*****************************************************************
When the encoder fails to measure speed, the precision of vector controlled variable frequency speed regulation will be greatly reduced; when the encoder fails, the speed feedback can be independent of the Direct torque control, and even if the encoder fails, its control precision will be only slightly reduced. Because the track laid on the coal gangue heap is paved on the simple sleepers, not only the joints are not well lapped, but also the foundation composed of different sizes of coal gangue is not smooth, the movement of the gangue truck is not stable, easy to cause the rollover accident. With the use of Direct torque control, one can still have a high control accuracy in the case of speed open loop, suitable for the field work environment; the other is in the case of irregular tracks, using the current regulation of the Direct torque control in real time, it can effectively improve the smooth degree of the gangue truck. FX2N-48PLC. . Japan Mitsubishi Corporation's FRN110G11S inverter with DTC function is adopted as the driving device of the frequency conversion speed regulation system in the main circuit. When the coal gangue winch runs, the motor is driven by frequency converter, the power of the motor is 110kW. The motor drives the gangue winch directly by connecting the reducer. Because of the use of Direct torque control, only an electric motor is needed to drive the truck, which saves the differential and Auxiliary Motor, simplifies the mechanical structure and improves the transmission efficiency. The system operates automatically by installing four position sensors, which are lower deceleration, lower deceleration, upper deceleration and upper deceleration, beside the running track to detect the running position signal of the gangue truck and provide the up / down deceleration and stop signal. As the coal gangue pile higher and higher, just need to regularly move up deceleration and upper limit position sensor position.
