高速插秧机无线遥控驾驶系统的设计

针对2ZG630A型插秧机设计了一套基于STC单片机和NRF24L01无线数传模块的遥控驾驶系统。遥控驾驶系统采用带位置传感器的电动推杆来控制速度的大小与方向,通过步进电机带动方向盘达到控制插秧机转向的目的,并设计了控制发动机的点火/熄火电路。系统下位机软件采用模糊控制算法实现了对插秧机转向和速度的精确控制,利用基于VB.NET2008编写的上位机软件,通过2.4G无线模块来与下位机进行通讯,达到遥控插秧机的目的。经试验,在100 m遥控距离内,系统运行可靠,响应速度快,控制平滑灵敏。

Research on driving system with wireless remote control in high speed rice transplanter

A remote controlled driving system based on STC MCU and NRF24L01 wireless-data-transmitting module has been designed for 2ZG630A transplanter.The remote controlling system uses electric motivated handspike with the position sensor to control the speed and the direction through the steering wheel driven by stepping motor,and ignition/flameout circuit was designed to control the ignition/flameout of the engine.Through the fuzzy controlling algorithm adopted in the software of slave computer,the direction and speed was controlled precisely.With the communication between the software of host computer written by VB.NET2008 and slave computer through wireless module of 2.4G,the remote control of the rice transplanter was realized.From the test,we can get the conclusion that the system is reliable,the response velocity is fast and the control device is sensitive within a distance of 100 m.
