【摘要】 为了对楼宇内人流量进行监测,设计了基于嵌入式系统、光电检测技术、超声测距技术相结合的新型人流量监测系统。系统采用多传感器数据处理方式,由两对对射式红外传感器、两对反射式超声传感器组成。对射式红外传感器、反射式超声传感器同时工作,由对射式红外传感器判断人员的进出方向,反射式超声传感器判断人员通过时每排的人数,每个传感器采集后得到的数据通过串口输出方式传送至嵌入式微处理器即系统主控制器,主控制器进行数据处理并显示其结果。通过测试,系统较精确地实现了人流量的检测,特别是针对2人并排进出情况下的监测可以得到准确数据,具有实用性和广泛性。更多还原

【Abstract】 With the progress of human society,population density is on the increase,and the safety in buildings has drawn great attention.It is of significance to develop a disaster rescue system for any unexpected incident.In order to monitoring the visitors’ flow rate in buildings,a novel system based on embedded system,photoelectric detection technology and ultrasonic ranging technology was designed by using data processing system of multi-sensor.The test result shows that the system can precisely monitor visitors’ flow rate and can be applied universally.更多还原
