At first, with the low-frequency data measured, three of the LRE fault detection systems for the real-time condition are proposed using the nonlinear identification technology of the BP neural network, the state estimation technology of the dynamic neural network, and the pattern recognition technology of the fuzzy hypersphere neural network. The learning algorithms of the BP and dynamic neural network are researched at the same time. Furthermore, while the engine operation is divided into the start and steady-state processes, the real time ability, the response time, the accuracy, the robustness, the sensitivity and the monitoring parameter optimization are studied. In the test data analyses of the YF-75 engine, the detection system correctly carried out for all normal tests, and in the three abnormal tests the engine faults were accurately forecasted.

This article analyses the actual reality of network security and briefly intruduces a few of aggressive measures which threaten the safety of network. From these we can see, the passive ways such as firewall and anti-virus software to combat network attack can not meet the increasingly needs of network accessing .As a result, an intrusion detection system must be established to differentiate between the legal accessing and inbreaking attack. That is intrusion detection.
