Summary of the Invention
Problems to be Solved by the Invention
[0004] In recent years, there are users who are obsessed with operating a terminal such as a smartphone while walking and cannot recognize that they are staying inside a level crossing. In order to prevent accidents caused by such users, it is preferable to suppress the user from staying inside the level crossing. However, the conventional system notifies the train of the occurrence of an abnormality at the level crossing, and there is a problem that it cannot suppress the user staying inside the level crossing from continuing to stay inside.
[0005] Therefore, the present invention has been made in view of these points, and an object thereof is to suppress a user staying inside a level crossing from continuing to stay inside.
Means for Solving the Problems
[0006] A terminal according to a first aspect of the present invention is a terminal used by a user, comprising: a location information acquisition unit that acquires terminal location information indicating the location of the terminal; a storage unit that stores level crossing location information indicating the location of a railway level crossing; a detection unit that detects the alarm sound of the level crossing; and a notification unit that, based on the level crossing location information stored in the storage unit, determines that a level crossing exists within a predetermined range from the terminal location indicated by the terminal location information acquired by the location information acquisition unit, and when the detection unit detects the alarm sound, it notifies the user.
[0007] The terminal has a speed determination unit that determines the speed at which the terminal is moving, and the notification unit may notify the user when it determines, based on the level crossing location information stored in the storage unit, that a level crossing exists within a predetermined range from the location of the terminal indicated by the terminal location information acquired by the location information acquisition unit, and that the speed at which the terminal is moving is less than or equal to the predetermined speed, and the detection unit detects the alarm sound.
[0008] The storage unit stores railway crossing location information indicating the location of a railway crossing and the type of the crossing in association with each other. The notification unit may, based on the railway crossing location information and the type of the crossing stored in the storage unit, determine that a railway crossing of a predetermined type exists within a predetermined range from the location of the terminal indicated by the terminal location information acquired by the location information acquisition unit, and notify the user regardless of whether the detection unit has detected the alarm sound.
[0009] When the detection unit detects the horn of a railway vehicle and the notification unit notifies the user, the detection unit may enhance the notification to the user when it detects the horn of the railway vehicle.
[0010] The notification unit may determine the direction of the user's movement based on the terminal location information at multiple times acquired by the location information acquisition unit, and if it determines, based on the level crossing location information stored in the storage unit, that a level crossing exists within a predetermined range from the terminal location indicated by the terminal location information acquired by the location information acquisition unit, it may determine whether the user is moving away from the level crossing based on the location of the level crossing, the location of the terminal indicated by the terminal location information, and the direction of the user's movement, and if it determines that the user is not moving away from the level crossing, it may notify the user.
[0011] The notification unit may identify the user's travel route based on the terminal location information at multiple times acquired by the location information acquisition unit, and if it determines, based on the level crossing location information stored in the storage unit, that a level crossing exists within a predetermined range from the terminal location indicated by the terminal location information acquired by the location information acquisition unit, it may determine whether the user is inside the level crossing based on the location of the level crossing and the identified user's travel route, and if it determines that the user is inside the level crossing, it may notify the user.
[0012] The notification unit may notify the user by displaying a notification screen for the user at the forefront of the terminal's display unit. The notification unit may determine whether the sound output from the terminal is being output to the earphones, and if it determines that the sound is being output to the earphones, it may output a sound to notify the user to the earphones.
[0013] The detection unit determines whether the user is a user who uses the terminal while walking or a user who has a high tendency to use the terminal while walking. The notification unit may, when it determines that a railroad crossing exists within a predetermined range from the terminal's location indicated by the terminal location information, notify the user if the detection unit detects the alarm sound, provided that it has determined that the user is a user who uses the terminal while walking or a user who has a high tendency to use the terminal while walking.
[0014] A notification system according to a second aspect of the present invention is a notification system comprising a terminal and an information processing device, wherein the information processing device includes a location information acquisition unit that acquires a plurality of terminal location information indicating the location of a plurality of terminals used by a plurality of users, a direction identification unit that identifies the orientation of each user of the plurality of terminals based on the plurality of terminal location information acquired for each of the plurality of terminals, and a transmission unit that acquires terminal location information of the terminal and a direction acquisition request from the terminal requesting the acquisition of direction information indicating the orientation of users in the vicinity of the terminal, identifies terminals in the vicinity of the terminal based on the terminal location information of the terminal, and transmits to the terminal the direction information indicating the orientation of the user identified by the direction identification unit to each of the identified surrounding terminals, and the terminal has the railroad crossing location information stored in the storage unit Based on this, if a level crossing exists within a predetermined range from the terminal location information acquired by the location information acquisition unit, the direction of the terminal user is determined based on the terminal location information acquired by the location information acquisition unit, and the terminal location information and the direction acquisition request are transmitted to the information processing device, and the direction acquisition unit acquires direction information indicating the direction of users in its vicinity from the information processing device. The notification unit, based on the level crossing location information stored in the storage unit, determines that a level crossing exists within a predetermined range from the terminal location indicated by the terminal location information acquired by the location information acquisition unit, and when the detection unit detects the alarm sound, it notifies the user, provided that the agreement rate between the identified user's direction and the direction of surrounding users acquired by the direction acquisition unit is below a predetermined threshold. [Effects of the Invention]
[0015] According to the present invention, it is possible to suppress users who remain inside a railway crossing from continuing to stay inside the railway crossing. [Brief explanation of the drawing]

[Figure 4] It is a flowchart showing an example of the processing flow of the terminal. [Figure 5] It is a diagram showing the functional configuration of the information processing apparatus. [Figure 6] It is a diagram showing the functional configuration of the terminal according to the second embodiment.
Mode for Carrying Out the Invention
[0017] <The First Embodiment> [Overview of Terminal 1] FIG. 1 is a diagram showing an overview of Terminal 1 according to the first embodiment. Terminal 1 is a computer that can be carried by a user, such as a smartphone, a tablet, or a smartwatch, and is used to prevent the user from staying inside a railway crossing continuously.
[0018] Terminal 1 acquires terminal position information indicating its own position at regular intervals (1 in FIG. 1). In addition, Terminal 1 stores crossing position information indicating the position of a railway crossing. Terminal 1 collects the sound around Terminal 1 and detects the warning sound of the crossing (2 in FIG. 1). When Terminal 1 determines that there is a crossing within a predetermined range from its own position based on the crossing position information and the acquired terminal position information, and detects a warning sound, for example, it notifies the user that the user is inside the crossing (3 in FIG. 1).
[0019] By doing so, when the probability that the user does not notice that they are waiting inside the crossing when the crossing is closed due to being distracted by Terminal 1 is high, Terminal 1 can make the user recognize that they are inside the crossing, and can increase the probability that the user takes refuge outside the crossing. Therefore, Terminal 1 can prevent a user staying inside the crossing from continuing to stay inside the crossing.
[0020] [Functional Configuration of Terminal 1] Next, the details of the configuration of terminal 1 will be described. Figure 2 is a diagram showing the functional configuration of terminal 1 according to the first embodiment. Terminal 1 has an operation unit 11, a sound collection unit 12, a display unit 13, a communication unit 14, a storage unit 15, and a control unit 16.
[0021] The operation unit 11 is an operating device such as a touch panel or buttons that accepts user input. The sound collection unit 12 is, for example, a microphone that collects sounds from the surrounding area of terminal 1. The display unit 13 is a display that shows various information. The communication unit 14 is a communication interface for sending and receiving data with external devices via a communication network such as the internet or a mobile phone line.
[0022] The memory unit 15 is a storage medium for storing various types of data, and includes ROM (Read Only Memory), RAM (Random Access Memory), etc. The memory unit 15 stores the program to be executed by the control unit 16. The memory unit 15 also stores a notification program that causes the control unit 16 to function as a location information acquisition unit 161, a detection unit 162, a speed determination unit 163, and a notification unit 164.
[0023] Furthermore, the memory unit 15 stores level crossing information, including level crossing location information that indicates the location of a railway level crossing. Figure 3 shows an example of level crossing information. Level crossing information is information that associates, for example, a level crossing ID for identifying a level crossing with level crossing location information that indicates the latitude and longitude of the center position of the level crossing. The center position of a level crossing is, for example, the midpoint between a pair of level crossings provided between a road and a railway track.
[0024] The control unit 16 is, for example, a CPU (Central Processing Unit). The control unit 16 functions as a location information acquisition unit 161, a detection unit 162, a speed determination unit 163, and a notification unit 164 by executing a notification program stored in the memory unit 15.
[0025] The location information acquisition unit 161 acquires terminal location information indicating the location of terminal 1. For example, terminal 1 has a receiving unit (not shown) that receives signals from GPS (Global Positioning System) satellites to determine the location of terminal 1. The location information acquisition unit 161 acquires terminal location information at predetermined time intervals by determining the location of terminal 1 based on the signals received by the receiving unit at predetermined time intervals.
[0026] The detection unit 162 detects the warning sound of a level crossing. For example, the memory unit 15 stores characteristic information that indicates the characteristics of the warning sounds of multiple types of level crossings. The detection unit 162 analyzes the sound collected by the sound collection unit 12 and extracts the characteristic information of the collected sound. The detection unit 162 detects that a level crossing warning sound is sounding if the extracted characteristic information matches or is similar to any of the characteristic information of the warning sounds of multiple types of level crossings stored in the memory unit 15.
[0027] The speed determination unit 163 determines the speed of movement of terminal 1. For example, terminal 1 has an acceleration sensor (not shown) that detects the acceleration of terminal 1. The speed determination unit 163 determines the speed of movement of terminal 1 by calculating the speed of movement of terminal 1 based on the acceleration detected by the acceleration sensor. The speed determination unit 163 may also determine the speed of movement of terminal 1 based on a plurality of terminal location information acquired by the location information acquisition unit 161 at predetermined time intervals and the time interval at which the plurality of terminal location information was acquired.
[0028] The notification unit 164, based on the level crossing location information stored in the memory unit 15, notifies the user when the detection unit 162 detects a level crossing alarm sound if it determines that a level crossing exists within a predetermined range (for example, within 15m) from the location of terminal 1 indicated by the terminal location information acquired by the location information acquisition unit 161. The notification unit 164, based on the level crossing location information, notifies the user when the detection unit 162 detects a level crossing alarm sound if it determines that a level crossing exists within a predetermined range from the location of terminal 1 and that the movement speed of terminal 1, as determined by the speed determination unit 163, is below a predetermined speed.
[0029] For example, the notification unit 164 refers to the level crossing information and determines whether the center position of the level crossing indicated by the level crossing location information is within a predetermined range from the position of terminal 1 indicated by the terminal location information, thereby determining whether the user of terminal 1 is inside the level crossing. If the notification unit 164 determines that the user is inside the level crossing and that the movement speed of terminal 1 is below a predetermined speed, and the detection unit 162 detects the level crossing alarm sound, it notifies the user.
[0030] The information to be notified to the user may be, for example, a warning indicating that the user may be inside a level crossing and that danger is imminent to the user, but is not limited to this; it may also be information indicating that a railway vehicle is approaching the level crossing. The notification unit 164 notifies the user of the warning information, for example, by displaying the warning information on the display unit 13. If the terminal 1 and an electronic device worn by the user, such as a smartwatch, are in a communication-enabled relationship, the notification unit 164 may also push the warning information to the electronic device.
[0031] Alternatively, the notification unit 164 may notify the user by displaying a notification screen for the user on the display unit 13. In this way, terminal 1 can reliably notify the user when the user is looking at the display unit 13.
[0032] Furthermore, the notification unit 164 may determine whether the sound output from terminal 1 is being output to wired or wireless earphones. If the notification unit 164 determines that the sound output from terminal 1 is being output to wired or wireless earphones, it notifies the user of the warning information by outputting a sound indicating warning information to the earphones. In this way, warning information can be notified to the user even if the user is not looking at the screen and is listening to music or the like.
[0033] Generally, level crossings are classified as Type 1 level crossings, which are equipped with automatic barriers and warning devices. However, in addition to Type 1 level crossings, there are also Type 3 level crossings, which do not have warning devices and do not emit warning sounds, and Type 4 level crossings, which do not have warning devices or barriers and are only equipped with level crossing warning signs. In the case of Type 3 and Type 4 level crossings, terminal 1 cannot detect warning sounds and therefore cannot notify the user of warning information based on the warning sounds.
[0034] In contrast, the storage unit 15 may store level crossing information that associates the type of level crossing with the level crossing location information. The notification unit 164 then refers to the level crossing information and, if the level crossing location information exists within a predetermined range from the terminal location information acquired by the location information acquisition unit 161, identifies the type of level crossing corresponding to that location information. If it is a level crossing of a predetermined type that does not emit an alarm sound, i.e., a Type 3 or Type 4 level crossing, it notifies the user of warning information regardless of whether an alarm sound is detected. In this way, terminal 1 can prevent the user from remaining in a level crossing where no alarm is installed.
[0035] Furthermore, the detection unit 162 may also detect the horn of a railway vehicle, and the notification unit 164 may, when notifying the user, enhance the notification to the user if the detection unit 162 detects the horn of a railway vehicle. In this case, the notification unit 164 not only displays the warning information on the display unit 13, but also enhances the notification to the user by outputting a sound indicating the warning information to the earphones, provided that the sound output from terminal 1 is output to the earphones. The notification unit 164 may also enhance the notification to the user by vibrating terminal 1. In this way, terminal 1 can increase the probability that the user will notice that a railway vehicle is approaching.
[0036] Furthermore, the notification unit 164 may determine the user's direction of movement based on terminal location information at multiple times acquired by the location information acquisition unit 161. In this case, if the notification unit 164 determines, based on the level crossing location information, that a level crossing exists within a predetermined range from the position of terminal 1 indicated by the terminal location information, it will determine whether the user is moving away from the level crossing based on the position of the level crossing, the position of terminal 1, and the user's direction of movement. The notification unit 164 may then notify the user if it determines that the user is not moving away from the level crossing, and may not notify the user if it determines that the user is moving away from the level crossing. In this way, terminal 1 can avoid being falsely warned when the user is not staying within the level crossing.
[0037] Furthermore, the notification unit 164 may identify the user's travel route based on terminal location information at multiple times acquired by the location information acquisition unit 161. If the notification unit 164 determines, based on the level crossing location information stored in the storage unit 15, that a level crossing exists within a predetermined range from the location of terminal 1 indicated by the acquired terminal location information, it may determine whether the user is inside the level crossing based on the location of the level crossing and the identified user's travel route.
[0038] For example, the notification unit 164 determines, based on the location of the level crossing and the identified user's travel path, whether the user has reached a predetermined range from the level crossing by traveling along the road. If the notification unit 164 determines that the user is within the level crossing, it may notify the user; if it determines that the user is not within the level crossing, it may not notify the user. In this way, for example, if the user is walking on the platform and approaches the level crossing, the notification unit 164 may determine that the user is not within the level crossing and notify the user of the warning information.
[0039] Furthermore, the detection unit 162 may determine whether the user is a dependent user, meaning the user is using the terminal 1 while walking or has a high tendency to use the terminal 1 while walking. For example, the detection unit 162 determines whether the user is walking based on the acceleration detected by the acceleration sensor provided in the terminal 1, and if it determines that the user is walking, it determines that the user is a dependent user if the frequency of screen display on the display unit 13 of the terminal 1 exceeds a predetermined threshold.
[0040] Furthermore, if the notification unit 164 determines that a level crossing exists within a predetermined range from the location of terminal 1 indicated by the terminal location information, and the detection unit 162 detects an alarm sound, it may notify the user of warning information, provided that it has determined that the user is an addicted user. In addition, if the notification unit 164 determines that a level crossing exists within a predetermined range from the terminal location information and the detection unit 162 detects an alarm sound, and it has determined that the user is an addicted user, it may notify the user of the warning information with greater emphasis than when it has determined that the user is not an addicted user. In this way, if the user is a user who is not easily aware of their surroundings, the user can be made aware of the danger.
[0041] [flowchart] Next, we will explain the processing flow of terminal 1. Figure 4 is a flowchart showing an example of the processing flow of terminal 1. The flowchart shown in Figure 4 is executed at predetermined time intervals (for example, every 3 seconds).
[0042] First, the location information acquisition unit 161 acquires terminal location information indicating the location of terminal 1 (S1). Next, the notification unit 164 determines whether the location of terminal 1 indicated by the terminal location information is within a predetermined range from the level crossing location (S2). If the notification unit 164 determines that the location of terminal 1 is within the predetermined range from the level crossing location (YES in S2), it proceeds to S3. Then, in S3, the speed determination unit 163 determines the speed of movement of terminal 1. On the other hand, if it determines that the location of terminal 1 is not within the predetermined range from the level crossing location (NO in S2), the process related to this flowchart is terminated.
[0043] In S4, the notification unit 164 determines whether the movement speed of terminal 1, as determined by the speed determination unit 163, is below a predetermined speed. If the notification unit 164 determines that the movement speed of terminal 1 is below the predetermined speed (YES in S4), it proceeds to S5. If it determines that the movement speed of terminal 1 exceeds the predetermined speed (NO in S4), it terminates the process related to this flowchart.
[0044] In S5, the notification unit 164 determines whether the detection unit 162 has detected the level crossing alarm sound. If the notification unit 164 determines that the detection unit 162 has detected the level crossing alarm sound (YES in S5), it proceeds to S6 and notifies the user of the warning information. On the other hand, if the notification unit 164 determines that the detection unit 162 has not detected the level crossing alarm sound (NO in S5), it terminates the process related to this flowchart.
[0045] In S7, the notification unit 164 determines whether the detection unit 162 has detected the horn. If the notification unit 164 determines that the detection unit 162 has detected the horn (YES in S7), it proceeds to S8 and emphasizes the notification of the warning information. On the other hand, if the notification unit 164 determines that the detection unit 162 has not detected the horn (NO in S7), it terminates the process related to this flowchart.
[0046] [Effects of terminal 1 in the first embodiment] As described above, the terminal 1 according to the first embodiment acquires terminal location information indicating the location of terminal 1, and based on the level crossing location information, if it determines that a level crossing exists within a predetermined range from the location of terminal 1 indicated by the acquired terminal location information, it detects the level crossing alarm sound and notifies the user. In this way, terminal 1 can prevent users who are staying inside the level crossing from remaining inside the level crossing.
[0047] <Second Embodiment> In the first embodiment, terminal 1 alone determined whether the user of terminal 1 was inside the railroad crossing based solely on the location of terminal 1. In contrast, the second embodiment differs from the first embodiment in that, in a notification system having an information processing device 2 and multiple terminals 1, terminal 1 acquires orientation information indicating the orientation of multiple surrounding terminals, and determines whether the user of terminal 1 is inside the railroad crossing based on the orientation information. The notification system according to the second embodiment will be described below. Note that explanations of parts that are the same as in the first embodiment will be omitted as appropriate.
[0048] In the second embodiment, the notification system comprises an information processing device 2 and a plurality of terminals 1. The information processing device 2 is a server capable of communicating with the plurality of terminals 1 via a communication network such as the Internet or a mobile phone line.
[0049] Figure 5 shows the functional configuration of the information processing device 2. The information processing device 2 includes a communication unit 21, a storage unit 22, and a control unit 23.
[0050] The communication unit 21 and communication unit 14 are communication interfaces for sending and receiving data with external devices such as terminal 1 via communication networks such as the internet or mobile phone lines. The storage unit 22 is a storage medium for storing various types of data, and includes ROM, RAM, hard disk, etc. The storage unit 22 stores programs to be executed by the control unit 23. The storage unit 22 stores programs that cause the control unit 23 to function as a location information acquisition unit 231, a direction identification unit 232, and a transmission unit 233.
[0051] The control unit 23 is, for example, a CPU. The control unit 23 functions as a location information acquisition unit 231, a direction identification unit 232, and a transmission unit 233 by executing a program stored in the memory unit 22.
[0052] The location information acquisition unit 231 acquires multiple pieces of terminal location information indicating the location of multiple terminals 1 used by multiple users. For example, the location information acquisition unit 231 acquires a terminal ID as terminal identification information to identify terminal 1, and terminal location information from each of the multiple terminals 1 at predetermined time intervals.
[0053] The orientation identification unit 232 identifies the orientation of each user of each of the multiple terminals 1 based on multiple terminal location information acquired for each of the multiple terminals 1. The orientation identification unit 232 identifies the orientation of each user of each of the multiple terminals 1 by identifying the orientation of the user of each terminal 1 based on the change in the position of the terminal 1 indicated by multiple terminal location information acquired within a predetermined time from the current time.
[0054] The transmitting unit 233 obtains from terminal 1 terminal location information and a direction acquisition request requesting the acquisition of direction information indicating the orientation of users around terminal 1. Then, based on the acquired terminal location information of terminal 1, the transmitting unit 233 identifies other terminals 1 around terminal 1 and transmits direction information indicating the orientation of the users identified by the direction identification unit 232 to each of the identified surrounding terminals 1. As a result, terminal 1 can identify the orientation of users in its vicinity.
[0055] Figure 6 shows the functional configuration of terminal 1 according to the second embodiment. Terminal 1 further includes a direction acquisition unit 165. Based on the level crossing location information stored in the storage unit 15, if a level crossing exists within a predetermined range from the location of terminal 1 indicated by the terminal location information acquired by the location information acquisition unit 161, the direction acquisition unit 165 identifies the orientation of the user of terminal 1 based on the terminal location information acquired by the location information acquisition unit 161, and transmits the terminal location information and a direction acquisition request to the information processing device 2. The direction acquisition unit 165 then acquires direction information from the information processing device 2 indicating the orientation of users in its vicinity.
[0056] Based on the level crossing location information stored in the memory unit 15, the notification unit 164 determines that a level crossing exists within a predetermined range from the location of terminal 1 indicated by the terminal location information acquired by the location information acquisition unit 161. When the detection unit 162 detects an alarm sound, the notification unit 164 notifies the user of warning information, provided that the agreement rate between the user's orientation identified by the orientation acquisition unit 165 and the orientation of surrounding users acquired by the orientation acquisition unit 165 is below a predetermined threshold.
[0057] [Effects of terminal 1 in the second embodiment] In this way, terminal 1 of the second embodiment can warn the user if the user is facing a different direction from several other users waiting outside the level crossing for a train to pass, and there is a high probability that the user is waiting inside the level crossing.
[0058] Furthermore, this invention will make it possible to contribute to Goal 9 of the United Nations-led Sustainable Development Goals (SDGs), "Build resilient infrastructure, promote inclusive and sustainable industrialization and foster innovation."
[0059] Although the present invention has been described above using embodiments, the technical scope of the present invention is not limited to the scope described in the above embodiments, and various modifications and changes are possible within the scope of its gist. For example, all or part of the apparatus can be configured by functionally or physically distributing and integrating in any unit. Furthermore, new embodiments resulting from any combination of multiple embodiments are also included in the embodiments of the present invention. The effects of the new embodiments resulting from the combinations are combined with the effects of the original embodiments. [Explanation of Symbols]
