Abstract

The invention discloses an on-line acquisition system and method for vibration monitoring of a measured object. The system comprises a power supply module, a sensor module, a processing module and a wireless Bluetooth module, the sensor module, the processing module and the wireless Bluetooth module are electrically connected with the power supply module respectively; the sensor module comprises a vibration sensing unit and a digital-to-analog conversion unit; the vibration sensor unit is electrically connected with the digital-to-analog conversion unit and the power supply module, the digital-to-analog conversion unit is electrically connected with the processing module, and the processing module is electrically connected with the wireless Bluetooth module; the vibration sensing unit collects the vibration frequency of the monitored object in a preset interval time period; the processing module judges whether the monitored object generates reflection fission or not according to the vibration frequency; the sensor module collects high vibration frequency information; and the processing module wirelessly transmits the high-frequency vibration information to a mobile terminal or a background server through the wireless Bluetooth module. According to the invention, the abnormal vibration of the measured object can be monitored in real time, and the method has the advantages of high accuracy and high transmission speed.

Description

technical field [0001] The invention relates to the technical field of vibration acquisition, in particular to an online acquisition system and method for vibration monitoring of a measured object. Background technique [0002] Objects that generate mechanical vibration, such as motors and elevators, are critical production tools for contemporary enterprises, and the safety and stability of their operation is the guarantee of production efficiency. During the operation of the machine, it will cause spatial vibration in three directions: radial, axial and torsional. These vibrations are the main cause of equipment damage and are also the main parameters for equipment condition monitoring. Most of the existing monitoring systems have low hardware performance or large equipment volume and high cost. The use of wireless sensor networks to monitor mechanical vibration can make up for the shortcomings of traditional wired monitoring systems. Therefore, inventing an online acquis...
