摘要：This paper describes a realtime transformation for an existing non realtime process control system. The proposed system combines realtime scheduling with ZigBee wireless communication and Monitoring. This paper implements the effective handling of multiple tasks using RTOS concepts to suit critical applications and concurrent task handling in realtime environment. Priority based preemptive task scheduling algorithm is used to protect shared data and to achieve task synchronization. Thus the reliability and processing ability of the system are improved greatly by adding the �C/OS-II operating system.
