The invention relates to a movable flickering reminding device for passengers approaching an escalator exit. The movable flickering reminding device is characterized by comprising a 12V direct-currentpower supply, a voltage comparison and level feedback type low-frequency oscillating circuit and a white and orange, yellow and red light-emitting tube driving circuit, wherein the model of an operational amplifier IC1 in the level feedback type low-frequency oscillating circuit is CA3130. The escalator has the advantage of continuously and quickly evacuating a large amount of people, thereby being suitable for places such as supermarkets and subway stations. Due to the fact that the passenger flow density is large, the advancing position of the escalator cannot be seen clearly, or young people who lower the head to watch the mobile phone do not pay attention to escalator operation, the escalator operates to reach an exit, passengers do not get ready in advance, crowd congestion is proneto happening, collective falling is caused, or various injuries are caused by improper foot falling positions and stumbling. In order to relieve the accidents, passengers watching mobile phones in a countersunk mode do not need to stare at the escalator to operate all the time, the accidents are effectively avoided, and the safety and comfort of taking the escalator are greatly improved.
本发明是关于一种乘客抵近扶梯出口移动式闪烁提醒装置,其特征包括12V直流电源、电压比较及电平反馈式低频振荡电路、白色和橙色、黄色和红色发光管驱动电路,所述的电平反馈式低频振荡电路中运算放大器IC1选用型号为CA3130。自动扶梯具有连续快速疏散大量人流的优越性,因而适用于大型商场、地铁站等场所。搭乘人流密度大因看不清扶梯的行进位置、或因低头观看手机的年轻人不太注意扶梯运行,扶梯运行快要到达出口而乘客未提前做好预备,容易发生人流拥堵而集体摔倒或落脚位置失当、绊倒而导致各种伤害。为缓解这类事故,使用本发明对埋头观看手机的乘客不用眼睛时刻盯着扶梯运行,有效避免此类事故的发生,大大提高了乘梯的安全性和舒适性。
