And a telemeter display device 112 for visualizing and displaying telemeter data for imaging by the monitoring camera 121. The video transmission device 12 is a monitoring camera 121 that can capture an image of a monitoring target area by turning in a pan direction and a tilt direction, and transmits video data captured by the monitoring camera 121 via a transmission path 14. It has a part 122. Next, a description will be given of the center-side device 13 which is installed at a location distant from the observation target or the monitoring target, such as a road or a dam facility, and monitors by collecting data from the monitoring-side device. The center-side device 13 includes a receiving unit 131 that receives video data from the transmitting unit 122 of the video transmitting device 12 via the transmission path 14, and a monitor 132 that displays the video data received by the receiving unit 131.

The operation of the remote monitoring system according to one embodiment of the present invention will be described below. FIG. 6 which is a flowchart showing the monitoring procedure is used for the description. Generally, observation of telemeter data such as rainfall and wind speed is not always performed, but is performed at predetermined intervals (for example, every 30 minutes).
Done in This is because there is no rapid change in rainfall or wind speed in a condition where the weather is stable, and the operation is performed by switching the observation interval according to the weather condition.
On the other hand, in the monitoring by the monitoring camera, the monitoring target area is monitored by turning the monitoring camera in the pan direction and the tilt direction. The turning of the surveillance camera can be performed by a preset function that registers the settings of the surveillance camera to image a specific monitoring target object,
It can be performed at any time by operation from the center-side device. First, it is detected by the clock means (not shown) of the video transmission device 12 whether or not the time to observe the telemeter data has arrived (step 61). If it is time to observe the telemeter data, the telemeter display device 112
The surveillance camera 121 is turned and zoomed using the preset function in order to capture an image of (Step 62). FIG. 2 shows an image of the telemeter display device 112 captured by the surveillance camera 121. The telemeter display device 11 has a predetermined size at the center of the angle of view 21 of the surveillance camera 121.
It can be seen that turning and zooming have been performed at the position where 2 appears. The predetermined size is at least a size that can be visually recognized by the monitor 132, and is preferably the image processing unit 134.
The size is appropriate for image processing. When performing image processing, the display unit 1121 of the telemeter display device 112
(In FIG. 2, “30”) is required to have a sufficient size and luminance. Therefore, the display unit 1121
It is preferable to use a high luminance light emitting element such as an LED. FIG. 3 shows preset contents of the monitoring camera 121. For each of a plurality of monitoring targets, an absolute angle (an angle from a predetermined reference position) and a zoom for designating a monitoring position are stored. That is, the preset number 1 has an absolute angle (the pan direction 30) for imaging the “rainfall display plate at the point A” as the telemeter display device 112 with the high magnification zoom.
Degree, tilt direction 10 degrees) and zoom (2 times) are stored. The preset number 2 stores an absolute angle (pan direction 0 degrees, tilt direction 0 degrees) and zoom (1) in order to capture the point B in a wide angle. The preset number 3 stores an absolute angle (45 degrees in the pan direction and 15 degrees in the tilt direction) and a zoom (1 time) in order to capture a wide angle image of the point C. That is, in step 62, the surveillance camera 121 is moved in the pan direction 30 by the absolute angle based on the setting contents of the preset number 1.
Turn to the position of 10 degrees in the tilt direction, and monitor camera 1
Camera control to double the zoom of the 21 lens is performed.

Then, the monitoring camera 121 is set to the preset number 1, the telemeter display device 112 is imaged at a predetermined angle of view shown in FIG. 2, and the telemeter data is transmitted as video data from the transmission unit 122 via the transmission line 14. To the center-side device 13 (step 63). In the center-side device 13, video data (hereinafter, referred to as telemeter video) related to telemeter data received from the transmitting unit 122 via the transmission path 14 by the receiving unit 131 is recorded by the recording unit 1.
33 is recorded (step 64). FIG. 4 shows the recording unit 133.
This is an example of a recording method according to the present invention. If a telemeter video is recorded with a time stamp having date and time information added thereto, the work of summing up telemeter data can be efficiently performed later. On the other hand, if it is determined in step 61 that it is not the time to observe the telemeter data, the surveillance camera 121 is turned and zoomed using the preset function to image a surveillance location such as point B or point C, Transmitting unit 1 by imaging a desired monitoring location
Then, the video data of each monitoring location is transmitted from 22 to the center device 13 via the transmission path 14 (step 65). In the center-side device 13, the monitor 132 displays the video data (hereinafter, referred to as monitoring video) relating to the monitoring target received from the transmitting unit 122 via the transmission path 14 by the receiving unit 131 (step 66). Monitoring is performed based on the monitoring video projected on 132.

Hereinafter, the counting process of the telemeter data in the center device 13 will be described with reference to FIG.
First, the telemeter video to which the time stamp is added is read from the recording unit 133 (Step 71). Recording unit 13
In the third case, the surveillance video may be recorded. In this case, if the telemeter video and the surveillance video are classified and recorded in another area, the telemetry data aggregation process can be performed efficiently. it can. Image processing is performed on the telemeter video read out in step 71 to extract telemeter data such as rainfall (step 72). If the case of FIG. 2 is described as an example, the telemeter display device 112 is fixed,
Since the telemeter image is acquired using the preset function of the monitoring camera 121, the display unit 1121 is imaged at a fixed position of the angle of view 21.
Character recognition using image processing is performed at the position where 21 is imaged, and a rainfall of “30” mm can be extracted.
Since image processing is not performed on all the video data of the angle of view 21, the processing load is light and the processing time is short. The data tabulation unit 135 tabulates the telemeter data extracted in step 72 as shown in FIG. 5 in association with the observation date and time indicated by the time stamp (step 73). By looking at the list that has been subjected to the tallying process, it is possible to grasp the status of changes such as rainfall.

According to the above-described embodiment of the remote monitoring system of the present invention, the telemeter / data display device 112 is transmitted to the center device 13 as video data obtained by capturing an image with the monitoring camera 121. There is no need to provide a dedicated transmission path for transmitting telemeter data. The monitoring side and the center side
It suffices to have one transmitting means and one receiving means. Therefore, telemeter systems and industrial surveillance cameras
Construction costs and equipment costs can be reduced as compared with the case where the systems are separately and independently constructed. In addition, since a time stamp is added to the telemeter video and recorded in the recording unit 133, a totaling process of the telemeter data can be easily performed. In addition, since the original telemeter data is automatically extracted by subjecting the telemeter video to image processing by the image processing unit 134, the total processing of the telemeter data can be easily performed. Also, the monitoring camera 121
, The desired telemeter image can be easily obtained. The present invention is not limited to the above embodiment, and can be variously modified without departing from the gist of the present invention.

For example, the telemetry image may not be recorded in the recording section 133, but may be input directly to the image processing section 134 to perform the totaling processing in real time. Also,
By displaying the telemeter image on the monitor 132, the monitor of the center device 13 may perform the tallying process. Alternatively, video data may be obtained by manual operation from the center-side device 13 without using the preset function of the monitoring camera 121. Further, the telemeter data observed by the telemeter measuring device 111 is visualized and displayed on the telemeter display device 112. However, in a simpler system, the telemeter measuring device 111 such as a rain gauge or an anemometer is monitored by the monitoring camera 121. You may make it image directly. For example, if the windsink installed on a highway or the like is imaged by the monitoring camera 121, it is possible to obtain general telemeter data on the current wind direction and wind speed. FIG. 8 shows video data obtained by capturing the windsock 82 with the monitoring camera 121. Using the image processing unit 134, a simple telemeter data aggregation process can be performed. That is,
Streaming using the preset function of the monitoring camera 121 8
2, the pole 8 on which the windsock 82 is attached
1 is fixed, so that the pole 81 is imaged at a fixed position of the angle of view 21, image processing is performed on the vicinity of the pole 81, and a stream 82 is extracted. In the case of a), it is determined that there is no crosswind. In FIG. 8B, it is determined that there is a weak crosswind from the left. In the case of FIG. 8C, it is determined that there is a strong crosswind of the left.
