Research on wireless sensor network for mechanical vibration monitoring

Abstract

The mechanical vibration monitoring system based on the cable connection has characteristics such as the complexity of the cabling layout, high cost and poor maintainability and system flexibility. This paper introduces wireless sensor network (WSN) into the mechanical vibration monitoring. The monitoring data transmission in the wireless sensor network is completed by radio waves. There are significant advantages that low cost, remote monitoring, facilitates the diagnosis and maintenance. The multi-hop function and topological flexibility of WSN can effectively avoid wireless signal attenuation effect of buildings and equipment. This paper presents a wireless sensor network model for the mechanical vibration monitoring, analyses the two kinds of wireless sensor network topology, and sets up a vibration sensor monitoring network system. The system takes vehicle vibration sensors to collect monitoring data, and combines the ADTCP algorithm for multi-hops network, puts forward a scheme that limits the congestion window to reduce the network congestion. In this paper, the scheme can effectively alleviate the sink node's congestion in the mechanical vibration monitoring wireless sensor network, and improve the performance of network monitoring.
