A dcs equipment diagnosis method with fault warning function

Abstract

The invention belongs to the technical field of industrial control, and particularly relates to a nuclear power DCS equipment diagnosis method with a fault early warning function. The method comprisesthe following steps: (1) defining faults according to grades and layers; (2) when diagnostic software is started, carrying out importing operation on a system; (3) after a system architecture diagramis successfully imported, displaying all control station information in the system by a main interface of equipment diagnosis software; and (4) after all control stations of the system and all equipment information under the control stations are imported, selecting different communication modes by the software according to current operation modules of the control stations. The equipment diagnosissystem provided in the invention not only provides a fault alarm function, but also is convenient for engineering personnel to quickly and accurately position fault information in a system debuggingstage. In the invention, a defect of a traditional DCS control system in an aspect of equipment fault diagnosis is overcome, and when a fault occurs, fault diagnosis information can be accurately andtimely transmitted to an operator and a maintainer through an alarm indication mechanism.

Description

technical field [0001] The invention belongs to the technical field of industrial control, and in particular relates to a diagnostic method for nuclear power DCS equipment with a fault early warning function. Background technique [0002] Industrial DCS control systems are used in various industries such as chemical industry, electric power, and nuclear power. At present, the DCS control system is mainly composed of: an integrated automation system composed of engineer station, operator station, field control station, communication control station and data server. Functionality of a medium-sized distributed control system. [0003] At present, the fault diagnosis of the DCS control system is mainly displayed on the operator station and engineer station. Once a certain device fails, an alarm message will be generated on the operator station and engineer station to remind the user that the device is faulty. The display form on the operator station and engineer station is to d...

[0005] The equipment fault diagnosis function in the traditional DCS control system is far from meeting the needs of the nuclear power instrumentation and control system for the fault diagnosis system. Therefore, the present invention proposes a nuclear power DCS equipment diagnostic system with a fault early warning function. The equipment diagnosis proposed in the present invention The system diagnoses the failure information of different equipment in different levels; displays the severity of the failure in different levels; archives all the failure information; obtains the probability of equipment failure according to the archived failure information, so as to provide data support for the regular test of the instrument control system; Cause Analysis Diagram of Fault Information
