Description

  The present invention relates to a wind direction / wind speed monitoring apparatus, a wind direction / wind speed monitoring method, a wind direction / wind speed monitoring program, a recording medium recording the program, a wind direction / wind speed monitoring system, and a wind direction. / Concerning an anemometer monitoring device.

  Conventionally, the wind direction / wind speed monitoring system receives the measurement data (wind direction value, wind speed value) from the wind direction / anemometer at the remote measuring point at the monitoring center and stops operation by receiving the wind speed value above the alarm value. As a traffic regulation trigger. For example, in a railway network, a main station is a monitoring center, and an anemometer / anemometer and a transmitter for transmitting measurement data thereof are installed at predetermined intervals on a railway line. Further, a metallic cable is used for the transmission path from the transmission device to the monitoring center and is laid in a pit beside the track.

  In such a wind direction / wind speed monitoring system, a wind direction / anemometer modeled on the shape of a propeller airplane is generally used. That is, the wind direction can be detected by detecting the wind speed with a rotatable propeller unit and rotatably mounting the wind direction / anemometer with the pole as the wind direction axis.

  Such a movable anemometer / anemometer may cause measurement data anomalies and malfunction of the anemometer / anemometer due to icing of water droplets adhering to the movable part and intrusion of dust or water droplets inside. Therefore, in a conventional wind direction / wind speed monitoring system using a movable wind direction / anemometer, a system that promptly detects abnormality of the wind direction / anemometer using measured data from the wind direction / anemometer has been proposed. (For example, refer to Patent Document 1 below.)

  This wind direction / wind speed monitoring system is configured to output an anomaly warning of the wind direction / anemometer when it is detected that the no-wind state has continued for a predetermined time and when the wind direction has been changed a predetermined number of times within a predetermined time. It has become.

  In addition, in order to increase the reliability of the anemometer / anemometer, a special anemometer / anemometer having no moving parts like the conventional anemometer / anemometer has been proposed. Furthermore, a system has also been proposed that provides a landscape image taken by an omnidirectional camera arranged in the vicinity of this special wind direction / anemometer together with measurement data from the wind direction / anemometer (for example, the following patent document) 2). In this wind direction / wind speed monitoring system, a landscape image around the installation position of the wind direction / anemometer can be provided to the user from the monitoring center.

  However, in the conventional wind direction / anemometer described above, if an abnormality occurs due to the noise from the wind direction / anemometer to the transmission path, an incorrect wind direction value and wind speed value are provided, and the reliability of the measurement data is improved. There was a problem of being low.

  In addition, it is useful to use the existing transmission line because the transmission line is several tens of kilometers, but the existing transmission line uses a metallic cable. Noise is likely to occur. For example, when the transmission path is laid on a railway network, noise may be added if measurement data is transmitted while a railway vehicle such as a bullet train or a train is traveling on the track. For this reason, when a transmission line (for example, an optical cable) that is less influenced by noise is newly laid instead of the already laid metallic cable, there is a problem that the equipment cost increases.

  Also, in locations where optical cables that are less affected by noise are already laid, the frequency of occurrence of abnormalities in measured data is lower than that of metallic cables, but once noise occurs in measured data, it is the same as for metallic cables. Therefore, there is a problem in that the reliability of the measurement data is deteriorated because an incorrect wind direction value and wind speed value are provided.

  In the wind direction / wind speed monitoring system of Patent Document 1 described above, a landscape image in the vicinity of the wind direction / anemometer is captured, and the wind direction / anemometer itself is not photographed. Can not be monitored. Also, even if the anemometer / anemometer is imaged, the anemometer / anemometer has no moving parts, so just looking at the video from the surveillance camera does not tell whether the anemometer / anemometer is functioning properly, There is a problem that monitoring by the supervisor is wasted.

  A monitoring camera may be installed and monitored to confirm the actual behavior of the movable anemometer / anemometer. In this case, it is necessary for the supervisor to constantly view the video from the monitoring camera in the monitoring center. There is a problem that the burden on the observer increases.

  Further, simply viewing the video from the surveillance camera cannot distinguish whether the wind direction / anemometer is normal or malfunctioning, and there is a problem that monitoring by the supervisor is wasted. For example, in the case of an image in which the propeller unit is not rotating, it cannot be determined from the image from the monitoring camera whether there is no wind or rotation is not possible due to a failure.

  Thus, although the transmission path is an essential element in the wind direction / wind speed monitoring system, the reliability of the measurement data is reduced by using the transmission path. Therefore, there is a problem in that safe operation is hindered if it is determined that there is no wind based on the measurement data in spite of the strong wind.

  In addition, when the equipment cost increases with respect to the transmission path, the penetration rate into the traffic network decreases, and there arises a problem that safety cannot be covered. Furthermore, even if the wind direction / anemometer is monitored with a monitoring camera, the burden on the observer increases, and the monitoring itself is wasted.

(Schematic configuration of the wind direction / wind speed monitoring system)
First, a schematic configuration of a wind direction / wind speed monitoring system according to an embodiment of the present invention will be described. FIG. 1 is an explanatory diagram showing a schematic configuration of a wind direction / wind speed monitoring system according to an embodiment of the present invention. Here, a railway network will be described as an example of a transportation network.

  In FIG. 1, a wind direction / wind speed monitoring system 100 includes a plurality of measuring devices 101 installed at each observation point and a wind direction / wind speed monitoring device 102 functioning as a server. 2 transmission lines 112).

  In a traffic network, for example, a railway network, the measuring device 101 is provided with an anemometer / anemometer 121 and a first transmitter 122 that transmits measurement data at observation intervals on a track 150 at predetermined intervals. The wind direction / anemometer 121 outputs a signal relating to the wind direction / wind speed at the observation point serving as the installation position. Hereinafter, when “wind direction / wind speed” is described, at least the wind speed is included among the wind direction and the wind speed. The wind direction / anemometer 121 may be movable as described in the background art section, or may be non-movable. In the following description, the movable wind direction / anemometer 121 will be described.

  Further, the first transmitter 122 performs signal processing of the measurement signal related to the wind direction / wind speed obtained from the wind direction / anemometer 121, and the wind direction / wind speed monitoring device 102 via the first transmission path 111 as measurement data. Send to. The wind direction / anemometer 121 and the first transmitter 122 are connected by a third transmission path 123. A wind direction / wind speed signal output from the wind direction / anemometer 121 is sent to the first transmitter 122 via the third transmission path 123.

  The wind direction / anemometer monitoring device 130 images the behavior of the wind direction / anemometer 121 and transmits the captured image to the wind direction / anemometer monitoring device 130 via the second transmission path 112. Details of the wind direction / wind speed monitoring apparatus 102 will be described later with reference to FIG.

  The transmission line 110 (the first transmission line 111 and the second transmission line 112) is a cable that connects the measuring device 101 and the wind direction / wind speed monitoring device 102, and specifically, along the line 150. It is laid in 150 pits. The transmission line 110 is a metallic cable or an optical cable. When a railway vehicle such as a Shinkansen travels during transmission on the transmission path 110, noise may be superimposed on the measurement data or captured image being transmitted.

  In the present invention, since the focus is on the influence of noise generated during transmission in the transmission line 110, it is preferable to use an optical cable that is less affected by noise than the metallic cable. However, in the railway network, the metallic cable is already laid. Therefore, it is preferable to use the metallic cable as it is as the first transmission path 111 from the viewpoint of installation cost.

  The same applies to the third transmission path 123 connecting the wind direction / anemometer 121 and the first transmitter 122. On the other hand, since the second transmission path 112 is a transmission path 110 newly laid, it may be a metallic cable or an optical cable. Hereinafter, the first transmission path 111 and the third transmission path 123 will be described as a metallic cable, and the second transmission path 112 will be described as an optical cable.

  Further, the wind direction / wind speed monitoring apparatus 102 receives measurement data regarding the wind direction / wind speed obtained from the wind direction / anemometer 121 and the first transmitter 122 via the first transmission path 111. Then, the wind speed value and the wind direction (direction) indicated by the measurement data are notified. Moreover, when it is a strong wind state (for example, wind speed 20km or more), a strong wind warning is alert | reported. In addition, the wind direction / wind speed monitoring device 102 stores a series of captured images obtained from the wind direction / anemometer monitoring device 130, and extracts and analyzes the stored captured images as necessary, thereby obtaining measurement data. Detect anomalies. If an error is found, an abnormality alarm is notified.

(Specific Configuration of Measuring Device 101)
Next, a specific configuration of the measurement apparatus 101 shown in FIG. 1 will be described. FIG. 2 is an explanatory diagram showing a specific configuration of the measuring apparatus 101 shown in FIG. In FIG. 2, first, the wind direction / anemometer 121 includes a measurement main body 121a and a wind direction axis 121b. The measurement main body 121a is rotatably attached to the wind direction axis 121b and indicates the direction in which the wind blows. The measurement main body 121a is modeled on the shape of a propeller airplane, and the direction indicated by the nose is the wind direction. The direction indicated by the nose at this time is a wind direction measurement signal. Further, a propeller is rotatably supported at the tip of the nose and rotates when wind blows. This rotational speed becomes a measurement signal of the wind speed. Each measurement signal is received by the first transmitter 122 through the third transmission path 123.

  The first transmitter 122 includes an A / D converter 122a and a transmission unit 122b. The A / D converter 122a converts the analog signal measurement signal transmitted from the wind direction / anemometer 121 into digital signal measurement data. The transmission unit 122 b transmits the measurement data to the wind direction / wind speed monitoring device 102 through the first transmission path 111. This measurement data represents the measured value of wind direction / velocity.

  The wind direction / anemometer monitoring device 130 monitors the behavior of the wind direction / anemometer 121. Specifically, the behavior of the wind direction / anemometer 121 is indirectly monitored by monitoring a windsock 131 installed at the same position as or near the wind direction / anemometer 121. The wind direction / anemometer monitoring device 130 includes a windsock 131 supported by a pole 132, a camera 133 that captures the windsock 131, and a second image that transmits a captured image captured by the camera 133 to the wind direction / wind speed monitoring device 102. And a transmitter 134.

  The windsock 131 is a tool for visually informing the direction and strength of the wind, which is obtained by connecting a cylindrical cloth to the pole 132 with a rope. The windsock 131 is installed at the same position as or near the wind direction / anemometer 121. Here, the near position is specifically a position at which the same wind direction / wind speed as the wind direction / anemometer 121 can be measured. For example, a radius of 5 [m] or 10 [m] from the wind direction / anemometer 121 may be used. Further, when the position is the same as that of the wind direction / anemometer 121, it is attached to the wind direction axis 121b of the wind direction / anemometer 121.

  In addition, the camera 133 images the windsock 131. Here, two cameras 133 (the first camera 133a and the second camera 133b) directed to the windsock 131 are installed at positions that are horizontal to the ground and perpendicular to each other, and imaging of the windsock 131 from the installation position. By obtaining an image, the approximate wind direction and wind speed (wind intensity) of the windsock 131 can be obtained by the wind direction / wind speed monitoring device 102.

  The second transmitter 134 includes an encoder 134a and an E / O converter 134b. The encoder 134a encodes the captured image from the camera 133. The E / O converter 134b converts the encoded captured image (electrical signal) into an optical signal, and transmits the optical signal to the wind direction / wind speed monitoring apparatus 102 through the second transmission path 112 (optical cable).

  Next, wind direction / wind speed imaging by the camera 133 will be described. FIG. 3 is an explanatory diagram showing imaging of the wind direction by the camera 133. In FIG. 3, it is assumed that the first camera 133a is directed from south to north, and the second camera 133b is directed from west to east. As for the direction, the north is represented as 0 ° (360 ° when rounded), the east as 90 ° (450 ° when rounded), the south as 180 °, and the west as 270 °.

  When the windsock 131 is imaged on the right side of the pole 132 by the first camera 133a, the wind is blowing at least in the north-south direction, and the wind direction is estimated to be between 0 ° and 180 °. On the other hand, when the windsock 131 is imaged to the left of the pole 132, the wind is blowing at least in the south to north direction, and the wind direction is estimated to be between 180 ° and 360 °.

  When the windsock 131 is imaged on the right side of the pole 132 by the second camera 133b, it is estimated that the wind is blowing at least in the east to west direction, and the wind direction is between 90 ° and 270 °. The On the other hand, when the windsock 131 is imaged to the left of the pole 132, the wind is blowing at least in the west to east direction, and the wind direction is estimated to be between 270 ° and 450 °.

  Therefore, the direction in which the windsock 131 flows by the two cameras 133 is specified between north and east, between east and south, between south and west, and between west and north. Further, when it is desired to obtain a more detailed direction, it can be specified by performing image analysis based on the position of the striped pattern image of the windsock 131 and the position of the image on the free end side of the windsock 131. Such an analysis process is executed by an analysis unit described later.

  FIG. 4 is an explanatory diagram showing imaging of the wind speed by the camera 133. The wind speed can be specified by either one of the cameras 133. Here, description will be made using the first camera 133a. Since the first camera 133a captures an image of the rising and rising posture, the pole 132 and the angle (the lifting angle) θ of the blowing are analyzed. If the lift angle θ is equal to or greater than a threshold value (for example, 80 °) indicating a strong wind state, it can be determined that the wind is strong. In addition, when the lift angle θ is equal to or less than a threshold value (for example, 0 ° or 5 °) indicating a windless state, it can be determined that there is no wind. This analysis process is also executed by an analysis unit described later.

  When a strong wind with a wind speed of 10 m or more is blowing, the windsock 131 swings up and down at that moment, so that the rising angle of the windsock 131 increases or falls below a threshold value indicating a strong wind state. There is. In such a case, if the captured image that happens to be analyzed falls below the threshold value, the wind speed is erroneously detected. Therefore, a series of captured images obtained for a certain period of time are analyzed and averaged. Thus, the reliability of the analysis result can be improved.

(Wind direction / wind speed monitoring procedure)
Next, the wind direction / wind speed monitoring processing procedure of the wind direction / wind speed monitoring apparatus 102 according to the embodiment of the present invention will be described. 7 and 8 are flowcharts showing the wind direction / wind speed monitoring processing procedure of the wind direction / wind speed monitoring apparatus 102 according to the embodiment of the present invention. In this flowchart, it is assumed that measurement data and a captured image are sequentially captured.

  In FIG. 7, first, it is determined whether or not T1 ≦ V (step S701). Here, T1 is a threshold value indicating strong wind, and V is a measured value related to the wind speed received at a certain timing. If T1 ≦ V (step S701: Yes), it is determined that the measurement data (measurement value) is in a strong wind state, so an image extraction start trigger is output (step S702), and imaging for a predetermined time is performed. An image is extracted from the image DB 610 (step S703).

  Here, the picked-up images for a predetermined time are a series of picked-up images based on the output time of the image cutting start trigger. For example, it may be a series of captured images going back a predetermined time from the output of the image cutout start trigger, or a series of captured images for a predetermined time from the output of the image cutout start trigger. Thereby, the picked-up image of the windsock 131 at the time of measuring measurement data can be obtained.

  Next, the extracted captured image is analyzed by the analysis unit 604, and the lift angle of the windsock 131 and the direction in which the windsock 131 is flowing are obtained (step S704). Then, the determination unit 605 determines whether or not the measurement value is appropriate (step S705).

  When it is determined that it is not valid (step S705: No), the abnormality alarm information is output (step S706). On the other hand, when it determines with it being appropriate (step S705: Yes), a strong wind warning information is output (step S707).

  If it is less than T1 in step S701 (step S701: No), the process proceeds to step S801 in FIG. Then, it is determined whether or not T2 ≧ V (step S801). Here, T2 is a threshold value indicating a windless state. If T2 ≧ V is not satisfied (step S801: No), neither strong wind nor no wind is returned, and the process returns to step S701 in FIG.

  On the other hand, if T2 ≧ V (step S801: Yes), the monitoring timer starts counting (step S802) and an image extraction start trigger is output (step S803). Then, after the monitoring timer starts, it is determined whether T2 ≧ V (step S804).

  When T2 ≧ V (step S804: Yes), during the monitoring timer operation, the state where the measured value V regarding the wind speed sequentially taken is equal to or less than the threshold value T2 indicating the no-wind state is continued. At this time, a series of captured images captured during operation of the monitoring timer is extracted from the image DB 610. Then, the analysis unit 604 analyzes the extracted series of captured images, and obtains the rising angle of the windsock 131 and the direction in which the windsock 131 flows for each captured image (step S805).

  Then, the determination unit 605 determines whether or not the measurement value is appropriate (step S806). When it is determined that the measured value is not valid (step S806: No), the abnormality alarm information is output (step S807). As a result, the series of processes is completed. On the other hand, when it is determined that the measured value is valid (step S806: Yes), it is determined whether or not monitoring is being performed, that is, whether or not the monitoring timer is operating (step S808). (Step S808: Yes), the process proceeds to step S805, and the newly captured image is analyzed (step S805).

  On the other hand, when T2 ≧ V is not satisfied (step S804: No), or when monitoring is not being performed (step S808: No), an image extraction stop trigger is output (step S809). Thereby, extraction of the captured image by the extraction unit 603 is stopped. Thereafter, the process proceeds to step S701 in FIG.

  As described above, according to the above-described embodiment, when an abnormality occurs due to the influence of noise from the wind direction / anemometer 121 to the transmission path 110 and erroneous wind direction / wind speed measurement data (measured value) is received. Even so, it is possible to detect the correctness of the measurement data by analyzing the captured image of the windsock 131. Therefore, when the measurement data determines that the wind is strong, and the determination unit 605 determines that the measurement data is valid, there was no abnormality during the transmission of the wind direction / anemometer 121 or the transmission path 110. Thus, a highly reliable strong wind warning can be notified.

  Further, when it is determined that the strong wind state is based on the measurement data, if it is determined that the measurement data is not valid, there is an abnormality in the transmission of the wind direction / anemometer 121 or the transmission path 110. Abnormal alarm information can be output.

  Similarly, when it is determined that there is no wind from the measurement data, if the determination unit 605 determines that the measurement data is valid, the wind direction / anemometer 121 and the transmission path are determined. There is no problem during the transmission of 110, and there is no problem. On the other hand, when the determination unit 605 determines that the measurement data is not valid, it is found that there is no abnormality during the transmission of the wind direction / anemometer 121 and the transmission path 110 in fact, not in a no wind state. Therefore, abnormality alarm information can be output.

  In addition, since a metallic cable is used in the existing transmission line 110, noise is easily superimposed on measurement data and captured images, but even if noise is superimposed on measurement data and an erroneous measurement value is obtained, The validity can be determined by analyzing the captured image. On the other hand, the lift angle of the windsock 131 obtained by the analysis process and the direction in which the windsock 131 are flowing are rough values, and therefore, even if noise is superimposed on the captured image, there is almost no influence.

  Therefore, it is possible to accurately detect an abnormality in measurement data even with an existing metallic cable. Moreover, regarding the first transmission line 111 as described above, the existing metallic cable can be used as it is, so that the equipment cost can be reduced.

  In addition, since it is possible to automatically detect an abnormality in the measurement data by analyzing the captured image, instead of judging an abnormality in the measurement data by the supervisor looking at the captured image of the windsock 131, the burden on the administrator Mitigation can be achieved.

  From the above, in the above-described embodiment, the transmission line 110 affected by noise is an essential element, but the reliability of the measurement data can be improved even if the transmission line 110 is used. In addition, this makes it possible to warn that there is a strong wind accurately when there is a strong wind, and thus it is possible to perform safe operation in the traffic network. In addition, regarding the transmission line 110, it is only necessary to add the second transmission line 112 to the existing first transmission line 111, so that the equipment cost is not excessively increased and the cost can be reduced.

  Further, the above-described wind direction / anemometer monitoring device 130 images the behavior of the windsock 131, but the configuration in which the measurement body 121a of the wind direction / anemometer 121 is imaged from the front by attaching the camera 133 to the wind direction axis 121b. It is good. In this case, the captured image of the propeller pattern is analyzed by adopting a configuration in which the propeller pattern changes depending on the rotation speed of the propeller. By comparing the wind speed value obtained from the analysis result with the measured value related to the wind speed, the validity of the measured value related to the wind speed can be determined.

  As described above, according to the wind direction / wind speed monitoring device 102, the wind direction / wind speed monitoring method, the wind direction / wind speed monitoring program, the recording medium on which the program is recorded, and the wind direction / anemometer monitoring device 130, the measurement of the wind direction / wind speed is performed. By automatically detecting the abnormality of the value, it is possible to improve the reliability of the abnormality detection, and thereby to improve the safety of operation in transportation.

  The wind direction / wind speed monitoring method described in the present embodiment can be realized by executing a program prepared in advance on a computer such as a personal computer or a workstation. This program is recorded on a computer-readable recording medium such as a hard disk, a flexible disk, a CD-ROM, an MO, and a DVD, and is executed by being read from the recording medium by the computer. The program may be a transmission medium that can be distributed via a network such as the Internet.
