Since the output device 3006 and the bus connecting them are the same in terms of hardware, description thereof is omitted.

  FIG. 5 is a diagram showing an example of the functional configuration of the flight monitoring system 1. In the air vehicle 10, the detection unit 11 detects an abnormality from the state of the air vehicle 10 such that the air vehicle 10 may fall, generates abnormal information indicating the content of the abnormality, and detects the abnormality. 2 to the server device 20. The abnormality referred to here includes, for example, a case where an abnormal value is detected by various sensor groups included in the sensor 1008 and a case where the positioning result by the positioning device 1009 deviates from the planned flight route by a predetermined value or more. The air vehicle 10 preliminarily specifies a range (threshold value) that is likely to fall as an abnormal value range (threshold value) of the sensor 1008 and a deviation range (threshold value) of the positioning result by the positioning device 1009 by experiment or simulation. I remember what was done. The abnormality information transmitted from the flying object 10 to the server device 20 via the network 2 includes the detection values by the various sensor groups included in the sensor 1008 and the positioning result by the positioning device 1009.

  In the server device 20, the acquisition unit 21 acquires the abnormality information generated by the detection unit 11 of the aircraft 10 via the network 2.

  In the server device 20, when the acquisition unit 21 acquires the abnormality information, the estimation unit 22 estimates the range of the ground on which the aircraft 10 falls (referred to as the fall range). More specifically, the estimation unit 22 estimates the falling range of the flying body 10 based on the flight state of the flying body 10. The flight state here includes the flight speed (including acceleration) of the flying object 10, the flight direction, the flight altitude, etc. calculated from the detection value of the sensor 1008 and the positioning result by the positioning device 1009. If these flight speeds, flight directions, and flight altitudes are known, the range of the ground on which there is a possibility of falling and the time of its falling are calculated by the equation of motion when the flying body 10 begins to drop at the time of the abnormality detection. It is possible to In addition, the estimation unit 22 acquires weather information (especially wind direction and air volume) at the flight point of the flying body 10 from a weather information database (not shown), and uses this to estimate the fall range and fall time of the flying body 10. Good.

  In the server device 20, the transmission control unit 23 identifies the user terminal 30 corresponding to the fall range estimated by the estimation unit 22 as the transmission destination, and provides the identified user terminal 30 with the fall information regarding the fall of the air vehicle 10. Send. More specifically, the transmission control unit 23 specifies one or more base stations 3 that include the range estimated by the estimation unit 22 in a wireless communication range (so-called cell), and sets the wireless communication range of the specified base station 3 in the specified range. The fall information is transmitted with the user terminal 30 in the area being the destination. For this reason, the transmission control unit 23 indicates so-called in-zone information indicating which base station 3 the wireless communication range of the user terminal 30 is in (in-zone) and the position of the wireless communication range of each base station 3. The cell position information is acquired from a predetermined storage device such as a home location register connected to the network 2. Alternatively, the transmission control unit 23 may periodically acquire and store these in-zone information and cell position information. The fall information transmitted to the user terminal 30 is information for informing the user that the flying body 10 may fall, and includes, for example, at least one of characters, images, sound, vibration, or light. It includes information to be output from the user terminal 30.

[motion]
Next, the operation of this embodiment will be described. In the following description, when the server device 20 is described as a main body of processing, specifically, the processor 2001, the memory 2002, and the like are loaded with predetermined software (program) on the hardware so that the processor 2001 Means that a process is executed by performing an arithmetic operation and controlling communication by the communication device 2004 and reading and / or writing of data in the memory 2002 and the storage 2003. The same applies to the aircraft 10 and the user terminal 30.

  In FIG. 6, the acquisition unit 21 of the server device 20 determines whether or not the abnormality information generated by the detection unit 11 of the flying object 10 has been acquired via the network 2 (step S11). When the acquisition unit 21 acquires the abnormality information (step S11; Yes), the estimation unit 22 estimates the falling range of the flying body 10 based on the flight state of the flying body 10 included in the abnormality information (step S12). . For example, FIG. 7 is a plan view illustrating the relationship between the falling range F of the aircraft 10 on the ground and the wireless communication ranges (cells) C1, C2, C3 of the three base stations. The falling range F of the flying object 10 estimated by the estimation unit 22 in this example is a circular range centered on an area where the wireless communication range C1 and the wireless communication range C2 overlap.

  Next, the transmission control unit 23 identifies the user terminal 30 corresponding to the range estimated by the estimation unit 22, that is, the user terminal 30 that is the destination of the drop information (step S13). In the case of the example in FIG. 7, the transmission control unit 23 specifies one or more base stations (base stations corresponding to the wireless communication ranges C1 and C2) that include the fall range F in the wireless communication range, and the wireless of the specified base station is specified. The user terminals 30a, 30b, 30c, 30d existing in the communication range (wireless communication ranges C1, C2) are specified as the user terminals 30 to which the drop information is transmitted. That is, in the example of FIG. 7, the entire wireless communication ranges C1 and C2 include a range that is not estimated as the falling range F of the flying object 10, but the transmission control unit 23 does not include the wireless communication ranges C1 and C2. The user terminal 30 located in the area is specified as the destination user terminal corresponding to the fall range.

  Then, the transmission control unit 23 transmits the drop information to the specified user terminal 30 via the network 2 (step S14). Upon receiving the drop information, the user terminal 30 notifies the user that there is at least one of characters, an image, a sound, a vibration, or a light, that the flying object 10 is in a range where the flying object 10 falls. The user who notices this takes actions such as looking up at the sky and seeing the situation, or evacuating indoors.

  According to the embodiment described above, it is possible to notify the user of the possibility that the flight vehicle 10 will fall even to a user who is in a position where the sound or light emitted from the flight vehicle 10 does not reach, for example. That is, more reliable notification is realized for people on the ground.

[Modification]
The present invention is not limited to the above embodiments. The embodiment described above may be modified as follows. Further, the following two or more modified examples may be combined and implemented.
[Modification 1]
In the above embodiment, the drop information of the flying object 10 was transmitted to the user terminal 30, but in addition to this, a warning that the flying object 10 itself may be dropped by sound or light when dropped. May be issued to the user.

[Modification 2]
In the embodiment, the estimation unit 22 estimates the falling range of the aircraft 10 by calculation using the equation of motion based on the flight state of the aircraft 10 (this is referred to as the first estimation method). Instead of this, the estimation unit 22 may estimate the wireless communication range of the base station 3 to which the flying body 10 wirelessly connects and performs data communication, as the falling range in which the flying body 10 falls (this). Is referred to as the second estimation method). Since the base station 3 to which the air vehicle 10 wirelessly connects is located relatively close to the air vehicle 10, such a wireless communication range (cell) of the base station 3 may be regarded as a falling range of the air vehicle 10. become.

[Modification 3]
Relatively, the first estimation method has a low estimation processing speed but high estimation accuracy, whereas the second estimation method has a high estimation processing speed but poor estimation accuracy. Therefore, the estimation unit 22 may selectively use the estimation method according to the altitude of the flying body 10, that is, the time until the flying body 10 falls to the ground. For example, when the altitude of the flying body 10 is higher than or equal to a threshold, the estimating unit 22 can secure a certain amount of time until the flying body 10 falls to the ground. When the altitude of the flying object 10 is lower than the threshold value, the time until the flying object 10 falls to the ground is short, so the speed of the estimation process is high, but the estimation accuracy is high. The second estimation method with low That is, the estimation unit 22 calculates the first estimation method of estimating the range of the ground on which the aircraft 10 falls based on the flight state of the aircraft 10, and the wireless communication range of the base station wirelessly connected to the aircraft 10. Any one of the second estimation methods for estimating the range of the ground on which the aircraft 10 falls may be used depending on the altitude of the aircraft.

[Modification 4]
The transmission control unit 23 may specify the user terminal 30 included in the fall range estimated by the estimation unit 22 based on the distances from the plurality of base stations 3 to the user terminal 30. Specifically, since the position of the user terminal 30 can be measured by the so-called base station positioning, which is the difference in the arrival time of the radio signal from each base station 3 to the user terminal 30, the transmission control unit 23 performs the positioning in this way. The user terminal 30 included in the fall range estimated by the estimation unit 22 among the user terminals 30 may be specified as the destination of the fall information. For example, in the example of FIG. 7, the user terminal included in the fall range F is specified as the destination of the fall information. In addition to the base station positioning, when the user terminal 30 has a positioning function such as GPS, the transmission control unit 23 includes the positioning position measured by the user terminal 30 in the fall range estimated by the estimation unit 22. The user terminal 30 as described above may be specified as the transmission destination.

[Modification 5]
In the embodiment, the detection unit 11 of the flying object 10 has a range (threshold value) in which there is a possibility of a fall as a range (threshold value) of an abnormal value of the sensor 1008 and a range (threshold value) of the positioning result of the positioning device 1009. ) Is stored in advance by experiment or simulation, and the threshold is used to detect an abnormality. You may make it use the threshold value when determining the abnormality which may fall like this according to the altitude of the flying body 10 (namely, the time until the flying body 10 falls to the ground). For example, when the flying object 10 has a low altitude, the drop information is transmitted even if the abnormality is a little (the threshold value for determining an abnormality is lowered). (Increase the threshold value for determining abnormality). That is, the server device 20 includes an acquisition unit that compares the state of the flying object 10 with a threshold value that differs according to the altitude of the flying object 10 to acquire the result of detecting the abnormality of the flying object 10, and transmits the result. The control unit 23 determines whether or not to send the drop information according to the result acquired by the acquisition unit.

[Modification 6]
Among the user terminals 30 included in the fall range estimated by the estimation unit 22, the transmission control unit 23 determines the user terminal 30 existing outdoors and the user terminal 30 existing indoors, and the user terminal existing outdoors. The drop information may be transmitted to 30. Specifically, the transmission control unit 23 stores map information capable of discriminating between indoors and outdoors, and the position of the user terminal 30 as a transmission destination (for example, based on base station positioning) corresponds to indoors in the map information. It is determined whether the position is a position to be opened or a position corresponding to the outdoors.

[Modification 7]
A method is known in which, in a wireless communication network, a position where a mobile terminal such as a mobile phone or a smart phone is located is grasped on a cell-by-cell basis of a base station and the population is estimated, for example, by time zone or area. The transmission control unit 23 may transmit the fall information according to the population density specified by the population estimation method represented by such an example. The transmission control unit 23 may transmit, for example, different types of fall information depending on the population density, or may transmit the fall information at different frequencies and times depending on the population density.

[Modification 8]
In the embodiment, the estimation unit 22 estimates the fall range when the flying body 10 starts to fall at the time of abnormality detection. Instead of this, the estimation unit 22 can estimate the time when the flying body 10 begins to fall in the calculation using the abnormal value (for example, there is a possibility that the flying body 10 will fall after a lapse of time T after the abnormal value E is detected. For example, the fall range may be estimated when the flying body 10 starts to drop at the start of the fall.

[Modification 9]
The flying body 10 may replace at least part of the function of the server device 20 (information processing device), or the base station 3 may replace at least part of the function of the server device 20 (information processing device). May be. When the aircraft 10 substitutes all the functions of the server device 20 (information processing device), the aircraft 10 functions as the information processing device of the present invention, and the base station 3 functions as the server device 20 (information processing device). When substituting all the functions, the base station 3 functions as the information processing device of the present invention. Further, in the embodiment, the detection unit 11 of the flying object 10 detects an abnormality, but the server device 20 acquires the detection value of the sensor 1008 and the positioning result of the positioning device 1009 itself from the flying object 10 and determines whether or not there is an abnormality. You may judge whether. Further, in the above-described embodiment, the method of measuring the position of the flying object 10 is not limited to the method using GPS. The position of the air vehicle 10 may be measured by a method that does not use GPS.
