Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to an input device using a touch screen, and particularly to an input device created to be suitable for operation of plant equipment.

[Background of the invention]

A touch screen is a device that detects the coordinates of the pressed point when you press a transparent plate attached to a CRT screen with your finger.It is used in combination with 9, CB, and T, and is already on the market. There is. There are various methods for detecting the coordinates of the pressed point.

For example, as shown in Figure 12, rectangular transparent electrodes are combined in vertical and horizontal directions, and an air gap is provided between them to prevent short circuits, and only the x and y coordinates of the pressed point are electrically connected. It is.

In addition to the above-mentioned method of pressing the transparent plate with your finger to enter a specified input,
Methods for specifying and inputting intangible aspects have also been developed. This technique is described in the U.S. Bibliography Datamation article “
Touchscreens: Pig Deal or Deal? ” for details. Considering these known technologies, the term "touch screen" used in the past is not necessarily limited to those that are touched or pressed, but broadly refers to "the coordinates (or It means "means for outputting information displayed by the coordinates".

When this is attached to the screen of a CRT, the screen is divided as shown in FIG. 13, and when, for example, D3 is pressed, the electrodes and the electrodes become conductive as shown in FIGS. 12 and 13. In addition to this, there is a method in which light emitting diodes and light receiving elements are arranged in the x and y directions and detects when the light beam at the pressed point is blocked, and a method that detects changes in the capacitance at the pressed point. , a conventional plant simulator will be explained with reference to FIG. The data necessary for calculation is installed in the card reader 31, and the data is transferred to the central processing unit (
(hereinafter abbreviated as CPU) 34, and necessary data files and processing programs are stored on a disk 35. Input data and processing results are printed by a line printer 32. The above-mentioned equipment is necessary before creating the calculation program, but the created calculation program simulates the dynamic characteristics of the plant, and further equipment necessary for plant simulation is added. That is, the setting device 37 is attached to the simulated control panel 37 that is actually operated by the operator.

362, an indicator 373, a recorder 374, and a digital output device 3 that are driven via an analog output device 363 based on the calculation result of the calculation program in the CPU 34.
It is composed of an annunciator 375 and a lamp 376 which are outputted via 64.

Conventionally, in plant simulation, there have been several methods for inputting plant operations into a computer depending on the purpose. In other words, Plant Simini V for operator training
-For evening, Magazine Thermal and Nuclear Power Generation, Volume 35, No. 5 (1)
984) p15 @ New central control panel Nuclear power plant and operation training by Simini V-Yu” etc.
An operation panel equivalent to the actual machine (simulation target) will be created and input/output processing will be performed using this. Taking nuclear power plants as an example, there were only two plant simulators in Japan that could conduct operation training: the BWR Operator Training Center for BWRs and the Nuclear Power Training Center for PWRs. While it is desirable for such devices to be constructed at low cost, it is necessary to simulate plant behavior in real time in response to operator operations online.

For this reason, these devices use, for example, five CRTs and a small, simplified operation panel. Even with this method, it is possible to display a considerable number of plant parameters (more than 600), and the number of indicators and recorders increases. Although it can be used as a substitute, there is a limit to the number of operation switches that can be simulated, and there remains a problem in standardizing the software without depending on the plant.

The above-mentioned problem is not limited to plant simulators, but can be widely applied to plant operations in general, and is an input method to a computer that results in the problem of efficiently realizing a wide variety of operation functions with a compact device. A system that combines a touch screen device and a CRT has been attracting attention in recent years. For example, the magazine Datamation 198 1 Touch Screens introduces touch screens. However, the technology disclosed in these publications uses a touch screen as an input device for a general-purpose computer, and does not address the purpose, configuration, function, or effect of problems specific to plant equipment operation. .

[Purpose of the invention]

The present invention has been made in view of the above-mentioned circumstances, and is equipped with a large number of switch functions and display functions for operating a plant, and is particularly suitable for plant operation, has no risk of erroneous operation, and has a wide range of operation range. The present invention aims to provide a touch screen type input device that is easy to modify, is small, lightweight, and inexpensive.

[Summary of the invention]

To further summarize and briefly outline the gist of the device of the present invention created to achieve the above object, the process input device 36 and the simulated operation panel 371CRT and Replace with touch panel and processing program. In detail, it includes a touch screen that detects a specified position on an instruction screen attached to the screen of a CRT surface water device and an XCRT display device, and a touch screen control device that inputs a detection signal of the position to a calculator. In a man-machine processing system, the CRT displays on its screen the system of the plant to be controlled. Further, the touch screen is characterized in that it has a function of instructing the equipment to be operated and its operating state by touching the equipment of the system.

[Embodiments of the invention]

FIG. 1 is a schematic system diagram of an embodiment of an input device according to the present invention.

In this embodiment, the simulated operation panel 37 and process input/output device 36 in the conventional example are replaced with two CRTs and a touch screen.

That is, the plant state quantity calculated by the CPU 34 is C
Via the RT display control device 12.22, CRTI, 2 (
11, 21). Operations from the operator are sent to the CPU 34 via the touch screen 13.23 and the Shitarachi screen control device 14.24. The details are described below.

In the conventional system, as for the simulated results of the plant state, analog state quantities have been presented as information using an indicator 373 or a recorder 374. In this example, the instantaneous value is displayed on the numerical display or par chart display shown in Figs. 2 to 4, and the
The elapsed value is presented on the /nd display. If records are required, they can be made in hard copy 15.25. Furthermore, the alarm screen shown in FIG. 6 can be used as an annunciator for 50s.

Below is an explanation of each screen and details of how to operate Simini V-Yu. The present embodiment is a nuclear power plant, Simini V-YU, and FIG. 2 is a CRT screen showing the overall configuration of the plant. If the operator wants to know the detailed operating status or perform operation on a particular system, he or she touches the box for that system shown at the bottom of the figure. For example, if you want to know the detailed operating status of the engineering safety system and perform operation operations in order to carry out simulation training in the event of an accident occurring in a nuclear reactor, if you touch the box for ``Construction cost system'', the screen shown in Figure 3 will appear. The screen shown in FIG. 2 is displayed on the CRT instead of the screen shown in FIG.

This screen is for monitoring the operating status of the engineering safety system, and the CRTC is activated from the screen.
It can be seen that the flow rate of H is flowing into the reactor pressure vessel. On the other hand, water was not injected into the reactor pressure vessel from HPC8 and LPC8. The operator also activates the HPCI, so
If you touch "PO2" at the bottom of the first operation system on the right side of the screen, the screen shown in Figure 4 will be displayed.The system consists of three pumps and one pump, and all valves are fully closed. situation,
The pump is in a stopped state, and all display colors are green. The operator turned on valves 1 and 9 to take the water source from the condensate tank.
After touching 21 and confirming that the relevant part flickers green, touch 6" at the bottom. The relevant X-Y coordinates are input via the Shitarachi screen input control device 14, and the CPU 34 controls the valve. The opening command for (1) is simulated, and when valve 1 is fully opened, the display color of valve (1) on the screen changes to red via the display control program CRT display control device 12. Next, the HPC8 pump 924 is started. If you touch the relevant part of the screen, a green flicker will appear, and if you touch ``1 Activation'' at the bottom of the screen, the activation of the HPCS pump 922 will be simulated in the CPU 34 according to the same procedure as described above, and as a result, the display color will become red. As a result, the pump discharge pressure was also high, and the valve confirmed that 1 pressure OK 4" on the screen was changed to 1 pressure cuff 6 KIl". Fully open valve (3) 933 using the same procedure as above, and open the condensate pump. Perform simulation calculations to inject water into a pressure vessel. As a result, 1 flow rate OT/H" on the same screen changes to 1 flow rate 1.800 T/H", and normal operation of HFO2 is confirmed, so the operation procedure ends. If you want to refer to the reactor water level and pressure, which are the main parameters related to the safety of the reactor during this period, touch the 1 to V mode section at the bottom of the screen and the screen shown in Figure 5 will be displayed. The water level will drop once, but HF
Activation of O2 indicates that there is a tendency for recovery. In addition, the screen shown in FIG. 6 is used as an expense report screen generated during normal operation. Furthermore, the screen shown in FIG. 7 is provided for operations on devices not shown in the system diagram.

For example, the activation air extractor activation status is shown to its right and is currently activated. If you want to interlock stop this, first touch the left end &2, and the lower operation switch display section will display the selectable states of the switch, i.e. 1 interlock stop, ``L alone,'' ``interlock start'', and 1 interlock stop.'' When you touch the button, a synchronized stop of the equipment is simulated.The screen shown in Figure 8 is prepared for setting the controller.Currently, the flow rate of the RCIC is set to 14.
5 T/H, the actual flow rate is 140 T/H. To increase this, first touch 41, R,
When the touch related to CIC is valid, if you press "increase", the set value will increase for that period, and when you release your hand, the set value will stop in that state. If you want to decrease it, you can do so by pressing 1 "Decrement".The controller then controls the actual flow rate to the set value.The above is for automatic mode, but if you touch 1 "Manual" Switch to manual mode and directly operate the flow control valve by increasing/decreasing operation to control the opening degree.

FIG. 9 shows the software configuration of this embodiment. The input signal from the touch screen control device 14.24 is input to the input processing section 34.
At 1,342, the meaning is analyzed from the X-Y coordinates and the type of CRT screen being displayed.

In the case of a display screen change, the display is changed to that screen, and in the case of an operation request, the finger processing request, such as opening a valve, starting a pump, increasing or decreasing a set value, etc., is set in the operation database 343. The plant simulation unit 344 calculates the plant state that is desired as the content of the operation database 343, and writes, for example, reactor water level, reactor pressure, etc. into the plant database 345. Based on these data, the display processing unit 346 attaches data corresponding to the screen requested to be displayed and outputs it to the CRT display control device 12.22.

FIG. 10 shows another implementation of the invention. In this embodiment, the operating status of a nuclear power generation plant 8 is monitored, and when an abnormality or accident occurs, an engineered safety facility 9 is activated based on the operator's judgment.

The figure is considerably simplified for convenience of explanation.

The states of the reactor system 81 and the turbine system 8z are input to the central processing unit 6 by the process input/output device 74, and their operating states are displayed on the CRT display control unit f, 1. 2 (33, 34
) and displayed on CRTI, 2 (31°32). An example of the clothing is shown in Figure 4. When an abnormality or accident occurs in a nuclear reactor, it may not be enough to simply shut down the reactor (scram), and operators may need to

In this embodiment, the touch screen 1 is used to activate the touch screen 1 for this purpose. The touch screen shown in FIG. 1 is used, and the resolution is 6 in the X direction and 5 in the Y axis direction. The lower part of the entire plant screen in Figure 2 is used for screen selection, and when you press "Princess display screen n1!" on touch screen 1, the screen shown in Figure 3 is displayed on the CRTI (31). The operation procedure is the same as that described in the previous embodiment, except that instead of the operation result being reflected in the arithmetic processing of the machine, actual plant equipment is operated.

FIG. 11 shows the software processing configuration of this embodiment. Input signals from the touch screen input control device 1 are periodically input to the input processing section (1), 61, and when a touch is detected, Output the X-Y coordinates. Operation processing unit 63
Based on the X-Y coordinates and the type of screen being displayed, if the display screen is to be changed, a screen change request is made to the display processing section (1), and if it is a device operation, the process is sent via the output processing section 64t-. It outputs valve opening/closing commands, pump start/stop commands, etc. to the output device 74.

In each of the above-described embodiments, the CRT and touch screen are used to display the plant system and perform switch functions, so a large number of switches can be displayed using compact components, and there is little risk of erroneous operation.

Furthermore, the manufacturing cost is relatively low compared to its multifunctionality.
