摘要
研究了能够同时对多路光电编码器脉冲信号进行细分、计数以及传输的数据采集处理系统。提出了以高度集成的FPGA芯片为核心的设计方式,实现6路光电编码器信号的同步实时处理。坐标测量仪的6个编码器传出的数据完全在FPGA芯片中进行细分、辨向、计数以及锁存传输处理,最后所得的数据以串行通讯的方式传送到PC机。设定了FP-GA芯片外围电路和PC机数据接收程序的功能。
The system of signal acquisition of the four fold-frequency subdivision, direction-judgment, counting and flip-latch of the data which came from the six encorders was investigated. The high-compositive FPGA （filed programmable gate array） chip was used as the core to deal with the signal of the six encoders in real time. The four fold-frequency subdivision, direction-judg- ment, counting and flip-latch of the data which came from the six encorders were totally transacted in the FPGA chip. The final data were sent to the PC through the serial interface of the FPGA. After that, the hardware circuits, especially some of the key parts, were described in detail.
