Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a training simulator for operators who operate oil refining, petrochemical, and other plants.

In general, this type of plant has controllers that control physical quantities such as temperature, pressure, and flow rate, as well as switches and gate valves that start and stop operating equipment such as pumps and compressors, and are displayed on indicators, recording needles, etc. It is operated by setting it corresponding to the actual physical quantity. Therefore, in the 7 simulators for training operators of these plants, the above-mentioned adjustment needles, switches and indicators,
The adjusting needle, switch, indicator, recorder, etc. corresponding to the recording needle etc. can be integrated or divided as necessary, /Q
installed in a predetermined position on the wall. Then, control 1 signals from controllers, switches, etc. are taken into the computer,
A simulation model device in the computer calculates and outputs a signal substantially equivalent to a signal output when the actual plant operates, and the result is output and displayed on an indicator, recorder, etc.

In such a training simulator, depending on the training or purpose of a beginner, it is not necessarily efficient to operate and train all the functions of the simulator corresponding to the operation of the entire plant. Therefore, it is preferable to use a method that allows for easy partial changes in the equipment configuration of the plant to be tested, as well as additional changes to specific devices, devices, instruments, etc.

By the way, the control needles, switches, indicators, recorders, etc. are designed for use in training for a single target plant as a whole. In some cases, the instrumentation arrangement may be a hindrance to training.

In conventional simulators, in such cases, methods such as reconnecting the wiring between the above-mentioned components and the computer, making some changes, or installing separate panels for each plant to be trained are carried out. It is. The former method requires considerable effort to change the connections, and is not practical due to the complexity of the wiring. Furthermore, the latter method requires a plurality of cables and is more expensive, which is undesirable. It is an object of the present invention to provide a simulator for plant filtration that allows changing target instruments for input/output on a wall in a simple manner, that is, enabling the replacement of instruments.

That is, the present invention provides an operating end corresponding to a controller, an operating switch, etc. of a device that controls an actual plant, and an input from the operating end (based on = -e, a signal output when the actual plant operates). In a plant training simulator consisting of a simulation model device that outputs similar signals and a display device that displays the output signals of the simulation model device, the input signal from the operating end and the output signal to the display device The simulation model device and the input/output data storage device are stored based on data on the correspondence between the input/output signal positions in the input/output data storage device and the input/output signals of the simulation model device. and an input/output control device that manages input/output signals between the two, and by modifying the correspondence data in the management data storage device, it is possible to change the input/output target operation end and display of the input/output signal. This is a training simulator designed to

The present invention will be explained below based on figures of preferred embodiments.

Preferably, an RT display device is used. The command device 3 for the trainer gives necessary instructions to the simulation model device #4, such as starting and stopping the operation of the simulator, or the occurrence of a trouble.

The simulator body 8 uses a computer, and includes a simulation model device 4, an input/output data storage device 5,
Input/output control device 6 and management data storage device 7
Contains.

The simulation model system @4 is configured to output the same signal as when the actual plant operates based on the control signal, and includes a group of unit models that perform calculations corresponding to each device of the plant, and each unit model. Characteristic data table and inter-unit data table corresponding to
It also includes a simulation control section that manages the unit model u.

Input/output data storage device 5t'i, which temporarily stores input signals from the operating end l and output signals to the display 2;
It is made into a table. The positions where these input/output signals are temporarily stored correspond to each of the operating end 1 and the display 2 on a one-to-one basis.

The input/output control device 6 is the input/output data storage device 5
After reading out the input signal 1 and performing signal processing such as analog-to-digital conversion, the data at a predetermined position in the characteristic data table in the simulation model device 4 is rewritten based on the data in the management data storage device, and the data is converted into a correspondence. , extracts data of predetermined simulation results from the characteristic data table in the simulation model device 4, and converts it into a digital
It has a function of performing signal processing such as analog conversion and rewriting the output signal at a predetermined position in the input/output data storage device 45 based on the data in the management data storage device.

The management data storage device 7 stores data on the correspondence between the positions of input/output signals in the input/output data storage ladder '5 and the input/output signals of the simulation model device 4. More specifically, the simulation model device 4
Which position in the input/output data storage device 5 should the data in the characteristic data table in the input/output data storage device 5 be output to? This is a data representation of how much money is being put in. The data in this 1Prf property data table and the data in the input/output data storage device 5 do not necessarily have to be in a one-to-one correspondence; In some cases, it corresponds to the data of Conventionally, this simulation model system [
The relationship between the input/output signals of 4 and the input/output signals of the input/output data storage device 5 was incorporated in the simulation model device 4 as an input/output management program. Therefore, in order to change the correspondence relationship between the input/output signal 6 of the input/output data storage device 5 and the input/output signal of the simulation model device 4, it is necessary to modify the program, and in practice, various changes are required for each training. is impossible. However, in the present invention, since this correspondence relationship is stored as data in the τ management data storage device 7, the correction can be made extremely easily by simply modifying this data. Therefore, since the position of the input/output signal of the input/output data storage device 50 can be changed, this position and 1

and A2 have been exchanged. By modifying the management data storage device 7, it is possible not only to replace the operating end or the display, but also to easily add, remove, or stop some functions of the operating end or the display.

The operating mode of the training simulator with the above configuration will be described below.

The simulator is activated by a command signal from the trainer's command device 30. The control signal from the operating end 10 is temporarily stored as an input signal at a predetermined position in the input/output data storage device 5. This input signal is read out to the input control device #6, where it is converted from analog to digital, etc., the data from the management data storage device 7 is read out, and based on the data, a predetermined position in the characteristic data table of the simulation model device 4 is read out. temporarily memorized. Next, in the simulation model device 4, the data of the characteristic data table and the inter-unit table are read out to the unit model, and the result is temporarily stored in a predetermined position of the characteristic data table. The data temporarily stored as a result of this simulation is read out to the input/output control device 6, and after processing such as digital-to-analog conversion, the data in the management data storage device 7 is read out, and based on this data, the input/output data storage device 5 is temporarily stored as an output signal in a predetermined position. This is displayed on the display 2. The above operations are scanned at appropriate intervals, for example, at 1 second intervals.

In the actual 111 training, the trainer instructs the simulation model device 4 from the trainer's command device 3 about the occurrence of a trouble, such as a pump failure or a misfire in the heating furnace. Then, the unit model group of the simulation model device 4 performs the corresponding calculation and is displayed on the display 2 along the path as described above. The trainee confirms the abnormality based on the display on the display 2, changes the settings of the operating end 1 in response to the abnormality, and restores the normal state. Full M is performed through this process.

By the way, when training is performed not on the entire plant but on some equipment or parts, the trainer t sends the following information from the trainer command device 2 to the management data storage device 7.
Training can be performed in any combination by specifying a desired operating end, display, and device and instructing data modification. Further, depending on this combination of wildflowers, the simulator can correspond to completely different plants, which means that training for various plants can be performed using one simulator.

As described above, the present invention makes the correspondence relationship between the storage position of the input/output signal in the input/output data storage device and the input/output signal of the simulation model device independent from the program and converts it into data. Alternatively, the target input/output signals of the display can be easily changed. Therefore, the simulator of the present invention can perform training with any equipment, and furthermore, can perform simulations corresponding to various processes with one simulator.
This has the excellent effect of increasing the efficiency of training.
