| Abstract(in English) | A plant monitoring system needs to provide non-stop service.Thus each element of the system is composed of two subsystems,and has standby redundancy.A plant monitoring system is a real-time system, which has timing constraints.In subsystems-switching caused by faults in one of the subsystems,it is needed that contradiction in the behavior of the subsystems must be avoided and timing constraints tasks in the subsystems must be held.In this paper,we propose a method to manage states of tasks in a standbyredundancy system,which is composed of two real-time subsystems based on rate monotonic analysis(RMA).This method provide us with subsystems- switching without contradiction.In addition the timing constraints of the system can be satisfied in the subsystems-switching.We have realized real-time middleware,which is laid on a POSIX 1003.41,.4a compliant operating system.This middleware supports the task management method. |
