Labview-based control valve performance evaluation system

Abstract

The invention belongs to the technical field of performance evaluation of a control valve system process industry, and develops and designs a control valve performance evaluation system based on NI compactRIO hardware, various sensors and Labview software, wherein the system realizes the online testing and function evaluation of a control valve. The system comprises a testing signal generation module, a data acquisition module, a signal analysis module, a data storage module, a report generation module and a valve parameter module. In addition, the performance index evaluation results of the control valve can be summarized and printed out on one report similar to a physical examination sheet, and the labview-based control valve performance evaluation system can be used for providing reference basis for the factory testing of a valve manufacturing plant, the maintenance detection of a valve maintenance factory, and the daily maintenance of control valve usage customers.

Description

technical field [0001] The invention relates to the field of industrial process control, in particular to a Labview system for evaluating the performance of a control valve system and measuring various index data of the control valve. Background technique [0002] After the control valve is assembled and before delivery, a series of performance tests are carried out to check whether the data indicators of the control valve meet the national standards when it leaves the factory. The testing is mainly divided into factory testing and type testing. [0003] The control valve is the terminal execution part in the industrial process control system. It often works under high temperature / low temperature and high pressure conditions, or is often in direct contact with process media such as corrosion and strong erosion, and its mechanical parts move frequently, which will cause stress damage. Or wear, which is the most prone to failure or performance degradation. Regular maintenance...
