Design And Implementation Of Chemical Laboratory Computer Process Control Systems

Computer information technology from the 1980 s into the petrochemical industry,run research design,process,production control,planning optimization,supply chain optimization applications important advances,business decision-making and other aspects have made,expect this effect will continue to deepen the development of down.Advanced process control(APC)and computer network technology in the petrochemical business in operation,you can transfer the entire chemical data and images in real time;breakthrough simulation technology to more accurately describe the process,to achieve full plant optimization,and optimization will extend throughout the enterprise.The rapid development of computer network and today,for that information management is an urgent need for an effective system to carry out maintenance operations,improve efficiency in the use of laboratory equipment.This laboratory assistants and managers are essential school equipment.Part of students' daily curriculum through visual experiments into language show,laboratory facilities in order to achieve better,faster,more accurate management.How to manage the experimental device through a network and computer software systems,want to do in this regard must be familiar with the equipment it works to solve difficult problems and critical data links and equipment for processing,laboratory work from reality,in this under prerequisite you need a reasonable and feasible to complete the software system needs a comprehensive status quo because of the above-mentioned aspects can be seen in the experimental process more tedious data collection and graphing work,so there is an urgent need to develop a network-based research has standardized,integrated chemical process modern computer control system.Let laboratory assistants and students freed from the complex and lengthy work,improve teaching quality,lower test loss.In order to make the experiment teaching with modern chemical process closely integrated computer control system,the paper school students' ability to observe ability,comprehensive analysis and problem solving skills to analyze student test survey,only by understanding the students in their daily learning process in the short board,and analyzed in order to clear experimental teaching focus,purpose of process control experiment course design.Chemical plant in an actual chemical unit operations,completed the main process equipment design,selection and design of ancillary equipment,the main equipment of the total figure drawing.On the other hand in order to achieve the needs for development.For the development of language has also been ranked excellent handling,the development of this system is used in SQL Server2000,its function within the system source code is done directly.ASP.NET can be written in different languages,including C ++ and Java.When a browser requests a file ASP.NET,ASP.NET engine reads the file,compile and execute the script file,and then return results as plain HTML to the browser.We only need to press a process control system requires an input to operate.This facilitates the developer of reusable requirements.
