Aiming at the problem that Real-Time Application Interface(RTAI) system can only schedule single-type task,this paper proposes a hybrid task scheduler.It supports Constant Bandwidth Server(CBS) schedule policy,associates soft real-time task with CBS server by using Linux Real Time(LXRT) mechanism,and schedules soft real-time task according to server schedule policy.Experimental results show that the scheduler ensures the normal operation of hard real-time tasks,and improves the service level of soft real-time tasks.
