Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an equipment status monitoring and displaying apparatus for performing centralized monitoring display based on status monitoring information of a monitored apparatus.

[0002]

2. Description of the Related Art In a facility status monitor and display device for performing centralized monitor display of monitored devices such as various production facilities and plants, the size and structure of the facility and the system are complicated, and are therefore targeted by operation supervisors. The number of condition-monitored devices and their scores are very large. Therefore, the burden on the operation supervisor is reduced and the working capacity is improved, and the system is monitored by displaying the fixed information and the monitored process status on the display device for each monitored device and device group. Signal due to changes in temperature, equipment failure monitoring,
Regarding monitoring of signal status changes, it is common to display a list of failure alarm signal-related items and signal change information in a chronological order by date, time, signal name, and device group name. Is.

[0003]

This type of equipment status monitor and display device determines the equipment status based on the monitoring information displayed on the operation status screen, such as the operating status, alarm signals, and failure signals of the monitored equipment. It is something. However, when monitoring an operation stop signal, an alarm signal, and a failure signal, it is necessary to search for a device in which an alarm or a failure has occurred, from the fact that the number of points is thousands, and the equipment operation It interferes with quick decision.

Moreover, in monitoring the operation stop signal, the alarm signal and the failure signal displayed on the operation status screen of the equipment, the date and time of occurrence and the name of the alarm failure signal are collectively displayed in time series in the range of all the equipment. In this case, the display range of the state change signal, the alarm, and the failure signal extends over a wide range, which makes it difficult to grasp the state of each device and delays the response or makes an incorrect response.

Therefore, the object of the present invention is to improve the monitoring capability and the monitoring performance by displaying the designated device group status change in the overall status change condition which is always displayed on the monitor screen in an overlapping manner. Another object of the present invention is to provide a special equipment state monitoring and display device with a reduced monitoring load.

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and has the following structure. That is, a display device such as a CRT, an input device such as a keyboard attached to the display device, and device-specific status monitoring data of a monitored device are stored by a data collecting means via a communication line. Monitoring data storage device, signal group name related data device, device group name definition data storage device, and monitoring classification data storage device connected to the monitoring data storage device.
At least data retrieving and classifying means, and the monitoring data retrieving and classifying means obtains the state change data and the alarm data based on the state change data from the monitoring data storage device, and
Overall state change data based on signal group name related data and device group name definition data and state change data for each device
Data is stored in the monitoring classification data storage device, the state change data for each device is read from the input device via the input means by the device group name, and is displayed on the display device by the output means. It is composed.

The action and effect obtained by such a solving means are as follows. In the equipment state monitoring display device, the equipment monitoring screen is selected by the operation of the operation supervisor, the screen data is retrieved by the screen storage means, and the designated screen is displayed on the display device. This monitoring screen display method is a general method. Here, the monitoring points and the monitoring data are periodically collected by the data collecting means through the communication line connected to the monitored device and stored in the monitoring data storage device.
For the monitoring data, a signal state change display designation, an alarm signal designation or a fault signal designation, a signal name and a device group name for signal generation are set from the information input device through the input means, and the signal group is set. It is stored in the name-related data storage device. As the signal group name, the signal group name previously input to the device group definition table by the information input device is input and stored. Next, the monitoring data search / classification means detects a change in the status of the monitoring data stored in the monitoring data storage device, and creates data classified by the device of the signal group name. Then, it is stored as state change data for each device. At the same time, the overall state change data is also stored in the monitoring classification data storage device.

As a result, the overall state change data can be displayed on the fixed position of the equipment monitor screen previously displayed by the output means at the same time as the state change occurs. Furthermore, by specifying the name of the monitored device from the input device as the name existing in the device group definition table, the status change data for each device is read from the monitoring classification data storage device and displayed on the monitoring screen. -It can be displayed by overlapping. The displayed status change data is only a series of status changes to be monitored, a failure, and an alarm signal to be displayed in a designated device group. Also, the status change data
The data can be erased from the monitor display screen by pointing the designated position with the input means, and the monitor can be continued by returning to the original screen.
