Focus on the difficulty in monitoring the intelligent manufacturing cell level, the backwardness of equipment management methods, and research on intelligent monitoring technology in intelligent manufacturing cell level. Introduce intelligent cell composition and gear on line cell requirement, establish index system of intelligent cell KPI, analysis the key technologies such as real time data collection, monitoring data and so on. Combine the gear on line cell actual location situation, and realize the location of intelligent cell system. The application results show that the technology can realize the digital and intelligent management of gear on line cell, reduce the management and static workload of workshop manager and improve intelligence level of gear online cell.
