Open weak signal acquisition system based on authority management
Yonggang Leng · Computer Engineering and Applications Journal · 2009
In the conceive of open equipment administration network,the authority path management is built in order to bring the data safety into effect.The system integrates the weak signal acquisition system and the remote expert diagnosis,which can be regarded as the front-line subsystem of the whole system,providing timely for the plant management section the in-situ equipments operation condition information.In this paper,the scheme of the system is introduced in detail and adopts Concatenation Stochastic Resonance as weak signal acquisition method.The feasibility and efficiency of the proposed system have been demonstrated by its practical application in a certain power plant in Tianjin,China.
