Research on Coal Flow Control Method of Conveyor Based on Ultrasonic Sensor
In order to solve the shortcomings of low automation degree and high operation cost of conveyor coal flow control,a new ultrasonic sensor-based conveyor coal flow control method is proposed.Firstly,the conveyor running speed is dynamically monitored by the belt speed sensor,and the coal quantity is analyzed by the ultrasonic sensor,then the coal flow is accurately calculated by the dynamic time window algorithm when the conveyor is running,and finally the flexible adjustment of the conveyor running speed is realized by the frequency conversion speed control mode.According to the practical application,the new coal flow control technology has a 2％deviation of coal quantity monitoring,which can realize the automatic matching of coal quantity and belt speed,and reduce the energy consumption of conveyor operation by 53.17％.
