【目的】设计适用于山地果园牵引式双轨运输机的控制系统,为山地果园牵引式运输机械的设计提供支持。【方法】在分析该类拆装牵引式双轨运输机整机结构及应用工况的基础上,针对山地果园拆装牵引式双轨运输机拆装频繁、应用环境恶劣等工况,运用控制系统硬件、软件设计理论与性能试验相结合的方法,设计一种以PLC为控制核心、液晶触摸屏为人机交互窗口的控制系统,重点分析控制系统的工作原理、硬件设计、软件设计、无线遥控设计和抗干扰措施,并对控制系统的核心部件及稳定性进行理论和试验研究。【结果】所设计的山地果园拆装牵引式双轨运输机控制系统运行可靠,定位系统的平均距离偏差为5.18cm,平均定位距离误差率为0.96%,平均脉冲误差率为0.68%;在有遮挡的情况下,无线遥控器在距离遥控接收装置300m范围内的通信成功率为100%。【结论】所设计的控制系统可满足运输机的智能化控制需求,该控制系统亦适用于其他钢丝绳提升式运输机的作业控制。

【Objective】A traction double track transport for mountain orchards was designed to provide support for design of transport machinery in mountain orchards.【Method】Mountainous orchard detachable traction double-track transport was used in harsh environment conditions and disassembly and assembly were conducted frequently.Based on analysis of the whole structure and application conditions of detachable traction double track transport in mountain orchards,this paper designed a control system that used PLC as control core and LCD touch screen as man-machine interactive window by combining the design principal of control system hardware,software design and performance test experiments.It focused on the analysis of working principle,control system hardware design,software design,wireless remote control design,and anti-interference measures.The paper also made theoretical and experimental research on the con-trol system of core components and its stability.【Result】The designed detachable traction double-track transport control system for mountain orchards was reliable.The average distance of rotary encoder positioning system was 5.18 cm,the average positioning distance error rate was 0.96%,and the average pulse error rate was 0.68%.The wireless communication reliability of the wireless remote control was 100%when the remote control was within 300 mto the remote control receiver with obstacles.【Conclusion】This control system met the demand of intelligent control of this transport and was applicable to operation control of other wire rope lifting transport equipment.
