  The observation stations 11-1 to 11-n are connected to water level gauges 12-1 to 12-n and rainfall gauges 13-1 to 13-n to detect river water level data and rainfall data. . The observation stations 11-1 to 11-n include collecting units 14-1 to 14-n that collect water level data and rainfall data, and lines (in this case, a wireless line is shown, but a wired line may be used) 15-1 The transmitter / receivers 16-1 to 16-n that communicate with the telemeter collecting device 20 via 15-n are provided, and the collecting units 14-1 to 14-n perform polling from the telemeter collecting device 20. The data is received and collected, and this data is transmitted from the transmission / reception units 16-1 to 16-n to the telemeter collection device 20.

  The telemeter collection device 20 includes a transmission / reception unit 21 that communicates with the observation stations 11-1 to 11-n, and a collection management unit 22 that performs polling command management based on an instruction from the processing device 30. ing. In this embodiment, the observation stations 11-1 to 11-n are processed by the single telemeter collection device 20, but when n is a large number, a plurality of telemeter collection devices are provided. A configuration is adopted in which the observation stations 11-1 to 11-n are divided into several groups for corresponding processing.

  The processing device 30 is configured by, for example, a personal computer, and is connected to a position information storage unit 31, a history information storage unit 32, and a terrain / basin information storage unit 33. The processing device 30 obtains radar rainfall / rainfall prediction data from the Japan Meteorological Agency 41 or the like via the Internet at intervals of 10 minutes, and obtains image information from several monitoring cameras 42 installed near the river via a line or the like. It has gained. Further, the processing device 30 obtains atmospheric pressure / temperature from several atmospheric pressure / temperature notification units (observation stations, etc.) 43 via lines, for example, at intervals of 10 minutes, and several seismic intensity notification units (observation stations, etc.). ) Seismic intensity information is obtained from 44 via the line. The processing device 30 obtains position information and instruction information regarding polling start and polling interval change from several mobile phones 45 with GPS (position information sending function) via a telephone line. Notification of dam discharge warning information is obtained from several dam discharge notification sections (dam management offices, etc.) 46 for the dams.

  The position information storage unit 31 includes tables TB1 to TB5 as shown in FIG. In the table TB1, the position information of the positions where the observation stations 11-1 to 11-n are installed is stored in longitude and latitude corresponding to the identification information (ID) of the observation stations 11-1 to 11-n. ing. In the table TB2, position information of the position where each monitoring camera 42 is installed is stored in longitude and latitude in correspondence with the identification information (ID) of each monitoring camera 42. In the table TB3, corresponding to the identification information (ID) of each atmospheric pressure / temperature notification unit 43, position information of the position where each atmospheric pressure / temperature notification unit 43 is installed is stored in longitude and latitude. . In the table TB4, corresponding to the identification information (ID) of each seismic intensity notification unit 44, position information of the position where each seismic intensity notification unit 44 is installed is stored in longitude and latitude. In the table TB5, the position information of the position where each dam is installed is stored in longitude and latitude corresponding to the identification information (ID) of each dam.

  In the history information storage unit 32, for example, as shown in FIG. 4, history information is tabulated for each flood ID (identification number). This history information table gives a flood ID (identification number) for each case when a flood occurs or a flood warning is issued, and shows the rainfall and water level measured at the relevant observation station. The data is stored.

  For example, as shown in FIG. 5, the terrain / basin information storage unit 33 stores position information regarding the XX river, the XX river basin A, the XX river basin B, and the like based on the terrain. . For example, with respect to an area of 1 km square, position information and basin information based on latitude and longitude are stored as a set as shown in an enlarged manner. The basin information is information as to whether each 1 km square area is the basin A, the basin B, or does not belong to any basin.

  The processing device 30 includes an acquisition unit 35 and a control unit 36. In particular, the control means 36 sets a predetermined time (1 hour in this case) from this time, for example, at the normal time when the water level data, rainfall data, etc. are displaced, for example, at 12:00 on the system startup date. Processing for collecting data from the observation stations 11-1 to 11-n is performed by polling at intervals. The acquisition means 35 acquires information that is the basis for determining polling start change from other than the observation stations 11-1 to 11-n at intervals shorter than the normal polling interval, continuously, or at an arbitrary timing. To do. Here, the stations other than the observation stations 11-1 to 11-n refer to the Japan Meteorological Agency, etc. 41, the monitoring camera 42, the atmospheric pressure / temperature notification unit 43, the seismic intensity notification unit 44, the GPS mobile phone 45, and the dam discharge notification unit 46. ing.

  The control means 36 gives a polling instruction to the corresponding observation station to the collection management unit 22 using the polling time management table shown in FIG. That is, the management table of FIG. 6 stores the next polling time and the next polling time corresponding to the observation station ID (identification information).

  The control means 36 constituted by a personal computer or the like executes the flowchart shown in FIG. 7 to set time information for the management table. This operation will be described below. First, 1 is set to the pointer i in the observation station ID column of the management table (S1), and the rainfall data and water level data sent from the i (= 1) -th observation station (for example, ID = K001) are used. It is determined whether normal polling is performed by detecting whether at least one of the two exceeds a predetermined threshold (S2, S3). In this step S3, if at least one of the rainfall data and the water level data exceeds a predetermined threshold value, the process branches to NO, changes the polling interval according to a predetermined rule, and sends the time information to the next time field and the next time field. Is written (S4). For example, if the rule is to change the interval to 10 minutes, the time information 10 minutes after the previous time is written to the next time field, and the time information 10 minutes after the next time field is written to the time field one after another. .

  On the other hand, if it is determined in step S3 that normal polling is to be performed, the process branches from step S3 to YES, and time information, for example, one hour after the previous polling time, is input to the next time column to perform normal polling. Further, the time information one hour after the next time field is written to the time field one after another (S5). Then, 1 is added to the pointer i after the end of the process of step S5 or the end of the process of step S4. (S6) It is determined whether the value of the pointer i exceeds the maximum entry (11 in the example of FIG. 6) (S7). If not (for example, if i = 2), i ( = 2) Using the rainfall data and the water level data sent from the first observation station (for example, ID = K002), it is detected whether at least one of them exceeds a predetermined threshold. Proceeds to determining S2, S3 whether a more normal polling.

  On the other hand, if it is determined in step S7 that the maximum entry is exceeded (for example, if i = 12), the process returns to step S1 to set 1 to the pointer i in the observation station ID column of the management table (S1). Whether or not to use normal polling by detecting whether at least one of them exceeds a predetermined threshold, using rainfall data and water level data sent from the i (= 1) -th observation station (for example, ID = K001) Processing of steps S2 and S3 for determination is performed.

  Based on the information acquired by the acquisition means 35 in addition to the processing in FIG. 7, the control means 36 performs polling start and interval change determination according to the flowchart shown in FIG. 8, so start polling with reference to FIG. The operation for determining the interval change will be described. The process of this flowchart is started each time data is acquired by the acquisition unit 35 and is transferred to the control unit 36. The control unit 36 uses the data acquired by the acquisition unit 35 to determine whether it is a start or interval change by comparing it with a threshold value (S11, S12).

  When starting and changing the interval in step S12, the position information stored in the position information storage unit 31 of FIG. 3 or the basin information stored in the terrain / basin information storage unit 33 is used. The start of polling and the observation station to which the interval change should be applied are specified (S13), and then time information is written in the next time column and the next time column corresponding to the required observation station in the management table shown in FIG. Thus, polling start and polling interval are changed (S14). For example, if it is decided to start polling and change the polling interval to 10 minutes based on the processing by the control means 36, the time information after the margin time from the current time is written to the next time field, and further this next time field The time information 10 minutes after is written in the time column one after another. If the start or interval change is not performed in step S12, the process branches to NO in step S12 and ends.

  FIG. 9 shows processing according to a specific example in which the operation in FIG. 8 is performed. The processes 1 to 6 shown in FIG. 9 do not mean that the processes 1 to 6 are performed in this order. The processes 1 to 6 are executed according to the type of data acquired by the acquisition unit 35.

  First, when the acquisition unit 35 acquires radar rainfall / rainfall prediction data from the Japan Meteorological Agency or the like 41, the process 1 is to determine polling start and interval change based on this. The radar rainfall / rainfall prediction data is provided with radar rainfall / rainfall prediction data for each 1 km square mesh. For example, for each mesh in the map area of FIG. When the position information of the detected mesh exceeds the position information of the observation station in the table TB1 of the position information storage unit 31 shown in FIG. 3 or the position information is within a certain distance, polling is performed for the observation station Start and change the interval. In the case of this polling start and interval change, for example, if it is decided to start polling and change the polling interval to 10 minutes based on the processing by the control means 36, time information after the margin time from the current time Is written in the next time field, and time information 10 minutes after the next time field is written in the next time field.

  Further, referring to the terrain / basin information storage unit 33, polling start and interval change are similarly performed for all observation stations existing in the basin to which the observation station related to polling start and interval change belongs or for downstream observation stations. Can also be done. Further, in the above, it is also possible to provide some of the above-mentioned threshold values and control which observation station performs the polling start and interval change in accordance with which threshold value is exceeded. In this way, the control means 36 determines the area where polling should be started or the polling interval should be changed based on the information acquired by the acquisition means 35, identifies the observation station corresponding to the area, and polls the observation station Is to execute.

  In the process 2, when the acquisition unit 35 acquires the image information sent from the monitoring camera 42, the image processing is performed based on the acquired image information, the rain condition or the river condition is detected, and the polling start and the interval change are determined. That's it. As image processing, it is determined that there is rainfall when the brightness level is increased compared to the image information in the normal state or the area of the puddle can be detected by utilizing the fact that reflection occurs due to rain, or the river In this case, the water level is detected by image processing, and it is determined that there is rainfall when an increase is observed from the water level in the normal image information.

  Then, using the position information of the table TB1 of the position information storage unit 31 shown in FIG. 3 and the position information of the monitoring camera 42 in the table TB2, the observation information that the corresponding monitoring camera 42 and the position information match or are within a certain distance. The station is detected, and polling is started and the interval is changed for the observation station. In this case, the information is written in the corresponding next time field, and further written in the time field one after another. Furthermore, the process for obtaining the target observation station with reference to the terrain / basin information storage unit 33 can be performed in the same manner as the process 1.

  The process 3 is to detect a case where the rainfall has been matched or similar based on the flood history information accumulated in the history information storage unit 32, and to start polling of the corresponding observation station and determine the interval change. . The history of each observation station 11-1 to 11-n from the present time to a predetermined time ago and stored in the history information storage unit 32 as a table for each flood ID (identification number) as shown in FIG. Compare the historical information at the time of flood occurrence or flood warning issuance, and start polling for the observation stations stored in the table when they are similar, such as when they match or match at a predetermined time And change the interval. In this case, the information is written in the corresponding next time field, and further written in the time field one after another. Furthermore, the process for obtaining the target observation station with reference to the terrain / basin information storage unit 33 can be performed in the same manner as the process 1.

  Process 4 is to start polling and change the interval when the atmospheric pressure / temperature notified by the atmospheric pressure / temperature notification unit 43 changes more than a predetermined amount compared to the previous time. In this process 3, corresponding to the identification information (ID) of the corresponding atmospheric pressure / temperature notification unit 43 based on the table TB3, the corresponding atmospheric pressure is referred to with reference to the position information of the position where each atmospheric pressure / temperature notification unit 43 is installed. The position information of the position where the temperature notification unit 43 is installed is obtained, the position information of the observation station is obtained from the table TB1, and compared with this to detect the coincidence or the position information within a certain distance, Start polling and change interval for observation stations.

  Alternatively, when the seismic intensity is notified by the seismic intensity notification, the polling is started and the interval is changed. In this case, corresponding to the identification information (ID) of the corresponding seismic intensity notifying unit 44 based on the table TB4, the corresponding seismic intensity notifying unit 44 is referred to by referring to the position information of the position where each seismic intensity notifying unit 44 is installed. Is obtained, and is compared with the position information of the observation station obtained from the table TB1 to detect the coincidence or the position information within a certain distance, and start polling for the observation station. And change the interval. In the above case, the corresponding time is written in the next time field, and further written in the time field one after another. Furthermore, the process for obtaining the target observation station with reference to the terrain / basin information storage unit 33 can be performed in the same manner as the process 1.

  Process 5 is to start polling and change the interval when a polling start / interval change instruction mail is sent together with the position information from the GPS mobile phone 45. The position information sent from the GPS mobile phone 45 and the position information of the observation station obtained from the table TB1 are compared, and the coincidence or the position information within a certain distance is detected, and polling starts for the observation station And change the interval. Also in this case, the information is written in the corresponding next time field, and further written in the time field one after another. Furthermore, the process for obtaining the target observation station with reference to the terrain / basin information storage unit 33 can be performed in the same manner as the process 1.

  Process 6 is to start polling and change the interval when a water discharge warning is notified from the dam water discharge notification unit 46. Based on the table TB5, corresponding to the identification information (ID) of the corresponding dam, the position information of the position where each dam is installed is referred to to obtain the position information, and the position information of the observation station obtained from the table TB1 In comparison with the above, a case where the coincidence or the position information is within a certain distance is detected, and polling is started and the interval is changed for the observation station. In the above case, the corresponding time is written in the next time field, and further written in the time field one after another. Furthermore, the process for obtaining the target observation station with reference to the terrain / basin information storage unit 33 can be performed in the same manner as the process 1.
