    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
