Description

  The present invention relates to an overpassing prevention program for preventing overpassing a destination station in a transportation facility and a portable terminal equipped with the overpassing prevention program.

If you get on a train, get tired, or get drunk, you may accidentally fall asleep, fail to get off at the disembarking station, and get over.
In order to prevent such overpass, conventionally, the station code set for each station is transmitted from the base station installed at the station, and the above transmission is performed by the PHS portable terminal possessed by the passenger who is on the arriving train. A system has been proposed that receives a received station code and issues a warning when the station code matches the exit station code set by the passenger (see Patent Document 1).
Japanese Patent Laid-Open No. 11-41169

  However, in the conventional system, it is necessary to install a transmitter that constantly transmits the station code to the base station of the station, a station code setting switch, and the like, and the PHS portable terminal has a station code detector and code converter. There was a problem that it was not possible to realize it with existing devices alone.

  In order to solve the above problems, the present invention provides a current position of a user who possesses a mobile terminal using a mobile terminal that includes a transmission / reception unit, an input unit, a storage unit, an output unit, and a CPU and has a current position acquisition function Obtain information periodically, obtain the destination station list from the storage unit that stores the destination station list in advance, and sequentially obtain the location information for all the destination stations on the destination station list and compare with the current location information And determine whether it is near the target station, repeat until the target station is found, and if the target station is found, operate the output unit to notify the user that it is near the target station. When the notification stop operation is performed, the operation of the output unit is stopped.

Since the present invention is implemented by application software installed in a mobile terminal, there is an effect that a dedicated device is not necessary and can be realized only by an existing device.
In addition, users can use their mobile devices, such as mobile phones, as they are, and once they download the travel prevention program, they simply set the destination station and avoid transit charges without incurring communication charges. Can benefit from.

  A function of periodically acquiring current location information of a user who has a mobile terminal using a mobile terminal having a current location acquisition function, comprising a transmission / reception unit, an input unit, a storage unit, an output unit, and a CPU; The function of acquiring the destination station list from the storage unit storing the destination station list and the location information of all the destination stations on the destination station list are obtained sequentially, and compared with the current location information, whether it is near the destination station. A function to determine whether it repeats until the destination station is found, a function to operate the output unit to notify the user that it is near the destination station, and the user stops notification When the operation is performed, the overtime prevention program for causing the computer to realize the function of stopping the operation of the output unit is downloaded to the portable terminal and executed.

  FIG. 1 is a diagram showing a system configuration of the present invention. A system using, for example, a mobile phone as a mobile terminal includes a mobile phone 1 used by a user, a mobile phone network 2 operated by a mobile phone operator, and a server 3 which is equipment of an information service provider. This configuration itself is the same as the conventional mobile phone system. The server 3 is connected to the mobile phone network 2 via the Internet.

FIG. 2 is a block diagram of the mobile phone.
The cellular phone 1 generally includes a transmission / reception unit 11, an input unit 12, a storage unit 13, an output unit 14, and a CPU (Central Processing Unit) 15.
The transmission / reception unit 11 is a part that performs the communication function of the cellular phone 1, and the input unit 12 corresponds to various buttons for input such as dial buttons. The storage unit 13 is a so-called memory, and is a part that stores the overpass prevention program of the present invention, a destination station list including destination station information, and the like.

The output unit 14 constitutes means for notifying that a train or the like has approached the getting-off station, that is, near the target station of the present invention, and corresponds to a speaker, a vibrator, an incoming lamp, a display, and the like.
When notifying the user by sound, the speaker is sounded. When notifying by vibration, the vibrator is vibrated. When notifying by light, the incoming call lamp is blinked, and images and characters are displayed on the display.
The CPU 15 is a so-called computer part, and includes a current position information acquisition unit 16, a destination station list / target station location information acquisition unit 17 of the present invention, and an arithmetic / control unit 18 that performs arithmetic processing and controls the operation of each unit. Yes.

FIG. 3 is a flowchart showing the basic sequence of the present invention.
The overrun prevention program of the present invention causes the CPU 15 shown in FIG. 2 as a computer to realize the function for executing this basic sequence. This program is prepared by the information service provider shown in FIG. Provided as a site from the server 3.
Therefore, for example, the user selects from the cellular phone 1 of FIG. 1 using a menu or the like and connects to the server 3, downloads the overpass prevention program and stores it in the storage unit 13 of FIG. There is no need to download the program from the site if the manufacturer, etc., is standard on the shipment stage.

Next, the user sets the station name of one or a plurality of destination stations (alighting station, transfer station) from the setting screen of the overpass prevention program. If there is a station with the same name, the name of the station is specified by inputting the route name according to the instruction of the server 3.
The server 3 converts it into position information (longitude / latitude information) and returns it, and stores it in the storage unit 13 as a destination station list including the position information.
If a server for setting the station name can be prepared on the information service provider side, the user can set the station name via the Internet from a personal computer or the like instead of from the mobile phone 1.

The overpass prevention program installed in the mobile phone 1 operates according to the specifications of the mobile phone 1 so that it operates when the power is turned on or when the program is selected from the menu.
It is also possible to operate it attached to another application.

On the other hand, a certain type of mobile phone 1 has a function of acquiring the current position of the user who owns the mobile phone 1. Mainly, it uses a signal from GPS (Global Positioning Systems) or a base station.
The present invention uses such a current position acquisition function of a mobile terminal, for example, the mobile phone 1.

The flowchart of FIG. 3 will be described with reference to FIG.
When starting, as the first process, the current position information (longitude / latitude information) obtained by the function of the mobile phone 1 is periodically acquired from the mobile phone 1 by the current position information acquisition unit 16 (step S1). The term “regular” is, for example, about once every few seconds (1 to 5 seconds).
Next, the destination station list / target station position information acquisition unit 17 acquires the destination station list from the storage unit 13 of the mobile phone 1 that stores the destination station list in advance (step S2).

In step S3, a process of repeating the number of destination stations listed in the destination station list is started.
That is, the position information of the first destination station on the destination station list is acquired (step S4) and sent to the calculation / control unit 18 (step S5).
In step S5, the current position information previously acquired by the calculation / control unit 18 is compared with the target station position information, and it is determined whether or not it is near the target station.
If it is not near the destination station (N), the process returns to step S4 to obtain position information of the second destination station, and it is determined whether or not it is near the destination station in step S5. Returning to S4, the processing is repeated for all the target stations on the target station list until the vicinity of the target station is found.

When the vicinity of the destination station is found in step S5 (Y), the output unit 14 is operated to notify the user that the destination is near the destination station (step S7).
When the notified user performs a notification stop operation (step S8), the operation of the output unit 14 is stopped to stop the notification (step S9), and the process returns to the first process (step S1).
If the user does not perform a stop operation in step S8, notification is continued.

  Even if it is determined for all the destination stations in step S5, if the vicinity of the destination station is not found, it means that the destination station is not yet close. In step S6, the process of repeating the destination station list number of times is terminated. The process returns to the first process (step S1).

  In the above case, the vicinity of the destination station is an area in a circle drawn around the center of the destination station, and the radius of the circle is determined to be about 300 m to 500 m, for example.

FIG. 4 shows a display example for notifying the user.
In step S7, the output unit 14 is operated to notify the user that it is in the vicinity of the destination station. As an example of display on the display of the output unit 14, a destination map is shown in FIG. The characters around the station (in this example Shibuya) are flashed with light.
Such route map information may be transmitted from the server 3 of the information service provider together with the destination station position information and stored in the storage unit 13 of the mobile phone 1.
In addition to this, it may be possible to display "I will arrive at the destination station soon".
In addition, by driving the speaker of the output unit 14, the user can be notified of the arrival at the destination station by ringing the same or different ringing tone as that of the incoming call or by vibrating the vibrator. It is of course possible to notify by a plurality of means at the same time.

  Note that the notification stop operation in step S8 can be performed by selecting and operating the stop button on the display screen, or by pressing the power button in the same operation as the end of the call.

As described above, according to the present invention, there is no need for a dedicated device, and it is possible to prevent overriding only with an existing device.
In addition, once the user has downloaded the overpass prevention program to the mobile terminal, the user can receive the benefit of overpassing without setting a destination station and incurring a communication fee.

In addition, since the present invention does not have a land intuition (route intuition) on a route that the travel destination or the like does not know, it is forced that the destination station will pass, but there is also an effect of relieving the tension to some extent.
It is also very useful because it can be notified by sound, vibration, and light to those who cannot see the station signboard due to visual impairment or who cannot hear the announcement at the station due to hearing impairment.
In addition, since the information service provider is only provided with an overpass prevention program and destination station information from the site, no special equipment is required, it can be handled by existing facilities, and installation and maintenance costs are low. There are advantages.

FIG. 5 is a flowchart of the first embodiment of the present invention, and shows a specific example of step S5 in FIG. Therefore, only the previous and subsequent steps are displayed, and other steps are omitted.
Step S5 is a step of determining whether or not it is near the destination station. In the first embodiment, this is embodied in steps S11 and S12.

In step S11, the distance from the current position to the target station is calculated based on the current position information and the target station position information.
In step S12, it is determined whether the distance value is equal to or smaller than a predetermined value. This predetermined value is the same as the radius of the circle already described in the circle defining the vicinity of the destination station. Therefore, it is set to about 300 to 500 m, for example.
If this value is too small, the first vehicle will arrive at the destination station's platform without notification, and if it is too large, it will be notified that it is near the destination station even though it is far from the destination station. This should be determined in consideration of the length of the home and the length of the home.

  As described above, according to the first embodiment, the above-described effects can be obtained, and the distance from the current position to the destination station can be easily calculated based on the longitude / latitude information of the current position information. It is also easy to determine whether the value is less than or equal to the value.

FIG. 6 is a flowchart of the second embodiment of the present invention, in which steps S21 and 22 are added to the end of step S6 of the first embodiment shown in FIG.
As a result of repeated determination for all destination stations on the destination station list, if the distance from the current position to the destination station exceeds a predetermined value in all the destination stations (step S21), the distance for each destination station is temporarily set. The distance is calculated and the distance is the smallest, that is, the distance from the current position to the nearest destination station is selected, the processing is stopped for a predetermined time according to the distance, and after the predetermined time has passed, the step The process returns to the first process of S1.

In short, frequent acquisition of current location information places a load on the mobile phone, so if the distance from the current location to the target station is the shortest, the interval until the next acquisition of current location information is set. It is something that tries to be long.
Therefore, in the case of the sequence returning to step S1, it is preferable to insert steps such as steps S21 and 22 before the step S1 because the load on the mobile phone is reduced.

This acquisition interval is substantially the same as the predetermined time during which processing is stopped. The predetermined time is calculated by the following formula, for example.
Predetermined time (t) = (x−r) / v × a
x is the distance to the shortest destination station, r is the radius of the circle indicating the vicinity of the destination station, v is the maximum speed of the train, etc. a is an accuracy correction constant, and is used to absorb errors in the position acquisition accuracy of the mobile phone. It is 1.5-2.
For example, if r is 500 m, v is the Shinkansen speed of 300 km (about 83 m / s), and a is 2, then x = 3 km, t = 15 seconds, x = 5 km, t = 27 seconds, x = 10 km, t = about 1 Min, x = 50 km, t = about 5 min.
Therefore, for example, if the distance to the shortest destination station is up to 3km, the initial acquisition interval, 15 seconds for 3-5km, 30 seconds for 5-10km, 1 minute for 10-50km, 5 minutes for 50km or more will be stopped for a predetermined time. It ’s fine.

  As described above, according to the second embodiment, in addition to the effects of the first embodiment, the current position information acquisition interval can be changed according to the distance to the destination station having the shortest distance from the current position. If the distance is long, the processing can be stopped for a predetermined time, and the acquisition interval of the current position information can be lengthened to reduce the load on the mobile phone.

FIG. 7 is a flowchart of the third embodiment of the present invention. Steps S31 and S32 are added to the end of the flow in the case of the vicinity of the target station (Y) in step S5 of FIG. 3, and step S33 is further added to step S6. -35 is added.
If it is determined in step S5 that it is near the destination station for the first time (Y), there is no final notification station, so in step 31 it is not the final notification station (N), and in step S32, it is set as the final notification station, and the mobile phone 1 storage unit 13.
As described above, the output unit 14 is operated in step S7 to notify the user of arrival at the destination station. At this time, it goes without saying that the final notification station may be stored after changing the order and notifying. The point is to carry out both the memory of the final notification station and the notification to the user.

In step S5, when it is determined that the destination station is (Y) after the second time, it is checked in step S31 whether it is the same as the final notification station stored in the storage unit 13, and is the same as the final notification station. In the case of (Y), the process returns to the first process in step S1 without notifying the user.
If the flow does not follow this, after the notification is stopped in step S9 in FIG. 3, when the processes in steps S1 to S5 are performed, the same destination station may be hit and the user may be notified many times. However, multiple notifications can be prevented by using the above flow.
When it is different from the final notification station (N), the final notification station is set in place of the previous final notification station stored in step S 32, and is stored in the storage unit 13. In step S7, the user is notified of arrival at the destination station as described above, and the order of storage and notification is also as described above.

If it is determined in step S5 that it is not near the destination station (N), the processing is repeated for all the destination stations on the destination station list until the vicinity of the destination station is found as described in FIG. . If it is determined for all the destination stations that the destination station vicinity is not found, the process of repeating the destination station list number of times ends in step S6.
Next, in step S33, it is determined whether or not a final notification station exists. If not (N), the process returns to step S1.

If the final notification station exists (Y), in step S34, it is determined whether the current position acquired in step S1 is more than a certain distance from the final notification station. If not (N), the process returns to step S1.
If the current position is more than a certain distance from the final notification station (Y), the stored information on the final notification station is cleared (step S35). Then, the process returns to step S1.
Here, it is appropriate that the fixed distance is, for example, about twice the radius of the circle determined to be near the destination station. This is to prevent the notification from being repeated many times if it happens to move back and forth around the boundary of the same circle if it is of the same extent as the radius of the circle.

As described above, the steps S33 to S35 are provided when there is only one destination station in the destination station list, and once notified, it is set as the final notification station, and at the final notification station in step S31. If it is determined that there is, the process returns to step S1 and there is no timing to update the final notification station, so that it is prevented from being notified again.
When there are a plurality of destination stations in the destination station list and the destination stations are used every day, such processing is unnecessary.
Of course, steps S33 to S35 may be inserted between steps S1 and S2.

  As described above, according to the third embodiment, in addition to the above-described effects, the final notification station is stored, and if the vicinity of the destination station is found, it is checked whether it is the same as the stored final notification station. In such a case, since the process returns to the first process in step 1 without notifying the user, there is an effect that it is possible to prevent the same destination station from being hit and notifying the user multiple times.

Since the present invention is implemented by being mounted on a mobile terminal such as a mobile phone, the possibility of widespread use in the industry is great. However, it is considered that the application will be further expanded by linking with other route search systems.
For example, if the user uses the above system to set route information to the destination station (transfer destination information, directions to the destination after arrival at the destination station, etc.) in the overpass prevention program, the first destination station When approaching (transfer station), the above program notifies the user and also displays the information of the transfer destination (home number, departure time, destination, etc.) on the display of the mobile phone or by voice, and the user guides the transfer You will be able to transfer according to.
In addition, after arriving at the final destination station (getting off station), it is possible to go to the destination according to the directions displayed on the display.
In the above description, a mobile phone is exemplified as the mobile terminal. However, any mobile terminal having a current position acquisition function can be applied regardless of the name, such as a PHS mobile terminal. .
