Device and method for recognizing going out/returning of vehicle on smart home service

The present invention relates to a device and method for recognizing going out/home of a moving object in a smart home service, and more particularly, when providing an IoT smart home service, to control the IoT device according to going out/returning, It relates to a device and method for recognizing going out/home of a moving object in a smart home service for recognizing information about

Among IoT (Internet of Things, hereinafter referred to as "IoT") services, there is a user scenario in which various home appliances are controlled by recognizing a user's outing and returning home. In order to provide such a user scenario, a technology for recognizing a user's going out/homecoming is required.

To this end, as for the conventional out/home recognition method, 10-2016-0019644 (IoT smart mat for home care service provision) has been applied.

As described above, among the conventional methods for recognizing going out/home of a moving object, the IoT smart mat for providing home care service is intuitively installed at the entrance of each home, and the user recognizes it by accessing the mat when going out or returning home. However, there is a disadvantage in that you need to purchase a separate smart mat to provide these functions.

In addition, the parking lot vehicle access management system, which is another conventional outing/home recognition method, is a method of recognizing a user's going out or returning home by recognizing the number of a vehicle entering or leaving the parking lot.

However, the conventional parking lot vehicle access management system has a disadvantage that a service is available only in a building in which the corresponding facility is provided, and communication with the smart home device must be possible even if the corresponding facility is present.

In addition, the motion radius control apparatus and method of a moving object, which are another conventional out/home recognition method, can create a virtual fence using GPS location information and detect whether the location of the monitoring target is outside the area.

However, this technology relies solely on GPS location information to compensate for errors in GPS location information that change in real time, and it doesn't mention how to correct the error in areas where diffuse reflection of radio waves is expected, such as in cities.

The present invention has been devised to solve the problems of the prior art, and an object of the present invention is to establish a location information-based area, and to improve the smart home service by recognizing going out or going home in the user's location and moving direction. An object is to provide a device and method for recognizing going out/home of a moving object in a service.

Here, it is preferable that the boundary area setting unit sets the boundary area by adding a boundary line (TL) boundary line outside or inside the boundary line.

The entry/exit determination unit may determine that the state of the moving object is changed only when the corresponding area is maintained for a preset time after the position of the moving object is changed based on the boundary line.

In addition, the access determination unit, the location information provided from the moving object may include latitude information, longitude information, and direction and speed information of the vehicle.

In addition, the access determining unit compares the shape and direction of the road included in the map data with the moving direction of the moving object and, when confirming that the shape and direction of the road on the map do not match, determines the location information of the moving object to determine the access location can be excluded from, and the shape and direction of the road included in the map data and the direction of movement of the moving object are compared on the basis of the road, driving method information, or round-trip lane information on the map data to match the shape and direction of the road on the map. In this case, it is determined that the position information of the moving object is provided linearly.

On the other hand, the moving object, as a vehicle controller, provides direction information of the moving object provided through a vehicle steering device together with location information collected through GPS, and the access determining unit includes direction information and location information provided from the moving object. The received location information is excluded from the entry/exit location determination target by determining whether they match.

Here, the moving object provides direction information of the moving object collected through sensors sensing the moving direction of the moving object together with location information obtained through GPS.

Preferably, the access determination unit 120 determines whether the position of the moving object provided from the moving object is changed based on the boundary line TL.

According to an embodiment of the present invention, in order to recognize a moving object going out or returning home, by setting a boundary line (TL) using location information using GPS, without installing a physical device in the boundary area, installation is easy. Not only is it easy, but there is an effect that it is easy to move the installation area.

As shown in FIG. 2A , the boundary area setting unit 110 employed in the embodiment of the present invention adds an inner threshold boundary line T1 or an outer threshold boundary line T2 of the boundary line TL to the boundary area Ta ) is desirable to set.

Accordingly, the entry/exit determination unit 120 determines that the state of the movable body 200 is changed only when the corresponding area is maintained for a preset time after the position of the movable body 200 is changed based on the boundary line TL.

For example, according to an embodiment of the present invention, as shown in FIG. 2A , in a state in which the boundary area Ta is set with respect to the boundary line TL as a reference, the movable body (Ta1) located inside the boundary line TL (Ta1). 200) moves outside to go out.

In this case, there is a problem that the moving object may misrecognize going out/home depending on the vehicle moving trajectory.

On the other hand, according to the access determination unit 110 employed in an embodiment of the present invention, the criterion for judging going out, going home, going out is not the boundary line TL, but the boundary area Ta, and the location of the vehicle is Since it is determined that the moving object 200 goes out/returns only when it is maintained for more than a preset time after being changed, as shown in FIG. 2A , even if location information such as L0 to L6 is provided from the moving object 200, as shown in FIG. 2B Similarly, it is determined that the moving object 200 is going out through the information after the location information L6 of the moving object 200 .

Therefore, according to the access determination unit 110 employed in an embodiment of the present invention, even if an error occurs in the location information provided from the moving object 200 or the actual moving object 200 changes direction, the correct moving object goes out/returns. It has the effect of determining whether or not

According to another embodiment of the present invention, the entry/exit determination unit 120 may use direction and speed information in addition to location information including latitude information and longitude information to determine whether the moving object 200 goes out or returns. . To this end, the moving object 200 additionally provides direction and speed information of the moving object 200 together with location information including latitude and longitude information using GPS.

That is, as shown in FIG. 4 , when direction and speed information are provided along with the location information of the moving object 200 , the access determination unit 120 extracts the linearity of the road from the map data, and determines the direction in which the road extends. The moving direction of the vehicle can be corrected using can be excluded.

Therefore, according to another embodiment of the present invention, there is an advantage that stable and accurate recognition is possible by eliminating errors that may occur when determining whether the moving object 200 goes out or goes home.
