针对电梯数据采集数目较多和数据处理复杂等特点,提出了基于数字信号处理器(DSP)和现场可编程门阵列(FPGA)的电梯智能数据采集系统。在介绍了系统整体结构及各组成子模块后,给出了模块与器件之间硬件接口设计思路和架构,描述了整个系统的软件框架,设计了DSP、AD采样、网络通信和抗干扰等程序。整个系统在工程应用中易于实现,具有很好的推广价值-n accordance with the characteristic of elevator for the large number of data a

DSP的ADC采样和SCI串口通信，在CCS3.1环境下已成功运行-DSP' s ADC sampling and SCI serial communication, the environment has been successfully running CCS3.1

BF537开发板上用fpga实现AD采样，DSP用DMA将fpga内的数据读回dsp-BF537 development board with fpga implementation AD sampling, DSP DMA will use the data read back fpga dsp
