The invention discloses a subway carriage passenger carrying condition early warning and guiding system, and the system comprises: a sensor detection system. which acquires the current pedestrian volume in each carriage of a subway which is about to enter a station; a PLC control system, which is internally equipped with a preset congestion level module to accurately divide the congestion level ofthe carriage; the PLC control system outputs a control signal to control an indicator light system to give a prompt according to the current pedestrian volume obtained by the sensor detection systemand the congestion level output by the congestion level module. A human body infrared intrusion detection sensor is adopted to judge the situation that passengers enter and exit from a carriage; a proximity sensor at the exit of the subway carriage is used for completing final detection to confirm whether passengers get on the vehicle or not; the number of passengers going in and out is calculatedthrough the PLC so as to judge the number of passengers in each carriage to obtain a corresponding pedestrian volume value area; and finally, different indicator lights in front of each carriage areturned on in different personnel number intervals, so that passengers outside the vehicle are reminded to avoid people flow congestion, and the purpose of evacuating people flow is achieved.
本申请公开了地铁车厢载客情况预警与引导系统,包括:传感器检测系统,传感器检测系统获取即将进站的地铁的各车厢内的当前人流量;PLC控制系统,PLC控制系统内预设拥挤等级模块准划分该车厢的拥挤等级;PLC控制系统根据传感器检测系统获取的当前人流量根据拥挤等级模块输出的拥挤等级,输出控制信号控制指示灯系统进行提示。本申请采用的人体红外对射传感器判断乘客进出车厢情况;地铁车厢出口的接近式传感器则是完成最后的检测确认乘客是否登车;通过PLC计算乘客进出数量从而判断每节车厢内的人数得到相应人流的量值区;最终不同人员数量区间亮起每节车厢前不同的指示灯,以此提醒车外乘客避免人流拥堵而达到疏散人流的目的。
