Abstract：Aiming at the capacity constraint and bottleneck of factory production management，many issues were studied include

monitoring of production bottlenecks and the improvement of production process. The idea of electronic display board system，baesd on

TOC theory，OEE index and electronic display board，was summarized. The electronic display board system of mining production

bottlenecks and the analysis of OEE loss was proposed based on two cores：field data collection with industrial Ethernet and output node

module WAGO750-881.Feasibility of the theory was verified in actual factory experiment，it was found that the bottleneck procedure of

drill production line was milling groove. The results indicate that among the 40%loss of OEE，the loss caused by groove machine's waiting

for material occupied 19.2%，the design of electronic display board system can increase the efficiency of enterprises and the effect of

process improvement.

Key words：theory of constrain（TOC）；overall equipment offectiveness（OEE）；production bottlenecks；electronic billboards
