| Abstract: | Mine hoist is the key transportation equipment between the ground and underground,can realize stepless speed regulation and easy reversion by combining variable frequency speed and PLC.Several security protections were realized by real-time monitoring various operation parameters and states(such as position and velocity of the hoist) with computer.The safety,reliability,control precision and speed performance of the electric control system were improved. |
