Design of Electrical Control System of Waste Frequency Winch Based on S7-300PLC

In the waste hoist system in our country,most of the old TKD control system are used,equipments ageing,the fault rate is extremely high,the mine safety production is influenced.A electric control system based on Siemens S7-300PLC is designed,and through Ethernet,the field level with communication monitoring center is realized,the intelligent operation of the system is realized.From the field operation,the system has good operation performance,greatly improving production efficiency.
