基于蓝牙技术的变量施肥机速度采集系统设计（Development of a Ground Speed Collecting System for the Variable Rate Fertilizer Machine Based on Bluetooth）
精确农业 变量施肥 速度采集
2009/12/28
设计了基于蓝牙技术的变量施肥机速度信号采集系统。该系统以光电编码器为测速传感器，ARM微处理器接收测速脉冲并计算出速度值，通过KC111适配器以蓝牙（无线）方式传送，蓝牙USB适配器接收速度信号后传送给变量施肥控制器，完成施肥机速度信号采集。试验结果表明该系统最大误差为2.92%，能够满足变量施肥精度要求，可以应用到变量施肥机测速系统中。
