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]

As a conventional device of this kind, there is one shown in FIG. Here, the internal causes are the front view of the monitoring and control device (the standard view is the side view. In the figure, 1 is the fault indicator, 2 is the indicator, 3 is the recorder, and 4 is the various switching devices such as automatic/manual). 5 is a CRT that displays system diagrams, failure display contents, etc.
, 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. The first thing an operator should do in the event of an abnormal situation (starting/stopping the power plant, etc., or power generation plan) is to stand in front of the operation monitoring device and check the indicators 2 and recorder. 3 or after confirming the process data using a CRT 5 or the like, 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 to the specified value internal pressure.

Further, when an abnormality occurs, the failure is detected by the failure indicator 1, the detailed contents are grasped by the CRT 5, and the paper adjustment work is started by the operation station 4.

The clock 6 informs the operator of the 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 about 10 meters wide, by moving it back and forth and left and right, which requires a lot of skill. Naturally, there were problems such as the fact that the operation of the power plant was time consuming and required multiple operators.

This invention was made in order to solve the above-mentioned problems, and provides a power plant monitoring and control device that improves the work environment for power plant operators' monitoring operations and provides an optimal environment for operating operations. With the goal.

[Failure to solve the problem]

The power generation plant monitoring and control device according to the present invention consolidates conventional panel-mounted equipment into necessary operating terminals and replaces them with a display screen, and displays related system diagrams and related process data instantaneously for each operating terminal. Values and trend values are displayed to facilitate operation, and by selecting a menu on the menu window with the mouse, it is possible to display a desired system diagram or corresponding operation station screen.

[Effect]

The monitoring screen of the display device according to the present invention uses a bitmap display method and has a multi-window function, so that multi-function screens can be displayed on the same screen, and the required function screen can be selected using a virtual keyboard in the menu window. Select multiple screens by specifying with the mouse.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. 1st
FIG. (5) is a schematic diagram of the monitoring control device, and 100 is a monitoring operation screen. Also, in the same figure (Hitoshi is the above operation 1 screen 100
In the detailed diagram, 101 is a failure display window, 102 is an operation station window, 103 is an operation station at the operation end indicated by the 102 operation station window 102, 104 is an indicator related to the operation station 103, and 105 is an operation station at the operation station 103. Associated system display window 106 is a trend display window associated with operating 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. Further, FIG. 2 is a screen diagram showing another embodiment of the monitoring operation screen 100 shown in FIG. 1 (5)K.

Next, the operation will be explained. FIG. 3 is a flowchart showing the operating sequence of the power plant monitoring and control device according to the present invention. First, when the monitoring operation screen is opened in ST1, the system desired to be displayed is selected from the menu window 109 for selecting a system display window on the monitoring operation screen 100, and then the operating station is selected from the operation station selection menu window 108. Selection of each of these menu windows is performed by placing a cursor on the desired menu window and inputting an input using a mouse directly connected to the CPU, allowing quick selection of a plurality of screens. In this way, operations are performed in a predetermined order, and the monitoring operation screen is finally closed at ST, n. This series of operations is performed interactively by the operator facing the monitoring operation 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 push 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 by operating the mouse from the operating station selection menu window.

Furthermore, although the above embodiments have been shown to monitor and control boilers and turbines in thermal power plants, they may also be used to monitor and control hydraulic power plants or nuclear couplants, and the same effects as in the above embodiments can be achieved. play.

〔Effect of the invention〕

As described above, according to the present invention, the necessary monitoring operation screen can be selected using the mouse from the ergonomic viewpoint of monitoring operation without changing the functionality of the conventional extremely large operation monitoring device (BTG Iwa). Since the information is displayed, the operability of monitoring is greatly improved, and highly accurate and efficient operation monitoring performance can be obtained.
