The present invention relates to providing roadside parking space information. More particularly, the present invention provides a function of detecting a roadside parking space to a vehicle in operation to identify a parking space available at the roadside in real time, and provides the same to a user in a corresponding area. Therefore, the present invention relates to a roadside parking space information providing method and a system for quickly grasping a roadside parking space that can be parked.

(Home Automation), Smart Metering (Smart Metering), etc. are widely used and are very important. In particular, when the traffic congestion and parking problems in the city are serious, the M2M traffic / vehicle field is more utilized.

Regarding parking, in a crowded city center, the driver continues to look around the city streets to find parking spaces close to the destination. This leads to waste of time and energy loss.

Existing parking management system operates as a system installed in a specific building and parking lot, but roadside parking space management system is insufficient.

In order to solve this problem, when there is a fixed parking space on the roadside, a solution for collecting parking space information from the center has been proposed by installing an embedded sensor on the floor.

Other objects and features of the present invention in addition to the above objects will be apparent from the description of the embodiments with reference to the accompanying drawings.

Preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In describing the present invention, when it is determined that the detailed description of the related well-known configuration or function may obscure the gist of the present invention, the detailed description thereof will be omitted.

Hereinafter, a method and a system for providing roadside parking space information according to an embodiment of the present invention will be described in detail with reference to FIGS. 2 to 7.

2 shows a configuration of a roadside parking space information providing system according to an embodiment of the present invention.

Referring to FIG. 2, the roadside parking space information providing system includes a detection vehicle 210 and an information providing server 220.

Here, at least one detection vehicle 210 may be set for each region. The detection vehicle according to the present invention includes an algorithm for detecting a roadside parking space, an ultrasonic sensor for detecting a roadside parking space, When a parking side parking space that can be parked is detected, a GPS receiver for obtaining location information of the corresponding street parking space and a camera for capturing an image may be provided.

In order to detect roadside parking spaces that can be parked in a detection vehicle in order to provide roadside parking space information in the present invention, a reference value for initially detecting roadside parking spaces may be different because the width of the roadside parking space may be different for each region or area. In the present invention, it is preferable to set the threshold value.

That is, the detection vehicle 210 initially traverses the roadside parking space of the corresponding area, calculates the distance to the roadside by using an ultrasonic sensor, and collects all calculated distance values for the roadside parking space of the corresponding area. Set a threshold for determining the available parking space on the roadside.

In this case, the threshold may be set directly in each detection vehicle collecting the distance values, or may be set in the information providing server 220. The vehicle may have a different threshold value, and when the information providing server 220 is set, for example, the information providing server 220 receives the distance values collected from the at least one detection vehicle, and uses the collected distance values. By calculating the threshold value and transmitting it to the detection vehicle of the region, all the detection vehicles of the region may have the same threshold value.

The detection vehicle 210 detects a roadside parking space that can be parked while moving in real time after the threshold is initially set. When the distance value calculated using the ultrasonic sensor while moving is greater than or equal to the threshold for a predetermined length or time, The area is detected as a parking space on the roadside.

Here, the preset length or time for determining the roadside parking space may be determined by counting the calculated distance value, or may be determined by other possible methods, which may be determined by the operator providing the service. Can be.

In addition, the detection vehicle 210 provides the location information and the image information of the space to the user by providing the location information using the GPS receiver and the image of the space photographed by the camera to the information providing server when detected as a roadside parking available space. To provide.

Such a detection vehicle will be described in more detail with reference to FIGS. 3 and 4.

FIG. 3 illustrates an embodiment configuration of the detection vehicle shown in FIG. 2.

Referring to FIG. 3, the detection vehicle 210 includes a collecting unit 310, a setting unit 320, a detecting unit 330, and a transmitting unit 340.

The collection unit 310 sequentially collects distance values to the roadside calculated by the ultrasonic sensor 350 while traveling the roadside parking space in the corresponding area of the detection vehicle.

That is, the collecting unit 310 collects data for setting a threshold for detecting a roadside parking space, and transmits from the ultrasonic sensor 350 while the detection vehicle circulates in a lane farther away from the roadside parking space. The distance values to the roadside are calculated and collected using the reflected values of the ultrasonic signals.

The setting unit 320 is configured to set a threshold value for determining a parking space on a roadside of a corresponding area by using the distance values collected by the collecting unit 310, but may use all collected distance values. Only distance values corresponding to a certain range of the distance values may be extracted, and a threshold may be set using only the extracted distance values.

In this case, the setting unit 320 may calculate an average value of the extracted distance values and set a threshold value using the calculated average value. The relationship between the average value and the threshold value may be determined according to a predetermined condition.

Of course, although the threshold value may be set in the setting unit 320 itself of each detection vehicle, the threshold value set by the information providing server may be received and set. For example, it is preferable to calculate the threshold value using the distance values collected by the information providing server, and receive and set the threshold value calculated by the detection vehicle from the information providing server. A process of setting a threshold in the information providing server will be described with reference to FIG. 5.

The detector 330 is configured to detect a roadside parkable space by using the threshold value set by the setting unit 320 and the distance values calculated using the ultrasonic sensor 350 while the detection vehicle moves. When the value is greater than or equal to the threshold value, it may be determined that there is no specific substance, for example, a vehicle, in the parking space of the location, and the vehicle is parked by a predetermined distance, for example, by a predetermined length so that the vehicle can park. It is determined whether the distance value is greater than or equal to the threshold value, and when the distance value is greater than or equal to the threshold value, the corresponding space is detected as a parking space at the roadside.

That is, the detector 330 calculates the distance value by using the ultrasonic sensor while the detection vehicle 210 moves with respect to five roadside parking spaces as shown in the example shown in FIG. 4, If all distance values over a certain length are above the threshold (in case of B), the area is detected as a parking space on the roadside, and for the remaining areas (A, C to E), all distance values over a certain length are thresholds. Since the above is not satisfied, the parking space is detected as impossible.

However, as an exceptional case, when the detection vehicle is moving and the distance value is less than the threshold value in consideration of the case where a person or a movable object is placed in the roadside parking space (in case of D) when calculating the distance value, the preset first length For example, when it is below a predetermined counting value, it is possible to detect the space as a parking space by determining that an arbitrary object has been placed for a while.

As described above, in the present invention, even a roadside parking space that can be parked by a movable person or object can be considered, thereby providing information about a lot of parking spaces to a user who requests parking space information.

In addition, when the space is detected as a parking space by the detector 330 in the present invention, the GPS information is positioned by using the GPS receiver 360 to provide information about the space, and a visual image is provided. In order to capture the space, the camera 370 may be used.

Here, the GPS receiver 360 is a means for acquiring location information about the region or location, and is not necessarily limited to the GPS receiver. In other words, any means capable of obtaining location information may replace the GPS receiver of the present invention.

When the detection unit 330 is detected as a parking space by the detector 330, the transfer unit 340 transmits the location information and the captured image information about the space to the information providing server.

Of course, the transmission unit 340 may also transmit the detection vehicle information, for example, detection vehicle ID, or may also transmit information on a sensor or a camera, a GPS receiver, etc. included in the detection vehicle, to the information providing server. It is preferable that the information is the minimum information that can provide information on the roadside parking space, and it is obvious that information related to the detection vehicle and the devices provided in the detection vehicle may be transmitted together.

Referring back to FIG. 2, the information providing server 220 receives information about a space available for parking on the roadside received from the detection vehicle 210 through a mobile communication network, for example, location information and image information, and receives the received information. It stores the information, and updates the information in real time, and when the roadside parking space information for a specific area is requested from the user terminal 230 through the wired and wireless Internet to search the available parking space in the area of the user terminal 230 )

The information providing server 220 may select and store the parking available information received from the detection vehicle 210, which may not be the actual parking available space detected by the detection vehicle, or the illegal parking surveillance camera is located. Since it may be an area, it is desirable to determine whether the received parking space is an actual parking space and store information on the same.

Of course, the user may determine whether the corresponding space is a parking space by providing the user terminal 230 with the map information and the image information on which the parking available location is displayed depending on the situation.

Such an information providing server will be described in more detail with reference to FIG. 5.

FIG. 5 illustrates a configuration of an embodiment of the information providing server shown in FIG. 2.

Referring to FIG. 5, the information providing server 220 includes a manager 510, a determiner 520, an information provider 530, and a database 540.

The database 540 is configured to store information for providing a service of the present invention, map information for interworking with a GIS, location information on an actual roadside parking space for each region, information about devices provided in a detection vehicle, and It may include information about the user.

Here, the database 540 may be configured in the information providing server but may be configured separately.

The management unit 510 manages information on devices, such as an ultrasonic sensor, a GPS receiver, and a camera, and information on devices to be added later, provided in detection vehicles selected by region, and provides a service of the present invention. Create / delete a user group and perform authentication on a user. User authentication can apply all the existing authentication methods.

Of course, it will be apparent to those skilled in the art that the information required for providing the service of the present invention can be managed.

The determination unit 520 is configured to determine whether the space determined to be parked by the detection vehicle is an actual parking space. When the location information on the roadside parking space is received from the detection vehicle, the determination unit 520 stores the received location information in the database 540. ), And determine whether the space is a real roadside parking space.

The information providing unit 530 displays the location of the available parking space on a map by interlocking with the GIS the space information available for roadside parking for a specific area requested from the user terminal, and provides a map displaying the available parking space to the user terminal. In addition, information necessary for providing the service of the present invention may be provided together.

In addition, although the image information may be provided together with the available parking space, the image information may be provided only when requested by the user.

Although not shown in FIG. 5, the information providing server may be provided with means for setting a threshold for determining a roadside parking space in the detection vehicle. That is, the distance values initially collected by the at least one detection vehicle assigned to the region may be received, and the threshold may be set using the received distance values. The same applies to the setting method. For example, after extracting only a range of distance values among the distance values collected by the detection vehicles, the threshold value may be set using the average value of the extracted distance values. Here, the threshold value may be a calculated average value or may be calculated by applying a weight to the average value or substituting a preset formula.

As described above, the roadside parking space information providing system according to the present invention detects the parking space available by the detection vehicle and compares the actual roadside parking space with the server to provide only the parking space to the user, thereby realizing accurate roadside parking space in real time. Can be provided quickly to the user.

In addition, because the detection vehicle is used, the service is available to all regions of the country, not limited to a specific region, and it is possible to reduce the installation cost of the system and to reduce the influence of the weather because it does not need to use the built-in sensor.

(S610).

Using the collected distance values, a threshold value for determining a parking space on the roadside is set (S620).

Here, the method of setting the threshold value may be set in the detection vehicle itself as described above, or may be set in an information providing server that receives distance values from a plurality of detection vehicles in a corresponding region. The detection is stored in the vehicle.

When the threshold is set, the detection vehicle calculates the distance value of the roadside parking space by using an ultrasonic sensor while moving the corresponding area to detect the space available for parking on the roadside (S630).

The calculated distance value is compared with the threshold value, and it is determined whether all distance values are greater than or equal to the threshold value for a predetermined predetermined distance or time (S640).

That is, the parking available space may be determined by determining whether all distance values are greater than or equal to a threshold value with respect to the preset length so that the vehicle can be parked.

As a result of the determination in step S640, when it is determined that all the distance values are greater than or equal to the threshold value for a predetermined length, the corresponding roadside space is detected as a parking space available (S650).

Furthermore, the detection of the parking space is not limited to all distance values exceeding a threshold value for a predetermined length, and considering the case where a person or a movable object is placed in the space, the vehicle can be parked for a predetermined length. Even if the distance value is less than the threshold value, the space can be determined as a parking space.

When the parking space is detected as described above, the location information of the detected parking space is located by using a GPS receiver and an image of the space is recorded by using a camera, and then the location information and the photographed image information are measured. It delivers to the information providing server that provides the service (S660, S670).
