Design of Flow Control System on .Sprayer
This paper presents an on-line flow control system for variable rate spray based on Lab VIEW. To solve the control problem of micro-flow or low flow on pesticide in the course of variable rate spraying, a variable rate control system was developed with a NI DAQ, a flow meter, an electronic control injector of vehicle, etc. The characteristics of the flow control system, such as development platform, fuzzy control, PID algorithm, PWM, temperature property, response speed and so on verify that it is much better than that of traditional architecture exploitured by single chip, and it is good linearity between flow of the injector and PWM dutyfactor, the flow rate will automatically change with the variation of dutyfactor at the fix frequency. Experimental results show that this flow controls system has an advantage over other control system.
