  In recent years, there has been an accident in which a user of a portable terminal device such as a smartphone observes a screen of a smartphone or the like while walking on a platform at a station or the like and falls down to a track by mistake. In response to such an accident, the station calls for self-restraint on the use of smartphones while walking using on-site broadcasting, etc., but the effect is limited. In addition, there are places where a fall prevention fence is installed on the platform of the station, but installation of a fall prevention fence is not possible due to the cost and operational aspects such as the operation of trains with different door positions. Not progressing. In addition, when antenna devices are installed side by side on the center line of the platform of the station and the radio field intensity from the antenna device received by the wireless portable terminal becomes weak, alert information is sent from the antenna device to alert the user. Has been proposed.

  Hereinafter, embodiments of a control program, a control method, and a terminal device disclosed in the present application will be described in detail based on the drawings. The disclosed technology is not limited by the present embodiment. Further, the following embodiments may be appropriately combined within a consistent range.

  FIG. 1 is an explanatory diagram illustrating an example of a control system according to the embodiment. The control system 1 illustrated in FIG. 1 suppresses, for example, a user of the terminal device 10 on the train platform 2 gazing while walking on the screen of the terminal device 10 and accidentally falls on the track 3. A control system 1 illustrated in FIG. 1 includes a plurality of transmitters 5 a to 5 d and a terminal device 10. In the following description, when the transmitters 5a to 5d are not distinguished, they are referred to as transmitters 5. In FIG. 1, four transmitters 5 and one terminal device 10 are provided. However, the number of transmitters 5 and terminal devices 10 is not limited, and the control system 1 can include any number of transmitters 5 and terminals. You may have the apparatus 10.

  For example, the control system 1 installs a plurality of transmitters 5 a to 5 d along the end of the train platform 2 on the track 3 side, and transmits the radio waves 6 a to 6 d toward the home 2 side. Note that radio waves 6a to 6d in FIG. 1 represent radio wave receivable ranges. In the control system 1, when the user who owns the terminal device 10 is walking with the screen displayed or operating, and enters the range of the radio waves 6 a to 6 d, the display or operation of the terminal device 10 is performed. Restrict. For example, when the user who owns the terminal device 10 moves from the range of the radio wave 6a toward the range of the radio wave 6d (step S1), the control system 1 transmits the radio waves received by the terminal device 10 to the radio waves 6a, 6b, 6c, 6d and so on. For example, when the terminal device 10 detects that the received radio wave is switched within a predetermined time, the terminal device 10 restricts display or operation of the terminal device 10. Further, for example, when the user who owns the terminal device 10 moves to the wall side of the home 2 where no radio wave reaches from the range of the radio wave 6d (step S2), the control device 1 Remove display or operation restrictions. Thereby, the control system 1 can restrict | limit the display or operation of the terminal device 10 effectively, when the user of the terminal device 10 approaches the dangerous area near the track | truck 3 on the home 2. FIG.

  FIG. 2 is a block diagram illustrating an example of the configuration of the control system of the embodiment. As shown in FIG. 2, the control system 1 includes a plurality of transmitters 5 and a terminal device 10. For example, the transmitter 5 transmits radio waves of a wireless local area network (LAN). The transmitter 5 includes, for example, a wireless LAN wireless communication module based on a standard such as IEEE802.11a / b / g and an antenna. The transmitter 5 transmits its SSID (Service Set Identifier) as a beacon. The SSID includes, for example, a character indicating that it is the transmitter 5 of the control system 1 and a character for identifying each of the plurality of transmitters 5.

  Further, the antenna of the transmitter 5 is arranged so as to have directivity on the home side as shown in the range of the radio waves 6a to 6d in FIG. For example, the transmitter 5 adjusts the high frequency output so that the receivable range of the radio wave is 2 to 3 m from the end of the home 2 on the line 3 side. For example, when the receivable range of the radio wave is 2 to 3 m from the end of the home 2 on the line 3 side, the installation interval of the transmitters 5 can be set to 1 m. Note that the transmitter 5 may be one that conforms to another short-range wireless communication standard, for example, a wireless communication module based on the Bluetooth (registered trademark) standard. The transmitter 5 transmits a MAC (Media Access Control) address as a beacon, for example, when using a Bluetooth (registered trademark) module.

  Next, the configuration of the terminal device 10 will be described. As illustrated in FIG. 2, the terminal device 10 includes a communication unit 11, a display operation unit 12, an acceleration sensor 13, a storage unit 14, and a control unit 16. The terminal device 10 may include various functional units included in a known computer other than the functional units illustrated in FIG. 2, for example, functional units such as various input devices and audio output devices. As an example of the terminal device 10, a smartphone can be employed. The terminal device 10 may employ not only the above-described smartphone, but also a tablet terminal, a mobile communication terminal such as a mobile phone or PHS (Personal Handyphone System), or a slate terminal such as a PDA (Personal Digital Assistants). it can.

  The communication unit 11 is realized by, for example, a wireless communication module that supports a wireless LAN or the like. The communication unit 11 receives radio waves transmitted from the transmitter 5. That is, the communication unit 11 is a receiving unit. The communication unit 11 measures the radio field intensity of the received radio wave, for example, every 100 ms, and outputs it to the control unit 16 together with radio wave identification information such as SSID and the detection time. Note that the communication unit 11 may measure the radio wave intensity at an arbitrary measurement interval, for example, every 10 ms. Further, the communication unit 11 may receive radio waves transmitted from the transmitter 5 even when the terminal device 10 is set to the power saving mode.

  Moreover, the communication part 11 may be implement | achieved by the radio | wireless communication module corresponding to a mobile telephone line, for example. Further, the communication unit 11 may include a wireless communication module corresponding to another wireless communication standard, for example, a Bluetooth (registered trademark) module may be used. The communication unit 11 may use the plurality of communication standards, for example, a mobile phone line and a wireless LAN at the same time. For example, the communication unit 11 connects to the Internet (not shown) from the transmitter 5 using the mobile phone line. The transmitted wireless LAN beacon can be received. In this case, the communication unit 11 is a communication interface that is wirelessly connected to a server or the like on the Internet (not shown) and manages information communication with the server.

  The display operation unit 12 is a display device for displaying various types of information and an input device for receiving various types of operations from the user. For example, the display operation unit 12 is realized by a liquid crystal display or the like as a display device. Further, for example, the display operation unit 12 is realized by a touch panel or the like as an input device. That is, in the display operation unit 12, the display device and the input device are integrated. That is, the display operation unit 12 is a display unit and an operation input unit. The display operation unit 12 outputs an operation input by the user to the control unit 16 as operation information. The display operation unit 12 may separately provide a display device and an input device.

  The acceleration sensor 13 is, for example, a triaxial acceleration sensor that detects acceleration in each of the x, y, and z axes, and detects acceleration applied to the terminal device 10 by detecting acceleration of each axis. As the acceleration sensor 13, for example, an acceleration sensor using MEMS (Micro Electro Mechanical Systems) such as a capacitance type, a piezoresistive type, or a gas temperature distribution type can be used. The acceleration sensor 13 outputs the detected acceleration of each axis to the control unit 16 as acceleration information. The acceleration sensor 13 starts detection of acceleration when instructed to start detection of acceleration by the control unit 16, and continues to output acceleration information until instructed to stop detection of acceleration from the control unit 16. .

  The storage unit 14 is realized by, for example, a semiconductor memory device such as a RAM (Random Access Memory) or a flash memory, or a storage device such as a hard disk or an optical disk. The storage unit 14 includes a radio wave information storage unit 15. The storage unit 14 stores information used for processing in the control unit 16.

  The radio wave information storage unit 15 stores the SSID, which is identification information transmitted from each transmitter 5, the radio wave intensity of the radio wave transmitted from each transmitter 5, and the detection time of the radio wave in association with each other. FIG. 3 is a diagram illustrating an example of the radio wave information storage unit. As illustrated in FIG. 3, the radio wave information storage unit 15 includes items such as “SSID”, “radio wave intensity”, and “detection time”. The radio wave information storage unit 15 stores one record for each transmitter 5.

  “SSID” identifies the transmitter 5. “Radio wave intensity” indicates the radio wave intensity of the radio wave transmitted from the corresponding transmitter 5, and the unit is represented by “dBm”, for example. “Detection time” indicates the time when the communication unit 11 receives and detects the radio wave transmitted from the corresponding transmitter 5. The “detection time” holds, for example, the last time when the radio wave can be detected when the radio wave from the transmitter 5 cannot be detected. The “detection time” is updated with a new detection time when the radio wave from the transmitter 5 is detected again. When a Bluetooth (registered trademark) module is used for the communication unit 11, the transmitter 5 is identified using a MAC address instead of “SSID”. In this case, a list of MAC addresses of the transmitter 5 used in the control system 1 may be stored in advance, and only the MAC addresses that match the list may be stored.

  Returning to the description of FIG. 2, the control unit 16 executes, for example, a program stored in an internal storage device using a RAM as a work area by a CPU (Central Processing Unit), an MPU (Micro Processing Unit), or the like. Is realized. The control unit 16 may be realized by an integrated circuit such as an application specific integrated circuit (ASIC) or a field programmable gate array (FPGA). The control unit 16 includes a detection unit 17, a detection unit 18, a determination unit 19, and a restriction unit 20, and realizes or executes information processing functions and operations described below. The internal configuration of the control unit 16 is not limited to the configuration illustrated in FIG. 2, and may be another configuration as long as the information processing described later is performed.

  When the identification information, the radio wave intensity, and the detection time are input from the communication unit 11, the detection unit 17 stores the identification information of the transmitter 5 in the radio wave information storage unit 15. For example, the detection unit 17 updates the identification information, the radio wave intensity, and the detection time in the radio wave information storage unit 15 every 100 ms. When new identification information and the radio wave intensity and detection time corresponding to the identification information are input, the detection unit 17 stores the new transmitter 5 in a new record of the radio wave information storage unit 15.

  The detection unit 18 refers to the radio wave information storage unit 15 to detect switching of the transmitter 5 when the difference in radio wave detection time between the transmitters 5 is within a predetermined time. Here, for example, the SSID of the transmitter 5a is “DANGER_AREA_A”, the SSID of the transmitter 5b is “DANGER_AREA_B”, the SSID of the transmitter 5c is “DANGER_AREA_C”, and the SSID of the transmitter 5d is “DANGER_AREA_D” in FIGS. An example of detection will be described with reference to FIG. For example, the detection unit 18 calculates the difference in detection time between the SSIDs “DANGER_AREA_A” and “DANGER_AREA_B” illustrated in FIG. For example, when the detection unit 18 calculates the difference between the detection times of the SSIDs “DANGER_AREA_B” and “DANGER_AREA_C” illustrated in FIG. That is, the user who has the terminal device 10 is moving from the range of the radio wave 6a of the transmitter 5a to the range of the radio wave 6c of the transmitter 5c at the same speed. In the example of FIG. 3, the user of the terminal device 10 is just moving from the range of the radio wave 6c to the range of the radio wave 6d of the transmitter 5d.

  The detection unit 18 compares a predetermined time for detecting the switching of the transmitter 5 with 1.4 seconds that is a difference between detection times of “DANGER_AREA_A” and “DANGER_AREA_B”. For example, if the predetermined time is 2 seconds, the detection unit 18 detects that the radio wave transmission source has been switched from the transmitter 5a to the transmitter 5b because 1.4 seconds is within 2 seconds. The predetermined time may be an arbitrary time or may be settable by the user of the terminal device 10.

  When the detection unit 18 detects that the transmitter 5 has been switched, the detection unit 18 outputs detection information indicating the detection to the determination unit 19. When the user of the terminal device 10 further moves, the detection unit 18 similarly compares 1.4 seconds, which is a difference in detection time between “DANGER_AREA_B” and “DANGER_AREA_C”, with 2 seconds, which is a predetermined time. Then, it is detected that the radio wave source has been switched from the transmitter 5b to the transmitter 5c. When the detection unit 18 detects that the transmitter 5 has been switched, the detection unit 18 outputs detection information indicating the detection to the determination unit 19. In this way, the detection unit 18 outputs detection information to the determination unit 19 every time it detects the switching of the transmitter 5 that is a radio wave transmission source.

  Here, with reference to FIG. 4, an example of switching detection based on the relationship between the detection time when the user of the terminal device 10 is moving and the change in radio wave intensity will be described in detail. FIG. 4 is a diagram illustrating an example of a change in radio wave intensity. In FIG. 4, each transmitter 5 is indicated by an SSID. As shown in FIG. 4, for example, when the user of the terminal device 10 moves from the range of the radio wave 6a of the transmitter 5a toward the radio wave 6d of the transmitter 5d, the terminal device 10 receives from each transmitter 5. The radio field intensity changes. For example, the terminal device 10 receives only the radio wave having the SSID “DANGER_AREA_A” at the detection time “18: 31: 17.2”. The terminal device 10 receives the radio wave of the SSID “DANGER_AREA_B” from the detection time “18: 31: 17.4” when the user of the terminal device 10 moves. At this time, the radio wave intensity of the SSID “DANGER_AREA_A” is −81 dBm, and the radio wave intensity of the SSID “DANGER_AREA_B” is −107 dBm. The detection unit 18 compares -81 dBm and -107 dBm, which are the respective radio wave intensities, and determines that the user of the terminal device 10 is within the range of the SSID “DANGER_AREA_A”, that is, the radio wave 6a of the transmitter 5a.

  For example, the detection unit 18 similarly compares the radio wave intensity every 100 ms. When the user of the terminal device 10 further moves, the radio field intensity of the SSID “DANGER_AREA_A” is −93 dBm and the radio field intensity of the SSID “DANGER_AREA_B” is −91 dBm at the detection time “18: 31: 17.9”. . The detection unit 18 compares -93 dBm, which are the respective radio wave strengths, with -91 dBm, and determines that the user of the terminal device 10 is within the range of the SSID “DANGER_AREA_B”, that is, the radio wave 6b of the transmitter 5b. In other words, for example, when the radio field intensity of the SSID “DANGER_AREA_B” becomes stronger than the radio field intensity of the SSID “DANGER_AREA_A” within a predetermined time after the reception of the radio wave of the SSID “DANGER_AREA_B” starts, It is detected that the machine 5 has been switched.

  In the above description, the radio wave strengths of the two transmitters 5 are compared, and the timing at which the radio wave strengths are switched is the timing at which the transmitter 5 is switched. However, other timings may be used. When the detection unit 17 detects the detection unit 17 for a predetermined number of times or more, for example, seven or more times continuously after the reception of the radio wave of the transmitter 5 that has become a reception enabled state from the reception disabled state, for example, It may be detected that the machine 5 has been switched. The predetermined number of times can be any number. Thereby, the detection part 18 can detect switching of the transmitter 5 suitable according to an installation environment.

  In addition, the detection unit 18 may compare the radio field intensity for the transmitter 5 detected by the detection unit 17 continuously, for example, a predetermined number of times or more, for example, 5 times or more. The predetermined number of times can be any number. Thereby, since the detection part 18 can exclude the electromagnetic wave of the transmitter 5 which receives temporarily in the vicinity of the boundary of the receivable range of an electromagnetic wave, it can suppress detecting the switching of the transmitter 5 accidentally. .

  Returning to the description of FIG. 2, when the detection information is input from the detection unit 18, the determination unit 19 acquires acceleration information input from the acceleration sensor 13. The determination unit 19 determines that the user is walking when the input acceleration information has a predetermined constant period. The determination unit 19 determines that the user is not walking when the input acceleration information is not a predetermined constant period. The determination unit 19 outputs the determination result to the restriction unit 20. In addition, the determination part 19 can use the period of a user's walk pattern based on the acceleration information of each axis | shaft as a predetermined fixed period determined to be walking. In addition, the detection method used for the pedometer etc. which are mounted in the existing mobile telephone terminal etc. can be applied to the detection of a predetermined fixed period, for example.

  The restriction unit 20 generates a display screen to be displayed on the display operation unit 12. FIG. 5 is a diagram illustrating an example of a display screen. As illustrated in FIG. 5, for example, the restriction unit 20 generates a display screen 31 on which a web browser is displayed in addition to the radio wave status and operation icons, and displays the display screen 31 on the display operation unit 12 of the terminal device 10.

  In addition, for example, when the determination result indicating that the user is walking is input from the determination unit 19 while the display screen 31 is displayed on the display operation unit 12, the restriction unit 20 displays the display operation unit 12. Limit operations. That is, the limiting unit 20 is a control unit. The control means may include the detection unit 17 and the detection unit 18. FIG. 6 is a diagram illustrating an example of a state where the screen display is turned off. As illustrated in FIG. 6, for example, the restriction unit 20 restricts the display of the display operation unit 12 by turning off the display of the display operation unit 12 and setting the display operation unit 12 to the unlit state 32.

  For example, the restriction unit 20 may display a warning on the display operation unit 12. FIG. 7 is a diagram illustrating an example of a display screen that displays a warning. As illustrated in FIG. 7, the restriction unit 20 restricts the display of the display operation unit 12 by, for example, superimposing a warning 33 on the display screen 31 displayed on the display operation unit 12.

  The restriction unit 20 restricts operations on the terminal device 10 by restricting input to the touch panel of the display operation unit 12, that is, restricting operation information input from the display operation unit 12, for example. You may do it. At this time, for example, the restriction unit 20 can be configured not to restrict operations that can be performed without the user viewing the screen, such as a volume switch. For example, the restriction unit 20 may perform warning display and input restriction on the touch panel at the same time.

  For example, when the determination result indicating that the user is not walking is input from the determination unit 19 while the display screen 31 is displayed on the display operation unit 12, the restriction unit 20 displays or operates the display operation unit 12. The display screen 31 is continuously displayed without limiting the above. Further, even when the detection unit 18 does not detect switching of the transmitter 5 within a predetermined time, the restriction unit 20 does not restrict the display or operation of the display operation unit 12 and continuously displays the display screen 31.

  The restriction unit 20 inputs the detection information to the restriction unit 20 when the detection unit 18 detects switching of the transmitter 5 within a predetermined time, that is, when detection information is output from the detection unit 18. Thus, the display or operation of the display operation unit 12 may be limited. In this case, for example, even the terminal device 10 that does not have an acceleration sensor can restrict screen display or operation while walking.

  Next, operation | movement of the control system 1 of an Example is demonstrated. FIG. 8 is a flowchart illustrating an example of the restriction process. Note that the restriction process illustrated in FIG. 8 indicates a process in the terminal device 10 of the control system 1. When the identification information, the radio wave intensity, and the detection time are input from the communication unit 11, the detection unit 17 of the terminal device 10 stores the identification information of the transmitter 5 in the radio wave information storage unit 15. The detection unit 17 determines whether a new radio wave has been detected (step S11).

  When a new radio wave is detected (step S11: affirmative), the detection unit 17 adds the detected radio wave SSID to the radio wave information storage unit 15 (step S12). That is, the detection unit 17 stores the new identification information and the radio wave intensity and the detection time corresponding to the identification information in a new record of the radio wave information storage unit 15. When the detection unit 17 does not detect a new radio wave (No at Step S11), the detection unit 17 proceeds to Step S13.

  The detection unit 18 refers to the radio wave information storage unit 15 and determines whether or not switching of the transmitter 5 is detected within a predetermined time (step S13). When detecting the switching of the transmitter 5 within a predetermined time (step S13: Yes), the detection unit 18 outputs detection information indicating the detection to the determination unit 19. When the detection information is input from the detection unit 18, the determination unit 19 acquires the acceleration information input from the acceleration sensor 13 (step S14).

  The determination unit 19 determines whether the user of the terminal device 10 is walking based on the input acceleration information (step S15). When the user of the terminal device 10 is walking (Yes at Step S15), the determination unit 19 outputs a determination result indicating that the user is walking to the restriction unit 20. When the determination result indicating that the user is walking is input from the determination unit 19, for example, the restriction unit 20 turns off the screen of the display operation unit 12 and restricts the display (step S16).

  When the user of the terminal device 10 is not walking (No at Step S15), the determination unit 19 outputs a determination result indicating that the user is not walking to the restriction unit 20. When the determination result indicating that the user is not walking is input from the determination unit 19, the restriction unit 20 does not restrict the display of the display operation unit 12 and continuously displays the displayed screen (step S <b> 17). Similarly, when the detection unit 18 does not detect switching of the transmitter 5 within a predetermined time (Step S13: No), the restriction unit 20 displays the display operation unit 12 without restricting the display. The screen is continuously displayed (step S17). The terminal device 10 repeatedly executes step S11 to step S17 at a predetermined cycle. In addition, the predetermined cycle of repetition can be set to an arbitrary cycle, and can be set to 100 ms in accordance with the measurement of the radio wave intensity of the communication unit 11, for example. Thereby, the display or operation of the terminal device 10 at the home 2 can be effectively limited. Further, the terminal device 10 can determine whether the user is walking or on the train by using the acceleration information in addition to the detection of the switching of the transmitter 5 within a predetermined time. In such a case, it is possible not to restrict display or operation. For this reason, a user's troublesomeness can be reduced more.

  Thus, the terminal device 10 receives the transmitter 5 of the radio wave transmitted from the plurality of transmitters 5 installed along the train platform 2 and received using the receiving means included in the terminal device 10. When it is detected that the switching has been performed within a predetermined time, the display unit included in the terminal device 10 is displayed or an operation on the terminal device 10 is restricted. As a result, the display or operation of the terminal device 10 at the home 2 can be effectively limited.

  Further, the terminal device 10 limits the display on the display unit by displaying a warning on the display unit. As a result, it is possible to notify the user that the display or operation during walking on the home 2 is restricted.

  The terminal device 10 limits the display on the display unit by turning off the display on the display unit. As a result, the display of the terminal device 10 at the home 2 can be effectively limited.

  Moreover, the terminal device 10 restricts the operation by restricting input to the touch panel provided in the display unit. As a result, the operation of the terminal device 10 at the home 2 can be effectively limited.

  Further, the terminal device 10 compares the radio wave intensity of the radio wave transmitted from the transmitter 5 and detects that it has switched. As a result, even when the user moves in a state where radio waves from the plurality of transmitters 5 can be received, the display or operation of the terminal device 10 at the home 2 can be effectively limited.

  Moreover, the terminal device 10 detects the radio wave transmitted from the transmitter 5 at a predetermined cycle, and detects that the transmitter 5 that has detected the radio wave continuously detected a predetermined number of times or more is switched. As a result, since the radio wave of the transmitter 5 that is temporarily received can be excluded in the vicinity of the boundary of the radio wave receivable range, it is possible to suppress erroneous detection of switching of the transmitter 5.

  In the above-described embodiment, it is determined whether or not the switching of the transmitter 5 is detected within a predetermined time, and then it is determined whether or not walking is performed using the acceleration information. However, the present invention is not limited to this. For example, it may be determined whether or not switching of the transmitter 5 is detected within a predetermined time after determining whether or not the user is walking using acceleration information. Further, the display or operation of the terminal device 10 may be limited only by determining whether or not switching of the transmitter 5 is detected within a predetermined time without using the acceleration information.

  Moreover, although the said Example demonstrated the case where a train passed along the track | line 3, it is not limited to this. For example, the present invention is not limited to a train, and may be a case where a train such as a diesel car or a passenger car pulled by a locomotive passes. Moreover, you may install the transmitter 5 not only on the track 3 side of the platform 2 but near the stairs and the escalator. Furthermore, you may make it install the transmitter 5 not only in the home 2 but in a sightseeing spot etc. in the place where fall, such as an observation deck and a cliff, is assumed. Thereby, for example, when the user stops and takes a picture or the like, the terminal device 10 can be operated, and can be limited to an operation while walking.

  Moreover, in the said Example, when the user of the terminal device 10 was walking, although the display or operation of the terminal device 10 was restrict | limited, it is not limited to this. For example, when the user of the terminal device 10 runs, the display or operation of the terminal device 10 may be restricted.

  In the above embodiment, each unit has been described as a component of a functional unit, but the present invention is not limited to this. For example, an operating system (OS) may be operated on the control unit 16, and the detection unit 17, the detection unit 18, the determination unit 19, and the restriction unit 20 may be configured as applications that operate on the OS. In addition, the application may be always activated after the terminal device 10 is turned on, or may be activated simultaneously when an application that uses a screen is used.

  In addition, each component of each part illustrated does not necessarily need to be physically configured as illustrated. In other words, the specific form of distribution / integration of each unit is not limited to that shown in the figure, and all or a part thereof may be functionally or physically distributed / integrated in arbitrary units according to various loads or usage conditions. Can be configured. For example, the detection unit 17 and the detection unit 18 may be integrated.

  Furthermore, various processing functions performed by each device may be executed entirely or arbitrarily on a CPU (or a microcomputer such as an MPU or MCU (Micro Controller Unit)). In addition, various processing functions may be executed in whole or in any part on a program that is analyzed and executed by a CPU (or a microcomputer such as an MPU or MCU) or on hardware based on wired logic. Needless to say, it is good.
