Abstract: The design of infusion pump software based on multi-task is introduced in this paper. The MQX real-time operating system based on Freescale K60 series MCU is adopted in the design which realizes the multi-task cooperative working mode. The division of the multi-task module, the scheduling way of the task, the interaction way among the task modules, and the realization method of each module are described in detail. This infusion pump has the advantages of good real-time performance and stable performance.
Keywords: MCU; embedded system software; infusion pump; real-time performance
