摘要:

設(shè)計了基于農(nóng)藥光透性的混藥比檢測單元、采用PWM波占空比控制注入量的藥液注入單元和以MSP430F149單片機為核心的低功耗控制單元，分別對各功能單元進行性能測試和標定實驗，在此基礎(chǔ)上構(gòu)建了藥液混藥比反饋在線混藥裝置，并對農(nóng)藥百草枯進行1∶200混藥比定點跟蹤實驗。結(jié)果表明，基于農(nóng)藥光透性的混藥比反饋在線混藥方法及裝置可以實時獲取混藥比反饋信息，自動調(diào)節(jié)藥液注入量，準確跟蹤設(shè)定混藥比，有效滿足農(nóng)藥在線自動混藥要求。

Abstract:

A pesticide mixing ratio detection unit based on light permeability of pesticides, a pesticide injection device controlled by PWM duty cycleand a low power consumption control unit based on single chip microcomputer MSP430F149 were designed. A performance test and a calibrating experiment were conducted for each unit. An online pesticide mixer with mixing ratio feedback was constructed and a fixed-point tracking experiment on the Paraquat SL mixing pesticide and water by 1∶200 was conducted. The result showed that the online pesticide mixer developed by the method of online mixing pesticide with mixing ratio feedback based on light permeability of pesticides could acquire mixing ratio information in time, automatically adjust injection volume of pesticides, accurately track the set of mixing ratio, and effectively meet the requirement of online mixing pesticides. 
