智能校车安全预警装置设计

Design of Intelligent School Bus Safety Warning Device

为防止儿童被遗忘在车内导致的安全隐患,设计了一款基于STC89C51单片机的智能校车安全预警装置,集成被动红外探测器、温度传感器及一氧化碳传感器,分别监测车内遗留儿童、温度及有害气体浓度。一旦发现异常,如儿童遗留、温度过高或有害气体超标,装置即启动车内报警器与语音提示,并通过GSM模块向预设紧急联系人发送报警信息及拨打电话,迅速响应以确保儿童安全。系统由传感器采集模块、控制电路、语音模块及GSM通信模块构成,有效防止儿童被遗忘车内,保障其生命安全。

To prevent safety hazards caused by children being forgotten in the car,an intelligent school bus safety warning device based on STC89C51 microcontroller has been designed.It integrates passive infrared detectors,temperature sensors,and carbon monoxide sensors to monitor the presence of children,temperature,and harmful gas concentration in the car.Once an abnormalities is detected,such as children leaving behind,high temperatures,or excessive harmful gases,the device will activate the car alarm and voice prompts,and send an alarm information and make a phone call to the preset emergency contact through the GSM module to quickly respond and ensure the safety of the child.The system consists of a sensor acquisition module,control circuit,voice module,and GSM communication module,which can effectively prevent children from being forgotten in the car and ensuring their life safety.
