The invention relates to an escalator (100) comprising: at least one sensor (120) associated with a drive system (610) of the escalator and configured to generate measurement data indicative of a molecular concentration in air in an operating space of the at least one sensor (120); and a control unit (130) configured to receive (510) measurement data from the at least one sensor (120). The control unit (130) is configured to generate (520) a pattern indicative of a concentration of molecules in the air, compare (530) at least a portion of the generated pattern to at least one reference pattern, and generate (540) a detection result to express one of i) normal operation of the escalator (100), ii) failure of the escalator (100). The invention also relates to a method, a control unit and a computer program product thereof.

    本发明涉及自动扶梯(100),包括:至少一个传感器(120),该传感器与自动扶梯的驱动系统(610)相关联,并配置为生成指示至少一个传感器(120)的操作空间中空气中的分子浓度的测量数据;以及控制单元(130),其配置为从所述至少一个传感器(120)接收(510)测量数据。控制单元(130)配置为:生成(520)指示空气中的分子浓度的图案,将所生成的图案的至少一部分与至少一个参考图案进行比较(530),并生成(540)检测结果以表达以下之一:i)自动扶梯(100)正常操作,ii)自动扶梯(100)故障。本发明还涉及一种方法、控制单元及其计算机程序产品。
