The operation icon includes selection of a relay operating display, selection of a defective point display, selection of a setting operation mode, selection of a helping function, etc., and display switching, operating instruction, etc., is inputted by moving the cursor 31 to a desired icon and clicking the button of a pointing device 27. The CPU 7 selects and executes a process by recognizing the operating instruction corresponding to the icon specified by the click.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an operation display device in a control and monitoring device for various plants.

[0002]

2. Description of the Related Art Generally, some digital protective relay devices, power control monitoring devices, and the like have a setting (setting) panel for setting and displaying various setting items. An example of the setting panel is shown in FIG. This panel includes indicator lamp panels 1 and 2, a digital display 3, and various operation keys 4 and 5. Further, a settling range table 6 in which the settling range of each element is described is attached. The indicator lamp panels 1 and 2 show status information such as the operation of the devices to be controlled and monitored, for example, relays of various relays, and the LEDs in the area indicated by the broken line in the figure are appropriately colored such as yellow. However, many items are displayed. The digital display 3 shows the element names, codes, set values, etc. of various elements. The operation key switches 4 and 5 include ten keys for inputting set values and various function keys. The circuit configuration of this setting panel is shown in FIG. Reference numeral 7 is a CPU which performs main control of this apparatus, and 8 and 9 are ROM and RAM which constitute a main memory. When the number of indicator lights and operation keys is small, as shown in FIG.
A latch circuit 11 that holds and outputs the lighting instruction from the LED 7 to the LED 10 and a buffer circuit 13 that receives an input signal from the key contact 12 are provided. If there are many indicators and operation keys, as shown in FIG.
There is also a mode in which a display / key input control interface (LSI) 14 for controlling display and matrix key input is used.

[0003]

This type of setting panel requires the number of indicator lamps in the indicator lamp panels 1 and 2 and the number of digital indicators 3 in response to a request from the equipment to be controlled and monitored and the mode of use. The number of digits is determined, and the arrangement of each element on the setting panel is designed based on this. Then, the panel printed board is designed based on the arrangement of each element. For this reason, the setting panel has no choice but to adopt an individual order manufacturing method, which complicates the manufacturing process and raises the manufacturing cost. In addition, if the content or number of relay elements or the like to be controlled and monitored is changed, there is a problem in that a new setting panel must be created and replaced according to this change.

In view of the above problems, the present invention provides an operation display device in a control and monitoring device of various plants, which standardizes a hardware system of a display operation panel and can cope with various devices and usage modes. The purpose is to provide.

[0005]

The structure of the present invention is shown in FIG. In order to achieve the above object, the present invention displays the status information and settling value of various devices to be controlled and monitored, and the operation display device of the control and monitoring system that controls the input of the settling value and various instructions. In, the following elements are provided.

(1) A graphic display device 19 having an information display column 16 for displaying state information and set value 15 and an operation symbol display column 18 for displaying operation symbols 17.

(2) Position input means 21 for inputting the position 20.

(3) An input instruction selecting means 24 for specifying the operation symbol 17 based on the input position 22 and selecting an instruction corresponding to the specified operation symbol as an input instruction 23.

[0009]

According to the present invention, various input instructions can be input by displaying the status information / setting value and the operation symbol on the graphic display device and designating the displayed operation key symbol by the position input means. By this,
It eliminates the need for indicator lights such as diodes and key switch members.

[0010]

Embodiments of the present invention will be described below. FIG. 2 shows a display operation device according to an embodiment of the present invention. In this figure, parts that are the same as or correspond to those of the related art are assigned the same reference numerals and description thereof is omitted. Reference numeral 25 is a graphic display, and it is possible to use a CRT device, but if a flat panel display such as a liquid crystal display or a plasma display is used, it is possible to avoid increasing the installation space. A graphic display interface 26 controls the graphic display 25. Reference numeral 27 is a pointing device, and a joystick, a mouse or the like can be used, but a trackball or the like is preferable in consideration of the state of the device. When there are many numerical inputs, the operation key switch 4 having a ten-key pad and various function keys is provided. An input interface 28 receives an input from the pointing device 27 or the like.

The display contents of the graphic display 25 are shown in FIG. A data display field 29 and an operation icon display field 30 are displayed on the screen of the graphic display 25. In the case of a system that controls and monitors the relay operation, the data display column 29 displays the target relay operation based on the relay operation state data provided from the CPU 7. On the other hand, the operation icon display column 30 displays operation icons for instructing control operation of the relay. The operation icons include, for example, relay operation display selection, inconvenient point display selection, settling operation mode selection, and help function selection. The operator operates the cursor 31 with the pointing device 27, clicks a desired icon, and inputs display switching, operation instructions, and the like. The CPU 7 recognizes the operation instruction corresponding to the clicked icon, and selects and executes the process based on the operation instruction.

[0012]

As described above, according to the present invention,
By displaying the status information and set values of the equipment under control and monitoring by the graphic display device, the display lamp such as LED is not necessary, and the operation symbol on the screen of the graphic display device is selected to input various operation instructions. This eliminates the need for operation key switches. Therefore, the hardware system of the operation display device can be standardized for the system in which different devices are controlled and monitored, and the manufacturing process is simplified and the cost is improved. In addition, even if a change occurs in the equipment to be controlled and monitored, there is an advantage that it can be easily dealt with by modifying the software.
