[Abstract]:In the process of modern industrial production, monitoring the condition of equipment is an important prerequisite to ensure the safe operation of mechanical equipment, and has extremely important safety significance and economic value. With the rapid development of computer and Internet of things, the deployment of wireless sensor networks to monitor the vibration of equipment is a new developing direction of state monitoring technology, which has important research significance and development potential. In this paper, the wireless vibration monitoring network system based on ZigBee is designed according to the requirements of wireless sensor network technology and mechanical equipment condition monitoring. The following research work is carried out: first, the development and application requirements of mechanical equipment vibration monitoring technology are analyzed. The overall structure of wireless vibration monitoring network is determined. The network system is divided into two functional modules: acceleration acquisition node and wireless network gateway. Secondly, the software structure and hardware structure of monitoring network are designed. The acceleration node takes CC2530F256 as the core, the gateway takes the ARM9 processor as the core to carry on the modularization software and the hardware design. The node completes vibration acceleration signal acquisition and wireless upload. As a network coordinator, the gateway includes network management, data analysis and processing, data management, data communication and other functional modules. Thirdly, the commonly used equipment fault diagnosis indexes are studied and analyzed, and the time-domain and frequency-domain characteristic data of vibration signals are obtained by using time-domain and frequency-domain algorithms on the network gateway. The gateway supports Ethernet, Wi-Fi and RS-485 data communication. It can access the network through browser, mobile terminal APP and so on, and realize flexible and convenient state monitoring. The wireless vibration monitoring network designed in this paper has the characteristics of reliable data collection, convenient deployment, flexible communication and low input cost. It can meet the needs of mechanical equipment vibration monitoring.
