机滚船遥控驾驶系统设计

为降低劳动强度，实现水田耕作无人驾驶，以南方使用较广的机滚船为研究对象，在不改变现有结构的基础上，设计了一种遥控驾驶系统。该系统主要由电控气动执行元件、信息处理单元、信号采集系统、比例遥控收发电路等组成，可实现对机滚船的离合、换挡、转向、耕深等精确控制。试验表明，该控制系统遥控距离大于70 m，转向半径小于2.3 m，直线行驶横向偏差小于25 cm，工作可靠，环境适应性强，具有很好的应用前景。

Design of the remote control driving system for rolling boat

In order to reduce labor intensity, make rolling boat unpiloted, a remote driving control system without changing the original?structure of the rolling boat has been designed. This system is composed of electrically controlled pneumatic manipulators, information processing unit, information collection unit, proportional remote receiver and transmitter, etc. It can control the shift, the clutch, the steering and the plough of the rolling boat accurately. The experimental results show that the control distance was as far as 70 meters, the steering radius was less than 2.3 meters, the lateral deviation on a straight line was less than 25 cm, and it could adapt to the severe external environment admirably. Therefore, there is a good prospect for application of this remote driving control system for rolling boat.
