基于FSM的电梯控制系统的设计

Design of elevator control system based on FSM

随着我国城市化进程的不断加快,鳞次栉比的高层建筑对电梯的需求量激增。电梯作为高层楼宇中垂直运输人和货物的机电设备,安全快捷运行是极其重要的任务。建立基于有限状态机的双梯并联控制模型,利用Verilog_HDL语言对双梯控制、信号请求、状态显示等3个模块进行软件编程,通过编译和仿真,证明达到电梯的安全快捷的要求。由于采用CPLD器件,使得开发周期缩短、成本降低、设计方便,极大地提高电梯运行的效率和可靠性。

Along with urbanization in our country,the demand of elevator for high-rise buildings increases.The safety and convenient of elevators are extremely important,as the mechanical and electrical equipment for vertical transportation of people and goods in high-rise buildings.This paper establishes a double ladder parallel control model based on finite state machine.To program the function of the double ladder controlling and signal request and status display this paper uses the Verilog_HDL language.Through compiling and simulation,it is proved to achieve the safety and quick lift requirements.Because of the employment of CPLD device in this design,the development cycle is shortened,the cost is reduced,and the convenience of design is improved,as well as the efficiency and reliability of the elevator operation.
