DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paperless recorder using a two-dimensional display, and more particularly to an improvement in a display screen.

[0002]

2. Description of the Related Art Recorders have conventionally used various physical quantities such as temperature, pressure, and gas components in various fields such as temperature history management of a heating / cooling process, monitoring of an operating state of a generator turbine, and meteorological measurement. Widely used as a device that converts voltage and current into electrical signals with a measurement sensor suitable for the measurement target, and records the state of change of these converted electrical signals over time as a line segment change on recording paper Have been.

[0003] However, such a conventional recorder,
Although each component block is digitally controlled by a microprocessor, it is configured to record on a recording paper a change waveform of a measurement signal and character data related to a measurement condition.

That is, the conventional recorder requires moving mechanism parts such as a recording pen, a servo mechanism, and a recording paper feed mechanism, and has a problem that the configuration is complicated. Another problem is that high-performance parts and materials must be used to prevent the recording operation from becoming unstable due to a change with time such as wear of these mechanical components. Further, when the consumables such as the recording pen and the recording paper are exhausted, the recording is interrupted, and the continuous measurement performance is deteriorated. In addition, there is a problem that man-hours and costs are generated due to supplementary maintenance and replacement of these consumables. Further, when it is desired to process the measurement result by computer, the recording result on the recording paper must be read and input again as digital data, which is not practical.

In order to solve these problems, a paperless recorder using a two-dimensional display instead of a recording paper as disclosed in, for example, Japanese Patent Laid-Open No. 10-253401 has been put to practical use. . This is configured so that a two-dimensional display such as a liquid crystal display is regarded as a recording paper and the change state of the measurement signal is graphically displayed, and conceptually, the measurement signal is digitized and stored in a memory. And the measurement data stored in the memory is read out, and the state of the change with the passage of the measurement time is graphically scroll-displayed on the two-dimensional display.

More specifically, measurement signals of a plurality of measurement systems are digitized at, for example, a sampling period TS and stored in a memory, and the measurement data stored in the memory is displayed at a display period TD (> TS) for each measurement system. The maximum value and the minimum value of the measurement data in the display period TD are sequentially read out and are graphically displayed on a two-dimensional display as line segments for each measurement system. Thus, it can be said that the inconvenience caused by the recording paper in the conventional recorder has been solved.

FIG. 10 shows an example of a display screen of a conventional paperless recorder using a two-dimensional display, and shows a display example in which "trend" is selected as a display mode.
In the figure, the display screen 1 is divided into three regions along an up-down direction: an upper region 2, a central region 3, and a lower region 4.

The upper region 2 is divided into three so as to digitally display three measured values. In the central area 3, only one “list screen”, “trend screen”, “setting screen”, or the like is displayed according to the display mode to be set.
The lower region 4 functions as a digital display unit for digitally displaying three measurement values similarly to the upper region 2 and also functions as an “operation information display unit” according to the display mode set. The example shows an example in which a “trend screen” is displayed in the central area 3 and the measured values are digitally displayed in the lower area 4 as in the upper area 2.

[0009]
