Complement Of Graphical Real-time Control System Design Software(GRTCS)

Real-time control is one of the most important aspects of computer applications in control field. Because of the characters of real-time and multi-task, the implement of real-time algorithm becomes complex and taking time. In the past, the design of real-time control algorithm has always followed the method that first draw the flow chart then write the program word for word. If one wants to amend the programs or adapt the time sequence, that will bring changes to part of the program and even the whole program. This paper studies the Graphical Real-time Control System Design Software (GRTCS), people can design and implement the real-time algorithm based on graphical method with it. The only thing designers should do is draw flow chart with components representing the common objects, such as task interrupt message message box and the common actions between them, the corresponding program will be auto generated ,any amending can be done in the chart and GRTCS will do the change by itself. So GRTCS make the design and implement of real-time algorithm clear and easy.On account of the real-time algorithm's character of multi-task, the key realizing real-time control is good dynamic combination and cooperation between multiple task. Agent technology has characters of self-determination, asynchronous operations, society nature, communication and isomerism ,it will be the most appropriate technology to achieve parallel multitask. This paper also discusses the application of Agent in graphical real-time control system design software, and emphasizes the means of composing Agent with basis components in GRTCS, moreover, this paper presents a method to realize Agent based on Agent coordinator.
