摘　　要：为保证带式输送机的稳定运行,提出基于顺煤流启动的带式输送机变频调速节能控制优化方法。利用积分原理分析带式输送机皮带煤量检测装置结构,明确不同传感器的安装位置。使用超声波传感器、速度传感器分别采集带式输送机皮带煤流量、各点带速数据。结合目前煤流量、带速状态,设计基于模糊可编程逻辑控制器(PLC)的输送机变频调速节能优化方法。通过变频电动机调节带式输送机以自动化调节带速,完成带式输送机变频调速节能控制优化。试验结果表明:所提方法在执行带式输送机变频调速节能控制优化操作时,未出现电能浪费和皮带磨损问题。该方法可使带式输送机的启动带速、张力波动幅度明显变小,并使运行稳定性变高。该方法有效解决了电能浪费和皮带磨损等问题,保证了带式输送机顺煤流的稳定运行。To ensure the stable operation of the belt conveyor,the optimization method of frequency conversion speed regulation and energy saving control of the belt conveyor based on downstream coal flow starting is proposed.The integral principle is used to analyze the structure of belt conveyor belt coal flow detection device and clarify the installation position of different sensors.The ultrasonic sensor and speed sensor are used to collect the belt coal flow and each belt speed data of the belt conveyor,respectively.Combined with the current state of coal flow and belt speed,the conveyor frequency conversion speed regulation and energy saving optimization method is designed based on fuzzy programmable logic controller(PLC).The optimization of frequency conversion speed regulation and energy saving control of belt conveyor is completed by adjusting the belt conveyor through the frequency converter motor to automate the adjustment of belt speed.The test results show that the proposed method does not cause power waste and belt wear problems when performing the optimization operation of belt conveyor frequency conversion speed regulation and energy saving control.The method can make the starting belt speed and tension fluctuation of the belt conveyor obviously smaller and make the operation more stable.The method effectively solves the problems of power waste and belt wear,etc.,and ensures the stable operation of the belt conveyor downstream coal flow.
