Mine Hoist Control System Design

The mine elevator is intituled as the throat of mine, and it is the most vital equipment in mine. The elevator change along with distance and energy, and the characteristic of electric power drive is very complex. The electromotor move frequently positive and negative, and always run pass load, and electromotion and apply the brake transform continually. The safety and security is the most vital to elevator. So, the security is the key to elevator. Along with the development and application of computer and programmable logical controller, the controller of mine elevator come forth new visage, the level of automatization and safety and security arrived at the new altitude, and provided a new and modern manage and monitor means.In the design of control system of mine elevator the new PLC control technique at home and abroad are applied to instead of the relay and touch. The advanced digital direct current frequency conversion equipment is adopted in the electromotor transmission. The multifunction digital depth indicator based on DSP is applied to instead of mechanical instrument. Advanced industry control computer are used to monitor and manage the course of elevator.Local debugging and running result indicate that the system is credible,the precision of control is high,and can fulfil the require of the local manufacture.
