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 memory input / display device for monitoring and operating in a distributed control and monitoring system.

[0002]

2. Description of the Related Art A conventional man-machine interface (operator and machine connecting device) has functions such as screen display, signal display, alarm (warning) display and various operations necessary for plant operation. Based on the information, the operator (operator) operates the plant.

However, this function is built in advance, and notes that the operator noticed online (during operation) and points that need attention when handing over between operators are paper notes or man-machine. The only method taken is to take a hard copy (mechanical copy) of the interface screen and make a note of it. This made it difficult to manage information on paper during operation.

[0004]

A man-machine capable of inputting and displaying a memo on a conventional man-machine interface screen in order to reduce the operator's paper-based information management effort when operating a plant. It is intended to provide a memory input / display device for an interface.

[0005]

A memo input / display device for a man-machine interface according to the present invention comprises a touch input device for inputting information by touching a man-machine interface display screen of a CRT device. The man-machine interface screen memory that stores the output touch signal, the electronic pen input device that inputs memo information using the electronic pen on the man-machine interface display screen, and the memo signal output from the electronic pen input device A screen memory for memo to be stored, a keyboard for inputting control / display signals to the screen memory for man-machine interface or the screen memory for memo, and the input side is connected to the keyboard and the output side is for man-machine interface screen memory or memo screen It is equipped with a changeover switch that switches to memory and connects It is.

BEST MODE FOR CARRYING OUT THE INVENTION Next, an embodiment of a memo input / display device of a man-machine interface according to the present invention will be described. In FIG. 1, a touch input device 2 is a device for touching a man-machine interface display screen 1A of a CRT (cold cathode ray electron tube) device 1 and inputting information. The man-machine interface screen memory 3 is a storage device that is connected to the touch input device 2 and stores the touch signal 2a output from the touch input device 2. The electronic pen input device 5 displays the electronic pen 1 on the display screen 1A for man-machine interface.
This is a device for inputting memo information using 0. The memo screen memory 7 is a storage device that is connected to the electronic pen input device 5 and stores the memo signal 5a output from the electronic pen input device 5. The keyboard 4 is a device for inputting control / display signals to the man-machine interface screen memory 3 or the memo screen memory 7. The changeover switch 6 is a device whose input side is connected to the keyboard 4 and whose output side is switched to the man-machine interface screen memory 3 or the memo screen memory 7 for connection.

Next, a display example of the CRT device is shown in FIGS.
Shown in Figure 2 shows the conventional man-machine interface (MM
I) A display example by the function, and FIG. 3 is an embodiment of the present invention. When the operator needs to make a memo (record) during the display of this screen, the changeover switch 6 is changed to the memo input side. , Input a memo with the electronic pen 10 or the keyboard 4.

When the electronic pen 10 approaches (accesses) the CRT device 1, a mark can be displayed (checked) on the man-machine interface display screen 1A. In FIG. 3, 8 is an electronic pen display. Further, it is possible to display the content (comment) of the input from the keyboard 4 only at the designated position (or fixed position) with the electronic pen 10. 9 is a keyboard input display. Inputs from the electronic pen 10 and the keyboard 4 are stored (recorded) in the memo screen memory 7.

This operation can be performed while the man-machine interface is operating (online).

Input or display of this memo is performed on all screens of the man-machine interface display screen 1A (plural screens).
The memo display can be performed in correspondence with the man-machine interface display screen 1A.

Further, the memo screen memory 7 has a memo display list screen 11 as shown in FIG. 4, which displays a list of information on the man-machine interface screen on which memos are written, the date and the like. This is an index function that expands the touch (contact) operation from the memo display list screen 11 to the screen where memos (records) are made.

As another embodiment, instead of displaying a memo on the entire screen as in the embodiment, freely inputting or displaying a memo in a predetermined range, or comment data input by a keyboard is stored as a history data in a database. Saved and managed in, and connected to the database, it will be used for the operation support after alarm message display and voice message.

As described above, in this embodiment, since the precautions can be displayed online (in operation) on the man-machine interface screen for operation, it is not necessary to compare the CRT with the paper surface, and the CRT 1 The effect is that the operator can concentrate on the points.

[0014]

According to the present invention, the operator's comments managed on paper can be digitized, and waste paper is not used.
There is an effect that management becomes easy.
