Automated instrumentation plays a very important role in modern industrial production, the instrumentation choose good or bad is one of the important indicators to measure the level of automation. For a qualified automation process engineers, not only need to have the ability to input and output characteristics of various types of instrumentation and failure analysis, also need to master the instrument instrument selection technology. However, teaching some theory of the the domestic automation process engineers deviate from the actual, many process engineers do not have the ability to combine the instrumentation theoretical research and practical work. In order to better solve the above problems, the present study, we used automated instrumentation mechanism analysis and dynamic simulation modeling, while collecting the major domestic manufacturers Automation Instrumentation parameters, to establish a more comprehensive automated instrumentation products database, prepared The instrument automatic selection software. Research automated instrumentation including regulating valves, pressure sensors, temperature sensors, flow sensors, and the level sensor. The subject specific research content and research results are as follows: 1) the mechanism of the commonly used automated instrumentation analysis and dynamic simulation modeling work, including modeling purposes, the idea of ??modeling and simulation analysis, modeling studies on the mechanism for mechanism built the mold four aspects; 2) instrument simulation using the C programming language, the program fast response, good portability. Builder mode this topic are to take the design mode, UML design based on the mathematical model of the established model, including use case analysis, timing diagrams, and design diagram three content; 3) to collect the major domestic manufacturers partially automated meter of product data, establish a database of products and provide product search, add and delete information functions; 4) With the idea of ??virtual instrument interface instrumentation and curve to achieve, including the normal parameter passing, curve output, instrument custom valve failure analysis links ; 5) preparation the instrument automatic selection of software, the the instrument simulation model and product database link. By selecting configurable parameters, the user can be in the same condition to compare different manufacturers of the same type of instrument simulation curve, greatly facilitates the instrumentation selection, improve the work efficiency of the automation process engineers.
