Design of Intelligent Detection System for Diesel Engine Main Oil Duct Hole Based on S7-300 Control

The main oil channel of diesel engine cylinder block is the channel of lubricating oil, Whether they are smooth directly affects the working performance of diesel engine. This paper designs an intelligent detection system with programmable controller S7-300 as the control core, which mainly uses programmable control technology, photoelectric sensor technology and touch screen technology to complete the detection of cylinder main oil channel hole. The detection time is controlled within 38 s. This paper introduces the system composition and circuit working principle of detection system, and expounds the design scheme of PLC control system with S7-300 as the core. The design improves the detection speed, eliminates the missed inspection and false inspection, and provides the basic guarantee for the diesel engine to serve industry and agriculture efficiently.
