  Also in the following embodiments, transmission of similar video data and other types of video data can be transmitted / received via the public line 100, and thus description thereof will be omitted as appropriate.

  Next, the operation of the monitoring system according to the first embodiment configured as described above will be described based on the flowchart of FIG. The monitoring center 3 acquires the images of the monitoring locations 11, 12, 13, and 14 of the rivers 1 and 2 as the image data 611, 612, 613, and 614 from the first imaging units 811, 812, 813, and 814, respectively ( Step ST1 in FIGS. 4 and 6). The mobile terminals 15 and 16 transmit their GPS position information 815 and 816 to the monitoring center 3 (step ST10 in FIG. 6).

  Next, as illustrated in FIG. 5, the acquisition unit 6 acquires GPS position information 815 and 816 of the mobile terminals 15 and 16. The determination unit 7 determines whether or not the pieces of position information 815 and 816 acquired by the acquisition unit 6 exist in the distribution areas 511, 512, 513, and 514 of the monitoring table illustrated in FIG. Determination is made (step ST2 in FIG. 6). According to FIG. 1, it is determined that the mobile terminal 15 exists in the distribution area 511. Further, it is determined that the mobile terminal 16 exists in the distribution area 514.

  Next, the determination unit 7 transmits the video data 611 of the monitoring location 11 of the first river 1 to the mobile terminal 15 that has been determined to exist within the distribution area 511. Then, the portable terminal 15 displays the video data 611. In addition, the determination unit 7 transmits the video data 614 of the monitoring location 14 of the second river 2 to the mobile terminal 16 that has been determined to exist within the distribution area 514. And the portable terminal 16 displays the said video data 614 (step ST11 of FIG. 6).

  Next, the 1st extraction part 5 shows the water level of each monitoring location 11, 12, 13, 14 from each video data 611,612,613,614 as the 1st extraction value 711,712,713,714 in FIG. (Step ST3 in FIG. 6). Next, the determination unit 7 transmits the first extraction value 711 as the water level of the monitoring location 11 of the first river 1 to the mobile terminal 15 existing in the previously determined distribution area 511. Then, the mobile terminal 15 displays the first extracted value 711. In addition, the determination unit 7 transmits the first extraction value 714 of the monitoring location 14 of the second river 2 to the mobile terminal 16 existing in the distribution area 514. And the portable terminal 16 displays the said 1st extraction value 714 (step ST12 of FIG. 6).

  Next, the determination unit 7 sets the first threshold values 111, 112, 113, and 114 as water levels for determining evacuation in advance for each of the monitoring locations 11, 12, 13, and 14 in the monitoring table shown in FIG. (Step ST4 in FIG. 6). Next, the determination unit 7 exceeds the first extraction values 711, 712, 713, and 714 extracted by the first extraction unit 5 and the first threshold values 111, 112, 113, and 114 corresponding to the first extraction values 711, 712, 713, and 714, respectively. The evacuation judgment of no is performed (step ST5 of FIG. 6).

  Next, the location information 815, 816 is included in the distribution areas 511, 512, 513, 514 of the corresponding monitoring locations 11, 12, 13, 14 determined to exceed the first threshold values 111, 112, 113, 114. The evacuation signal is transmitted to the portable terminals 15 and 16, and the portable terminals 15 and 16 receive (step ST13 in FIG. 6). For example, if the determination unit 7 determines that the first extracted value 711 of the monitoring location 11 of the first river 1 exceeds the first threshold value 111, the portable terminal having the position information 815 in the distribution area 511 of the monitoring location 11 15 sends an evacuation signal. The evacuation signal is composed of at least one of a voice signal, a vibration signal, a message signal, and an optical signal.

  In the above embodiment, the video data 611 and 614 and the first extracted values 711 and 714 corresponding to the mobile terminals 15 and 16 are transmitted before it is determined that evacuation is necessary. The video data 611 and 614 and the first extracted values 711 and 714 may be transmitted to the mobile terminals 15 and 16 after it is determined that an evacuation signal is necessary.

An evacuation signal can be transmitted to a portable terminal at a required location.

  Further, the determination unit transmits the video of the monitoring location and the first extracted value to the mobile terminal having the GPS location information in the distribution area corresponding to the monitoring location. You can easily obtain and check the information.

  The evacuation signal is at least one of an audio signal, a vibration signal, a message signal, and an optical signal. The mobile terminal can easily acquire and confirm the evacuation signal.

  As a matter of course, being able to confirm with a portable terminal means that a user who has the portable terminal can substantially confirm. Also in the following embodiments, this point is the same and the description thereof will be omitted as appropriate.

Embodiment 2. FIG.
FIG. 7 is a diagram showing the configuration of the monitoring system in the second embodiment. FIG. 8 is a diagram showing the configuration of the monitoring center of the monitoring system shown in FIG. FIG. 9 is a diagram showing a monitoring table of the monitoring center shown in FIG. FIG. 10 is a diagram showing monitoring data of the first extraction value and the second extraction value extracted by the first extraction unit and the second extraction unit of the monitoring center shown in FIG. 11 and 12 are flowcharts for explaining the operation of the monitoring system shown in FIG.

  In the figure, the same parts as those in the first embodiment are denoted by the same reference numerals and the description thereof is omitted. In the second embodiment, a case will be described in which a recreational basin 17 that stores water of the first river 1 from the monitoring location 11 of the first river 1 by opening the water channel gate 22 is provided. For convenience, it is assumed that the other monitoring points 12, 13, and 14 do not include the reservoir 17. Other parts are the same as those in the first embodiment, and an example using the reservoir 17 will be described in the second embodiment. Furthermore, a pump 23 for returning water from the reservoir 17 to the first river 1 is provided. Further, the water channel gate 22 can receive the opening signal and the closing signal via the public line 100. The pump 23 can receive the operation signal and the stop signal via the public line 100.

  In the monitoring table stored in the monitoring table DB 4 of the monitoring center 3, a reservoir 17 corresponding to the monitoring location 11 is set as shown in FIG. 9. In addition, a second threshold value 211 for determining the danger of the monitoring location 11 is set. In addition, a third threshold value 311 for the water level for determining whether to avoid the danger at the monitoring location 11 is set. Further, a fourth threshold value 417 for the water level for determining the danger of the reservoir 17 is set.

  Specifically, the second threshold value 211 for determining the danger of the monitored location 11 is a value smaller than the first threshold value 111 for determining the evacuation of the monitored location 11. Determining the danger of the monitoring location 11 is a value that sets the timing for discharging the water of the first river 1 from the monitoring location 11 to the reservoir 17. Further, the third threshold value 311 for determining the avoidance of the danger at the monitoring location 11 is a value sufficiently smaller than the second threshold value 211 for determining the danger at the monitoring location 11. The determination of the avoidance of the danger at the monitoring location 11 may be a value that can avoid the danger at the monitoring location 11 of the first river 1, that is, a value that does not cause danger due to flooding of the monitoring location 11. Further, the fourth threshold value 417 is a value that is considered dangerous when the water in the reservoir 17 is full and the water is continuously discharged from the monitoring point 11 of the first river 1 to the reservoir 17 through the waterway gate 22. is there.

  A second shooter 817 that shoots images of the pond 17 is installed in the pond 17. The monitoring center 3 includes a second extraction unit 8. The second extraction unit 8 extracts the water level of the basin 17 as a second extraction value 917 from the video data 617 of the basin 17 of the second photographing unit 817. The data extracted by the second extraction unit 8 is configured in the same manner as the first extraction values 711, 712, 713, and 714 extracted by the first extraction unit 5, as shown in FIG.

  When the first extraction value 711 exceeds the second threshold value 211, the determination unit 7 transmits an open signal to the water channel gate 22 to store the water of the first river 1 in the reservoir 17. Further, when the first extraction value 711 becomes smaller than the third threshold value 311, the determination unit 7 transmits an operation signal to the pump 23 to return the water in the reservoir 17 to the first river 1 and sends a closing signal to the water channel gate 22. Send.

  Moreover, the determination part 7 will transmit the stop signal which stops the pump 23, if the 2nd extraction value 917 becomes 0 (zero). The determination unit 7 transmits a closing signal to the water channel gate 22 when the second extraction value 917 exceeds the fourth threshold value 417.

  Next, the operation of the monitoring system according to the second embodiment configured as described above will be described based on the flowcharts of FIGS. 11 and 12. As in the first embodiment, the monitoring center 3 sends images of the monitoring locations 11, 12, 13, and 14 of the rivers 1 and 2 from the first photographing units 811, 812, 813, and 814 to the reservoir 17. Images are acquired as image data 611, 612, 613, 614, and 617 from the second photographing unit 817 (step ST1 in FIGS. 10 and 11).

  Next, the 1st extraction part 5 makes the water level of each monitoring location 11, 12, 13, 14 from each video data 611, 612, 613, 614 the 1st extraction value 711,712 like the said Embodiment 1. FIG. , 713 and 714 are extracted as shown in FIG. 10 (step ST3 in FIG. 11). Next, the determination part 7 extracts the 2nd threshold value 211 as a water level for determining the danger of the monitoring location 11 which has the reservoir 17 from the monitoring table shown in FIG. 9, respectively (step ST20 of FIG. 11). . Next, the determination unit 7 determines whether or not the first extraction value 711 extracted by the first extraction unit 5 exceeds the second threshold value 211 (step ST21 in FIG. 11).

  Next, an open signal is transmitted to the waterway gate 22 of the reservoir 17 associated with the monitoring location 11 determined to exceed the second threshold 211 (step ST22 in FIG. 11). Then, storage of the water in the first river 1 from the monitoring location 11 of the first river 1 to the reservoir 17 is started via the water channel gate 22.

  Next, the determination unit 7 extracts, from the monitoring table shown in FIG. 9, the third threshold 311 as the water level for determining the avoidance of danger in the monitoring location 11 having the reservoir 17 (step ST23 in FIG. 11). ). Next, the determination unit 7 determines whether or not the first extraction value 711 extracted by the first extraction unit 5 is smaller than the third threshold 311 (step ST24 in FIG. 11).

  Next, if it determines with it being smaller than the 3rd threshold value 311, a closure signal will be transmitted to the waterway gate 22 of the reservoir 17 accompanying the monitoring location 11 (step ST25 of FIG. 11). Furthermore, an operation signal is transmitted to the pump 23 that returns the water in the reservoir 17 associated with the monitoring location 11 to the first river 1 (step ST26 in FIG. 11). Therefore, the discharge of water from the reservoir 17 to the first river 1 is started via the pump 23.

  Next, the second extraction unit 8 extracts the water level of the reservoir 17 from the video data 617 as a second extraction value 917 as shown in FIG. 10 (step ST27 in FIG. 11). Next, it is determined whether or not the second extraction value 917 is 0 (step ST28 in FIG. 11). Next, when it is determined that the second extraction value 917 is 0, a stop signal is transmitted to the pump 23 (step ST29 in FIG. 11), and the pump 23 is stopped. In addition, 0 refers to a value determined when it is not necessary to discharge water when the substantial water level of the basin 17 is 0 or as the basin 17.

  Further, another operation after the risk determination is performed in step ST21 in FIG. 11 will be described. Next, the determination unit 7 extracts the fourth threshold value 417 as the water level for determining the risk of the reservoir 17 from the monitoring table shown in FIG. 9 (step ST30 in FIG. 11). Next, the second extraction unit 8 extracts the water level of the reservoir 17 from the video data 617 as a second extraction value 917 as shown in FIG. 10 (step ST31 in FIG. 11).

  Next, the determination unit 7 determines whether or not the second extraction value 917 extracted by the second extraction unit 8 exceeds the fourth threshold value 417 (step ST32 in FIG. 11). Next, a closing signal is transmitted to the waterway gate 22 of the reservoir 17 associated with the monitoring location 11 determined to exceed the fourth threshold value 417 (step ST25 in FIG. 11). Therefore, the storage of water from the first river 1 to the reservoir 17 is stopped. It is possible to prevent water from overflowing from the basin 17 and structural problems of the basin 17 from occurring.

  Moreover, since the flowchart of each portable terminal 15 and 16 is the same as that of the said Embodiment 1, the description is abbreviate | omitted suitably. Here, it is determined that the GPS position information 815 of the mobile terminal 15 is in the distribution area 511 as in the first embodiment. Therefore, the determination unit 7 transmits the video data 617 of the reservoir 17 to the portable terminal 15 that has been determined to exist within the distribution area 511.

  According to the monitoring system of the second embodiment configured as described above, the same effect as that of the first embodiment is obtained, and the monitoring table database includes a second threshold value of the water level for determining the danger of the monitoring point, In addition, a reservoir that stores river water from the monitoring location by opening the channel gate is set in association with the monitoring location, and the determination unit turns the river water into the reservoir when the first extraction value exceeds the second threshold. Since the open signal is transmitted to the waterway gate for storage, the river water can be easily stored in the reservoir.

  Further, in the monitoring table database, the third threshold value of the water level for determining the avoidance of the danger at the monitoring location is set in association with the monitoring location, and the determination unit transmits the opening signal to the waterway gate and then performs the first extraction. When the value is smaller than the third threshold value, the operation signal is transmitted to the pump for returning the water in the reservoir to the river and the closing signal is transmitted to the waterway gate, so that the management of the water in the reservoir can be simplified.

  In addition, the monitoring table database includes a second image capturing unit that captures images of the recreational pond and a second extraction unit that extracts the water level of the recreational pond as a second extracted value from the image of the recreational pond. The fourth threshold value for determining the water level is set in association with the monitoring location, and the determination unit transmits a release signal to the waterway gate, and when the second extracted value exceeds the fourth threshold value, the closure signal is supplied to the waterway gate. Can be used to ensure the safety of the reservoir.

  In the figure, the same parts as those in the above embodiments are denoted by the same reference numerals, and description thereof is omitted. In the third embodiment, the retaining wall 18 is a component that constitutes the basin 17 of the monitoring location 11 of the first river 1. The second imaging unit 818 captures an image of the retaining wall 18 of the reservoir 17. When the retaining wall 18 is large, it is conceivable that a plurality of second photographing units 818 cope with it as shown in FIG. As shown in FIG. 14, the monitoring center 3 stores video data 618 captured by the second imaging unit 818 and comparison data 918 for comparison with the video data 618.

  Next, the operation of the monitoring system according to Embodiment 3 configured as described above will be described based on the flowchart of FIG. The monitoring center 3 starts monitoring the retaining wall 18 of the reservoir 17 (step ST40 in FIG. 15). Next, the video data 618 photographed by the second photographing unit 818 is periodically input (step ST41 in FIG. 15). Next, the comparison data 918 and the current video data 618 are compared to determine whether the retaining wall 18 is cracked or depressed (step ST42 in FIG. 15). If the comparison data 918 is not stored, the determination is cancelled.

  If it is determined that the retaining wall 18 is cracked or depressed, a danger signal is transmitted to the portable terminal 15 having GPS position information 815 in the distribution area 511 (step ST44 in FIG. 15). The danger signal is composed of at least one of a voice signal, a vibration signal, a message signal, and an optical signal. Further, the data on the location and degree of cracks and depressions is transmitted to the portable terminal 15 (step ST45 in FIG. 15). The video data 618 is stored as comparison data 918 (step ST43 in FIG. 15).

  According to the monitoring system of the third embodiment configured as described above, the same effects as those of the above-described embodiments can be obtained, and the determination unit determines the presence or absence of a dangerous spot from the image of the reservoir. If it is determined that there is a dangerous place, the danger signal is transmitted to the portable terminal having GPS position information in the distribution area, so that the dangerous signal can be transmitted to the portable terminal in a place where it is necessary to know the danger.

  Further, since the danger signal is at least one of a voice signal, a vibration signal, a message signal, and an optical signal, the portable terminal can easily acquire and check the danger signal.
