    摘要:

    設計了基于藍牙技術的變量施肥機速度信號采集系統(tǒng)。該系統(tǒng)以光電編碼器為測速傳感器，ARM微處理器接收測速脈沖并計算出速度值，通過KC111適配器以藍牙（無線）方式傳送，藍牙USB適配器接收速度信號后傳送給變量施肥控制器，完成施肥機速度信號采集。試驗結果表明該系統(tǒng)最大誤差為2.92%，能夠滿足變量施肥精度要求，可以應用到變量施肥機測速系統(tǒng)中。

    Abstract:

    Measuring the ground speed is important for a variable rate fertilizer machine. Since the working environment is hard, the reliability and anti-jamming capability of the ground speed collecting system is poor. A ground speed collecting system for a variable rate fertilizer machine is developed based on Bluetooth. The ground speed sensor of the system is a photoelectric encoder, which is set on one of the wheels of the machine. An ARM microprocessor is used to receive input signals from the ground speed sensor, and calculate the working speed. And then the working speed signals are transformed into the Bluetooth signal format, and transmitted to variable rate fertilizer controller by the KC111 adapters. The maximum error of the test is 2.92%. It shows that the developed system is practical. 
