摘　　要：带式输送机是煤矿井下物料运输的关键设备,多机驱动可以实现大运量和高运输效率。采用智能控制方法实现功率平衡,可以确保各个驱动电机协同工作,避免由功率分配不均导致的效率低下。基于上述需求,设计了煤矿井下带式输送机多机驱动功率平衡智能控制系统。该系统涵盖了调度层和控制层,通过RS-232接口和CAN(Controller Area Network,控制器局域网)总线实现数据传输和电机速度控制。通过对电机功率的监测与采集,设计开环控制及应用自适应参数调整模型,系统实现了在最大负载条件下变频器的稳定运行工作,输出电压和电流维持在额定值附近,证实了系统良好的稳定性和可靠性。Belt conveyor is the key equipment for material transportation in coal mine.Multi-machine drive can achieve large volume and high transportation efficiency.Power balance achieved through intelligent control methods can ensure that each drive motor works together to avoid inefficiency caused by uneven power distribution.Based on the above requirements,an intelligent control system for multi-machine drive power balance of underground belt conveyors in coal mines was designed.The system covers scheduling layer and control layer,and realizes data transmission and motor speed control through RS-232 interface and CAN(Controller Area Network)bus.By monitoring and collecting the motor power,designing the open-loop control and applying the adaptive parameter adjustment model,the system realizes the stable operation of the inverter under the maximum load condition,and the output voltage and current are maintained near the rated value,which proves the good stability and reliability of the system.
