Abstract

PURPOSE:To obtain the display method by which comparison between the displayed quantities and reading of variation in an atomic power plant and the like can be performed readily, by displaying many status quantities in parallel in a bar graph mode. CONSTITUTION:The process input signals from many process input devices 2a- 2n are read out at suitable periods and processed in a computer data processor part 3, which is provided with an A/D converter part, a memory, an operating part, and the like. Then the display data are obtained. Many status quantities of an atomic power plant and the like are displayed in parallel in a bar graph mode on a single scale board 1, where in CRT scales 1a and 1b are provided, through a display device 4. Therefore, the display method of multichannel quantities, in which the comparison of the display quantities and the reading of variation are easy, can be obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION In this invention, an instruction method C for specifying multi-channel amounts on the same tsubo surface is provided.

Conventional nuclear power generation plan) (Leave two, one instruction 1
One indicator was provided for each.

Therefore, even if the indicated quantities are mutually compared, they are mutually (
:1llf'l: Due to the location, the workability of operation and monitoring was poor. That is, according to this method of directing force I:
If the d14 Hanho was live, it would be easy to have a delay in TFC operation, and there was no room for operation, so there were many absences.

This invention is a 481-order system that eliminates the long-term problems of the conventional ones, as described above, and allows comparison between the indicated quantities by using a single indicator ≦: Indicating a large number of indicated quantities in parallel. It is an object of the present invention to provide an instruction method that allows easy reading of information indicated by a state of change.

An embodiment of the instruction method of the present invention will be described below. The figure is a block diagram of a monitoring device for a nuclear power plant. In the figure, reference numeral 1 denotes a school board made of a transparent plastic plate, on which scales 1a and 1b are printed on both left and right ends, and is used as a display unit on a cathode ray tube of a display device 4, which will be described next.

2a to 2n are an arbitrary number of n (%n=5 in this case) process input devices in total, which are composed of analog values and process input signals PII to 2n indicating the status of process devices (not shown).
Output PIn. 3 is the process input signal PII to PI
An analog/digital converter that converts n into a digital signal, reads the output of the analog/digital converter as data, performs predetermined arithmetic processing, and converts the analog/digital converter into a digital signal.
Control and management of digital conversion device and display device 4
A data processing unit 4 includes a computer and a memory for storing data necessary for the operation of the computer, and a data processing unit 4 inputs data and control signals output from the data processing unit and outputs data in the format shown on the scale plate 1. In other words, the state quantity A ''-1 corresponding to the pulse input signals PII to PInK
This is a display device that displays images, a so-called CRT device. A scale plate is installed on the cathode ray tube of the display device 4 so that the screen can be seen through the scale plate 1.

In operation, the data processing section 3 receives the process input signal P1
1=PIn is read at an appropriate cycle, processed by predetermined arithmetic processing, and multiplied by an appropriate coefficient, for example, to obtain display data. This display data is input to the display device 4 and displayed, ie, instructed, on the cathode ray tube in the form of a bar graph as shown in the figure. P2 If the amount of the process input signals PII to PIn changes due to a change in the state of the process device, the length of the bar that is displayed also changes in accordance with the change.

In the above embodiments, the reference target is the state quantity of a nuclear power plant, but it may be another state quantity, such as a steel plant.

As described above, according to the present invention, a large number of state quantities are displayed in a line in the form of bar graphs 27, so that plant operators can read the operating position and move away to read the operation position θ or change their line of sight. Since there is no need to read the state quantities, the burden on the operator in reading the state quantities is reduced.Therefore, reading errors and the inconvenience of inducing operational errors due to the complexity of reading can be avoided.
