  There is known a mobile orb that allows orbs to move. Since the mobile orbit can be installed anywhere, it is difficult to register its location information in advance in an electronic device or the like and inform the user of its presence.

  Further, a laser type orbit that measures the traveling speed of a vehicle by irradiating laser light instead of microwaves is conceivable. Laser light has higher directivity than microwaves, and it is difficult for an electronic device installed in a moving vehicle to receive the laser light at a long distance. It is possible to receive laser light from a mobile orbit at a short distance, but even if the laser is received several tens of meters before the mobile orvis and the driver is notified, the driver will May not be sufficiently reduced, and the vehicle overspeed may not be sufficiently suppressed.

For this reason, the light receiving position and the position of the mobile orbit 10 are close to each other, and in this embodiment, the light receiving position information is treated as the position information of the mobile orbit 10.

  On the other hand, the light reception time information is information indicating the time when the laser light from the mobile orb 10 is received by the laser light receiving unit 22. The time when light is received here is not limited to the time when light is received in a strict sense, and may be a time slightly before or after the time when light is received.

[2. processing]
Next, various processes executed by the control units 25 and 35 of the electronic devices 20 and 30 will be described. Both control units 25 and 35 execute the same processing. In the following, the public line transmission process shown in FIG. 2 and the specific low power transmission process shown in FIG. 3 will be described as processes executed by the control unit 25 of the electronic device 20 in accordance with the situation shown in FIG. The public line reception process shown in FIG. 3, the specific low power reception process shown in FIG. 4, and the alarm process shown in FIG. 6 will be described as processes executed by the control unit 35 of the electronic device 30.

[2-1. Public line transmission processing]
First, public line transmission processing executed by the control unit 25 of the electronic device 20 will be described with reference to the flowchart of FIG. The public line transmission process is periodically executed while the electronic device 20 is powered on.

  In SA01, the control unit 25 determines whether or not the laser light is received by the laser light receiving unit 22. As the laser light received here, the laser light emitted from the movable orbit 10 is assumed.

  If the control unit 25 determines that the laser light is received by the laser light receiving unit 22 in SA01, the control unit 25 proceeds to SA02 and causes the wireless communication unit 23 to transmit data to the server 60 via the public line 70. The data here includes light reception position information indicating the current position of the electronic device 20 when laser light is received by the laser light receiving unit 22 in SA01, and light reception time information indicating the time when the laser light is received. , Is included.

  Further, as described above, the control unit 25 uses the tethering function of the portable information terminal 40 to connect to the public line 70. Note that when the tethering function of the portable information terminal 40 cannot be used (such as when the tethering function is not valid), the control unit 25 ends the public line transmission process without transmitting data. As described above, in this embodiment, when the laser light is received by the laser light receiving unit 22, data including the light receiving position information and the like is automatically transmitted to the server 60 via the public line 70.

  In the case of the microwave type orbit, there are various types of microwaves, and it is necessary to select what microwaves the user has received and manually transmit them to the server 60. On the other hand, when the laser beam is received, the laser beam is highly likely to be the laser beam of the mobile orbit 10 and can be automatically transmitted to the server 60.

When executing the SA02, the control unit 25 ends the public line transmission process of FIG.
On the other hand, when determining that the laser beam is not received by the laser light receiving unit 22 in SA01 described above, the control unit 25 skips SA02 and ends the public line transmission processing. That is, when it is determined that the laser beam is not received, the data is not transmitted to the server 60.

[2-2. Specific low power transmission processing]
Next, the specific low power transmission process executed by the control unit 25 will be described with reference to the flowchart of FIG. The specific low power transmission process is periodically executed while the power of the electronic device 20 is on.

  First, in SB01, the control unit 25 determines whether or not laser light is received by the laser light receiving unit 22. As the laser light received here, the laser light emitted from the movable orbit 10 is assumed.

  When the control unit 25 determines that the laser light is received by the laser light receiving unit 22 in SB01, the control unit 25 proceeds to SB02, and transmits the data to the wireless communication unit 23 by the specific low power wireless device 20 (that is, the vehicle 200). ) Send to nearby. The data here includes light reception position information indicating the current position of the electronic device 20 when the laser light is received by the laser light receiving unit 22 in SB01, and light reception time information indicating the time when the laser light is received. , Is included. In the present embodiment, LoRA is used as the specific low-power radio, so that data is directly transmitted to other electronic devices 30 and the like within a communication range having a radius of about 10 km centered on the vehicle 200. As described above, in the present embodiment, when laser light is received by the laser light receiving unit 22, data including light receiving position information and the like is automatically transmitted to the other electronic device 30 and the like by specific low power radio.

When executing SB02, the control unit 25 ends the specific low power transmission process of FIG.
On the other hand, when it is determined in SB01 that the laser light receiving unit 22 has not received the laser beam, the control unit 25 skips SB02 and ends the specific low power transmission process. That is, when it is determined that the laser beam is not received, the data is not transmitted to the other electronic device 30 or the like.

[2-3. Public line reception processing]
Next, public line reception processing executed by the control unit 35n of the electronic device 30 will be described with reference to the flowchart of FIG. The public line reception process is periodically executed while the electronic device 30 is powered on.

  First, at SC01, the control unit 35 determines whether a specified time has elapsed. Here, if the control unit 35 accesses the server 60 at least once after the power of the electronic device 30 is turned on and receives data including the light receiving position information, the control unit 35 defines the time from the last received time. Determine whether time has passed. That is, in the present embodiment, data reception is performed at regular time intervals (specified time). The specified time can be set by the user, and can be selected from, for example, 10 minutes, 30 minutes, 1 hour, and the like. If no data has been received from the server 60 at the time of execution of SC01, it is determined that the specified time has elapsed in SC01.

If the controller 35 determines in SC01 that the specified time has not elapsed, the controller 35 ends the public line reception process.
On the other hand, if the control unit 35 determines that the specified time has elapsed in SC01, the control unit 35 proceeds to SC02, designates a range, and receives data from the server 60 via the public line 70 by the wireless communication unit 23.

  The data here includes light reception position information and light reception time information transmitted from the electronic device 20 or the like mounted on another vehicle 200 to the public line 70. In the situation shown in FIG. 1, in SC02, the position information of the mobile orb 10 where the laser beam is received by the electronic device 20 or the like mounted on another vehicle 200 is received via the public line 70.

  In the present embodiment, the user can set the acquisition range of data acquired in SC01. That is, it is possible to receive only data in which the light receiving position is within a desired geographical range based on the current position of the electronic device 30 and the light receiving time is within a desired time range from the present time. In the present embodiment, the user can select a geographical range from a range of 100 km radius, 150 km range, or 200 km range centered on the current position of the electronic device 30. In addition, the user can select a time range from the current time within 24 hours, within one week, within one month, or all periods.

The control unit 35 uses the tethering function of the portable information terminal 50 to connect to the public line 70 and receives data from the server 60.
Subsequently, in SC03, the control unit 35 updates the internal data stored in the storage unit 26 based on the data received in SC02. Specifically, the received light position information (that is, the position information of the mobile orbit) within a predetermined range with the current position stored in the storage unit 36 as a reference and the received light time information are received from the received light position information in SC02. And the light reception time information is updated. When executing the control SC03, the control unit 35 ends the public line reception process of FIG.

[2-4. Specific low power reception processing]
Next, the specific low power reception process executed by the control unit 35 of the electronic device 30 will be described with reference to the flowchart of FIG. The specific low power reception process is repeatedly executed while the power of the electronic device 30 is on.

First, in SD01, the control unit 35 determines whether there is expired data in the internal data stored in the storage unit 36.
That is, since the mobile orbit moves, in this embodiment, the light reception position information and the light reception time information stored in the storage unit 36 (that is, the position information of the mobile orbit 10 and the time information when the laser beam is received). Has a valid time. Specifically, the remaining time obtained by subtracting the elapsed time from the time indicated by the light reception time information from the predetermined set time is set as the valid time. Then, it is determined that the data whose valid time has become zero is expired data. Note that the above-described set time (and hence valid time) can be set by the user, and is selected by the user from, for example, 24 hours, 1 week, 1 month, or all periods.

  If the control unit 35 determines in SD01 that the internal data has expired data, the control unit 35 proceeds to SD02 and deletes the expired data from the storage unit 26. The control unit 35 proceeds to SD03 when executing SD02.

On the other hand, if the control unit 35 determines in SD01 that there is no expired data in the internal data, it skips the above-described SD02 and proceeds to SD03.
Subsequently, in SD03, the control unit 35 starts receiving data by the specific low power radio.

  Subsequently, in SD04, the control unit 35 determines whether data is received from the electronic device 20 or the like mounted on the other vehicle 200 by the specific low power radio. The data here includes light reception position information and light reception time information transmitted from the electronic device 20 or the like mounted on another vehicle 200.

  When determining that the data is not received in SD04, the control unit 35 returns to SD01 described above. On the other hand, if the control unit 35 determines that data has been received in SD04, the control unit 35 proceeds to SD05.

  In SD05, the control unit 35 determines whether or not the internal data includes data in the vicinity of the position indicated by the light receiving position information received in SD04 (hereinafter referred to as “corresponding point”). That is, in SD05, it is determined whether or not the light receiving position information indicating the position (point) indicated by the light receiving position information received in SD04 is already stored in the storage unit 26.

  When the control unit 35 determines in SD05 that there is data near the corresponding point in the internal data, the control unit 35 proceeds to SD06 and updates the valid time of the corresponding point. That is, the control unit 35 replaces the valid time of the corresponding point with the valid time obtained by subtracting the elapsed time from the time indicated by the light reception time information received in SD04 from the set time. When executing SD06, the control unit 35 ends the specific low power reception process of FIG.

  On the other hand, if the control unit 35 determines in SD05 that there is no data in the vicinity of the corresponding point in the internal data, the control unit 35 proceeds to SD07, and displays the position indicated by the light reception position information received in SD04 and the time indicated by the light reception time information. The new point is stored in the storage unit 26.

When executing the control SD07, the control unit 35 ends the specific low power reception process of FIG.
[2-5. Alarm processing]
Next, alarm processing executed by the control unit 35 will be described with reference to the flowchart of FIG. The alarm process is repeatedly executed while the electronic device 30 is powered on.

First, in SE01, the control unit 35 acquires the current position of the electronic device 30 from the position detection unit 21, and updates the current position of the electronic device 30.
Subsequently, in SE02, the control unit 35 determines whether there is an alarm point within the specified range based on the updated current position of the electronic device 30 and the internal data stored in the storage unit 26.

  The specified range here is a specified range with the current position of the electronic device 30 as a reference. In this embodiment, the specified range is set to a range of several hundred meters in radius with the current position of the electronic device 30 as the center. This specified range includes a communication range in which data can be transmitted and received by a specific low-power radio, and a geographical acquisition range of data when acquiring data via the public line 70 (acquisition range of SB02 in FIG. 3), It is set narrower than any of the above. The specified range here can be set by the user.

  The alarm point is a position indicated by the light receiving position information stored in the storage unit 26. That is, in SE02, when the position indicated by the light receiving position information (in other words, the position of the mobile orbit) is included in the specified range based on the current position of the electronic device 30, the alarm point is included in the specified range. It is determined that there is.

When it is determined in SE02 that there is an alarm point within the specified range, the control unit 35 proceeds to SE03 and notifies the user that there is an alarm point within the specified range.
Specifically, the control unit 35 displays an alarm screen including the relative positional relationship and distance between the current position of the electronic device 30 and the alarm point on the display unit 24, thereby informing the user (alarm). ) When there are a plurality of alarm points within the specified range, a relative positional relationship with the plurality of alarm points is displayed.

The control unit 35 ends the alarm process of FIG. 6 when executing SE03.
On the other hand, when it is determined in SE02 that there is no alarm point within the specified range, the control unit 35 terminates the alarm processing in FIG. 6 without executing SE03 described above.

Therefore, even if the laser beam from the mobile orb 10 can be received only several tens of meters before the mobile orb 10, the electronic device 20 receives the laser beam and receives the received light position information via the public line 70. By transmitting to the device 30, the position information of the mobile orbit 10 can be received at a point where the electronic device 30 (and thus the vehicle 300) is far enough to reduce the speed sufficiently. Therefore, it is possible to notify the driver of the vehicle 300 in advance of the presence of the mobile orbit 10 using the laser beam, and to suppress the overspeed of the vehicle 300.

  Since the light receiving position information is received via the public line 70, the light receiving position information can be acquired anywhere in the country. That is, the light receiving position information can be received in a wider range than when the light receiving position information is received by the specific low power radio.

  Further, since the light receiving position information is transmitted to the server 60 via the public line 70, for example, dedicated application software is installed in the portable information terminals 40 and 50, and the light receiving position information ( As a result, the position information of the mobile orbit 10) can be confirmed. Therefore, user convenience can be improved.

  (2) In the present embodiment, the electronic devices 20 and 30 perform wireless communication of the Bluetooth standard or the Wi-Fi standard with the portable information terminal 40 that can be connected to the public line 70, and pass through the portable information terminals 40 and 50. Connect to the public line 70. Therefore, in order to connect to the public line 70, the user only has to make a contract with the communication company for the portable information terminals 40 and 50, and there is no need to make a separate contract for the electronic devices 20 and 30. Therefore, the communication cost can be reduced as compared with the configuration in which the electronic devices 20 and 30 are directly connected to the public line 70.

  In addition, the equipment for performing Bluetooth or Wi-Fi standard wireless communication is standardly installed in many existing portable information terminals, and is connected to the public line 70 using the equipment standardly installed in the existing portable information terminals. it can.

  (3) In the present embodiment, the electronic device 30 starts notification when there is an alarm point within a specified range based on the current position of the electronic device 30. In other words, the electronic device 30 performs notification on the condition that the distance between the current position of the electronic device 30 and the position indicated by the received light reception position information is within a certain distance.

Therefore, it can be notified to the driver that the mobile orbit 10 exists from a point away from the received light receiving position by a certain distance.
(4) In the present embodiment, the electronic device 30 includes a wireless communication unit 33 configured to communicate with an external device by a specific low-power radio, and other electronic devices existing in the communication range of the specific low-power radio. The light receiving position is directly transmitted and received via the apparatus 20 and the wireless communication unit 33. Then, the electronic device 30 performs notification based on the current position detected by the position detection unit 31 and the light receiving position indicated by the light receiving position information received by the wireless communication unit 33.

  Therefore, even when the other electronic device 20 cannot use the public line 70, the light receiving position information can be transmitted to and received from the other electronic device 20 by the specific low power radio. As a result, as compared with the configuration in which the light receiving position information is transmitted / received only through the public line 70, the driver can be notified in advance of the presence of the mobile orb 10 and the overspeed of the vehicle can be suppressed. Further, the light receiving position information can be transmitted / received to / from another electronic device 20 without necessarily making a contract for using the public line 70 with the communication company. In other words, communication costs can be reduced.

  In the present embodiment, the light receiving position information corresponds to the control position information, the wireless communication units 23 and 33 correspond to the public communication unit and the specific communication unit, the display units 24 and 34 correspond to the notification unit, and the portable information Terminals 40 and 50 correspond to communication devices. Further, SA02 corresponds to processing as a public transmission processing unit, SB02 corresponds to processing as a specific transmission processing unit, SC02 corresponds to processing as a public reception processing unit, and SD03 and SD04 serve as specific reception processing units. SE03 corresponds to the processing as the notification processing unit.

[4. Other Embodiments]
As mentioned above, although the form for implementing this indication was demonstrated, this indication is not limited to the above-mentioned embodiment, and can carry out various modifications.

  (1) In the above embodiment, the driver is notified by displaying an alarm screen on the display units 24 and 34, but the method of performing the notification is not limited to this. For example, a sound output unit that outputs sound may be mounted on the electronic devices 20 and 30 and the sound output unit may output the sound to notify the user. Further, for example, a notification may be given by mounting a light emitter such as an LED on the electronic devices 20 and 30 and causing the light emitter to emit light. In particular, notification may be performed using at least one of display, sound, and light. In addition, when notifying with a sound output part, a sound output part corresponds to an alerting | reporting part, and when alerting | reporting with a light-emitting body, a light-emitting body corresponds to an alerting | reporting part.

  (2) Although the portable information terminal is exemplified as the communication device in the above embodiment, the communication device is not limited to this. The communication device may be a wireless LAN access point other than the portable information terminal.

  (3) In the above embodiment, LoRA is exemplified as the standard for the specific low power radio. However, a standard for the specific low power radio other than LoRA may be used. As such a standard, for example, SIGFOX, Wi-Fi HaLow, Wi-SUN, RPMA, Flexnet, IM920, etc. may be used.

(4) In the above embodiment, the electronic devices 20 and 30 may be directly connected to the public line 70 without going through communication devices (such as the portable information terminals 40 and 50) that can be connected to the public line 70. In other words, the electronic devices 20 and 30 may be connected to the public line 70 without using the tethering function of the portable information terminals 40 and 50 or the like. According to such a configuration, the electronic devices 20 and 30 can be connected to the public line 70 without a communication device, and the light receiving position information and thus the control position information can be transmitted to and received from the server 60.
(5) In the above embodiment, when the laser light is received by the laser light receiving unit 22, the light receiving position information and the like are automatically transmitted from the electronic devices 20 and 30, but the transmission timing is not limited to this. For example, the light receiving position information and the like may be transmitted at a timing operated by the user. That is, the light receiving position information and the like may be transmitted manually.
(6) The server 60 executes a process for determining whether or not the internal data stored in the storage unit of the server 60 has expired data and a process of deleting the expired data stored in the storage unit May be. The data here is data including light reception position information and light reception time information. That is, processing corresponding to SD01 and SD02 in FIG. As a result, the server 60 stores only data whose effective time is not zero. Then, when the electronic devices 20 and 30 receive data from the server 60, the data whose valid time is not zero may be received.

(7) In the above embodiment, the light receiving position information or the like may be transmitted / received by only one of the public line 70 and the specific low power radio.
(8) In the above embodiment, the light receiving position information is exemplified as the control position information, but the control position information is not limited to this. For example, the control position information may be information indicating the position of the mobile orbit estimated based on the light receiving position. In this case, for example, based on the light receiving position, the direction in which the laser light has been irradiated, and the intensity of the laser light, the position of the mobile orvis that has been irradiated with the laser light may be estimated. Then, the control position information indicating the estimated position may be transmitted / received via the public line 70 or the specific low-power radio.

  (9) In the above-described embodiment, the reliability may be set for the light receiving position information transmitted to the public line 70, and thus the taking position information. For example, when the control position information indicating the same point is transmitted from a plurality of electronic devices to the server 60, it is considered that the mobile orvis 10 is likely to exist at that point. Therefore, for example, when the control position information indicating the same position is transmitted from the plurality of electronic devices 20 and 30 to the public line 70, the reliability may be set according to the number of transmissions. In this case, the control position information indicating the position where the number of times of transmission is large may be set with higher reliability. The electronic devices 20, 30, etc. may receive only the control position information whose reliability is a predetermined level or more via the public line 70.

  According to such a configuration, only the control position information indicating the position where the mobile orbit 10 is highly likely to be present, compared to the configuration in which the control position information is received from the public line 70 without setting the reliability. As a result, the reliability of the notification content notified by the display units 24 and 34 can be improved.

  (10) In the above-described embodiment, a specific low power wireless network may be formed by a plurality of electronic devices sequentially transmitting the light receiving position information, and thus the control position information, etc., by specific low power wireless. That is, for example, the electronic device 20 receives laser light from the mobile orbit 10 and transmits the control position information to the other electronic device 30 by specific low-power radio. Then, the electronic device 30 transmits the control position information received from the electronic device 20 to another electronic device (such as an electronic device positioned in a direction away from the electronic device 20) by specific low-power radio. By repeating this, a network with specific low-power radio may be formed. In other words, the electronic device directly transmits the control position information received from the other electronic device by the specific low power radio to an electronic device different from the other electronic device located in the communication range of the specific low power radio. May be.

According to such a configuration, the control position information can be transmitted to electronic devices within a wider range than the maximum propagation distance of the specific low-power radio.
(11) In the above embodiment, the alarm is started when the distance between the alarm point and the current position of the electronic devices 20 and 30 is within a certain distance, but the condition for starting the alarm is not limited to this. . For example, an alarm may be started when the distance is within a certain distance and the current positions of the electronic devices 20 and 30 are close to the position indicated by the control position information.

  Specifically, for example, in a two-dimensional space composed of latitude and longitude, the distance from the alarm point is about a specified distance, and the point (hereinafter referred to as “entry” on the road on which the vehicle 200 or the like is traveling or slightly deviated from the road. Point)). Then, traveling direction information is set along with the entry point. The traveling direction information is information indicating the traveling direction of the vehicle when the vehicle equipped with the electronic device passes through the entry point and enters the specified range. The position information and travel direction information of the entry point are set manually or automatically in advance. The set data may be stored in advance in the storage unit 26 or may be received from the external server 60 or the like. Then, the notification may be started when the vehicle 200 or the like passes the entry point in the traveling direction specified by the traveling direction information.

  In other words, the electronic devices 20 and 30 each include the position information of a plurality of entry points set in the vicinity of the boundary between the inside and the outside of the specified range based on the position indicated by the received enforcement position information, The travel direction information that is set for each of the entry points and indicates the travel direction when the vehicle 200, 300 travels the entry point when the vehicle 200 or 300 approaches the position indicated by the received control position information is acquired. Then, the electronic devices 20 and 30 are based on the acquired position information and travel direction information of the entry point, and the vehicle 200 and 300 have travel direction information in which one of the plurality of entry points is set as the entry point. Notification is started when the vehicle passes in the traveling direction specified by.

  Even if the distance between the current position of the electronic devices 20 and 30 and the position indicated by the enforcement position information is within a certain distance, the vehicle 200 or 300 on which the electronic devices 20 and 30 are mounted is the position indicated by the enforcement position information, and hence the movement. When it does not approach the formula Orbis 10, there is little need for notification. According to the above configuration, when the distance is within a certain distance and the current positions of the electronic devices 20 and 30 are close to the position indicated by the control position information, in other words, there is a need to perform notification.
