摘要
介绍了空间控制器软件外中断-主程序循环查询任务调度、外中断-定时器中断查询任务调度和外中断-串口中断查询任务调度三种任务调度模式,并对三种任务调度模式的适用范围、优缺点进行了对比分析。结合工程实践,采用外中断-串口中断查询任务调度模式,处理多个型号软件任务调度,充分利用软件资源,合理优化软件结构,大大提高了整个软件的响应及时性和资源利用率。
This paper introduces three task scheduling models of the space controller software,which are external interrupt-main program loop query task scheduling,external interrupt-time interrupt query task scheduling and external interrupt-serial port interrupt query task scheduling,and the application scope of three kinds of task scheduling model,the advantages and disadvantages are compared and analyzed. Combined with the engineering practice,the external interrupt-serial port interrupt query task scheduling model is used to process a plurality of types software task scheduling. It makes full use of software resources,reasonably optimizes software structure,and greatly improves the software to respond in time and resource utilization.
