Design of multi-parameter water quality monitoring instrument based on ARM + FPGA

针对现有水质监测仪测量参数相对单一、实时性差、测量准确度低等问题,设计了一种基于ARM+FPGA的多参数测量的水质实时监测仪.该设计采用ARM与FPGA相结合的方法、利用FPGA的并行工作方式,同时对水质进行多路信号采集及存储,然后通过ARM处理器进行处理分析.测试结果表明,该设计测量精度高,实时性好,性能稳定可靠,各项测量指标均能够达到设计要求.

Aiming at the problems that the existing water quality monitoring instrument measurement parameters are relatively single,poor real-time,low accuracy of measurement degree,a multi-parameter water quality real-time monitor instrument was designed based on ARM ＋ FPGA. Adopting the method of multiplexed signal acquisition and storage on water quality. This instrument used the parallel working mode of FPGA to conduct,and processed by the ARM processor. The experimental results showed that： the water quality monitor parameters had high measurement accuracy,good real-time,stable and reliable performance,the measurement indexes could meet the design requirements.
