基于动态无线充电的草莓温室大棚自动输送车系统设计

Design of Automatic Vehicle System for Greenhouse Strawberry Based on the Dynamic Wireless Charging

鉴于草莓在温室大棚内运输时易受损伤,提出一种动态无线充电的草莓温室自动输送车系统。设计了以MSP430F5529LP单片机为主控核心的软硬件控制电路,采用3个灰度传感器循迹黑线轨道,保证输送车稳定运行;通过整流模块、稳压模块和继电器模块为超级电容模块充电,提高了充电效率,并使用TB6612FNG模块对电机转速进行控制;输送车具有自启动功能,达到预设充电时间后可自动沿轨道行走。试验结果表明,系统运行状态良好,能够有效实现输送车的循迹、动态无线充电与自启动,可降低劳动强度,减少人工成本,实用前景良好。

For investigating the strawberries are vulnerable to be damaged when transported in the greenhouse;an automatic vehicle system of greenhouse strawberries based on the dynamic wireless charging is developed in this paper.The MSP430F5529LP microcontroller is used as the controlling core of the control circuit.The system utilizes three gray scale sensors to track the black orbit,which maintains the stable operation of the transport vehicle.The charging efficiency is improved by rectifier module,voltage regulator module and relay module charging to super-capacitor module.And the TB6612FNG module is used to control the motor speed.The transport vehicle has a self-starting function to automatically walk along the path after reaching the preset charging time.Experiments have shown that the system is running well,which can realize track of the transport vehicle effectively,and charge wirelessly and start automatically.The dynamic wireless charging technology is applied to the transport of greenhouse strawberries,which can relieve labor force and reduce labor costs,the application trend is favorable.
