摘要
设计了一个由Siemens S7-300 PLC和英威腾(INVT)CHF100变频器构成的电梯系统。系统中PLC作为核心控制器,实现楼层计数、换速、故障报警、开/关门和平层控制等功能。相比继电器控制,PLC控制提高了系统的可靠性和平层精度。变频器实现曳引电机的无级调速改善了电梯运行时乘客的舒适感。
An elevator system is designed in this paper composed of Siemens S7 300 PLC and INVT transducer.PLC is made as the main controller to realize the functions of the floor counting,the speed change,the malfunction alarm,control of opening or closing the door and braking control.The reliability of system and floor level precision are improved by the PLC system compared the electric relay control system.The Inverter is used for stepless speed regulation of traction motor.The feeling of comfort is improved when elevator running.
