Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings so that those skilled in the art can easily carry out the technical idea of the present invention. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. In order to clearly explain the present invention, parts not related to the description are omitted, and like parts are denoted by similar reference numerals throughout the specification.

1 is a block diagram illustrating an integrated reactor safety grade soft controller in accordance with an embodiment of the present invention.

Referring to FIG. 1, the integrated reactor safety grade soft controller includes an indicator, a display controller, a controller, a touch controller, and a group controller. Further, the integrated reactor safety grade soft controller further includes a library database and a screen configuration database.

Specifically, the group controller (also referred to as the main controller) can receive at least one of the on-site valve state signals and pump state signals from the field. The group controller can deliver at least one of the on-site valve state signal and the pump state signal to the display controller.

The indicator may include an LCD configured to display screen information. The indicator can continuously display on-site valve status signals and pump status signals. As shown, the indicator can include a plurality of indicators (e.g., first and second indicators), wherein at least one of the valve state signal and pump state signal in the field is divided into each of the plurality of indicators Can be displayed. At this time, the group controller may store information about the screen provided for each of the plurality of display devices.

The display controller can control the screen information displayed on the display device. The display controller can control the indicator to continuously display the valve status signal and pump status signal of the field delivered from the group controller.

The controller may be configured to allow touch input. The operator can control the integrated reactor safety grade soft controller by applying a touch input to the controller.

The touch controller can receive control information from the controller. The touch controller may transmit at least one of coordinate information, navigation information, and control information of the controller to the group controller.

Then, the group controller can generate at least one of the on-site valve control signal and the pump control signal using at least one of coordinate information, navigation information, and control information of the controller received from the touch controller. Next, the group controller can deliver the generated signal to the site.

On the other hand, as shown, the indicators and controllers of the integrated reactor safety grade soft controller can be configured as separate hardware devices to be physically isolated from each other. That is, the display signal and the control signal can be processed in separate hardware, respectively.

An optical cable may be used to electrically isolate the group controller, indicator, and controller of such an integrated reactor safety grade soft controller from each other. Thus, the electrical failure of the indicator is not propagated electrically to the controller.

Also, with respect to communication, transmission of signals may be possible only from the controller to the display via the group controller. Thus, the failure of the indicator does not affect the controller.

2 is a conceptual diagram showing a main screen configuration of an integrated reactor safety grade soft controller. 3 is a conceptual view showing a detailed screen of the integrated reactor safety grade soft controller.

As shown in FIG. 2, the indicator of the integrated reactor safety grade soft controller can display a main screen capable of navigation.

The group controller may include a screen configuration database for navigation. The group controller transfers the valve state signal and the pump state signal of the field to the display controller, and receives the coordinate information, the navigation information, and the control information of the controller from the touch controller.

The display controller may include a library database for representing the target device. The display controller can continuously display the coordinate information, the navigation information, and the control information of the controller received from the group controller on the display device.

Meanwhile, as shown in FIG. 3, in addition to the screen capable of navigation, the indicator of the integrated reactor safety grade soft controller can display detailed information about each controller and display a detailed screen for inputting control commands.

That is, in addition to the indicator shown in Fig. 2 for the navigation function, a plurality of indicators shown in Fig. 3 can be used to display more information and to input a more detailed control command. The information may be divided and displayed in each of the plurality of display devices. At this time, the group controller may have information about each screen provided to each of the plurality of display devices.

4 is a conceptual view showing a display area and a control area of a detailed screen for controlling a valve of the integrated reactor safety grade soft controller. 5 is a conceptual view showing a display area and a control area of a detailed screen for controlling a pump of an integral nuclear reactor safety grade soft controller.

4 and 5, a first area (for example, a left area) of the screen area is a display area for displaying detailed information about each controller, and a second area (for example, ) Is constituted by a control area for receiving a control command.

By separating the screen area in this way, the operator can perform the minimum control function by using the controller, if necessary, even in case of a single failure of the indicator. Accordingly, as shown in the figure, a button for performing a specific control function is designed to be displayed in a fixed area (control area) of the screen area. These buttons may be formed to enable touch input.

4, the control area includes OPEN / CLOSE buttons 102 and 103 for controlling the OPEN / CLOSE of the valves, an EXECUTE button 104 for performing one confirmation at the time of inputting the control command, And CLR button 101 for removing the previous control command before / CLOSE command switching.

As shown in FIG. 5, when the pump is in a state where the current control command is STOP, and an input is applied to the EXECUTE button 104, the STOP control signal may be transmitted to the pump. To switch from STOP to START, the operator removes the STOP command by applying an input to the CLR button 101, then applies an input to the START button 102 and applies an input to the EXECUTE button 104. [ This design is intended to prevent accidents caused by careless behavior of the operator.

As described above, the navigation function of the integrated reactor safety grade soft controller can provide convenience to the operator, and can provide more information than analog devices.

In addition, the integrated reactor safety grade soft controller and its control method according to an embodiment of the present invention can prevent a careless control command from the operator without a failure of either the indicator or the controller affecting the other one , The existing command can be removed when the control command is switched. Accordingly, erroneous control due to a mistake of the operator can be prevented. As a result, the convenience of the driver can be improved.

As described above, the integrated reactor safety grade smart controller and its control method are not limited to the configuration and method of the embodiments described above, but the embodiments can be applied to all or some of the embodiments May be selectively combined.
