The development of the Mining Hoist Winch electronic control system should evolve toward new equipment for unmanned, networked, remotely controlled and fully automated. The characteristics of mine frequency conversion electronic control are as follows:
1. The main console uses the FX2N PLC as the main control device. It is designed and manufactured in full accordance with the electromagnetic compatibility standards of GB / T17626.
2. Since the control system is controlled by the PLC, the locking control of the main belt conveyor and the front and rear equipment can be easily realized.
3. The main control station detects the conveyor speed in real time, controls the zero speed brake of the conveyor, and automatically brakes to avoid the conveyor rolling, the inverter and the motor overcurrent.
4.Mining Hoist Winch uses the frequency converter to complete the motor start speed regulation, which can realize the smooth start and speed regulation requirements of the belt conveyor, and is in the long-term low-speed operation state (such as transporter, rope detection, tape inspection), with obvious energy saving. effect.
5.Mining Hoist Winch inverter can realize automatic data exchange through network platform, automatically adjust operating parameters, realize dynamic tracking of master-slave motor, and ensure power balance of multiple motors.
6.Mining Hoist Winch system has fault monitoring and reliable fault alarm protection. It has various protection features such as overvoltage, overcurrent, undervoltage, short circuit, grounding and overheating.
7.Mining Hoist Winch has low speed tape detection. The tape speed can be adjusted from 0.2 m / s to VE.
