- Abstract
In order to improve the mixing ratio of online pesticide mixing system, and control the flow of pesticide in the system. Jet-mixing method was adopted, Structure parameters and material of Jet-mixing device were optimal selected, online pesticide mixing system based on PWM variable was designed and built, PWM was used to control the flow of pesticide in the system. Pesticide flow control system based on MCU was designed. For the whole mixing system, the experiment was carried out. As a result, with the pesticide flow control system, mixture ratio of online pesticide mixing system can be improved generally. Under the same frequency, with duty cycle of PWM signals decreased, mixing ratio increased, when the frequency reached 20Hz and duty cycle become 1/10, mixing ratio reaches 193.84, the effect of pesticide flow controlling was best, compared without the control system, mixing ratio was increased by nearly 20 times.
