Description

Technical Field

[0001] The present invention relates to a radio wave information output device and the like.

Background Art

[0002] In wireless communication, radio wave interference is one of the factors causing throughput degradation.

[0003] When radio wave interference occurs and the throughput decreases, the quality of the service provided by wireless communication may deteriorate. Deterioration of service quality includes, for example, disturbances in reproduced video and audio, and deterioration of control accuracy in remote control.

[0004] Therefore, when radio wave interference occurs, it is desirable to take measures against radio wave interference and eliminate the radio wave interference.

[0005] However, factors other than radio wave interference can also cause throughput degradation. Therefore, in order to take measures against radio wave interference, first, it is necessary to investigate whether radio wave interference is occurring.

[0006] A decrease in throughput is generally detected by the occurrence of a deterioration in service quality. And generally, an investigator goes to the site where the service quality has deteriorated, and the investigator investigates the surrounding radio wave conditions and so on to investigate whether radio wave interference is occurring. And when radio wave interference is occurring, the interference source is identified and measures against radio wave interference are taken.

[0007] Also, as related technologies, there are the technologies described in Patent Document 1 to Patent Document 2.

Summary of the Invention

Problems to be Solved by the Invention

[0009] However, the general method of radio wave interference investigation as described above is laborious because the investigator has to go to the site.

[0010] As a method of reducing this labor, a method can be considered in which many sensors installed in the field acquire radio wave information, the management device collects the radio wave information from the sensors, and the investigator conducts a radio wave interference investigation based on the collected information.

[0011] However, there are many radio wave transmission sources in the field. Therefore, if all the information collected from the sensors is provided to the user, a large amount of information will be provided to the user, resulting in information overload for the user. As a result, it takes time to investigate radio wave interference and identify the interference source.

Embodiments for Carrying Out the Invention

[0019] [First Embodiment] The first embodiment of the present invention will be described.

[0020] Note that a specific example of the radio wave information output device 10 in the first embodiment is the radio wave information output device 20 in the second embodiment described later.

[0021] First, a configuration example of the radio wave information output device 10 of the present embodiment will be described. FIG. 1 shows a configuration example of the radio wave information output device 10 of the present embodiment. The radio wave information output device 10 includes a receiving unit 11, a collating unit 12, an output unit 13, and an estimating unit 14.

[0022] The receiving unit 11 receives radio wave information about the received radio waves. The received radio waves are the radio waves received by the radio wave sensor. The radio wave information is information about the radio waves. The radio wave information includes identification information of the radio wave source and position specifying information. The position specifying information is information that can be used to estimate the position of the radio wave source.

[0023] The verification unit 12 verifies whether the received metadata matches the verification metadata. The received metadata is information included in the received radio wave information and is the identification information of the radio wave source. The verification metadata is the identification information of a known radio wave source.

[0024] The estimation unit 14 estimates the position of the source of the unknown radio wave based on the position identification information included in the received radio wave information. The unknown radio wave is a received radio wave whose received metadata does not match any of the verification metadata.

[0025] The output unit 13 outputs unknown radio wave information. The unknown radio wave information is information regarding the position of the source of the unknown radio wave.

[0026] Next, an example of the operation flow of the radio wave information output device 10 of the present embodiment will be described. FIG. 2 shows an example of the operation flow of the radio wave information output device 10 of the present embodiment.

[0027] The receiving unit 11 receives radio wave information about the received radio wave (step S101). The radio wave information includes the identification information of the radio wave source and the position identification information.

[0028] The verification unit 12 verifies whether the received metadata matches the verification metadata (step S102).

[0029] The estimation unit 14 estimates the position of the source of the unknown radio wave based on the position identification information included in the received radio wave information (step S103). The unknown radio wave is a received radio wave whose received metadata does not match any of the verification metadata.

[0030] The output unit 13 outputs unknown radio wave information (step S104). The unknown radio wave information is information regarding the position of the source of the unknown radio wave.

[0031] As described above, in the first embodiment of the present invention, the radio wave information output device 10 includes a receiving unit 11, a collating unit 12, an output unit 13, and an estimating unit 14. The receiving unit 11 receives radio wave information about the received radio wave. The received radio wave is the radio wave received by the radio wave sensor. The radio wave information includes identification information of the radio wave transmission source and position specifying information. The position specifying information is information that can be used to estimate the position of the radio wave transmission source. The collating unit 12 collates whether the received metadata matches the collation metadata. The received metadata is information included in the received radio wave information and is the identification information of the radio wave transmission source. The collation metadata is the identification information of a known radio wave transmission source. The estimating unit 14 estimates the position of the transmission source of the unknown radio wave based on the position specifying information included in the received radio wave information. The unknown radio wave is a received radio wave for which the received metadata does not match any of the collation metadata. The output unit 13 outputs unknown radio wave information. The unknown radio wave information is information regarding the position of the transmission source of the unknown radio wave.

[0032] In this way, the radio wave information output device 10 outputs information regarding the position of the transmission source of the unknown radio wave. Since information regarding the position of the transmission source of the unknown radio wave is output from the radio wave information output device 10, the investigator can more easily determine the possibility of the occurrence of radio wave interference by referring to the output information and take measures according to the position of the transmission source. As a result, the labor for investigating radio wave interference and identifying the interference source is reduced. Therefore, it becomes possible to output information for reducing the labor for investigating radio wave interference and identifying the interference source.

[0033] [Second Embodiment] Next, the radio wave information output device 20 in the second embodiment of the present invention will be described. Note that a specific example of the radio wave information output device 10 in the first embodiment is the radio wave information output device 20 in the second embodiment.

[0034] First, FIG. 3 shows a configuration example of a system including the radio wave information output device 20 of the present embodiment. The radio wave information output device 20 is connected to a radio wave sensor 50-i (i is an integer from 1 to N). Further, the radio wave information output device 20 is connected to a display means 60. The radio wave sensor 50-i and the radio wave information output device 20 are included in the monitoring system 40.

[0035] The radio wave sensor 50-i receives radio waves. Hereinafter, the radio waves received by the radio wave sensor 50-i are referred to as received radio waves. Further, the radio wave sensor 50-i outputs radio wave information about the received radio waves to the radio wave information output device 20.

[0036] The radio wave information is information about radio waves. The radio wave information includes identification information of the radio wave transmission source and position identification information.

[0037] The position identification information is information that can be used to identify the position of the transmission source. The position identification information may include, for example, direction information indicating the direction of arrival of the radio waves. The radio wave sensor 50-i can estimate the direction of arrival of the signal, for example, by using an antenna whose directivity can be controlled by beamforming or rotation. Further, the position identification information may include information used in radio wave emission position estimation methods such as the AOA (Angle of Arrival) method, the POA (Power of Arrival) method, and the TDOA (Time Difference of Arrival) method. Further, when the radio wave sensor 50-i can obtain the position information of the transmission source from the received radio waves, the position identification information may include the position information. The position of the radio wave transmission source can be obtained, for example, by using GNSS (Global Navigation Satellite System) or the like.

[0038] The radio wave sensor 50-i may be fixedly installed or may be movable. Further, the communication method for outputting radio wave information from the radio wave sensor 50-i to the radio wave information output device 20 may be wired or wireless.

[0039] The display means 60 is a man-machine interface such as a display as an output device. The display means 60 displays an image. In the present embodiment, it is assumed that the radio wave information output device 20 outputs unknown radio wave information, which is information regarding radio wave information, to the display means 60. However, the output destination of the unknown radio wave information is arbitrary. The radio wave information output device 20 may output the unknown radio wave information to an output destination other than the display means 60.

[0040] Next, FIG. 4 shows a configuration example of the radio wave information output device 20 of the present embodiment. The radio wave information output device 20 of the present embodiment includes a receiving unit 21, a collating unit 22, an output unit 23, and an estimating unit 24.

[0041] The receiving unit 21 receives radio wave information of the received radio wave from the radio wave sensor 50-i. The received radio wave is the radio wave received by the radio wave sensor 50-i. The radio wave information is information regarding the radio wave. The radio wave information includes identification information of the radio wave source and position specifying information. Hereinafter, the identification information of the radio wave source is referred to as radio wave identification information. Further, the radio wave identification information included in the radio wave information received by the receiving unit 21 is hereinafter referred to as received metadata.

[0042] The radio wave identification information is information that can identify the individual of the source. The radio wave identification information may include, for example, IMEI (International Mobile Equipment Identity), IMSI (International Mobile Subscriber Identity), MAC (Media Access Control) address, etc. When the source is a drone, the radio wave identification information may include a remote ID (identification), which is the identification information of the drone.

[0043] Also, when the transmission source is a base station, the radio wave identification information may include a PCI (Physical Cell Identifier). Further, the radio wave identification information may include the number of the beamforming area included in an SSB (SS (Synchronization Signal) / PBCH (Physical Broadcast Channel) Block). Although the PCI or the number of the beamforming area cannot identify the individual of the transmission source alone, it is information that can narrow down the corresponding individual when combined with other information. For example, when the radio wave identification information includes the PCI and the number of the beamforming area, the corresponding transmission source is almost uniquely identified.

[0044] Also, the radio wave identification information may include information based on the location information of the transmission source. For example, when the transmission source is fixedly installed, the location information of the transmission source may be used as the radio wave identification information. Also, when the transmission source moves on the same route, the movement route of the transmission source may be used as the radio wave identification information.

[0045] The radio wave sensor 50-i can obtain the location information of the transmission source from the radio wave transmitted by the transmission source. For example, the transmission source acquires its own location using GNSS. Then, the radio wave sensor 50-i can obtain the location information of the transmission source from the signal including the location information by monitoring the signal transmitted by the transmission source.

[0046] Also, the radio wave identification information may include information regarding the frequency of the radio wave. For example, the radio wave identification information may include information such as SS (Synchronization Signal) ref. Although there are many transmission sources using the same frequency on the field, when the frequency information is combined with other information, for example, the location information, the candidates of the individual of the transmission source may be narrowed down.

[0047] In addition to the radio wave identification information, the radio wave information may include information such as the frequency, modulation method, and received signal level in the radio wave sensor 50-i for the radio wave transmitted by the transmission source. For example, the radio wave information may include information such as SS-RSRQ (Reference Signal Received Quality).

[0048] The collation unit 22 collates whether the received metadata and the collation metadata match. The received metadata is the radio wave identification information included in the radio wave information received by the receiving unit 21. The collation metadata is the radio wave identification information of the radio wave output from a known transmission source. The known transmission source is a properly installed radio base station, a legitimate wireless terminal, or the like. The collation metadata is stored in a storage unit (not shown). Note that the storage unit may be inside or outside the radio wave information output device 20.

[0049] When the radio wave identification information includes two or more types of metadata, the collation unit 22 makes a determination as to whether the received metadata and the collation metadata match according to a predetermined collation condition. The collation condition is a condition related to the metadata used as the radio wave identification information. The collation condition is a condition that is satisfied when the collation unit 22 determines that the received metadata and the collation metadata match. The collation condition is set to an arbitrary condition according to the metadata used as the radio wave identification information.

[0050] The collation condition may be, for example, that either the first condition or the second condition is satisfied. The first condition may be, for example, that any one of the metadata that can uniquely identify an individual, such as IMEI, matches. The second condition may be, for example, that for metadata that cannot uniquely identify an individual alone, any of the metadata included in a predetermined combination of metadata matches. For example, the second condition may be that both the PCI and the number of the beamforming area match.

[0051] Received radio waves for which the received metadata does not match any of the collation metadata are radio waves for which no match is found in collation with known radio wave identification information. That is, received radio waves for which the received metadata does not match any of the collation metadata are unknown received radio waves. Received radio waves for which the received metadata does not match any of the collation metadata may hereinafter be referred to as unknown radio waves. Note that unknown radio waves include radio waves transmitted from an illegal transmission source such as an illegal base station or terminal, and radio waves for which the radio wave identification information has become abnormal due to some defect even if they are radio waves transmitted from a legitimate transmission source.

[0052] The estimation unit 24 estimates the position of the transmission source of the unknown radio wave. The method of estimating the position will be described later.

[0053] The output unit 23 outputs unknown radio wave information. The unknown radio wave information is information regarding the position of the transmission source of a received radio wave (unknown radio wave) for which the received metadata does not match any of the collation metadata.

[0054] As described above, in this embodiment, the output unit 23 outputs information regarding the position of the transmission source of the unknown radio wave as unknown radio wave information. Therefore, the user who receives the information can easily grasp the presence of radio waves transmitted from an illegal transmission source or abnormal radio waves and information regarding their positions. As a result, it becomes easy to implement countermeasures against unknown radio waves.

[0055] The output unit 23 may suppress the output of information regarding known received radio waves. Suppressing the output of information regarding known received radio waves can reduce the amount of information from the radio wave information output device 20 to the output destination and also reduce the communication load. Also, for the user, it becomes easier to select information.

[0056] Also, the output unit 23 may output known radio wave information, which is information regarding known received radio waves, separately from the unknown radio wave information. Known received radio waves are received radio waves for which the received metadata matches any of the collation metadata.

[0057] In this embodiment, the output unit 23 outputs the unknown radio wave information to the display means 60. Also, in this embodiment, the unknown radio wave information is image information for causing the display means 60 to display an image. That is, the output unit 23 causes the display means 60 to display an image by outputting the unknown radio wave information to the display means 60.

[0058] Next, a specific example of the image that the output unit 23 causes the display means 60 to display will be described.

[0059] For example, the image may include a screen item indicating the transmission source at the position of the transmission source on the map. The radio wave in which the screen item indicating the transmission source is included in the image is an unknown radio wave. That is, the image includes a screen item indicating the transmission source for the received radio wave whose received metadata does not match any of the collation metadata.

[0060] Also, the position of the transmission source is often estimated not at a pinpoint but within a range having a certain width. Therefore, the screen item indicating the transmission source may be displayed in a size indicating the range where the transmission source is estimated to exist.

[0061] Also, the image may further display at least a part of the radio wave information for each radio wave. For example, the image may display the received metadata in association with the screen item indicating the transmission source. FIG. 5 is a diagram showing an example of the display image. In the case of the example of FIG. 5, the circle is a screen item indicating the transmission source. In this way, in the image, a screen item indicating the transmission source is arranged at the position of the transmission source on the map. Also, in the case of the example of FIG. 5, the size of the screen item indicates the range where the transmission source is estimated to exist. Also, in the image, the type of radio wave, the used frequency band, the PCI, etc. are displayed in association with the screen item indicating the transmission source.

[0062] Further, the output unit 23 may output the unknown radio wave information to an output destination other than the display means 60. For example, the unknown radio wave information may be data including information regarding the position of the source of the unknown radio wave. Further, the unknown radio wave information may include information regarding at least a part of the radio wave information of the unknown radio wave.

[0063] For example, the output unit 23 may output the unknown radio wave information to an alarm management device that manages an alarm device that performs an alarm broadcast. The alarm device performs an alarm broadcast by, for example, specific radio or disaster prevention radio.

[0064] The storage unit stores, for each alarm device, identification information of the alarm device, information on the position of the alarm device, and information on the notification destination of the alarm management device that manages the alarm device. Note that the notification destination in this case is the output destination of the unknown radio wave information output from the output unit 23 to the alarm management device. The output unit 23 refers to the information on the position of the alarm device and identifies an alarm device existing within a predetermined distance from the source of the unknown radio wave. Further, the output unit 23 identifies an alarm management device that manages an alarm device existing within a predetermined distance from the source of the unknown radio wave. Then, the output unit 23 outputs the unknown radio wave information to the notification destination of the identified alarm management device. The unknown radio wave information in this case includes the identification information of the alarm device existing within a predetermined distance from the source of the unknown radio wave.

[0065] In this way, the alarm management device that has received the unknown radio wave information can instruct the alarm device existing near the source of the unknown radio wave to perform an alarm broadcast. Thereby, a warning can be given to the source of the unknown radio wave by using the alarm device existing near the source of the unknown radio wave.

[0066] Further, for example, the output unit 23 may notify the existence of the unknown radio wave to a predetermined notification destination such as a communication carrier by outputting the unknown radio wave information to the predetermined notification destination.

[0067] For example, the memory unit stores in advance, for each telecommunications carrier, the information of the notification destination and the information of the frequency band used in the service provided by the telecommunications carrier. Note that the notification destination in this case is the output destination of the unknown radio wave information output from the output unit 23 to the telecommunications carrier. The output unit 23 refers to the information of the frequency band used in the service provided by the telecommunications carrier, and identifies the telecommunications carrier whose frequency used by the unknown radio wave is included in the frequency band used in the provided service. Then, the output unit 23 outputs the unknown radio wave information to the notification destination of the identified telecommunications carrier. The unknown radio wave whose information is included in the unknown radio wave information in this case is an unknown radio wave using a frequency included in the frequency band used in the service provided by the identified telecommunications carrier. Further, the unknown radio wave information may include at least a part of the radio wave information of the unknown radio wave using a frequency included in the frequency band used in the service provided by the telecommunications carrier. For example, the unknown radio wave information may include information such as the frequency used by the unknown radio wave.

[0068] In this way, it becomes possible to provide the telecommunications carrier with the information of the position of the source of the unknown radio wave that may be an interfering wave to the service provided by the telecommunications carrier. Then, the telecommunications carrier can grasp the possibility of radio wave interference caused by the unknown radio wave and take countermeasures.

[0069] Further, for example, the output unit 23 may notify the existence of the unknown radio wave to the notification destination by outputting the unknown radio wave information to the notification destination according to the position of the source of the unknown radio wave.

[0070] For example, the memory unit stores in advance the correspondence between the information of the notification destination and the information of the area. The output unit 23 refers to the correspondence between the information of the notification destination and the information of the area, and identifies the notification destinations whose positions of the sources of the unknown radio waves are included in the area. Then, the output unit 23 outputs the unknown radio wave information to the identified notification destinations. The unknown radio waves whose information is included in the unknown radio wave information in this case are the unknown radio waves whose source positions are included in the area associated with the notification destination. Also, the unknown radio wave information may include at least a part of the radio wave information of the unknown radio waves. For example, the unknown radio wave information may include information on the frequency used by the unknown radio wave, information on the position of the source of the unknown radio wave, and the like.

[0071] In this way, it becomes possible to provide the information of the unknown radio waves existing within the area associated with the notification destination to the notification destination. Then, the notification destination can grasp the possibility of radio wave interference caused by the unknown radio waves and take countermeasures. For example, it becomes possible to notify the airport administrator or the like that the unknown radio waves exist within the airport.

[0072] Next, a method for estimating the position of the source of the unknown radio waves will be described. Any method can be used for the method of estimating the position of the source. For the estimation of the position of the source, for example, radio wave emission position estimation methods such as the AOA method, the POA method, and the TDOA method can be used. Also, when the radio wave information received by the receiving unit 21 includes the position information of the source acquired by GNSS, that position information can be used.

[0073] An example of the method for estimating the position of the source will be described. In the case of this example, the radio wave information received by the receiving unit 21 includes the frequency of the received signal, the modulation method, and the position identification information. Also, the position identification information includes direction information indicating the direction of arrival of the radio wave.

[0074] First, the estimation unit 24 groups the radio wave sensors 50-1 to 50-N into sensors that receive radio waves from the same transmission source. The groups generated by the grouping are groups of radio wave sensors that are estimated to receive the same radio waves. Since one radio wave sensor can receive one or two or more radio waves, it may belong to a plurality of groups. For the estimation unit 24, for a certain radio wave sensor, other radio wave sensors that satisfy both of the following two conditions are regarded as sensors that receive radio waves from the same transmission source. The first condition is that the frequencies and modulation methods of the received radio waves are the same. The second condition is that the distance between the radio wave sensors is within a predetermined range. Note that the storage unit stores information on the positions of the respective radio wave sensors 50-i.

[0075] Next, for each group, the estimation unit 24 estimates the intersection of the straight lines extended from the radio wave sensors in the direction of arrival of the radio waves as the position of the transmission source. If the intersection is not determined at one location, the estimation unit 24 estimates, for example, a region including two or more intersections as the position of the transmission source. For example, the estimation unit 24 may estimate the minimum enclosing circle of two or more intersections as the region estimated to be the position of the transmission source. When there is one radio wave sensor included in the group, the estimation unit 24 may not estimate the position of the transmission source, or may estimate the position of the transmission source by any method. For example, the estimation unit 24 may estimate a region including a straight line of a predetermined length extended from the position of the radio wave sensor in the direction of arrival of the radio waves as the region estimated to be the position of the transmission source.

[0076] Further, the estimation unit 24 may use the reliability information of the arrival direction of the radio wave for estimating the position of the transmission source. For example, when estimating the arrival direction of the radio wave, the radio wave sensor 50-i further calculates the reliability of the estimated arrival direction. For example, the reliability may be a value that increases as the received signal level increases. In this case, the radio wave information transmitted from the radio wave sensor 50-i to the radio wave information output device 20 includes position identification information including direction information and reliability information. Then, when there are a plurality of radio wave sensors belonging to the group and a plurality of intersection points, the estimation unit 24 may estimate the position of the transmission source without using the direction information of the received radio wave whose reliability is lower than a predetermined reference.

[0077] Next, an example of the operation flow of the radio wave information output device 20 of the present embodiment will be described. FIG. 6 shows an example of the operation flow of the radio wave information output device 20 of the present embodiment.

[0078] The receiving unit 21 receives radio wave information from the radio wave sensor 50-i (step S201). In the present embodiment, the radio wave information is transmitted from the radio wave sensor 50-i at regular intervals.

[0079] The collating unit 22 collates the received metadata and the collation metadata (step S202). In the present embodiment, the collation is performed at regular intervals.

[0080] The estimation unit 24 estimates the position of the transmission source of the received radio wave (unknown radio wave) whose received metadata does not match any of the collation metadata (step S203). Note that when the position information of the transmission source obtained by using GNSS or the like is included in the position identification information, the estimation unit 24 may not estimate the position of the transmission source.

[0081] Then, the output unit 23 outputs the unknown radio wave information (step S204). In the present embodiment, the output unit 23 outputs the unknown radio wave information at regular intervals. The output unit 23 may output the unknown radio wave information at arbitrary timings instead of at regular intervals. For example, the output unit 23 may output the unknown radio wave information only when an unknown radio wave exists. Also, for example, the output unit 23 may output unknown radio wave information indicating that no unknown radio wave exists when no unknown radio wave exists. Further, the output unit 23 may output the unknown radio wave information when requested by the device at the output destination of the unknown radio wave information.

[0082] As described above, in the second embodiment of the present invention, the radio wave information output device 20 includes a reception unit 21, a collation unit 22, an output unit 23, and an estimation unit 24. The reception unit 21 receives radio wave information about the received radio wave. The received radio wave is the radio wave received by the radio wave sensor. The radio wave information includes identification information of the radio wave source and position identification information. The position identification information is information that can be used to estimate the position of the radio wave source. The collation unit 22 collates whether the received metadata matches the collation metadata. The received metadata is information included in the received radio wave information and is the identification information of the radio wave source. The collation metadata is the identification information of a known radio wave source. The estimation unit 24 estimates the position of the unknown radio wave source based on the position identification information included in the received radio wave information. The unknown radio wave is a received radio wave whose received metadata does not match any of the collation metadata. The output unit 23 outputs the unknown radio wave information. The unknown radio wave information is information regarding the position of the unknown radio wave source.

[0083] In this way, the radio wave information output device 20 outputs information regarding the position of the unknown radio wave source. Since the information regarding the position of the unknown radio wave source is output from the radio wave information output device 20, the investigator can more easily determine the possibility of the occurrence of radio wave interference by referring to the output information and take measures according to the position of the source. As a result, the labor for investigating radio wave interference and identifying the interference source is reduced. Therefore, it becomes possible to output information for reducing the labor for investigating radio wave interference and identifying the interference source.

[0084] Also, in the present embodiment, the location identification information includes information on the direction of arrival of radio waves. Thereby, the estimation unit 24 can estimate the position of the radio wave transmission source based on the direction of arrival of the radio waves.

[0085] Also, in the present embodiment, the output unit 23 identifies a communication carrier that uses a frequency included in the frequency band used by an unknown radio wave in the frequency band used by the service provided by the communication carrier. Further, the output unit 23 outputs the unknown radio wave information to the notification destination of the identified communication carrier. The unknown radio wave information includes information on the position of the transmission source of the unknown radio wave that uses a frequency included in the frequency band used by the service provided by the identified communication carrier. Thereby, it becomes possible to provide the communication carrier with information on the position of the transmission source of the unknown radio wave that may be an interfering wave to the service provided by the communication carrier. Then, the communication carrier can grasp the possibility that radio wave interference by the unknown radio wave has occurred and take countermeasures.

[0086] Also, in the present embodiment, the output unit 23 outputs the unknown radio wave information to a display means for displaying an image. Further, the unknown radio wave information is image information for causing the display means to display an image. The image includes a screen item indicating the transmission source at the position of the transmission source of the unknown radio wave on the map. Thereby, an investigator who has confirmed the display can easily grasp the position of the transmission source of the unknown radio wave, so that the labor of investigating radio wave interference and identifying the interference source can be reduced.

[0087] Also, in the present embodiment, the output unit 23 identifies an alarm device existing within a predetermined distance from the transmission source of the unknown radio wave. Further, the output unit 23 outputs the unknown radio wave information to the notification destination of an alarm management device that manages the identified alarm device. The unknown radio wave information includes identification information of an alarm device existing within a predetermined distance from the transmission source of the unknown radio wave. The alarm device performs an alarm broadcast. Thereby, the alarm management device that has received the unknown radio wave information can instruct the alarm device existing near the transmission source of the unknown radio wave to perform an alarm broadcast. Thereby, a warning can be given to the transmission source of the unknown radio wave by using the alarm device existing near the transmission source of the unknown radio wave.

[0088] Also, in the present embodiment, the output unit 23 refers to the correspondence relationship between the information of the notification destination and the information of the area, identifies the notification destination whose location of the source of the unknown radio wave is included in the area, and outputs the unknown radio wave information to the identified notification destination. Thereby, it becomes possible to provide the information of the unknown radio wave existing within the area associated with the notification destination to the notification destination. Then, the notification destination can grasp the possibility that radio wave interference is occurring due to the unknown radio wave and take countermeasures.
