<Operation of Plant Monitoring Information Display System According to One Embodiment>
Next, the operation of the plant monitoring information display system 1 according to this embodiment will be described.

  In the plant controller 30 in the plant X, the process data of the device 20 (power ON / OFF state, failure state, circuit breaker and disconnector open / close state information, voltmeter, etc.) at a predetermined time interval from the device 20 (MCCB-a). An ammeter measurement value) is acquired and transmitted to the monitoring control device 40. Processing executed by the monitoring control device 40 when such information is acquired will be described with reference to the flowchart of FIG.

  In the monitoring control device 40, the current process data of the device 20 transmitted from the plant controller 30 is acquired by the process data current value acquisition unit 42 and stored in the process data current value database 43 (S1).

  Next, in the event occurrence information generation unit 44, an event occurrence condition corresponding to the identification information and attribute information of the process data acquired in step S1 is acquired from the condition database 41 (S2). For example, regarding the attribute information “approaching attention” of the device 20, the event occurrence condition “when the power is on” is acquired.

  Next, in the event occurrence information generation unit 44, among the process data stored in the process data current value database 43, the event corresponding to the event occurrence condition stored in the condition database 41 is generated in the equipment apparatus. Event occurrence information indicating that the event has occurred is generated and stored in the event occurrence information database 45 (S3). For example, when the process data value stored in the process data current value database 43 corresponds to the event occurrence condition “when the power is on” acquired from the condition database 41, the process data value is based on the attribute information corresponding to the process data. Event occurrence information indicating that it is dangerous to approach the device 20 is generated and stored.

  Thus, in the state where the event occurrence information is generated and stored at any time in the monitoring control device 40, a worker who performs maintenance work in the plant X captures the plant X while photographing the inside of the plant X with the camera device 61 of the portable terminal 60. A process executed by the portable terminal 60 when moving in X will be described with reference to the flowchart of FIG.

  When the worker moves while photographing the inside of the plant X with the camera device 61 of the portable terminal 60, the camera device 61 determines whether the barcode of the cable position information label 11 or the device position information label 21 is detected as a subject. Monitored (S11). Here, it is assumed that the cable 10 and the device 20 connected thereto are photographed, and the barcodes of the cable position information label 11 and the device position information label 21 are detected as subjects.

  When the barcode of the cable position information label 11 or the device position information label 21 is detected as a subject in the camera device 61 (“YES” in S11), the video information generation unit 64 determines from the detected video information of the barcode. The position in the plant X of the cable 10 and the apparatus 20 is specified. Then, event occurrence information regarding the cable 10 and the device 20 corresponding to these positions is acquired from the event occurrence information database 45 of the monitoring control device 40 (S12).

  Here, it is assumed that the power of the device 20 is in an ON state, and thereby event occurrence information “access to the device 20 and the connected cable 10 is dangerous” is acquired.

  Next, in the video information generation unit 64, shape information regarding the device 20 and the cable 10 from which the event occurrence information has been acquired is acquired from the shape database 63 (S13).

  Further, the video information generation unit 64 uses the shape information acquired from the shape database 63 and the shooting direction information of the camera device 61 as the video information of the cable 10 and the device 20 in the plant X taken by the camera device 61. Then, video information based on augmented reality technology in which drawing information for emphasizing the corresponding device 20 and the peripheral portion of the cable 10 as an approaching attention area is superimposed and displayed on the display unit 65 (S14).

  An example of the portable terminal 60 when the generated video information is displayed on the display unit 65 is shown in FIG. In FIG. 6, since the event occurrence information is transmitted to the video information of the cable 10 and the device 20 in the plant X captured by the camera device 61 on the display unit 65 of the mobile terminal 60, the area A, In addition, the drawing information in which the area B is emphasized as the approaching attention area is displayed in a superimposed manner.

For example, the area to be noted may be displayed in red, and the safe area may be displayed in green.

  An operator who moves in the plant X is displayed on the portable terminal 60 by displaying on the portable terminal 60 the image information in which the area that should be careful of approaching and touching is displayed on the portable terminal 60. It is possible to intuitively grasp a point to be noted without sequentially checking the state of each device (power supply state, meter measurement value, etc.).

  Further, after the display is performed in this manner, when the event occurrence state is canceled and the event occurrence information is not acquired because maintenance work is performed on the corresponding device by the worker, for example, the power source of the device 20 is Is turned off and is in a normal state, the process data after maintenance work is acquired from the device 20, and the superimposition of the drawing information emphasized as an area to be noted is released, indicating that the area is a safe area. It is switched to the video information shown. By switching in this way, the worker can confirm that the device 20 has been reliably switched to a desired state by the work performed by himself / herself.

  In the present embodiment, as the event occurrence information, a case has been described in which the periphery of the device 20 and the cable 10 is displayed as an approach caution area when the power of the device 20 is ON. For example, measurement of the device in the plant When it is detected that the value is greater than or equal to a preset threshold and contact with the device is dangerous, or when it is in a failure state and it is necessary to have the worker perform repair work, the screen of the mobile terminal The corresponding device part on the top may be highlighted and displayed. In addition, a condition based on a plurality of data states of the devices in the plant, for example, when “power is on” and “process data value is greater than or equal to threshold x” (and condition), or “process data value is threshold When it is “more than x” or “the process data value is less than or equal to the threshold value y” (or condition), the event generation condition may be set. The threshold may be a relative change amount in a predetermined time.

  Further, in the present embodiment, the case where the position in the plant X is specified using the barcode with the position information label has been described, but a tag using RFID (Radio Frequency Identification) is attached to the position information label. The position may be identified using this. In this case, the portable terminal 60 is equipped with an RFID reading function, thereby receiving position information from the RFID tag and specifying the position of the equipment device.

  Further, in the highlighted display area in the video information displayed on the display unit 65 of the mobile terminal 60, not only the display by color, but also a mark (for example, “!” Mark) for calling attention set in advance. Object information may be superimposed and displayed.

  In addition, by setting radio waves to be transmitted from a device in a dangerous state and installing a function for receiving the radio waves in the mobile terminal 60, work is performed in a place that is dangerous and requires attention. When it is determined that an operator is approaching, an alarm sound may be generated from the mobile terminal or the mobile terminal may be vibrated, so that the worker can be more surely notified of the danger.

  In the present embodiment, the case where the condition database 41 and the event occurrence information database 45 in the monitoring control device 40 are in the monitoring control device 40 has been described. However, these are stored in an external storage device connected to the monitoring control device 40. May be stored, and necessary information may be acquired and used by the monitoring control device 40 each time.

  Further, in the present embodiment, the case has been described in which the monitoring control device acquires process data and generates event occurrence information. However, these functions may be mounted on a mobile terminal and executed on the mobile terminal.

  In this embodiment, the case where the camera device and the display device are mounted on the portable terminal carried by the worker has been described. However, these devices are mounted on the head mounted display, and the worker should be careful not to use the hand. It is also possible to make it possible to visually recognize an image in which a power point is emphasized and improve the efficiency of maintenance work.
