Diagnosis system and method of pcs7 software system

Abstract

The invention relates to a diagnostic system and a diagnostic method of a PCS7 (process control system) software system. The diagnostic system of the PCS7 software system comprises a diagnostic information acquiring module, a diagnostic information textuality module, a fault reason analyzing module and a diagnostic report generating module. With the adoption of the technical scheme of the invention, various diagnostic information during the operation of the PCS7 software system can be accurately acquired so that a comprehensive data basis is provided for fault analysis; and moreover, the reason of a fault can be analyzed from the various diagnostic information in time, so that reference for finding a solution is provided, and further, the efficiency of eliminating the operation fault of the system is improved.

Description

technical field [0001] The invention relates to the field of automatic control systems, in particular to a system and method for diagnosing PCS7 software systems. Background technique [0002] Distributed Control System (Distributed Control System, DCS) is a comprehensive control system that emerged with the continuous rise of modern large-scale industrial production automation and the increasingly complex requirements of process control. In order to build a distributed control system and control the operation of the system, a variety of DCS software systems have been developed, and Siemens' PCS7 system is a typical one. [0003] Due to the complexity of the distributed control system, the PCS7 software system consists of a large number of components, which are used to realize various control functions in the distributed control system. The installation and operation of most PCS7 software systems are based on the Microsoft Windows operating system, while the database of the...

Problems solved by technology

The installation and operation of most PCS7 software systems are based on the Microsoft Windows operating system, while the database of the HMI part uses Microsoft SQL Server, because they all have common characteristics such as a wide variety of components, fast version update speed, and close association with the operating system, so in Various failures may occur while running

[0004] Although some components of the PCS7 software system have some diagnostic functions, due to the single and scattered functions, it is often difficult to centrally and accurately reflect the fault information when the system actually fails, and it is difficult to timely and quickly learn from various The fundamental problem of the fault is analyzed in the diagnostic information, which brings great difficulties to effective troubleshooting
