  FIG. 3 is a schematic block diagram showing the functional configuration of the image recognition device 18 in the first embodiment. The image recognition device 18 includes a CPU (Central Processing Unit), a memory, an auxiliary storage device, and the like connected by a bus, and executes an image recognition program. The image recognition device 18 functions as a device including an image acquisition unit 181, an image data storage unit 182, an image recognition unit 183, and an output unit 184 by executing an image recognition program. Note that all or part of each function of the image recognition device 18 may be realized using hardware such as an application specific integrated circuit (ASIC), a programmable logic device (PLD), or a field programmable gate array (FPGA). . The image recognition program may be recorded on a computer-readable recording medium. The computer-readable recording medium is, for example, a portable medium such as a flexible disk, a magneto-optical disk, a ROM, a CD-ROM, or a storage device such as a hard disk built in the computer system. The image recognition program may be transmitted via a telecommunication line.

The image acquisition unit 181 is a functional unit that acquires image data output from the camera 17.
The image data storage unit 182 is a functional unit that stores the image data acquired by the image acquisition unit 181. The image data storage unit 182 is configured using a storage device such as a magnetic hard disk device, a semiconductor storage device, or an SD card.
The image recognition unit 183 performs image processing and character recognition processing on the image data stored in the image data storage unit 182, so that the operation panel 132 and display of the machine-side operation panel 13 captured in the image data are displayed. It is a functional unit that acquires recognition result information by recognizing information on characters and numerical values shown on the board 133.
The output unit 184 is a functional unit that outputs the recognition result information obtained by the image recognition unit 183 to the connection destination.

FIG. 4 is a sequence diagram illustrating the flow of processing during the update period of the dam management system 100 according to the first embodiment. Assume that the existing system is connected to the machine-side operation panel 13 at the start of the processing of FIG.
In the update period of the dam management system 100, a new installation system is temporarily installed (step S101). Specifically, an administrator or the like first installs the new machine-side transmission device 14 in the gate room, and installs the new input / output device 15 and the new discharge operation device 16 in the dam management office. Then, an administrator or the like connects the new machine side transmission device 14 and the new input / output device 15 by FL-net, and connects the new input / output device 15 and the new discharge operation device 16.

  When the temporary installation of the new system is completed, a new / old system switching process is performed (step S102). The old / old system switching process is a process for replacing the existing system with the new system. The new / old system switching process is performed by an administrator or the like. Specifically, the administrator or the like first stops the existing system and releases the connection between the machine-side operation panel 13 and the existing system. Next, the administrator or the like connects the newly installed system to the machine-side operation panel 13 instead of the existing system. As a result, the new system is connected to the rear stage of the machine-side operation panel 13, that is, the output destination of monitoring data and measurement data.

  Then, the administrator or the like installs the camera 17 at a position where the photographing target area 131 of the machine-side operation panel 13 can be photographed, and connects the image recognition device 18 as an output destination of image data obtained by the camera 17. Further, the administrator or the like connects the existing system as an output destination of the recognition result by the image recognition device 18. In this way, the administrator or the like prepares an environment where the dam can be monitored in the existing system.

  The machine-side operation panel 13 acquires various data such as measurement data obtained from measurement equipment provided in the dam sluice facility and monitoring data (step S103). The machine-side operation panel 13 displays the acquired various data on the display panel 133 (step S104). The camera 17 captures an image capturing area on the machine-side operation panel 13 (step S105). For example, the camera 17 shoots a shooting target area on the machine-side operation panel 13 with a moving image. In this case, the camera 17 outputs all image data obtained by photographing to the image recognition device 18 (step S106).

  The image acquisition unit 181 acquires image data output from the camera 17. The image acquisition unit 181 stores the acquired image data in the image data storage unit 182. When acquiring image data in time series, the image acquisition unit 181 stores the image data in the image data storage unit 182 in time series. Thereafter, the image recognition unit 183 performs image recognition using the image data stored in the image data storage unit 182 (step S107).

  Specifically, first, the image recognition unit 183 acquires one piece of image data stored in the image data storage unit 182. Next, processing such as image processing and character recognition processing is performed on the acquired image data. The image recognizing unit 183 may use any technique as long as it can read characters and numerical values of the operation panel 132 and the display panel 133 captured in the image data. The image recognition unit 183 outputs the result obtained by the image recognition as recognition result information to the existing machine side transmission device 19 in the existing system (step S108). The existing machine side transmission device 19 transmits the recognition result information output from the image recognition device 18 to the existing input / output device 20 via the existing machine side transmission device 19. The existing input / output device 20 displays the recognition result information transmitted from the existing machine side transmission device 19 (step S109).

Whether the administrator or the like can monitor the dam in the existing system by checking whether the recognition result information is displayed on the existing input / output device 20 or by viewing the recognition result information displayed on the existing input / output device 20. Determine whether or not. At this time, if the administrator or the like determines that the existing system cannot monitor the dam, the administrator or the like prepares an environment in which the existing system can monitor the dam again.
On the other hand, when the administrator or the like determines that the dam can be monitored with the existing system, an environment for monitoring the dam with the existing system is established.

  When the environment for monitoring the dam is established in the existing system, the manager or the like starts an operation test of the new system (step S110). In the operation test of the new system, the administrator turns on the power to the new system and confirms whether the new system operates normally. When the new system is turned on, the machine-side operation panel 13 outputs the acquired various data to the new machine-side transmission device 14 in the new system (step S111). The new machine side transmission device 14 transmits the various output data to the new discharge operation device 16 via the new input / output device 15. The new release operation device 16 displays various data transmitted from the new machine side transmission device 14 (step S112). Communication between the machine-side operation panel 13 and the new machine-side transmission device 14, communication between the new machine-side transmission device 14 and the new input / output device 15, and between the new input / output device 15 and the new discharge operation device 16 It is possible to determine that the new system is operating normally by performing the communication without disconnection. If it can be determined that the new system operates normally, the administrator or the like removes the camera 17, the image recognition device 18, and the existing system (step S113).

  According to the dam management system 100 configured as described above, measurement and monitoring can be performed even during the renewal work period. Specifically, in the dam management system 100, the display portion of the measurement data and monitoring data of the machine-side operation panel 13 is photographed by the camera 17 during the renewal work period, and the image data obtained by the image recognition device 18 by the camera 17 is captured. Use the image recognition technology to read the measurement / monitoring data and import the read data into the existing system. This eliminates the need for investigating the interface between the measuring instrument to the machine-side operation panel and input / output devices for signal branching, and to produce a signal branching board for each measuring instrument. Can be operated in parallel. Therefore, measurement and monitoring can be performed even during the renewal construction period.

<Modification in First Embodiment>

With this configuration, the dam can be monitored by image data.
The image recognition device 18 may be configured to output the recognition result information to the existing system only when there is a change in the monitoring data and the measurement data in consideration of the transmission capacity. When configured in this way, the image recognition device 18 obtains the value of measurement data or the value of monitoring data obtained by the image recognition technique for the image data obtained at time (t-1) and the time t. The measurement data value or the monitoring data value obtained by the image recognition technique for the obtained image data is compared, and if they do not match, the recognition result information is output to the existing system. The image recognition device 18 recognizes the value of the measurement data or the monitoring data obtained by the image recognition technique for the image data obtained at time (t-1) and the image recognition for the image data obtained at time t. The value of the measurement data or the value of the monitoring data obtained by the technique is compared, and if they match, the recognition result information is not output to the existing system.
With this configuration, it is not necessary to output recognition result information to the existing system every time image data is obtained. Therefore, the transmission capacity can be suppressed.

FIG. 7 is a sequence diagram illustrating a processing flow of the dam management system 100a according to the second embodiment. The processing similar to that in FIG. 4 is denoted by the same reference numerals as those in FIG.
When the temporary installation of the new system is completed in the process of step S101, a new / old system switching process is performed (step S201). In the new / old system switching process in the second embodiment, the administrator or the like connects the image data output unit 30 to the camera 17 as an output destination of the image data obtained by the camera 17, and outputs from the image data output unit 30.

  The image acquisition unit 301 stores the acquired image data in the image data storage unit 302. When the image acquisition unit 301 acquires image data in time series, the image data storage unit 302 stores the image data in time series. Thereafter, the communication unit 303 transmits the image data stored in the image data storage unit 302 to the cloud server 22 (step S202). The communication unit 303 may transmit a plurality of pieces of image data stored in the image data storage unit 302 to the cloud server 22 or may transmit the image data to the cloud server 22 one by one.
