摘　　要：为进一步提高山地果园中果品农资运输的安全性和可靠性,解决传统索道张紧调节依赖于人力或机械的方法受到使用强度限制,无法对索道运行过程中驱动链张紧进行实时检测,导致张紧调节具有滞后性、自适应不强等问题,该文设计了一种山地果园索道张紧调节自动控制装置,张紧调节采用PID控制算法,可适用于不同负载条件下,实时检测驱动链张紧力变化调整索道驱动链张紧程度。试验结果表明:索道运行过程中,张紧控制系统工作在无控制和PID控制条件下,驱动链分别承受的张紧力均值变化范围为:653.5944～763.4059N和508.1988～568.7609N,能有效地实现驱动链张紧自动调节,控制系统最大跟踪误差为104N,平均误差为13.6417N。According to the problems that traditional manual or mechanical ropeway tension adjustment approaches were subjected to intensity limits and failed to detect real-time dynamic variations for driving-chain tensions,which causing corresponding hysteretic nature and poor self-adaption,a related device was designed to automatically adjust driving-chain tension by corresponding variation detection and PID control under different payloads for improving transportation security and reliability of fruits and agricultural products in mountain orchard.As a result,the detected mean values of driving-chain tension were ranging from 653.5944 N to 763.4059 N when ropeway system was running under no control,and ranging from 508.1988 N to 568.7609 N under PID control.In conclusion,this system could effectively achieve automatic driving-chain adjustment with maximum tracking error of 104 N and mean error of 13.6417 N.
