A Novel Vibration Monitoring System Based on Wireless Sensor Networks

Considering the application limitations of traditional vibration monitoring system, wireless vibration monitoring system is more needed especially for large-scale complex equipment, many measuring points, and widely distributed equipment of process industrial. According to the characteristic and demand of wireless sensor networks and vibration monitoring system, a new design method of wireless sensor network node used in equipment vibration condition monitoring was proposed. First of all, a miniature low-power sensor node for wireless vibration monitoring of equipment was developed. Then, a wireless vibration monitoring system based on wireless sensor networks was constructed. Finally, the general scheme of the system, the design ideas of node hardware and software, the strategies of wireless networking and communication as well as the monitoring software of the system are described. The results of experiment showed that the data sampled by wireless vibration monitoring node is correct, the communication of network system is accurate, and the whole system is reliable. The system therefore can be widely used in vibration monitoring of various equipment, particularly useful in electric power, metallurgy, petrochemical and other widely distributed equipments.
