The present invention relates to a system and method for preventing deviation of a hiking trail using a mobile communication terminal, and in particular, after installing a plurality of base stations around a hiking trail, measuring a position of a mobile communication terminal belonging to a corresponding region, and measuring the position and the built-in azimuth measuring means. The present invention relates to a system and method for preventing a trail departure from a mobile communication terminal in which a user knows a direction and a distance to return to when a mobile communication terminal deviates from a predetermined hiking trail.

Everyone agrees that a person usually needs a map and a compass to move to a new location. Thus, the compass is an essential device for maintaining a basic sense of direction. However, these days, mobile communication terminals are becoming a necessity of modern people, and thus, efforts have been actively made to add a compass function to display a user's current direction of travel and a direction to a destination.

In general, the GPS (Global Positioning System) function is used to obtain an accurate position of the mobile terminal user. This method was used to display the current location of a mobile phone user on a map through time information and location information received from a GPS satellite, or to display a path and direction information to a destination on a digital map.

However, the method of displaying the direction and location using GPS in the mobile phone is not only economically expensive due to the development of expensive satellites and GPS chips to utilize the GPS frequency, and also stores various map information and graphic information in the mobile phone. Since it is necessary to display at the same time, LCD (Liguid Crystal Display; LCD) display panel, which has a large memory and excellent graphics processing, must be used, which takes a long time and is expensive.

Accordingly, a mobile communication terminal having a compass function for improving productivity by providing a compass function indicating a direction of movement to a user by using a low-cost software method without using expensive GPS has come to appear.

As a mobile communication terminal having such a compass function, a physical compass is simply attached to the outside of the mobile communication terminal, and a method of measuring a direction by measuring an earth magnetic field using a geomagnetic sensor internally. In addition, after determining the location information of the mobile communication terminal by using the received power strength between the mobile communication terminal and a plurality of adjacent base stations, if the user of the mobile communication terminal moves, the direction of movement can be known as direction information. There is also a way.

The location and orientation information of the mobile communication terminal is used to provide unique information based on the mobility of the user, and the recently emerging service among wireless Internet services that can be provided by combining such personalization and mobility is based on location. Location Based Services: LBS (hereinafter referred to as LBS).

Such LBS service includes a service that informs the location of a specific mobile communication terminal, a service that displays its location on a map, and a service that informs driving information when driving a car. If the same information is provided, it is easy to use the service based on their location, but it is difficult to use in the case of mountain climbing where location and orientation are really important.

In particular, when the trail is complicated or when climbing deep mountains, it is easy to leave the trail, and once lost, there is a high risk of being distressed because it is difficult to return to the trail again. This way, if you get lost in the mountains, your life is in serious danger, and even if you are using a mobile communication terminal, even if you are not near the base station, it is difficult to make a call for rescue. In addition, even in the case of barely making a phone call, it is difficult to accurately describe its position, making the structure difficult.

Therefore, even if a mobile communication terminal capable of location-based services is provided, normal location-based services are difficult in places where there are few base stations and human resources, such as mountain climbing, and even if location-based services are available, it is difficult to find hiking trails through their location and orientation. .

As described above, the conventional mobile communication terminal has a function of knowing its location and direction of movement, and there is a method of knowing its location on a map, but it requires a large memory for embedding map data or receiving from outside. It is difficult to use location-based services smoothly in places where there is no accurate map data such as mountain climbing or in poor communication environments, such as mountain climbing, and it is possible to know its location and orientation through location-based services. Even if the trail is not able to determine how far in which direction, even if lost, the fact that the exact location or the exact location of the trail management office or rescue team had a problem that the structure is delayed.

In view of the above problems, the present invention is to install a base station around the trail, and to download the location information related to the hiking trails before climbing, by communicating with the base station around the trail to compare their location with the downloaded hiking trails A hiking trail using a mobile communication terminal that does not get lost in the mountains because it is easy to return to a hiking trail when a user leaves the trail using a mobile communication terminal that provides the user with a direction and distance to move to return to the mountain. It is an object of the present invention to provide a departure prevention system and method.

The present invention for achieving the above object, and a plurality of base stations disposed adjacent to the trail; Mobile communication with a compass function to check its location information by communicating with the base stations and to check the departure of the trail by comparing with the stored trail position information, and to provide the user with the direction and distance for returning when the trail is off Characterized in that it comprises a terminal.

The trail management office is connected to the base station, and the base stations provide the mobile communication terminal information that has escaped the trail more than a predetermined limit distance to the trail management office, and the mobile terminal information returned after the departure is also provided to the trail management office. Characterized in that.

According to another aspect of the present invention, there is provided a method for preventing a hiking trail departure using a mobile communication terminal having a compass function, the method comprising: storing hiking trail-related location information in the mobile communication terminal; Obtaining location information of the mobile communication terminal by communicating with a plurality of base stations adjacent to the hiking trail when entering the hiking trail; Confirming departure of the trail by comparing the obtained mobile communication terminal position information with previously stored trail-related position information; And providing direction information and distance information for re-entry to the user when the hiking trail deviates more than a predetermined distance as a result of the checking.

Hereinafter, with reference to the accompanying drawings, the present invention configured as described above will be described in detail.

1 is a conceptual view showing the configuration of an embodiment of the present invention. As shown in FIG. 1, when a plurality of base stations 30 are disposed around a hiking trail 20 located in a climbing region 10, the mobile communication terminal 50 has the hiking trail. When entering 20, the position of the mobile communication terminal 50 can be known by measuring the radio wave strength between the mobile communication terminal 50 and the adjacent base stations 30. The mobile communication terminal 50 is configured to have a physical compass on the outside or to use a built-in geomagnetic sensor to know the direction. Through this, the mobile communication terminal 50 can know the position and the direction information in the climbing area 10.

Before the mobile communication terminal 50 enters the hiking trails 20, the mobile communication terminal 50 must store the relevant location information about the hiking trails 20 and the climbing area 10 around the hiking trails 20 in advance, which is the hiking trails 20. The hiking trail management office 40 located at the entrance may be downloaded in a wired or wireless manner, and may be stored in advance in relation to the various hiking trails 20 internally, or may be downloaded through a wireless Internet access method. Alternatively, the downloaded file may be transmitted and stored to the mobile communication terminal 50 through various wired and wireless connection methods.

Therefore, the mobile communication terminal 50 can know the direction, the location of its own, and also know the location information of the hiking trails 20, if you go out of the hiking trails 20 to the hiking trails 20 again The direction and distance information for reentry can be calculated.

2 is a view illustrating an operation screen according to an embodiment of the present invention. As shown in FIG. 2, after downloading the hiking trail-related location information, communicating with a plurality of base stations 30 adjacent to the hiking trail, and identifying a position thereof, the hiking trail-related positions are stored. In comparison with the information, the direction and distance for entering the nearest hiking trail or the trailing trail where the trail is out of the trail can be determined. If the compass is external to the mobile communication terminal, the direction can be simply informed by the bearing information, and if the mobile communication terminal can grasp the bearing information by internally equipped with a geomagnetic sensor, the direction and the distance tracking screen showing the direction to move By continuously displaying the arrow and the distance as shown in (55), it is possible to allow the user to re-enter the hiking trail that has not escaped easily.

Even with the configuration and method described above, the hiker can easily return to the trail even if he has left the trail, and does not get lost in the mountains.

However, in the case of reinforcing the configuration a little more, the hiking trail management office can monitor the case of being isolated in the mountains due to unavoidable circumstances or leaving the trail by any other reason, so that the location of the subject can be quickly known when rescue work is required.

That is, since the base station 30 continuously communicates with the corresponding mobile communication terminal 50, the base station 30 can know the location information of the mobile communication terminal 50 and whether the hiking trail is deviated. If the trail is more than a distance away, the fact and the information and the location of the mobile communication terminal 50 can be notified to the trail management office can respond to it. If the mobile communication terminal 50 returns to the trail 20 again, the fact may also be notified to the trail management office. This allows the trail management office to find out how many people were leaving the trail, who left it when and when it was possible to call a hiker who did not return, or if he needed rescue assistance, You can move.

3 is a flowchart illustrating an operation of an embodiment of the present invention. As shown in the drawing, a user of a mobile communication terminal having a compass function stores location information related to a trail to be climbed by the user through various means.

Thereafter, when entering the trail, the trail tracking function is executed, which may be automatically executed, and selectively executed only when the user deems necessary.

When the trail tracking function is performed, the mobile communication terminal communicates with a plurality of base stations located adjacent to the trail to acquire its location information, and re-enters the track if it deviates more than a predetermined distance by comparing it with previously stored trail information. Providing direction and distance information for the clinic continuously until it re-enters the trail (adds an alarm or voice guidance if necessary).

When the reentry is complete, the user may be informed that the reentry is completed.

When using an embodiment of the present invention as described above, even if you use an unfamiliar hiking trail, there is no fear of getting lost in the mountains, and you have to leave the hiking trail due to unavoidable circumstances (injuries, fallouts, natural disasters, abductions, etc.). Even in this case, it can be recognized by the management office, facilitating rescue work, thus avoiding the worst.

As described above, the system and method for preventing departure of a hiking trail using the mobile terminal of the present invention may install a base station around the hiking trail, download the hiking trail-related location information before climbing, and communicate with a base station near the hiking trail. Comparing the downloaded hiking trails related location by providing the direction and distance to move to return and whether to leave the trail, induces a return when the user has left the trail without extensive map information or a large amount of communication Of course, if the information about this departure is monitored by the management office through the base station, it is possible to prevent various kinds of accidents occurring in the mountains or to cope quickly.
