Abstract

PURPOSE:To acquire tracking information with high accuracy in real time by receiving a position of a controlled system in a prescribed area from process data and applying coordinate conversion to the data, thereby displaying the data in a scale graph corresponding to the position. CONSTITUTION:This man-machine interface is provided with a microcomputer 1, a CRT 2, and a key board 3. Then a closed area 38 to be controlled is an area through which a cast iron piece passes and a start line 25 indicates a meniscus indicating start of casting and an end line 27 represents a position of a cutter. Then a scale generating line 24 and an auxiliary lien 26 correspond to a distance from the meniscus when the coordinate of the start line 25 is set to O. A cross line 28 depicts a position at a tail end of the iron piece and obtained from process points 30, 31 resulting from converting process data Pv(L) into a parameter. A cross line 29 indicates a position of a tip of the cast iron piece and obtained from process points 32, 33 resulting from converting process data Pv(H) into a parameter. Then an area 38 surrounded by points 34-37 shows a position of the cast iron piece and it is displayed in color on the CRT.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a man-machine interface device for monitoring a controlled object such as plant equipment in real time.

[0002]

2. Description of the Related Art Conventionally, it is necessary to monitor the entire plant equipment.
When the machine interface device is used, the status of the continuous casting equipment and the process line is provided to the operator in real time as tracking information by the method shown in FIG. FIG. 6A shows an example of continuous casting equipment. The molten steel coming out of the casting nozzle is guided horizontally by pinch rolls during the solidification process to produce a continuous slab, but the state (position) of this slab is displayed graphically as a man-machine interface. In addition, cut the passage of the slab into small pieces of any size,
Make into parts. Each of the pieces cut into pieces has display color information and position information (casting length range that the part handles). At this point the display is defined. Next, based on the process data obtained from the controlled object as a data processing unit,
Convert to information corresponding to the above parts. Each component determines the display color based on this converted information. By this, the position display of the slab is provided to the operator as graphic information. FIG. 6B shows an example of a process line, but this also cuts a continuous object into pieces of an arbitrary size to form parts. The method is similar to the above.

[0003]

However, in the prior art, since the tracking display is displayed by dividing it into parts, the accuracy of the information is low, and in order to compensate for it, the amount of software is enormous. Therefore, the problem to be solved by the present invention is to improve the accuracy of tracking display and reduce the amount of software.

[0004]

In order to solve the above-mentioned problems, a man-machine interface device having a scale graph function in a closed region of the present invention is a man-machine interface for monitoring a controlled object such as plant equipment in real time. In the interface device, a closed region representing the entire movement region of the controlled object, at least two lines along the movement route of the controlled object in the closed region, and both ends of the closed region along the movement route of the controlled object. A data input unit that presets a starting line and a ending line that are in contact with a starting point and an ending point that are, a data storage unit that stores data indicating the leading end and the trailing end of the control target obtained from the control target, and the control target The cross data representing the front end position and the rear end position of the controlled object in the closed region is calculated by operating the data obtained from It is obtained by a graphic means for displaying a scale graphs on the display area in the closed area sandwiched between the cross-line as the current position of the controlled object. The current position of the controlled object can be displayed in a display color that can be distinguished from others.

[0005]

Originally, the scale graph had only a rod-shaped or circular shape, and the graph was also shown as a closed region. Although the shape of the passage path of the slab or the like is arbitrary, it can be considered as a closed region. In the present invention, a closed area representing the entire movement area of the controlled object, at least two lines along the movement path of the controlled object in the closed area, and both ends along the movement path of the controlled object in the closed area. A starting point and an ending point that contact with a certain starting point and ending point are set in advance, the position of the controlled object in this area is input from the process data, and the area corresponding to the position is converted into coordinates on the display, that is, the scale. Display as a graph. In addition, display color is added to this. As a result, highly accurate tracking information can be provided in real time.

FIG. 4 is a flow chart of the scale display means in one embodiment of the present invention, which will be described with reference to FIG. 4 in order from data input to the data input unit 19. Step 1
01 is used to determine the closed region 4, the starting line 6, the ending line 8, the scale bus 9 and the auxiliary line 10, the number of process data, and the maximum value of the process data. The area 4, the starting line 6, the ending line 8, the scale bus 9 and the auxiliary line 10 are determined by operating the keyboard 16 and mouse 17, and the display color and the ratio of the process data and the scale bus are set on a storage medium such as a floppy disk. The scale format including the closed region is determined by the processing logic and the arithmetic logic stored in advance in 18. Next, the scale format determined in step 101 has an upper limit of 100 and a lower limit of 0 in step 102, which is determined by the scale processing means, in which the scale is determined. The following is a step for displaying, but in step 103, data is taken in from the data storage unit 23 that stores the process data obtained from the controlled object, and the maximum value set in step 101 is 100 as a percentage value. Convert to. This leads to step 10
At 4, the process points on the scale bus 9 and the auxiliary line 10 are determined. The process points determined in step 104 are the two points that determine the cross line 13 in step 105, and the cross points 11 and 12 that are the intersections of the cross line 13 and the closed region obtained here are determined in step 106. It When there are a plurality of process data in step 107, the process returns to step 103 again, the number of process data is added in step 108, and step 1
The process data is repeated by the number of process data set in 01. When N = n in step 107, the process moves to step 109, the closed region obtained by the cross line 13 is determined, the display color of the closed region 4 is determined in step 110, and it is displayed on the CRT in step 111. It Since the process data is updated according to the data collection cycle, the update of the data is determined in step 112,
Returning to step 103, the flow is repeated. With the above steps, it becomes possible to provide the scale graph function in the closed region. In the above embodiment, the two lines along the movement path of the controlled object in the closed region are defined by the scale bus 9 and the auxiliary line 10. However, instead of the scale bus 9 connecting the starting point and the ending point, another line is used. You may use an auxiliary line.

The scale bus 24 and the auxiliary line 26 correspond to the distance from the meniscus with the origin 25 as 0, and the distance to the end line 27, that is, the cutter is 100. The cross line 28 (L) indicates the rear end position of the slab, and is obtained from the process points 30 and 31 obtained by converting the process data P _{V (L)} into parameter values.
