Abstract: A remote monitoring system of rolling bearing using the virtual instrument， database and wireless network technology was developed which has a composite structure based on C/S and B/S structure .The system consists of three parts: data acquisition-side， monitoring and diagnosis-side， and data communication. It can realize the real-time data acquisition and processing， the abnormal data screening and uploading as well as signal analysis and fault diagnosis by the remote users. The life-cycle test of deep groove ball bearing-6309 shows that the system can implement the real-time monitoring of the test bearing and find out the fault's cause and position through further analysis of abnormal data. This system is of pratical value.
Key words: rolling bearing； remote monitoring； fault diagnosis； C/S structure； B/S structure
