Abstract

PURPOSE:To display time series change of a measuring signal for a long time without reducing resolution by dividing and setting up a time axis of a display screen of a CRT display device into two parts or more having different resolution. CONSTITUTION:A device consisting of an electronic computer 2, a storage device 3 and a CRT display 4 is constituted so that a characteristic curve 7 indicating the time change of a measuring signal is obtained at fine resolution in the time axis 5 having fine resolution and a characteristic curve 9 indicating the time change of measuring signal is obtained at rough resolution in the time axis 8 having rough resolution. Consequently, time series change can be simultaneously measured by fine and rough resolution during the period from the current time to time T0 and before T0, respectively.

In the figure, 1 is a measurement signal, 2 is an electronic computer to which the measurement signal 1 is input, 3 is a storage device, and 4 is a CRT display device that displays temporal changes in the measurement signal 1. Conventionally, an example of a display screen of a CRT display device in this type of measurement signal display device is shown in FIG. In Fig. 2, numeral 5 is a time axis with evenly spaced scales and fine resolution, and numeral 6 is a coordinate axis representing an engineering unit or a certain normalized physical quantity. A characteristic curve (trend graph) 7 is clearly displayed. The position of the current time on the time axis 5 is usually the rightmost edge, and the characteristic curve 7 moves to the left as time passes, always at the time T up to the past on the time axis 5.

The time axis of the display screen of the "R'l" display device is divided into a fine-resolution part and a coarse-resolution part, and for past time periods closer to the present, detailed changes are displayed with the resolution of the fine part, and the change state is displayed at a certain level. Our goal is to provide a measurement signal display device that can also display rough changes over a long period of time with the resolution of the above-mentioned coarse portions in past time periods that are far away from the current time.
