2. Description of the Related Art In the paper industry, basis weight, moisture content, paper thickness, gloss, color, and the like are measured as paper quality. In order to display the quality of the paper, a device for displaying a profile as disclosed in Japanese Utility Model Application Laid-Open No. 63-175198 proposed by the present applicant is used.
FIG. 4 is a configuration block diagram illustrating a conventional profile display device. In the figure, a sensor 10 measures the basis weight and the like of paper manufactured by a paper machine. For example, a radiation basis weight meter or an infrared moisture meter is used. The profile data acquisition setting device 20 acquires, as profile data, a distribution of a measured value PV measured by the sensor 10 in the paper width direction, an operation amount MV of an operation end such as a slice bolt, and a set value SV of paper quality as profile data. The measurement position in the paper width direction of the sensor 10 and the measurement value PV are combined. The profile data holding device 30 stores the measured values measured at several tens to several hundreds points in the paper width direction in units of scanning of the sensor 10 in the paper width direction. The display device 40 displays the measured value PV, the manipulated variable MV held in the profile data holding device 30,
The set value SV is displayed as a distribution in the paper width direction. The input device 50 transmits a set value SV and an operation amount MV to the display device 40.
Manual specification.

FIG. 5 is an explanatory view of a display screen of profile data. FIG. 5A shows a profile display of a measured value PV and a set value SV, FIG. 5B shows a profile display of an operation amount MV,
(C) is a display of a position cursor. The measured value PV and the set value SV are represented by a line graph, and the manipulated variable MV is represented by a bar graph. The horizontal axis of the graph is the position in the paper width direction. The position cursor is displayed below the profile display section of the operation amount MV, and also serves as an input of which operation end is to be selected.

In such an apparatus, the position cursor is moved by the input device 50 and the set value SV and the operation amount MV are set.
To identify. Next, the setting value SV and the operation amount MV are changed according to the input operation, and the values are transmitted to the holding device 30. Further, the setting operation is performed by the profile data acquisition setting device 20.
Tell The measured value PV, the operation amount MV, and the set value SV held in the profile data holding device 30 are updated by the profile data acquisition / setting device 20 or the input device. The measured value PV and the manipulated variable MV are set in a paper machine control device (not shown), and PID control and fuzzy control are performed so that the profile matches the target value.

[0005]

However, in recent years, the basis weight CP control for locally adjusting the pulp concentration of the inlet by opening and closing a number of valves arranged in the width direction of the paper has begun to be adopted. Compared with the conventional grammage control for adjusting the slice bolt, the number of the operation ends MV is considerably large, and for example, the number of valves may reach several hundreds. Then, there is a problem that the operation end displayed on the display screen of the profile data becomes thin, and it becomes difficult to specify the operation end using the position cursor. SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problem, and has as its object to provide a paper machine control device that can easily be specified by a position cursor even when the number of operation ends increases.

In order to achieve the above object, a paper machine control device according to the present invention comprises a sensor
0 is the measured value PV measured in the paper width direction, the operation amount M of the operation end
V, profile data acquisition setting device 20 for acquiring the distribution of set value SV of paper quality as profile data
A profile data holding device 30 for holding profile data acquired by the profile data acquisition setting device; and a display for displaying measured values, operation amounts, and set values held in the profile data holding device as a distribution in the paper width direction. In a paper machine control device having a device 40 and an input device 50 for manually specifying a set value or an operation amount on a display device, an enlargement display means for enlarging and displaying the operation amount of the operation end in the paper width direction is provided. It is characterized by having been provided.

According to the first aspect of the present invention, since the enlargement display means for enlarging and displaying the operation amount of the operation end in the paper width direction is provided, the number of operation ends is remarkably large as in CP control of the basis weight. Even if the operating device displayed on the display device is thin,
The operation end can be smoothly selected by enlarging the display.

In this case, when the measured value and the set value are displayed in an enlarged manner in the paper width direction at the same ratio as the operation amount of the operation end, the selection of the operation end can be performed. Since the measured value and the set value corresponding to the position in the paper width direction can be referred to, selection errors can be reduced.
