3.This paper assumes a development project about the application platform of embedded GUI based on ARM MPU and embedded RTOS(Real-time Operation System). The design and debugging of the Hardware circuit based on ARM MPUhas been completed, and the design and application of Software platform has been implemented, including the program of Boot Loader, the portability of uC/OS-II, the program of UART communication, the application of uC/GUI and so on.
9.The objective of this project is to study the dynamic characteristics of 500C Backhoe Loader hydraulic system by means of theory on mechanical vibration and hydraulic control systems using the IBM Continuous System Modeling Program Ⅲ(CSMPⅢ), to investigate means for improving the product and to develop effective methods for modeling similar hydraulic systems.
