摘　　要：水环境智能分析仪可以检测出水环境中的某些离子的浓度,而水环境中某些离子的浓度对工业、农业以及人们的身体健康有着宝贵的参考价值。由于传统的水环境离子的检测方法有很多不足,本文结合了实际的项目,采用了先进的离子选择电极测量法来得到原始的传感器信号,然后经过调理电路,最终传感信号到达控制板。通过控制板的计算和处理,可以得到被测液某些离子的浓度。通过本文设计的测控系统,可以得到可靠、准确的水环境中某些离子的浓度,这为后续的研究提供很好的依据。Water environment intelligent analyzer can detect the concentration of certain ion in water environment However, the concentration of certain ion in water environment has a valuable reference value, which is important to industry, agriculture and our health. The traditional water ion detection methods have many shortcomings. Combined with the actual project, this paper uses the dvanced ion selective electrode measurement method to obtain the original sensor signal , then after a conditioning circuit, eventually sensing signal reaching control board. Through the control panel processing and calculating, we can get some ion concentration of solution. This paper introduces the measurement and control system, which can obtain the reliable and accurate concentration of certain ion in water environment. The follow-up studies provide good basis
