The state information associated with the time information is reproduced at a higher speed than in the case of reproducing the state information.

The extraction unit 450 extracts the time information based on, for example, the rate of change of the value indicating the state information P1. For example, the extraction unit 450 extracts time information when the rate of change of the value indicating the state information P1 is relatively high. In FIG. 6, the reproduction time (time zone) for reproducing the time information having a relatively high change rate is “00:00:10 to 00:00:13” and “00:00:36 to 00: 00:39". When reproducing these time zones, the reproducing unit 470 reproduces the status information P1 on the process flow screen 4 at a relatively high speed (for example, a reproduction speed exceeding 1× speed). The reproducing unit 470 may skip the reproduction of the state information P1 in these time zones and reproduce the state information P1 in other time zones.

When reproducing the state information P1 in these time zones, the reproducing unit 470 reproduces the state information P1 on the process flow screen 4 at a relatively low speed (for example, a reproduction speed of 1× speed).

FIG. 7 is a diagram showing a second example of the reproduction speed in the first embodiment. In FIG. 7, the horizontal axis represents the reproduction time. The vertical axis represents state information. The extraction unit 450 extracts the time information based on, for example, the rate of change of the value indicating the state information P1 or the state information P2. The extraction unit 450 also extracts time information indicating the time when the value indicating the state information P1 is equal to or greater than or equal to the state information P2, based on the arithmetic expression input to the arithmetic expression input area 31. For example, the extraction unit 450 extracts time information when the state information P1 (process value) becomes equal to or larger than the state information P2 (other process value). In FIG. 7, the reproduction time (time zone) for reproducing the time information when the state information P1 is equal to or more than the state information P2 is “00:00:20 to 00:00:23” and “00:00: 28 to 00:00:31". When reproducing the state information P1 and the state information P2 in these time zones, the reproducing unit 470 displays the state information P1 and the state information P2 on the process flow screen 4 at a relatively low speed (for example, a reproduction speed of 1× speed). Reproduce.

As described above, the monitoring system 1 according to the first embodiment has the process information acquisition unit 440, the extraction unit 450, and the reproduction unit 470. The process information acquisition unit 440 acquires the process information in which the status information indicating the status of the monitoring targets 10-1 to 10-N and the time information indicating the time when the status is reached are associated with each other. The extraction unit 450 extracts, from the process information, time information indicating the time at which a predetermined event (for example, an event whose state information is equal to or more than a threshold value) occurs in the state of the monitoring targets 10-1 to 10-N. When reproducing the state information in time series, the reproducing unit 470 reproduces the state information associated with the extracted time information when reproducing the state information associated with the unextracted time information. Play at a faster speed than you would.

The monitoring method in the monitoring system 1 of the first embodiment includes a step of acquiring process information, a step of extracting from the process information, and a step of reproducing at a high speed. The step of acquiring the process information is a step of acquiring the process information in which the status information indicating the status of the monitoring targets 10-1 to 10-N and the time information indicating the time when the status is reached are associated with each other. The step of extracting from the process information is a step of extracting, from the process information, time information indicating the time when a predetermined event occurs in the state of the monitoring targets 10-1 to 10-N. When reproducing the state information in time series, the step of reproducing at a high speed includes reproducing the state information associated with the unextracted time information, and the state information associated with the extracted time information. This is a step of reproducing at a higher speed than the case of reproducing.

With this configuration, when reproducing the state information in time series, the reproducing unit 470 reproduces the state information associated with the unextracted time information, when reproducing the state information associated with the unextracted time information. Playback is performed at a faster speed than when information is played back. That is, the reproduction unit 470 reproduces the state information at the reproduction speed depending on whether or not it is the extracted time information. For example, the reproducing unit 470 increases the reproduction speed when reproducing the state information associated with the time information that has not been extracted.
As a result, the monitoring system 1 and the monitoring method of the first embodiment can efficiently reproduce the state information indicating the state of the monitoring target in an arbitrary past period in time series.

The monitoring system that does not have the reproduction unit 470 advances the reproduction time for reproducing the state information at fixed intervals (eg, 1 minute) from the past to the present in the period designated by the user at a constant cycle. Was there. That is, the monitoring system that does not have the reproduction unit 470 reproduces the state information in time series at the same reproduction speed from the beginning to the end on the process flow screen. For this reason, the monitoring system that does not have the regeneration unit 470 confirms an event in which certain specific state information (for example, the flow rate of the pump) has changed significantly, or an event in which the certain state information has a specific value such as an upper limit value. If it wants to do so, it must continue to play until the event occurs, and it took time for the user to confirm the event. On the other hand, since the monitoring system 1 of the first embodiment executes the operation focusing on the specific state information on the process flow screen 4, the state information of the monitoring target 10 can be efficiently reproduced in time series. You can

The monitoring system 1 of the first embodiment changes the signal that the user is paying attention by linking a change in any state information that the user is paying attention to and a change in the reproduction speed for reproducing the state information. It is possible to perform reproduction with attention paid to.
The monitoring system 1 according to the first embodiment controls the change of the reproduction speed at the time of reproduction by relatively increasing the reproduction speed in the time zone in which the change rate of the state information is small and in the time zone in which the change rate is large. By making the reproduction speed relatively slow, the user can efficiently observe the state of the monitoring target 10 while shortening the time required for reproduction.
The monitoring system 1 according to the first embodiment slows down the reproduction speed in a time period in which the rate of change of state information is large. As a result, the user is less likely to miss a noticeable change in the state information of interest.

The reproducing unit 470 skips the reproduction of the state information associated with the unextracted time information, and reproduces the state information associated with the extracted time information.
The extraction unit 450 extracts time information about the plurality of monitoring targets 10.
The extraction unit 450 extracts the time information based on the rate of change of the value indicating the state information.
The extraction unit 450 extracts the time information indicating the time when the value indicating the state information is equal to or more than or equal to the threshold value (attention value).

The reproduction unit 470 reproduces the image information in time series on the process flow screen 4 of the display device 50 based on the process information acquired from the acquisition unit 460. When reproducing the image information as the status information in time series, the reproducing unit 470 reproduces the image information associated with the unextracted time information, when reproducing the image information associated with the unextracted time information. Playback is performed at a faster speed than when information is played back. The reproducing unit 470 may skip the image information associated with the non-extracted time information and reproduce the image information in another time zone.

As described above, the monitoring system 1 according to the second embodiment has the imaging device 60, the process information acquisition unit 440, the extraction unit 450, and the reproduction unit 470. The imaging device 60 images the monitoring targets 10-1 to 10-N and generates image information of the monitoring target. The process information acquisition unit 440 acquires process information in which status information indicating the status of the monitoring target, time information indicating the time when the status is reached, and image data are associated with each other. The extraction unit 450 extracts, from the process information, time information indicating the time when a predetermined event occurs in the state of the monitoring target. When reproducing the image information as the status information in time series, the reproducing unit 470 reproduces the image information associated with the unextracted time information, when reproducing the image information associated with the unextracted time information. Playback is performed at a faster speed than when information is played back.

The monitoring system 1 of at least one embodiment described above reproduces the extracted time information when reproducing the state information associated with the time information that has not been extracted when the state information is reproduced in time series. By providing the playback unit 470 that plays back at a higher speed than the case of playing the associated status information, the status information representing the status of the monitoring target in an arbitrary past period can be efficiently time-series. Can be played.
