As the time, for example, the time when the corresponding information is acquired by the information acquisition unit 231 may be used, or the time when the information acquisition unit 231 stores the corresponding information in the storage unit 214 may be used. good. Further, as the time, for example, the time measured by the information processing device 22 may be used, or the time detected from the outside by the information processing device 22 may be used.

In the present embodiment, the beacon transmitter information 1011 is set in advance in the information processing device 22 and stored in the storage unit 214. Beacon transmitter information 1011 may be set by human operation, for example.

The beacon transmitter information 1011 is information in which the identification information (ID) of the beacon transmitter, the height of the position where the beacon transmitter is installed, and the position are associated with each other. In the present embodiment, the information is stored for each of the beacon transmitters B1 to B5, B11 to B13, B21 to B25, B31 to B33, and B41 to B45.
In the example of FIG. 3, a numerical value is used as the ID of the beacon transmitter, but arbitrary information may be used. Further, although the coordinates (X, Y, Z) in the XYZ Cartesian coordinate system are used as the positions, arbitrary information may be used. Further, although a numerical value is used as the height, arbitrary information may be used. Further, the unit of height may be arbitrary, for example, meters [m].
Further, as the height information, for example, information on other items corresponding to the height may be used, and in the present embodiment, information on atmospheric pressure (information such as atmospheric pressure value) may be used. ..

In the example of FIG. 3, for example, for a beacon transmitter whose ID of the beacon transmitter is "0001", the height of the position where the beacon transmitter is installed is "5", and the position of the beacon transmitter is It is stored that it is (X1, Y1, Z1). In the example of FIG. 3, the columns corresponding to the IDs of other beacon transmitters are also described in the same manner.
In the present embodiment, for example, when the respective beacon transmitters B1 to B5, B11 to B13, B21 to B25, B31 to B33, and B41 to B45 shown in FIG. 1 are installed on the steel tower 11, the installation positions thereof. Beacon transmitter information 1011 suitable for (including height) is stored in the storage unit 214.
Here, in the example of FIG. 3, an example of distinguishing between the height and the position is shown. However, for example, the height column is omitted, and the Z of the positions (X, Y, Z) in the information processing apparatus 22 is omitted. The value of may be regarded as the height and used.

As a correspondence between the example of FIG. 1 and the example of FIG. 3, for example, the heights of the beacon transmitters B1 to B5 are "5", the heights of the beacon transmitters B11 to B13 are "10", and the beacons. Assuming that the heights of the transmitters B21 to B25 are "15", the beacon transmitter whose ID of the beacon transmitter is "0001" is one of the beacon transmitters B1 to B5, and is of the beacon transmitter. Each of the beacon transmitters having the ID "0002" or "0003" is one of the beacon transmitters B11 to B13, and the beacon transmitter having the beacon transmitter ID "0004" is the beacon transmitter B21. ~ B25.
As the correspondence between the example of FIG. 1 and the example of FIG. 3, any other correspondence may be used.

FIG. 4 is a diagram showing an example of beacon reception information 1021 according to an embodiment of the present invention.
The beacon reception information 1021 is information related to the beacon signal received by the beacon receiver 32, and in the present embodiment, the beacon reception information 1021 is received by the communication unit 213 and stored in the storage unit 214.

The beacon reception information 1021 includes the time, the identification information (ID) of the beacon transmitter that communicates (received in this embodiment) the beacon signal by the beacon receiver 32, and the reception strength (reception strength) of the beacon signal. It is the information corresponding to. The identification information of the beacon transmitter that communicated (received in this embodiment) the beacon signal by the beacon receiver 32 was included in the beacon signal for one or more beacon signals received by the beacon receiver 32. Beacon transmitter identification information.
In the example of FIG. 4, a numerical value is used as the ID of the beacon transmitter, but arbitrary information may be used. Further, as the time, a two-digit hour, a two-digit minute, and a two-digit second are used, but arbitrary information may be used. Further, although a numerical value is used as the intensity, arbitrary information may be used. Further, the unit of strength may be arbitrary, for example, decibel [dB].
For example, the time information may include information such as year, month, and day.
Further, for example, when a configuration in which the intensity information is not used is used, the beacon reception information 1021 may not include the intensity information.

In the example of FIG. 4, for example, the beacon receiver 32 communicates the beacon signal (received in the present embodiment) at the timing corresponding to the time when the time is "14:15:20" (14:15:20). It is stored that the ID of each beacon transmitter is "0001, 0002, 0003" and the strength of the beacon signal from each beacon transmitter is "10, 10, 15". Here, in the example of FIG. 4, in the ID column and the strength column of the communicated beacon transmitter, if there is information about two or more different beacon transmitters, they are separated by commas (,) for convenience of explanation. There is. That is, when the ID of the communicated beacon transmitter is "0001,0002,0003" and the intensity is "10,10,15", the IDs of the beacon transmitters are "0001", "0002", "0003". The intensity of each of the beacon transmitters of "10", "10", and "15" is shown. In the example of FIG. 4, the columns corresponding to other times are also described in the same manner.

Normally, when the beacon signal transmitted from a certain beacon transmitter is received by the beacon receiver 32, when there is no obstacle such as a wall between the beacon transmitter and the beacon receiver, the beacon is concerned. The smaller the distance between the transmitter and the beacon receiver (that is, the closer they are), the greater the intensity of reception. Further, when there is the blocking object, the reception intensity is reduced by the blocking object.

FIG. 5 is a diagram showing an example of height detection information 1031 according to an embodiment of the present invention.
The height detection information 1031 is information regarding the height of the moving body 12 obtained based on the information detected by the altitude detector 33 and the information detected by the altitude reference detector 21, and in the present embodiment, the information. It is generated by the acquisition unit 231 and stored in the storage unit 214.

The height detection information 1031 is information in which the time is associated with the information (height) detected as the height of the moving body 12.
In the example of FIG. 5, the time notation is the same as that of the example of FIG.
Further, in the example of FIG. 5, the height notation is the same as that of the example of FIG.

In the example of FIG. 5, it is memorized that the height of the moving body 12 is “5” at the timing corresponding to, for example, when the time is “14:15:20” (14:15:20). ing. In the example of FIG. 5, the columns corresponding to other times are also described in the same manner.

Here, in the present embodiment, the beacon reception information 1021 shown in FIG. 4 and the height detection information 1031 shown in FIG. 5 are set so as to include information corresponding to the same time. In the example of FIG. 4 and the example of FIG. 5, the beacon reception information 1021 and the height detection correspond to the times such as "14:15:20", "14:16:30", and "14:17:40". Information 1031 and each information are stored.
In addition, in the example of FIG. 4 and the example of FIG. 5, as an example for explanation, the case where the beacon reception information 1021 and the height detection information 1031 are acquired every 70 seconds is shown. Any time interval, such as every second, may be used.
Further, in the mobile information processing system 1 according to the present embodiment, the beacon reception information 1021 shown in FIG. 4 and the height detection information 1031 shown in FIG. 5 are stored as separate information (for example, a table). , As another configuration example, a configuration for storing the information in which these are summarized may be used.

The communication partner identification unit 232 is based on the beacon transmitter information 1011 and the beacon reception information 1021 and the height detection information 1031, and the communication partner identification unit 232 identifies the beacon transmitter associated with the information of each time in the beacon reception information 1021 (FIG. From the "ID of the communicated beacon transmitter" in the example of 4, the identification information of the beacon transmitter that is determined to be appropriate with respect to the height information is specified (selected).
In the present embodiment, the communication partner identification unit 232 refers to the identification information (example of FIG. 4) of one or more beacon transmitters associated with the information at each time in the beacon reception information 1021. The height of the moving body 12 (example of FIG. 5) is appropriate for the height of the beacon transmitters B1 to B5, B11 to B13, B21 to B25, B31 to B33, and B41 to B45 (example of FIG. 3). Identify what is determined to be.

A specific example is shown.
In the example of FIG. 4, the time information “14:15:20” is associated with the ID “0001,0002,0003” of the communicated beacon transmitter. Further, in the example of FIG. 5, the height (height of the moving body 12) “5” is associated with the time information “14:15:20”.
Then, the communication partner identification unit 232 sets the time information “14:15:20” to a height “5” from the ID “0001,0002,0003” of the communicated beacon transmitter in the example of FIG. On the other hand, the ID of the beacon transmitter installed at a reasonable height (that is, the ID of the beacon transmitter associated with the information at a reasonable height) is specified. In this case, the communication partner identification unit 232 refers to the beacon transmitter information 1011 and refers to, for example, one beacon transmitter whose height (installed height) matches the height "5". ID "0001" is determined to be appropriate and specified. The heights of the IDs "0002" and "0003" of the other two beacon transmitters are both "10", and the communication partner identification unit 232 is determined to be inappropriate and adopted (selected). )do not.

Further, the communication partner identification unit 232 refers to the time information "14:16:30" with respect to the height "5" from the IDs "0001,0002" of the beacon transmitter that communicated in the example of FIG. Identify the ID "0001" of the beacon transmitter installed at a reasonable height.
Further, the communication partner identification unit 232 has a height of "10, 0002, 0003, 0004" from the IDs "0001, 0002, 0003, 0004" of the beacon transmitter that communicated in the example of FIG. 4 for the time information "14:17:40". The IDs "0002" and "0003" of the beacon transmitters installed at appropriate heights are specified. In this way, the communication partner identification unit 232 may specify (select) the IDs of two or more beacon transmitters.
Further, the communication partner identification unit 232 sets the time information “14:18:50” to a height “15” from the ID “0002,0003,0004” of the communicated beacon transmitter in the example of FIG. On the other hand, the ID "0004" of the beacon transmitter installed at an appropriate height is specified.

In this way, when the beacon transmitter determined to be appropriate in terms of height is specified by the communication partner identification unit 232, for example, the height of the beacon receiver 32 in the moving body 12 is significantly different from the height of the moving body 12. Even when a beacon signal from a beacon transmitter installed at (inappropriate height) is also received, such a beacon transmitter can be excluded. Therefore, the communication partner identification unit 232 identifies the communication partner (in this embodiment, the beacon transmitter determined to be appropriate in terms of height), and the subsequent processing (processing based on the specified beacon transmitter) is performed. When this is performed, the accuracy of the subsequent processing can be improved as compared with the case where the subsequent processing (processing based on a beacon transmitter that is not valid in terms of height) is performed without specifying such a communication partner. ..

Here, in the present embodiment, the beacon reception information 1021 in the example of FIG. 4 and the height detection information 1031 in the example of FIG. 5 have time information attached to each information. Then, in the present embodiment, the communication partner identification unit 232 uses the beacon reception information 1021 and the height detection information 1031 as information corresponding to the information at the same time (information on the ID of the communicated beacon transmitter, information on the height). ) Is used to identify the communication partner.
As another configuration example, the beacon reception information 1021 in the example of FIG. 4 and the height detection information 1031 in the example of FIG. 5 may be configured in which the information of the attached time is not aligned. In this case, the communication partner identification unit 232 uses the beacon reception information 1021 and the height detection information 1031 as information corresponding to information at the same time or close time (information on the ID of the communicated beacon transmitter, information on the height). To identify the communication partner. Here, an arbitrary condition is used as the "near time" condition for associating the beacon reception information 1021 with the height detection information 1031 (that is, the near time condition for combining these two pieces of information). May be done. For example, the condition of "closest time" may be used as the condition of "closest time", or "the closest time (in this case) in which the time difference is equal to or less than a predetermined threshold value (positive value)". , It is possible that there is no corresponding combination) ”may be used.

Further, in the example of FIG. 3 and the example of FIG. 5, in order to simplify the explanation, the height of the moving body 12 is used by using the value for each fixed interval (“5” in this example) as the height information. We used the condition that it is valid when the information and the height information of the beacon transmitter match, and it is judged that it is not valid when they do not match.

As another configuration example, the height information of the moving body 12 may not always match the height information of the beacon transmitters B1 to B5, B11 to B13, B21 to B25, B31 to B33, and B41 to B45. The configuration may be used. In this configuration, the communication partner identification unit 232 sets the beacon transmitter (beacon transmitter ID) installed at or near the height of the mobile body 12 at or near the height. Determine that the height is appropriate and identify it. Here, an arbitrary condition is used as the "near height" condition (that is, the near height condition for determining that the height is valid) when it is determined that the height is valid. You may.

As an example, the condition of "closest height" may be used as the condition of "closest height". Under this condition, it is determined that the ID of one beacon transmitter or the ID of two or more beacon transmitters installed at the same height is appropriate for the height of a certain mobile body 12. NS.
As another example, as a condition of "close height", "the height difference is less than or equal to a predetermined threshold value (positive value), and the closest height (in this case, there may be no corresponding combination). ) ”Is used. Under this condition, it is determined that the ID of one beacon transmitter or the ID of two or more beacon transmitters installed at the same height is appropriate for the height of a certain mobile body 12. It may also be determined that the corresponding beacon transmitter does not exist.

As another example, as the condition of "close height", the condition "the difference in height is equal to or less than a predetermined threshold value (positive value) (in this case, there may be no corresponding combination)" is used. May be done. Under this condition, it may be determined that the IDs of one or more beacon transmitters are appropriate for the height of a certain mobile body 12, and it is determined that the corresponding beacon transmitter does not exist. It is possible.
Under this condition, as a further configuration example, when the communication partner identification unit 232 determines that the corresponding beacon transmitter does not exist, it is said that "the height difference is equal to or less than a predetermined threshold value (positive value)". The "predetermined threshold value (positive value)" in the condition may be increased by a predetermined amount, and the process of identifying the beacon transmitter determined to be appropriate in terms of height may be performed again. The communication partner identification unit 232 repeats increasing the "predetermined threshold value (positive value)" by a predetermined amount once or twice or more in this way to obtain the ID of at least one beacon transmitter. Can be identified.

Further, the communication partner identification unit 232 may specify (select) a communication partner based on not only information on the height but also other information.
For example, the communication partner identification unit 232 may specify (select) the communication partner based on the strength information shown in FIG.
As an example, the communication partner identification unit 232 determines and identifies a beacon transmitter (beacon transmitter ID) whose strength is equal to or higher than a predetermined threshold value based on the strength information shown in FIG. You may (select). Any value may be used as the predetermined threshold value.

When the communication partner identification unit 232 makes a determination based on both the height information and the strength information, for example, the communication partner identification unit 232 makes a determination based on the height information and then makes a determination based on the strength information. Or the determination may be made based on the strength information and then the determination based on the height information, or these two pieces of information may be collectively determined.
Further, as another example, when the communication partner identification unit 232 makes a determination based on both the height information and the strength information, for example, as a result of making the determination based on the height information, 2 When more than one beacon transmitter is identified (selected), the determination may be made based on the intensity information.
Here, the communication partner identification unit 232 is, for example, a beacon transmitter (beacon transmitter) when there is no beacon transmitter that satisfies the condition relating to the strength (for example, the condition that the strength is equal to or higher than a predetermined threshold value). The result may be that the beacon transmitter (ID) is not specified (selected), or the beacon transmitter (ID of the beacon transmitter) that does not satisfy the condition but has the highest intensity may be specified (selected).

In this way, when the communication partner identification unit 232 identifies the beacon transmitter that is determined to be appropriate in terms of intensity, for example, when a beacon signal from a beacon transmitter with low reception intensity (inappropriate intensity) is also received. Also, such a beacon transmitter can be excluded. Therefore, regarding the strength, when the communication partner is specified by the communication partner identification unit 232 and the subsequent processing (processing based on the specified beacon transmitter) is performed, the subsequent processing is performed without specifying such a communication partner. The accuracy of the subsequent processing can be improved as compared with the case where (processing based on the beacon transmitter which is not appropriate in terms of strength) is performed.

The position specifying unit 233 specifies the position information of the mobile body 12 based on the communication partner (beacon transmitter in the present embodiment) specified (selected) by the communication partner specifying unit 232. The position specifying unit 233 stores information (for example, table information) in which the information for identifying the moving body 12, the time information, and the position information of the moving body 12 specified for the time are associated with each other. Store in unit 214.

Here, any method may be used as a method for specifying the position information of the moving body 12.
For example, when one beacon transmitter is specified by the communication partner identification unit 232, the position identification unit 233 moves the position of the beacon transmitter with reference to the beacon transmitter information 1011 shown in FIG. It may be specified as the position of the body 12. Further, the position specifying unit 233 may specify the position where the position of the beacon transmitter is corrected as the position of the moving body 12 based on the strength shown in FIG. 4 (strength corresponding to the beacon transmitter). good.

For example, when two or more different beacon transmitters are specified by the communication partner identification unit 232, the position identification unit 233 refers to the beacon transmitter information 1011 shown in FIG. 3 and transmits these two or more beacons. The position calculated using the position of the machine may be specified as the position of the moving body 12. Here, as a method of calculating one position (position of the moving body 12) using the positions of two or more beacon transmitters, any method may be used, for example, an average or the like is used. You may. Further, the position specifying unit 233 may calculate the position (position of the moving body 12) based on the strength shown in FIG. 4 (strength corresponding to each of the two or more beacon transmitters). Here, as a method of calculating one position (position of the moving body 12) using the positions and intensities of two or more beacon transmitters, any method may be used, for example, weighting by intensity. The average of the above may be used.
For example, when three or more different beacon transmitters are specified by the communication partner identification unit 232, the position identification unit 233 refers to the beacon transmitter information 1011 shown in FIG. 3, and three of them. The position calculated by the triangulation technique using the positions of the individual beacon transmitters may be specified as the position of the moving body 12.

Further, when the beacon transmitter is not specified by the communication partner specifying unit 232, the position specifying unit 233 does not have to specify the position of the moving body 12, for example, or the moving body 12 specified last time. The position based on the position may be specified as the position of the moving body 12 this time. Here, as the position based on the position of the moving body 12 specified last time, for example, the position of the moving body 12 specified last time may be the same, or the position of the moving body 12 specified last time may be the same. It may be a position estimated based on (for example, a position after the movement estimated from the previous position).

The locus specifying unit 234 specifies the information on the movement locus of the moving body 12 based on the position information of the moving body 12 specified by the position specifying unit 233.
In the present embodiment, the locus specifying unit 234 provides information on the locus of the moving body 12 by associating information at a plurality of times with information on the position of the moving body 12 at each time. Identify as information. That is, in the present embodiment, the state of the position that changes according to the advance of the time (the position that does not change when the moving body 12 is stopped) is used as the locus.

The display control unit 235 controls to display predetermined information. This display is performed, for example, on the screen of the display unit included in the output unit 212.
The predetermined information may be arbitrary information, and may include, for example, information about the beacon transmitter specified by the communication partner identification unit 232, or information used to perform this identification. Alternatively, it may include information about the position of the moving body 12 specified by the position specifying unit 233, or information used to perform this identification, or the locus of the moving body 12 specified by the locus specifying unit 234. May include information about, or information used to make this identification.

By specifying (selecting), beacon transmitters that are not valid in terms of height (for example, beacon transmitters installed at a height significantly different from the height of the moving body 12) are excluded, and beacons that are valid in terms of height are excluded. The transmitters (for example, the beacon transmitters installed at the same height as the moving body 12) are narrowed down. As a result, in the mobile information processing system 1 according to the present embodiment, for example, due to the influence of the radio wave diffusion effect or the like, the beacon receiver 32 of the mobile body 12 has a beacon signal from a nearby beacon transmitter that is appropriate in terms of height.
