校车滞留儿童检测系统的研究

随着越来越多的儿童选择坐校车,儿童因滞留在校车内出现意外时有发生。为防止儿童滞留在校车内,设计了一种校车滞留儿童检测系统。系统采用STM32单片机作为控制模块,在校车的车门处安装了两组红外对管和一个数码管作为计数模块,在车内安装了人体热释电传感器和面式压力检测传感器作为检测模块,并以SIM900A为主要装置的报警模块。此系统在启动和停驻时都具有检测装置。通过实物模拟,此系统达到了要求。

Research on Detecting System for Children Forgotten in School Buses

As more and more children choose to take the school buses,incidents of children forgotten in the school buses often occur.In order to prevent children from being forgotten in the school buses,a detection system is designed.This system uses STM32 single-chip microcomputer as the control module,two sets of infrared pair tubes and one digital tube as a counting module installed at the door of the school bus,human pyroelectric sensors and surface pressure sensors as a detection module installed in the bus,and a SIM900A as the core of alarm module.This system has detection devices at startup and parking.The physical simulation show that this system meets the requirements.
