基于多传感器的地铁站台上车点择优技术

The Technology of Selecting the Best Boarding Points on Subway Platforms with Multi-Sensors

为缓解地铁高峰期出行人流量大,容易在楼梯两侧拥堵,造成候车乘客分布与各车厢拥挤程度不匹配,进而使得乘客在车厢分布不均的情况,设计了上车点择优系统。该系统利用2对红外传感器和2对超声传感器来监控每次上下车厢的人流量,通过STM32F103单片机处理,统计出各节车厢内人数,然后将数据传输至候车区的USART HMI串口显示屏上,使候车乘客了解各节车厢内的拥挤情况,从而选择更优的上车点。上述系统可以改善人们在采用轨道交通出行时,候车位置选择的盲目性和随机性,避免候车客流分布差别很大的情况出现。

The fact that during the rush hours people usually get on the subway trains from the boarding points near the stairs and escalators often results in uneven distribution of passengers to each subway carriage.In response to this issue,a carriage selecting system is designed to monitor passenger flow in and out of the carriage each time with two pairs of infrared sensors and two pairs of ultrasonic sensors.STM32 F103 single-chip processing system counts the number of people in each carriage and send the data to the USART HMI serial display screen at the boarding points for the waiting passengers to choose less crowded carriages.This system can avoid passengers’randomicity when choosing boarding points of railway vehicles and alleviate imbalanced passenger distribution among carriages.
