防止儿童误锁车内报警系统的设计
|
摘要
为了避免儿童被误锁车内,设计了一种基于单片机的车内监控报警系统。系统主要包括信号采集、信号处理和驱动执行三部分。单片机通过传感器检测车锁及车内状况,当危险存在时,进行声光报警和车窗升降,同时通过GSM模块向车主发送信息,提醒驾驶员及时返回处理。理论分析和实验测试表明,该系统能够有效减少儿童被误锁车内事件的发生。
In order to avoid children being accidentally locked in the car,a kind of monitoring alarm system based on MCU is designed. The system mainly includes three parts of signal acquisition,signal processing and driver implementation. The car lock and condition are detected by sensors. When there is a danger,the sound and light alarm issue a warning,and the window goes down. At the same time,the GSM module sends information to the owner,and reminds the driver to return in time. Theoretical analysis and experimental tests show that the system can effectively reduce the occurrence of children accidentally locked in the car.
