Control Design of Automatic Intelligent Car Washing Machine Based on PLC

With the vigorous development of China's auto industry in recent years, car washing has become more and more important.In view of the high cost, low efficiency, low cleanliness, low automation and low water utilization rate of the current car wash industry, this paper designs a fully automatic car washing machine based on S7-200 SMART PLC control system, which is intelligently cleaned.The system can realize all-round high-efficiency cleaning of the vehicle, and the sewage treatment system can realize the recycling and reuse of the car wash water.The system not only improves the efficiency, cleanliness and water resource utilization of the car wash, but also has the advantages of stable system, convenient use and simple maintenance, and has broad market prospect.
