    摘要:

    采用單片機作為CPU,結合壓力傳感器,、AD采集卡以及伺服電動機,設計了變量配肥施肥控制系統(tǒng),,同時設計了與硬件配套的上位機軟件,用來采集數(shù)據(jù)與發(fā)送命令,,臺架試驗表明,,該系統(tǒng)能實現(xiàn)變量配肥施肥,且結構簡單,,施肥精度達到

    Abstract:

    95%,。The control technique of variable rate fertilization is introduced. Using single chip microcomputer as CPU, a control system of variable rate fertilization was designed, including force sensor, AD data acquisition system and servo-actuator. An assorted software was designed for selecting data and sending commands. Through test-bed experiment and analysis, the system can complete the control of variable rate fertilization, which has a simple structure, stable operation and high , fertilization precision up to 95%.
