Description

[Detailed Description of the Invention] When operating a control device of a BWR nuclear power plant or the like, the present invention utilizes the operator's call at the time of operation to confirm that the call and the operation signal match. , relates to an operation confirmation device that provides an operation signal to an actual process.

In conventional nuclear power plant operations, operators call out the object to be operated before performing the operation, but if an operator is careless and operates a controller that is not intended for operation, the system detects the erroneous operation. had the disadvantage that it could not be detected unless the process became abnormal.

Conventional control devices are lacking. The purpose is to improve the operational reliability of the plant by checking operator operations.

When operating a control device of a nuclear power plant or the like, the present invention allows an operator to input the operation target by voice before operation, thereby making it possible to compare the actual operation signal with the voice input. When the operation target and the actual operation signal do not match, 1. Notify the operator of the erroneous operation; 2. Prohibit the operation signal to prevent the control device from operating due to erroneous operation.

Examples of the present invention are shown in FIGS. 1 and 2 below.

In a nuclear power plant, when an operator operates the control device 1, the operator always calls out the operation name before operating the control device 1.

This operation name is determined by the voice recognition device 2, and this determination signal 3 is output to the operation confirmation section 4. After calling out the operation name, the operator operates the operation device 6 on the control panel 5, and the operation signal 7 is output from the operation device 6.

In the embodiment shown in FIG. 1, the operation signal 7 from the operation device 6 is output to the control device 1 as well as to the operation confirmation section 4. In the operation confirmation unit 4, the determination signal 3 and the operation signal 7
are compared, and if the signals do not match, a trigger signal 9 is output to the display device 8, and an erroneous operation is displayed on the display device 8.

In the embodiment of FIG. 2, the operation signal 7 from the operation device 6 is
It is not output directly to the control device 1, but only to the operation confirmation section 11. In the operation confirmation section 11, the discrimination signal 3 and the operation signal 7 are compared, and if the signals do not match, the output of the control signal 10 to the control device 1 is blocked. At the same time, a trigger signal 9 is output to the display device 8 to display an erroneous operation on the display device 8.

The configuration of the operation confirmation parts 4 and 11 in Figures 1 and 2 is shown in Figure 3.
It is shown in Fig. 4.

The operation confirmation units 4 and 11 are composed of arithmetic units Pi, P2 and P3, and memos IJMI and M2. The arithmetic device P1 calls the operation number corresponding to the discrimination signal 3 from the memory lJM,1, and outputs it to the arithmetic device P3.

The arithmetic device P2 reads the operation number corresponding to the operation signal 7 from each of the manipulators from the memo IJ M 2 and outputs it to the arithmetic device P3. The arithmetic device P3 is the arithmetic device Pi, P
Compare the input signals (operation numbers) from 2. Since the output of the comparison results differs between the embodiments shown in FIGS. 1 and 2, they are shown separately in FIGS. 3 and 4.

In FIG. 3, the comparison result in the arithmetic device P3 outputs a trigger signal 9 to the display device 8 to display an erroneous operation only when the operation numbers do not match.

In FIG. 4, the comparison result in the arithmetic device P3 is not only the trigger signal output to the display device 8, but also the trigger signal output from the arithmetic device P3 if the operation numbers used to block the output of the operation signal 7 do not match. 9 prevents the output of the operation signal 7.

If the operation numbers match, a trigger signal 9 is sent from the calculation device P3.
is not output, the operation signal 7 is output to the control device 1. In addition, in consideration of malfunction of the arithmetic unit, etc., a bypass signal 12 is provided for the operator to bypass the trigger signal.

The time limit element 14 is a signal 13 determined by comparison with the operation signal 7.
Established for time coordination. Namely.

This is intended to cause the output of the operation signal to the process to be output when the matching with the call signal is completed.

In FIGS. 3 and 4, when there is no signal from the arithmetic device P1, the arithmetic device P3 does not output a trigger signal.

According to the present invention, by comparing the operation name called by the operator with the operation signal, it is shown whether the actual operation is what the operator intended, and in the case of an erroneous operation, the control signal is blocked. This is effective in preventing plant abnormalities caused by operator errors.
