It relates to a subway route guidance method in a mobile communication terminal to provide.

In recent years, due to heavy traffic, citizens' interest in the use of public transportation has become very high, and the majority of citizens use public transportation not only at the time of commuting and commuting but also as the main means of transportation in normal time. .

Among these public transportation methods, the utilization rate of the subway is increasing more than the public transportation on the ground, which is extremely heavy, and as the number of passengers increases, the number of subway lines continues to increase, and as the number of subway lines increases, the routes become more complicated. There is a trend.

Accordingly, in general, when a subway user wants to move to a specific destination, the subway user wants to move from the departure station at the current location by using the subway route map shown in the diary or the notebook or the route map provided by the subway history. Check the route to get to the destination station faster.

In this case, the subway user determines the route to the destination in consideration of the number of transfers depending on the number of stations or the transfer of each route to the destination in order to search for a faster route to the destination.

Such a decision method requires a user to move to the subway station provided with a route map when the subway user does not have a route guide map, and it is cumbersome to check and calculate the number of transit stations and transfer stations along each route. .

Furthermore, subway users cannot know exactly how long it will take to move the subway to each station section, so they choose a route with a small number of stations passing through it. There was a case where more time was spent.

In the case of the patent application No. 1997-036683 (name of the invention: a method for displaying a subway line in a pager), which has been proposed in order to reduce the inconvenience of the subway user, a specific subway selected by the user through the liquid crystal display of the pager In the case of patent application No. 1995-007573 (name of the invention: a system and method for calculating the shortest time required between subway and Somang stations), the shortest time is calculated by using information of a departure station and a destination station input by a user. In this way, since these methods display only a specific line on the liquid crystal display or calculate and provide the shortest time required according to the departure station and the destination station through a separate system, the subway user checks the route to the destination to which he / she wants to travel. There was a difficult problem to do.

Accordingly, the present invention has been proposed to solve the above-mentioned problems of the prior art, and searches various routes to a destination by using a starting point and a destination information input through a subway route guide menu of a user interface menu of a mobile communication terminal, By calculating the number of stations passing through each route and the time required for transfer, the distance, required time, and the shortest route to the destination are provided through the liquid crystal display of the terminal. It is an object of the present invention to provide a subway route guidance method in a mobile communication terminal to search for the shortest distance route.

The present invention for achieving the above object, the menu selection step of selecting a subway line guide menu in the user interface menu of the mobile communication terminal; A destination information input step of inputting a departure point and a destination information from the selected subway guide menu; A time calculation step of searching for all routes to the destination using the input destination information and calculating the number of stations passing through each route and the time required accordingly; And a route display step of aligning each searched route according to the calculated time required and displaying the route and time required for the route having the minimum required time on the liquid crystal display of the mobile communication terminal.

1 is an operation flowchart showing a subway line guidance method using a mobile communication terminal according to the present invention.

Hereinafter, the present invention will be described with reference to the accompanying drawings.

The mobile communication terminal according to the present invention searches for various routes to the destination with the source and destination information input by the user according to the operation algorithm, and the number of stations passing through each route based on whether or not to transfer, and accordingly It includes a control unit for calculating the required time to arrange each route in the order of MIN, MIN + 1, MIN + 2 according to the calculated time required to display the route and the required time of the route corresponding to the shortest distance on the liquid crystal display of the terminal .

In addition, the control unit displays a line including information of the station passing through the liquid crystal display unit, and moves, reduces or enlarges the image according to a user's key selection and provides it to the liquid crystal display unit.

The mobile communication terminal may include a memory unit in which information on each subway line in Seoul or a region, information on a time required between each station, and a time required for a transfer section is stored.

The required time is calculated based on the number of stations passing through each searched route and the movement time between stations, and is calculated by adding the transit time required for the transfer depending on whether the transit is made.

The hardware technical configuration of the control unit, the liquid crystal display unit, and the memory unit is a well-known technology and is not shown.

The subway line guidance method in the mobile communication terminal made as described above comprises: a menu selection step of selecting a subway line guide menu from a user interface menu of the mobile communication terminal; A destination information input step of inputting a departure point and a destination information from the selected subway guide menu; A time calculation step of searching for all routes to the destination using the input destination information and calculating the number of stations passing through each route and the time required accordingly; And a route display step of aligning each searched route according to the calculated time required and displaying the route and time required for the route having the minimum required time on the liquid crystal display of the mobile communication terminal.

The present invention thus made will be described in detail with reference to the flowchart of FIG. 1.

The mobile terminal user selects a subway route guide menu among user menus of the terminal and selects a corresponding region (S1).

Select the starting point menu from the subway route guide menu of the selected specific area, and enter the subway line of the starting point you want to use directly with the numeric keys on the terminal keypad or select it through the menu, and all stations of the entered subway line When displayed on the liquid crystal display together with the number, the starting station is selected and input using the direction keys or the corresponding numeric keys (S2).

After inputting the starting point information as described above, the destination menu is selected, and the destination station is searched for and selected from the information of each station displayed on the liquid crystal display (S3).

When the starting point and the destination information is input through this process, the controller of the terminal searches for the subway line passing through the input destination station (S4) and checks whether there is a line matching the subway line of the starting point among the searched subway lines. Determine (S5).

If the result of the determination is matched, the number of stations and the time required to pass through the path of the matching subway line is calculated (S6), and another route including the route to be transferred is searched and the station passed through each route. The required time including the number of transfers and the transfer time is calculated (S7).

According to the calculated time required, each searched route is sorted in the order of MIN, MIN + 1, MIN + 2 (S8), and the route of the route corresponding to the shortest distance among the sorted routes together with the time information on the liquid crystal of the terminal. It displays on a display part (S9).

On the other hand, if the determination does not match, all routes to the destination station including the transit station are searched, and the required time including the number of transit stations and transit time for each route found is calculated (S10).

According to the calculated time required, each searched route is sorted in the order of MIN, MIN + 1, MIN + 2 (S8), and the route of the route corresponding to the shortest distance among the sorted routes together with the time information on the liquid crystal of the terminal. It displays on a display part (S9).

In addition to the shortest distance in accordance with the user's request, the route of the searched route is displayed together with the required time information calculated on the liquid crystal display of the terminal.

For example, if a terminal user starts from Bangbae Station of Subway Line 2 and moves to Dongdaemun Stadium Station, which is a transit station of Subway Lines 2, 4, and 5, the user selects a subway line guide of Seoul from the user menu of the terminal.

From the starting point menu of the selected subway route guide, enter the subway line number 2, which is to be used at the starting point, and select the Bangbae station as the starting station, and then select and enter the Dongdaemun Stadium station from the destination menu.

When the starting point and the destination information is input in this way, the subway line of the Dongdaemun sports ground station as a destination is checked to determine whether or not it matches the subway line of the input starting point.

As the result of the determination is consistent, the number of stations that pass through Line 2 without first transfer is calculated. If the number of stations is 20 and the time between each section is 2 minutes, the time required is 40 minutes. Is calculated.

Thereafter, another route to the destination including the transit station is searched to calculate the time required for each route. If the transit line 4 is based on the Sadang station, the number of transit stations is 12 and the transit is made once.

If the travel time between each section is 2 minutes and the travel time is 5 minutes according to the transfer distance, the transfer route from Sadang Station to Line 4 is calculated as 29 minutes plus 24 minutes between stations and 5 minutes.

As such, the shortest distance is 1 at the Sadang Station because the route that transfers once at Sadang Station is the fastest among the calculated time periods for each route including each transfer path. It is searched by the transfer route.

According to the search result, the liquid crystal display of the user terminal displays the route of the route once transferred from Sadang Station, which is the shortest distance route.

The user checks the route of the shortest distance while moving the displayed route by using the side key or the direction key of the terminal or by enlarging or reducing the image by using the zoom in and zoom out function keys.

As described above, the present invention provides a subway line information of a route having a distance, a required time, and a minimum required time to a destination through a user interface menu of a mobile communication terminal, thereby allowing a terminal user to travel to the destination more quickly and conveniently. Provides the effect of identifying time and shortest route.
