    摘要:

    采用單片機(jī)作為CPU，結(jié)合壓力傳感器、AD采集卡以及伺服電動(dòng)機(jī)，設(shè)計(jì)了變量配肥施肥控制系統(tǒng)，同時(shí)設(shè)計(jì)了與硬件配套的上位機(jī)軟件，用來(lái)采集數(shù)據(jù)與發(fā)送命令，臺(tái)架試驗(yàn)表明，該系統(tǒng)能實(shí)現(xiàn)變量配肥施肥，且結(jié)構(gòu)簡(jiǎn)單，施肥精度達(dá)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%.
