Description

The present invention relates to an equipment monitoring device and an equipment monitoring method for monitoring the operation of equipment installed in facilities such as buildings and plants.

Conventionally, in relatively large-scale facilities such as buildings and plants, equipment monitoring devices for monitoring the operation of many equipment installed in the facilities have been used (for example, Patent Document 1).

JP-A-2002-133556

In the monitoring work, when some abnormality occurs in the equipment installed in the facility, the abnormality is detected by the equipment monitoring device. When the equipment monitoring device detects an abnormality in the equipment, it generates an alarm screen to notify the detection of the abnormality and displays it on a display unit such as a monitor to notify the administrator or the like who is the user of the detection of the abnormality. There is.

By the way, the equipment monitoring device may detect a plurality of abnormalities in the same equipment. When the equipment monitoring device detects a plurality of abnormalities in the same equipment, it generates an alarm screen notifying the detection of each abnormality and displays it on the display unit.

A display example of the alarm screen in this case is shown in FIG. For example, suppose that the equipment monitoring device detects an "upper limit abnormality" for a certain equipment, and then newly detects an "communication abnormality" for the same equipment as the equipment. The "upper limit abnormality" is an abnormality detected when the value measured by the equipment exceeds a preset upper limit value. "Communication abnormality" is an abnormality detected when communication is interrupted between the equipment and the equipment monitoring device.

In the conventional equipment monitoring device, first, an alarm screen 300 for notifying the detection of the upper limit value abnormality detected first is generated, and this screen is displayed on the display unit. On the alarm screen 300, "2019/06/13 21:27:44" is the date and time when the abnormality was detected, and "point" is a heading indicating the equipment (point) where the abnormality was detected, "MG.A. "I" indicates the identifier of the equipment that detected the abnormality, and "AI of BACnet" indicates the name of the equipment that detected the abnormality. Further, "Lv.4" indicates the importance set in advance by the administrator or the like for the abnormality of the upper limit value of the equipment, and "100 m2" indicates the measured value actually measured by the equipment. The illustrated example indicates that an abnormality in the upper limit value was detected because the measured value exceeded the upper limit value.

Next, the equipment monitoring device determines whether or not the preset importance of the newly detected communication abnormality is equal to or higher than the importance “Lv.4” of the previously detected upper limit value abnormality. If the importance set for the communication abnormality is equal to or higher than the upper limit abnormality importance "Lv.4", the equipment monitoring device generates an alarm screen notifying the detection of the communication abnormality, and the generated alarm screen is displayed. Update the display contents of the display unit.

For example, when the importance of the newly detected communication abnormality is "Lv.5", the importance of the communication abnormality is equal to or higher than the importance of the upper limit value abnormality "Lv.4". Therefore, the equipment monitoring device generates an alarm screen 400 for notifying the detection of a communication abnormality, and updates the display content of the display unit on the generated alarm screen 400. As a result, the alarm screen 400 is finally displayed on the display unit. "No response" on the alarm screen 400 indicates that a communication abnormality has been detected.

On the other hand, when the importance of the communication abnormality is lower than the importance of the upper limit abnormality "Lv.4", the equipment monitoring device does not generate and display the alarm screen 400 notifying the detection of the communication abnormality, and the upper limit value abnormality occurs. The display of the alarm screen 300 notifying the detection is continued.

In this way, in the conventional equipment monitoring device, when a plurality of abnormalities are detected for the same equipment, only the alarm screen for notifying the most important abnormality is based on the importance set for each detected abnormality. Was configured to be displayed on the display unit. Therefore, it is difficult for the conventional equipment monitoring device to grasp the situation where a plurality of abnormalities are detected for the same equipment.

The present invention has been made to solve the above problems, and an object of the present invention is to provide an equipment monitoring device capable of presenting a situation in which a plurality of abnormalities have been detected for the same equipment.

It may be provided outside the equipment monitoring device 1 instead of the configuration of. When the importance acquisition unit 15 is not provided in the equipment monitoring device 1, the screen generation unit 13 may generate at least a first alarm screen displaying the content of the abnormality detected by the abnormality detection unit 12. When a plurality of abnormalities are detected in the same equipment by the abnormality detection unit 12, at least a second alarm screen listing the contents of the plurality of abnormalities may be generated.

Next, the flow of processing by the equipment monitoring device 1 will be described with reference to the flowchart of FIG.

First, the data collection unit 11 collects data on the operating status of each equipment from each equipment 2 via the communication line 3 (step ST1). The data collection unit 11 may store the collected data on the operating status in a database (not shown).

The abnormality detection unit 12 determines whether or not an abnormality has been detected in any of the equipment based on the data on the operating status of each equipment collected by the data collection unit 11 (step ST2). Since the method of detecting an abnormality by the abnormality detecting unit 12 is the same as that of the conventional method, detailed description thereof will be omitted.

If no abnormality is detected in any of the equipment by the abnormality detection unit 12 in step ST2 (step ST2; NO), the equipment monitoring device 1 ends the process. After that, the equipment monitoring device 1 may start the process again from step ST1.

When an abnormality is detected in any of the equipment by the abnormality detection unit 12 in step ST2 (step ST2; YES), the importance acquisition unit 15 refers to the equipment information storage unit 18 and detects the detected abnormality. Acquire the preset importance (step ST3).

Next, the abnormality detection unit 12 determines whether or not a plurality of abnormalities have been detected for the same equipment as a result of detecting the abnormality in step ST2 (step ST4). When a plurality of abnormalities have not been detected for the same equipment (step ST4; NO), the screen generation unit 13 has the content of the abnormality detected by the abnormality detection unit 12 in step ST2 and the importance acquisition unit in step ST3. A first alarm screen displaying the importance of the abnormality acquired in step 15 is generated (step ST5).

The display control unit 14 causes the display unit 19 to display the first alarm screen generated by the screen generation unit 13 (step ST6), and ends the process. After that, the equipment monitoring device 1 may start the process again from step ST1.

On the other hand, when a plurality of abnormalities are detected for the same equipment as a result of detecting an abnormality in step ST2 (step ST4; YES), the importance changing unit 17 is acquired by the importance acquisition unit 15 for the equipment. The highest importance of the plurality of abnormalities is changed to a higher importance than the highest importance (step ST7).

The screen generation unit 13 generates a second alarm screen that lists the contents of a plurality of abnormalities detected for the same equipment and displays the importance and the like changed by the importance change unit 17 in step ST7. (Step ST8).

The display control unit 14 causes the display unit 19 to display a second alarm screen generated by the screen generation unit 13 instead of the first alarm screen already displayed on the display unit 19 for the equipment. , The display content of the display unit 19 for the equipment is updated on the second alarm screen (step ST9), and the process is terminated. After that, the equipment monitoring device 1 may start the process again from step ST1.

Next, an operation example of the equipment monitoring device 1 will be described with reference to specific examples. FIG. 3 is a diagram showing an example of the importance of the abnormality stored in the equipment information storage unit 18.

In addition, the administrator or the like may appropriately change the importance of the abnormality according to the operation status after the operation of the equipment monitoring device 1 is started.

FIG. 4 shows a display example of an alarm screen when a plurality of abnormalities are detected in the same equipment in the equipment monitoring device 1. Here, it is assumed that an upper limit abnormality is detected for the equipment with the identifier "MGAI", and then a communication abnormality is detected for the same equipment as the equipment.

When the abnormality detection unit 12 detects an upper limit abnormality, the importance acquisition unit 15 refers to the equipment information storage unit 18, and the importance of the upper limit abnormality in the equipment with the identifier "MGAI". Acquire "Lv.4" (see FIG. 3). The screen generation unit 13 displays the importance “Lv.4” acquired by the importance acquisition unit 15 and the content of the abnormality (displayed as “upper limit value” in FIG. 4) on the first alarm screen 100. Generate. The display control unit 14 causes the display unit 19 to display the first alarm screen 100.

After that, when a communication abnormality is detected for the same equipment as the equipment in which the upper limit abnormality is detected, the importance acquisition unit 15 refers to the equipment information storage unit 18 and is assigned the identifier "MGAI". Acquire the importance "Lv.5" of communication abnormality in the equipment (see FIG. 3). The importance changing unit 17 sets the higher importance "Lv.5" of the upper limit abnormality importance "Lv.4" and the communication abnormality importance "Lv.5" from the highest importance. Also high, for example, change to "Lv.7".

The screen generation unit 13 lists the contents of the plurality of detected abnormalities as, for example, "no response / upper limit value", and displays the importance level "Lv.7" changed by the importance level changing unit 17. The second alarm screen 200 is generated. The display control unit 14 displays the equipment by displaying a second alarm screen on the display unit 19 instead of the first alarm screen 100 already displayed on the display unit 19. The display content of unit 19 is updated on the second alarm screen.

In this way, when a plurality of abnormalities are detected in the same equipment in the equipment monitoring device 1, the display contents of the display unit 19 are updated on the second alarm screen 200 in which the contents of the detected plurality of abnormalities are listed.
