摘　　要：文章介绍了几种常见的操作系统多任务调度算法,针对安防警报的任务特点,提出等待时间的多任务调度算法。该方法保证了高优先级的任务有充足的CPU运行时间,同时也不会让其他任务一直得不到运行而产生饥饿现象,满足安防警报系统任务调度的要求。Several common multi-tasking operating system scheduling algorithms were introduced. For the task characteristics of security alert, the waiting time multi-task scheduling algorithm was presented. The algorithm ensure high-priority tasks have sufficient CPU running time, while it let the other tasks have chance to run without hunger, and meet the requirements of the system task scheduler.
