Detailed Description of the Invention

[Object of the Invention]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a driving training simulator (hereinafter referred to as simulator device).

[0002]

2. Description of the Related Art Conventionally, simulators used for plant operation training in industries such as electric power, chemicals, and steel manufacturing obtain process quantities by solving physical equations according to the operation contents of trainees to determine plant behavior. Is simulated.

An example of a conventional simple simulator device will be described with reference to FIG. When conducting driving training, the trainee first selects the desired training content by touching the touch screen 1a from the training content displayed on the CRT display 1 having the input device shown in FIG. The selected training content is input to the plant state setting unit 3 via the operation content input unit 2.

According to the selected training content, the plant state setting unit 3 calculates the state of auxiliary machines such as pumps, valves, fans, etc., which are stored in advance, and the plant state consisting of process quantities of the plant such as temperature, pressure and flow rate. It is set in the control unit 4.
In the arithmetic and control unit 4, the initialization is performed according to the contents of the set plant state, and the contents of the initialized state of the auxiliary machine and the process amount of the plant are displayed on the CRT display 1 via the display output unit 5. It is displayed in the plant system diagram.

Next, the trainee operates the valves, pumps and the like displayed on the plant system diagram by touching them on the touch screen 1a. The touch screen 1a outputs to the operation content input unit 2 an operation signal S1 indicating the operation content performed by the trainee, for example, valve opening / closing, pump start / stop, and the like. The operation content input unit 2 inputs the operation signal S1 and outputs the operation signal S1 to the arithmetic control unit 4.

Based on the operation signal S1 and the contents of the plant state preset by the plant state setting unit 3, the arithmetic control unit 4 uses a physical formula to simulate the process amount of the plant such as temperature, pressure and flow rate. To do. The result of this simulation calculation is output from the calculation control unit 4 to the display output unit 5, and the display output unit 5 displays the result of this simulation calculation as the simulation result signal S2.
Is output to the CRT display 1.

The CRT display 1 displays the simulation calculation result by the simulation result signal S2. At this time, opening and closing of valves, pumps, etc. that changed according to the contents of operations performed by trainees,
The operating state such as start / stop is also displayed on the CRT display 1 at the same time.

[0008]

However, in such a conventional simulator device, when simulating a plant state having a complicated plant characteristic, a complicated physical expression expressing the complicated plant characteristic is solved in a short time. Can be difficult.

Usually, in such a case, a method of simulating a plant state by obtaining a solution using an approximate expression is adopted. However, for example, a power plant using a gas having a non-linear characteristic has a poor plant dynamic characteristic. When simulating a stable plant state, this method cannot be used because the parameters of the approximate expression change irregularly.

On the other hand, many trainees who use the simulator device are beginners, and the purpose of use of the simulator device by this beginner trainer is not to learn the dynamic characteristics to see how the plant quantity of the plant changes, but to operate it. In most cases, learning the operating procedures is the main subject. Further, in the case of learning this operating procedure, unlike in the case of learning the dynamic characteristics, it is sufficient to judge whether or not the operating procedure is correct, and it is not always necessary to simulate the plant state using a physical formula. ..

An object of the present invention is to provide an operation training simulator capable of improving the training effect by selecting a plant state simulation method according to the purpose of use.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram of a simulator device according to an embodiment of the present invention. In the figure, the same symbols as those in FIG. 5 indicate the same or corresponding portions. The plant mode determination unit 6 stores the state of the auxiliary machine and the process amount of the plant in the plant state whose main purpose is to learn the dynamic characteristics.

The plant mode determination unit 6 compares the stored auxiliary machine state and plant process amount with the stored auxiliary machine state and plant process amount in the plant state set by the plant state setting unit 3. To do.

In this way, it is determined whether the purpose of use of the simulator device is mainly to learn driving procedures or to learn plant dynamic characteristics, and by this determination, the set plant state is simulated. As a method for doing so, one of the driving operation mode for updating the result screen or the dynamic characteristic calculation mode simulated by using a physical formula is selected.

Further, the plant mode judging section 6 inputs the judgment result into the operation content input section 2 to
The operation signal S1 is input to either the arithmetic control unit 4 or the operation content evaluation unit 7 described later. Furthermore, the simulation calculation result of the calculation control unit 4 and the operation result screen selected by the next screen selection unit 8 described later are output to the display output unit 5.

The standard operating procedure storage unit 9 is a standard operating procedure for operating auxiliary equipment such as opening / closing of valves, starting / stopping pumps, etc., which is performed in sequence at plant startup, and for operating auxiliary equipment after plant startup. Is stored in advance. The operation content evaluation unit 7 compares and evaluates the operation signal S1 input by the operation content input unit 2 with the standard operation procedure of the auxiliary machine stored in the standard operation procedure storage unit 9.

The operation result screen storage unit 10 stores the operation result screen of the plant state when the auxiliary machinery is operated correctly. When the operation content evaluation unit 7 evaluates that the operation content is correct, the next screen selection unit 8 is operated until the CRT display 1
The screen to be displayed next is selected from the operation result screen storage unit 10 instead of the screen displayed on the screen.

Next, the simulation operation of the simulator device thus constructed will be described.

The trainee can use the CRT display 1 according to the training content.
The desired training content is selected from the training content displayed on the touch screen 1a by touching it. The selected training content is input to the plant state setting unit 3 from the touch screen 1a via the operation content input unit 2.

The plant state setting unit 3 inputs the stored plant state to the plant mode determination unit 6 and the operation content evaluation unit 7 according to the selected training content, and sets this plant state in the arithmetic control unit 4. Then, the arithmetic control unit 4 is initialized.

The plant mode determination unit 6 is a state of the auxiliary machine in the plant state whose main purpose is to learn the dynamic characteristics stored in advance and the process amount of the plant, and the auxiliary machine in the plant state set by the plant state setting unit 3. And the process amount are compared, and it is determined whether the selected training content is mainly for learning the operation procedure or for learning the plant dynamic characteristics.

Here, when the plant mode determination unit 6 determines that the selected training content is mainly for learning the plant dynamic characteristics, the plant state is simulated by the dynamic characteristic calculation mode. ..

In this case, the plant mode judging unit 6 makes the contents of the arithmetic control unit 4 initialized according to the selected training contents based on the judgment, through the display unit output unit 5 the CRT.
The contents are output to the display unit 1, and the CRT display unit 1 displays the contents as a plant system diagram.

After that, when the trainee operates the auxiliary equipment of the plant system diagram by touching the touch screen 1a,
The operation signal S1 is input to the arithmetic control unit 4 via the operation content input unit 2 according to the determination of the plant mode determination unit 6.

In the arithmetic control unit 4, the process amount is simulated by a physical formula according to the operation signal S1. The plant mode determination unit 6 transmits the simulation calculation result obtained by the calculation control unit 4 to the display output unit 5 and outputs it to the CRT display 1. C
The RT display 1 displays the simulation calculation result to the trainee by the simulation result signal S2.

On the other hand, in the plant mode judging section 6,
When it is determined that the selected training content is mainly for learning the operation procedure, the plant state is simulated by the operation mode.

In this operation mode, the plant state is determined only by the change in the state of the auxiliary machine without performing the simulation calculation of the process amount by the physical formula. Therefore, the operation content evaluation unit 7 first determines which plant state the set plant state is based on the state of the auxiliary machine according to the standard operation procedure stored in the standard operation procedure storage unit 9. Then, a screen corresponding to the plant state thus obtained is selected from the operation result screen storage unit 10 by the next screen selection unit 8 and displayed on the CRT display 1 as a plant system diagram.

After that, every time the trainee performs one operation of touching the valve, pump, etc. of the CRT display 1, the operation signal S1 passes through the operation content input section 2 according to the determination of the plant mode determination section 6 and the operation content. It is input to the evaluation unit 7. In the operation content evaluation unit 7, the operation signal S1 and the standard operation procedure storage unit 9
The standard operation procedure in this plant state stored in the table is compared to determine whether the operation is a correct operation.

If the operation is correct, the next screen selecting section 8 is instructed to display the screen resulting from the operation. In the next screen selection unit 8, in accordance with the instruction from the operation content evaluation unit 7, a screen showing the result of the correct operation is selected from the operation result screens stored in the operation result screen storage unit 10. Then, this screen is output to the CRT display 1 via the plant mode determination unit 6 and the display output unit 5, and the operation result is automatically displayed every time the trainee performs one operation.

Next, the simulation operation of the above-described simple type operation training simulation apparatus will be described by taking a power plant using gas as an example.

In the case of a power plant using gas, the gas characteristic is often a non-linear characteristic, and is greatly influenced by disturbance (environmental environmental conditions). When this is solved by a physical formula, it becomes a huge number of formulas, and it is difficult to solve this in a short time by an electronic computer for a simulator. For example, when activating this power plant, the trainee operates according to the content of the activation chart shown in FIG.

In this case, looking at the contents of this starting chart from the importance of the training, as shown in FIG. 2 (2), before starting the load increase, the starting operation procedure of each gas system equipment is mainly learned, After the load rises, the behavior of the plant, that is, the learning of dynamic characteristics will be the main focus. In addition, as shown in FIG.
Before the load rises, it becomes difficult to calculate the dynamic characteristics using a physical formula.

At the beginning of the training, the trainee trains the CRT.
If the desired training content is selected from the training content displayed on the display unit 1, the selected training content is input to the plant state setting unit 3 via the operation content input unit 2.
The plant state setting unit 3 sets the plant state according to the selected training content, and the plant mode determination unit 6 determines the mode of this plant state.

Here, the mode determination operation in the plant mode determination unit 6 will be described with reference to the flowchart shown in FIG. When the plant state set by the plant state setting unit 3 is input to the plant mode determination unit 6 (process 21), the plant mode determination unit 6 mainly increases the load of the plant, which is mainly acquired by the dynamic characteristics stored in advance. The state of the auxiliary machine (D1, D2, ..., Dn) in the state is compared with the state of the auxiliary machine in the plant state (D1 ', D2', ..., Dn ') input by the plant state setting unit 3 ( Judgment 22).

As a result of this comparison, if the states of the auxiliary machines are all the same (Y at decision 22), the process amount decision criterion stored in the plant mode decision unit 6 indicating the load increase state is further stored. (A1, A2, ..., Am) and the input plant state process quantities (A1 ′, A2 ′, ..., A)
m ') is compared (decision 23).

As a result of this comparison, if all the process quantities exceed the standard (Y in judgment 23), the set plant state is judged to be the load increase or the plant condition after the load increase, and simulated by the dynamic characteristic mode. Select the method to do.

Further, if there is at least one that does not hold in the comparison of the states of the auxiliary machines and the determination of the process amount (determination 22, 2)
3 N), it is determined that the load has not yet risen, and it is determined that the simulation is performed according to the driving operation mode.

As described above, the plant mode determination unit 6
When the operation mode is selected, the operation content evaluation unit 7 stores the auxiliary machine state in the plant state set by the plant state setting unit 3 and the standard operation procedure storage unit 9 in the operation content evaluation unit 7. By comparing with the state of the auxiliary equipment according to the standard operation procedure, it is possible to judge which state the plant state is.

Next, the operation content determination operation in the operation content evaluation unit 7 will be described with reference to the flowchart shown in FIG. The operation content evaluation unit 7 compares the input state of the auxiliary machinery with the standard operating procedure of the auxiliary machinery stored in the standard operating procedure storage unit 9 in sequence from the pre-plant start state. (Process 31) If the input state of the predetermined auxiliary machine in the plant state matches the standard operating procedure (Y in decision 32), the states of the other auxiliary machines are compared with the standard operating procedure to make a difference. Until it becomes an item (decision 32
N) Make this comparison. Then, the state of the different auxiliary equipment is determined to be the present plant state, and this plant state is displayed on the CRT display 1.

Thereafter, when the trainee operates the auxiliary machine by touching the touch screen 1a, the operation signal S1 is input to the operation content evaluation section 7. The operation content evaluation unit 7 selects the operation of the S-th auxiliary equipment, which is the next operation, from the standard operation procedure stored in the standard operation procedure storage unit 9 from the plant state up to now. By comparing this item with the operation signal S1, it is determined whether or not the operation by the operator is correct.

When it is judged that the operation by the operator is correct (Y in judgment 33), the next screen when the correct operation stored in the operation result screen storage section 10 is performed to the next screen selection section 8 is performed. It is instructed to select the operation result screen indicating the plant state (process 34). As a result, the operation result is automatically displayed. When it is determined that the operation of the operator is not correct (N in decision 33), the screen does not change.

The next screen selection unit 8 selects a screen showing the result of a correct operation from the operation result screens stored in the operation result screen storage unit 10 according to the instruction from the operation content evaluation unit 7. Then, this screen is output to the CRT display 1 via the plant mode determination unit 6 and the display output unit 5, and the operation result is automatically displayed every time the trainee performs one operation.

As described above, it is possible to select whether the simulation method is the operation mode or the dynamic characteristic calculation mode from the set plant state. When the operation mode is selected, the physical formula is used. Instead, the plant state can be simulated by changing the display screen each time the auxiliary machine is operated.

In the above description, when the operation content evaluation unit 7 determines that the operation of the trainee is not correct, the screen does not change. However, the operation result screen storage unit 10 stores an erroneous operation message. Every time, operation content evaluation unit 7
When it is determined that the operation of the trainee is not correct, the operation error signal may be sent to the next screen selection unit 8 to display the operation error message.

[0048]

As described above, according to the present invention, whether the purpose of use of the simulator device from the set plant state is to mainly learn the operation procedure or to learn the plant dynamic characteristics. Can be determined. In addition, when learning the operation procedure is the main method, the method of simulating the plant state is not a method of finding a solution using a physical formula, but a simulation of updating the result screen of the CRT display if the correct operation procedure is performed. Can be a method. As a result, it is possible to carry out training according to the purpose of use of the simulator device, and to improve the training effect.
