Vibration monitoring node with functions of wire communication and wireless networking

Abstract

The invention relates to a vibration monitoring node with functions of wire communication and wireless networking. The existing vibration monitoring technology lacks an effective transmission mode so that only a node or only several nodes can be subjected to vibration monitoring. The vibration monitoring node is characterized in that a wireless Zigbee communication module has signal connections respectively with an acceleration sensing module, a JTAG download module, a serial communication module and a radio frequency antenna module; and a power supply circuit has electric connections respectively with the wireless Zigbee communication module, the acceleration sensing module, and the serial communication module. The vibration monitoring node adopts a wireless Zigbee communication technology and thus the vibration monitoring node has a wireless networking function. Through the multiple vibration monitoring nodes, data interaction or data relay is realized so that use convenience is improved under the premise that a communication distance is guaranteed.

Description

Therefore, vibration monitoring technology is of great significance in the industrial field. In broadband vibration measurement, acceleration sensors are widely used at present, but the current vibration detection technology lacks ...

AI Technical Summary

Problems solved by technology

In broadband vibration measurement, acceleration sensors are widely used at present, but the current vibration detection technology lacks effective transmission methods, and vibration detection is often limited to a certain point or a few points

The vibration measurement data of a limited number of points in various facilities often cannot make a comprehensive measurement of the vibration of the facility
