一种舞台吊杆控制电路设计

A Kind of Electric Circuit Design about Stage Suspender Control

舞台吊杆数量较多,每台吊杆需电机正、反转控制信号线2根;上、下限位检测线2根。本文通过优化电路设计,将4根连线减少到1根而不影响功能。

The stage has a large number of suspenders. Each suspender motor requires four signal lines： positive control signal, inversion control signal, up limit control signal and low limit control signal. Through the optimization of circuit design, four connections reduced to one without affecting the fimction.
