| Popis: | 92 Apparently the Injection Molding Facilities had been improved with higher speed, electrification, and micro-molding in the recent years. Further more, with the basic function and technical guidepost been kept as they were, the technique of Electro-Hydraulic Servo has been developed toward with simplified structure, higher reliability, and lower production costs. And the Electro-Hydraulic Servo Controller is playing the main role among all. The embedded system has characteristics, such as operating system software of small, special-purpose strong, simplified, high practicability of system of systems, etc., it is exactly the factory and indispensable function of home automation in the future, in addition, as the internet network develop, is it take shape equipment make apparatus control system, person who actuate, and measuring tool, network of ability future to make, make production management and control networking, This stydu is planning to build up a Digital Velocity and Pressure Controller (DVP) with the compatible parameter-setting software in order to reach the goal of high precision and lowering costs. The embedded network of “System On A Chip (SOC)” will be used as the CPU to ensure the functions of immediate operating system, multi-tasks, and multi-threads in order to secure a set of SOC which is with excellent functions in networks and the realization of the relating controls theoretically. This research is going to use such a SOC, the related electronic components of digital and analog converter circuit, and multi-sets of digital proportional-integral-derivative controlling theory, to complete the controller of digital pressure controller.
