摘　　要：目前,常见的物流分拣旋转车昆道是通过减速齿轮和同步皮带驱动滚筒,从而驱动整条传送皮带。为提高系统效率,本文采用外转子无刷直流电机取代传统的旋转辐道,并采用RS-485串行总线设计主从控制系统,实现多从站的控制。进而,以MODBUS-RTU通讯协议设计控制系统通讯,实现多工况控制和多数据传输的功能。At present,the common logistics sorting rotary roller table drives the drum through reduction gear and synchro nous belt,so as to drive the whole conveyor elt.In order to improve the system efficiency,this paper uses the external rotor brushless DC motor to replace the traditional rotating roller table,and uses RS-485 serial bus to design the master-slave control system to realize the control of multiple slave stations.Then,the communication of control system is designed with MODBUS-RTU communicmtion protocol to realize the functions of multi working condition control and multi data transmission.
