Abstract

PURPOSE:To prevent previously a misoperation by supplying the operation signal to a deciding device from an operating tool and comparing the using conditions of the operating tool with the present state of a plant to deliver the operation signal to the plant when the coincidence is obtained from said comparison. CONSTITUTION:An operating tool is provided to a control panel 3, and the operating signal is supplied to a deciding device 4 from the operating tool. The device 4 decides whether or not the operating signal is appropriate to the present state of an atomic power plant 5 and delivers this signal to the plant 5 if it is proper to the state of the plant 5. The plant 5 undergoes the control of its operation with said operating signal and delivers the result of this control to the device 4 as a feedback signal. Then the operating state of the plant 5 is displayed on a CRT6. If the result of this decision is not appro priate, an alrm is given to an operator. At the same time, the plant state is estimated when the operating signal is supplied to the plant 5. The result of this estiamtion is also displayed on the CRT6.

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention provides a man-machine interface device that allows an operator to output operation signals to a plant by operating operating tools arranged on an operation panel to operate the plant. Regarding.

(Technical background of the invention and its problems) In general, in plants such as nuclear power plants, as shown in FIG. A man-machine interface device is used.

In such a man-machine interface device, the operating tool is covered with a cover to prevent the operator from accidentally erroneously operating the operating tool. In addition, some operating tools that have a large impact on the plant are designed so that they cannot be operated unless the key is inserted and the lock is released. , however, such a man-machine interface.

In the Ace device, operation signals from the operation and tools are input directly to the plant 2, so the operation is controlled. If the operator confidently performs an erroneous operation, such erroneous operations cannot be prevented by the above-mentioned erroneous operation prevention measures. In other words, if an operation that was performed with confidence turns out to be an error, in about 80% of cases, the operator will immediately determine that it was an error, and recovery operations will be performed, causing damage to plant equipment. Avoided. However,
The remaining 20% of erroneous operations go unnoticed by operators, so recovery operations are not performed and the plant
There is a risk of some kind of negative impact on the plant, such as damage to equipment.

(Object of the invention) This invention has been made in consideration of the above facts,
The object of the present invention is to provide a man-machine interface device that can prevent erroneous operation of operating tools and reduce damage to plant equipment and reduction in operating rate.

, (Summary of the Invention) In order to achieve the above object, the man-machine interface device according to the present invention operates a plant based on operation signals from an operator placed on an operation panel. Input the operation signal from the device into the determination device,
This judgment device compares the operating conditions of the operated operating tool with the current state of the plant, and when the two match, it outputs an operating signal to the plant, thereby preventing erroneous plant operations. This is to prevent

′('Example i of the invention)' Hereinafter, embodiments of this invention will be described based on the drawings.

FIG. 1 is a conceptual diagram showing an embodiment of a man-machine interface device according to the present invention.

The operation of the nuclear power generation plan +5 is controlled by this operation signal, and the result is output to the determination device 4 as a feedback signal. ,・,Judgment device! Based on this feedback signal, 4 causes the 1.5T/run I to the operating state 5 to be displayed on the negative 1-wire tube (hereinafter referred to as CRT) 6.・ ・ □ ・１
On the other hand, the determination device 4 receives the operation signal 1 from the operation tool.
If it is determined that the control signal is not appropriate for the current state of the plant, a second warning will be issued to the operator, and at the same time, the plant state will be predicted when the operation signal is input to the plant. It calculates 1 and displays the result on the CRT 6. 6, ・：
! 1.49 The functions of the fixed equipment W1 will be explained in detail based on FIG.

Ugly work*t? 1, for example, an arbitrary single pump activation signal λ is input to the determination device 4 and φ, and this operation signal is temporarily stored in the operation input stack 7.

Next, the usage conditions of the operating tool that transmitted this operating signal are compared with the current state of the plant. The conditions for using the operating tools are those listed in the technical specifications and operating procedure manuals, etc.
The current status of the plant is defined by various parameters of the current status of the nuclear power plant. When the operation tool usage conditions match the current state of the plant, the operation signal stored in the operation input stack 7 is output to the nuclear power plant 5.
- The operation of the nuclear power plant 5 is controlled by this operation signal, and the single pump specified by the operation signal is activated. Various parameters of the nuclear power plant 5 that have changed due to the activation of this pump are outputted to the determination device @4 as a feedback signal.

Judgment device i! ! 4 processes this feedback signal and outputs the changed nuclear power plant 5 to the operation signal.
The change status of is displayed on the C/RT6. 1. On the other hand, operator usage: If the conditions and various parameters of the current plant do not match, the judgment device 4 issues an alarm to the operator. At the same time, the judgment device 4 The system predicts and calculates the state of change in the nuclear power plant 5 assuming that the operation of the nuclear power plant 5 is controlled by operation signals input from the operating tools, and displays the results on the CRT 6.

If the predicted calculation result displayed on the CRT 6 is what the operator intended, a confirmation signal is output to the determination device 4. In the determination device 4, the operation signal stored in the operation input stack 7 is outputted to the nuclear power plant 5 in response to this confirmation signal. The output of the confirmation signal to the determination device 4 is as follows:
You can operate the touch panel installed on the CRT6 screen, or use a light pen instead of the touch panel to perform CR.
This is done by specifying the position on the TG, etc.

According to this embodiment, an operation signal from an operation tool arranged on the operation panel 1 is inputted to the determination device 4, and within this determination device 4, it is determined whether or not the operation signal is appropriate for the current state of the nuclear power plant 5. Therefore, even if the operator makes a mistake in the operation he or she is confident of, the operator can confirm the mistake.

Therefore, nuclear power generation plan h due to incorrect operation of operating tools
iz damage of No. 5 can be prevented, and a reduction in the operating rate of the nuclear power plant 5 can be reduced.

In the above embodiment C, the operation signal from the operation tool is, for example, a signal to start an arbitrary single pump, but the operation signal may be a signal for operating multiple devices, for example, an arbitrary signal. It may also be a signal for starting and stopping a plurality of pumps. In this case, a plurality of operation signals are stored in the operation input stack 7 of the determination device 4. Then, the conditions of use of the operating tool that transmitted each of the operating signals are compared with the current parameters of the nuclear power plant 5, and the suitability of each operating signal is determined. In this way, when a large number of different operation signals are input to the determination device 4 at the same time, the operability of the man-machine interface device can be improved.
