The Main Fan-based Plc Control Automatic Monitoring System Design

Traditional main fan monitoring system of data cannot be handled in time, to protect the equipment safe reliable, efficient economic operation, improve large equipment operation control automation management level and reduce operation personnel and post type of discrete, for the next step to achieve production process of centralized monitoring control, this paper use models Siemens S7-300 PLC design mine main fan automatic monitoring and controlling system. The system through testing the fan department of various sensors and field of mine main fan parameters measurement method, the paper realize mine ventilator performance and state and motor electric parameters monitor, and can through communication system to achieve remote control.The system of the main fan equipment solution of automatic monitoring, powerful guarantee for ventilation safe, efficient, reliable operation, convenient maintenance and management of equipment and improve the safety of coal production. This system USES PC and machine, the machine adopts PLC as drive inverter and responsible for collection of sensor signals, PC acousto-optic alarm signal by polymerizing-kettle finish, data processing, generating chart etc. Function. In the design of Siemens company to the use of PLC STEP7 programming, configuration, WinCC use computer program written human-machine interface, Rely on realize MPI communication protocol, the communication.
