Roller is a key component of milling machine in iron and steel industry, with the development of industrial wireless technology. The online predictive maintenance of the roller plays an important role in effective production. But the harsh working environment - spray of cooling liquid, moving, high temperature and heavy shelter - cause low quality of wireless communication and need high reliability. The paper proposed a novel roller monitoring system based on star/mesh topology, which use 2.4 GHz in mesh subnet and 433 MHz in star subnet to avoid interference between nodes in large scale networks. The paper designed a self-organized multi-channel link layer protocol optimized network flexibility and power consumption under high reliability. The system was deployed in the real iron and steel plant to monitor support roller of strip mill with one years, which shown a high reliability and low power consumption, and improved the efficiency of the roller maintenance.
