  FIG. 1 shows a configuration of an embodiment of an antenna direction adjusting apparatus according to the present invention. Here, it is assumed that a temporary parabolic antenna is installed in an emergency such as a disaster and the direction of the parabolic antenna is adjusted.

  In FIG. 1, the temporary parabolic antenna 10 includes a permanent parabolic antenna 20 that faces the temporary parabolic antenna 10. The permanent parabolic antenna 20 is installed on the roof of the base station building (communication establishment building) 21. The parabolic antenna 20 is mounted on a horizontal / vertical direction adjuster 22 and the direction of the parabolic antenna 20 can be changed. A plurality of (for example, three or more) heating elements 23 are arranged at or near the outline of the parabolic antenna 20. As the heating element 23, an electric heating coil, a panel-like or sheet-like heating element, or the like can be used.

  Before establishing a radio link between the temporary parabolic antenna 10 and the permanent parabolic antenna 20 facing the temporary parabolic antenna 10, for example, a radio 31 used for disaster prevention radio communication so that communication using a control signal or the like can be performed by another means. , 32 and the radio line 33 are used.

  The temporary parabolic antenna 10 has a GPS device 11 and receives the radio wave from the GPS satellite 41 to grasp the installation position of the temporary parabolic antenna 10. The temporary parabolic antenna 10 is placed on the horizontal / vertical direction adjuster 12 and the direction of the parabolic antenna 10 can be changed. In addition, an infrared scope 13 is attached to the parabolic antenna 10, and the direction seen by the infrared scope 13 is matched with the directivity direction of the parabolic antenna 10. A plurality of peripheral devices (radio device 31, GPS device 11, horizontal / vertical direction adjuster 12, infrared scope 13) of parabolic antenna 10 and control processing device 14 are connected. This control processing device 14 has a function of adjusting the directivity direction of the parabolic antenna 10 by transmitting and receiving signals to and from those peripheral devices.

FIG. 2 shows a block configuration example of the temporary parabolic antenna 10.
In FIG. 2, the temporary parabolic antenna 10 has a configuration in which a radio 31, a GPS device 11, a horizontal / vertical direction adjuster 12, and an infrared scope 13 are connected with a control processing device 14 as a center.

  The GPS device 11 receives radio waves from the GPS satellite 41, acquires latitude / longitude information of the place where the temporary parabolic antenna 10 is installed, and inputs the longitude / latitude information to the control processing device 14. In addition, each latitude and longitude information of the permanent parabolic antenna 20 and the temporary parabolic antenna 10 is exchanged bidirectionally via the wireless devices 31 and 32 and the wireless line 33 so that the pointing direction is directed to the latitude and longitude of the other party. Each antenna direction shall be adjusted. Specifically, it is as follows.

  First, the control processing device 14 adjusts the direction in which the temporary parabolic antenna 10 faces, and the longitude / latitude information of the temporary parabolic antenna 10 from the GPS device 11 and the longitude of the permanent parabolic antenna 20 facing from the radio 31. Latitude information is acquired, and the horizontal / vertical direction adjuster 12 is instructed to face the direction of the permanent parabolic antenna 20 roughly. On the other hand, the opposing parabolic antenna 20 is also adjusted by the horizontal / vertical direction adjuster 22 so as to face the temporary parabolic antenna 10 according to the longitude / latitude information of the temporary parabolic antenna 10, and a completion notification is sent. Notification is made to the temporary parabolic antenna 10. After performing rough direction adjustment in this way, highly accurate direction adjustment is performed by image analysis using the infrared scope 13.

  Image information of the permanent parabolic antenna 20 facing from the infrared scope 13 is acquired, and the arrangement pattern of the heating elements 23 arranged on the contour portion of the permanent parabolic antenna 20 is processed and analyzed from this image. The horizontal / vertical direction adjuster 12 detects a deviation between the center of the arrangement pattern and the center of the image of the infrared scope 13 so that the pointing direction of the temporary parabolic antenna 10 is accurately directed to the direction of the permanent parabolic antenna 20. To adjust the directivity direction of the temporary parabolic antenna 10. When the adjustment of the pointing direction of the temporary parabolic antenna 10 is completed, a notification of the completion of the pointing direction adjustment is received from the horizontal / vertical direction adjusting device 12, and if necessary, the direction is adjusted from the wireless device 31 to the permanent parabolic antenna 20 side. Notify completion.

  By using the infrared scope 13, the permanent parabolic antenna 20 is oriented in the direction in which the temporary parabolic antenna 10 faces, regardless of the situation with the opposing permanent parabolic antenna 20, particularly weather conditions such as night, rain, and fog. It is possible to confirm the arrangement pattern of the heating elements 23 arranged in the outline portion.

FIG. 3 shows an example of the procedure for adjusting the direction of the temporary parabolic antenna 10.
In FIG. 3, first, a temporary parabolic antenna 10 is installed in an emergency location such as a disaster area, and direction adjustment is started (S1). Next, the control processing device 14 acquires latitude / longitude information from the GPS device 11 of the temporary parabolic antenna 10 (S2). In addition, the latitude / longitude information of the permanent parabolic antenna 20 facing the wireless device 31 is acquired (S3). From the latitude and longitude information of the temporary parabolic antenna 10 acquired from the GPS device 11 and the latitude and longitude information of the opposing parabolic antenna 20 obtained from the wireless device 31, the direction of the opposing parabolic antenna 20 is calculated (S4). Based on this calculation direction, the horizontal / vertical direction adjuster 12 is controlled to direct the pointing direction of the temporary parabolic antenna 10 toward the opposing parabolic antenna 20 (S5). There is an opposing parabolic antenna 20 in the pointing direction of the temporary parabolic antenna 10, and an image of the parabolic antenna 20 facing the field of view of the infrared scope 13 is confirmed (S6).

  Next, the arrangement pattern of the heating elements 23 attached to the contour of the permanent parabolic antenna 20 is recognized from the image of the infrared scope 13 (S7). At this time, the control processing device 14 stores the arrangement pattern of the heating element 23 in advance, and collates the stored arrangement pattern with the arrangement pattern obtained from the image of the infrared scope 13, thereby arranging the arrangement pattern of the heating element 23. You may make it recognize as. The arrangement pattern of the heating elements 23 has a predetermined shape corresponding to the attachment position of the contour portion of the parabolic antenna 20. Therefore, it is determined whether or not there is an arrangement pattern of the heating elements 23 at a predetermined position (for example, the center position of the image) of the image of the infrared scope 13 (S8). When the arrangement pattern is at a predetermined position in the image (S8: Yes), the temporary parabolic antenna 10 is directed almost accurately to the opposing parabolic antenna 20. On the other hand, when the arrangement pattern is not at a predetermined position in the image (S8: No), the temporary parabolic antenna 10 is slightly deviated from the facing direction of the permanent parabolic antenna 20. In this case, the directivity direction of the temporary parabolic antenna 10 is finely adjusted (S9). Then, it is determined again whether or not there is an arrangement pattern of the heating elements 23 at a predetermined position of the image of the infrared scope 13, and fine adjustment is repeated until the arrangement pattern reaches a predetermined position of the image (S8, S9). .

  If the pointing direction of the temporary parabolic antenna 10 is directed almost exactly to the opposing parabolic antenna 20 (S8: Yes), further adjustment by the test radio wave transmitted from the opposing parabolic antenna 20 may be performed. Specifically, the test radio wave transmitted from the opposing parabolic antenna 20 is received by the temporary parabolic antenna 10 (S10). It is determined whether or not the reception level of the test radio wave received by the temporary parabolic antenna 20 is above a certain level (S11). In this determination, if the reception level is not above a certain level (S11: No), the directivity direction of the temporary parabolic antenna 10 is slightly shifted, so that fine adjustment of the directivity direction of the temporary parabolic antenna 10 is repeated (S12). ). As a result, if the reception level exceeds a certain level (S11: Yes), the pointing direction of the temporary parabolic antenna 10 is accurately adjusted, and wireless communication with the opposing permanent parabolic antenna 20 is possible. It becomes possible.

FIG. 4 shows an example of a first arrangement pattern of the heating elements 23.
As shown in FIG. 1, three heating elements 23 are arranged on the contour of the permanent parabolic antenna 20. The heating element 23 is an electric heating coil that emits infrared rays, a panel-like or sheet-like heating element. Since infrared light has a longer wavelength than visible light, it can be detected from a distance without being affected by weather such as rain and fog as well as at night.

  FIG. 4A is an image of the infrared scope 13 before fine adjustment of the directivity direction of the temporary parabolic antenna 10. The arrangement patterns of three heating elements 23 (indicated by broken-line circles in the figure) can be seen at positions deviating from the center of the image of the infrared scope 13. The more accurate direction of the opposing parabolic antennas 20 facing each other can be specified by the arrangement pattern of these three heating elements 23. When the image of the infrared scope 13 is an upright image, the direction of the parabolic antenna 20 here is slightly lower left as viewed from the temporary parabolic antenna 10.

  FIG. 4B is an image of the infrared scope 13 after finely adjusting the directivity direction of the temporary parabolic antenna 10. The arrangement pattern (circular shape) of the three heating elements 23 is visible at the center of the image of the infrared scope 13. Since the arrangement pattern (circular shape) of these three heating elements 23 is in the center of the image of the infrared scope 13, the temporary parabolic antenna 10 is accurately oriented in the direction of the opposing permanent parabolic antenna 20. I understand.

FIG. 5 shows a direction adjustment procedure example of the temporary parabolic antenna 10 and an arrangement pattern of the heating elements 23.
In FIG. 5, the arrangement pattern of the heating elements 23 is confirmed from the image of the infrared scope 13 (S21). Next, if necessary, the image is enlarged by the zoom function of the infrared scope 13 (S22), and the displacement of the arrangement pattern is confirmed from the center of the image (S23, arrangement pattern a). Due to the arrangement pattern a of three heating elements 23 (indicated by broken circles in the figure), the direction of the permanent parabolic antenna 20 is slightly upper right when viewed from the temporary parabolic antenna 10, and the horizontal and vertical deviations are confirmed. Is done.

  Next, it is determined whether or not the center of the arrangement pattern of the heating elements 23 is on the vertical center line of the image (S24). When the center of the arrangement pattern is deviated from the vertical center line of the image (S24: No), the horizontal deviation is adjusted by operating the horizontal / vertical direction adjuster 12 of the temporary parabolic antenna 10 (S25). . In the case where the vertical center line is shifted to the right as in the arrangement pattern a, by rotating the temporary parabolic antenna 10 in the right direction (clockwise), the center thereof is set to the vertical center as in the arrangement pattern b. Become on line.

  Next, it is determined whether or not the center of the arrangement pattern of the heating elements 23 is on the horizontal center line of the image (S26). When the center of the arrangement pattern is shifted from the horizontal center line of the image (S26: No), the horizontal / vertical direction adjuster 12 of the temporary parabolic antenna 10 is operated to adjust the vertical shift (S27). . When the horizontal center line is shifted upward as in the arrangement pattern b, the center is positioned on the horizontal center line as in the arrangement pattern c by rotating the temporary parabolic antenna 10 upward. .

  The order of horizontal adjustment and vertical adjustment may be reversed, or may be adjusted at the same time.

  As a result, the center of the arrangement pattern of the heating elements 23 becomes the center of the image of the infrared scope 13, and the pointing direction of the temporary parabolic antenna 10 is accurately directed to the opposing parabolic antenna 20. In this way, by adjusting the directing direction of the temporary parabolic antenna 10 using the infrared scope 13, it can be directed to the permanent parabolic antenna 20 without being affected by the weather such as nighttime, rain, or fog. .

FIG. 6 shows an example of a second arrangement pattern of the heating elements 23.
The heating elements 23 of the second arrangement pattern are arranged on the contour portion of the permanent parabolic antenna 20 and the wall surface of the base station building 21.

  FIG. 6 (1) is an image of the infrared scope 13 before fine adjustment of the directivity direction of the temporary parabolic antenna 10. In the image of the infrared scope 13, an arrangement pattern of three heating elements 23 (indicated by broken-line circles in the figure) arranged on the contour of the permanent parabolic antenna 20 and the wall of the base station building 21 are arranged. The arrangement pattern of the four heat generating elements 23 is displayed, and the direction of the opposing parabolic antenna 20 facing can be specified by specifying the circular arrangement pattern. When the image of the infrared scope 13 is an upright image, the direction of the permanent parabolic antenna 20 is slightly leftward as viewed from the temporary parabolic antenna 10.

  FIG. 6B is an image of the infrared scope 13 after finely adjusting the directivity direction of the temporary parabolic antenna 10. A circular arrangement pattern is visible at the center of the image of the infrared scope 13. Since the arrangement pattern (circular shape) of these three heating elements 23 is in the center of the image of the infrared scope 13, the temporary parabolic antenna 10 is correctly oriented in the direction of the opposing permanent parabolic antenna 20. I understand.

  In this way, not only the heating element 23 is arranged on the contour of the opposing permanent parabolic antenna 20 but also the wall surface of the base station building 21, so that the permanent parabolic antenna 20 can be seen from the image of the infrared scope 13. The direction can be easily specified. That is, by arranging a large number of heating elements 23 over a wide range, such as the outline of the parabolic antenna 20 and the wall surface of the base station building 21, it becomes easy to detect from a distance.

  In this method, it is necessary to be able to distinguish between the arrangement pattern A of the heating elements 23 in the contour portion of the permanent parabolic antenna 20 and the arrangement pattern B of the heating elements 23 arranged at other locations. Here, since both parabolic antennas are almost directly opposed by prior antenna adjustment (S1 to S5 in FIG. 3) based on the longitude and latitude information of the permanent parabolic antenna 20 and the temporary parabolic antenna 10, the arrangement is visible from the infrared scope 13. Of the pattern A and the arrangement pattern B, the arrangement pattern A can be recognized as a predetermined shape (here, circular) regardless of the positional relationship between the parabolic antennas.

  On the other hand, since the heating element 23 arranged on the wall surface of the base station building 21 is fixed, the shape (appearance) of the arrangement pattern B differs depending on the positional relationship between the permanent parabolic antenna 20 and the temporary parabolic antenna 10. That is, in order to distinguish between the arrangement pattern A having a fixed shape and the arrangement pattern B having a variable shape as an image of the infrared scope 13, it is effective to separate the arrangement locations of the respective heating elements 23, for example, in the vertical direction. In this case, for example, the arrangement pattern A is recognized from the image of the infrared scope 13 only for a predetermined number (here, three) of the heating elements 23 from the top. Thereby, the orientation of the temporary parabolic antenna 10 can be controlled so that the center of the arrangement pattern A becomes the center of the image of the infrared scope 13.

FIG. 7 shows an example of a third arrangement pattern of the heating elements 23.
In the second arrangement pattern shown in FIG. 6, it takes time to arrange the heating element 23 on the wall surface of the base station building 21. Therefore, the permanent parabolic antenna 20 is placed on the roof of the base station building 21 with the antenna post / pedestal 24 mounted thereon, and the heating element 23 of the third arrangement pattern is the contour of the permanent parabolic antenna 20 and the antenna post / pedestal. 24. It is easier for the heating element 23 to be arranged on the antenna support / pedestal 24 on the roof of the base station building 21 than on the wall surface of the base station building 21.

  Even in this case, for example, the arrangement pattern A (circular shape) is identified only for a predetermined number (three in this case) of heating elements 23 from the top of the image of the infrared scope 13, and the center of the arrangement pattern A is the center of the infrared scope 13. The orientation of the temporary parabolic antenna 10 can be controlled so as to be in the center of the image.

  In the above embodiment, the case where the directivity direction of the temporary parabolic antenna 10 is adjusted with respect to the permanent parabolic antenna 20 installed in the base station building 21 has been described. However, the present invention is directed between the temporary parabolic antennas 10. The present invention can also be applied when adjusting the direction.

  That is, both the temporary parabolic antennas 10 are provided with the GPS device 11 and the infrared scope 13, and a plurality of heating elements are arranged in the outline of the parabolic antenna 10 or in the vicinity thereof. Then, the position information detected by receiving the radio waves from the GPS satellites is notified to each other via, for example, the radio devices 31 and 32 and the radio line 33 used for disaster prevention wireless communication shown in FIG. 1, and the position information is used. Coarse adjustment is performed so that the directivity directions of both temporary parabolic antennas 10 face each other. Further, infrared rays emitted from a plurality of heating elements of the opposing parabolic antenna 10 are detected, and a deviation between the center of the image of the infrared scope and the center of the arrangement pattern of the heating elements displayed in the image is detected, The directivity directions of both temporary parabolic antennas 10 are finely adjusted in the direction in which the deviation is reduced.
