PLC中断功能在电梯给定速度曲线控制中的应用

The Application of PLC Interrupt Function to Given Velocity Curve about Elevator

利用PLC中断功能控制电梯给定速度曲线，从而有效地克服了扫描运行机制对PLC实时性的限制，实现了由PLC完成的电梯给定速度曲线的数字化产生方法。

The interrupt function was applied to improve the real-time response of PLC based on scanning mechanism and build anel-evator given veloctity curve.
