基于SOPC的氨氮含量检测系统的设计
|
摘要
为简化测量过程,并使测量不会引起二次污染,选用氨气敏电极法测量氨氮。利用SOPC技术在FPGA上建立NiosⅡ双处理器系统,在NiosⅡ处理器中通过硬件互斥核组件对共享存储器进行协调。同时建立标准曲线,根据最小二乘法来计算氨氮值。在DE2-115开发板上进行验证,基本能达到要求。
In order to simplify the measurement process,and make sure the measurement not cause secondary pollution,ammonia gas electrode method is chosen to measure ammonia nitrogen.The SOPC technology is used to build Nios Ⅱ dual-processor system in the FPGA.The shared memory was coordinated by hardware mutex components in the Nios Ⅱ processor.At the same time,the standard curve was set up,and the value of ammonia nitrogen was calculated by the least square method.The verification on the DE2-115 development board can basically meet the requirements.
