<Parking position determination and storage>

Determination and storage of the parking position in the parking management system of the present invention proceeds as follows, will be described with reference to FIG.

First, while the vehicle # 1 passes through the radio frequency transceiver # 0 installed at the parking gate or the parking lot vehicle entrance, the vehicle attachment tag attached to the vehicle is recognized and the movement path is tracked.

At this time, when the sensing unit included in the radio frequency transceiver (# 0) detects the passage of the vehicle # 1 and generates a detection signal, the wakeup unit transmits the wakeup signal, and the vehicle attachment tag that receives the wakeup signal is Is activated and wireless communication is performed. In addition to the information on the user and the vehicle stored in the radio communication, the ID of the radio frequency transceiver (# 0) transmitting the wake-up signal is transmitted together. The radio frequency transceiver (# 0) receiving this is transmitted to the system control unit 15 via the repeaters and stored in the data storage unit 13.

Subsequently, when the vehicle # 1 passes through the radio frequency transceiver # 4, radio communication is performed in the same manner as in the radio frequency transceiver # 0 as described above.

Subsequently, when the vehicle is parked in a parking unit compartment, the vehicle # 1 no longer receives the wakeup signal. In such a state, after a predetermined time, for example, 5 seconds to 10 seconds, the vehicle attachment tag wirelessly transmits a parking completion signal.

The radio frequency transceiver 12 receives the parking completion signal and transmits it to the system controller 15. The system control unit 15 receives this and stores the parking position of the vehicle # 1 in the data storage unit 13 as parking identifiers 7 and 13. At this time, the system controller 15 may determine that the vehicle # 1 is parked on the side of the radio frequency transceiver # 4 among the radio frequency transceiver # 4 and the radio frequency transceiver # 5 using the RSSI. have. At the same time, the system controller 15 may control to transmit the determined parking position, that is, the parking identification codes 7 and 13, to the user portable tag connected to the vehicle. The user portable tag receives and stores it.

In other words, the vehicle attachment tag receives the wake-up signal transmitted from the radio frequency transceiver 12 installed at the entrance of the parking lot in the sleep mode and becomes the active mode. The ID of the wake-up unit included in the wake-up signal is checked, and if it is a valid ID, the ID of the vehicle attachment tag and the ID of the wake-up unit are transmitted together through the wireless transceiver. After the transmission is completed through the wireless transceiver, the device enters the sleep mode again.

When the vehicle tag does not receive the wake-up signal of the radio frequency transceiver after a certain time after receiving the wake-up signal or continuously receives the ID of the same wake-up unit, it is determined that the vehicle is parked. After transmitting the 'parking completion signal' by using, repeatedly enters the 'parking position confirmation' message several times and enters the sleep mode.

All data transmitted by the wireless transceiver of the vehicle attachment tag is received by the radio transceiver of the radio frequency transceiver installed in the underground parking lot, and the received data is immediately stored through the repeater and the main repeater and stored in the data storage unit.

The system controller checks the ID of the vehicle attachment tag that sent the message when the 'parking completion report' message is confirmed among the data received from the main repeater.

When the ID of the vehicle attachment tag is confirmed, the system controller analyzes the ID of the radio frequency transceiver of the wake-up signal received by the vehicle attachment tag from the data received from the tag in chronological order and transmits and receives radio frequency in the parking lot. Determine the parking location identification area distinguished by the device.

Next, find the 'Parking Location Confirmation Report' message sent repeatedly several times after the parking completion report by the same vehicle attachment tag and determine the smaller area within the area determined above by using the RSSI values received in the message. Register the area in the data store. In the case of the vehicle # 1, it will be the parking location identification area indicated by the parking location identification code 7-13.

When a new parking position is registered, the system controller may transmit the parking position information to a radio frequency transceiver installed in all common entrance halls accessible to the vehicle owner.

On the other hand, in the case of the active tag to take as long as possible to use the battery replacement cycle to prolong the user's convenience. In this case, instead of transmitting the radio frequency transceiver and the tag's own ID immediately after receiving the wake-up signal, the tag is included in the 'Parking completion report' or 'Parking location check' message, thereby reducing the number of times and the transmission time of the tag. You can have a longer battery replacement cycle.

In the case of the ground parking lot, it is difficult to install a plurality of radio frequency transceivers.

If the vehicle does not receive the wake-up signal from the radio frequency transceiver installed at the entrance of the underground parking lot after a certain time after receiving the wake-up signal from the parking control access controller at the entrance of the vehicle, the tag attached to the parking lot Acknowledge the message periodically and confirm the response signal. If the tag attached to the vehicle receives a wake-up signal or a response signal for the 'check parking location' message from the same receiver for a predetermined number of times, it is determined that there is no movement of the vehicle and transmits a 'parking completion report' message using the wireless transceiver. After entering the parking lot confirmation message several times, the system enters the sleep mode. In more detail, in the case of the underground parking lot, it may be determined that parking is completed when the wakeup signal is not received for a predetermined time or when the same wakeup signal is received from the same wakeup device for a predetermined number of times. In the case of the ground parking lot, when the response signal for the parking position confirmation message is received from the same receiver for a predetermined number of times, it may be determined that parking is completed. The system controller may register the parking available parking area as the parking location using only the RSSI value of the tag 'parking location confirmation' message using the tag data uploaded from the radio frequency transceiver through the repeater and the main repeater.

<Delete and change parking information>

When the vehicle registered with parking information starts to move, it detects it and sends a wake-up signal, and the vehicle attachment tag receives the wake-up signal and is operated again by the location recognition algorithm of the underground parking lot. Data is stored in DB.

When the vehicle is moved to a new parking location after moving, the vehicle sends a 'parking completion report' message, and then repeatedly sends a 'check parking location' message several times to enter the sleep mode.

If the vehicle moves out of the parking lot, the information of the tag attached to the vehicle is received by the RF transceiver installed at the entrance of the parking lot and transmitted to the system controller. It is found to be invalid.

Then, when the information of the vehicle attachment tag is received by the radio frequency transceiver installed only at the entrance, it is recognized that the vehicle corresponding to the vehicle attachment tag is completely out of the complex and deletes the registered parking information and stores the departure information.

<Parking information guidance>

The system of the present invention performs an operation of automatically guiding the parking information including the parking position when the user is directed to the parking position.

For example, when a user carrying a user's portable tag passes through a parking lot entrance, the system recognizes this and performs a guide operation by voice or visual display through a guide unit close to the user. Therefore, the system controller first determines whether the user is headed to the parking position, and controls the guide to perform the guide operation.

As described above, the determination that the user is headed to the parking position may be recognized when the user passes through the front entrance of the parking lot or may be recognized when the user passes through the specific area.

When the user's mobile tag connected to the vehicle attachment tag registered with parking information receives the wake-up signal from the radio frequency transceiver installed in the common entrance and performs radio communication, the radio frequency transceiver checks and registers the parking information of its own. If there is parking information, the information is transmitted to a guide unit (display device) installed outside.

At this time, the radio frequency transceiver can inform the parking information to the voice guide in case the user does not have a separate parking indicator or can not check the indicator.

Parking information voice notification by the radio frequency transceiver can be used by the user as follows.

In the case of unconditional notification in the parking information voice notification service, as shown in FIG. 5, when the user's mobile tag is installed in the common entrance as the basic operation mode of the system, the user receives the wake-up signal of the radio frequency transceiver. The mobile tag transmits its ID to the radio frequency transceiver. The radio frequency transceiver having received the ID of the user's mobile tag checks whether the location information of the vehicle connected to the received user's mobile tag is registered among the parking positions received from the server in advance. If there is registered information, the location is notified to the user using the voice guide as parking information. Speech comments should be as concise as possible to minimize delays when used by multiple users. For example, '0000 vehicle is parked in the X-X area'.

There may be a case where the user only notifies the parking information voice notification service. This is the default setting available for your configuration or system. For example, when a user carries a user's mobile tag and presses or presses a button of the user's mobile tag in advance near the common entrance RF transceiver, the user's mobile tag transmits its ID or parking information by using the wireless transceiver. Deliver to frequency transceiver.

The radio frequency transceiver receiving this information checks the signal of the user's portable tag transmitted by the button of the user's portable tag, and provides the parking information notification service only by the user in this case.

If the parking location of the vehicle connected to the ID of the user's portable tag is registered in the memory embedded in the RF transceiver, the voice guide unit informs the location.

If the parking location of the vehicle connected to the user's portable tag ID is not registered, the requested user ID information is transmitted to the system controller and the newly registered parking location is checked. If there is a newly registered parking location, the information should be immediately informed by the voice guide. If there is no registered parking information, the voice guide must be notified.

There may be a case where the parking information voice notification service is not used. This can be set by the user for his or her privacy. If the radio frequency transceiver receives the ID of the user portable tag thus set, the radio frequency transceiver does not guide the parking information.

For the efficient parking location identification section, the radio frequency transceiver can be implemented as follows.

A column is used to mark the parking location identification block with an identification code, in which case one column or two columns can be used.

The location of the RF transceiver can be set in various areas according to its location when the RF transceiver is installed on the ceiling. However, it is most efficient to install the RF transceiver. In this case, when the intersection is wide, it is advantageous to install and operate two radio frequency transceivers.

In addition to wide intersections, when the distance between the RF transceiver and the RF transceiver is too long, or when a more precise location area is required, additional RF transceivers can be installed to increase accuracy and system reliability.

The marking by the pillars relates to the parking positioning, which is a common method of storing parking positions. In order to determine the final position, at least one radio frequency transceiver ID including the ID of the radio transceiver having passed last time and the RSSI value by the 'parking location confirmation' message are required.

At least one area is determined by the radio frequency transceiver for parking location determination, and then the radio frequency transceiver having the highest RSSI in the 'Parking Location Confirmation' message is found. In the cross-shaped intersection, there will be four pillars, two of which are included in the area defined by the radio frequency transceiver, and two pillars corresponding to the passage will be stored and displayed as the final position.

In FIG. 4, in the case of vehicle # 4, the parking position that can be determined when the radio frequency transceiver # 6 is finally passed and the value of RSSI is the highest when the radio frequency transceiver # 9 is the highest. In the area of the parking compartment identification area associated with the radio frequency transceivers # 6 and # 9, the pillars closest to the radio frequency transceiver # 9 are 24 and 34.

An exceptional case is where the vehicle # 5-1 is located in FIG. 4, where the 'L' shaped passage passes through the radio frequency transceiver # 2 and the RSSI of the 'Parking Location Confirmation' message transmits and receives the radio frequency. Since only one column can be determined when the device (# 3) is the highest, only the parking position identification code 6 is stored.

When there are two or more stored parking location identification codes, the user may be able to guide the identification codes that are easily seen within the set range of the parking lot pedestrian entrance 18 of FIG. 4 or the like for efficient guidance to the user.

When the user who has completed the parking as shown in FIG. 5 approaches the door lock 12, which is a radio frequency transceiver for a common entrance or a radio frequency transceiver for a generation entrance, there is a parking position received from the system controller in each device. The mobile tag can tell the parking location.

When the user presses a button on the user's mobile tag to exit the front door of the household and go to the parking lot, the tag transmits the parking location information of the user to the receiver through the wireless transceiver to the radio frequency transceiver installed in the elevator. (FIG. 6). When the receiver installed in the elevator receives this signal, the parking position is notified to the user through the built-in voice guide unit 141 or the display device 142 installed in the elevator. The devices installed in these elevators to receive and guide the parking information from the user portable tag may be referred to as parking information display devices. However, the present invention is not limited thereto, and the guide device connected to all the wireless transmission / reception apparatuses may include a function of receiving and displaying parking information from the user portable tag.

In addition, the user tag of the wireless recognition unit employed in the present invention includes a passive portion, the user can access the receiver provided when necessary, and can perform operations such as guidance (confirmation) of the parking position or automatic input of the elevator push button. .

<Use of Near Field Communication>

Automatic storage and guidance of the parking position of the present invention can be conveniently confirmed by the other portable terminal of the user using the NFC method.

For example, as shown in FIG. 7A, the wireless recognition unit (user tag) 11 may include a 13.56 MHz smart IC 16. In this case, the NFC portable terminal 110 may exchange information regarding parking through short-range communication. As described above, when the information regarding the parking is stored in the wireless recognition unit, the wireless recognition unit 11 of FIG. 7A is approached to the parking stored in the wireless recognition unit 11 by a simple operation of approaching the user portable terminal 110. The information may be transmitted to the user portable terminal 110. In this case, it can be seen that the user portable terminal 110 performs a role of a reader. In this case, not only does the packet consumption occur at all, as in the conventional method using the public network or the Internet network, but the user can check the information on the parking at any time using the mobile terminal 110 such as a smartphone.
