基于EDA的电梯控制系统设计(FPGA).docVIP

【摘要】 随着科技的迅速的发展，电梯已经成为生活中不可缺少的交通工具，电梯在国内的需求量也是与日俱增。然而相比于其他发达国家比如欧美，我国的创新元素还还相对较少。电梯的出现要追溯到上世纪，在那时电梯就已经融入到生活中并且取得了使用者的青睐。电梯的传统控制系统通常是采用继电器--接触器，而随着超大规模集成电路技术的成熟，FPGA作为一个新的生力军，在电梯的控制中已经取得了广泛的应用。另外，随着可持续发展理念的深入人心，电梯更是融入了节能的元素。 由于FPGA内部集成了数以万计的逻辑单元，这样的特点使得它在电梯的控制上具有天然的优势。本设计是基于VHDL硬件描述语言而实现的多层电梯控制与远程监控系统，在程序的设计上，主要采用了有限状态机，程序中设立了两个进程相辅相成，以信号灯控制进程作为辅助进程，状态机作为主要进城。 本次设计是采用VHDL硬件描述语言而设计的十层电梯控制系统，以Altera公司的QUARTUS II软件作为开发平台，实现了电梯的基本功能以及远程监控功能。 【关键词】：电梯控制器，VHDL，状态机，远程监控 ABSTRACT Along with the science and technology?rapid development,?the elevator?has become indispensable in life?traffic?tools,?the elevator is also?grow with each passing day?in?domestic demand.?However,?compared to other?developed countries?such as?Europe and the United States,?innovation?elements in China?is?still?relatively small.
