Based on Chaos Theory equipment condition monitoring application

Calculation of characteristic quantities can generally be completed within a few minutes,[link widoczny dla zalogowanych], you can calculate such a set of sample data is complete,[link widoczny dla zalogowanych], then calculate the vibration of the newly collected data, the specific time interval, as the calculation speed. While this has some lag, but the actual monitoring still has a certain significance. 3 Conclusion In this paper, automobile transmission gear system for example. Chaos Theory and Wavelet full use of each method in condition monitoring and fault diagnosis field advantage,[link widoczny dla zalogowanych], the combination of mechanical system condition monitoring and fault location, the result of calculation is consistent with the experimental results prove the feasibility of the method. At the same time for the practical application of the method to handle large volumes of data and calculation of velocity lag problem, the paper puts forward the corresponding approach applied research in the future this issue can be discussed in depth.
