a vehicle occupies a parking space unnecessarily for a long time, thereby reducing the number of available parking spaces, and in addition, the parking position of the long- It can not be used efficiently. For example, in the case of a driver who intends to use a short-term parking lot, he / she generally wants to park in a position where the driver can easily access the building after the parking. Therefore, if a long-term parking vehicle is parked in a parking space where the vehicle is often in and out of the vehicle, it may cause an atmospheric phenomenon at the entrance of the parking lot and congestion of the traffic thereby causing a deterioration in the overall efficiency of the parking lot management .

Therefore, the manager of each parking lot periodically used various methods such as memorizing and managing the long-term parking vehicle through a method of memorizing the car number of all the vehicles in the parking lot, and the like. However, these methods are time consuming, There is a problem that accuracy is also lowered. Also, there is a problem in that the parking lot in which the parking guidance system is installed is checking the long-term parking position on the screen of the main computer by the sensor installed in each parking space.

The present application aims at providing a means for solving the problems of such a conventional parking management system, specifically, that the management of a long-parked vehicle is not efficiently performed.

The present application is based on the first embodiment and discloses a parking surface sensor installed in each parking space and detecting whether or not there is a vehicle parked in the parking space. The parking surface sensor calculates the parking time of the parked vehicle in the parking space, compares the parking time with the predetermined time, and determines that the vehicle is a long-term parked vehicle if the time exceeds the predetermined time. If it is determined that the vehicle is a long-term parked vehicle, the light emitting unit performs an operation indicating that the vehicle in the parking space is an long-term parked vehicle.

The present application, as a second embodiment, discloses a parking system for managing a long-term parked vehicle. The parking management system includes a parking surface sensor, a parking space indicator, an upper control unit, and a central management computer. The parking sensor detects whether the vehicle is parked in the parking space and transmits the signal to the central management computer via the upper control unit. The central management computer checks the parking time of each parking space through a signal from each parking surface sensor, and determines that the vehicle is a long-term parked vehicle when the parking time exceeds a predetermined parking time. The control unit transmits a signal to the upper control unit with respect to the parking space corresponding to the vehicle determined to be the long-term parking vehicle, and the upper control unit controls the parking space sensor or the parking space display lamp of the parking space to perform an operation of indicating that the vehicle is the long- .

The present application is a third embodiment, which discloses a parking management system for managing a long-term parking vehicle using a camera. The cameras may be installed in each parking zone, in each parking space, or at the entrance and / or exit of the parking lot. The camera may collect image information of the vehicle when the vehicle enters the parking lot, departs, parks, or runs in the parking lot. In particular, if it is determined that the car is a long-term parked vehicle, the camera may collect the car number information of the car in the parking space and transmit it to the central management computer through the host control unit. Thus, the central management computer can more effectively manage the car number information of long-term parking vehicles.

As such, the techniques disclosed in this application can provide a more efficient and automated system for recording and managing information of long-parked vehicles.

Hereinafter, specific embodiments of the present invention will be described with reference to the drawings.

The embodiments of the present invention disclosed in the present application are illustratively disclosed to explain the technical idea of the present invention, and the technical idea of the present invention is not limited to the embodiments. Those skilled in the art will appreciate that various modifications, substitutions, and adjustments may be made without departing from the spirit and scope of the present invention.

1 is a view schematically showing a first embodiment of the long-term parking management apparatus disclosed by the present application. More specifically, FIG. 1 shows an example of a long-term parking management apparatus installed in one parking space disposed inside a parking lot.

As shown in FIG. 1, each parking space is provided with a parking surface sensor for detecting whether or not the vehicle is parked. The parking surface sensor is a sensor for judging whether or not the vehicle is parked in the parking space, and it is installed at a proper position to check whether or not the vehicle is parked. For example, a parking surface sensor may be installed above a parking space surface where a vehicle is parked to sense an object entering or exiting or occupying the parking space, thereby detecting whether the vehicle is parked. For example, an ultrasonic sensor, a camera, an infrared sensor, a loop sensor, a geomagnetism sensor, or the like can be used as the parking surface sensor, but it is not limited to a specific sensor as long as it can determine whether an object exists in the sensing area, Do not.

The parking surface sensor includes a control unit and a sensor unit, and may further include at least one of a light emitting unit, an audio output unit, a character display unit, a communication unit, and a memory unit. The sensor unit detects whether or not the vehicle is parked in the parking space, calculates the parking time at the self-control unit, and judges whether or not the vehicle corresponds to the long-term parked vehicle exceeding the predetermined time. And visually indicates that the vehicle in the parking space is a long-term parked vehicle. For example, the light emitting unit may indicate whether the vehicle in the parking space is a long-term parked vehicle by indicating whether the vehicle is lit or lighting the light through the lighting color, or by flashing the light emission at a predetermined cycle.

Also, the audio output unit may indicate that the vehicle is a long-term parked vehicle through the audio output with the light emitting unit or separately from the light emitting unit. For example, it may output sounds that warn the attention, or it may indicate that the vehicle is a long-term parked vehicle through a voice signal.

The character display unit may also display a visual character so that the vehicle driver or the parking operator of the parking space can recognize that the parking vehicle is a long-term parking vehicle.

The communication unit enables communication between the parking surface sensor and the host control unit or the central management computer. A parking surface sensor installed in each of the one or more parking spaces may be controlled through an upper control unit, which may be supervised and managed by a central management computer. Specifically, the high-level control unit receives signals from the respective parking surface sensors, transmits the signals to the central management computer, and receives signals from the central management computer to control the parking surface sensors based on the signals. The communication between the parking surface sensor, the upper control unit, and the central management computer may be various communication methods known to those skilled in the art as communication via wired or wireless communication. Of course, the parking surface sensor may operate independently without a communication unit, a higher-level control unit, and a central management computer to select and display long-term parking vehicles. For example, if the sensor unit of the parking surface sensor detects that the vehicle is parked in the parking space and transmits it to the self-control unit, the self-control unit calculates the parking time and if it exceeds the predetermined time, can do. When it is determined that the vehicle is a long-term parked vehicle, the self-controller may control the operation to indicate that the vehicle in the parking space is a long-term parked vehicle through at least one of the light emitting portion, the character display portion, and the audio output portion of the parking surface sensor.

The central management computer can receive and monitor the parking situation of the entire parking lot by receiving signals from the respective parking surface sensors or the upper level control unit and transmit signals to the respective parking surface sensors to control the operation thereof . For example, the central management computer displays the parking time of each parking space, and the user may set the reference parking time to be judged as the long-term parking vehicle according to the actual situation. According to the set reference parking time, each parking surface sensor may determine whether the vehicle in the parking space is a long-term parked vehicle, and accordingly, indicate that the vehicle is a long-term parked vehicle through the light emitting portion, the character display portion, or the audio output portion.

On the other hand, each parking space may be provided with a parking space indicator separately from the parking sensor. The parking space indicator is a device that makes it easier to identify whether the vehicle is parked in the parking space.

Specifically, when the parking surface sensor or the upper control unit transmits a signal to the parking space indicator indicating whether the vehicle is parked in the parking space, the parking space indicator visually indicates whether or not the parking space is currently occupied. Accordingly, the driver entering the parking lot can visually and immediately confirm the specific position of the empty parking space present in the parking lot through the signal of the parking space indicator.

For example, when the signal inputted from the parking surface sensor indicates that the corresponding parking space is occupied, the parking space indicator lamp is turned off, and when the parking space is available, the parking space indicator lamp is turned on, There is no need to roam the parking lot to find an empty parking space that can be accessed towards the space light. Alternatively, the color of the parking space indicator may be used to illuminate the indicator in green when parking is available and red in a parking indication, so that the driver can immediately grasp the space available for parking through color classification. Also, the parking space indicator lamp may function as the light emitting portion of the parking surface sensor when the vehicle on the parking surface is a long-term parking vehicle. Further, the parking space indicator lamp may be installed for a parking area including a certain number of parking spaces.

The parking space indicator lamp may further include an audio output unit, a communication unit, a memory unit, and the like in addition to the light emitting unit. The communication unit may enable communication between the parking space indicator and the upper control unit or the central management computer, as well as signal communication between the parking space indicator and the parking sensor. That is, the lighting state of the parking space indicator may be managed or supervised by the upper control unit and the central management computer for managing the same, and thus, immediate confirmation and measures can be taken when there is an abnormality in the parking space indicator, for example .

In addition, the audio output unit may transmit various information related to parking to the driver who parks in the parking space through a voice signal.

Specifically, when it is determined that parking is completed in the parking space, information related to parking may be provided from the audio output unit after a predetermined time after the driver leaves the vehicle. For example, various information such as a zone number indicating the position of the parking space, a charge information of the parking lot, various information about the building (event information, business hours information, etc.) may be provided. It may also output sound or voice signals indicating that the vehicle is a long-term parked vehicle.

FIG. 2 is a schematic view of a parking system for integrally controlling and managing a parking surface sensor and a parking space indicator installed in each parking space.

As shown in FIG. 2, the parking surface sensor and the parking space indicator installed in each parking space are controlled by the upper control unit, the upper control unit communicates with the central management computer, and the parking lot manager communicates each parking space through the central management computer Can be managed.

Specifically, the parking surface sensor of each parking space transmits the occupancy state of the parking space to the upper control section, and the upper control section transmits the occupancy state to the central management computer. Further, the upper control section may control the operation of the parking space indicator lamp according to a signal from each parking surface sensor. For example, upon receiving a signal from the parking surface sensor to determine that the parking space is occupied, the parking space indicator for the parking space may be operated in a light emitting mode indicating the parking status. When receiving a signal for confirming that a predetermined time has elapsed after the completion of the parking operation to the extent that the driver comes out of the vehicle, voice information about the parking space may be provided through the audio output unit of the corresponding area.

Also, the central management computer may judge the vehicles parked for a predetermined time or more based on the received information as long-term parking vehicles, and check how many long-term parking vehicles are parked in a specific area in the parking lot or the vehicle number of the vehicle have. The specific value of the predetermined time for judging the long-term lane difference vehicle can be set so that the user is in a real situation. Therefore, when the parking time of the parking space transmitted from the parking surface sensor exceeds the predetermined time, the central management computer transmits a signal indicating that it is determined to be the long-term parking vehicle to the parking surface sensor for the parking space, It is possible to perform an operation of notifying that the vehicle is a long-term parked vehicle. Alternatively, the control unit may output a signal indicating that the vehicle is a long-term parked vehicle when the predetermined time is transmitted to the high-level control unit or each parking surface sensor and the parking time in each parking space exceeds a set time.

The central management computer may display a long-term parking vehicle for a parking vehicle that has passed a predetermined time set through the display means, and display the parking position, the parking time, and the vehicle number of the vehicle. The confirmation of the vehicle number can be confirmed by a video signal through a camera or the like installed in the parking space, or the manager can check the position of the long-term parking vehicle by at least one of the light emitting unit, the audio output unit and the character display unit, The vehicle number of the vehicle may be transmitted to the central management computer via the portable terminal device. That is, the central management computer is set so as to be able to communicate with the portable terminal device, and the administrator can set the vehicle number of the long-term parked vehicle checked through one or more of the light emitting portion, the audio output portion, Or may be input to the central management computer through the portable terminal device.

Accordingly, in the central management computer, data such as the position and the vehicle number of the long-term parked vehicle in the entire parking lot can be comprehensively managed and the statistics can be created, and the parking lot manager can perform the image processing So that it can be easily recognized.

In this manner, since the parking status in the parking lot is integratedly managed through the central management computer, the manager can more easily identify and manage the long-term parking vehicle.

In FIGS. 1 and 2, the parking surface sensor and the parking space indicator are shown as being independent of each other, but this is merely one exemplary embodiment, and the present invention is not limited to this.

For example, the parking sensor and the parking space indicator may be in one configuration. The operation in this case will be described in detail as follows.

First, when the vehicle is not parked in the parking space, the parking surface sensor indicates that the parking space is a space available for parking through the light emitting portion. For example, it may be lit in green. When the vehicle then displays the display and enters the parking space to complete parking, the parking surface sensor senses the parking space and displays through the light emitting unit that the parking space is the occupied space. For example, it may be turned on or off in red.

Further, position information, parking fee information, and the like of the parking space may be provided from the audio output unit in accordance with the timing when the parking surface sensor judges that the parking is completed and after a predetermined time, specifically when the driver comes out of the vehicle.

Then, when the vehicle in the parking space is out of the parking space, the parking surface sensor senses it and transmits a signal to the light emitting unit, and the light emitting unit indicates that the corresponding parking space is available for parking.

On the other hand, when it is determined that the vehicle is parked in the parking space for a predetermined time or more, the parking surface sensor judges that the vehicle is a long-term parking vehicle. The determination of the parking time may be determined through a central management computer in communication with the parking sensor, or may be determined through the parking sensor's own process. That is, the parking surface sensor stores the parking start time in the memory through its own process, and may determine that the vehicle is a long-term parked vehicle when the parking duration time exceeds a predetermined time.

When the vehicle in the parking space is judged to be a long-term parked vehicle, the light emitting portion of the parking surface sensor can visually display it. In this case, it may indicate that the vehicle is a long-term parked vehicle through a color different from the display indicating the parkable state and the occupancy state of the parking space, or a different type of light emitting mode. For example, the light emitting unit is turned on with green, non-red, or the like, or the light emitting unit is blinked at a specific cycle so that the driver or the parking lot manager can visually distinguish easily. Also, it is possible to indicate that the vehicle is a long-term parked vehicle through the audio output unit or the character display unit.

Also, the management of the long-term parked vehicle may be performed individually through the parking surface sensor of each parking space without through the central management computer.

For example, the parking sensor installed in each parking space compares the parking time of the parked vehicle with the parking time determined as the long-term parked vehicle through the own process, thereby checking whether the vehicle is a long-term parked vehicle If it is determined that the vehicle is a long-term parked vehicle, it may indicate that the vehicle is a long-term parked vehicle through the light emitting unit, the character display unit, and / or the audio output unit.

Therefore, the parking lot manager can check whether or not the vehicle parked in the parking space is the long-term parking vehicle through the light emitting portion of the parking surface sensor of the individual area, the output contents of the character display portion or the audio output contents, The vehicle can be managed.

3 and 4 are views schematically showing an embodiment of a parking system to which a camera system is applied.

At the entrance of the parking lot, one camera is installed in front / rear / left / right so that the exterior of the vehicle can be photographed. Alternatively, one camera may be installed on the front side and the rear side. The camera is installed to be able to confirm the appearance state of the vehicle entering the parking lot, and the number and position of the installed cameras are not particularly limited. In addition, a camera capable of photographing the exterior of the vehicle is also provided at the exit of the parking lot.

The parking lot is divided into a plurality of zones such as the first zone, the second zone, the third zone and the fourth zone.

In Fig. 3, a camera is installed in each zone to collect the appearance state and / or the vehicle number of the vehicle. The camera installed in each zone may be installed either at the entrance and exit of the zone or at either the entrance or the exit, depending on the structure of the parking lot, considering the organic connection with the adjoining zone, Can be determined.

In FIG. 4, the camera installed in each area may receive the position information of the specific parking space, which is determined to be the long-term parking space, from the parking sensor or the upper control unit, and collect the vehicle number of the parked vehicle in the parking space. At this time, a fixed camera in charge of a plurality of parking spaces may take a picture or a moving camera in charge of a certain section may move to the parking space or take a picture by rotating the direction.

5 is a block diagram schematically illustrating the processing steps of the information collected from the camera.

Information of the vehicle photographed until the vehicle enters / parks the vehicle from the camera 21 disposed in each of the parking lot entrance / exit and parking areas, or vehicle information photographed as the long-term parking vehicle, Lt; / RTI > The upper control unit 22 controls the camera 21 of the parking lot entrance / exit and / or each area, receives data about the vehicle from the camera, and transmits the data to the central management computer 23. Further, the upper controller 22 may analyze and correct the received data before transmitting the data to the central management computer 23. For example, the upper control unit may identify the vehicle number through the vehicle data transmitted from the camera, process information of the vehicle based on the number, and correct the captured image if it is unclear. Alternatively, the higher-level control unit may collectively transmit the data transmitted from the camera to the central management computer, and may perform the above-described processing on the central management computer. In consideration of technical matters such as the number and number of cameras, the upper controller may be provided with one upper controller in one camera or one upper controller in a plurality of cameras, so that a plurality of upper controllers may exist in the entire system .

For identification of the vehicle number, for example, an LPR (License Plate Recognition) system may be used.

The central management computer 23 collectively manages and processes the transmitted vehicle data. Specifically, the central management computer 23 can manage the information of the vehicle entering the parking lot according to the vehicle number of the corresponding vehicle. For example, the central management computer can manage data such as the appearance state at the time of entry of the vehicle, the movement line in the parking lot, the parking position, and the appearance state at the time of leaving the parking lot according to the vehicle number.

A terminal 24, for example, a kiosk, is installed at an appropriate location where the driver can easily access, such as at each floor of the car park, or near an elevator. The kiosk can be connected to the central management computer and display the data of the vehicle stored in the central management computer. For example, if the driver can not remember where he parked his vehicle, the driver enters his car number in the kiosk. In this case, the kiosk can display the information of the vehicle corresponding to the vehicle number, for example, the position where the vehicle is parked, the appearance state upon entry of the vehicle, and the like. If there are a plurality of vehicles having the same car number, a photograph taken by the camera and time information may be attached so that the car can be identified.

In addition, when the driver's vehicle is stolen / damaged, the driver can check the stolen / damaged position or the like of the vehicle by reading information on the situation after the vehicle enters the parking lot through the kiosk, .

More preferably, the image of the vehicle photographed by the camera at the entrance of the parking lot may be compared with the image of the vehicle photographed at the exit of the parking lot, so that it is possible to check whether or not there is a change in the exterior appearance of the vehicle in the parking lot. For this purpose, it is possible to apply software that compares the image data at the time of entering the parking lot with the image data at the time of leaving the parking lot, and checks and displays the changed portions. Through this, the user can check the change of the vehicle state before and after entering the parking lot through the kiosk at a glance.

In addition, when the user leaves the parking lot without using the terminal, the user can be informed of the change in the appearance of the vehicle. That is, the camera for checking the state of the vehicle leaving the parking lot compares and analyzes the image at the time of shooting and the image of the vehicle state at the time of entering the parking lot of the vehicle, and if the images are different when the vehicle enters and exits the parking lot, You can tell the driver. For example, a notice board or an audio output unit installed at the exit of the parking lot may indicate that the vehicle has changed to a state of the vehicle, and may specifically notify which part has changed. Therefore, the driver can confirm the breakage or change of the vehicle which he had not recognized before leaving the parking lot.

Such information may be provided through various terminals other than the kiosk, or may be provided through a personal terminal. For example, a driver can access a system through his / her own mobile phone, PC, PMP, or the like, and can search through his / her car number to check various information.

Further, in the case of paying the parking fee at the unmanned fare adjuster in the parking lot, information on the location of the vehicle may be printed on the ticket of the customer, information indicating the route from the current position to the position of the vehicle may be printed on the ticket of the customer, Alternatively, information may be provided visually through the display of the unattended fare adjuster. Further, the unmanned fare adjuster and the kiosk may be combined to perform confirmation of vehicle information and payment of a parking fee through a single device.

Furthermore, even in the case of collecting the parking fee, the vehicle number of the vehicle is recognized through the camera at the time of entering the parking lot, so that it is not necessary to issue a separate parking ticket. That is, since the time of entering the parking lot of the vehicle can be confirmed through the camera, it is possible to check the time of entering and leaving the parking lot without having to issue a separate parking ticket, so that the accurate parking charge can be collected.

In addition, the collected vehicle information may be utilized for various purposes. That is, in addition to checking the parking position of the vehicle and performing security functions in the parking lot, various services can be provided using the information of the collected vehicles.

For example, it is possible to recognize a vehicle number of a vehicle entering a parking lot through a camera, collect data based on the vehicle number, analyze and statistically analyze the data, and provide various services. Specifically, it is possible to know the information about the area of the parking lot of the corresponding parking lot through the local information of the recognized license plate, for example, the area of the major customers such as shopping center, department store, hospital, It can be possible. Also, the driver's address can be grasped through the vehicle number to deliver the promotional mail, and the customer using the business can be more aggressively managed.

In addition, when a specific vehicle stored in the central management computer enters a parking lot or enters a specific area within the parking lot, it is possible to provide a warning or voice warning sound or sound for guiding or regulating / controlling the vehicle to the destination May be provided, or the above information may be provided through an induction sign that visually indicates the information and the direction. In addition, it is possible to smoothly improve the parking lot around the copper wire, which is mainly used, by grasping the movement line of the vehicle moving within the parking lot.

Further, as another embodiment of the present application, a parking management system using a camera may be used in a system for managing a long-term parked vehicle.

In a specific operation of the embodiment, a parking surface sensor installed in each parking space determines whether the vehicle is parked in the parking space, whether the parked vehicle is a long-term parked vehicle, and transmits it to the upper control unit. Signals from the respective parking surface sensors transmitted to the upper control unit may be transmitted to the central management computer so that the entire status of the parking lot may be managed through the central management computer.

On the other hand, when the parking surface sensor judges that the vehicle in the parking space is the long-term parking vehicle, it transmits a signal to the high-level control unit, and the high-level control unit controls the camera so that the vehicle of the long- Check the number information. The upper control unit can manage the location and the vehicle number information of the long-term parked vehicle through the central management computer by transmitting the vehicle number of the long-term parked vehicle to the central management computer.

In addition, the central management computer may transmit the location and the vehicle number of the long-term parked vehicle to the manager through the portable terminal so that the manager can more easily respond to the long-term parked vehicle.

The ability to distinguish such long-term parking vehicles can reduce the number of long-term parking vehicles and allow long-term parking vehicles to be parked in separate areas, thereby helping general parking customers. It is possible to reduce the number of cases in which the vehicle is parked in the passageway, thereby preventing an accident in the parking lot. In addition, it is possible to prevent the traffic congestion from occurring by decreasing the waiting vehicle at the entrance.
