The management of production equipment plays a more and more important role in the normal production process, because it will determine the economic efficiency of enterprises and the production capacity. The learning of new device management concept can effectively improve the overall efficiency of the device. In this paper, the combination of theory TOC and OEE index is an innovation to solve the problem of capacity constraints and bottlenecks that exist in factory production management. The advantage of OEE index in calculating the equipment utilization efficiency is integrated into the production plan. Combined with the automatically collect technica of underlying device data l and electronic Kanban application, the electronic Kanban system was designed with advantage of global view, real-time and quantitative,to solve the problem of delayed feedback and the dynamic transfer of bottlenecks.In this paper, the feasibility of new program was verified by the case of factory. According to the combination of TOC theory and OEE index and manual data collection, the bottleneck of production process and the main factors of OEE loss was identified in actual factory experiment that the bottleneck procedure of drill production line was milling groove and that OEE was 60.2%; the most important element of efficiency loss of milling groove was that among all losses of OEE, the loss caused by groove machine’s waiting for material occupied 19.2%, it was proved that the new scheme can help companies to tap the production bottlenecks.Considering low efficiency of artificially collecting analysis data and hysteresis of information, based on existing artificial OEE analysis, artificial data collection was replaced by automatic bottom data collection system which had two cores: field data collection with industrial Ethernet and output node module WAGO750-881. Data analysis and real time display were realized through connecting with electronic billboard software which was developed on basis of MBT configuration on PC end of host computer; at the same time, work efficiency and effect were improved.
