21世纪是一个信息社会,人们的生活节奏越来越快,同时随着科学技术的不断发展,他们设计出各种不同的电子自动化仪器来代替复杂低效率的重复劳动.对十字路口每天通过行人数的统计、在高速公路的某一路段统计每天车流量和图书馆等流动人口密集的地方统计一天各个时刻通过该区域的人数等方面,可以通过设计制作流动人口计数器来达到自动统计的目的.流动人口计数器主要是通过传感器自动识别人的进出,自动统计脉冲个数并进行加减可逆计数,从而显示进出人数和现有人数等,特别适用于一些公共场合的管理和统筹.我们采用的的是红外光电传感器检测电路,其电路可分为三个部分,分别为红外发光、受光电路,信号接受电路,计数电路和译码驱动显示.

BE an information societies for 21 centuries,people's living rhythm is more and more quick,is technical along with science in the meantime of develop continuously,they design a various different electronics automation instrument to replace the repeated labor of[with] complicated and low efficiency.Pass the covariance of the pedestrian number everyday to the intersections,in the superhighway of some all the way segment covariance everyday fluid populations such as the car discharge and library etc.the intensive place statistics for a day,each pass the number of that districts every moment etc.aspect,can count a machine through the design manufacture fluid population to attain automatic covariance of purpose.The fluid population counts a machine mainly is pass to spread the feeling machine to identify a person to pass in and out automatically,statisticsing the pulse piece to be also carry on add and subtract automatically can go against to count,thus showing to pass in and out the number and existing number etc.,being applicable to the management and the orchestration of some public situations specially.We adopt of of is the red and outside light fax feeling machine examination electric circuit,its electric circuit can is divided into three parts,the difference gives out light,be subjected to the light electric circuit for the red outside,the signal accepts electric circuit,counting electric circuit and translating code to drive a manifestation.
