    摘要:

    以久保田NSD8型插秧機為研究平臺,，在保證現(xiàn)有轉(zhuǎn)向機構(gòu)可用性的前提下，設計了一種遙控自動轉(zhuǎn)向系統(tǒng),。該系統(tǒng)主要由轉(zhuǎn)向執(zhí)行機構(gòu)、單片機控制單元,、遙控發(fā)送接收裝置、角度傳感器,、步進電動機等部分組成,，可實現(xiàn)插秧機轉(zhuǎn)向的遙控自動控制。利用該系統(tǒng)進行了遙控插秧機自動轉(zhuǎn)向性能測試試驗,，通過檢測系統(tǒng)獲得的試驗數(shù)據(jù)以系統(tǒng)識別的方法獲得執(zhí)行系統(tǒng)的傳遞函數(shù),，并分析了系統(tǒng)性能，分析表明該自動轉(zhuǎn)向系統(tǒng)可實現(xiàn)插秧機整機遙控操作,。同時分別進行了180°和90°平地轉(zhuǎn)向試驗,，試驗表明自動轉(zhuǎn)向系統(tǒng)可以實現(xiàn)預定田間工作軌跡轉(zhuǎn)向操作過程。

    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.
