In the modern society, elevator, like cars, steamboats has bee indispensable transportation tool for human beings. There are several control ways, such as relay and PLC control, and so on. The features of PLC control elevator are the following: First, high reliability. The MTBF of PLC can generally reach 30000 to 50000 hours. And it can easily adapt to the environments. That it can work reliably under the industrial environment. Second, easily program. The monly used programming language is ladder diagram language, which is imagic and can be easily mastered. When the working process need to be changed, the program can be changed on spot, which is convenient and flexible. Third, small volume and pact structure and it is easy to install and paper introduces the system structure of a VVVF (variable voltage variable frequency) elevator control system with PLC, we can find the advantage of this control method by pared with others, we achieve its hardware and software design in detail with a idea of module and clarifies that this control mode is feasible. Keywords： PLC。 elevator。 elevator control。 transducer。 ladder diagram 重慶科技學(xué)院高等教育自學(xué)考試本科畢業(yè)論文 目錄 III 目 錄 中文摘要 .................................................................................................
