Development Of Catalytic Reaction Evaluation Instrument Control Software Based On Eclipse

The variety of catalytic reactions leads to a wide variety of catalytic reaction devices,such as photo-thermal coupling catalysts,fixed-bed catalysts,etc.At the same time,the cost of configuring different softwares for different devices is relatively high,so the current domestic catalytic reaction evaluation devices are often manual,time-consuming and unintuitive.In recent years,with the rapid development of industry,supervisory control and data acquisition(SCADA)has been favored by everyone because it can quickly build a field industrial environment through graphical editing,real-time multi-task,and adapt to a variety of hardware.It can be seen that the development of a catalytic reaction evaluation device software which is simple to use,intuitive to display,complete in function,adaptable to various anti-reflex devices,and similar to SCADA is imminent.This paper presents an implementation of catalytic reaction evaluation device control software based on Eclipse.The system uses Eclipse's most distinctive plug-in technology and graphical modeling framework.The graphical modeling framework(GMF)generates code that allows developers to focus more on the design of business logic and improve the efficiency of software development.The use of plug-in technology is divided into functional modules to make the software easier to be extended and maintained.The software implements five function modules:flowchart editing,user management,instrument control,data management,and multitasking.Flowchart editing is divided into two types:engineer mode and user mode.The engineer uses the drag and drop method to complete the drawing of the entire device flow chart and configures it briefly;the user can only use the experimental flow chart to control the instrument.The user management module,depending on the user's permissions,will load different functional modules.The instrument control module uses the serial port communication to realize the control of multiple temperature devices,pressure devices,mass flow meters,pumps,etc.,and uses the polling method to obtain the data of each instrument.The data management module includes the use of SQLite database to save data,and the collected instrument data is displayed in a graph.Multitasking is the editing of the experimental flow through the form,and the automatic control of the instrument according to the experimental flow is very convenient for the experimental operator.The catalytic reaction evaluation device control software,firstly,performs a requirement analysis.Then based on the requirement analysis,it designs the software system framework and the detailed functions of the functional modules.Secondly,based on the graphical modeling framework,each function module is developed according to the plug-in approach.Finally,the achievements of the five functional modules in this software are demonstrated.
