  DESCRIPTION OF EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. The embodiments described below do not unduly limit the contents of the present invention described in the claims. Also, not all of the configurations described below are essential constituent requirements of the present invention.

1. Collision hazard notification system 1-1. Overview of Collision Risk Notification System FIG. 1 is a diagram illustrating an overview of a collision risk notification system. Here, a case where a collision danger notification system (hereinafter simply referred to as “system”) is applied to a paraglider (an example of sports) will be described as an example.

  As shown in FIG. 1, the system of this embodiment includes a management terminal 1A (an example of a server) and a sports user terminal 1C (an example of a notification device).

The management terminal 1A is, for example, an information terminal fixed at the start point S of the paraglider flight area. When the gate SG installed by the operator of the flight area is installed at the start point S, the management terminal 1A may be configured as a part of the gate SG or may be installed independently of the gate SG. Good. It is desirable that at least the management terminal 1A be installed near a point where a paraglider pilot (flyer) always passes. For example, the location of the management terminal 1A can be set to accept a flight area. In addition, a flight area is an area on the ground (including the surface of water) of about 60000 m ² with ups and downs, and in the following, when the flight area is referred to, it means flying over the flight area. To do.

  The user terminal 1C is a plurality of portable information terminals that are individually carried by a plurality of flyers (hereinafter referred to as “user 2”) that use the flight area. Each of the plurality of users 2 is a user registered in advance with respect to the management terminal 1A as a user of the system of the present embodiment. In the example shown in FIG. 1, the user terminal 1 </ b> C is fixed to a paraglider equipment (for example, a harness 2 </ b> A worn by the user 2) in an appropriate posture at a position where the user 2 can see during the flight. Such a user terminal 1C is configured as, for example, a tablet PC (PC: personal computer).

In the above system, each of the management terminal 1A and the plurality of user terminals 1C can be connected to the global network (reference numeral 1D in FIG. 2) via, for example, a mobile phone network. When connected to the network 1D, the management terminal 1A and each of the plurality of user terminals 1C can communicate with each other via the network 1D.

  Further, when the distance between the user terminals 1C is less than a certain distance, for example, Bluetooth (registered trademark) (including BTLE: Bluetooth Low Energy), Wi-Fi (registered trademark) (Wi-Fi: Wireless Fidelity) It is also possible to communicate directly by short-range wireless communication such as For example, among a plurality of user terminals 1C existing in the flight area, user terminals 1C whose distances are equal to or less than a certain distance can directly communicate with each other by short-range wireless communication. The distance that the user terminals 1C can directly communicate with each other is, for example, about 600 m (it is desirable that at least 100 m is ensured for the communicable distance).

  Note that the communication standard used when the management terminal 1A and the plurality of user terminals 1C communicate via the network 1D is different from the communication standard used when the user terminals 1C communicate directly with each other. It doesn't matter, but it doesn't matter. In addition, indirect communication via the network 1D can be used instead of direct communication between the user terminals 1C. In this case, the user terminals 1C that can communicate with each other have a flight area. It is preferable to limit the user terminals 1C of the user 2 that are used at the same time (see “Communication via a network” described later). Hereinafter, it is assumed that direct communication is used for communication between the user terminals 1C. The maximum distance at which direct communication is possible is, for example, 100 m to 1000 m, and is assumed to be 1000 m hereinafter.

  The management terminal 1A is equipped with a function for monitoring the positions of a plurality of user terminals 1C existing in the flight area and a function as a server for distributing information to the plurality of user terminals 1C existing in the flight area. The

1-2. Outline of User Operation Hereinafter, an outline of the operation of the user 2 will be described.

  In advance, the user 2 inputs his / her registration data to his / her user terminal 1 </ b> C at home, for example. This input is performed via the operation unit (reference numeral 150 in FIG. 2) of the user terminal 1C. The registration data includes information such as the user name (user ID) of the user 2, the type of license held by the user 2 for the paraglider, and the number of flights of the paraglider. The registration data input by the user 2 to the user terminal 1C is written to the storage unit (reference numeral 130 in FIG. 2) of the user terminal 1C.

  On the day of the flight, the user 2 wears a paraglider and attaches the user terminal 1C to the harness 2A or the like. When the user 2 reaches the vicinity of the start point S in the flight area, the user 2 inputs a connection instruction to the network 1D and a registration instruction to the user terminal 1C via the operation unit 150 of the user terminal 1C. The user terminal 1C connects to the network 1D to access the management terminal 1A, and the registration data stored in the storage unit 130 of the user terminal 1C and the terminal ID of the user terminal 1C are sent to the management terminal 1A in a predetermined format.

  Here, when the registration of the user terminal 1C with the management terminal 1A (the registration of the user 2) is completed, the user terminal 1C may collide with other users when the user 2 of the user terminal 1C flies in the flight area. It becomes possible to notify the user 2 of the presence or absence. The “other users” here are users of other user terminals (other devices) that have been registered for the management terminal 1A and are present in the vicinity of the flight area at the same time. is there.

  When the registration of the user terminal 1C to the management terminal 1A (including the registration of the user 2) is completed, the user terminal 1C receives provision (notification) of data related to the flight area from the management terminal 1A via the network 1D. It becomes possible. When the user 2 of the user terminal 1C flies through the flight area, the user terminal 1C displays information related to the flight area (area data) on the display unit (reference numeral 170 in FIG. 2) of the user terminal 1C. Details of the area data will be described later.

  Next, the user 2 inputs a start instruction to the user terminal 1C via the operation unit 150 of the user terminal 1C. Thereafter, the user 2 passes the start point S in the flight area, starts running on a downhill provided in the flight area, and takes off at an appropriate timing. Thereby, the flight of the user 2 is started.

  When the user terminal 1C automatically starts operation when the user terminal 1C enters the flight area, the user 2 can omit the input of the start instruction ("automatic start / end" described later). reference).

  During the flight, the user 2 can display area data (see FIG. 9 described later) on the display unit 170 of the user terminal 1C by inputting an area data display instruction to the user terminal 1C as necessary. . The display instruction by the user 2 is given via the operation unit 150 of the user terminal 1C. The area data (FIG. 9) includes various types of information for the user 2 to perform a flight comfortably or happily.

  During the flight, the user terminal 1C communicates directly with the other user terminal 1C and executes an alert process described later. When it is determined by the alert process that there is a risk of collision, the user terminal 1C notifies the user 2 of the risk.

  The user terminal 1C basically notifies the user 2 of the danger on the display unit 170 of the user terminal 1C (see FIG. 8 described later). In addition, when danger arises during the display of the area data (FIG. 9) mentioned above, the user terminal 1C interrupts the display of area data (FIG. 9), and gives priority to the notice of danger (FIG. 8). Shall. By this notification, the user 2 can take an appropriate avoidance action.

  Thereafter, the user 2 lands at an appropriate point in the flight area and moves outside the flight area. When ending the flight, the user 2 inputs an end instruction to the user terminal 1C via the operation unit 150 of the user terminal 1C, and when continuing the flight, the user 2 does not input the end instruction, Return to S and take off again. When the user 2 inputs an end instruction to the user terminal 1C, the process related to the display of the area data (FIG. 9) and the danger notification (FIG. 8) by the user terminal 1C is ended.

  In addition, when the user terminal 1C automatically ends the operation when the user terminal 1C leaves the flight area, the user 2 can omit the input of the end instruction ("start / end automation" described later). reference).

  The climate data 130C in the storage unit 130 of the management terminal 1A includes information such as cloud thickness distribution, atmospheric pressure distribution, and wind speed vector distribution on the day of the flight area downloaded from the weather server. However, in this embodiment, each user terminal 1C includes its own barometric pressure data in the sensing data and uploads it to the management terminal 1A via the network 1D at an appropriate timing (for example, periodically). Can also hold the approximate atmospheric pressure distribution of the flight area as the climate data 130C.

The alert process according to the present embodiment includes a first approach determination that determines whether or not there is a relatively low risk and a second approach determination that determines whether or not there is a relatively high risk. Hereinafter, the first approach determination and the second approach determination will be described in order. Here, focusing on a certain user terminal 1C, the focused user terminal 1C is referred to as “own device”, and the other user terminal 1C not focused on is referred to as “other device”. The own device is an example of a first portable terminal and is an example of a notification device configured integrally with the first portable terminal, and the other device is an example of a second portable terminal.

1-5-1. First Approach Determination First, the processing unit 120 of the own device establishes communication (short-range wireless communication) with the processing unit 120 via the communication unit 190 of the own device and the communication unit 190 of the other device. In the present embodiment, it is assumed that communication (short-range wireless communication) is not established with another device whose distance from the own device is a certain distance or more.

The own position data (latitude, longitude, altitude) and speed data (speed vector) are position data and speed data included in the latest positioning data acquired by the own GPS sensor 110 (position data of the own apparatus). And the velocity data is an example of first information related to the current position and the current velocity vector.).

In addition, the processing unit 120 of the own device receives the position data (latitude, longitude, altitude, and speed data (speed vector) of the other device from the processing unit 120 of the other device. The position data (latitude, longitude, altitude of the other device). ) And speed data (speed vector) are position data and speed data included in the latest positioning data acquired by the GPS sensor 110 of the other machine (the position data and speed data of the other machine are the current position and current data). An example of the second information related to the velocity vector.)

  Next, the processing unit 120 of the own device includes the position coordinates (latitude, longitude, altitude) of the other device, the speed vector of the other device, the position coordinates (latitude, longitude, altitude) of the own device, and the speed of the own device. Based on the vector, whether or not another device can exist (approach) within the first predetermined distance range (here, within 600 m) within the first predetermined time (here, within 10 seconds). Determine.

  Specifically, as shown in FIG. 4, the processing unit 120 of the own machine calculates the predicted trajectory Q1 of the own machine based on the position coordinates of the own machine and the speed vector of the own machine, and the position coordinates of the other machine and the other The predicted trajectory Q2 of the other machine is calculated based on the speed vector of the machine. The horizontal axis in FIG. 4 indicates the elapsed time t from the current time point, and the vertical axis in FIG. 4 is the position coordinates (latitude, longitude, altitude). However, in FIG. 4, three-dimensional position coordinates are represented in one dimension.

  Next, as shown in FIG. 4, the processing unit 120 of the own device sets a warning range centered on the expected trajectory Q1 at each time of the own device and having a radius of the first predetermined distance Thp (= 600 m). To do. Then, the processing unit 120 of the own device calculates a grace time t1 from the current time until the time when the predicted trajectory Q2 of the other device first enters the alert range.

  Further, the processing unit 120 of the own device compares the grace time t1 with the first predetermined time Tht (= 10 seconds), and when the grace time t1 is smaller than the first predetermined time Tht (= 10 seconds). It is determined that the other aircraft approaches within the first predetermined distance range (within 600 m) within the first predetermined time (within 10 seconds), and otherwise, within the first predetermined time (within 10 seconds). It is determined that the other aircraft does not approach within the first predetermined distance range (within 600 m).

  In the example shown in FIG. 4, a case where another machine approaches within the first predetermined distance range (within 600 m) within the first predetermined time (within 10 seconds) (t1 <Tht) is shown.

1-5-2. Second Approach Determination First, the processing unit 120 of the own device establishes communication (short-range wireless communication) with the processing unit 120 via the communication unit 190 of the own device and the communication unit 190 of the other device. In the present embodiment, it is assumed that communication (short-range wireless communication) is not established with another device whose distance from the own device is a certain distance or more.

  Next, the processing unit 120 of the own device transmits the position data (latitude, longitude, altitude) and speed data (speed vector) of the own device to the processing unit 120 of the other device. The own position data (latitude, longitude, altitude) and speed data (speed vector) are position data and speed data included in the latest positioning data acquired by the own GPS sensor 110 (position data of the own apparatus). And the velocity data is an example of first information or second information related to the current position and the current velocity vector.).

  The processing unit 120 of the own device receives position data (latitude, longitude, altitude) and speed data (speed vector) of the other device from the processing unit 120 of the other device. The position data (latitude, longitude, altitude) and speed data (speed vector) of the other machine are position data and speed data included in the latest positioning data acquired by the GPS sensor 110 of the other machine (position data of the other machine). And the velocity data is an example of first information or second information related to the current position and the current velocity vector.).

Next, the processing unit 120 of the own device includes the position coordinates (latitude, longitude, altitude) of the other device, the speed vector of the other device, the position coordinates (latitude, longitude, altitude) of the own device, and the speed of the own device. Based on the vector, whether or not another aircraft can exist (approach) within the second predetermined distance range (here, within 200 m) within the second predetermined time (here, within 5 seconds). Determine.

  Specifically, as shown in FIG. 5, the processing unit 120 of the own device calculates the predicted trajectory Q1 of the own device based on the position coordinates of the own device and the velocity vector of the own device, The predicted trajectory Q2 of the other machine is calculated based on the speed vector of the machine. The horizontal axis in FIG. 5 indicates the elapsed time t from the current time point, and the vertical axis in FIG. 5 is the position coordinates (latitude, longitude, altitude). However, in FIG. 5, three-dimensional position coordinates are represented in one dimension.

  Next, as shown in FIG. 5, the processing unit 120 of the own device has a warning range centered on the expected trajectory Q1 at each time of the own device and having a radius of the second predetermined distance Thp ′ (= 200 m). Set. Then, the processing unit 120 of the own device calculates a grace time t1 'from the current time until the time when the predicted trajectory Q2 of the other device first enters the alert range.

  Further, the processing unit 120 of the own device compares the grace time t1 ′ with the second predetermined time Tht ′ (= 5 seconds), and the grace time t1 is smaller than the second predetermined time Tht ′ (= 5 seconds). In this case, it is determined that the other aircraft approaches within the second predetermined distance range (within 200 m) within the second predetermined time (within 5 seconds), and otherwise, within the second predetermined time (5 Within 2 seconds), it is determined that the other aircraft does not approach within the second predetermined distance range (within 200 m).

  In the example shown in FIG. 5, a case where another machine approaches within the second predetermined distance range (within 200 m) within the second predetermined time (within 5 seconds) (t1 ′ <Tht ′) is shown.

1-5-3. Comprehensive determination based on the first approach determination and the second approach determination Here, the examples shown in FIGS. 6 and 7 have a lower risk of contact with the other apparatus than the examples shown in FIGS. It is an example.

  “Low risk” here means that the distance between the aircraft and the other aircraft is large, and the relative speed between the aircraft and the other aircraft is low, so the possibility that they are in contact with each other is low. “High risk” means that the distance between the own machine and the other machine is small, and the relative speed between the own machine and the other machine is high, so that there is a high possibility that the two will come into contact with each other.

  In the examples shown in FIGS. 6 and 7, the risk that the own machine will come into contact with other machines is lower than the examples shown in FIGS. 4 and 5, so the first approach determination (FIG. 6) determines “approach”. However, in the second approach determination (FIG. 7), it is determined that “do not approach” (t1 ′> Tht ′).

  Although not shown in the drawings, when the degree of risk that the own device is in contact with another device is lower than the example shown in FIGS. 6 and 7, it is determined that the vehicle does not approach in the first approach determination (t1>). Tht), it is determined that “not approaching” in the second approach determination (t1 ′> Tht ′).

  Therefore, if the above first approach determination and second approach determination are combined, the risk of the own aircraft coming into contact with other aircraft is evaluated in the following three stages: “medium”, “high”, and “low” can do.

(1) High risk level
When it is determined as “approaching” in the first approach determination and “approaching” in the second approach determination (corresponding to the example of FIGS. 4 and 5).

(2) Medium risk
In the first approach determination, it is determined as “approaching”, but in the second approach determination, it is determined as “not approaching” (corresponding to the example of FIGS. 6 and 7).

(3) Low risk
A case where it is determined that “does not approach” in the first approach determination and a case where it is determined that “not approach” is determined in the second approach determination (not shown). When it is determined that “not approaching” in the first approach determination, the second approach determination can be omitted because it should be determined as “not approaching” in the second approach determination (FIG. 10). (See S53N).

1-6. Notification Process by User Terminal FIG. 8 is an example of a screen for notifying danger.

  If the processing unit 120 of the own device determines that it is “approaching” by the first approach determination or the second approach determination, the processing unit 120 displays a screen for notifying the user 2 of the own device of the danger to the display unit 170 of the own device. indicate. On this screen (notification screen), for example, as shown in FIG. 8, an arrow mark m1 representing the speed vector of the own device and an arrow mark m2 representing the speed vector of the other device determined to approach are arranged.

  Also, a text image m1 ′ (for example, a text image of “you”) indicating the user ID of the user 2 of the own device is assigned to the arrow mark m1 indicating the speed vector of the own device, and an arrow indicating the speed vector of the other device. A text image m2 ′ (for example, a text image “Mr. A”) indicating the user ID of the user of the other device is assigned to the mark m2.

  The arrow mark m2 representing the speed vector of the other machine has a text image m2 ′ (for example, “Mr. A”) indicating the user ID (an example of user information) and the type of license (user) A text image m2 ″ (for example, “Class A”) indicating an example of information, an example of proficiency of sports, and an example of license information of sky sports) is given.

  Therefore, the user 2 of the own device can accurately determine the action to be taken for avoiding the collision according to the type and level of the user of the other device.

  Further, a mark M1 indicating the degree of danger is arranged on the notification screen. Since it is desirable that the mark M1 is emphasized, for example, an emphasis color (for example, yellow) that is considered to represent danger may be given, and the display color (luminance, color, saturation, etc.) of the mark M1 may be given. It may be changed over time.

  Furthermore, the processing unit 120 of the own device may change the display mode of the mark M1 depending on whether the degree of risk is “medium” or “high”. Specifically, the mark M may be emphasized when the degree of risk is “high” rather than “medium”.

  For example, the processing unit 120 of the own machine may make the size of the mark M1 when the risk is “high” larger than the size of the mark M1 when the risk is “medium”.

  In addition, the processing unit 120 of the own machine may set the time change cycle of the mark M1 when the risk is “high” to be narrower than the time change cycle of the mark M1 when the risk is “medium”. Good.

  In addition to displaying the mark M1 on the notification screen or instead of displaying the mark M1 on the notification screen, the processing unit 120 of the own device may change the overall color (luminance, color, saturation), etc. of the notification screen over time. .

In addition to the image display on the display unit 170 or instead of the image display on the display unit 170, the processing unit 120 of the own device outputs a sound (alarm Sound) may be used.

  Accordingly, the user 2 of his / her own device distinguishes whether a relatively high risk is approaching or a relatively low risk is approaching based on the enhancement degree of the notification screen displayed on the display unit 170. Can do.

  Since it is highly necessary for the user 2 to hear the wind sound with the ear during the paraglider flight, it is basically desirable to use an image rather than an alarm sound for danger notification. However, if an intermittent alarm sound is used instead of a steady alarm sound, it is considered that the user 2 can hear both the wind sound and the alarm sound.

  Further, the processing unit 120 of the own device communicates with the processing unit 120 of the management terminal 1A at an appropriate timing (for example, periodically) via the communication unit 190 of the own device, the network 1D, and the communication unit 190 of the management terminal 1A. (See symbol S75 in FIG. 11), user registration data 130A, sensing data 130B, and climate data 130C are received and written (or updated) in the storage unit 130 of the own device. Accordingly, the processing unit 120 of the own device, upon the first approach determination or the second approach determination described above, uses the terminal ID of the other device and the user registration data 130A written in the storage unit 130 of the own device. Based on this, it is possible to recognize the user ID of the user of the other machine and the type of license held by the user of the other machine.

1-7. Display processing of area data by user terminal FIG. 9 is an example of a display screen of area data.

  The processing unit 120 of the own device displays the area data on the display unit 170 of the own device in response to the display instruction of the area data from the user 2. On this screen (display screen), for example, as shown in FIG. 9, data relating to the user 2 of the own aircraft and data relating to users of one or more other aircraft present in the flight area are displayed simultaneously.

  The data related to the user 2 of the own device is, for example, a curved image m3 representing the movement locus of the user 2 of the own device up to the present time.

  The data related to the user of the other device is, for example, a curved image m4 representing the movement trajectory of the user of the other device up to the present time.

  Further, a text image m1 ′ (for example, “you”) indicating the user ID of the user 2 of the own device is given to the curve image m3 representing the movement locus of the own device, and the curve image m4 representing the movement locus of the other device is added. Is given a text image m2 ′ (for example, “Mr. A”) indicating the user ID of the user of the other device.

  The curved image m4 representing the movement trajectory of the other device includes a text image m2 ′ (for example, “Mr. A”) indicating the user ID and a text image m2 ″ (for example, indicating the type of license held by the user of the other device "Class A" and "Tandem").

  Accordingly, the user 2 of the own aircraft can confirm the positional relationship of the user 2 of the other aircraft in the flight area, and can grasp, for example, what level the user is flying on which route.

In addition, the user 2 of the own device can also estimate the state of the airflow in the flight area based on the shape (movement pattern) of one or a plurality of users' movement trajectories in the flight area. For example, when the movement trajectory of the user of one or a plurality of other aircraft draws a spiral trajectory in the partial area of the flight area (see the movement trajectory of Mr. E in FIG. 9), the user 2 of the own aircraft It can also be estimated that the updraft is generated in the partial area.

  In addition to the curved image representing the movement trajectory, the display screen may display an image representing the climate data (cloud thickness distribution, atmospheric pressure distribution, wind speed vector distribution, etc.) in the flight area.

  The processing unit 120 of the own device communicates with the processing unit 120 of the management terminal 1A at an appropriate timing (for example, periodically) via the communication unit 190 of the own device, the network 1D, and the communication unit 190 of the management terminal 1A. (See symbol S75 in FIG. 11), receives user registration data 130A, sensing data 130B for each registered user, and flight area climate data 130C, and writes (or updates) the data to the storage unit 130 of the own aircraft. To do. Accordingly, the processing unit 120 of the own device is based on the latest user registration data 130A written in the storage unit 130 of the own device when the area data display instruction is input, so that the user ID of the user of the other device is obtained. And the types of licenses held by other users. In addition, when the area data display instruction is input, the processing unit 120 of the own aircraft is based on the latest climate data 130C written in the storage unit 130 of the own aircraft, so that the cloud thickness distribution in the flight area is obtained. , Atmospheric pressure distribution, wind speed vector distribution, etc. can be recognized.

  FIG. 9 shows an example in which the movement trajectory viewed from above is displayed on the display screen. However, since the movement trajectory is three-dimensional data, the processing unit 120 of the own device sets the viewpoint of the display screen to the user 2. May be changed freely. An instruction to change the viewpoint by the user 2 is issued via the operation unit 150 of the own device.

  In addition, FIG. 9 shows an example in which the movement trajectory up to the present time is displayed as a curve, but the processing unit 120 of the own machine displays an animation in which the movement trajectory is extended according to time (elapsed time of position). You may display on the display part 170. FIG.

1-8. Flow of Alert Process by User Terminal FIG. 10 is an example of a flow of alert process of the user terminal. Hereinafter, the steps of FIG. 10 will be described in order.

  First, the processing unit 120 of the own device waits until a start instruction is input from the user 2 via the operation unit 150 of the own device (S41N).

  Next, when a start instruction is input from the user 2 (S41Y), the processing unit 120 of the own device starts positioning of the own device by driving the GPS sensor 110 of the own device (S43). In addition, positioning is performed regularly (for example, every 1/30 second), for example.

  Next, the processing unit 120 of the own device determines whether or not there is another device capable of short-range wireless communication via the communication unit 190 of the own device (S45). (S45Y), communication is established with the processing unit 120 of the other device, and the first approach determination (S47) is executed. If there is not (S45N), the end determination (S67) is executed.

  When it is determined by the first approach determination (S47) that the other device is “approaching” (S53Y), the processing unit 120 of the own device notifies the user 2 of the own device of the danger (S55), otherwise ( In step S53N, the second approach determination (S57) is skipped and an end determination (S67) is executed.

After notifying the danger (S55), the processing unit 120 of the own machine executes the second approach determination (S57).

  When it is determined by the second approach determination (S57) that the other device is “approaching” (S63Y), the processing unit 120 of the own device notifies the user 2 of the own device of the danger (S65), otherwise ( In step S63N, the notification (S65) is skipped and an end determination (S67) is executed.

  In the end determination (S67), the processing unit 120 of the own device determines whether or not the end instruction of the user 2 is input via the operation unit 150.

  If the end instruction is not input (S67N), the processing unit 120 of the own device returns to the search process (S45) of the communicable user terminal 1C, and if the end instruction is input (S67Y), the processing unit 120 of the own device. Ends the flow.

1-9. Flow of Area Data Display Processing by User Terminal FIG. 11 is an example of a flow of area data display processing by the user terminal. This display process is executed in parallel with the alert process (FIG. 10) described above, for example.

  First, the processing unit 120 of the own device waits until a start instruction is input from the user 2 via the operation unit 150 (S71N).

  Next, when a start instruction is input from the user 2 (S71Y), the processing unit 120 of the own device accesses the management terminal 1A via the network 1D (transmits an access request) and is generated by the own device. The latest sensing data (position data, speed data, barometric pressure data, etc.) with the terminal ID of its own device is uploaded to the management terminal 1A (S73).

  Next, the processing unit 120 of the own device downloads the latest user registration data 130A, the latest sensing data 130B, and the latest climate data 130C from the management terminal 1A via the network 1D (S75). The processing unit 120 of the own device writes the downloaded user registration data 130A, sensing data 130B, and climate data 130C in the storage unit 130 of the own device. When the user registration data 130A, sensing data 130B, and climate data 130C already exist in the storage unit 130 at the time of writing, the processing unit 120 of the self-machine will register the user registration data 130A, sensing data 130B, The climate data 130C is updated.

  Next, the processing unit 120 of the own device determines whether or not an area data display instruction is input from the user 2 of the own device (S77). If the display instruction is input (S77Y), the display processing is performed. The process proceeds to (S79), and if not (S77N), the process proceeds to an end determination process (S81).

  In the display process (S79), the processing unit 120 of the own device displays a display screen (FIG. 9) based on the latest user registration data 130A, sensing data 130B, and flight area climate data 130C stored in the storage unit 130 of the own device. ) Is created and displayed on the display unit 170, and the process proceeds to the end determination process (S81).

  In the end determination process (S81), the processing unit 120 of the own device determines whether or not the end instruction of the user 2 is input via the operation unit 150.

  When the end instruction is not input (S81N), the processing unit 120 of the own device returns to the upload processing (S73), and when the end instruction is input (S81Y), the processing unit 120 of the own device ends the flow. .

1-10. Process Flow of Management Terminal FIG. 12 is an example of the process flow of the management terminal (server).

  First, the processing unit 120 of the management terminal 1A waits until a start instruction is input from the operator via the operation unit 150 of the management terminal 1A (S101N).

  Next, when a start instruction is input from the operator (S101Y), the processing unit 120 of the management terminal 1A starts an access determination process (S103).

  In the access determination process (S103), the processing unit 120 of the management terminal 1A determines whether an access request is received from any user terminal 1C via the network 1D.

  When the access request is received (S103Y), the processing unit 120 of the management terminal 1A shifts to the sensing data reception process (S105), and otherwise (S103N) shifts to the end determination process (S109).

  In the sensing data reception process (S105), the processing unit 120 of the management terminal 1A receives the sensing data from the user terminal 1C that is the transmission source of the access request via the network 1D, and receives the received sensing data of the management terminal 1A. Accumulate in the storage unit 130. Thereby, the sensing data 130B of the storage unit 130 is updated. In the sensing data 130B, sensing data received by the management terminal 1A from the user terminal 1C so far is stored in time series for each terminal ID (for each registered user).

  Next, the processing unit 120 of the management terminal 1A receives the latest user registration data 130A, the latest sensing data 130B, and the latest climate data 130C stored in the storage unit 130 of the management terminal 1A via the network 1D. The data is transmitted to the user terminal 1C (S107), and the end determination process (S109) is started.

  Note that the processing unit 120 of the management terminal 1A in step S107 identifies the user terminal 1C that exists outside the flight area based on the latest position coordinates included in the sensing data 130B, and the user terminal 1C that exists outside the flight area. May be excluded from transmission targets. In this way, data to be transmitted to the user terminal 1C can be reduced. In addition, the processing unit 120 of the management terminal 1A may minimize the amount of data transmitted to the user terminal 1C by excluding data unnecessary for display of area data from the transmission target. .

  In the termination determination process (S109), the processing unit 120 of the management terminal 1A determines whether or not an operator termination instruction has been input via the operation unit 150.

  When the termination instruction is not input (S109N), the processing unit 120 of the management terminal 1A returns to the access determination process (S103). When the termination instruction is input (S109Y), the processing unit 120 of the management terminal 1A performs the flow. finish.

1-11. As described above, the user terminal 1C according to the present embodiment includes the first information related to the current position of the own device and the current speed vector of the own device, the current position of the other device, and the like. Using the second information related to the current speed vector of the aircraft, it is determined whether or not the own aircraft and the other aircraft approach within a predetermined distance range within a predetermined time (S47 in FIG. 10). When it is determined that the aircraft and the other aircraft are approaching within a predetermined distance range within a predetermined time (S53Y in FIG. 10), the user 2 is notified of the approach (S55 in FIG. 10).

  That is, the processing unit 120 of the user terminal 1C relates to the first information related to the current position of the own device and the current speed vector of the own device, and the current position of the other device and the current speed vector of the other device. Using the second information to determine whether or not the own device and the other device approach within a predetermined distance range (within 600 m) within a predetermined time (within 10 seconds), and display unit 170 (and sound) When the output unit 180) determines that the own device and the other device approach within a predetermined distance range (within 600 m) within a predetermined time (within 10 seconds), the output unit 180) notifies the user 2 of the own device that they are approaching. To do. Therefore, the display unit 170 (and the sound output unit 180) is configured so that the distance between the own device and the other device approaches within a predetermined distance range (within 600 m) and the own device and the other device within a predetermined time (10 If at least one of the time conditions of approaching (within seconds) is not satisfied, no notification is made. Accordingly, the user terminal 1C is less likely to cause excessive and insufficient notification than the notification device that always notifies when either the distance condition or the time condition is satisfied, and thus improves the comfort and safety of the user. be able to. Therefore, according to the present system, it is possible to improve the reliability of notification to the user 2 and to prompt the user 2 to perform a certain avoidance action.

2. Modification 2-1. Start / End Automation The user terminal 1C according to the above-described embodiment starts the operation in response to the input of the start instruction by the user 2, and ends the operation in response to the input of the end instruction by the user 2. And at least one of the termination may be automatically performed.

  For example, the processing unit 120 of the user terminal 1 </ b> C includes the position coordinates (latitude and longitude) included in the latest positioning data of the own device, and the position coordinates of the flight area (latitude and latitude of the outline of the area) stored in advance by the own device. Based on the (longitude), whether or not the position coordinate of the aircraft is within the flight area, and the operation starts when the position coordinates of the aircraft move from outside the flight area into the flight area. The operation may be terminated at the timing when the position coordinate of the position moves from the flight area to the outside of the flight area.

2-2.
