Cold Rolling Backup Roller Bearing Temperature Remote Monitoring Method Based on Wireless Sensor Network


Article Preview

Aiming at the problems, such as difficulties in deployment and immovability during roller changing, which exist in traditional cold rolling backup roller bearing temperature monitoring technologies, a new temperature remote monitoring method based on wireless sensor network (WSN) is proposed. With a structure design of high water resistant and anti-vibration level, the monitoring sensor node can adapt to hot, humid and vibrating working environment. Autonomous power supply and wireless communication facilitate the installation of sensor nodes and bring good movability to sensor nodes. The topologic structure of the WSN is multi-layered and cluster-based. The cluster layer is mesh style, which can guarantee valid data communication while the sensor nodes moving into and out from the network during backup roller changing. Inside a cluster, star style network topology and the time division multiple access (TDMA) communication protocol are used to reduce node energy consumption and to prolong the network life. Remote communication between WSN and enterprise local area network is realized through a multi-hop relay tactic. Practical application in industrial fields shows that the proposed method is efficient to deal with the harsh and complicated operation environment, which is of great significance to monitoring bearing working condition accurately and in time.
