Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a monitoring and control device for a power generation plant.

[Conventional technology]

A conventional device of this type is shown in FIG. Here, figure (3) is a front view of the monitoring and control device, and figure (3) is a side view. In the figure, 1 is a fault indicator, 2 is an indicator, and 3 is a fault indicator.
is a recorder, 4 is an operation station including various automatic/manual switching devices, and 5 is C for displaying a system diagram, failure display contents, etc.
RT, 6 is a clock. Further, 7 is an industrial television that displays the combustion state inside the boiler, the water intake, and the vicinity of the boiler's safety valve.

Next, the operation will be explained. First, the power generation plan ′
The first thing an operator should do when starting or stopping a power plant, or when an abnormal condition occurs in a power plant, is to stand in front of the operation monitoring device and use indicator 2, recorder 3, CRT 5, etc. After confirming the process data, an adjustment command is output from the operating station 4 to the operating end as a result of the data confirmation, and the process amount is adjusted within the specified value. Further, when an abnormality occurs, the details of the failure are confirmed on the failure display 1, the detailed contents are grasped on the CRT 5, and adjustment work is started using the operation station 4. Further, the clock 6 informs the operation negative pressure time, has a second hand in principle, and is linked to a master clock such as a computer.

The industrial television 7 is a surveillance television that allows inspection and monitoring of necessary locations by remote control from the central control room where the operation monitoring device is installed.

[Problem that the invention seeks to solve]

Conventional monitoring and control equipment is configured as described above, so power plant operators have to monitor and operate the control panel, which is approximately 101 rL wide, by moving it back and forth and from side to side. It is essential that the power generation plant be operated properly, which naturally poses problems such as the fact that it takes time and effort to operate the power plant, and multiple operators are required.

This invention was made in order to solve the above-mentioned problems, and it displays the necessary display functions on a single display device to improve the work environment for monitoring operations of power plant operators, and The objective is to obtain a power generation plant monitoring and control device that provides an optimal environment for operation by using a touch panel type screen.

[Means for solving problems]

The power plant monitoring and control device according to the present invention houses the conventional panel-mounted equipment in units of necessary operating terminals and replaces them with a touch panel type display device screen, and displays related system diagrams and related processes for each operating terminal. Instantaneous data values and trend values are displayed using a bitmap multi-window function to facilitate operation.

[Effect]

The monitoring screen of the display device according to the present invention has a multi-window function using a bitmap display method, and can display multi-functional screens on the same screen.
The desired function screen can be selected from a virtual keyboard, such as a touch panel of a computer input device.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. 1st
1 is a schematic diagram of the monitoring control device, and 100 is a monitoring operation screen. In addition, in the same figure) is the monitoring-operation screen 10.
0, 101 is a failure display window, 102 is an operation station window, 103 is an operation station at the operation end indicated by the operation station window 102, 104 is an indicator related to the operation station 103, and 105 is an operation station. 103 is a busy-related system display window, and 106 is a trend display window related to the operation station 103. A clock window 107 is updated every second in conjunction with the master clock and has a calendar function. 108 is a menu window for selecting an operating station window; 109 is a menu window for selecting a system display window; the menu window 108 for selecting an operating station, the operating station window 102, and the trend display window 106 change in conjunction with each other.

FIG. 2 is a screen diagram showing another embodiment of the monitoring operation screen 100 shown in FIG. 2(5). Furthermore, FIG. 3 is a flowchart showing the operation order of the power plant monitoring and control device according to the present invention. When the monitoring operation screen is opened at ST, 1, the following operations are executed based on a predetermined operation selection procedure, and at ST, 8T, n. At this point, the monitoring operation screen is closed, and one monitor and one operation is completed. Here, the desired display screen is selected by touching the points on the touch panel arranged on the monitoring operation screen, that is, the menu windows 108 and 109 for selecting various functions. These operations can be performed interactively by the operator facing the display screen, eliminating the need for the operator to stand and move.

In addition, although the analog control loop was shown in the above embodiment, the same concept applies to the auxiliary equipment operation logic.
Operation presses and buttons are displayed instead of the operation station window, and a logic window is displayed instead of the trend display window. This selection can be made from the operating station selection menu window.

Furthermore, although the above embodiments have been described with respect to the monitoring and control of boilers and turbines in thermal power plants, the above embodiments may also be used in the case of monitoring and controlling hydraulic power plants, or in the case of monitoring and controlling nuclear couplants. It has a similar effect.

〔Effect of the invention〕

As described above, according to the present invention, the desired system and operation station can be displayed on the screen from the ergonomic standpoint of monitoring operation without making any functional changes to the conventional extremely large operation monitoring device (BTG panel). Since it is possible to select and display arbitrary nine items using the touch panel method, the driving monitoring device can be made small and inexpensive, and the operability of monitoring is greatly improved, resulting in highly accurate and highly efficient driving monitoring performance.
