Abstract:

A novel data acquisition system with the architecture of both software and hardware is proposed for the rolling bearing acceleration lifetime intensifying test.An analysis of the development of routine design via VC IDE is made.The design procedure of the accurate timing data acquisition is depicted.This scheme achieves the function of timing and automatic data storage by checking the data length in user's cache without any requirements of the interruption sources from users.

Key words: rolling bearing fault diagnosis;data acquisition;AC6622;timing function
