Description

Parking management system and method {PARKING MANAGEMENT SYSTEM AND METHOD}

The present invention relates to a parking management system and method, and more particularly to a parking management system and method that can guide and manage a vehicle entering a parking facility to a designated place by designating a parking lot.

In general parking management, the parking agent distributes the parking ticket with the entry time at the entrance of the parking lot and pays the parking fee when leaving the parking lot. However, when such parking management is applied to a large parking lot such as a department store or a discount mart, many parking personnel must be arranged as well as various irregularities may be involved, which may lead to a casualty such as non-paying of parking fees. Korean Patent Laid-Open Publication No. 2000-0031655 and 2000-0067195 disclose a parking management system and a method for solving such a problem, respectively.

As shown in FIG. 1, Korean Patent Publication No. 31655 collects a vehicle detection signal from a roof coil vehicle detection sensor unit 500 and stores parking information indicating a parking time and parking availability for each parking booth in a memory. 510 and the parking information is provided by wire or wireless. In addition, the wireless handheld terminal and the fare checker are a system that performs toll collection based on the parking information provided by wired and wireless, checks the tolerance status, and calculates the parking fee automatically.

However, such a parking management system and method should bury the loop coil (vehicle detection sensor) at a certain depth below the ground level of the parking lot, and the sensitivity of the sensor is such that the size of the loop leads, the short-circuit resistance to the ground and the resurfacing on the roadway Over-Lay) layer is affected by the thickness. The current flowing through the roof coil can be relatively strong in the vehicle, and the magnetic field of the coil is likely to cause a fatal effect on the electronic control device when starting the vehicle, causing a safety accident such as a sudden start. In addition, since the coil buried under the ground may break due to frequent movement of the vehicle, and eventually cause a malfunction. If the information is used to guide the vehicle to the parking area, it causes a lot of confusion. Therefore, in such a parking management system and method, the roof coil has to be used as an auxiliary means and there is a problem that other main sensing systems that can be always detected are required. On the other hand, such a parking management system and method has a problem that the information about the vehicle is not grasped at all, so it is necessary to carry and monitor the wireless portable terminal. Therefore, when the parking space is large, it is necessary to secure parking personnel in various places. There is a problem to rely on the parking personnel to induce.

As shown in FIG. 2, the Patent Publication 67195 discloses a photoelectric sensor installed at a vehicle and whether the vehicle is parked in or out of a vehicle to recognize a vehicle being parked in each parking area and to drive a relay. The microprocessor of the central control unit receiving the information selectively turns on the LED so that the administrator can recognize it. In addition, the segment driving IC of the parking guide unit informs the 7-segment of the vehicle that is being parked for the parking number and the number corresponding to the floor and the location of the parking area, and the entry time and the parking position of the vehicle in the machine under the control of the central control unit. A parking ticket will be issued to inform you in text.

However, such a parking management system and method requires the installation of a photoelectric sensor at the entrance and the respective parking area (parking booth), so that the initial installation cost is very high and the continuous maintenance cost is paid. It acts as an obstacle to the vehicle, causing accidental accidents. In addition, temporarily placing objects in the parking booth near the photoelectric sensor is also recognized as the parking of the vehicle is delivered to the central control unit to cause the administrator to confirm. If the light emitting diodes that inform the driver of the parking position are located in the parking area or a certain area, respectively, if several parking vehicles to be parked move to the corresponding area at the same time, the lights are turned on at the same time or by a certain time difference. There is a risk of weighting.

However, according to the conventional technology 2, the vehicle must be stopped once to enter the parking lot, and the 7-segment in front of the vehicle is not only causing the traffic jam when entering the parking lot, but also causing the driver's dissatisfaction. In addition, it is not efficient to operate a large parking lot when the vehicle driver is shown to the vehicle driver as a 7-segment when the driver attempts to enter the parking lot and the driver needs to see the parking ticket and check the parking position again.

The present invention provides a new type of parking management system and method for easily operating the system while maximizing the efficiency of the parking space. In particular, the present invention is to provide a new type of parking management system and method that can reduce the parking personnel and transparently manage the parking facilities while maximizing the satisfaction of the driver.

Thus, in the parking management system according to claim 1 of the present invention, the reader unit is installed at an entrance of the parking facility and an entrance reader for detecting entry of the vehicle; A main passage reader installed at a main passage of the parking facility for detecting entry of the vehicle into the parking area; A passage reader installed in a passage of the parking area to detect entry of the vehicle into the parking cell in the parking area; Is installed above the parking cell may include a cell reader for detecting the parking of the vehicle in the parking booth in the parking cell.

Thus, in the parking management system according to claim 1 of the present invention, the display unit is installed at the entrance of the parking facility and the parking area guidance display for guiding the parking area of the vehicle according to the transmission signal of the central control unit; A parking cell guide display installed at the main passage to guide the parking cell of the vehicle; Installed at the entrance of the parking cell may include a parking booth induction display for guiding the parking booth of the vehicle.

Thus, in the parking management system according to claim 1 of the present invention, the cell reader may include a reader configured to integrally combine two motors with a joint and rotate at a constant rotation speed and rotation angle about a Z axis and an X axis. .

As described above, the parking management system according to any one of claims 1 to 4 of the present invention further includes a parking position guide display installed at a predetermined position in the parking facility or in a facility having the parking facility and connected to the central control unit. However, the parking position guide display window and showing a vehicle number; A window showing a parking booth code; A window showing a parking position; A window showing parking information such as a parking time and a parking time; The parking lot may be provided with a keypad for operation.

Thus, in the parking management system according to any one of claims 1 to 4 of the present invention, the parking sensor may be a built-in piezoelectric sensor installed in a wheel stopper for limiting the position of the wheel of the vehicle in the parking booth.

According to another aspect of the present invention for achieving the above object, the parking management method using the parking management system is a step of recording the entrance time when the vehicle entering the entrance of the parking facility is detected and confirming the approval of the vehicle Wow; Designating a parking area, a parking cell, and a parking booth of the vehicle by identifying a parking state in a parking facility when the approval of the vehicle is confirmed; Guiding a designated parking area of the vehicle when the vehicle enters a parking facility; Detecting the vehicle moving along the main passage and guiding the designated parking cell when the vehicle reaches the entrance of the designated parking area; Detecting the vehicle moving along a passage of the parking area and guiding the designated parking booth when the vehicle reaches the entrance of the designated parking cell; And confirming that the vehicle is parked in the designated parking booth.

As described above, each step of guiding a designated position of the vehicle in the parking management method according to claim 7 may be automatically guided after a predetermined time passes after the previous step is completed or after detecting a tag of each step. Can be.

Thus, in the parking management method according to claim 7 of the present invention, the distance measurement of how far the RFID tag installed in the vehicle using the parking facility is from the reader detecting the entry state of the vehicle is based on the signal value reflected from the tag. Each threshold can give a distance rating.

The present invention has been invented to overcome the limitations of the existing parking management system and method. Due to the development of semiconductor chip manufacturing technology, a chip capable of driving a low power of a CPU is commercially available. It can be easily and easily attached to the tag without obstructing the driver's vision because the tag can be manufactured lightly and simply as the size of a credit card without the built-in.

According to the parking management system and method of the present invention, since it can be used immediately as a toll collection system and uses a high-frequency carrier signal, it is not necessary to artificially reduce the speed of the vehicle even when the vehicle enters the communication area, but also parking space. Traffic jams can be fundamentally solved at the entrance of the parking lot, which is a waste of considerable time to find. In particular, a large parking lot has a problem that female customers are easily exposed to crime due to the characteristics of the human beings. According to the parking management system and method of the present invention, an ID approval check is performed on a vehicle when entering a parking lot, and thus, the driver who is not authorized to move to the parking area. Entry is blocked off.

The present invention is a parking management system and method applying a short-range communication system using an RFID tag using a backscattering method in the ultra-high frequency (for example, UHF band, 2.4GHz, 5.8GHz) band. The present invention checks the ID of the vehicle by wireless communication between the RFID tag attached to the front or the front and the rear of the vehicle and the reader installed on the gantry or the ceiling, and then the tolerance status stored in the central control unit (computer). In the database that contains the information, the ID-checked vehicle generates a signal to guide the parking area, and the vehicle is led to the display (LED displayer, warning light). In large stores such as department stores, a small number of customers make up a large portion of sales, so it is also possible to assign special parking areas to customers who need special management. Parking management system and method of the present invention indicates the location of each floor through the display (LED displayer) at the entrance of the parking lot and when the arrival to the floor tells the code of the parking location (the corresponding parking booth in the parking cell). The arrival of the vehicle on the floor is detected by a reader installed at the entrance of the floor, and helps the driver to easily arrive at the parking booth through a display (light or LED display) near the location of the code.

Depending on the structure of the parking lot, there may be a need for the front parking or the rear parking of the vehicle. When the vehicle is detected by the vehicle detection sensor using a vehicle detection sensor (loop coil, piezoelectric sensor, etc.) but the tag is not detected by the reader, turn the vehicle. When a parking request is made through a small speaker, and a tag is detected, vehicle information about the corresponding parking is input to the central computer, and the parking residence time of the vehicle is counted thereafter. When the parking lot exits based on the residence time, the parking fee will be notified through the LED display and settled monthly or after a certain period. On the other hand, a reader is installed on the ceiling or in a specific area to continue real-time communication with the tags of the vehicles in the cell. It can not only understand the status of the tolerance, but also install it at the entrance of the parking lot or access to the parking lot such as an elevator based on the ID of the vehicle so that the driver can easily find the vehicle and forget the location of the vehicle that is common in large parking lots. The problem can also be solved.

Once again, the parking management system and method of the present invention, the parking management system of the present invention using the RFID tag and the reader unit guides the vehicle from the entrance of the parking lot through the induction display such as LED displayer to the reserved parking booth automatically. By dividing the entire parking area by the unit of parking cell and wirelessly communicating with the RFID tag of the parking vehicle in real time by several or dozens of readers, the data is collected in real time to obtain the tolerance status by wire or wireless (2.4GHz wireless). LAN or 424MHz wireless low power device) to transmit to the data collector of the central control unit (central computer). And the parking management system and method according to the present invention, after confirming the approval of each vehicle by the ID to guide the vehicle automatically to the proper position in the shortest time after the driver, the driver knows the vehicle parking position after the driver is out of the vehicle The driver can monitor at any time through the parking lot entrance display or the parking position guide display as shown in FIG. 9 in a specific area. In addition, the parking management system and method according to the present invention has several parking booths consisting of one parking cell in the structure of the parking cell. In order to make a database as a pair, the position and the ID of the vehicle must be mapped one-to-one, and in order to detect this more accurately, the Z-axis and the two-axis motor (or two motors composed of joints) as shown in FIG. Rotate constant speed and angle about X axis.

Hereinafter, a parking management system and method according to the present invention will be described in detail with reference to the accompanying drawings 3 to 11. In this case, the same reference numerals are given to the components that perform the same functions in FIGS. 3 to 11, and the components for the connection and input / output of the main elements in each drawing are briefly or omitted. The technical contents of the method will be omitted from the illustration and description of the components basically applicable to those skilled in the art, and illustrated and described based on the parts related to the present invention.

3 to 10 are views for explaining a parking management system according to the present invention.

3 to 10, the parking management system 10 according to the present invention includes a central control unit 20, an RFID tag 62 unit, a reader unit 30, 34, 36, 38, and a display unit 50. 52 and 54, a parking sensor 72, a parking position guide display 80 and the like. Basically, the parking facility to which the parking management system 10 of the present invention is applied is classified into a plurality of parking cells including a plurality of parking booths, and classified into at least one parking area including the plurality of parking cells. Here, the destination area corresponds to the parking lot on each floor. A passage is formed between the parking cells to allow the vehicle to move and a main passage is formed to allow the vehicle to move from the entrance to the parking area.

The central control unit 20 controls a parking management by mounting a database for managing a parking management program and a parking facility. The RFID Tag 62 unit is configured as shown in FIG. 10 and installed in a vehicle using a parking facility. The reader unit 30, 34, 36, 38 is composed of an entrance reader 30, a main passage reader 34, a passage reader 36, and a cell reader 38 so as to wirelessly communicate with the RFID tag 62. When 60) enters the parking facility, the entrance state of the vehicle is detected and transmitted to the central control unit 20 from the entrance of the parking facility to the parking booth where the vehicle parks. The display units 50, 52, and 54 are composed of a parking area induction display 50, a parking cell induction display 52, and a parking booth induction display 54. You will be guided to the designated parking booth. The parking sensor 72 is installed in the parking booth and detects whether the vehicle 60 has parked in the parking booth and transmits the same to the central control unit 20.

Here, the entrance reader 30 is installed at the entrance of the parking facility to detect the entry of the vehicle 60, the main passage reader 34 is installed at the main passage of the parking facility to detect the entrance of the vehicle to the parking area, The passage reader 36 is installed in the passageway of the parking area to detect the entry of the vehicle into the parking cell in the parking area, and the cell reader 38 is installed above the parking cell to provide the vehicle with the parking booth in the parking cell. Detect entry and exit. And the parking area induction display 50 is installed at the entrance of the parking facility to guide the parking area of the vehicle 60 in accordance with the transmission signal of the central control unit 20, the parking cell induction display 52 at the entrance of the parking area It is installed to guide the parking cell of the vehicle, the parking booth guide display 54 is installed at the entrance of the parking cell to guide the parking booth of the vehicle.

As shown in FIG. 10, the RFID Tag 62 unit applied to the parking management system of the present invention uses a short-range wireless packet communication system to receive power and modulated signals radiated from a reader by using a tag antenna to receive power. After driving the CPU and demodulating the modulated signal, the digital signal is processed by the CPU, and then another modulated signal to be sent to the reader, for example, ID information, is reflected on the carrier signal and sent to the reader. Here, the size of the reflected modulation signal varies depending on how far the RFID tag is from the reader. If the threshold is determined according to the distance class, the coordinates of the parking cell such as the matrix are determined. Through this, the ID information of the vehicle and the coordinate values in the parking cell are stored in the central controller 20. However, due to the structure of the parking lot, two motors are mounted at the end of the reader housing (some parts that can be integrated with the housing) to prevent incomplete scanning when the ceiling height is not high enough. Can help. Again, shielding must be installed to eliminate all sources of noise that may be generated by the motor. 4 is a view for explaining an example of a reader applied to the present invention. Referring to this, the reader unit is provided with a reader 302 configured to integrally combine two motors with a joint and rotate at a constant rotational speed and rotational angle about a Z axis and an X axis.

Referring to FIG. 3 again, the on-vehicle RFID tag 62 may be attached to the front or front and rear surfaces of the vehicle according to the parking situation. The wireless RFID tag 62 of the present invention can be attached to any position of the vehicle because no external power supply is required. However, since the antenna of the reader is directional, the radiated power and information signal radiated from the antenna of the reader may be used. In order to receive the tag well, the LOS should be a line of sight, so it is preferable that the tag be installed in parallel with the antenna of the gantry. However, if you use the RFID tag with built-in battery, it does not have to be in line with the antenna of the reader.

On the other hand, when the vehicle reaches a certain distance in front of the antenna 30 of the reader 30 at the entrance and exit of the parking lot, electromagnetic waves emitted from the antenna of the reader 30 in the gantry are attached to the front of the vehicle. After reaching the antenna, the IC chip (u-controller) is driven with the received power, and the demodulation signal is demodulated to process the information. The ID information stored in the IC chip is modulated and then backscattered and transmitted to the reader. As shown in FIG. 4, the antenna of the reader unit used in the present invention is an antenna having directivity. Therefore, since the detection area is limited and cannot cover one parking cell, it is necessary to scan the propagation direction of the reader to all the vehicles in the parking cell in order to cover one parking cell using one reader. . To this end, the reader has a motor driven integrally with two axes (or with two motors). The two axes consist of the X and Z axes in polar coordinates. Rather than moving in a combination of two axes at the same time, the upper row will be scanned first and the lower row will be scanned in the parking layout. Therefore, after rotating to the value of θ around the Z axis, the value of Φ around the X axis is rotated and the reverse process is performed again. FIG. 5 shows an example of X and Z-axis scanning for communication between a RFID tag and a reader of a vehicle parked in each parking booth in an arbitrary parking cell, but the present invention is not limited thereto. .

10 illustrates a communication relationship between a reader and several RFID tags in the parking management system of the present invention. Referring to this, since the reader and the tag use the TDD (time division duplexer) method and the half duplex mode, even if two or more tags are detected in one detection area, the tag responds to polling first and then the rest is processed. Will be processed. Therefore, the rotation speed is determined in consideration of this. Coding can be used in various ways, but here, ASK (amplitude shift keying) is used for downlink, and BPSK (binary phase shift keying) is used for uplink. The structure of the reader unit is divided into three stages. It consists of an MPU, a baseband packet modem that processes a digital modem, and an RF unit that transmits and receives a modulated signal on a carrier wave. At this time, the antenna is not divided into a patch antenna or a helical antenna, a dipole antenna. The RFID tag consists of a modem unit, an encryption unit, and a u-controller unit for demodulating a signal carried on a carrier wave. Depending on the situation, you can use a tag that consists only of memory without using the CPU.

In the present invention, the integrated reader having a two-axis motor is applied to the cell reader 38, and the detection area of the readers 34 and 36 installed in the main passage and the passage is continuously polled only for a certain region (non-rotating and fixed). polling). Whether all vehicles entering and exiting the main passage through the main passage enter the predetermined parking booth is determined through the reader 36 installed in each passage. At this time, the parking cell guide display 52 installed at the entrance of the main passage for each parking area (floor) identifies the vehicle ID at the entrance when entering and exiting the main passage for each parking area (floor), and then guides which path to be guided. In order to avoid confusion with the following vehicle, show the driver's parking reservation location by showing the driver's vehicle number or a specific unique code when showing the lane's induction light (green light when entering the entrance, red light when not entering). give.

On the other hand, when the vehicle enters the parking area is identified through another reader 36, the parking booth guidance display 54 installed at the entrance of each passage to finally position (parking booth) as shown in Figure 8 Tells the driver where to park. When the parking is completed, the parking situation is transmitted to the central control unit 20 in real time through continuous communication between the reader 38 on the parking cell and the RFID tag 62 of the vehicle. Therefore, information of all vehicles parked on the floor is stored in the database through the central control unit. For this reason, according to the parking management system and method of the present invention, it is possible to secure data for differentiated customized customer management, such as parking days and the number of parking, parking time.

In addition, the parking management system of the present invention has a parking sensor 72 installed in the parking booth and detecting whether the vehicle is parked in the parking booth and sending it to the central control unit 20. The parking sensor 72 is shown in FIG. Like the built-in piezoelectric sensor installed in the wheel stopper 70 for limiting the position of the wheels (64) of the vehicle 60 in the parking booth. And depending on the situation, an ultrasonic sensor may be installed on the top. If the ID signal is not received from the reader even though the detection signal of the piezoelectric sensor 72 indicating that the vehicle is currently parked in the parking booth is received by the central control unit 20, a warning message indicating that the reader of the cell is abnormal is displayed. Float on the control unit 20. This is a signal for fault diagnosis and requires repair.

Meanwhile, the parking management system according to the present invention may install the parking position guide display 80 as shown in FIG. 9 in a parking facility or a facility having a parking facility at a predetermined position. The parking position guide display 80 is connected to the central control unit 20, the window 82 showing the vehicle number, the window 84 showing the parking booth code, the window 86 showing the parking position, parking time, parking The window 90 and 92 which show parking information, such as time, and the keypad 88 for a parking person operation. The guide display 80 is connected to the database of the central control unit 20 to provide various information of the currently parked vehicle. In general, in a large parking lot, a driver often forgets the location of a parked vehicle when parked for a long time, and in such a case, not only can he spend a lot of time finding his car, but it can also become a potential complaint. In order to improve this, the parking location guide display (80) is installed at the entrance of the parking lot elevator or parking entrance entrance and enters his or her own vehicle number or unique code. It is to induce customer satisfaction by informing the inquirer of the parking lot entrance time and residence time.

11 is a flowchart illustrating a parking management method according to the present invention.

Referring to FIG. 11, the present invention drives an IC chip mounted on a tag while reflecting a carrier signal carrying power and modulation signals from a reader using ultra high frequency as a carrier wave to an RFID tag attached to a front glass or a front glass of a vehicle. The demodulation signal is then demodulated to process information. A reader is installed in the gantry of the parking lot entrance and exit (S100 to S120) so that the reader and the tag communicate with each other while the vehicle enters the entrance of the parking lot (regardless of the running speed or, in some cases, the normal driving speed). After that, the tag information received from the reader, that is, the information of the driver (vehicle), is transmitted to the central control unit (computer), and the central control unit compares the personal information of the driver (S170), and then the driver such as the wall or the ceiling of the parking lot is easily driven. The 7-segment is installed at a prominent position to display the ID of the vehicle, that is, the vehicle number, the ID which is a specific code indicating the owner, and the reserved parking area (by floor) to guide (S210 ~ S330).

This parking management method informs the designated parking area by a specific code (vehicle number, etc.), so that it does not cause any confusion to the driver of vehicles following from behind. In addition, when the driver comes up to the floor, the tag of the vehicle is detected by the reader installed at the entrance and exit of each floor, and the parking position in the floor is displayed through a code or a layout by sending and receiving data (S230 ~ S250). In addition, the reader is installed again at the lane entrance between each parking cell to determine whether the vehicle is arriving in position. When the vehicle is stopped at the parking booth in the corresponding parking cell, it is determined whether the parking is normally performed by the cell reader and the vehicle detection sensor (that is, when it is designated as the front parking lot or the rear parking lot) (S300). The computer stores information about the vehicle and the parking booth in the database (S330).

In the parking management method of the present invention, since the vehicle ID is transmitted to the central control unit and checked at the entrance of the parking lot, a vehicle that is not approved in advance may be notified to a safety officer in some cases, and thus, a female driver may be particularly affected by a serious crime. It has the advantage of protecting it. And when the new parking management system is introduced at department stores, luxury hotels, and large discount stores, differentiated customer satisfaction management will be possible by linking the purchase pattern or shopping taste of the driver who owns a vehicle-mounted RFID tag with this system.

Referring back to FIG. 11, the parking management method according to the present invention first supplies power to the parking entrance and exit, the main passage for each floor, the reader installed in each passage, and the reader installed on the parking cell (S100). Then, the parking cell supplies power to the motor and its control unit which are integrated in order to rotate the two axes of the reader (S110). The controller sequentially includes a program that rotates about the z-axis and then rotates about the x-axis. All the power supply is completed and enters the initial mode (S120). The power system diagram is displayed at the same time by the central control unit so that the administrator can view it. If no power is supplied, an emergency message appears in the central control unit (S130). After the initial mode, the reader and various displays are reset and operate normally, and the reader at the entrance and exit of the parking lot, the reader at the main passage by floor, and the reader of the parking cell radiate transmission power and information signals for data communication. When the vehicle enters the entrance of the parking lot, it tries to communicate with the reader to check whether the ID is approved (S140). In this case, the vehicle enters the vehicle through a vehicle detection sensor (reference numeral 40 of FIG. 3), for example, an infrared sensor, but the vehicle entry is checked (S150), but when the ID check is not performed, a warning message is notified to the driver and known to safety personnel. Received or a separate action is taken (S180, S190). After checking whether the ID is approved (S170), when the vehicle proceeds, the ID information is transmitted to the central control unit (S200) to identify the tolerance status on each floor and informs the corresponding floor and vehicle number through the parking area guide display (S210). . This display is shown by a timer of a predetermined time (S220). When entering the floor is detected by the main passage reader installed in the main passage by floor again (S230). This determines whether the driver has entered the floor according to the instruction (S240). In addition, if the parking lot main entrance tells the information about the planned parking place, it will be forgotten on the way and may increase the confusion and safety accidents. Therefore, when detected by the reader in the main passage tells which path to approach through the parking cell induction display (S250). Approaching the corresponding passage through the main passage is detected again by the passage reader installed in each passage and shows a code for informing the parking booth through the parking booth guide display (S280). Therefore, the driver finally checks the code painted on the floor of the parking booth and parks the vehicle. At this time, it is determined whether the parking vehicle is properly parked according to whether the piezoelectric sensor built in the wheel stopper on the parking floor is detected (S310). This prevents accidents coming into contact with adjacent vehicles in advance. When the wheel of the vehicle does not touch the wheel stopper properly, it gives a warning sound or a message to help you park properly (S320). When the parking is completed, the driver gets out of the vehicle and at the same time, the cell reader installed in the parking cell is continuously rotated at a certain angular speed with respect to the Z and X axes to communicate with various tags.

Parking management method according to the present invention is to enter the parking lot by installing the antenna of the reader in the direction of each entrance or entry entrance to the gantry (gantry) installed in the parking lot entrance in a large parking lot, such as department stores After wireless communication with the reader, confirm the registration of the vehicle, and when entering, the parking area is displayed to the driver by driving the timer for a predetermined time. At this time, the vehicle is detected by the vehicle detection sensor, but the unregistered vehicle or the vehicle without the tag is directed to a separate parking area by receiving a separate instruction from the safety officer (or the administrator in charge of the real-time parking status of the central control unit). Be sure to If there is no tag or registered in the parking lot for members only, access is not allowed. The display also turns on and off by setting a certain time as a passing time depending on the terrain of the parking lot. When the vehicle arrives at the parking area and parks the vehicle, the reader and tag communicate wirelessly. Since the parking management method of the present invention employs a time division multiple access method between the reader and the tag, the tag of all vehicles parked in the parking cell in a very short time (usually dozens to hundreds of tags and data can be transmitted within one second). Communicate Of course, since the directional antenna is used, the two-axis motor rotates to communicate with each vehicle. If a split beam antenna is used here, a two-axis motor is not necessary. In addition, the central control unit stores the ID information of all vehicles parked in the database, and when the driver enters his / her vehicle number (or the specific code) at the entrance of the parking lot, elevator platform, or a specific area, the location of the vehicle is real-time. Shows. In addition, it is possible to fundamentally prevent errors due to double allocation to a specific parking booth because the vehicle is detected after the tolerance state is first identified in the initial mode of the system. Here, the communication between the reader and the central control unit can be either wired communication or wireless communication (for example, 2.4GHz wireless LAN, 400MHz wireless device), but wireless communication is desirable considering the parking environment. ID information in the parking cell and data on the parking location are organized in pairs and stored in the database. At this time, when the reader scans at a predetermined angle, the detection area is minimized so that only one vehicle can be detected in the detection area. Therefore, from the installation of the parking cell reader, the geometrical configuration with the parking cell is analyzed and the corresponding parking booth per angle increment is preset.

Such a parking management system and method according to the present invention makes it possible to park in the shortest time to waste a lot of time because it does not find a delay and a parking space due to the issuance of a parking ticket when entering the parking lot. In addition, it is possible to maximize the use of the parking space by preventing the square parking space caused by the selection of the parking booth by the driver's one-sided judgment. And even if a driver who is out of the parking vehicle forgets the parking position of his vehicle, the parking position of the vehicle can be provided through the parking position guide display installed in a specific area. In addition, the parking management system and method of the present invention can be protected from crime because the female driver can use the member parking lot because the user can know whether or not the prior approval of the own weight through the tag.

As described above, the parking management system and method according to the preferred embodiment of the present invention has been shown in accordance with the above description and drawings, but this is merely described for example and various changes without departing from the spirit of the present invention. And those skilled in the art will appreciate that changes are possible.

According to the present invention, not only can maximize the use efficiency of a large parking lot in department stores, discount marts, etc., but also to improve the time loss caused by issuing a parking ticket when entering the parking lot and the time loss consumed to find a parking space. In addition to eliminating customer complaints caused by congestion, it is possible to reduce the number of parking personnel to reduce operating costs. In addition, it can provide a service for the parking location, so that customers can immediately feel satisfied when they forget the parking location, and when entering the facilities of the parking lot that requires any qualification, such as a member-only parking lot or a women-only parking lot, Automatic guidance without the need for friction.
