基于CPLD的电梯编码器信号处理

Signal Processing for Encoder of Elevator Based on CPLD

提出以CPLD作为处理器的协处理单元,处理电梯编码器信号的设计方案。CPLD以总线扩展方式来实现与处理器的通信。经软件仿真和现场测试证明,该方案能很好地处理电梯编码器信号。

This paper proposed a design scheme that CPLD as a coprocessing unit of the Processor, processing the signal of elevator encoder. Comunication between CPLD and processor is realized by the way of bus extention. The scheme is proved to handle well the signal of elevator encoder through running in simulation and practice.
