Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a simulation control device 2 used for operation training of general plan mills and the like.

[Technical background of the invention and its problems] As plants and the like have become more complex in recent years, their control operations have also tended to become more and more complex. For this reason, it is desirable to be able to perform control operation training for plants, etc. in accordance with the actual situation, and various functional improvements have been made to simulate control devices to fully meet these demands. . In general, a simulation control device is comprised of an electronic computer that has the function of simulating the dynamic characteristics and logic sequences of an actual machine, and a simulation control panel that controls, operates, and monitors the computer. Furthermore, regarding the logic sequence, there are cases where everything is converted into software and electronic calculations control the functions.
Due to computer capacity constraints and economic efficiency, only those circuits that require quick response, such as selection switching circuits and alarm circuits, are constructed in a relay sequence in a simulated control panel, and the rest are processed by an electronic computer.

By the way, in order to improve training efficiency, a simulation control device is required to have a function of arbitrarily reproducing the operating conditions of several types of typical plants. In this case, if all the logic sequences are converted into software, typical plant conditions can be displayed on the simulation T2II panel without any restrictions according to predetermined setting inputs, but the amount of software would be enormous, so The burden on the computer is large, the calculation processing time is long, and the equipment is also very expensive. Therefore, in view of this problem, it is conceivable to configure part of the logic sequence as a relay sequence as described above, but on the other hand, it is possible to configure a part of the logic sequence as a relay sequence as described above. In this case, it is not possible to control the selected device display, alarm display, etc., and the settings must be made manually, resulting in the problem of half-opening.

[Object of the Invention] The present invention has been made in view of the above, and an object of the present invention is to provide a simulation control device that allows state setting to be performed easily and in a short time.

[Summary of the Invention] In order to achieve the above object, the present invention provides a device for simulating the action of a controlled object according to driving operations, as shown in FIG. a state display means 51; a first calculation means 53 which is composed of a logic sequence and calculates an output for setting a simulated state of the controlled object according to the display; a second calculation means 55 that calculates an output for setting a simulated state; and a state setting means 57 that simulates the state of the controlled object based on the outputs from the first calculation means 53 and the second calculation means 55.
The gist is to have the following.

[Embodiments of the invention] Hereinafter, the present invention will be explained in detail using the drawings.

FIG. 2 shows the configuration of a simulation control device according to an embodiment of the present invention. This simulation control device includes a calculation unit 1 that simulates the dynamic characteristics and logic sequence of the actual machine, and a simulation control panel 3 that controls, operates, and monitors the plant status set under the control of the calculation unit 1. It is the composition.

The simulated control panel 3 is configured to correspond to an operation section 5 through which the trainee performs various control operations according to the set plant status, and circuits that require quick response such as a selection switching circuit and an alarm circuit. , receives an operation signal from the operating section 5 or a plant state setting signal from the computing section 1 and sequentially controls the plant state, or according to the sequence control in the relay sequence section 7, or according to the sequence control in the relay sequence section 7, or the operating section 1. This configuration includes a display section 9 that displays a simulated plant state in response to a plant state setting signal from the plant state setting signal.

The calculation unit 1 includes a plant state setting device 11 for inputting a command for a desired simulated plant state;
a logic sequence unit 15 that performs calculations to control and output a simulated state of the plant to the simulation control till panel 3 in response to a command input from the control unit 5 or an operation signal input from the operation unit 5 via the digital input device 13; and,
It also has a plant state data table 17 that stores the calculation results in this logic sequence section 15. The calculation unit 1 further includes a data table 19 for storing and outputting data to be output to the relay sequence unit 7 for creating a simulated plant state according to the command input from the plant state setting device 11; This configuration includes a digital output device 21 that controls the output of data from the plant status data table 17 and the relay sequence output data table 19 to the relay sequence section 7 or the display section 9 as appropriate. In addition, in the calculation unit 1, the plant-like 8 setting device 11, the relay sequence output data table 19, and other components are as follows:
Due to its processing characteristics, each individual processing unit (CPU)
It consists of

Next, the operation of this embodiment will be explained using the processing flow shown in FIG.

First, when an initial condition command is input via the plant state setting device 11 to set the simulated plant state to a desired state (step 100), the logic sequence section 15 performs the following steps.
The initial condition data regarding the simulated plant state to be set according to the command input is read from the built-in initial condition data table D1, and based on this, the data to be output to the simulated control panel 3 is calculated and stored in the plant state data table 17. Good luck (steps 110 and 120). On the other hand, when a command is input, the plant state setting device 11 reads initial data for a relay sequence regarding a simulated plant state to be set according to the command input from the built-in initial data table D2 for relay detection. This is written into the relay sequence output data table 19 (step 210).

The digital output device 21 outputs the data written in the plant state data table 17 and the relay sequence output data table 19 to the display section 9'' of the simulation system [113] and the relay sequence section 7 at appropriate timing (step 130, 140, 220,
230).

The relay sequence unit 7 performs a sequence calculation based on the data supplied from the relay sequence output data table 19 via the digital output device 21, and outputs the calculation result to the display unit 9 (step 240).

The display unit 9 displays and outputs data according to the calculation results from the relay sequence unit 7 and the data supplied from the plant status data table 17 via the digital output device 21, so that the display unit 9 can display information from the plant status setting device 11 in the simulated control panel 3. A simulated plant state according to the setting command is output (step 250).

FIG. 4 shows a specific example of the relay sequence section 7 of the simulated control panel 3. In the figure, the relay sequence section 7 is connected in series to a reset switch 25 consisting of a normally closed contact that resets the range control to a positive terminal output line 23 of a power source (not shown), and is connected in series to the reset switch 25. An A state setting section 29 and a B state setting section 31 are connected in parallel to set the relay sequence to, for example, predetermined simulated A state and B state via an output contact 27 consisting of a normally closed contact whose operation is controlled by ing. This A state setting section 29 and B state setting section 31
is the output contact 27 and the negative terminal output 1i1 of the power supply
45, an A state setting switch 33 and an A state holding relay 35, and a B state setting switch 37 and a B state holding relay 39 are connected in series. Further, the A state setting section 29 and the B state setting section 31 are connected in parallel to the A state setting switch 33 and the B state setting switch 37, respectively, and their states are maintained by the A state holding relay 35 and the B state holding relay 39, respectively. It has an A state holding contact 41 and a BtL9 holding contact 43 which are normally closed contacts.

The operation when the relay sequence section 7 has the above-described configuration and inputs an initial condition command to the plant state setting device 11 in order to set the simulated control panel 3 to the A state, for example, will be described below.

The operation in the calculation section 1 when a command is input to the plant state setting device 11 is as described above, and in particular, the data table 19 for relay sequence output indicates that the relay sequence section 7 should be set to the A state after being reset. Command data has been written.

The calculation unit 1 first sets the A state setting unit by temporarily turning off the output contact 27 in order to reset the relay sequence according to the data written in the relay sequence output data table 19 via the digital output device 21. This is achieved by stopping the power supply to 29 and the B state setting unit 31. The calculation unit 1 temporarily turns on the A state setting switch 33 in order to set the relay sequence to the A state according to the next data in the relay sequence output data table 19. As a result, A of the relay sequence section 7
The state holding relay 35 is energized and sets the A state holding contact 41 to the on state, thereby maintaining the energized state even when the A state setting switch 33 returns to the off state, and repeating the relay sequence in a simulated A state. It keeps it in that state.

Note that this series of actions for setting the A state is the same when setting the B state.

It should be noted that the present invention is not limited to the above-mentioned embodiments, and can be modified in various ways. For example, by adding a function to the relay sequence output data table 17 to store the contents of the valve table for several hours, It is also possible to display on the simulated control panel 3 not only the plant state that is known in advance, but also the plant state at any time within the time that can be stored.

[Effects of the Invention] As explained above, according to the present invention, in a device that simulates the action of a controlled object according to a driving operation, processing of a relay sequence that partially takes charge of setting a simulated state of a controlled object is performed for setting a simulated state. Since this can be done automatically in response to the display, it is possible to reduce the effort required to simulate set the controlled object to a desired state without increasing the time required for setting the simulated state.
