Portable Pesticide Detector Using Quantum Effect Photon Multipliers and Data Fusion Divisions Based on Chemiluminescence

摘要

This paper provides a portable pesticide detector design and utilizes thedata fusion algorithm in full details. The chemiluminescence detection is based on theproduction of light observed from the agent been donated energy from the degeneratedmolecules of the pesticide that is excited by untraviolet light, in another word, this is anindirect chemiluminescence approach. A quantum effect photomultiplier tube is used toamplify the light. To remove the uncertain quantum noise mainly from the tube, a selfweightedfusion method is proposed. The division method for calculation is simple andfits well with the embedded design and the quantum effect high gain device selected.This meets the system's requirement of limited data processing power drawn from thelight weight battery. The experimental datum processed has shown that the methodworks well, providing the accuracy needed for the low concentration detection of themost commonly used chlorobenzene based pesticides in the Jiangsu province of China.
