Embodiment Construction

[0041] The technical solutions of the present invention will be described in detail below in conjunction with specific embodiments.

[0042] A method for controlling flashing and synchronous optical nameplates of the present invention is applied to the control system of BUP optical nameplates in a DCS system of a nuclear power plant, comprising the following steps:

[0043] (1) Get the system time;

[0044] Use the functions provided by the DCS platform to obtain the system time, so that the clocks of each control station in the control system of the BUP optical plate of the DCS system of the nuclear power plant are consistent with the external clock source; the clocks of each control station in the control system of the BUP optical plate of the nuclear power plant DCS system Keep consistent with the external clock source, the error is less than 100ms.

[0045] (2) Generate a flashing signal according to the system time;

[0046] The flashing signals of each control station ...

Abstract

The invention, which belongs to the technical field of the DCS control, particularly relates to a light plate scintillation synchronization method applied to a DCS system of a nuclear power plant. With the method, the control and display demands of the BUP of the DCS system of the nuclear power plant can be satisfied; and with system time provided by a DCS clock synchronization system, a unified scintillation signal source is generated, thereby realizing scintillation synchronization of the light plate. The method comprises: (1), obtaining system time; (2), according to the system time, generating a scintillation signal; and (3), invoking the scintillation signal generated in the (2) in a light plate control module; to be specific, calculating an output of control in the light plate control module based on an input of control of the light plate control module. According to the invention, when the method is applied to a DCS system of a nuclear power plant with 100 control stations, scintillation synchronization of the BUP light plate of the main control chamber is realized; the previous-later difference of scintillation can not be identified by naked eyes; neat and beautiful effects are realized; and a visual fatigue is avoided.

Description

technical field [0001] The invention belongs to the technical field of DCS control, and in particular relates to a method for controlling a flickering synchronous flying light plate used in a DCS system of a nuclear power plant. Background technique [0002] At present, the nuclear power plant control system generally uses a digital instrument control platform based on DCS. The main control room uses the full-featured operator workstation based on the computer information and control system (IIC) as the main control method, supplemented by the backup disk (BUP) based on conventional technology as a diversified backup for IIC failure. The optical plate is located in the alarm area on the upper part of the BUP. It is used to indicate the process failure or equipment status, which is convenient for the operator to quickly check and remind the operator to perform necessary operations on the event. It is an important signal for the operator to monitor the operation of the power p...
