Abstract-In order to solve the problem of mechanical vibration monitoring, a mechanical vibration monitoring system based on wireless sensor network was designed. First, the requirements of the hardware of the wireless rotating mechanical vibration monitoring system were analyzed. The monitoring node and base station node were designed. Then, based on the VisualBasic6.0 development tool, a software for monitoring the vibration of rotating machinery was designed. It had the functions of command control, data waveform display, and network topology display. In the mode of wireless mechanical vibration monitoring, the organization mode of the network, the transmission mode of data and the corresponding packet transmission format were improved. Finally, the reliable transmission of the data was verified. Compared with the traditional cable vibration sensor, the performance of the monitoring system was verified. The results showed that the wireless vibration monitoring system designed in this paper met the requirements for the monitoring of the vibration state of the rotating machinery.

IntroductionWith the development of science and technology, modern industrial equipment has been upgraded, serialized, refined and automated. This has made outstanding contributions to reducing product cost, protecting environmental energy and improving economic efficiency. At the same time, it puts forward higher requirements for the maintainability of rotating machinery. If a large equipment fails, it will have an impact on the whole production line or even the whole factory, and the economic loss is immeasurable. In order to reduce the impact caused by mechanical faults, more and more members of staff began to study the wired monitoring technology for the vibration of rotating machinery. At present, many wire monitoring equipment for rotating machinery vibration has been successfully developed and adopted by modern industries. With years of experiments and improvements, it can basically meet the monitoring needs of the operating conditions of rotating machinery and equipment in a simple environment. Wired connections have the advantage of simultaneous real-time trans-
