    摘要:

    以久保田NSD8型插秧機(jī)為研究平臺(tái)，在保證現(xiàn)有轉(zhuǎn)向機(jī)構(gòu)可用性的前提下,，設(shè)計(jì)了一種遙控自動(dòng)轉(zhuǎn)向系統(tǒng)。該系統(tǒng)主要由轉(zhuǎn)向執(zhí)行機(jī)構(gòu),、單片機(jī)控制單元、遙控發(fā)送接收裝置,、角度傳感器,、步進(jìn)電動(dòng)機(jī)等部分組成，可實(shí)現(xiàn)插秧機(jī)轉(zhuǎn)向的遙控自動(dòng)控制,。利用該系統(tǒng)進(jìn)行了遙控插秧機(jī)自動(dòng)轉(zhuǎn)向性能測(cè)試試驗(yàn),，通過(guò)檢測(cè)系統(tǒng)獲得的試驗(yàn)數(shù)據(jù)以系統(tǒng)識(shí)別的方法獲得執(zhí)行系統(tǒng)的傳遞函數(shù)，并分析了系統(tǒng)性能,，分析表明該自動(dòng)轉(zhuǎn)向系統(tǒng)可實(shí)現(xiàn)插秧機(jī)整機(jī)遙控操作,。同時(shí)分別進(jìn)行了180°和90°平地轉(zhuǎn)向試驗(yàn)，試驗(yàn)表明自動(dòng)轉(zhuǎn)向系統(tǒng)可以實(shí)現(xiàn)預(yù)定田間工作軌跡轉(zhuǎn)向操作過(guò)程,。

    Abstract:

    In order to improve the transplanter automatic operation level and realize remote automatic control of steering operation, with the Kubota NSD8 rice transplanter as the study platform, and under the condition of guarantee the usability of existing steering mechanism, a kind of remote automatic steering system was designed. The system mainly comprised steering actuator and microcomputer control unit, remote transmitter installation and receiver installation, angle sensor, and stepping motor. The system can realize remote automatic control of rice transplanter steering. Experiment on automatic steering performance of remote transplanter was accomplished by the system, transfer function of the steering actuator system was gained via experimental data and exploiting the way of system identification, and the system performance was analysed. The analysis showed that automatic steering system can provide reliable guarantee for realizing remote rice transplanter. It was tested about 180° and 90° of flat ground steering, test showed that automatic steering system can realize steering operation process of field work track predetermined.
