摘要
由于汽车安全的报警措施相对单薄,所以开发了车载报警设备,将监控设备放于车内,一旦有人破窗或破门即可电话报警。整个系统采用AT89S52单片机作为控制器,SIM300作为无线通信模块,热释电红外传感器HRS501作为检测单元,如果检测单元检测到有人破窗进入车内,红外探测器就会发出一个脉冲跳变,AT89S52单片机能够控制SIM300模块发送短消息或直接拨打电话给用户的手机实现报警,使报警系统更加及时有效。
Due to the automobile safety alarm measures is relatively weak, so tbe use of AT89S52 as the con- troller, SIM300 as the wireless communication module, pyroelectric infrared sensor HRS501 as the detection unit, if the unit detects that someone has broken into the car window, the infrared detector will emit a pulse jump, AT89S52 microcontroller to control the SIM300 send module short message or call directly to the user＇s mobile phone alarm, the alarm system more effective.
