摘　　要：针对选煤厂带式输送机实时运行情况,开发了一种由变频器,执行电动机,控制装置以及负载电流检测等组成的智能调速系统。该系统不仅能实现带式输送机的软起动、软停车,而且能对带式输送机实时变频调速控制,在很大程度上降低了电能消耗,减少了设备的机械磨损,提高了带式输送机的运行安全系数和系统的自动化水平。Aiming at the operation situation of belt conveyor in coal separating plant, the intelligent speed control system is developed, which is made up of frequency converter, motor, control unit and load current detection. This system can not only realize belt conveyor＇s soft start and stop, but also real-time frequency control belt conveyor. This reduces power consumption and mechanical wear of equipment, improves safety factor of belt conveyor and automation level.
