Abstract: This paper analyzes several reasons which bring on timing-errors in real-time system, and proposes different monitor methods according to each reason. It analyzes timing errors on PF power control system to find out some key factors affecting the time performance. Experimental results show that those methods offered to handling timing errors in real-time system can work successfully and availably.

Key words: real-time system, timing errors, process event flow graph, QNX operating system
