Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] This invention relates to the operation of a plant simulator.

(Prior Art) Conventionally, plant simulators have directly simulated the operation panel of an actual machine, and as many switches as there are to be operated are arranged on the operation panel.

FIG. 2 is an example of simulator input/output using a single operation panel. Reference numeral 10 is an operation panel, on which a switch 11, an indicator light 12,
Indicator instruments 13 are arranged, and traffic lights 11a,
It is connected to a simulator meter 20 through 12a and 13a, and is processed by a simulation program 21.

As many switches 11 as there are pumps and valves to be operated are attached to the operation panel.

When a start (or stop) operation is performed using the switch 11, the switch input signal 1 is used as a start signal.
It is input to the computer 20 from 1a. The simulation program 21 executes calculations based on the input signals. The indicator light 1 on the operation panel is transmitted through the execution result display signal line 12a and the instruction output signal line 13a.
2 and the indicator 13.

[Problem that the invention seeks to solve]

Since the conventional simulation operation panel is constructed as described above, it is necessary to provide as many switches as there are objects to be operated, and there is a limit to the miniaturization of the panel.

This invention was made to solve the above problems, and its purpose is to reduce the number of switches to be operated and reduce the overall size of the panel while displaying the plant status. do.

[Means for solving problems]

In the device according to the present invention, the object to be operated is represented by an illuminated pushbutton provided on the equipment part represented by a simulated system diagram on the control panel surface, and the device can start the auxiliary equipment, start the auxiliary equipment,
One switch or several switches depending on the model are provided for stopping, opening, and closing operations, and the selected one is an illuminated push button switch.
It is designed so that it can be operated using a nearby control switch.

[Effect]

The illuminated pushbutton switch in this invention includes:
It is arranged in the simulated system diagram displayed on the operation panel representing the simulated system, and is formed by a small push button, and the operator specifies which auxiliary equipment it is by pushing the push button switch. When designated, the illumination section will flicker and the auxiliary equipment will be operated using the operating switch at hand. Once the operation is complete, the flicker will stop and display the operating status of its auxiliary equipment.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to FIG. In FIG. 1, 10 is an operation panel, 11 is an illuminated pushbutton switch, 11-1 and 11-2 are switch parts, 12-1 and 12-2 are illumination lamps, 14 is an operation switch, and 20 is an illuminated push button switch. Simulation computer; 21 is a simulation program; 22-1 and 22-2 are memories for storing pushbutton switch input signals; 23-1 and 23-2 are flicker signal generators; 24-1 and 24-2 teeth
AND operator, 25-1, 25-2 are valve models,
26-1 and 26-2 are OR calculation machines. Next, its operation will be explained.

In front of the operation panel 10, the operator selects the valve to be operated by pressing down the push button switch 11. Suppose now that valve 11-1 is selected. The signal from this switch 11-1 is input to the simulation program 21 of the simulation computer 20. And memory 2
Set 2-1. When this memory 22-1 is set, the flicker signal generator 23-1 outputs a flicker signal according to its output signal, and the OR
Illumination lamp 1 from the computer through the computer 26-1
2-1. For this reason, the illumination lamp 12
-1 flickers. This flickering allows the operator to confirm the selected valve on the mirror.

In this state, when the operator operates the operation switch 14, this signal is input to the simulation program 21 and stored in the selection memory 22-1.
AND operation signal 2 is applied to the selected valve model 25-1 only by AND processing with the AND operator 24-1.
4-1a is issued.

This operation signal 24-1a causes the valve model 25
-1 executes simulation processing. As a result of the execution, the memory 22-1 is reset, and at the same time, the state of the valve is changed to the OR operator 26-1.
Output through 1. This signal lights up the indicator light 12-1 on the operation panel.

If the operator selects the valve 11-2, it can be operated from the valve operating switch 14 in the same manner as described above.

In this way, only the valves selected by the operator can be operated with a single operating switch at hand.

Although this example shows two valves,
Needless to say, the same effect can be obtained regardless of the number of valves. In addition to valves, pumps,
It can be applied to anything that can be operated from the control panel, such as burners and disconnectors.

〔Effect of the invention〕

As described above, according to the present invention, the simulator operation panel can be made extremely compact because the operation switch, which used to be one for each operation target, is now composed of a small push button switch and an operation switch for representative operation. In addition, the simulated system diagram displayed on the control panel and illuminated pushbutton switches allow you to understand the system and operate it while checking the equipment you are trying to operate, making it a highly effective simulator for learning and training. can get.
