Description

  The present invention relates to a display device that displays a monitoring state by a controller.

  A temperature controller that adjusts the temperature of various temperature environments, etc., displays the temperature of the monitoring target detected using a temperature sensor such as a thermocouple or resistance temperature detector, and the detected temperature (PV value). A control output (MV value) for the heating / cooling device is obtained according to the set temperature (SP value), and the temperature to be monitored is controlled. By the way, the temperature controller cannot enlarge the area which displays each information for size reduction.

  For this reason, trend graphs showing time-series changes in measured values can be confirmed on the trend screen on the monitor of small computer devices such as personal computers, tablet terminals, and smartphones connected to the controller. (See Patent Document 1). On the trend screen, the setting state of the controller, changes in measured values, etc. are displayed in a table or graph. For example, as shown in FIG. 4, changes in the temperature measurement results for two monitoring targets are shown in a graph in a region 401. In addition, a result of measuring a value outside the set numerical range is displayed in a timing diagram as an alarm on / off change in region 402. In addition, it is configured such that the controller setting can be changed by a connected computer device.

  However, in the above-described trend screen, there is a problem that it is not possible to easily determine whether the measurement value is correctly related to the setting and the result reflecting the setting, and the cause of the measurement result. For example, a temperature controller has a standby operation (see Patent Document 2). The standby operation is an operation that does not output an alarm when the temperature controller is initially operated or when the control target device is started up. However, it cannot be confirmed on the trend screen that the vehicle is on standby during operation.

  For this reason, for example, the measured value displayed in the graph on the trend screen shows an abnormal value that exceeds the setting range known to the operator, but the alarm may not be displayed as an on state. Whether or not this state shows an abnormal value due to a setting error or malfunction of the temperature controller, or whether there is no problem because it is in standby operation even if it is an abnormal value, it can be distinguished only by looking at the trend graph. Can not. As described above, conventionally, there is a problem that it is impossible to intuitively determine the relationship between a setting that is a measured value and the measured value simply by looking at the result at a certain point in time.

FIG. 1 is a configuration diagram showing a configuration of a display device according to an embodiment of the present invention. FIG. 2 is a configuration diagram showing a display example on the display unit 108 of the display device according to the embodiment of the present invention. FIG. 3 is a configuration diagram illustrating a display example on the display unit 108 of the display device according to the embodiment of the present invention. FIG. 4 is a configuration diagram showing a display configuration of a conventional display device.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a configuration diagram showing a configuration of a display device according to an embodiment of the present invention. The display device, the measured value graph generation unit 101, an event generator graph generation unit 102, the setting range graph generation unit 103, a standby state detection unit 104, wait status display generation unit 105, the display control unit 106, a display unit 108, And an input unit 109.

  The measured value graph generation unit 101 generates a measured value change graph that shows changes in measured values measured by the monitoring target in time series. The event occurrence graph generation unit 102 generates an event occurrence display graph indicating whether or not an event has occurred with a timing diagram in association with a change in the measurement value on the same time scale as the measurement value change graph. The event is generated from an event generation unit (not shown). The event generation unit detects a measurement value that falls within the numerical range set for the occurrence of the event and generates an event. The event is, for example, an alarm.

In addition, the setting range graph generation unit 103 generates a setting range display graph indicating the numerical range on the measurement value axis having the same scale as the measurement value change graph. Further, the standby state detection unit 104, the detection of the operating state of the monitored object that matches the conditions that are set, detect whether the standby state does not output an alarm for the monitored regardless occurrence or non-occurrence of an event To do. Wait status display generation unit 105, a standby state detection unit 104 generates a standby state indication indicating the wait state detected.

The display control unit 106, a measurement standby state display graph generation unit 101 is measured value change graph and waiting status display generation unit 105 to generate the simultaneously generated, and displayed as the trend screen on the display unit 108. The display control unit 106 also causes the display unit 108 to display the event generation display graph generated by the event generation graph generation unit 102 and the setting range display graph generated by the setting range graph generation unit 103.

  For example, as shown in FIG. 2, a measurement value change graph is displayed in the measurement value change display area 121 of the display unit 108, and an event occurrence display graph (timing diagram) is displayed in the event occurrence display area 122. In the example shown in FIG. 2, a graph indicating a time series change of two temperature measurement values is displayed as a part of the trend screen. Further, in the example shown in FIG. 2, with respect to the time series change of one measurement value, the event occurrence graph 131 indicating whether or not the alarm 1 is generated, the event occurrence graph 132 indicating whether or not the alarm 2 is generated, and whether or not the alarm 3 is generated Is displayed as a part of the trend screen.

  In addition, a setting range display graph is displayed in the setting range display area 123 of the display unit 108. In the example shown in FIG. 2, a range graph 141 indicating the numerical range set for the alarm 1 issuance, a range graph 142 indicating the numerical range set for the alarm 2 issuance, and the numerical range set for the alarm 3 is shown. A range graph 143 shown is displayed as part of the trend screen.

  In the example shown in FIG. 2, a dead zone set for each numerical value range is also shown. For example, regarding the setting range for alarm 1, the range graph 141 indicates that 100 to 110 ° C. is set as the dead zone for the upper limit. Further, regarding the setting range for the alarm 2, the range graph 142 shows that the lower limit is set to 50 to 60 ° C. and the upper limit is set to 80 to 90 ° C. as the dead zone. In addition, regarding the setting range for the alarm 2, the range graph 142 indicates that the lower limit is set to 30 to 40 ° C. and the upper limit is set to 130 to 140 ° C. as the dead zone.

  Further, in the example shown in FIG. 2, a numerical value display of a numerical value range is displayed in each range graph under the control of the setting range graph generation unit 103. As described above, the setting range graph generation unit 103 may generate a setting range display graph including a numerical value display of the numerical value range and display it.

In addition, in the example shown in FIG. 2, the wait status display area 124, the standby status is displayed. Here, an indicator indicating whether or not the state is in a standby state is displayed corresponding to each alarm setting range display graph displayed in the setting range display area 123.

  As described above, by displaying the setting range display graph, it is possible to instantaneously determine the relationship between the setting value related to the event occurrence, the range of the measurement value where the event occurs, and the measurement result. . Further, as described above, the number of events such as alarms is not limited to one, and a plurality of event occurrences set for the same measurement value may be displayed simultaneously. In this case, the event occurrence graph generation unit 102 generates an event generation display graph indicating whether or not a plurality of events have occurred, and the setting range graph generation unit 103 sets the setting ranges corresponding to the plurality of events to different display states. Generate the set range display graph.

  In the embodiment, since the standby state is displayed with an indicator or the like in accordance with the setting range display graph indicating each event occurrence condition, it is possible to confirm that the standby state is on the trend screen. For this reason, for example, the measured value displayed in the graph on the trend screen indicates an abnormal value that exceeds the setting range that the operator knows, but the alarm is displayed as on because it is in a standby state. You will be able to recognize at a glance that you are not.

  The display device also includes a delay state detection unit 111 that detects that the measured value is in a delay state, and a delay that generates a delay display that displays the delay state detected by the delay state detection unit 111. A display generation unit 112. When detecting the delay state, the delay state detection unit 111 detects the elapsed time of the detected delay state. The delay display generation unit 112 generates a delay display indicating the elapsed time of the delay state.

  When the delay display generation unit 112 generates a delay display, the display control unit 106 simultaneously displays the generated delay display in addition to the measurement value change graph, the event generation display graph, the setting range display graph, and the standby state display. 108 is displayed.

  For example, as shown in FIG. 2, an off-delay state is displayed in the delay state display area 125. Here, in correspondence with the alarm setting range display graph displayed in the setting range display area 123, the elapsed time in the delay state is displayed as a bar graph in addition to the off-delay state. For example, for a warning in the delay state, the color of the bar changes with time while the background is white. On the other hand, for warnings that are not in the delay state, the bar color is gray.

  When the off-delay is set, it does not turn off immediately even if it is within the alarm off point range. If the off-delay time is about several seconds, it can be understood that the effect is caused by the operator monitoring the trend screen. However, in the case of a long delay, it is necessary to check the setting and the like in order to know why it is not turned off when this state is viewed later. On the other hand, as described above, if the delay state is shown on the trend screen, the operation state can be confirmed instantaneously.

In addition, the display device includes a time connection line generation unit 113 that generates a line perpendicular to the time axis indicating the time when an event occurs in a measurement value change graph in a state where the line is connected to the event generation display graph. When the time connection line generation unit 113 generates a time connection line, the display control unit 106 displays the generated time connection line in addition to the measurement value change graph, the event occurrence display graph, the setting range display graph, and the standby state display. At the same time, it is displayed on the display unit 108. For example, as shown in FIG. 2, a time connection line 161 by a dotted line is displayed from the measurement value change display area 121 to the event occurrence display area 122. By doing so, the time-series relationship between the change in the set value and the event occurrence timing becomes easier to understand.

In addition, the display device includes a numerical connection line generation unit 114. The numerical value connection line generation unit 114 generates a line parallel to the time axis indicating the numerical value range where the event occurs in the measurement value change graph in a state where the line is connected to the setting range display graph.

  When the numerical connection line generation unit 114 generates the numerical connection line in this way, the display control unit 106 simultaneously generates the generated numerical connection line in addition to the measurement value change graph, the event occurrence display graph, and the setting range display graph. It is displayed on the display unit 108. For example, as shown in FIG. 2, a dotted line 162 is displayed from the setting range display area 123 to the measurement value change display area 121. By doing so, the relationship between the set value and the measurement result becomes easier to understand.

The display device also includes a measurement value graph display changing unit 115. The measurement value graph display changing unit 115 divides the measurement value change graph using the line generated by the numerical value connection line generation unit 114 as a boundary line, and the area in the divided measurement value change graph is the same as the corresponding event occurrence display graph. Change to display state.

Thus, when the measurement value graph display change unit 115 changes the display, the display control unit 106 causes the display unit 108 to display the measurement value change graph changed by the measurement value graph display change unit 115. For example, as shown in FIG. 3, the range 151 of the measurement value change display area 121 indicating the range of the range graph 141 is displayed in the same color as the range graph 141. Further, the range 152 of the measurement value change display area 121 indicating the range of the range graph 142 is displayed in the same color as the range graph 142. Further, the range 153 of the measurement value change display area 121 indicating the range of the range graph 143 is displayed in the same color as the range graph 141. Each display color is a different color so as to be identifiable. By displaying in different colors in this way, the relationship between the set value and the measurement result becomes easier to understand.

As described above, according to the present invention, a setting range display graph indicating a numerical range is generated on the measurement value axis having the same scale as the measurement value change graph in which the change of the measurement value is displayed. among the displayed together. Thus to display the standby status display showing the wait state at the same time, the relationship between the measurement result and the current setting displayed on the trend screen, easily confirm the user become able to.

  In the conventional trend screen, in order to confirm whether the setting, the result reflecting the setting, the measurement result, and the relationship between these results are correct or the reason for the result, rely on the memory of the setting. However, it was difficult to intuitively judge whether the condition was good or bad. Even if the set value is displayed, it is an enumeration of numbers, and it is difficult to intuitively know the relationship between the monitor value and the set value even if the trend screen graph and the numerical value are arranged.

Intuitively knowing how all the settings are, especially when the alarm deadband operation, standby state , on-delay, and off-delay, which are unique to temperature controllers, are used. This is important to prevent setting errors. However, conventionally, it has not been possible to intuitively determine the relationship between the setting and the measurement value that are causing the current alarm result.

  On the other hand, according to the present invention, the setting range can be intuitively understood on one screen in addition to the current measured value and alarm state without separately checking the numerical value of the setting. Compared with the measurement results, it is possible to significantly prevent work efficiency and mistakes from being confirmed.

  The present invention is not limited to the embodiment described above, and many modifications and combinations can be implemented by those having ordinary knowledge in the art within the technical idea of the present invention. It is obvious. In the present invention, it is important to display the measurement value change graph and the standby state display simultaneously as a trend screen on the display unit under the control of the display control unit, and the setting range display graph, event occurrence display graph, off-delay state Display, connecting lines, color coding of ranges, and the like can be combined as appropriate.
