【Abstract】 This paper describes a vibration data acquisition and detection method using the wireless transmission. The system realizes the wireless transmission of vibration data through Freescale’s MC13192 chip, the detecting terminal gets the vibration signals and achieves the analog-to-digital conversion through the acceleration sensor chip MMA61612Q at the accuracy of 0.01m/s2. The receiving end uses the remote visualization interface to obtain the collected data. The actual test shows that the system can timely and accurately acquire the vibration signals, and has a long distance of data transmission with a good effect of remote terminal monitoring. Furthermore, the low-power design takes the system a wide range of applications.更多还原
