Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field of the Invention The present invention relates to a method for displaying VAM control data, control status, etc. based on priorities.

Control data and control status of conventional looms can be visually checked using a display unit. This allows the operator to easily check the control details and operating status of the loom at any necessary time.

The conventional screen display method is a kind of real-time processing, and the display items are arranged in the order in which they occur. That is, when a new change occurs in the display items on the loom side while the display unit is displaying a certain display screen, the screen is unconditionally switched and displayed to the new display items. For example, if a trouble occurs on the loom even when control data is being input, the display unit does not display the control data that is being input, but immediately erases it and forcibly switches to the trouble display screen.

According to this display method, the continuity of the operator's thinking is interrupted during the process of inputting control data, and when there are many display screens, complicated key operations are required to display the previous display screen. , the workability is poor and the display function cannot be used effectively.

OBJECT OF THE INVENTION Accordingly, an object of the present invention is to display a plurality of display screens showing control data and control status of a loom according to the degree of urgency and demand, thereby solving the above-mentioned drawbacks.

Solution to the Invention In view of the above object, the present invention provides a method for switching and displaying a plurality of screen displays such as control data and control status of a loom.
A priority order is set for the contents of the plurality of display screens, and a display screen is determined based on this priority order. Here, the priority order is set according to the level of urgency and level of demand.

For example, while control data is being input, the display screen for the control data is set higher than the display screen for trouble occurrence on the loom side. However, among the details of the trouble, matters with a high degree of urgency are set in a higher order than the display screen of the control data. Therefore, unless a trouble with a high degree of urgency or high demand occurs during the input of control data, the operator can continuously input the control data manually.

However, when a problem occurs that takes priority over the display of control data, the details of the problem with a high degree of urgency are displayed on the screen instead of displaying the control data, allowing the operator to quickly and appropriately respond to the problem. It will be possible to respond to

Configuration of Control System FIG. 1 shows the configuration of the control system in relation to a loom 1 to be controlled.

Control data for the loom 1 is input by the manual setting device 2, sent to the main control device 3 via the communication cable 4, and further sent to the sequence control section I3, the timing control section 15, and the sending-off control section 17, which will be described later.

This setting input device 2 has a built-in display unit 5, which displays control items input using a plurality of function keys 6, numerical values of data entered manually using numeric keys 7, etc. based on a display program. Displays the contents of the control status of machine 1 during operation, which has been read into main controller 3. This manual setting device 2 has a built-in card reader 9 as required. Therefore, a specific portion of the control data can also be input using the memory card 8.

This memory card contains the weft thread selection patterns set in the weft thread selection device (not shown) and the control units 13, 15.
17 control data can be stored. Note that these control data can be input only when the key 10 of the setting input device 2 is set to the on state. This protects the data inside the main controller 3.

A printer can also be connected to the main control device 3 to print out part or all of the control data.

The main controller 3 then communicates via the communication line 11,
Sequence control section 13 of drive motor 12, timing control section 15 of wefting device 14, and feeding device 16
They are each bidirectionally connected to the sending control section 17 of the . Note that this communication line 11 is configured as, for example, an optical communication line, and is prepared for electrical noise accompanying the main movement of the loom 1. Therefore, control data and the like are not affected by noise and can be communicated in large quantities.

The sequence control unit 13 controls the direction and amount of rotation of the drive motor 12 and drives the main shaft 19 in accordance with a preset sequence based on commands from a command switch 18 for running, stopping, inching, etc. This drives the flattening device 20, shedding device 21, winding device 22, etc. that are interlocked with this.

Further, the timing control unit I5 compares the control data with the rotation angle of the main shaft 19 detected by the encoder 23 based on preset control data, and locks the length measurement storage device 24 at the set timing. The forward and backward movement of the pin 25, the opening and closing states of the solenoid valve 27 of the main nozzle 26 for weft insertion, and the solenoid valve 29 of the sub nozzle 28 are controlled, and the weft thread 30 is wefted.

Further, the feed-out control unit 17 adjusts the tension of the warp yarns 31 set by the control data to a target tension value.
The sending device 16 is driven.

Input of control data Input of control data is executed based on the control data input program shown in FIG.

When the operator turns on the key 10 of the setting input device 2 and presses the interrupt function key 6, a control data input program is started. This input is performed by specifying the control item using the function keys 6 and then operating the numerical keys 7 to specify the data value. Namely, first of all, the function keys? When a control item is specified by the judgment, a flag l is set, a control item corresponding to the function key 0 is set on the display screen 1, and then a level l flag is set. After this, flag 1 cent? After confirmation, press the number key? When the determination is made and the numerical value of the control data is being input, flag 2 is set, then the control item and numerical value are set on display screen 1, and the level 1 flag is set in the same way as above. Ru. After this, 2 flags set? After confirmation, interrupt end key? is confirmed, and when that key is being operated, flag 1 and flag 2 are reset, the control data, that is, the content of control items and numerical values, is sent to the main controller 3, and the content is further transferred to the corresponding key. sent to the device. After this, the level 1 flag is reset and f
frl? The wholesale data input program ends.

Note that the control unit 13.15.17 has a human power restriction function, stores upper and lower limits of control data,
Changed control data is imported only within that range. If the control data input through the setting input device 2 is sent from the main controller 3 and exceeds the allowable range, the controller 13.15
．． 17 sends a data input error signal to the main controller 3, which causes the main controller 3 to display to the operator on the screen of the setting manual device 2 that the data value is outside the permissible range, and to notify the operator as necessary. An alert will be issued accordingly.

The control state reception main controller 3 executes the control state reception program shown in FIG. 3 at a predetermined sampling period when the fabric m1 is in operation or in an operable state, and the sequence control unit 13,
It communicates with the timing control section 15 and the sending control section 17, and receives their control states.

First of all, does the receiving program in this control state cause a problem? If no trouble has occurred, the level O12 flag is reset, but if a trouble has occurred, the level 0 trouble? make a judgment,
If the cause of the trouble falls under level O, a level O flag is set and display screen O is set on the display unit 5.

If it is not a level 0 trouble, the level 0 flag is reset, the level 2 flag is further set, and a trouble display is set on the display screen 2. continue,
Is there a cause for the program to stop? If there is a cause for the stoppage, the cause of the stoppage is displayed on display screen 3.
Set the level 3 flag. However, if there is no cause for the stoppage, the level 3 flag is reset, the status of each part is set on the display screen 4, and the display program is terminated.

Display method of the present invention In parallel with the control data input program and control state reception program described above, the display unit 5 executes the display program shown in FIG. 4.

In the case of FIG. 4, the priority order is level 0 - level l.
- They are set in the order of level 2 → level 3 →. Therefore, after the display program is started, after the sampling period for executing the receiving program in the control state has elapsed, that is, at the display screen switching period, the level 0 flag is set?
, level 1 flag set? , level 2 flag set? ,
Level 3 flag set? Check the flag setting status in priority order.

When the level O flag is set in the control state reception process, the level O flag is checked first in the flag setting determination process, so the display unit 5
displays the items corresponding to the contents of the display screen O, that is, the items with the highest degree of urgency and demand among the troubles, with the highest priority.

However, when no trouble corresponding to the highest priority level 0 has occurred and the flag corresponding to level 1 is set, that is, when the operator inputs control data based on the control data input program. During this time, the display unit 5 displays the display screen 1 and sequentially displays the control items and data values of the control data. Therefore, even if the flag corresponding to level 2 or level 3 is set while the operator is inputting control data, the control data display screen 1 continues to be displayed.

Therefore, the operator can continuously change the control data while maintaining the continuity of thinking about the data. Of course, if a problem corresponding to level O occurs during the process of changing this control data, the display program will
The level 0 flag is flushed, priority is given to the level 1 flag, and trouble details with a high degree of urgency are displayed.

If the level 0 and level 1 flags are not set, does the display program set the level 2 flag? When the problem exists, the display screen 2 is displayed to display the details of the low-urgency trouble.

Next, the display program will set the level 3 flag? Based on the judgment, display screen 3 is displayed at the time of setting,
The cause of the stop is displayed on the display unit 5.

Furthermore, in the next order, when all the flag sets do not exist, the display unit 5 displays the display screen 4 and displays the control status of the loom 1, such as the current warp tension and the crank angle while it is stopped. To go.

In this way, the display unit 5 sequentially switches and displays a plurality of display screens showing control data, control status, etc. according to preset priorities, that is, the degree of request and the degree of urgency. This allows the operator to continue inputting control data while inputting control data, excluding the most urgent display content and giving priority to display content that is lower than the control data input display. In this embodiment, troubles with a high degree of urgency are ranked higher than the control data display screen. Of course, unless there is a problem with a high degree of urgency, the priority of the control data display screen should be set to 1.
If there is a matter with a high degree of urgency or demand other than trouble, the display of that matter will be given top priority.

Other Embodiments The display unit 5 is planned to display only one display screen alone, but the display surface of the display unit 5 may be divided into a plurality of display surfaces, or or by configuring a plurality of display surfaces, for example two display surfaces.
The above display screens can also be displayed simultaneously. In this case, display items with higher priority can be displayed on the first display screen, and display items with lower priority can be displayed on the second display screen at the same time.

Effects of the Invention In the present invention, priority is set for the contents of a plurality of display screens that are highly requested or urgent.
The display function can be effectively utilized. That is, the display contents are displayed in a state that is compatible with the work procedure, thereby allowing input of control data and troubleshooting to be performed quickly and appropriately in accordance with the work procedure.
