自动扶梯作为一种方便快捷的运输工具,已经越来越多地出现在众多的公共建筑中,尤其在宾馆、商厦及地铁车站的建设中,扶梯的使用呈现明显上升的趋势。但由于其使用场合的特殊性,部分扶梯经常处于轻载或空载的状态,这必将浪费大量的电能,同时也会造成扶梯的磨损。本文对自动手扶电梯的运行与节能方案进行探讨,在已经采用高灵敏的远红外传感器、PLC控制变频器等高科技配合智能电路实现无人自动减速有人自动加速的前提下,运用电路将电梯自身的动能和势能在释放时收集起来,有效地转换为电能,并回送给交流电网,同时利用数理方法确定出更科学的电梯变速时间间隔,从两方面精确地的讨论,其他方面辅助达到节能的目的。
As a convenient and fast means of transport, escalators have been appearing more and more in many public buildings. Especially in the construction of hotels, commercial buildings and metro stations, the use of escalators has shown a clear upward trend. However, due to the particularity of its use occasions, some escalators are often under light load or no load conditions, which is bound to waste a lot of power and cause the escalator to wear out. This article discusses the operation and energy-saving solutions of automatic escalators. Under the precondition that high-sensitive far-infrared sensors, PLC-controlled frequency converters and other high-tech intelligent circuits are used to realize unmanned automatic deceleration and some people are automatically accelerated, the circuit is used to lift the elevator Its kinetic energy and potential energy are collected at the time of release, effectively converted into electric energy, and sent back to the AC grid. At the same time, mathematical science methods are used to determine a more scientific elevator transmission time interval. Precise discussions are made from two aspects. Other aspects help to save energy the goal of.
