FIG. 1 is a schematic configuration diagram showing a waterway monitoring device 100 according to Embodiment 1 of the present invention, and devices and equipment connected to the waterway monitoring device 100.
FIG. 2 is a schematic diagram 40 of an irrigation channel Y according to Embodiment 1 of the present invention.
FIG. 3 is a diagram showing water information and specific water information obtained by the waterway monitoring apparatus 100 according to Embodiment 1 of the present invention.
The waterway monitoring device 100 according to the present embodiment is provided in a management center that monitors a waterway system composed of a plurality of waterways Y, measures a water level, a flow rate, and the like of the waterway Y, and relates to the waterway Y. It controls the opening and closing of equipment (gutters, valves) and the like to adjust the water level.

  In each part of the irrigation channel Y, there are provided measuring instruments 1A, 1B and 1C such as a water level meter and a flow meter for measuring water information J1 such as a water level and a flow rate of the water flowing through the irrigation channel Y. The water information J1 measured by these surveying instruments 1A, 1B, 1C is transmitted to the waterway monitoring device 100 via a telemeter, a telecon slave unit (hereinafter, referred to as a TM slave unit) 21, 22, 23, 24, 25. Is done.

A water system schematic diagram 40 as the schematic diagram information shown in FIG. 2 shows a connection relationship and a disposition relationship in which each water channel Y branches and joins in a water channel system constituted by a plurality of water channels Y. A portion indicated by a straight line in the drawing is an irrigation channel Y, and four irrigation channels Y are connected to the river shown on the right side in the drawing.
Further, the arrangement positions of the surveying instruments 1A, 1B, and 1C are indicated by triangular marks, and the water information J1 of the irrigation canal Y is acquired at these arrangement positions. The positions of the gutter gates 10A, 10B, and 10C as facilities are indicated by rectangles.

  Further, the water system schematic diagram 40 has a structural relationship K indicating the width, depth, and gradient of the irrigation channel Y. Although the structural relationships K of all the waterways Y are not shown in FIG. 2, the respective structural relationships K are registered in the respective waterways Y. The structural relationship K is registered, for example, by assigning an identification number for each irrigation canal Y and creating a database of the structural relationship K for each identification number.

The waterway monitoring device 100 obtains the water information J1 transmitted from each of the TM slave units 21, 22, 23, 24, and 25, and outputs a control signal P to the gutters 10A, 10B, and 10C as a telemeter as an input / output unit. And a control unit that accumulates the obtained water information J1 and generates a control signal P for controlling the gutters 10A, 10B, and 10C. A server 50, a monitor 54 for displaying information output from the server 50, and a WEB server unit 52 for distributing information output from the server 50 to the outside via the network 20 are integrally provided.
The server 50 has the water system schematic diagram 40 shown in FIG.

Hereinafter, a method of monitoring a waterway using the waterway monitoring apparatus 100 configured as described above will be described.
The water information J1 of the irrigation canal Y measured by each of the surveying instruments 1A, 1B, and 1C is accumulated in the server 50 of the irrigation canal monitoring device 100 as needed. Then, based on the water information J1 stored in the server 50 and the information on the connection relation and the arrangement relation of the irrigation canal Y shown in the water system schematic diagram 40, the server 50, for example, as specific locations T1 and T2 in the water system schematic diagram 40 The specific water information J2 indicating the water level, the flow rate, etc. at the indicated location is calculated.

For example, it is assumed that heavy rain has fallen and the river shown in FIG. Then, as shown in FIG. 3, it is assumed that the water level of the water information J1 at the installation location of the surveying instrument 1A is 3 m, the water level of the surveying instrument 1B is 1.6 m, and the water level of the surveying instrument 1C is 3.5 m. In this case, the server 50 sets the specific water information J2 (water level) at the specific location T1 to 1.8 m and the specific water information J2 (water level) at the specific location T2 to 2 based on the water information J1 and the water schematic diagram 40. .5m.
Further, the server 50 graphs or lists the acquired water information J1 and the calculated specific water information J2 and displays them on the monitor 54 together with the water system schematic diagram 40.

  Next, the server 50 determines whether or not the specific water information J2 (water level) at each of the specific locations T1 and T2 has reached a warning water level at which overflow occurs. In this case, for example, it is determined that the specific water information J2 (water level) at the specific location T1 has no problem, but the specific water information J2 (water level) at the specific location T2 has reached the alert level.

  Next, the server 50 selects a gutter that affects the water level of the specific location T2 as a control target, and displays the selected gutter on the monitor 54. Here, it is assumed that it is determined that two of the gutter gates 10B and 10C affect the water level at the specific location T2. Then, the server 50 automatically generates a control signal P for controlling the gutter gates 10B and 10C to close the gutter gates 10B and 10C. The generated control signal P is transmitted to the gutters 10B and 10C via the TM master station 51 and the TM slave stations 24 and 25. In this way, the gutter gates 10B and 10C are automatically and collectively closed, and backflow from the increased river is prevented, so that overflow at the specific location T2 is prevented.

  In addition, the server 50, in addition to the already displayed water information J1 and specific water information J2, information on the specific location T2 determined to have a possibility of flooding, information on the gutter gates 10B and 10C that performed the control, and the like. It is displayed on the monitor 54. At the same time, the server 50 publishes the information displayed on the monitor 54 to the Internet via the WEB server unit 52, and transmits the information to the external smartphone 7, the personal computer 6, and the like designated in advance as danger detection information. Thereby, the staff outside the management center can grasp the state of the water channel Y and the open / closed state of the gutter gates 10A, 10B, 10C.

  According to the irrigation canal monitoring device 100 of the present embodiment configured as described above, the server 50 has the water information J1 such as water level and flow rate measured by each of the surveying instruments 1A to 1C, and the water system schematic diagram 40 of the irrigation canal Y. Based on the above, it is possible to calculate specific water information J2 such as a water level and a flow rate at a specific location where no surveying instrument is provided. Then, the server 50 automatically controls the gutter related to the specific location determined to have overflow. In this way, flooding of the irrigation canal Y can be prevented, thereby preventing damage from inundation.

The waterway monitoring device 100 is configured by integrating a server 50, a TM master station unit 51, and a WEB server unit 52. Therefore, one of the waterway monitoring devices 100 can collect water information J1, calculate specific water information J2, control the gutters 10A to 10C, display on the monitor 54, and disclose information to the Internet. As a result, the number of devices can be reduced, and space and power can be saved.
Moreover, since the water system schematic diagram 40 has the structural relationship K indicating the width, the depth, and the gradient of the irrigation channel Y, the calculation accuracy of the specific water information J2 by the server 50 can be improved.

  The data transmission of the water information J1 and the control signal P between the respective TM slave units 21, 22, 23, 24 and 25 and the TM master unit 51 includes a wireless LAN line, an MCA wireless line, Lines according to local characteristics, such as a power wireless line, a mobile phone line, an optical cable line, and a metal IP line, are used.

In the above description, the opening and closing control of the gutter gates 10A to 10C provided in the irrigation canal Y has been described. However, the present invention is not limited to the control of the gutter gates. It may control equipment such as a floodgate installed in a secondary river or a tsunami floodgate along the coast.
In the above description, the specific locations T1 and T2 are described as an example where the surveying instruments 1A to 1C are not provided. However, the locations where the surveying instruments 1A to 1C are provided may be used as the specific locations. In this case, it is possible to confirm whether there is an error between the actually measured water information J1 and the calculated specific water information J2.

Embodiment 2 FIG.
Hereinafter, a second embodiment of the present invention will be described with reference to the drawings, focusing on points different from the first embodiment. The same parts as those in the first embodiment are denoted by the same reference numerals, and description thereof will be omitted.
FIG. 4 is a schematic configuration diagram showing the waterway monitoring device 200 according to the first embodiment of the present invention and devices connected to the waterway monitoring device 200.
The waterway monitoring device 200 of the present embodiment includes a console 253 operated by the operator 5.
In the first embodiment, the server 50 generates the control signal P for closing the gutter that affects the water level at the specific location based on the specific water information J2. In the present embodiment, when generating the control signal P, an operation signal S externally input by the operator 5 from the console 253 is used in addition to the specific water information J2.

  Hereinafter, a method for monitoring a waterway using the waterway monitoring device 200 configured as described above will be described. As in the first embodiment, the server 50 selects a gutter to be controlled based on the water information J1 acquired by the surveying instruments 1A to 1C and the calculated specific water information J2, and displays the gutter on the monitor 54. Here, it is assumed that the water level at the specific location T1 has reached the alert level, and only the gutter 10C is selected as a control target and is displayed on the monitor 54.

  The operator 5 determines, based on his or her own rule of thumb, whether the gutter to be controlled can be controlled only by the gutter 10C. For example, when the operator 5 determines that it is necessary to perform control to close the gutter 10B together with the gutter 10C, the operator 5 inputs an operation signal S for closing the gutter 10B via the console 253.

  Thus, the server 50 generates the control signal P for controlling the gutter gate 10B specified by the operation signal S in addition to the gutter gate 10C automatically selected based on the specific water information J2. Thus, both the gutter gates 10B and 10C are closed, and the overflow at the specific location T1 is prevented.

According to the irrigation canal monitoring device 200 of the present embodiment configured as described above, the same effect as in the first embodiment is achieved, and the specific water information J2 such as the water level and the flow rate at the specific location where the surveying instrument is not provided is provided. Can be calculated and the gutter gate associated with the specific location can be controlled. In this way, flooding of the irrigation canal Y can be prevented, thereby preventing damage from inundation.
Furthermore, since the gutter to be controlled can be selected and adjusted based on the empirical rules of the operator 5, the gutter can be controlled based on comprehensive and multifaceted judgment. As a result, the effect of preventing overflow of the water channel Y is further improved.

  The specific location for calculating the specific water information J2 may be specified by the operator 5 via the console 253.

Embodiment 3 FIG.
Hereinafter, a third embodiment of the present invention will be described with reference to the drawings, focusing on points different from the first embodiment. The same parts as those in the first embodiment are denoted by the same reference numerals, and description thereof will be omitted.
FIG. 5 is a schematic configuration diagram showing the waterway monitoring device 300 according to the first embodiment of the present invention and devices connected to the waterway monitoring device 300.
In the irrigation canal monitoring device 300 of the present embodiment, the TM master unit 351 acquires environmental information J3 in addition to acquiring water information J1 transmitted from each of the surveying instruments 1A to 1C.

The environmental information J3 includes weather information, earthquake information, tsunami information, tide level information, dam water discharge information, and the like, which indicate the surrounding state of the irrigation canal Y.
Then, the server 50 uses the environmental information J3 in addition to the water information J1 and the water schematic diagram 40 in the calculation of the specific water information J2.
For example, if weather information (heavy rain warning, rainfall amount 40 mm per hour) is acquired as environmental information J3, in addition to water information J1 and water system schematic diagram 40, specific water information J2 is obtained using this heavy rain warning (environmental information J3). Is calculated. This enables more accurate calculation of the specific water information J2.

Further, the waterway monitoring device 300 may perform the following control.
The server 50 calculates the specific water information J2 by using the environmental information J3 up to a predetermined date and time from the environmental information J3 acquired by the TM master station unit 351 in addition to the water information J1 and the water system schematic diagram 40. . For example, when the predetermined date and time is 7 hours later, the environmental information J3 up to 7 hours later is a heavy rain warning, and the rainfall is 30 mm from now to 3 hours later, and 40 mm per hour from 3 hours to 7 hours later. This information is added to predict and calculate the specific water information J2 up to 7 hours later. This makes it possible to predict the specific water information J2 up to a predetermined date and time.

Further, the waterway monitoring device 300 may perform the following control.
The server 50 may determine the specific location for calculating the specific water information J2 based on the acquired environment information J3.

For example, when the water discharge information of the dam (upstream of the river Q, 500 cubic meters per second) is acquired as the environmental information J3, only the part related to the water discharge of the dam of the river Q is determined as the specific point T3 and is determined. The calculation of the specific water information J2 is performed only at the specific location T3.
By performing such control, the control load when calculating the specific water information J2 can be reduced, and the calculation speed of the specific water information J2 can be increased.

  According to the irrigation canal monitoring device 300 of the present embodiment configured as described above, the same effect as in the first embodiment is achieved, and the specific water information J2 such as the water level and the flow rate at the specific location where the surveying instrument is not provided is provided. Can be calculated and the gutter gate associated with the specific location can be controlled. In this way, flooding of the irrigation canal Y can be prevented, thereby preventing damage from inundation.

Further, since the environmental information J3 such as weather information is used in the calculation of the specific water information J2, the calculation accuracy of the specific water information J2 can be improved. As a result, the effect of preventing overflow of the water channel Y is further improved.
In addition, since the specific water information J2 can be predicted up to a predetermined date and time, a schedule or the like of an operator can be planned in advance.
Further, based on the environment information J3, a specific location that requires the specific water information J2 is determined, and the specific water information J2 is calculated only for the determined specific location, so that the control speed of the server 50 can be increased.

  In addition, when calculating the specific water information J2 by adding the environmental information J3, a plurality of environmental information J3, for example, tsunami information (earthquake intensity, tsunami height) and tide level information may be combined.

  In the present invention, each embodiment can be freely combined, or each embodiment can be appropriately modified or omitted within the scope of the invention.
