摘要
针对水质检测的发展以及水资源保护的需求,提出了基于Android设备的便携式水质检测仪器,仪器主要由传感器探头、下位数据采集、存储、处理设备和Android智能设备端组成。结果表明,该仪器对COD和DO的线性检测范围分别为0~60 mg·L^(-1)和4.5~13 mg·L^(-1),且重复性良好,CV值分别为2.20%和1.73%。仪器被成功应用于实际水样的检测中,检测结果基本准确,满足水质检测的技术要求,有一定的参考价值。
This paper proposes a portable water quality detector,based on an Android platform,for detecting and protecting water resources. The instrument mainly comprises a sensor probe,slave computer,and an Android smart device. The experimental results showed that the linear detection ranges of COD and DO were 0 to 60 mg·L^(-1)and 4. 5 to 13 mg·L^(-1),with good repeatability. The CV values of COD and DO were 2. 20% and 1. 73%,respectively. The instrument was successfully applied to detect an actual water sample and the detection ability largely met the technical requirements for water quality detection. Therefore,the instrument can be referred to detect the water quality.
