Abstract
The invention discloses a sound monitor generating system and method based on a property sequence chart. The property sequence chart is used for describing behavior of a known system and obtaining a game structure corresponding to the known system and eventually, sound monitors which correspond to components participating in interaction with a system and the environment respectively are obtained and used for monitoring the known system. Thus, the aim of preventing the system from failing is achieved. A property sequence chart editer provides a completely graphical window for a user to draw out interaction in the system. The property sequence chart is converted into a rule (standard) of the game structure and converted into the game structure according to the rule. A game structure window displays the game structure generated by the property sequence chart. The game structure is converted into a rule (standard) of the sound monitors. The game structure generates multiple sound monitors according to the rule. A monitor window is used for displaying all the sound monitors. According to the sound monitor generating system and method based on the property sequence chart, monitoring results with more details are obtained according to the features of multiple-valued semantics possessed by the game structure and needed information is provided for stopping and recovering failure.

Many-valued semantic it is provided that more detailed monitored results and provide required information to stop to realize and recover to lose efficacy.And from
Motivation typically only has two values of true and false.The state of game structure and message can be divided into system controlled and environment respectively
Controlled.The state of the game structure generating herein, according to system or environment, controlled or uncontrollable, can be divided into 7 classes to solve
Release the semanteme of psc: meet, infinitely controlled, system limited steerable, system emergency are controlled, environment limited steerable, environment are promptly controlled
And break rules.
Aspect oriented programming(Aspect-oriented programming) can be by precompile mode and run duration
Dynamic proxy is realized dynamically adding function to program in the case of not changing source code.Aop code is exactly previously mentioned
" watch-dog ", generates aop code according to gs, and the present invention can not make any modification to original system code using aop technology
On the premise of watch-dog is added to each assembly or service, this watch-dog can capture internal system and internal system with outer
Whether " legal " information exchange between portion's environment, judge the behavior of system, thus reaching monitoring during the operation to whole system
Even the failure behaviour of system is made prediction, stops and recovered.
