The traditional elevator system based on relay largely decreases the reliability and security since the mechanical and electromagic inertia of relay is big In order to ensure the efficiency and reliable securities, the control method of elevator must be changed. The programmable logic controller(PLC),which develops based on sequence logical control, is digital operation electronic device specialized in the industrial application environme nt. PLC possesses fast process speed and high reliability. Therefore, PLC can be able to ensure the elevator run normally, securely and reliably. In addition. The drive method of elevators has replaced the DC velocity modulation with frequency control due to the development of AC frequency control of motors. The frequency control not only satisfies the fort sense of passengers and ensures the stable precision, but also decreases the loss of power, saves resources and reduces expenses. The frequency control method based on PLC is applied to the elevator system, queuing system design on the basis of elevator. Keywords： The programmable logic controller； Variable frequency control； The elevator drive xx 學(xué)院本科畢業(yè)設(shè)計(jì)（論文） 目錄 1 目 錄 摘 要 .......................................................
