基于CPLD的电梯控制器的设计与实现

Design and Realization of the Elevator Controller Based on CPLD

针对传统单片机设计的电梯控制器外围电路复杂、性能不稳定的缺点,提出了基于CPLD的电梯控制器设计。介绍了基于CPLD的电梯控制器的总体设计方案,描述了其内部功能模块的工作原理,利用硬件描述语言VHDL设计出6层楼的电梯控制器,在Max+PlusⅡ集成软件环境中进行编译、仿真、调试及综合,并下载到芯片中以实现其功能。

Given that the traditional single-chip microcomputer-based elevator controller has such defects as complex peripheral circuits and instable performance, a new CPLD-based elevator controller is designed. The implementation method for the elevator controlier based on CPLD is introduced. The principle of the internal function modules is described. A six-floor elevator controller is designed in hardware description language VHDL. The editing, simulation, debugging and combination of the programs are performed in the integrated software environment, Max ＋ PlusⅡ, and the program codes are downloaded to the chip to implement its functions.
