摘　　要：设计了负荷传感系统,使液压泵的输出压力与负载需求相匹配,以降低液压电梯的能耗,并改善乘坐电梯的舒适性。设计了以TL494为核心的控制电路,对负荷传感系统进行了液压电梯台架试验,结果表明初步达到了设计要求。For reducing energy consumption and improving comfortability of hydraulic lift, load - sensing sys-tem is designed. The system enables difference of output pressure of pump and load pressure to be fixed. Its electric circuit is also designed, whose key part is TL494. By the results of experiment, the system has the capacity of sav-ing energy and improving comfortability.
