Description

  Embodiments described herein relate generally to a monitoring control method, a monitoring control apparatus, and a monitoring control system that notify an operator of a monitoring history of various facilities.

  Conventionally, in a monitoring control system that supports monitoring of various facilities such as buildings, a change in the state of a signal from a monitored part is detected, and an operator is monitored through a monitoring screen display device such as a monitor or an alarm ringing device. The equipment status is displayed and alarms are notified.

  In addition, these monitoring and control systems detect changes in the state of signals obtained from monitored devices, occurrence / recovery of faults / alarms, setting operations by operators, etc. as events, and store them as history data of the monitoring control system. ing.

  The operator can call up the history list screen and check the history of events that occurred in the past in chronological order. The history list also shows the ID, name, alarm grade, and monitoring classification of the point where the event occurred, the cause of the event (such as the name of the automatic control function and the name of the machine on which the operator performed the setting operation), and the occurrence of the event. The history to be displayed can be narrowed down depending on the period of time.

  In a supervisory control system, when a device breaks down or a fault exists in the system, a specific event such as an alarm or a failure occurs continuously at a plurality of points, or a specific automatic control is performed. It is possible that a specific event such as an alarm will occur at a certain point, and when analyzing the cause of a device failure or system failure, the history is narrowed down to identify the failure or failure. The occurrence status may be confirmed.

  However, with the conventional history list narrowing function, the point ID / name / monitoring classification, generation factor, etc., for the history of a plurality of points (or a combination of the history of a point and the history of a cause) Depending on the conditions, it is not possible to narrow down and display on the history list screen at once, and it is necessary to display a plurality of individually narrowed history lists, and the operator manually matches the contents of each history list.

  In addition, the input unit 131 uses the CPU 100 that executes the history group management program 154 in accordance with an operator's operation to narrow down narrowing items (data in which a plurality of point IDs and history generation factors are associated as history groups). The event notification condition is registered in the event notification condition table 164 and the event notification content is registered in the event notification content table 165.

  In addition, the input unit 131 causes the history list display program 155 and the history data management program 152 to be executed according to the operation of the operator, and causes the display unit 141 to display a history list screen of data registered in the history table 161.

  The display IF 140 is an interface that connects the display unit 141 and the monitoring control device 10. Display control of the display unit 130 may be performed from the CPU 100 via the display IF 141, or display control may be performed by an LSI (GPU) that performs drawing processing such as a graphic board. It may be configured to be directly connected to the monitoring control apparatus 10 without using the IF.
