Description

  The present invention relates to a flood control information distribution system that collects rainfall information and river water level information and performs river management, and a distribution method thereof.

  As a conventional flood control information distribution system, a system as shown in FIG. 4 is known. As shown in FIG. 4, the conventional flood control information distribution system includes an observation device 100 (five in the drawing) installed for each observation target river to collect rainfall information and river level information, that is, flood control information. The monitoring device 100 is configured by a host server 200 that collectively manages flood control information. The monitoring device 100 and the host server 200 are connected via a communication network N. The upper server 200 is installed in the Japan Meteorological Agency and / or a prefectural office.

  As shown in FIG. 4, the flood control information collecting method of the flood control information distribution system configured as described above first transmits data distribution request information t to each observation device 100 from the upper server 200 via the communication network N. To do. Then, according to the data distribution request information t, each observation device 100 transmits each flood control information t1 observed via the communication network N to the upper server 200. Thereby, each flood control information t1 observed by each observation device 100 is managed by the host server 200 in a lump.

  By the way, the flood control information distribution system as described above has the following problems. That is, in the flood control information distribution system as described above, each observation device 100 transmits each observed flood control information t1 to the upper server 200 in accordance with the data distribution request information t of the upper server 200. The processing of the upper server 200 ends by transmitting the data distribution request information t for each observation device 100 and receiving the flood control information t1 for each observation device 100 that is the transmission destination of the data distribution request information t. It is to do. Therefore, the more rivers to be observed, the longer it takes to complete the distribution, which is why real-time performance is lacking, and the rainfall information and water level of the rivers to be observed have been increased against local torrential rains that have been increasing in recent years. There was a problem that information could not be grasped accurately.

  In addition, when the communication between the host server 200 and the observation apparatus 100 is wireless communication in particular, depending on the installation environment of the observation apparatus 100, there is often a state in which distribution is impossible. Since then, distribution to the upper server 200 has not been possible. For this reason, there is a problem that an operator has to go to the place where the observation apparatus 100 that has become undeliverable is installed, reset the observation apparatus 100, and restore distribution to the upper server 200.

  Since the host server 200 transmits the data distribution request information t for each observation device 100 via the communication network N, it is necessary to assign an address (IP address) for each device to each observation device 100. There is also a problem that the running cost increases.

  Therefore, in view of the above problems, the present invention accurately grasps the rainfall amount information and water level information of the observation target river, and further restores the distribution to the upper server without human intervention as much as possible even if the distribution becomes impossible, and An object of the present invention is to provide a flood control information distribution system and a distribution method thereof that can reduce running costs.

  Next, effects of the present invention will be described with reference numerals in the drawings. In addition, although the code | symbol in a parenthesis attaches the referential mark of embodiment mentioned later, this invention is not limited to this.

  First, according to the flood control information distribution system according to the first aspect of the invention, the measurement sensor (3) measures the rainfall and / or water level data of the river to be observed, and the measured data is used as data acquisition means (rain data acquisition). 51, water level data acquisition unit 53), and the acquired data is sampled by sampling means (rainfall data sampling unit 52, first water level data sampling unit 54, second water level data sampling unit 55), The sampled data is distributed to the upper server (2) at predetermined time intervals by the distribution means (communication unit 57). Therefore, it is possible to distribute the data to the upper server (2) every predetermined time without a distribution request from the upper server (2). Therefore, according to the present invention, it is possible to distribute the situation of the observation target river in real time, and it is possible to accurately grasp the rainfall information and the water level information of the observation target river.

  Further, according to the present invention, the host server (2) only needs to receive the delivery from the delivery means (communication unit 57), so the server load is reduced and the communication speed is improved. Therefore, it is possible to grasp the rainfall information and water level information of the observation target river in real time.

  Further, according to the present invention, when the distribution monitoring unit (communication monitoring unit 58) monitors the undeliverable state for a predetermined time, the distribution recovery unit (communication recovery unit 60) restarts the observation device (1). The distribution means (communication unit 57) is urged to recover the distribution to the upper server (2). Therefore, even if the observation apparatus (1) and the upper server (2) cannot be distributed, the distribution to the upper server (2) can be automatically recovered, and therefore the upper server (2) without human intervention as much as possible. ) Can be recovered.

  Furthermore, according to the present invention, since the data is distributed to the upper server (2) every predetermined time without a distribution request from the upper server (2), the address for each observation device as in the conventional system. (IP address) need not be assigned, and the running cost can be reduced.

  On the other hand, according to the invention of claim 2, the data acquired by the data acquisition means (rainfall data acquisition section 51, water level data acquisition section 53) every predetermined time is sampled by the sampling means (rainfall data sampling section 52, first water level data). Since sampling is performed by the sampling unit 54 and the second water level data sampling unit 55), it is possible to obtain the most suitable hourly data that the observer wants to know most, and furthermore, the water level and rainfall conditions of the observation target river The sampling contents can be freely changed according to the above.

  Furthermore, according to the invention of claim 3, the distribution status at the time of data distribution to the upper server (2) is monitored by the distribution monitoring means (communication monitoring unit 58), and the data distribution to the upper server (2) fails. Then, the undelivered data storage means (undistributed data storage unit 59) stores the undelivered data that failed to be distributed. When the distribution unit (communication unit 57) performs data distribution again to the upper server (2), the undistributed data stored in the undistributed data storage unit (undistributed data storage unit 59) is also stored in the upper unit. Deliver to server (2). Therefore, according to the present invention, even if data cannot be distributed to the upper server (2) due to some distribution trouble, the distribution trouble cannot be distributed to the upper server (2) after the distribution trouble is resolved. Since the data is distributed again to the upper server (2), it is possible to prevent a situation in which data stored in the upper server (2) is lost.

  On the other hand, according to the invention of claim 4, since the flood control information distribution system according to claim 1 is expressed as the invention of the method, the same operational effects are produced.

It is a schematic block diagram of the flood control information delivery system which concerns on this invention. It is a block diagram of the flood control information distribution system. It is a flowchart figure which shows one usage example of the same flood control information delivery system. It is a schematic block diagram of the conventional flood control information delivery system.

  Hereinafter, an embodiment of a flood control information distribution system according to the present invention will be specifically described with reference to FIGS. First, the configuration of the flood control information distribution system according to the present embodiment will be described with reference to FIGS. 1 and 2.

  As shown in FIG. 1, the flood control information distribution system according to the present embodiment has an observation device 1 (five in the figure) installed for each observation target river to collect rainfall information and river level information, that is, flood control information. And an upper server 2 that collectively manages flood control information collected by these observation devices 1. These observation devices 1 are connected to the upper server 2 via the communication network N, and each of the observation devices 1 receives the collected flood control information p via the communication network N every predetermined time. Deliver to 2. The upper server 2 is installed in, for example, the Meteorological Agency and / or a prefectural office.

  The flood control information distribution system configured as described above will be described in more detail with reference to FIG. First, the observation device 1 will be described in more detail. The observation device 1 includes a measurement sensor 3, an A / D converter 4, and a signal processing device 5. The measurement sensor 3 includes a rain gauge 30 that measures the rainfall amount of the observation target river and a water level gauge 31 that measures the water level of the observation target river. The rain gauge 30 outputs an analog signal corresponding to the measured rainfall to the A / D converter 4, and the water level gauge 31 outputs an analog signal corresponding to the measured water level to the A / D converter 4. The A / D converter 4 converts the analog signal output from the rain gauge 30 into a digital signal and outputs the digital signal to the signal processor 5 and the water level gauge 31. An A / D conversion unit 41 that converts an analog signal into a digital signal and outputs the signal to the signal processing device 5 is configured.

  On the other hand, the signal processing device 5 is composed of, for example, a general-purpose PC (Personal Computer), and is configured as shown in FIG. That is, the signal processing device 5 includes a central control unit 50 including a CPU and the like, a rainfall data acquisition unit 51, a rainfall data sampling unit 52, a water level data acquisition unit 53, a first water level data sampling unit 54, and a second The water level data sampling unit 55, the storage unit 56, the communication unit 57, the communication monitoring unit 58, the undistributed data storage unit 59, and the communication recovery unit 60 are configured. The rainfall data acquisition unit 51 acquires a digital signal corresponding to the measured rainfall converted from an analog signal to a digital signal by the A / D conversion unit 40, and the rain data sampling unit 52 is the rain data acquisition unit 51. The digital signal acquired in (1) is integrated (sampled) every predetermined time (for example, every minute).

  The water level data acquisition unit 53 acquires a digital signal corresponding to the measured water level converted from an analog signal to a digital signal by the A / D conversion unit 41, and the first water level data sampling unit 54 stores the water level. Based on the digital signal acquired by the data acquisition unit 53, a process of calculating (sampling) an average value every predetermined time (for example, every 6 seconds) is performed. And the 2nd water level data sampling part 55 performs the process which calculates (samples) the average value for every predetermined time (for example, every minute) further based on the average value calculated in the said 1st water level data sampling part 54 . In the present embodiment, an example in which two-stage sampling is performed with the first water level data sampling unit and the second water level data sampling unit is shown. However, when measuring the water level of a river whose water surface is not constant due to wave winds or the like, it is preferable to perform the two-stage sampling because the two-stage sampling improves the accuracy of the water level data as described above. In addition, since the rain data sampling unit 52, the first water level data sampling unit 54, or the second water level data sampling unit 55 can be sampled at predetermined time intervals, the optimum time that the observer wants to know most is obtained. Each data can be acquired, and furthermore, the sampling contents can be freely changed according to the water level / rainfall situation of the observation target river.

  On the other hand, the storage unit 56 stores the signal accumulated by the rainfall data sampling unit 52, stores the average value calculated by the first water level data sampling unit 54, and further stores the second water level data sampling unit 55. It consists of a database that stores the average value calculated in (1). The format of data stored in the storage unit 56 is a text format or the like.

  The communication unit 57 can be connected to the communication network N by communication means such as a wireless LAN, a wired LAN, or dial-up, and distributes data to the upper server 2 at predetermined time intervals (for example, every minute). To do.

  On the other hand, the communication monitoring unit 58 regularly or constantly monitors the distribution status of data distributed from the communication unit 57 to the upper server 2. In addition, the undelivered data storage unit 59 cannot be distributed via the communication network N between the communication unit 57 and the upper server 2, and when the situation is monitored by the communication monitoring unit 58, the communication unit 57 cannot be distributed. The undelivered data that could not be distributed to the upper server 2 is stored.

  Further, the communication recovery unit 60 monitors the undeliverable situation with the communication monitoring unit 58, and when the state continues for a predetermined time, the signal processing device 5 itself is restarted and the communication unit 57 is in communication network N. This is intended to promote the recovery of distribution to the upper server 2 via.

  On the other hand, the host server 2 includes a communication unit 20 and a storage unit 21. The communication unit 20 can be connected to the communication network N by communication means such as a wireless LAN, a wired LAN, or dial-up. The storage unit 21 includes a database that stores data distributed from the communication unit 57 of the observation apparatus 1.

  Next, an example of use of the flood control information distribution system configured as described above will be described with reference to FIG. First, the rainfall / water level of the observation target river is measured using the measurement sensor 3. That is, the rainfall amount of the observation target river is measured by the rain gauge 30 (step S1A), while the water level of the observation target river is measured by the water level gauge 31 (step S1B).

  Then, the rainfall measured by the rain gauge 30 is converted into a digital signal by the A / D converter 40 of the A / D converter 4 and output to the signal processing device 5. The digital signal output to the signal processing device 5 is acquired by the rainfall data acquisition unit 51 and is output to the rainfall data sampling unit 52 via the central control unit 50. The rainfall data sampling unit 52 integrates the digital signals acquired by the rainfall data acquisition unit 51 every minute (step S2A).

  On the other hand, the water level measured by the water level gauge 31 is converted into a digital signal by the A / D converter 41 of the A / D converter 4 and output to the signal processing device 5. And the digital signal output to this signal processing apparatus 5 is acquired by the water level data acquisition part 53 every second (step S2B).

  And the signal acquired in this way by the water level data acquisition part 53 is output to the 1st water level data sampling part 54 via the central control part 50, and the 1st water level data sampling part 54 is the water level data acquisition part 53. Based on the output signal, an average value every 6 seconds is calculated (step S3B).

  On the other hand, the 1st water level data sampling part 54 outputs to the memory | storage part 56 via the central control part 50 for every calculation of the said 6 second average value, and the memory | storage part 56 is the data for every calculation of the 6 second average value. Is stored (step S4B). Further, the first water level data sampling unit 54 outputs the second water level data sampling unit 55 to the second water level data sampling unit 55 via the central control unit 50 every time the 6-second average value is calculated. Based on the average value every 6 seconds calculated by the water level data sampling unit 54, the average value every minute is calculated (step S5B).

  As described above, the integrated value per minute sampled by the rainfall data sampling unit 52 and the average value per minute sampled by the second water level data sampling unit 55 are respectively set via the central control unit 50. The data is output to the storage unit 56 and stored in the storage unit 56 (step S10). After that, the central control unit 50 stores the data stored in the storage unit 56 (the integrated value every minute accumulated by the rainfall data sampling unit 52 and the every minute calculated by the second water level data sampling unit 55). The communication unit 57 is instructed to distribute the average value), and the communication unit 57 reads out the data stored in the storage unit 56 in accordance with the instruction, and transmits the data (that is, the flood control information p) at intervals of 1 minute. N is distributed to the host server 2 via N (step S11). In the present embodiment, the average value every 6 seconds calculated by the first water level data sampling unit 54 is not distributed to the upper server 2, but may be distributed as a matter of course.

  By the way, the distribution is monitored by the communication monitoring unit 58, and the distribution status as to whether or not the data distribution to the upper server 2 is successful is monitored (step S12). If data distribution to the upper server 2 fails (step S12: NO), the communication monitoring unit 58 outputs the status to the central control unit 50. Thereby, the central control unit 50 adds 1 to the time counter Timer_cnt (step S13). Then, when notified from the central control unit 50 that the distribution has failed, the undistributed data storage unit 59 stores the undistributed data that has failed to be distributed (step S14).

  Next, the central control unit 50 notifies the communication recovery unit 60 that the distribution has failed, so that the communication recovery unit 60 determines whether the time counter Timer_cnt is greater than or equal to a predetermined value (for example, 5 or greater). Is determined (step S15). If it is equal to or greater than the predetermined value, it can be determined that a predetermined time has elapsed since the distribution failed (that is, the distribution is impossible) (step S15: YES), and therefore the communication recovery unit 60 restarts the signal processing device 5 itself. It starts (step S16) and prompts the communication unit 57 to restore distribution to the upper server 2. Thereby, the communication part 57 performs the process of step S11 again. At that time, undelivered data stored in the undelivered data storage unit 59 is also distributed to the upper server 2.

  On the other hand, if it is not equal to or greater than the predetermined value, it can be determined that the predetermined time has not elapsed since the distribution failed (that is, the distribution is impossible) (step S15: NO), the communication recovery unit 60 performs the process of step S16. Without urging, the communication unit 57 is urged to restore the distribution to the upper server 2. Thereby, the communication part 57 performs the process of step S11 again. At that time, undelivered data stored in the undelivered data storage unit 59 is also distributed to the upper server 2.

  Thus, if undelivered data stored in the undelivered data storage unit 59 is also distributed to the upper server 2, some communication failure occurs between the communication unit 57 and the upper server 2, and distribution is impossible. Even if the data becomes undeliverable, the data stored in the upper server 2 can be prevented from being lost because the data when the distribution is impossible is distributed to the upper server 2 after the recovery of distribution.

  On the other hand, if the data distribution to the upper server 2 is successful (step S12: YES), the data is stored in the storage unit 21 of the upper server 2 (step S17). Then, the central control unit 50 sets 0 to the time counter Timer_cnt (step S18).

  Therefore, according to the present embodiment, the measurement sensor 3 measures the rainfall and / or water level data of the observation target river, and the measured data is acquired by the rainfall data acquisition unit 51 and / or the water level data acquisition unit 53. Then, the acquired data is sampled by the rainfall data sampling unit 52 and / or the first water level data sampling unit 54 and the second water level data sampling unit 55, and the sampled data is sampled by the communication unit 57 at predetermined intervals. Delivered to the server 2. Therefore, the data can be distributed to the upper server 2 every predetermined time without a distribution request from the upper server 2. Therefore, according to the present embodiment, it is possible to distribute the state of the observation target river in real time, and it is possible to accurately grasp the rainfall information and the water level information of the observation target river. Further, since the upper server 2 only receives the distribution from the communication unit 57, the server load is reduced and the communication speed is improved. Therefore, according to the present embodiment, it is possible to grasp rainfall information and water level information of the observation target river in real time.

  Furthermore, according to the present embodiment, when the communication monitoring unit 58 monitors the undeliverable state for a predetermined time, the communication recovery unit 60 restarts the observation device 1 (signal processing device 5), and the communication unit 57 The distribution recovery to the upper server 2 is urged. Therefore, even if the observation apparatus 1 and the upper server 2 cannot be distributed, the distribution to the upper server 2 can be automatically recovered, so that the distribution to the upper server 2 can be recovered without human intervention as much as possible. Can do.

  Further, according to the present embodiment, since the data is distributed to the upper server 2 at a predetermined time without a distribution request from the upper server 2, the address (IP address) for each observation device as in the conventional system. ) Is not necessary, and the running cost can be reduced.

  In the present embodiment, only one upper server 2 is illustrated, but it is needless to say that a plurality of servers can be installed. If a plurality of devices are installed, the same data can be transmitted to a plurality of higher-order servers in consideration of the safety of data distributed from the observation device 1 (for example, data loss).
