  The best mode of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a block diagram for explaining a schematic configuration of a recorder according to the present invention, and FIG. 2 is an explanatory diagram showing a display example of the recorder according to the present invention.

  First, the schematic configuration of the recorder of this example will be described in detail with reference to FIGS. The recorder 10 of this example takes in contact signals and voltage signals from a plurality of terminal portions in addition to temperature signals from an external temperature detecting element such as a thermocouple or a resistance temperature detector, and receives these measurement data as electrical signals. The measurement result with the passage of the measurement time is two-dimensionally displayed, and is roughly composed of a display unit 11, a setting input unit 12, a storage unit 13, and a control unit 14.

  The display unit 11 is configured by a display device such as a CRT or a liquid crystal display, for example, and displays display contents based on a display control signal output from the control unit 14. As a display screen displayed on the display unit 11, for example, as shown in FIG. 2, the vertical axis is the time axis and the horizontal axis is the data amount, and the measurement waveform of the measurement data measured for each measurement location or channel is displayed. The waveform display area 11a is divided into the measurement value display area 11b that displays the measurement values corresponding to the displayed measurement waveforms. In the waveform display area 11a, a scroll bar 11c for scrolling the displayed measurement waveform in the time axis direction and switching display contents is displayed as necessary.

  The setting input unit 12 includes, for example, setting keys and operation keys that are manually operated by an operator, and is disposed at a predetermined position of the housing portion of the recorder 10. The setting input unit 12 includes various settings necessary for driving the recorder 10 such as measurement data recording start / stop, setting of the number of channels of measurement data to be displayed on the display screen, and display settings of various display contents. The various setting signals that are operated are output to the control unit 14. The setting input unit 12 includes mode switching / cancellation means 12a and item selection / display movement means 12b.

  The mode switching / releasing means 12a is operated when switching from the real-time trend mode, which is a normal display mode, to the historical trend mode to display desired display contents in the historical trend mode, and an operation signal indicating that the operation has been performed. Output to the control unit 14. The item selection / display moving means 12b is made up of, for example, up / down / left / right direction keys. The item selection / display movement means 12b is operated when selecting any of the display contents to scroll or select various display items. A selection / movement signal indicating movement in the direction is output to the control unit 14. The item selection / display moving means 12b can be used only when the displayed screen is scrolled in the time axis direction when the scroll bar 11c in the historical trend mode is displayed in an identifiable manner.

  In this example, as shown in FIG. 2, the “SCROLL” key is used as the mode switching / cancellation means 12a, and the direction key including the up / down / left / right selection keys is used as the item selection / display movement means 12b. Are arranged at predetermined locations.

When the “SCROLL” key is operated in the real-time trend mode, the real-time / historical switching mode is entered and the real-time trend mode is switched to the historical trend mode. At this time, the display screen is also switched from the display screen in the real-time trend mode to the display screen in the historical trend mode.
Further, when the “SCROLL” key is operated in the real-time / historical switching mode, the mode shifts to the scroll bar selection mode, and for example, the scroll bar 11c is surrounded by a frame of a color different from the background color so that the scroll bar 11c in the display screen stands out. It is selected to be identifiable, such as blinking.
Further, when the “SCROLL” key is operated in the scroll bar selection mode, the scroll bar selection mode is canceled and the state of the normal scroll bar 11c is restored.
Further, when the “SCROLL” key is operated in a state where the scroll bar selection mode is released, the mode is switched to the historical / real time switching mode, and the historical trend mode is switched to the real time trend mode. At this time, the display screen is also switched from the historical trend mode display screen to the real-time trend mode display screen.

  The direction keys are used as operation keys for selecting various display items and moving display contents in the real-time trend mode. Further, in the historical trend mode, in addition to selecting various display items, it is used when scrolling the waveform display area 11a. When operated in the scroll bar selection mode, the direction key functions only when the measured waveform displayed in the waveform display area 11a is scrolled in the time axis direction in units of display areas.

  The storage unit 13 is composed of, for example, a magnetic or optical storage medium or a semiconductor memory such as a ROM or a RAM, and in addition to various processing programs necessary for driving the recorder 10, the temperature input from an external temperature detection element. In addition to signals, various measurement data such as contact signals and voltage signals, signals of various keys operated by the setting input unit 12, various setting contents, and the like are stored.

  The control unit 14 is composed of, for example, a microcomputer such as a CPU, a ROM, or a RAM, and comprehensively controls the operation of each unit constituting the recorder 10 based on various processing programs stored in the storage unit 13. The control unit 14 includes a mode determination unit 14a and a display control unit 14b.

  The mode discriminating unit 14a determines whether the current mode is a real-time / historical switching mode, a scroll bar selection mode, or a historical / real-time switching mode based on the number of operation signals output when operating the mode switching / cancelling unit 12a. Which mode is being used is determined.

When the mode switching / cancellation unit 12a is operated in the real-time trend mode, the mode determination unit 14a outputs a real-time / historical switching signal for switching to the real-time / historical switching mode to the display control unit 14b.
When the mode switching / cancellation unit 12a is operated in the real-time / historical switching mode, a scroll bar selection mode switching signal for selecting the scroll bar 11c is output to the display control unit 14b.
Further, when the mode switching / cancellation unit 12a is operated in the scroll bar selection mode, a scroll bar selection mode cancellation signal is output to the display control unit 14b.
Further, when the mode switching / cancellation means 12a is operated in a state where the scroll bar selection mode is released, a real time / historical switching signal for switching to the real time / historical switching mode is output to the display control means 14b.

  The display control unit 14b generates a display control signal for performing display control of display contents displayed on the display unit 11 based on the display setting signal input from the setting input unit 12 and various signals output from the mode determination unit 14a. Output to the display unit 11.

Here, the display control will be described in detail. When the mode switching / cancellation means 12a is operated in the real time trend mode which is a normal display screen, the display control means 14b inputs a real time / historical switching signal from the mode discrimination means 14a, and based on this input, the real time trend A display control signal for switching from the display content of the mode to the display content of the historical trend mode is output to the display unit 11.
When the mode switching / cancellation means 12a is operated in the real-time / historical switching mode, the display control means 14b inputs a scroll bar selection mode switching signal from the mode discrimination means 14a, and based on this input, the display area In order to make the scroll bar 11c stand out, for example, the scroll bar 11c is displayed in a state of being selected so as to be identifiable, for example, surrounded by a frame of a color different from the background color or blinking. Then, a display control signal for enabling scroll movement in the time axis direction at a time in units of display areas on which the measurement waveforms are displayed is output to the display unit 11.
Further, when the mode switching / cancellation unit 12a is operated in the scroll bar selection mode, the display control unit 14b inputs a scroll bar selection mode cancellation signal from the mode discrimination unit 14a, and based on this input, the scroll in the display area is scrolled. The state where the bar 11c is selected is canceled, and a display control signal for returning the display movement range at the time of the scroll operation to the display state of the normal historical trend mode is output to the display unit 11.
Further, when the mode switching / cancellation means 12a is operated in a state where the scroll bar selection mode is released, the display control means 14b inputs a real-time / historical switching signal for switching from the mode discrimination means 14a to the real-time / historical switching mode. Based on this input, a display control signal for switching from the display content of the historical trend mode to the display screen of the real-time trend mode is output to the display unit 11.
That is, every time the mode switching / cancellation means 12a is operated, the display content is: real time / historical switching mode → scroll bar selection mode → cancellation of scroll bar selection mode → historical / real time switching mode → real time / historical switching mode →. As described above, the display contents are sequentially changed every time the mode is switched.

  Next, the operation method of the recorder 10 described above will be described with a specific example with reference to FIGS. As an operation method described below, every time the “SCROLL” key as the mode switching / cancellation means 12a is operated, the real-time toled mode is switched to the historical trend mode, the display scroll bar 11c is selected, and the selected scroll is selected. Using the recorder 10 that sequentially releases the bar 11c and switches from the historical toled mode to the real-time trend mode, the measurement data measured by the external temperature detection element is moved to the target time position and the desired measurement data is displayed. To do. In this example, the scroll bar 11c is scrolled on the display screen with the up and down direction keys, and when the scroll bar 11c is selected, the scroll bar 11c is displayed in a state surrounded by a frame of a color different from the background color.

  As shown in FIG. 3, when measurement data display is started, the display unit 11 displays display contents in the real-time trend mode, which is a normal mode. In the real-time trend mode, when the operator presses the “SCROLL” key 12a, as shown in FIG. 4, the normal real-time trend mode is switched to the historical trend mode, and the display screen is changed from the display contents of the real-time trend mode to the historical trend mode. Switch to the display contents. In this example, the background color of the waveform display area 11a is switched according to each mode so that the display of the real-time trend mode shown in FIG. 3 and the display of the historical trend mode shown in FIGS. Yes.

  Then, when the operator presses the “SCROLL” key 12a while switching from the real-time trend mode to the historical trend mode, as shown in FIG. 2, the scroll bar 11c is framed so that the scroll bar 11c displayed at the right end stands out. It will be in a selected state. In this state, the direction key 12b is operated to scroll the measurement waveform displayed in the waveform display area 11a in the time axis direction in the display area unit, and scroll the displayed measurement waveform to the vicinity of the target time position. Move. Then, after scrolling to the vicinity of the target time position, the “SCROLL” key 12a is pressed to cancel the selection of the scroll bar 11c, and the direction waveform 12b is used to scroll the measurement waveform to the target time position to obtain desired measurement data. Is displayed.

As described above, the recorder 10 described above operates the mode switching / cancellation means 12a in the real-time trend mode, shifts to the real-time / historical switching mode, switches to the historical trend mode, and switches / cancels the mode in the real-time / historical switching mode. The means 12a is operated to switch to the scroll bar selection mode so that the scroll bar 11c is selected. In this state, the direction key is operated to scroll the measured waveform displayed in the waveform display area 11a in the time axis direction in units of the display area, and scroll the displayed measured waveform to the vicinity of the target time position. After scrolling to the vicinity of the target time position, the mode switching / cancellation means 12a is operated to cancel the selection of the scroll bar 11c, and the item selection / display movement means 12b is used to scroll the measurement waveform to the target time position. To display desired measurement data.
As a result, even when there is a large amount of measurement data or when it takes time to move to the target time position, the measurement waveform displayed in the waveform display area 11a is scrolled in the time axis direction in the display area unit. Therefore, the search time can be shortened and the work efficiency can be improved, and the trend change of the measurement waveform from before the movement to after the movement can be confirmed even during the scroll movement.

  By the way, although the form mentioned above demonstrated the structure which operates display content control, such as switching of real time trend mode and historical trend mode, by operating the "SCROLL" key as mode switching / cancellation means 12a, it is limited to this. For example, a dedicated mode switching / cancellation means for switching between the real-time trend mode and the historical trend mode is newly provided in the setting input unit 12, and the mode switching and the scroll bar 11c selection / cancellation are performed by separate operations. You can also. Thereby, since mode switching and selection / cancellation of the scroll bar 11c can be performed by different key operations, the number of key operations is reduced, and the work is simplified.

  Further, although the scroll display screen has been described as being configured to scroll up and down with the up and down direction keys, for example, the scroll movement direction may be left and right. In such a case, the scroll movement can be moved with respect to the time axis by using the left and right direction keys instead of the up and down direction keys.

  As mentioned above, although the best form in this invention was demonstrated, this invention is not limited with the description and drawing by this form. That is, it is a matter of course that all other forms, examples, operation techniques, and the like made by those skilled in the art based on this form are included in the scope of the present invention.
