DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described in detail with reference to the accompanying drawings.

Referring to Figures 1 to 7 with respect to the procedure computer processing system and method of the nuclear power plant according to the present invention will be described.

1 is a block diagram of a procedure manual processing system of a nuclear power plant according to an embodiment of the present invention, as shown in the procedure manual processing system of a nuclear power plant, a plurality of control target devices 10, a plurality of terminals (100) ) And the server 200.

The control target device 10 performs a command according to the command of the server 200 and transmits the result and the current progress state to the server 200.

The terminal 100 includes an input unit 110 for inputting procedure information and a command, a transceiver 120 for transmitting and receiving information with the server 200, a display unit 130 for displaying the transmitted and received information, and a procedure for creating a new procedure document. Composer 140, a procedure editing section 150 for editing the existing procedure is made. In addition, the terminal 100 may be operated by individual operators belonging to one driver's vehicle, and may receive information from the server 200 by requesting procedure document information, device information, and real-time information from the server 200, and a command. The control target device 10 may be operated by transmitting the control unit 10.

As shown in FIG. 2, the display unit 130 includes a two-dimensional flow diagram representing a flow according to the procedure in two dimensions, a logical tree diagram representing each step information according to the procedure, and real-time information of devices controlled according to the procedure. It is made, including. The screen is divided into two-dimensional flow charts (see FIG. 2A) on the left side, the logical tree diagram (see FIG. 2B) on the upper right side, and the state of the control target devices 10 on the lower right side. Display the device status window (see FIG. 2 (c)).

As shown in FIG. 3, the two-dimensional flow diagram shows a flowchart in two dimensions using a plurality of symbols. Use an action symbol with one output at one input, a check symbol with multiple outputs at one input, and a proxy symbol to indicate adjacent steps in the procedure. Therefore, the two-dimensional flow chart can minimize the overlap of the arrows compared to the one-dimensional array, it is easy to recognize, and can effectively use the space.

In addition, the two-dimensional flow chart shows the steps performed, the steps being performed, and the steps to be performed by color. Generally, the flow chart is performed one step at a time, but the procedure can be performed by moving to a specific step according to the actual situation of the power plant. To do this, select a specific step in the two-dimensional flowchart and execute the procedure from any step with commands such as move in the context follow menu of the step.

In addition, the two-dimensional flow chart may be folded to show all the contents of the procedure document, or may be unfolded to show the detail area in detail. Unfolding and folding takes place with one click. The nodes that unfold and fold are the step nodes. In the current step, more detailed information is displayed through the logical tree diagram at the upper right side, and real-time information of the control target device 10 for determining the logical tree diagram is displayed at the lower right side.

4 is a hierarchical exploded view of a procedure document according to an embodiment of the present invention, showing a framework for decomposing the procedure document. A procedure is divided into a number of steps, each of which consists of actions and checks.

The action is broken down into six unit commands, Set, Message, Initiate, Finish, Input, and Caution, and one recursive command, Action. Recursive commands allow you to create nested logic trees and easily express complex procedural logic.

The Set command is used to operate a valve or a pump ON or OFF. The Message is used to direct the driver to the task, the Initiate to open another procedure, the Finish to close the current procedure, and the Input is used to temporarily store a specific value. And the above Caution is used to alert the operator.

The check is divided into three unit instructions, AutoCheck, Mancheck, and Caution, and a recursive instruction of Check. The autocheck is used to determine a particular proposition through the real-time process variable of the power plant, and the mancheck is used to manually determine the proposition which is difficult for the computer to judge. These unit instructions have three states: true, false, or unknown. For example, the Message command is initially false but changes to true if the operator executes the unit command. Each unit command is represented by a logical tree and the appropriate user interface. Therefore, the user can intuitively execute the procedure book easily, and if he learns how to use at least nine unit commands, any kind of procedure book can be executed without error.

The logical tree diagram further illustrates the steps currently being performed in the two-dimensional flow diagram as shown in FIG. 5. This graph is combined by the n out of m operator. The operator is true if n of m items is true. In general, the procedure execution is connected by IF-THEN, OR, AND, etc. The present invention operates through the two-dimensional flow chart and the operator. The items enclosed by the above operators are the unit instructions of the procedure execution. A unit order can have three states: true, false, or unknown, depending on the plant state or operator action.

The device status window of the control target device 10 may be intuitively recognized by displaying the symbols instead of the plain text using the symbols shown in FIG. 6. In addition, the symbol is dynamically drawn according to the real-time information of the control target device 10, rather than using a static picture file. The symbol form is drawn in vector graphics to be integrated with the control and monitoring symbols of the plant. When editing the procedure document, the power plant symbol is referred to as a tag name, and the shape of the symbol and the actual power state of the tag name are linked to the tag name, so that the symbol can be drawn only by the tag name.

The structure of the display unit 130 is not limited and may be variously modified and implemented according to an installation place or components provided therein.

The procedure writing unit 140 creates a procedure when there is no procedure to be used in the procedure memory unit 220 of the server 200. The procedure document creating unit 140 creates a procedure document according to a preset standard. The procedure book may be easily prepared by using the tags and symbols of the procedure writing unit 140, but may be written by a general text editor when understanding the preset standard of the present invention.

The procedure editing unit 150 receives and edits the procedure in the procedure memory unit 220 of the server 200 when the procedure document in the procedure memory unit 220 of the server 200 is to be modified, and then the server 200 again. Procedure to transmit to the memory unit 220 to be stored.

The server 200 stores the data of all devices, the transceiver 210 for transmitting and receiving information to and from the plurality of terminals 100 and the control target device 10, the procedure memory unit 220 for storing data of the procedure document, and the like. The device memory unit 230, the real-time memory unit 240 that stores the progress and status of all devices included in the procedure, the control unit 250 for managing the device controlled according to the command received from the terminal 100 ) In addition, the server 200 transmits the device information and real-time information of the devices associated with the corresponding procedure to work in the terminal 100 to the terminal 100. Therefore, the server 200 transmits only the device information associated with the procedure to the terminal 100, thereby reducing the amount of data transmitted and received.

In addition, the controller 250 receives device information associated with a procedure to be currently performed in a plurality of terminals from a device memory unit, and transmits a command or status check request signal to a corresponding control target device 10 from a transceiver unit. The terminal transmits the real-time information related to the procedure currently being performed to the terminal.
