Debugging method of software recovery of DCS control system

Abstract

The invention discloses a debugging method of software recovery of a DCS control system. The method comprises the following steps: (1) installing related software of the DCS control system; (2) downloading a configuration file of the project to a controller; (3) downloading the project software and configuration screen of the project to each terminal; (4) performing main screen check; (5) performing controller program check; (6) performing a network switching test, recording a test result from an operator station or an engineer station screen, and analyzing and solving problems in the test process; (7) performing an analog quantity channel test according to a range sequence, wherein the error should meet related requirements; (8) performing a channel test on a switching value according toturn-on or not, wherein the error should meet related requirements; (9) performing the channel test on an SOE card member by using an SOE signal generator, wherein the error should meet related requirements; and (10) completing the debugging. Through the above specific operations, the debugging method disclosed by the invention ensures the normal operation of the software of the DCS control system.

Description

technical field [0001] The invention belongs to the technical field of DCS control system debugging, and in particular relates to a debugging method for DCS control system software restoration. Background technique [0002] DCS is the English abbreviation of Distributed Control System (Distributed Control System). It is also called Distributed Control System in the domestic automatic control industry. Developed and evolved on the basis of the system, it is a multi-level computer system composed of process control level and process monitoring level with communication network as the link. It integrates 4C technologies such as computer, communication, display and control. Its basic idea is to disperse Control, centralized operation, hierarchical management, flexible configuration and convenient configuration. In the new thermal power generation unit or DCS control system transformation, DCS control system recovery debugging has become an important task, and a mature debugging ...
