Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an operation support device applied to a control panel of a plant.

[Conventional technology]

In conventional plant control, operators read information from indicators, indicator lights, and CRT screens on the control panel.
The plant was controlled by operating the controllers on the control panel.

In this case, the pointer, indicator light, and operating device on the control panel were fixed, and the operator had to make his own judgment in selecting the equipment. In addition, the CRT screen was also changed manually by the operator.

[Problem to be solved by the invention]

In transient states of the plant, such as when the plant is in the process of starting or stopping, or when the plant becomes abnormal and needs to be transitioned to a safe state, plant operators must recognize and judge the state of the plant before operating the plant. It won't happen. Therefore, the plant control panel must be equipped with a human interface that allows operators to recognize, judge, and operate the plant status in the most appropriate manner at such times.

However, in conventional control panels, operators use indicators,
Because the system read information from indicator lights and CRT screens to recognize and judge the status of the plant, it was not always possible to make appropriate decisions and operations.

In order to solve the above-mentioned problems, the present invention replaces fixed instruments on the conventional control panel and manual CRT screen switching.
The data necessary for recognition and judgment is automatically output according to the plant status, and important information or information that is easily misunderstood is presented via multiple media to improve the accuracy. The present invention proposes a device that automatically presents a control panel to be operated on a CRT screen so that an operator can easily operate it.

[Means for Solving the Problems] The operation support device of the present invention includes a plant state determining means for inputting plant state data, a sequence selecting means for inputting a determination result from the determining means, and an operation support system for an operator from the selecting means. Operator position detection means, important item selection means, and human error rate evaluation means for inputting recognition, judgment, and operation items to be performed and their order, and important item selection means for inputting the operator position from the operator position detection means. media selection means for inputting more important items and inputting the human error rate from the human error rate evaluation means; and media control for inputting the media selected by the selection means, outputting information necessary for operation, and accessing operator operation signals. It is characterized by having the means.

[Operation] In the above, the plant state determining means inputs the state such as the temperature and pressure of the plant and determines what state the plant is currently in.

The sequence selection means to which this judgment result is input sets the recognition, judgment, and operation items to be performed thereafter and their order based on the judgment result.

The operator position detection means for detecting whether the operator is in front of the control panel or away from the control panel inputs the above-mentioned operation items and outputs the detection results.

Further, the important item selection means into which the above-mentioned operation items and the like are input selects particularly important items from among the recognition, judgment, and operation items set by the sequence selection means.

Furthermore, the human error rate evaluation means selects items with a high human error rate from among the recognition, judgment, and operation items set by the sequence selection means.

The media selection means inputs the outputs of the operator position detection means, important item selection means, and human error rate evaluation means,
Select media for recognition, judgment, and manipulation based on each output.

The media control means that receives the media selected by the media control means uses the media selected by the media selection means to provide necessary information to the operator and access operator operation signals.

With the above, the provision of information to the operator can be automatically controlled, and the information necessary for the operator's recognition, judgment, and operation can be presented via appropriate media, reducing the burden on the operator and improving driving efficiency. Confidence can be improved.

〔Example] An embodiment of the present invention is shown in FIG.

The present embodiment shown in FIG. 1 consists of a plant state determining means 1 for manually inputting plant state data, a sequence selecting means 2 for inputting determination results from the determining means, recognition to be performed by an operator from the selecting means 2, Operator position detection means 3, important item selection means 4, human error rate evaluation means 5, inputting judgment and operation items and their order, respectively; and important item selection means for inputting the operator position from the operator position detection means 3. A media selection means 6 inputs important items from 4 and inputs a human error rate from the human error rate evaluation means 5, and a media selection means 6 inputs the selected media from the selection means 6 to provide necessary information to the operator for operator operation. It is equipped with media control means 7 for accessing signals.

In the above, the plant state determination means 1 takes in the state of the plant such as temperature and pressure, and determines what state the plant is currently in. The sequence selection means 2 that receives the judgment results sets the recognition, judgment, and operation items to be performed by the operator from now on, and their order, based on the plant state judgment results. This is done by determining a sequence corresponding to the plant state in advance and referring to it as needed. The operator position detection means 3 detects whether the operator is in front of the control panel or away from it.

The important item selection means 4 selects important items from the viewpoint of plant safety, operation rate, etc. from among the recognition, judgment, and operation items set by the sequence selection means 2.

Human error rate evaluation, means 5, sequence selection means 2
Among the recognition, judgment, and operation items set in , select items with a high human error rate. This is done by assigning human error rates to all recognition, judgment, and operation items in advance.
This is done by referring to the error rate of the item selected at each time point. The media selection means 6 selects media according to the following rules.

That is, if it is detected that the operator is away from the control panel as a result of detection by the operator position detection means 3, the CRT
Providing information on a screen is meaningless, so information is provided by voice. Operations are also performed by voice in the same way.

Furthermore, for the items selected by the important item selection means 4, media are multiplexed. For example, it provides information in audio and text, or displays current values and future forecast trend graphs.

Furthermore, for the items selected by the human error rate evaluation means 5, media are multiplexed in the same manner as above.

The media control means 7 uses the media selected by the media selection means 6 to provide necessary information to the operator and access operator operation signals.

With the above, the provision of information to the operator can be automatically controlled, and the information necessary for the operator's recognition, judgment, and operation can be presented via appropriate media, reducing the burden on the operator.
Driving reliability can be improved.

〔Effect of the invention〕

The operation support device of the present invention sets recognition, judgment, and operation items and their order based on the judgment result of the plant state, evaluates and selects each item, and then selects an appropriate medium.
By outputting information necessary for operation and accessing operator operation signals, the information necessary for operator recognition, judgment, and operation can be presented via appropriate media, reducing the burden on the operator and increasing confidence in operation. It can improve convertibility.
