Intelligent system of construction machinery based on μC/OS-II

For the past few years, computer technology, sensor technology and embedded technology are widely used in construction machinery area. These new technology make the construction machinery have some new features, such as low energy cost and high automatization. With the DSP chip TMS320LF2407A of TI, the system is designed to realize special tasks through arithmetic of path plan, which can gather the angle signal of excavator bucket, pole and arm real time and then drive the hydraulic pressure proportion clique according to the planned path. The paper introduces the system design of hardware architecture and PRI of Embedded real-time operating system application mostly. The function of the toy stick is man-machine conversation, which is provided with CAN bus interface. Locale test has proved that it is steady-going and can alleviate the work intension and experiential requirement of manipulator.
