| The technology of automatic control plays more and more important role in the many modern fields. We have improved working conditions, the qualities of products and productivity as a result of the extensive application of the technology of automatic control. In the recent years, embedded control system is applied for office automation, consumption, communication, intelligent facility, robot, industry and military domains, particularly in the fields of office automation, consumption, communication it accounts for about more than 90% of share. From spacecrafts airplanes, warships to lathes, televisions, cellphones, applications of embedded control system are very broad.The application of Real-time embedded control system is the emphasis, the technique of computer application is basis, hardware and software can be cut out. There is a pretty strict limit of reliability, cost, volume and energy-consuming. Real-time embedded control system is applied for firm Real-time and responding circumstance.Aiming at direct current servo electromotor, a set of servo experiment system is designed, exploitation flow and process of Real-time embedded control system are advanced, some issues of them are paid much more attention, the satisfied effects are obtained in the real circumstance, these issues include: exploitation of embedded system, analysis of superiority of the exploitation, the exploitation of embedded Linux operation system from kernel customizing and file system cutting out to system starting up is researched, some factors which effect the system's capability are analyzed, the settled Real-time schemes of Linux OS and the arithmetic of preemptive priority scheduling and round-robin scheduling and latest and rapid arithmetic are researched. Particularly characteristics of driver of Linux OS are introduced, the date-collecting card's driver has been written, causes of using MiniGUI are explained, actualizing principles of MiniGUI are studied and the program which actualizes MiniGUI has been compiled. Finally a complete set of Real-time embedded control system is debugged, all kinds of parameters are measured and amended, the causes of difference between real experiment and computer simulation are analyzed. |
