Design of a wireless portable vibration acquisition and analysis instrument

In this paper, we propose a new approach for the design of a wireless portable vibration acquisition and analysis instrument. The system can achieve high-speed synchronous data acquisition at the sample speed of 10k samples per second per channel. The system employs Wireless LAN technology to achieve data transmission to 54 Mbps. A remote signal analysis scheme based on an embedded system is proposed, which is achieved via the wireless connection between the on-line monitoring diagnosis system and the portable instrument. A novel curve display module with two-finger touching zooming technique is employed. The user interface operates under the Windows CE embedded operation system
