  Portable electronic devices that generate an alarm when approaching an alighting station are known.

  In Patent Document 1, the position of the getting-off station is specified using a database storing the position of the station and the name of the station, the current position is detected using a GPS (Global Positioning System) device, and the position of the getting-off station is determined. A portable terminal that compares the current position and detects that it is approaching the disembarking station is described. This mobile terminal generates an alarm when the current position approaches the disembarking station.

  Patent Document 2 describes a position information management system that includes a mobile terminal and a server that determines whether or not the mobile terminal has approached the getting-off station.

  In this position information management system, when the mobile terminal receives the getting-off station information regarding the getting-off station, the mobile terminal acquires the position information indicating the current position of the mobile terminal, and then transmits the getting-off station information and the position information to the server.

  When the server receives the getting-off station information and the position information, the server calculates the arrival time at the getting-off station based on the getting-off station information, the position information, and the train schedule information in the server, and transmits the arrival time to the portable terminal. .

  When the arrival time notified from the server is reached, the mobile terminal acquires the position information again and transmits the position information to the server.

  When receiving the position information, the server determines whether the mobile terminal is in a specific area including the getting-off station.

  When the mobile terminal is present in the specific area, the server transmits information for displaying arrival at the getting-off station to the terminal device.

  Embodiments of the present invention will be described below with reference to the drawings.

(First embodiment)
FIG. 1 is a block diagram showing a communication system including a portable electronic device according to the first embodiment of the present invention.

  In FIG. 1, a mobile phone 10 can communicate with a server 20 and a GPS satellite 30 via a network 40 such as the Internet. Note that the mobile phone 10 may communicate with the GPS satellite 30 without going through the network 40.

  Server 20 can generally be referred to as a management device.

  The server 20 stores at least information on the position of the station for each station name, and stores information on the operation speed of the vehicle traveling on the route for each route name.

  FIG. 2 is an explanatory diagram showing an example of information stored in the server 20.

  In FIG. 2, the server 20 stores a table 20A and a table 20B.

  In the table 20A, for each station, the station name 20A1, the station position information 20A2, the route name 20A3, and the route map 20A4 are stored in association with each other. The station position information 20A2 represents, for example, the latitude and longitude of the station. The route name 20A3 represents the name of a route entering the station. The route map 20A4 represents a route map specified by the route name 20A3.

  In the table 20B, for each route, a route name 20B1 and operation speed information 20B2 of a vehicle traveling on the route are stored in association with each other. The operation speed information 20B2 represents, for example, the maximum operation speed of a train that operates on a route.

  When the server 20 receives a request for route information from the mobile phone 10, the server 20 provides the route information to the mobile phone 10. The route information is a plurality of pieces of information stored in the server 20, for example, a station name, station position information, a route name, a route map, and operation speed information.

  Returning to FIG. 1, the GPS satellite 30 transmits information for detecting the current position.

  The mobile phone 10 can generally be called a portable electronic device.

  The cellular phone 10 requests necessary route information from the server 20 in accordance with a user operation. The mobile phone 10 displays the route information provided from the server 20 in response to the request.

  Further, the mobile phone 10 receives the information transmitted by the GPS satellite 30 according to, for example, a user operation. The mobile phone 10 detects the current position (latitude and longitude) based on information from the GPS satellite 30.

  The mobile phone 10 calculates the travel time required for the mobile phone 10 to move from the current position to the disembarking station based on the information acquired from the server 20 and the GPS satellite 30.

  The mobile phone 10 calculates the next timing for receiving information from the GPS satellite 30 based on the calculated travel time.

  The mobile phone 10 acquires information from the GPS satellite 30 at the calculated timing. The mobile phone 10 detects the latest current position based on the acquired information. Using the latest current location, the mobile phone 10 again calculates the travel time required for the mobile phone 10 to move from the current location to the disembarking station. For this reason, the mobile phone 10 corrects the travel time according to the actual vehicle operation status.

  The mobile phone 10 repeats the travel time and timing calculation processing until the mobile phone 10 enters the area around the disembarking station.

  When the mobile phone 10 enters the area around the disembarking station, it issues an alarm.

  FIG. 3 is a block diagram showing an example of the mobile phone 10.

  In FIG. 3, a mobile phone 10 includes an input unit 10a, a route information acquisition unit 10b, a position detection unit 10c, a calculation unit 10d, an alarm unit 10e, a control unit 10f, a memory 10g, and a display unit 10h. Display control unit 10i.

  Input unit 10a can be generally referred to as accepting means.

  The input unit 10a is, for example, an operation key or a touch panel. The input unit 10a accepts at least the name of the disembarking station. For example, the input unit 10a receives at least an alarm control instruction, a name of a disembarking station, and a route name. In this embodiment, the input part 10a receives the name and route name of alighting station after receiving an alarm control instruction.

  Route information acquisition unit 10b can be generally referred to as acquisition means.

  The route information acquisition unit 10 b can communicate with the server 20. When the input unit 10a receives the name of the getting-off station, the route information acquiring unit 10b acquires the position information 20A2 of the getting-off station and the operation speed information 20B2 on the route from the server 20. For example, when the input unit 10a receives the name and route name of the disembarking station, the route information acquisition unit 10b uses the name and route name of the disembarking station and uses the location information 20A2 of the disembarking station and the route from the server 20. The operation speed information 20B2 on the route indicated by the name is acquired.

  Position detection unit 10c can be generally referred to as detection means.

  The position detection unit 10c detects the current position at a designated timing. For example, the position detection unit 10c detects the current position when the input unit 10a receives an alarm control instruction. For example, when the input unit 10a receives an alarm control instruction, the position detection unit 10c receives information from the GPS satellite 30 and detects the current position (latitude and longitude) based on the information.

  Calculation unit 10d can be generally referred to as calculation means.

  Based on the current position detected by the position detection unit 10c, the position information 20A2 and the traveling speed information 20B2 of the getting-off station acquired by the route information acquisition unit 10b, the calculation unit 10d travels from the current position to the getting-off station. Calculate

  For example, the calculation unit 10d first calculates a linear distance between the current position and the getting-off station using the current position and the getting-off station position information 20A2. Subsequently, the calculation unit 10d divides the linear distance by the operation speed indicated by the operation speed information 20B2, and calculates the travel time from the current position to the disembarking station.

  Alarm unit 10e can be generally referred to as alarm means.

  Alarm unit 10e includes an alarm sound output unit 10e1 and a vibrator 10e2.

  Control unit 10f can be generally referred to as control means.

  When the calculation unit 10d calculates the travel time, the control unit 10f compares the travel time with a predetermined determination time (predetermined determination time).

  When the movement time is equal to or shorter than the determination time, the control unit 10f generates an alarm from the alarm unit 10e.

  On the other hand, when the travel time is longer than the determination time, the control unit 10f calculates a detection timing according to the travel time.

  For example, when the travel time is longer than the determination time, the control unit 10f calculates the detection timing based on the remaining time obtained by subtracting a predetermined adjustment time (predetermined adjustment time) from the travel time.

  As an example, the control unit 10f measures the current time, and calculates the time obtained by adding the remaining time to the current time as the detection timing time.

  The control unit 10f causes the position detection unit 10c to re-detect the current position at a detection timing corresponding to the movement time. Subsequently, the control unit 10f calculates a travel time to the calculation unit 10d based on the re-detected current position, the information on the position of the getting-off station acquired by the route information acquisition unit 10b, and the information on the operation speed. Let

  In the present embodiment, the control unit 10f counts the current time, and stores determination time information indicating the determination time and adjustment time information indicating the adjustment time.

  Display unit 10h can generally be referred to as display means. The display unit 10h displays various screens.

  Display control unit 10i can be generally referred to as a display control unit. The display control unit 10i controls the screen displayed on the display unit 10h.

  Next, the operation will be described.

  FIG. 4 is a flowchart for explaining the operation of the mobile phone 10. FIG. 5 is a flowchart for explaining an example of a display screen when accepting a name of a disembarking station and a route name.

  First, in order to start alarm setting, the user operates the input unit 10a to input an alarm control instruction. The input unit 10a receives an alarm control instruction input from the user (step 401).

  When the input unit 10a receives an alarm control instruction, the position detection unit 10c receives information from the GPS satellite 30 and detects the current position (latitude and longitude) based on the information (step 402).

  Further, when the input unit 10a receives an alarm control instruction, the display control unit 10i displays the getting-off station input screen on the display unit 10h. FIG. 5 shows an example of the getting-off station input screen 5a.

  The user operates the input unit 10a, and from the disembarking station input screen 5a, "1. Search nearest station from current location", "2. Select from past disembarking station", "3. Manual input" Either one is selected (step 403).

  When “1” is selected in step 403, the route information acquisition unit 10b accesses the server 20, and based on the current position detected by the position detection unit 10c, the names of stations around the current position and the station A route passing through is searched (step 404). The display control unit 10i displays the search results of the route information acquisition unit 10b on the display unit 10h in order from the current position. FIG. 5 shows an example of the nearest station screen (station list) 5b displayed in step 404.

  Subsequently, the user operates the input unit 10a to select a pair of the nearest station and route from the nearest station screen (station list) 5b (step 405).

  When the nearest station and route are selected, the route information acquisition unit 10b accesses the server 20 and searches for a plurality of stations before and after the selected route with the selected station as the center. The display control unit 10i displays an exit station candidate screen in which the search results of the route information acquisition unit 10b are lined up and down with the selected station sandwiched therebetween on the display unit 10h (step 406). FIG. 5 shows an example of the getting-off station candidate screen 5c displayed in step 406.

  The user operates the input unit 10a to scroll the station name displayed on the exit station candidate screen 5c, select the exit station and the route (step 407), the exit station (name of the exit station) and the route ( The route name is determined (step 408).

  When “2” is selected in step 403, the display control unit 10i lists “disembarking station + route” selected in the past from the memory 10g. The display control unit 10i displays a screen representing the listed “getting off station + route” on the display unit 10h (step 409). FIG. 5 shows an example of a past disembarking station screen 5d displayed in step 409.

  Subsequently, the user operates the input unit 10a to scroll the station name displayed on the past disembarking station screen 5d, select “disembarking station + route” (step 410), and disembarking station (disembarking station) And the route (route name) are determined (step 408).

  When “3” is selected in step 403, the display control unit 10i displays a manual input screen on the display unit 10h. FIG. 5 shows an example of the manual input screen 5e.

  Subsequently, the user operates the input unit 10a to input “discard station name + route name” on the manual input screen 5e (step 411), and enter the disembarkation station (discard station name) and route (route name). Determine (step 408).

  When the getting-off station (name of the getting-off station) and the route (route name) are determined, the display control unit 10i displays an alarm screen on the display unit 10h (step 412). FIG. 5 shows an example of the alarm screen 5f.

  Subsequently, the user operates the input unit 10a to select either “1. vibration” or “2. alarm”.

  This completes the setting by the user (step 413).

  When the setting by the user is completed, the route information acquisition unit 10b accesses the server 20 and uses the name and route name of the getting-off station determined in step 408, and the location information 20A2 of the getting-off station and the operation on the route. Speed information 20B2 is acquired (step 414).

  Subsequently, the calculation unit 10d calculates a linear distance (D) between the current position detected in Step 402 and the position of the disembarking station represented by the disembarking station position information 20A2 (Step 415).

  Subsequently, the calculation unit 10d calculates the shortest arrival time (T) (= D / S) using the linear distance (D) and the maximum operation speed (S) represented by the operation speed information 20B2. (Step 416). Note that the shortest arrival time (T) can generally be referred to as the travel time from the current position to the disembarking station.

  The calculation unit 10d calculates the shortest arrival time (T) using the linear distance (D) and the maximum operation speed (S). For this reason, the shortest arrival time (T) is different from the travel time according to the actual operation status. However, it is possible that the shortest arrival time (T) does not fall below the actual travel time.

  When the shortest arrival time (T) is longer than 2 minutes (determination time), the control unit 10f again, when the time obtained by subtracting 1 minute (adjustment time) from the shortest arrival time (T) has elapsed, The position detection unit 10c is made to detect the current position, and the calculation unit 10d is made to calculate the shortest arrival time (T) again.

  On the other hand, when the shortest arrival time (T) is 2 minutes (determination time) or less, the control unit 10f activates the alarm unit 10e.

  The determination time is not limited to 2 minutes and can be changed as appropriate. Further, the adjustment time is not limited to 1 minute and can be changed as appropriate.

  Specifically, the control unit 10f first determines whether or not the shortest arrival time (T) is longer than 2 minutes (step 417).

  When the shortest arrival time (T) is longer than 2 minutes, the control unit 10f acquires the information from the GPS satellite 30 next time, the time one minute before the time obtained by adding the shortest arrival time (T) to the current time. The time (after dT time) is set (step 418).

  The control unit 10f operates the position detection unit 10c when dT time has elapsed from the current time. The position detector 10c receives information from the GPS satellite 30 and detects the current position based on the information (step 419).

  The mobile phone 10 repeats Steps 415 to 419 until the shortest arrival time (T) calculated based on the current position acquired in Step 419 becomes 2 minutes or less. By this operation, the shortest arrival time (T) can be brought close to the actual operation status.

  In step 417, when the shortest arrival time (T) is 2 minutes or less, the control unit 10f generates an alarm from the alarm unit 10e at that time. At this time, the control unit 10f operates the alarm unit (the alarm sound output unit 10e1 or the vibrator 10e2) set in step 412 (step 420).

  The simulation is shown below.

The maximum operation speed (S) is 100 km / h, and the distance (D) between the current position and the getting-off station is 50 km.
-At the start of setting Shortest arrival time (T) = 50/100 = 0.5h = 30 minutes T> 2 minutes, so dT = 30-1 = 29 minutes The next time to perform position detection using GPS is 29 minutes later It becomes.
-29 minutes later The current position is detected using GPS.

Distance between current position and getting off station (D): 15km
Shortest arrival time from this point (T) = 15/100 = 0.15h = 9 minutes T> 2 minutes, so dT = 9-1 = 8 minutes The next time to perform position detection using GPS is 8 minutes later It becomes.
・ After 8 minutes, the current position is detected using GPS.

Distance between current position and getting off station (D): 5km
Shortest arrival time from this point (T) = 5/100 = 0.05h = 3 minutes T> 2 minutes, so dT = 3-1 = 2 minutes The next time to perform position detection using GPS is 2 minutes later It becomes.
・ After 2 minutes, the current position is detected using GPS.

Distance between current position and getting off station (D): 3km
Shortest arrival time from this point (T) = 3/100 = 0.03h = 1.8 minutes Since T <2 minutes, the alarm is activated.

  Next, the effect of this embodiment will be described.

  According to the present embodiment, the position detection unit 10c detects the current position at a designated timing. Based on the current position detected by the position detection unit 10c, the information on the position of the disembarking station acquired by the route information acquisition unit 10b, and the information on the operation speed, the calculation unit 10d travels from the current position to the disembarking station. Calculate When the calculation unit 10d calculates the travel time, the control unit 10f compares the travel time with the determination time. When the movement time is equal to or shorter than the determination time, the control unit 10f generates an alarm from the alarm unit 10e.

  The position detection unit 10c operates at a designated timing (for example, a predetermined time interval or a timing designated by a user operation). For this reason, it becomes possible to reduce electric power consumption compared with the case where the position detection part 10c always operate | moves.

  Further, when the movement time is equal to or shorter than the determination time, the control unit 10f generates an alarm from the alarm unit 10e. For this reason, the route information acquisition unit 10b does not need to communicate with the server 20 when the travel time is equal to or shorter than the determination time. For this reason, it is possible to prevent an alarm from being generated due to a communication failure between the mobile phone 10 and the server 20 when the travel time is equal to or shorter than the determination time.

  Further, according to the present embodiment, when the movement time is longer than the determination time, the control unit 10f causes the position detection unit 10c to detect the current position at a detection timing corresponding to the movement time, and the detected current Based on the information on the position and the position of the disembarking station and the information on the operation speed, the calculation unit 10d is caused to calculate the travel time. When the calculation unit 10d calculates the travel time, the control unit 10f compares the calculated travel time with the determination time.

  For this reason, based on the current position detected by the position detection unit 10c, it is possible to calculate a travel time that is as close as possible to the actual operation schedule.

  Further, when the movement time is longer than the determination time, the control unit 10f operates the position detection unit 10c at the detection timing corresponding to the movement time, and thus adjusts the detection timing of the position detection unit 10c according to the movement time. It becomes possible to do.

  Therefore, it is possible to operate the position detection unit 10c only when position information is necessary, and it is possible to suppress power consumption caused by unnecessary operation of the position detection unit 10c.

  In the present embodiment, the control unit 10f delays the operation timing of the position detection unit 10c as the movement time is longer.

  In this case, it is possible to prevent the position detection unit 10c from operating frequently when the mobile phone 10 is located far from the disembarking station, that is, when it is not necessary to frequently check the position of the mobile phone 10.

  In the present embodiment, the route information acquisition unit 10b does not need to communicate with the server 20 after the calculation unit 10d calculates the travel time. For this reason, an alarm is not generated due to a communication failure between the mobile phone 10 and the server 20 after the calculation unit 10d calculates the travel time.

  As described above, according to the present embodiment, even when the user is sleeping on a train, for example, if a simple alarm is set, the user can avoid sleeping and passing through the destination.

  In the present embodiment, the control unit 10f calculates the detection timing based on the remaining time obtained by subtracting the adjustment time from the travel time. In this case, an alarm can be generated with a high probability before the vehicle arrives at the disembarking station.

  In the present embodiment, the maximum operation speed of the vehicle is used as the operation speed information. In this case as well, an alarm can be generated with high probability before the vehicle arrives at the disembarking station.

Furthermore, the input unit 10aA receives the determination time information and stores the determination time information in the control unit 10f. Further, the input unit 10aA receives the adjustment time information and stores the adjustment time information in the control unit 10f.

  If the determination time represented by the determination time information is Y minutes and the determination time represented by the adjustment time information is X minutes, in step 417, it is determined whether or not the movement time is longer than Y minutes.

  The dT calculated in step 418 is dT = T−X / 60.

  According to the present embodiment, the input unit 10aA receives determination time information. The control unit 10f uses the determination time represented by the determination time information as the predetermined determination time.

Hereinafter, the third embodiment will be described focusing on differences from the first embodiment.

  Compared to the first embodiment (mobile phone 10), in the third embodiment (mobile phone 10B), a management unit 10j is provided, and a route information acquisition unit 10bB is used instead of the route information acquisition unit 10b. ing.

The operation speed information 20B2 on the route indicated by the route name is acquired.

  According to the present embodiment, the mobile phone 10B does not need to communicate with the server 20, and the processing of the mobile phone 10B can be simplified.

(Fourth embodiment)
FIG. 8 is a block diagram showing a mobile phone 10C according to the fourth embodiment of the present invention. In FIG. 8, the same components as those shown in FIG. Hereinafter, the fourth embodiment will be described focusing on differences from the first embodiment.

  Compared to the first embodiment (mobile phone 10), in the fourth embodiment (mobile phone 10C), the memory 10g, the display unit 10h, and the display control unit 10i are omitted.

  According to the present embodiment, the mobile phone 10C includes the input unit 10a, the route information acquisition unit 10b, the position detection unit 10c, the calculation unit 10d, the alarm unit 10e, and the control unit 10f. As described in the embodiment, it is possible to operate the position detection unit 10c only when position information is necessary, and it is possible to suppress power consumption caused by unnecessary operation of the position detection unit 10c. .

  Further, after the calculation unit 10d calculates the travel time, the route information acquisition unit 10b does not need to communicate with the server 20. For this reason, an alarm is not generated due to a communication failure between the mobile phone 10 and the server 20 after the calculation unit 10d calculates the travel time.

  Therefore, as in the above embodiments, it is possible to generate an alarm with a high probability when approaching the getting-off station.

  In each embodiment described above, the illustrated configuration is merely an example, and the present invention is not limited to the configuration.

  For example, the input unit 10aA shown in the second embodiment may be used instead of the input unit 10a of the third or fourth embodiment.

  Further, the operation speed information 20B2 stored in the server 20 or the management unit 10j may represent the average operation speed (A) instead of the maximum operation speed (S). In this case, the calculation unit 10d can calculate a movement time that is close to the actual movement time. For this reason, it becomes possible to manage alarms with high accuracy.

  In each of the above embodiments, the mobile phone is used as an example of the portable electronic device. However, the portable electronic device is not limited to the mobile phone and can be changed as appropriate. For example, the portable electronic device may be a portable terminal such as a PDA (Personal Digital Assistant).

  Further, in each of the embodiments described above, the position detection unit 10c detects the current position using GPS, but the position detection unit 10c is transmitted from another current position detection device (for example, a radio base station that communicates with a mobile phone). Information indicating the current position may be detected.

  Each of the above embodiments can be applied as an alarm system at the time of arrival at a destination station on a railway or a route bus.

  Each of the above embodiments may be executed by a computer that reads and executes a program recorded on a computer readable recording medium. In this case, the computer executes the program to the above embodiment. It functions as each included component (each means).
