摘要
文中设计了一种基于压电传感器的人员分布计数装置。该装置以人体坐在座位上产生的压力作为检测信号,单片机接收各区域压电传感器输入的高低电平信号并存储,判断会场的人数。还可以对人员的分布情况实现可视化分析。当有人坐在座位上时,压电传感器会产生压电信号,经过放大和检测后,输入到单片机进行处理,最后在液晶显示屏上显示人员人数和分布情况。本设计基于Proteus软件根据电路设计,搭建电路平台最后实现系统仿真。
This paper designed a kind of piezoelectric sensor based on the personnel distribution of counting device. The pressure to the device in the body seat as a detection signal, piezoelectric sensors in each region of MCU receives the input of the high and low level signal and stored, judge the number of the venue. Can also to personnel distribution of visualization analysis. When someone sitting in the seat, piezoelectric sensor will produce piezoelectric signal, after amplification and detection, the input to the single chip microcomputer, finally displayed on the LCD screen number of personnel and distribution. This design based on Proteus software according to the circuit design, establish the platform circuit finally realize system simulation.
