<First Embodiment>
[Configuration and basic operation]
FIG. 1 is a diagram showing a configuration of a radio wave measurement system according to the first embodiment of the present invention.

  With reference to FIG. 1, the radio wave measurement system 101 includes traffic wireless devices 10 </ b> A, 10 </ b> B, 10 </ b> C and an unmanned air vehicle 11.

  Hereinafter, each of the traffic radio apparatuses 10A, 10B, and 10C is also referred to as a traffic radio apparatus 10. In this example, the radio wave measurement system 101 includes three traffic wireless devices 10, but may be configured to include a smaller number or a greater number of traffic wireless devices 10.

  The traffic radio apparatus 10 is a roadside radio apparatus installed on the roadside of the road 1, for example. The traffic radio device 10 receives traffic information, which is information related to traffic, from a central device (not shown), and transmits the received traffic information to the road 1. Specifically, the traffic wireless device 10 transmits radio waves including traffic information toward the road 1. The traffic information is transmitted by being divided into a plurality of packets, for example.

  The vehicle 2 traveling on the road 1 receives the road traffic information transmitted from the traffic radio device 10 when passing near the traffic radio device 10.

  The unmanned air vehicle 11 is a drone, for example, and can autonomously fly. The unmanned air vehicle 11 stores map information in the surrounding area in advance. The map information includes, for example, road position information and target point position information described later.

  The unmanned aerial vehicle 11 is equipped with a GPS device, receives GPS radio waves, and creates GPS information indicating the current position and current time of the unmanned air vehicle 11 from the received radio waves.

  The unmanned air vehicle 11 recognizes the positional relationship between the unmanned air vehicle 11, the road 1, and the target point based on the map information and the GPS information. Based on the recognized positional relationship, the unmanned air vehicle 11 measures the radio wave transmitted from the traffic radio device 10 while flying over the road 1 along the road 1 after moving to the target point.

  Specifically, the traffic radio device 10 measures the received power of the radio wave including traffic information transmitted from the traffic radio device 10 as a measurement related to the radio wave. Hereinafter, the received power of radio waves including traffic information is also simply referred to as received power of traffic information. The unmanned air vehicle 11 also measures its own altitude from the road 1 when measuring the received power.

  The unmanned air vehicle 11 receives, for example, the received power, the position and height of the unmanned air vehicle 11 when the received power is measured, based on the map information, the GPS information, the received power measurement result, and the altitude measurement result. Create radio wave information including the time when power was measured.

  That is, the radio wave information is information in which the measurement result of the received power, the measurement result of the altitude of the unmanned air vehicle 11, and the position and time of the unmanned air vehicle 11 are associated with each other. The unmanned air vehicle 11 stores the created radio wave information in its own storage unit.

  The unmanned air vehicle 11 periodically measures received power and the like while flying. The unmanned air vehicle 11 updates the radio wave information by adding the measurement result to the radio wave information every time measurement is performed.

  FIG. 2 is a diagram illustrating an example of a route on which an unmanned air vehicle flies in the radio wave measurement system according to the first embodiment of the present invention.

  With reference to FIG. 2, in this example, the traffic radio apparatuses 10 </ b> A, 10 </ b> B, and 10 </ b> C are measurement targets related to radio waves by the unmanned air vehicle 11.

  Specifically, the unmanned air vehicle 11 can be connected to a recording medium such as a USB memory, for example, and receives position information indicating the target points TA, TB, and TC from the information processing apparatus 12 that is a personal computer via the recording medium. Acquire and fly based on the acquired position information.

  For example, the unmanned air vehicle 11 first flies to the target point TA. The target point TA is set above the road 1 near the traffic wireless device 10A.

  When the unmanned air vehicle 11 arrives at the target point TA, the unmanned air vehicle 11 measures the radio wave status from the traffic radio apparatus 10A, that is, the received power of the radio wave, while flying along the extending direction of the road 1. The unmanned air vehicle 11 determines whether the measurement result of the received power is normal or abnormal.

  In this example, the unmanned air vehicle 11 determines that there is no abnormality in the received power of the radio wave from the traffic radio apparatus 10A. Then, the unmanned aerial vehicle 11 flies to the direction to the traffic radio device 10B, which is the traffic radio device 10 whose reception power is to be measured next, specifically, to the target point TB corresponding to the traffic radio device 10B. The target point TB is set above the road 1 near the traffic wireless device 10B.

  When the unmanned air vehicle 11 arrives at the target point TB, the unmanned air vehicle 11 measures the received power of the radio wave from the traffic wireless device 10B while flying along the extending direction of the road 1.

  In this example, the unmanned air vehicle 11 determines that there is no abnormality in the received power of the radio wave from the traffic radio apparatus 10B. The unmanned aerial vehicle 11 then flies to the direction of the traffic radio device 10C, which is the traffic radio device 10 whose reception power is to be measured next, specifically, to the target point TC corresponding to the traffic radio device 10C. The target point TC is set above the road 1 near the traffic wireless device 10C.

  When the unmanned air vehicle 11 arrives at the target point TC, the unmanned air vehicle 11 measures the received power of the radio wave from the traffic wireless device 10C while flying along the extending direction of the road 1.

  Here, the unmanned air vehicle 11 determines that the received power is abnormal, for example, the received power of the radio wave from the traffic wireless device 10C is extremely small.

  In this case, for example, the unmanned aerial vehicle 11 turns around the traffic wireless device 10C in order to obtain more detailed information on the status of the radio waves transmitted from the traffic wireless device 10C. Measure the received power. That is, the unmanned air vehicle 11 measures the received power of radio waves on the road and other than on the road.

  Hereinafter, each of the target points TA, TB, and TC respectively set corresponding to the traffic radio apparatuses 10A, 10B, and 10C is also referred to as a target point T.

  The target point T is not limited to the position above the road 1 in the vicinity of the traffic wireless device 10 and may be set, for example, at the installation position of the traffic wireless device 10.

  Further, one target point T may be set for one traffic radio apparatus 10 as in this example, or one target point T may be set for a plurality of traffic radio apparatuses 10.

[Operation]
Next, the operation when the unmanned air vehicle according to the first embodiment of the present invention performs measurement related to the radio wave transmitted from the traffic wireless device will be described.

  Each device in the radio wave measurement system 101 includes a computer, and an arithmetic processing unit such as a CPU in the computer reads and executes a program including a part or all of each step in the following flowchart from a memory (not shown). Each of the programs of the plurality of apparatuses can be installed from the outside. The programs of the plurality of apparatuses are distributed while being stored in a recording medium.

  FIG. 3 is a flowchart showing the procedure of the measurement process of the unmanned air vehicle according to the first embodiment of the present invention.

  With reference to FIG. 3, first, the unmanned air vehicle 11 flies to a target point T corresponding to the traffic wireless device 10 whose received power is to be measured, for example, from a certain location away from the traffic wireless device 10 (step S10). .

  Next, when the unmanned air vehicle 11 arrives at the target point T, it starts the measurement flight process. The measurement flight process is a process in which the unmanned air vehicle 11 flies around the traffic radio apparatus 10. The measurement flight process includes a measurement flight process F and a measurement flight process S.

  Here, the unmanned air vehicle 11 performs a measurement flight process F that is a process of flying above the road 1 along the extending direction of the road 1. The measurement flight process S will be described later.

  Next, the unmanned air vehicle 11 measures received power while flying above the road 1 along the extending direction of the road 1 (step S12). Specifically, the unmanned air vehicle 11 measures the received power of radio waves from the traffic radio apparatus 10 </ b> A and its altitude from the road 1.

  Here, the distance Lm that the unmanned air vehicle 11 flies along the extending direction of the road 1 while measuring a certain traffic wireless device 10 is, for example, 800 m. Specifically, the unmanned aerial vehicle 11 flies while measuring from a point about 400 m in front of the traffic radio device 10 on the road 1 to a point about 400 m beyond the traffic radio device 10.

  The distance Lm may be greater than 800 m or may be smaller, for example, a minimum of about 400 m. When the distance Lm is 400 m, the unmanned aerial vehicle 11 flies while measuring from a point about 200 m in front of the traffic wireless device 10 on the road 1 to a point about 200 m beyond the traffic wireless device 10.

  As described above, the unmanned air vehicle 11 creates radio wave information based on the measurement result. For example, the unmanned air vehicle 11 repeatedly measures the received power and altitude while performing the measurement flight process F.

  Each time the unmanned air vehicle 11 measures the received power, the measured received power, the position and height of the unmanned air vehicle 11 when the received power is measured, and the time when the received power is measured are used as radio wave information. The radio wave information is updated by adding.

  Next, the unmanned air vehicle 11 determines whether or not the measurement result of the received power is abnormal based on the created radio wave information (step S13). Specifically, for example, in the unmanned air vehicle 11, the measured value of the received power of the radio wave from the traffic wireless device 10 is significantly lower than the expected received power from the positional relationship between the traffic wireless device 10 and itself. In this case, it is determined that there is an abnormality in the measurement result of the received power.

  If the unmanned air vehicle 11 determines that there is no abnormality in the measurement result of the received power (NO in step S13), in addition to the traffic radio device 10 that has already measured the received power, the traffic radio device that should measure the received power. 10 is checked (step S14).

  If there is another traffic wireless device 10 whose received power is to be measured (YES in step S14), the unmanned air vehicle 11 flies to the next target point T corresponding to the traffic wireless device 10 (step S15). .

  Next, when the unmanned air vehicle 11 arrives at the next target point T, it performs a measurement flight process F (step S11). The unmanned air vehicle 11 measures the received power while flying above the road 1 along the extending direction of the road 1 (step S12).

  Next, the unmanned air vehicle 11 determines whether there is an abnormality in the measurement result of the received power based on the radio wave information to which the measurement result or the like is added (step S13). Here, the unmanned air vehicle 11 determines that there is an abnormality in the measurement result of the received power (YES in step S13).

  Next, the unmanned air vehicle 11 performs a measurement flight process S (step S16). The measurement flight process S is, for example, a process in which the unmanned air vehicle 11 turns around the traffic radio apparatus 10.

  Here, the radius Rm of the flight path when the unmanned air vehicle 11 turns around the traffic radio apparatus 10 is, for example, 400 m. The radius Rm may be larger than 400 m or smaller, for example, a minimum of about 200 m.

  The unmanned aerial vehicle 11 measures received power even during the measurement flight process S. That is, during the measurement flight process S, the unmanned air vehicle 11 also measures radio waves other than on the road (step S17).

  Next, the unmanned air vehicle 11 checks whether or not there is a traffic radio device 10 that should measure the received power in addition to the traffic radio device 10 that has already measured the received power (step S14).

  If there is no other traffic radio device 10 whose received power is to be measured (NO in step S14), the unmanned air vehicle 11 flies to a preset point such as a flight start location and lands.

  For example, the user collects the unmanned air vehicle 11 that has landed, connects a recording medium such as a USB memory, and copies the radio wave information stored in the unmanned air vehicle 11 to the recording medium. Then, the user connects the recording medium on which the radio wave information is copied to the information processing apparatus 12 and causes the information processing apparatus 12 to display the contents of the radio wave information.

  Even if the unmanned air vehicle 11 determines that the measurement result of the received power is abnormal (YES in step S13), the unmanned air vehicle 11 measures the radio wave condition only on the road, The structure which does not measure may be sufficient.

  Next, a procedure for displaying the contents of the radio wave information by the information processing apparatus according to the first embodiment of the present invention will be described.

  FIG. 4 is a flowchart showing a procedure of display processing in the information processing apparatus according to the first embodiment of the present invention.

  First, the information processing apparatus 12 acquires radio wave information created by the unmanned air vehicle 11 from a recording medium connected to the information processing apparatus 12 (step S50).

  Next, the information processing apparatus 12 performs control to display the content based on the acquired radio wave information on its own display (step S51). Specifically, the information processing apparatus 12 creates image information based on the acquired radio wave information, and displays the content of the created image information on its own display.

  FIG. 5 is a diagram showing a configuration of the unmanned air vehicle according to the first embodiment of the present invention.

  Referring to FIG. 5, the unmanned air vehicle 11 includes a storage unit 31, a storage acquisition unit (acquisition unit) 32, an altitude measurement unit 33, a flight processing unit 34, a current location acquisition unit 35, and a drive unit 36.

The map information may be configured not to include the position information of the traffic wireless device 10.

  The measurement target information is, for example, information registered by the user in the unmanned air vehicle 11 using a recording medium such as a USB memory.

  The memory acquisition unit 32 acquires position information of a target point, road position information, and the like. Specifically, the storage acquisition unit 32 acquires map information and measurement target information from the storage unit 31 and outputs the acquired information to the flight processing unit 34.

  The current location acquisition unit 35 receives GPS radio waves and creates GPS information indicating the current position and current time of the unmanned air vehicle 11 from the received GPS radio waves. Then, the current location acquisition unit 35 outputs the created GPS information to the flight processing unit 34 and the radio wave information creation unit 40.

  The flight processing unit 34 recognizes the positional relationship between the unmanned air vehicle 11, the road 1, the traffic wireless device 10, and the target point T based on the map information received from the memory acquisition unit 32 and the GPS information received from the current location acquisition unit 35. To do.

  The flight processing unit 34 performs a process of flying its own unmanned air vehicle 11 to the target point T based on the map information acquired by the memory acquisition unit 32. Specifically, the flight processing unit 34 corresponds to the traffic radio device 10 that should first measure the received power based on the positional relationship between the recognized unmanned air vehicle 11, the road 1, the traffic radio device 10, and the target point T. The process which makes the self-unmanned air vehicle 11 fly to the target point T to perform is performed.

  More specifically, the flight processing unit 34 creates control information for flying the unmanned air vehicle 11 to the target point T, and outputs the created control information to the drive unit 36.

  The drive unit 36 includes, for example, a plurality of motors respectively connected to a plurality of propellers included in the unmanned air vehicle 11. The drive unit 36 drives each motor based on the control information received from the flight processing unit 34. At that time, the drive unit 36 adjusts the rotation of the motor so that the unmanned air vehicle 11 maintains a posture suitable for flight.

  The flight processing unit 34 recognizes that its own unmanned air vehicle 11 has arrived at the target point T based on the GPS information received from the current location acquisition unit 35. The flight processing unit 34 is a measurement flight process for causing the unmanned air vehicle 11 to fly around the traffic wireless device 10 capable of transmitting radio waves including traffic information after the unmanned air vehicle 11 arrives at the target point T. I do.

  Specifically, the flight processing unit 34 performs the measurement flight process F based on the position information of the road 1 acquired by the memory acquisition unit 32 and the GPS information created by the current location acquisition unit 35, and the flight for measurement In process F, the unmanned air vehicle 11 is caused to fly on the road around the traffic radio apparatus 10.

  More specifically, for example, the flight processing unit 34 creates control information for allowing the unmanned air vehicle 11 to fly on the road along the extending direction of the road 1 around the traffic wireless device 10. The created control information is output to the drive unit 36.

  The radio wave measurement unit 39 performs measurement related to the radio wave transmitted from the traffic wireless device 10 when the measurement flight process is being performed. Specifically, the radio wave measuring unit 39 receives a radio wave including traffic information transmitted from the traffic wireless device 10 and measures received power of the traffic information. Then, the radio wave measurement unit 39 outputs received power information indicating the measurement result of the received power to the radio wave information creation unit 40.

  In addition, when the time zone during which the traffic wireless device 10 transmits a radio wave including traffic information is determined in advance and the radio wave measuring unit 39 recognizes the time zone, the radio wave measurement unit 39 limits the radio wave to the time zone. May be measured. In addition, when the frequency channel used by the traffic radio apparatus 10 is determined in advance and the frequency channel is recognized, the radio wave measurement unit 39 measures the reception power of the radio wave only for the frequency channel. May be.

  The altitude measurement unit 33 measures the altitude of the unmanned air vehicle 11 from the road 1 when the reception power is measured by the radio wave measurement unit 39. Specifically, for example, the radio wave measurement unit 39 outputs a measurement notification to the altitude measurement unit 33 at the measurement timing of the received power. Upon receiving the measurement notification from the radio wave measurement unit 39, the altitude measurement unit 33 measures the distance between the unmanned air vehicle 11 and the road 1, that is, the altitude from the road 1 of the unmanned air vehicle 11 using, for example, infrared rays. Then, the altitude measuring unit 33 creates altitude information indicating the altitude measurement result, and outputs the created altitude information to the radio wave information creating unit 40.

  The radio wave information creation unit 40 creates radio wave information based on the GPS information received from the current location acquisition unit 35, the altitude information received from the altitude measurement unit 33, and the received power information received from the radio wave measurement unit 39. The radio wave information includes the measurement result of the traffic information received power by the radio wave measurement unit 39, the position of the unmanned air vehicle 11, the result of the altitude measurement by the altitude measurement unit 33 when the radio wave measurement unit 39 performs the measurement, This is information in which time is associated with each other. The radio wave information creation unit 40 stores the created radio wave information in the storage unit 31.

  The radio wave information creation unit 40 periodically acquires GPS power, altitude information, and traffic power received power information from the current location acquisition unit 35, altitude measurement unit 33, and radio wave measurement unit 39, respectively. For example, the radio wave information creating unit 40 updates the radio wave information based on these pieces of information each time the pieces of information are acquired.

  The determination unit 37 determines whether the received power is normal or abnormal based on the radio wave information stored in the storage unit 31, specifically, the measurement result of the received power of the traffic information. Then, 37 determines whether the traffic radio apparatus 10 is normal or abnormal based on the determination result.

  Specifically, when the positional relationship between the unmanned air vehicle 11 and the traffic wireless device 10 satisfies a predetermined condition, the determination unit 37 determines that the measured value of the received power of traffic information from the traffic wireless device 10 is a predetermined value. If the measured value of the received power is abnormal, that is, it is determined that the traffic radio apparatus 10 is abnormal.

  For example, when the determination unit 37 determines that there is an abnormality in the measurement result of the received power for the traffic radio device 10 of interest, the flight processing unit 34 performs the measurement flight processing S, and the flight processing unit S Let the unmanned air vehicle fly further on the road.

  Specifically, for example, the flight processing unit 34 turns the unmanned air vehicle 11 around the traffic wireless device 10.

  The radio wave information creation unit 40 receives GPS information, altitude information, and traffic information received power information from the current location acquisition unit 35, altitude measurement unit 33, and radio wave measurement unit 39 while the measurement flight process S is being performed. Is acquired periodically. For example, the radio wave information creating unit 40 updates the radio wave information based on these pieces of information each time the pieces of information are acquired.

  FIG. 6 is a diagram showing the configuration of the information processing apparatus according to the first embodiment of the present invention.

  Referring to FIG. 6, information processing device 12 includes a display unit 51, an acquisition unit 52, and a processing unit (display control unit) 53.

  For example, the acquisition unit 52 acquires radio wave information created by the unmanned air vehicle 11. Specifically, the acquisition unit 52 obtains the result of measuring the radio wave transmitted from the traffic wireless device 10 when the unmanned air vehicle 11 is flying around the traffic wireless device 10 and the position of the unmanned air vehicle 11. Acquire associated radio wave information.

  For example, the user collects the unmanned air vehicle 11 that has finished measuring the received power for each traffic wireless device 10, connects a recording medium such as a USB memory, and is stored in the storage unit 31 of the unmanned air vehicle 11. Copy the current radio wave information to the recording medium.

  The acquisition unit 52 acquires radio wave information from a recording medium connected to its own unmanned air vehicle 11 and outputs the acquired radio wave information to the processing unit 53. The acquisition unit 52 is not limited to a configuration that acquires radio wave information via a recording medium, and performs, for example, wireless communication with the unmanned air vehicle 11 using infrared rays or radio waves, or wired communication using a communication cable. Thus, the radio wave information may be directly acquired from the unmanned air vehicle 11.

  The processing unit 53 performs control to display contents based on the radio wave information acquired by the acquisition unit 52. Specifically, the processing unit 53 creates screen information indicating the content to be displayed on the display unit 51 based on the radio wave information received from the acquisition unit 52, and outputs the created screen information to the display unit 51.

  Display unit 51 includes a display, and displays the contents of the screen information received from processing unit 53 on the display.

  FIG. 7 is a diagram showing an example of a screen displayed on the display of the information processing apparatus according to the first embodiment of the present invention.

  FIG. 7 shows a footprint indicating the relationship between the measurement position and the reception intensity, created based on the radio wave information. Referring to FIG. 7, each block M indicates a position where reception power is measured. In this example, the measurement result is shown when the measurement is performed not only on the road but also over a wide range including the road periphery.

  A black block M indicates a measurement result on the road 1. On road 1, the received power is large because the view from traffic radio device 10 is good. A hatched block M indicates a measurement result in a place where a building or the like exists. In places where there are buildings, the received power is small because radio waves are blocked. The white block M has shown the measurement result between buildings. Received power is moderate because radio waves go around between buildings.

  When the unmanned air vehicle 11 according to the first embodiment of the present invention determines that there is an abnormality in the received power of the traffic information, the unmanned air vehicle 11 turns around the traffic wireless device 10 that is the transmission source of the traffic information. However, the present invention is not limited to this. For example, in the unmanned air vehicle 11, when the determination unit 37 determines that the received power of the traffic information is abnormal, the flight processing unit 34 is located at the time when this determination is made. The structure which performs the flight process which makes the said unmanned air vehicle 11 fly the circumference | surroundings of the spot which had been may be sufficient. Specifically, for example, the flight processing unit 34 causes the unmanned air vehicle 11 to turn around the point around the point. At this time, the radius Rn of the flight path of the unmanned air vehicle 11 is, for example, 70 m. The radius Rn may be larger than 70 m or smaller, for example, it may be at least about 30 m.

  With such a configuration, for example, since it is possible to measure in more detail about an area where the radio wave condition is bad, for example, when an obstacle that blocks radio waves from the traffic wireless device 10 is the cause of the abnormality, the cause Can be easily grasped.

  In addition, the unmanned air vehicle 11 according to the first embodiment of the present invention is configured to perform measurement related to the radio wave transmitted from the traffic wireless device 10 after arriving at the target point T, but the present invention is not limited thereto. It is not a thing. For example, in the unmanned air vehicle 11, the flight processing unit 34 performs a flight process for causing the unmanned air vehicle 11 to fly in a state where the target point T is not set. The radio wave measurement unit 39 performs measurement related to radio waves transmitted from the traffic wireless device 10 when the flight process is being performed. Specifically, for example, the flight processing unit 34 causes the unmanned air vehicle 11 to fly all over the preset area. The radio wave measuring unit 39 measures the received power of the radio wave transmitted from the traffic wireless device 10 during the period when the unmanned air vehicle 11 is flying in the area.

The reception success rate is measured.

  Specifically, each packet transmitted from the traffic radio apparatus 10 includes a sequence number. The radio wave measurement unit 39 receives the radio wave transmitted from the traffic radio device 10 and extracts a packet from the received radio wave. The radio wave measuring unit 39 confirms the sequence number included in the extracted packet, and counts the number of packets that have been successfully received and the number of packets that have failed to be received. The radio wave measuring unit 39 calculates a reception success rate based on these counted numbers.

  When the reception success rate calculated by the radio wave measurement unit 39 is below a predetermined threshold, the determination unit 37 determines that the measurement result by the radio wave measurement unit 39 is abnormal, that is, the traffic wireless device 10 is abnormal. .

  By the way, conventionally, in the inspection of the radio wave condition transmitted from the radio device installed on the roadside, for example, a user having a measurement device, that is, an inspector, measures the radio wave status while walking around the radio device, A method of measuring the radio wave condition while traveling on a road with an installed vehicle is used.

  However, in such a method, since the inspector needs to go to the installation location of the target traffic wireless device 10 for each inspection, the burden of the inspection becomes large.

  In addition, for example, when the radio wave condition is measured while traveling on a road with a vehicle, even if an abnormality is found in the measurement result, the vehicle must travel according to the traffic condition. There is a problem that measurement cannot be performed. In addition, in this case, since the radio wave condition other than the road cannot be measured, there is a problem that it is difficult to grasp the spread of the radio wave including the road periphery.

  On the other hand, in the unmanned air vehicle according to the first embodiment of the present invention, the flight processing unit 34 performs a flight process for causing the unmanned air vehicle 11 to fly. The radio wave measurement unit 39 performs measurement on radio waves transmitted from the traffic wireless device 10 capable of transmitting radio waves including traffic information when the flight process is being performed. The radio wave information creating unit 40 creates radio wave information in which the measurement result by the radio wave measuring unit 39 is associated with the position of the unmanned air vehicle 11.

The flight processing unit 34 performs a flight process for flying the self-unmanned aerial vehicle 11 to the target point based on the position information acquired by the memory acquisition unit 32. The flight processing unit 34 performs a measurement flight process in which the unmanned aerial vehicle 11 flies around the traffic wireless device 10 capable of transmitting radio waves including traffic information after arrival of the unmanned aircraft 11 at the target point. Do. The radio wave measurement unit 39 performs measurement related to the radio wave transmitted from the traffic wireless device 10 when the measurement flight process is being performed. The radio wave information creating unit 40 creates radio wave information in which the measurement result by the radio wave measuring unit 39 is associated with the position of the own unmanned air vehicle 11.

  In the unmanned air vehicle according to the first embodiment of the present invention, the determination unit 37 determines whether the measurement result by the radio wave measurement unit 39 is normal or abnormal.

  With such a configuration, when there is an abnormality in the measurement result, for example, the unmanned air vehicle 11 can automatically perform processing such as measuring the state of the radio wave transmitted from the traffic wireless device 10 in more detail. it can.

  Moreover, in the unmanned air vehicle according to the first embodiment of the present invention, the memory acquisition unit 32 further acquires road position information. Based on the road position information acquired by the memory acquisition unit 32, the flight processing unit 34 causes the unmanned air vehicle 11 to fly on the road around the traffic wireless device 10 in the measurement flight processing, and on the road. When the determination unit 37 determines that the measurement result is abnormal, the self-unmanned air vehicle 11 is further caused to fly other than on the road in the measurement flight process.

  With such a configuration, when there is an abnormality in the measurement result of the radio wave situation, the radio wave situation in a wide range including other than the road is measured, and the cause of the abnormality such as the intensity distribution of the radio wave transmitted from the traffic wireless device 10 More determinable material can be collected.

  Moreover, in the unmanned air vehicle according to the first embodiment of the present invention, the radio wave information creation unit 40 creates radio wave information in which the measurement result by the radio wave measurement unit 39 is associated with the time.

  With such a configuration, it is possible to grasp a change in radio wave status over time using the time associated with the measurement result.

  In the unmanned air vehicle according to the first embodiment of the present invention, the altitude measurement unit 33 measures the altitude of the unmanned air vehicle 11. The radio wave information creation unit 40 creates radio wave information in which the measurement result by the radio wave measurement unit 39 is associated with the result of the altitude measurement by the altitude measurement unit 33 when the radio wave measurement unit 39 performs measurement.

  With such a configuration, a change due to the altitude of the radio wave condition can be grasped using the altitude associated with the measurement result.

  Moreover, in the unmanned air vehicle according to the first embodiment of the present invention, the radio wave measurement unit 39 measures the received power of the radio wave in the unmanned air vehicle 11 as the measurement.

  With such a configuration, it is possible to more accurately determine the status of radio waves transmitted from the traffic radio device 10 using the received power of radio waves.

  For example, the radio wave measuring unit 39 measures the received power of the radio wave for each traffic wireless device 10. For example, the radio wave measuring unit 39 measures the received power of the radio wave for each predetermined time zone or for each frequency channel.

  Moreover, in the modification of the 1st Embodiment of this invention, traffic information is divided | segmented into a some packet, and is transmitted. As the measurement, the radio wave measurement unit 39 measures the success rate of reception of the packet included in the radio wave in the unmanned air vehicle 11.

  With such a configuration, it is possible to more accurately determine the state of the radio wave transmitted from the traffic wireless device 10 using the packet reception success rate.

  In addition, the radio wave measurement unit 39 measures both the packet reception success rate and the reception power, so that the status of the radio wave transmitted from the traffic wireless device 10 can be determined in detail. Specifically, for example, when the reception success rate of a packet transmitted from the traffic radio apparatus 10 is low even though the reception power from the traffic radio apparatus 10 is sufficiently large, the traffic radio apparatus 10 is in another traffic radio. It can be determined that there is a possibility of interference from the device 10.

  In this case, for example, the presence or absence of interference by the other traffic radio apparatus 10 is confirmed by reducing the transmission power of the other traffic radio apparatus 10 that transmits information in the same time zone as the traffic radio apparatus 10. Can do.

  In the information processing apparatus 12 according to the first embodiment of the present invention, the acquisition unit 52 is when the unmanned aerial vehicle 11 is flying around the traffic radio apparatus 10 capable of transmitting radio waves including traffic information. Radio wave information in which the radio wave measurement result transmitted from the traffic radio apparatus 10 is associated with the position of the unmanned air vehicle 11 is acquired. The processing unit 53 performs control to display contents based on the radio wave information acquired by the acquisition unit 52.

  With such a configuration, the state of the radio wave transmitted from the traffic wireless device 10 can be confirmed on the screen without the user directly measuring at the site. Therefore, the burden of the inspection of the traffic radio apparatus 10 can be reduced.

  Next, another embodiment of the present invention will be described with reference to the drawings. In the drawings, the same or corresponding parts are denoted by the same reference numerals and description thereof will not be repeated.

<Second Embodiment>
This embodiment relates to a radio wave measurement system in which the determination method of normality and abnormality of measurement results is different from that of the radio wave measurement system according to the first embodiment. The contents other than those described below are the same as those of the radio wave measurement system according to the first embodiment.

  FIG. 5 also shows the configuration of the unmanned air vehicle 11 according to the second embodiment of the present invention.

  Referring to FIG. 5, the storage unit 31 stores past measurement results related to radio waves transmitted from the traffic wireless device 10. Specifically, for example, the storage unit 31 flies along the route information indicating the flight route on the road on which the unmanned air vehicle 11 flew when the received power of the traffic wireless device 10 was measured in the past, and the flight route. The radio wave information created by performing the measurement is stored.

  The flight processing unit 34 acquires route information from the storage unit 31 via the storage acquisition unit 32, and causes the unmanned air vehicle 11 to fly along the past flight route indicated by the route information in the measurement flight processing F. For example, the radio wave measurement unit 39 measures received power when the current position of the unmanned aerial vehicle 11 and the position where the unmanned air vehicle 11 has measured in the past approximately coincide with each other while performing the measurement flight process F. .

  The determination unit 37 determines whether the measurement result by the radio wave measurement unit 39 is normal or abnormal based on the measurement result of the past received power stored in the storage unit 31. Specifically, the determination unit 37 refers to the past radio wave information and the radio wave information created this time, and calculates the RMS error E between the current series of measurement results and the past series of measurement results.

For example, if the unmanned air vehicle 11 has measured n times in the past and this time for the traffic radio apparatus 10, the determination unit 37 calculates the RMS error E according to the following equation (1). However, Xi indicates the i-th measurement value in the current n-time measurement, and Yi indicates the i-th measurement value in the past n-time measurement.

  The determination unit 37 determines that there is an abnormality in the measurement result when the RMS error E is equal to or greater than a predetermined threshold value.

  The determination unit 37 is configured to calculate a correlation coefficient R between the current series of measurement results and the past series of measurement results with reference to the past radio wave information and the current radio wave information. May be.

For example, if the unmanned air vehicle 11 has performed n measurements for the traffic radio apparatus 10 both in the past and this time, the correlation coefficient R is obtained by the following equation (2). However, Xi is the i-th measurement value in the current n measurement, Xa is the average of the measurement value in the current n measurement, and Xp is the standard deviation of the measurement value in the current n measurement. is there. Yi is the i-th measurement value in the past n measurements, Ya is the average of the measurement values in the past n measurements, and Yp is the standard deviation of the measurement values in the past n measurements. is there.

  The determination unit 37 determines that there is an abnormality in the measurement result when the correlation coefficient R is equal to or less than a predetermined threshold value.

  The flight processing unit 34 is configured to cause the unmanned air vehicle 11 to fly along the flight path in the past measurement indicated by the path information in the measurement flight process F, but is not limited thereto. . For example, the flight processing unit 34 may be configured to cause the unmanned air vehicle 11 to fly above or below the past flight path indicated by the path information in the measurement flight process F.

  In this case, the unmanned aerial vehicle 11 changes, for example, the determination criteria for normality and abnormality of the measurement result based on the positional relationship between the flight path in the current measurement and the flight path in the past measurement. Specifically, for example, the unmanned air vehicle 11 stores in advance the content of the influence of the positional relationship on the RMS error E or the correlation coefficient R. Then, the unmanned air vehicle 11 changes the threshold used for determining whether or not there is an abnormality in the measurement result based on the positional relationship and the content of the influence.

  The past measurement result stored in the storage unit 31 is not limited to the measurement result by the unmanned aerial vehicle 11. For example, measurement performed by the measurer using another device while traveling on the road 1 with the vehicle. May be the result.

  As described above, in the unmanned air vehicle according to the second embodiment of the present invention, the storage unit 31 stores past measurement results related to radio waves transmitted from the traffic radio apparatus 10. The determination unit 37 determines whether the measurement result by the radio wave measurement unit 39 is normal or abnormal based on the past measurement result stored in the storage unit 31.

  With such a configuration, for example, when the measurement result obtained by the current measurement is smaller than the measurement result obtained in the normal measurement, it can be determined that there is an abnormality in the measurement result. Therefore, a more correct judgment can be made.

  Since other configurations and operations are the same as those of the radio wave measurement system according to the first embodiment, detailed description thereof will not be repeated here.

  The above embodiment should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
