摘　　要：针对农药残毒传统检测系统体积大、灵敏度差和检测速度较慢等问题,设计出一种基于"光转化—化学发光法"的农药残毒快速检测智能化系统。介绍了系统的整体结构、功能以及软硬件实现。系统将农药残毒的浓度转化为光强,进而转化为电压,通过微处理器的A/D转换等实现检测与显示。与目前常用的气相色谱、液相色谱等离线检测技术相比,该系统可以对多种常见农药的种类和溶度实现快速的在线检测,是一种全新的检测方法。Considering that the problem of the big volume of pesticide residues detection and poor sensitivity,and the slow detection speed,we design a type of intelligent system for pesticide residues rapid detection named ＂light conversion-chemiluminescence＂.This paper mainly describes the realization on the structure of the system,function,software and hardware.The pesticide residue concentrations into light intensity,and then converted to voltage,via the microprocessor A/D conversion to realize the detection and display.Compared wit the GC and liquid chromatography detection technology common used,the system can detect common type and solubility of pesticide,and it’s a intelligent,clean and effective detection.
