Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention (Field of Industrial Application) The present invention relates to a learning plant simulator having a simulator for training plant operators.

(Prior art) A fixed explanatory text is created as a fixed screen for display, and a plurality of screens are prepared as many times as necessary for the explanation. On the other hand, in order to display this explanation screen during operation training, there are problems with fluctuations in plant status values, etc. and the timing of displaying the explanation screen. Conventionally, in order to display explanation screens during operation training, a display timing database was created that linked fluctuations in plant status values with the explanation screens to be displayed. During operation training, the constantly displayed timing database and plant status values are compared and monitored, and when it is determined that the plant status values set on the display timing database have been reached, the specified explanation screen is displayed on the CRT display. It was displayed above.

(Problem to be solved by the invention) However, in conventional learning plant simulators, the explanation screen is fixed, so even if the explanation content is the same, if the numbers or names that appear in the explanation differ, the explanation screen will not match. There was a possibility that it would disappear. Therefore, it was necessary to create separate explanation screens.

However, while the main status of the plant is being monitored, the timing database that specifies when to display cannot specify the timing of the internal logic calculation results of the control device, etc., so it is not possible to explain the equipment at detailed timing. In addition, since the screen to be displayed is directly designated by the screen number after a human (database creator) determines the management number on the screen database, there is a problem in that it is difficult to make a determination and is likely to lead to designation errors.

On the other hand, in order to display the explanation screen, the plant status is constantly monitored based on the timing database, and the screen is displayed when the plant status changes, so the plant monitoring process must be executed periodically. There was also the problem that the computer occupancy rate was high.

Therefore, in order to solve the above problems, the present invention can easily create a database for explanation screens, and incorporates timing processing for performing a simulated display on the display screen into the logic simulation calculation means, thereby reducing the load on the electronic computer. It is an object of the present invention to provide a learning plant simulator that can reduce the amount of energy required.

Another object of the present invention is to provide a learning plant simulator that is capable of displaying explanation screens at detailed timings that match plant conditions and has high learning efficiency.

[Structure of the Invention (Means for Solving the Problems) The present invention provides a plant simulation board on which trainees perform simulated operations while looking at lamps, indicators, switches, etc., and a plant simulation panel that edits the simulated state of the plant into an explanation screen. It consists of an electronic computer that performs calculations for the plant control system, and a learning console that allows simulated learning while viewing the explanation screen displayed on the CRT display. A logic simulation calculation means that simulates the functions of the CRT display and calculates the display timing of the explanation screen, a database for explanation screens divided into a plurality of blocks that makes it easy to edit the explanation screen of the CRT display, and a simulation using the logic simulation calculation means. A display screen calculation means for calculating the information displayed on the driving training explanation screen from the results and editing and calculating information from the explanation screen database, and a CRT of the learning console based on the display information of the display screen calculation means.
The present invention is characterized by comprising a display screen control means for displaying a driving training explanation screen on the display, and an operation content input means for requesting display of an explanation screen related to the explanation screen on the display using the keyboard of the learning console. .

(Operation) When the plant simulator of the present invention is operated, the information instructed on the plant simulator board is inputted to the logic simulator calculation means via the board-like front input means, and the plant simulator logic calculation is performed. The output signal from the logic simulation calculation means triggers the display screen calculation means. As trigger information, the PID and the result of the logic simulation calculation means are passed in a logic state.

The triggered display screen calculation means 1-Rigger information'
Based on this, the explanation screen display database is parsed and item data corresponding to the 1gc property is selected. In addition, the plant status is taken from the trigger information, the plant status value and the explanatory screen data corresponding to the characteristics are selected from the screen database, and editing operations are performed to set the above values in the explanatory text according to the data structure. Do this. Then, based on the result of this editing calculation, a request is made to the display screen control means to display an explanation screen, and the explanation screen is displayed on the CRT display.

(Embodiment) FIG. 1 is a block diagram of a learning plant simulator according to an embodiment of the present invention.

In the case of an attribute for pump type a, a sentence is created that matches each logic state of the display timing logic result for that pump type. This text includes a commonly usable text and a part marked rt[]pt, and ll[]11 means setting individual data, as shown in Figure 2. The numbers in parentheses shown in the figure indicate the word, number, or type of sentence to be set at the position of the sentence. The PID attribute database d2 shown in FIG. 1 is created by assigning attributes to each PID.

This PID, @characteristic database d2 is used to set attributes (pump type, valve type, etc.) for all PIDs of the plant. As an example thereof, FIG. 3 shows a P-dori attribute database.

The attribute item database d3 shown in FIG. 1 is created by setting the constituent elements of each attribute. This attribute item database d3 is a database prepared for each attribute assigned to the PIDg data database. Contains the settings necessary to configure the attribute. As an example, an attribute item database is shown in FIG. This defines the functions of the constituent elements in the structured database. d4
