| Abstract: | A new sewage treatment data acquisition system was designed according to the needs and actual situation of small and medium water plant for now.FPGA was used as core control unit,in which Nios Ⅱ softcore processor was customized.This system has function of collecting and outputting both switching value and analog value.It communicates with host computer through SPI bus.Multi-task scheduling was realized by transplanting μC/OSⅡ embedded real-Time operating system.Experimental results show that the system achieves the desired functionality.It has good flexibility and cost-effective. |
