Description

  The present invention relates to a river predicted water level data creation system that creates predicted water level data relating to a predicted water level at least at a predetermined time or a specified time in a river that is affected by fluctuations in the water level due to water discharge from a hydroelectric power plant. The present invention relates to a river prediction water level data creation system that creates prediction water level data that is useful information for the river.

  In hydroelectric power plants, water is discharged into rivers and the like in order to operate generators by hydropower. The water discharge accompanying the operation of this hydroelectric power plant changes the water level, flow rate, etc. of the river, and in particular, downstream of the river, it causes water to increase when a considerable amount of time has passed.

  Such a hydropower plant operation (water discharge) plan cannot be known without inquiring directly from the responsible control station, and the contact information is also very difficult to understand. Moreover, it is very difficult for those who enjoy leisure activities such as fishing in the river to predict in advance that the river environment such as the water level of the river will change due to the discharge of the hydroelectric power plant. Moreover, since the water level fluctuation in the river greatly affects the result of carp fishing, for example, if the water level rises to some extent, the fishing ground must be changed. In addition, sudden flooding of rivers is very dangerous for people at or near riversides.

  In recent years, an emergency information distribution apparatus that distributes emergency information based on disaster information such as floods and earthquakes has been proposed (see, for example, Patent Document 1). It is not possible to predict water level fluctuations, particularly water level fluctuations that will affect carp fishing.

  Hereinafter, the best mode for carrying out the present invention will be described. However, the description of the present embodiment is an exemplification, and the configuration of the present invention is not limited to the following description. FIG. 1 is a system configuration diagram of a river prediction water level data creation system according to an embodiment of the present invention.

  In the river prediction water level data creation system of this embodiment, as shown in FIG. 1, a user terminal 10 and a river prediction water level data creation server 20 are connected via a network 30. Here, the network 30 refers to connection means via a LAN, a dedicated line, or the Internet. Note that the user terminal 10 and the river prediction water level data creation server 20 may be any information communication device having various functions of a general computer, such as a personal computer (PC).

  In addition, the user terminal 10 is preliminarily granted an access right to the river prediction water level data creation server 20, and such a user terminal 10 accesses the river prediction water level data creation server 20, For example, it is possible to designate (select) a river for which prediction of water level fluctuation is desired and a detailed location of the river.

  On the other hand, in the river prediction water level data creation server 20, the rivers that are affected by the water discharge from the hydroelectric power station according to the input data 1 input from the terminal 10 of the user, that is, the data related to the designated river and the designated place. Predicted water level data 2 for predicting water level fluctuations is created, and transmission of the predicted water level data 2 to the user's terminal 10 is executed via the network 30.

  Specifically, the river predicted water level data creation server 20 is connected to a database (DB) 40 that stores various data necessary to create the predicted water level data 2 and the database 40 as shown in the figure. Predicted water level data creating means 50 for creating predicted water level data 2, and in this embodiment, input data obtaining means 60 for obtaining input data 1 inputted at the terminal 10 of the user, and predicted water level Predicted water level data providing means 70 for providing data 2 to the user terminal 10 is provided.

  The database 40 includes operation plan data 41 relating to an operation plan involving water discharge of a hydroelectric power plant, system data 42 relating to a system between a river and a hydroelectric power plant, reference water level data 43 relating to a reference water level at a predetermined location of the river, Is at least stored. Here, the operation plan data 41 is, for example, data indicating an operation plan such as a water discharge start time, a water discharge stop time, and a water discharge amount of the hydroelectric power plant. The system data 42 is the positional relationship between the hydroelectric power plant and the river, specifically, data on one or more hydroelectric power plants that discharge water to one river. The reference water level data 43 is, for example, river level data of a river that is a reference at the time when there is no influence of river discharge.

  In addition to the various data described above, such a database 40 includes, for example, hydroelectric power stations and rivers that are affected by water discharge from them, map data around them, and reference water amounts at predetermined locations on the rivers. Reference water amount data, river geography data relating to river depth and inclination angle, weather forecast data, and the like may be stored. In any case, it is only necessary that the database 40 stores data used as a reference for predicting the water level of the river, and the present invention is not limited to the above.

  Further, in the present embodiment, the database 40 is illustrated as being provided in the river prediction water level data creation server 20, but the present invention is not limited to this, and all or part of the database and the river What is necessary is just to be able to refer to the predicted water level data creation means by connecting to the predicted water level data creation server via a network or the like.

  The input data acquisition means 60 has a function of acquiring (receiving) the input data 1 transmitted from the user terminal 10 via the network 30. Here, the input data 1 is data input by the user via the terminal 10 in the present embodiment. For example, a river (river name or the like) for which the predicted water level data 2 is desired to be acquired, the river Data such as detailed location, date, time or time.

  Further, the predicted water level data providing unit 70 has a function of providing (transmitting) the predicted water level data 2 created by the predicted water level data creating unit 50 described later to the user terminal 10 via the network 30.

  Hereinafter, the predicted water level data creation means 50 will be described. The predicted water level data creating means 50 refers to at least one place of at least one designated river designated based on the input data 1 input by the user via the terminal 10 and the network 30 while referring to the database 40. It has a function of creating predicted water level data 2 relating to the predicted water level at a predetermined time or a specified time.

  Specifically, the predicted water level data creation means 50 identifies a hydroelectric power plant that discharges water to a designated river based on the grid data 42 and performs power generation, and corresponds to the operation plan data 41 of the hydroelectric power plant and the designated river. The reference water level data 43 to be extracted is extracted. Here, the predicted water level data creating means 50 extracts, as the operation plan data 41 to be extracted, water discharge data related to the discharge of the identified hydroelectric power plant, for example, data such as the water discharge amount, the water discharge start time, and the water discharge stop time. Then, the predicted water level data creating means 50 creates the predicted water level data 2 based on the extracted operation plan data 41 and the reference water level data 43.

  In the present invention, when the predicted water level data 2 is created in this way, for example, the number of rivers and locations of the rivers is not limited. Also, the time may be designated, the time zone may be designated, or the predicted water level data 2 at a predetermined time (predetermined time) or time (predetermined time) may be created.

  Here, in this embodiment, an example of the predicted water level data 2 created by the above-described predicted water level data creating unit 50 will be described. FIG. 2 shows an example of the predicted water level data 2. Predicted water level data 2 shown in FIG. 2 is data relating to “XX river” when the discharge start time of “XX power plant” is 10:00 and the discharge stop time is 15:00. Shows the predicted water level at the specified time for each designated place of “Area (A Set)”, “B Point (B Set)”, and “C Point (C Set)” of “Tokoro Drain” Is.

  In such predicted water level data 2, for example, on May 17, the predicted water level of “XX power plant outlet” at 10:00, which is the discharge start time, increases by about 40 cm from the reference water level. The predicted water level at 11:00 (after 1 hour has passed since the time of water discharge) at point A (A set) located downstream from the “power plant outlet” indicates an increase of about 35 cm from the reference water level. On the other hand, on May 17, the predicted water level of “XX power plant outlet” at 15:00, which is the water discharge stop time, decreases by about 40 cm and returns to the reference water level. The predicted water level at 00 (one hour after the water discharge stop time) shows that the predicted water level decreases by about 35 cm and returns to the reference water level. In addition, on May 18, there is no operation plan for “XX power plant”, indicating that there is no change in water level throughout the day.

  Here, the operation of the above-described river prediction water level data creation system will be described. FIG. 3 is a diagram showing a communication sequence of the river prediction water level data creation system according to the embodiment of the present invention. First, the input data 1 input at the user's terminal 10, here, the data relating to the river name, the designated place of the river, and the date are transmitted to the river prediction water level data creation server 20 (step S 1), and the input data acquisition means 60. Acquires the input data 1 (step S2). Next, based on the input data 1, the predicted water level data creation means 50 extracts system data 42 including the designated river and the hydroelectric power plant that discharges the river from the database 40 (step S3). ). Then, the predicted water level data creation means 50 extracts the operation plan data 41 of the hydroelectric power plant included in the grid data 42 (Step S4). Here, as the operation plan data 41, for example, data relating to the discharge amount, the discharge start time, the discharge stop time, and the like are extracted.

  Next, the predicted water level data creating means 50 extracts the reference water level data 43 at the designated place of the designated river from the database 40 (step S5), and based on the extracted reference water level data 43 and the operation plan data 41, Predicted water level data 2 is created (step S6). Thereafter, the predicted water level data providing means 70 provides (transmits) the created predicted water level data 2 to the user terminal 10 via the network 30 (step S7). On the other hand, the user's terminal 10 side receives the predicted water level data 2 transmitted from the river predicted water level data creation server 20 (step S8). Thereby, the user can predict the water level fluctuation of the river based on the input data 1 based on the received predicted water level data 2.

  As described above, in the river predicted water level data creation system according to the present embodiment, the predicted water level data 2 is created by the predicted water level data creating means 50, and the created predicted water level data 2 is provided to the user terminal 10. Since it did in this way, the user can predict the water level of the river which fluctuates by the water discharge start or the water discharge stop of the hydroelectric power plant based on the predicted water level data 2 in advance.

  As a result, for example, when fishing at a river, especially when fishing for carp, etc., a fishing ground can be determined based on the predicted water level data 2. That is, the predicted water level data 2 can be used as fishing ground predicted water level data. Here, in carp fishing, for example, even if the water level of a river (seed) rises about several tens of centimeters, and even if it rises about several centimeters depending on the location, it is impossible to catch carp, so it must be changed to a fishing place with an optimal water level. . However, by selecting the fishing ground based on the predicted water level data 2 for predicting the fluctuation of the water level due to the operation of the hydroelectric power plant, the fishing ground can be changed due to the fluctuation of the water level due to the operation status of the hydroelectric power plant. The labor associated with changing the fishing spot can be reduced. In addition, since the predicted water level can be grasped in advance, it is possible to appropriately adjust the fishing tackle, fishing method, etc. according to the predicted water level.
