本课题采用STC89C51单片机作为主控制器，利用遥控开关来启动和关闭防盗报警系统，采用ND-1型全向震动传感器作为检测元件，当ND-1震动传感器检测到较大振动信号时，能够从第三脚输出直流电压信号，经过放大接入单片机I/O端口。单片机检测到ND-1有信号输出时，立即通过I/O口发出相应的信号驱动扬声器发出报警信号，同时将摩托车引擎锁住，到防盗报警的目的。-STC89C51 single-chip microcomputer used in this subject as the main controller, use the remote control switch to start and shut down anti-theft alarm system, the ND-1-type omni-directional shock sensor as a detection device, when the ND-1 vibration sensor detects vibration signal larger when feet from the third DC voltage output signal, after amplification access single-chip I/O port. Singlechip detected ND-1 signal output through the I/O port to issue the corresponding signal driver loudspeakers warning signal, motorcycle engine will be locked at the same time, the purpose of the anti-theft alarm.
