In addition, Zigbee alliance was formed with consumer electronics companies related to sensor networks and home networks, and research on higher protocols including routing algorithms has been actively conducted by adopting IEEE 802.15.4 as a physical layer and MAC function in Zigbee. .

Meanwhile, in order to realize a ubiquitous world, it is important to secure frequency resources according to new services capable of transmitting data at high speed. The emerging ubiquitous consensus is IEEE 802.15.3 UWB wireless communication, an HR-WPAN technology. Currently, active research is being conducted to commercialize UWB mainly in the United States, and patent applications for related technologies are exploding.

The present invention uses the WPAN technology to determine the location of the vehicle, and through this provides parking information, the parking management method that allows the driver to perform a faster and more accurate parking while consuming less power than conventional methods It is an object of the present invention to provide an apparatus and a system.

The objects of the present invention are not limited to the above-mentioned objects, and other objects and advantages of the present invention, which are not mentioned above, can be understood by the following description, and more clearly by the embodiments of the present invention. Also, it will be readily appreciated that the objects and advantages of the present invention may be realized by the means and combinations thereof indicated in the claims.

According to an aspect of the present invention, there is provided a parking management method, comprising: transmitting one or more beacon signals including vehicle identification information according to a preset transmission period, and beacons transmitted from a vehicle corresponding to the vehicle identification information. Receiving a response signal to the signal, acquiring the location information of the vehicle using the response signal and the stored parking lot coordinate information, and providing the parking information to the vehicle using the location information. do

In addition, the present invention provides a parking management apparatus, comprising transmitting at least one beacon signal including the vehicle identification information according to a preset transmission period, and receiving a response signal for the beacon signal transmitted from the vehicle corresponding to the vehicle identification information And a location information acquisition unit for obtaining location information of the vehicle by using a transceiver, a response signal, and previously stored parking lot coordinate information, and a parking information provider for providing parking information to the vehicle using the location information.

According to the present invention as described above, there is an advantage that allows the driver to perform the parking faster and more accurately while consuming less power than conventional methods in managing the parking of the vehicle entering the parking lot.

The above objects, features, and advantages will be described in detail with reference to the accompanying drawings, whereby those skilled in the art to which the present invention pertains may easily implement the technical idea of the present invention. In describing the present invention, when it is determined that the detailed description of the known technology related to the present invention may unnecessarily obscure the gist of the present invention, the detailed description will be omitted.

The present invention relates to a parking management method, apparatus, and system, and uses a map information of a parking lot previously stored and a beacon signal by WPAN technology to determine a location of a vehicle entering a parking lot, Providing parking information enables vehicle drivers to use parking facilities more quickly and conveniently. Here, 'parking information' is a 'parking guide information' that provides a parking space of the parking lot where the vehicle entered and the location of the car's parking lot together, and the driver who parked the car to find his parked vehicle again When the concept includes a 'parking place information' that provides information about the parking place of the vehicle.

In the case of existing parking facilities, it is difficult to know exactly where the empty parking space is located, so the driver spends a lot of time finding a parking space. In addition, after finding the empty space and completing the parking, after completing the work, he has to come back to the place where he parked. If the parking facility is large, it is difficult to find where he parked the vehicle. SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and the above-mentioned problems can be solved by determining the location of the vehicle after the vehicle enters the parking lot and using the same to provide parking information to the vehicle.

In addition, the present invention uses a beacon signal according to WPAN technology such as Ultra Wide Band (UWB), Bluetooth, ZigBee, etc. to determine the location of the vehicle. In order to determine the position of an object, the frame is transmitted to the object in the past. When the frame is transmitted, power is emitted higher than usual, which increases the power consumption of the entire system. However, when the location of the vehicle is determined using the beacon signal as in the present invention, it is possible to increase or decrease the radiated power according to the transmission period, and thus it is possible to identify the location of the vehicle with lower power.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the drawings, the same reference numerals are used to indicate the same or similar components.

1 is a configuration diagram showing the configuration of a parking management apparatus according to an embodiment of the present invention.

As shown in FIG. 1, the parking management apparatus 102 according to the present invention includes a transceiver 104, a location information acquisition unit 106, and a parking information providing unit 108. In addition, although not shown in FIG. 1, the database may further include a database storing parking lot coordinate information or the like, or may be connected to an external database.

First, the transceiver 104 transmits one or more beacon signals including vehicle identification information according to a preset transmission period, and receives a response signal for the beacon signal transmitted from the vehicle corresponding to the vehicle identification information. .

According to an embodiment of the present invention, a vehicle entering a parking lot is issued with a tag for identifying each vehicle and receiving parking guide information. The transceiver 104 periodically broadcasts or transmits a beacon signal to provide the parking guidance service, and the beacon signal carries vehicle identification information (eg, a vehicle identification code) for identifying each vehicle. . After receiving the beacon signal, the tag mounted in each vehicle transmits a response signal when receiving the beacon signal matching the identification information of the corresponding vehicle, and the transceiver 104 transmits the response transmitted for each vehicle. You will receive a signal. The response signal thus transmitted is used by the position information acquisition unit 106 to be described later to determine the position of the vehicle. Meanwhile, the transceiver 104 and the tag may use a WPAN communication method including UWB, Bluetooth, and Zigbee.

The location information acquisition unit 106 acquires location information of the vehicle by using the response signal received by the transceiver 104 and previously stored parking lot coordinate information. As described above, a database may be connected to the inside or the outside of the parking management device 102. The database stores map information on the corresponding parking lot, and the map information includes coordinate information of each parking spot. The database also includes distance information from the reference point (for example, the place where the parking management device 102 is installed) to each coordinate point. Based on the distance information and the transmission speed of the beacon signal, it is possible to predict the signal response time for each coordinate. The location information acquisition unit 106 compares the signal response time for each of the previously stored coordinates with the response time of the response signal actually transmitted from each vehicle, and the vehicle which transmitted the response signal is located at a certain position (coordinate) of the parking lot. You can see if it is. A location acquisition process of the location information acquisition unit 106 will be described in more detail with reference to FIG. 2.

The parking information providing unit 108 serves to provide parking information to the corresponding vehicle by using the location information acquired through the location information obtaining unit 106. As described above, 'parking information' can be largely divided into 'parking guide information' and 'parking place information'.

Priority parking guidance information refers to information about the current location in the parking lot of the vehicle and the available parking space in the parking lot from when the vehicle enters the parking lot until the parking is completed. The parking information providing unit 108 provides the vehicle with a map in which parking spaces in the current parking lot are displayed together with all parking areas of the parking lot. In addition, since the current location of the vehicle is displayed on the map, the driver can determine where the vehicle is located and where the nearest parking space is located. Such information may be provided through the Internet or a wired / wireless terminal (eg, a mobile phone). If a driver selects a place to park on a map provided by the driver, a service such as an arrow may be provided according to the route. .

When the driver completes the parking by providing the parking guide information, the parking information providing unit 108 determines the parking position of the vehicle and stores it in the database as the parking place information. It is possible to determine that the parking of the vehicle is completed with the help of the location information acquisition unit 106. The position information acquisition unit 106 periodically transmits a beacon signal and continuously identifies the position of the vehicle through the response signal from the vehicle (tag). If it is confirmed that the vehicle exists at the same position for a certain time, This may determine that the vehicle has completed parking. The parking information providing unit 108 then stores information about the parking place of the vehicle. (This information may be used to provide parking guidance information for other vehicles.) Afterwards, when a driver requests parking place information by using a tag or a terminal to determine the location of his / her parked vehicle, parking information The providing unit 108 may provide the driver with the stored parking place information of the vehicle through the Internet or a wired or wireless terminal.

2 is a view for explaining a scenario of a parking management method according to an embodiment of the present invention and a method for locating a vehicle.

In FIG. 2, an AP 102 represents a parking management apparatus 102 according to the present invention described with reference to FIG. 1. And 202 to 228 represent each parking space inside the parking lot. Now, a scenario of a process of parking a vehicle entering a parking lot will be described with reference to FIG. 2.

First, the driver drives his vehicle to enter the parking lot. And at the entrance of the parking lot, the process of billing, etc. is performed, and a tag for receiving a vehicle recognition and parking information provision service is issued. The tag may include vehicle identification information for recognizing the vehicle.

In the parking lot, an AP 102 is arranged as shown in FIG. 2. In the present embodiment, only one AP 102 is shown for convenience, but one or more APs may be installed depending on the size and other circumstances of the parking lot. In addition, the tag issued to the AP 102 and the vehicle uses a WPAN communication method including UWB, Bluetooth, and Zigbee, and the position of the AP 102 may vary according to the signal emission range of the antenna.

Meanwhile, map information of the parking spaces 202 to 228 is stored in a database (not shown). Here, the estimated signal response time for each coordinate is stored along with the coordinate information for each parking space from the reference point (AP 102 in FIG. 2). For example, in the case of the parking space 204, it is located in 3 m horizontal and 4 m vertical coordinates from a reference point. Therefore, the distance from the AP 102 to the parking space 204 is 5 m. And if the transmission speed of the beacon signal to be transmitted from the AP 102 is c, the signal response time in the parking space 204 can be estimated as the distance divided by the speed, that is, 5 / c. In this way, an expected signal response time for each of the parking spaces 202 to 228 coordinates is calculated and stored together with the parking lot coordinate information.

The vehicle issuing the tag now enters the parking lot. The AP 102 periodically transmits a beacon signal, which includes vehicle identification information for distinguishing each vehicle. (The transmission period of the beacon signal may vary depending on the setting.) When the transmitted beacon signal is received through a vehicle (tag) inside the parking lot and receives a beacon signal that matches the given vehicle identification information, each tag is assigned to it. The response signal is sent to the AP 102.

The AP 102 receiving the response signal may calculate the time taken from receiving the corresponding beacon signal to receiving the response signal, that is, response time of the response signal. The AP 102 may then determine where the vehicle is currently located in the parking lot by comparing the calculated response time with coordinates for each signal response time stored in the database.

The AP 102, which has obtained the location information of the vehicle, provides a map of the parking lot and information on the available parking space and parking guidance information indicating the current location in the parking lot of the vehicle through the driver's mobile phone or navigation device. do. In this case, the parking guide information may include information on the parking space closest to the current parking position along with information on a path (marked by an arrow or a distance) to the parking space. The parking guidance information provided allows the driver to determine the available parking spaces and complete the parking more quickly.

Since the driver 102 moves to park and then completes parking, the AP 102 periodically transmits a beacon signal, so that the location of the vehicle can be continuously determined. If it is determined that the vehicle is present at the same location for a certain time, the AP 102 determines that the vehicle has completed parking, and stores parking place information on the space in which the vehicle is parked in the database. .

After parking, the driver can be provided with information about where the vehicle is parked. The driver requests the AP 102 to provide a parking place by using a mobile phone or an issued tag. The AP 102 then provides the stored parking place information through the driver's mobile phone. If the driver has a tag, the driver may find the parked vehicle more easily by providing information about the driver's current location along with the parking place information of the vehicle.

The driver who knows the location of the vehicle leaves the parking lot. At this time, through the AP 102, the driver can reach the exit more quickly by being provided with information about the location of the current vehicle and the location of the parking lot exit, and can exit the parking lot after returning the tag.

Although not shown in FIG. 2, such a parking management scenario according to the present invention may be configured as a system. Such a system includes a parking tag management unit that manages issuance and retrieval of a parking tag including vehicle identification information, a database storing parking lot coordinate information in which signal response time of each coordinate of the parking lot is recorded, and a parking tag according to a preset transmission period. By using the location information acquisition unit and the location information to transmit a beacon signal, to receive a response signal for the beacon signal from the parking tag, and to obtain the location information in the parking lot of the vehicle using the parking time coordinate information and the response time of the response signal It may include a parking information providing unit for guiding a parking available space for the vehicle to park and for providing parking place information of the vehicle when the vehicle has completed parking. The parking tag and location information acquisition unit uses a WPAN communication method including UWB, Bluetooth, and Zigbee. In addition, the parking information providing unit performs the parking space guidance or the parking place information provision through the Internet or a wired or wireless terminal.

3 is a flow chart for explaining the flow of the parking management method according to an embodiment of the present invention.

First, at least one beacon signal including vehicle identification information is transmitted according to a preset transmission period (302). When more than one vehicle enters the parking lot, the location of each vehicle may be determined by transmitting a beacon signal including vehicle identification information at different periods. In addition, the transmission period of the beacon signal is set differently for each vehicle, it may be easier to distinguish the vehicle.

Next, a response signal for each beacon signal transmitted from the vehicle corresponding to the vehicle identification information is received (304). Then, the vehicle obtains location information of the vehicle by using the received response signal and previously stored parking lot coordinate information (306). Since the process of obtaining the location information of the vehicle has been described above with reference to FIGS. 1 and 2, a detailed description thereof will be omitted.

Then, the parking information is provided to the vehicle using the obtained location information (308). As mentioned above, the parking information is largely divided into parking guide information and parking place information. Information on providing parking information has also been described above, and thus a detailed description thereof will be omitted.

According to the present invention, by using a beacon signal of the WPAN method that can control the radiation power has an advantage that can provide the parking information using a lower power than the conventional method. In addition, the use of such a system has the advantage that it is possible to build an unmanned parking management system that does not require parking management personnel. In addition, operators can create a new revenue structure by linking these systems with the Internet or wired / wireless terminal services.

On the other hand, from the driver's point of view, by being provided with the parking management service according to the present invention, a faster parking is possible, and a place where his vehicle is parked can also be found more quickly. This speeding up of parking permits the side effect of reducing the vehicle's fuel consumption and improving the atmosphere.

The present invention described above is capable of various substitutions, modifications, and changes without departing from the spirit of the present invention for those skilled in the art to which the present invention pertains. It is not limited by.
