Abstract :
In this paper the improvement plan has been proposed to deal with such shortcomings exists in ARM9 and μC/OS-II real-time multi-tasking data acquisition system, in which task competition exist, the slow implementation of peripherals, in time update cannot be made. Achieved sampling channel priority dynamic scheduling, real-time parameters acquisition have been set up here. Peripherals operation which constraints of the system performance on the were time optimized, improved the system efficiency, system security, and task synchronous. There briefly illustrated the system frequency limit tests and detail sampling data display on user interface.
