A conventional monitoring device is configured as described above,
The drawing input means 1 inputs, for example, a drawing as shown in FIG. 3 to create a table as shown in FIG. 4 and stores it in the drawing storage means 2. In this drawing, symbols S1 to S5 are tanks,
It represents a device such as a pump, and connection lines 11 to 17 represent pipes connecting the devices. On the other hand, the operating state measuring means 3 periodically measures the operating state of each device, such as pressure, temperature, and water level, for example, once a minute, creates a table shown in FIG.

Here, it is assumed that a pressure abnormality has occurred in the pump S1. The system detects that an abnormality has occurred in the device S1 by comparing the measurement result data stored in the measurement result storage unit 4 with a preset standard value. Further, the device S
6 is read out by the display means 7 by reading out the drawing data including
The drawing is displayed on a CRT screen or the like as shown in 7a. At this time, since one plant is generally composed of an enormous number of devices, the drawing is divided into several sheets. In addition, each drawing is usually large enough to be displayed on a normal CRT screen.

Therefore, in the drawing reading means 5,
With respect to the drawing including the corresponding device S1, a process of cutting out a range of a size that includes the device S1 and can be displayed on the CRT screen is performed. Further, a symbol corresponding to the device S1 is drawn by a thick line so that the operator can confirm the symbol. Further, the measurement result reading means 6 reads the measurement result data relating to the corresponding device S1, and displays the data as shown in FIG. 67b by the display means 7.

Next, the operator starts work for investigating the cause of the abnormality. Generally, when a failure occurs in one device, an abnormality occurs in another device due to the failure, and the abnormality is linked to a plurality of devices. Therefore, the operator follows the chain in reverse, starting from the equipment in which the abnormality is detected, and sequentially confirms the measurement result data for those equipment. For example, assuming that the device affecting the pump S1 is the tank S2 and the devices affecting the tank S2 are the valve S5 and the filter S3, these related devices are listed in the related device correspondence table 9 as shown in FIG. Have been.

On the other hand, the screen request means 8 is constituted by, for example, a button on a panel. When the operator presses the button while the information on the device S1 is displayed, the system refers to the related device correspondence table 9 and Next, the user knows that the device to be displayed is S2, and displays the drawing and measurement result relating to S2. Further, every time the operator presses the button, the screen sequentially displays information on S5 and information on S3. As described above, the operator can sequentially obtain information on related devices by pressing the push buttons one after another.

[0009]

The conventional monitoring apparatus is configured as described above. However, since the devices listed in the related device correspondence table are generally enormous due to the branch-like chain, they are sequentially displayed. There is a problem that the operator tends to lose track of the sequence on which the displayed screen is displayed.

[0010] The present invention has been made to solve the above problems, the equipment operator is linked to branched
It is an object of the present invention to obtain a monitoring device that makes it easy to grasp the state of a chain when sequentially referring to information on monitoring elements including the monitoring elements.
