基于单片机的电动车防盗系统设计 学院名称： 电气信息工程学院 专 业： 电子信息工程 班 级： 13 电子 2B 学 号： 2025311510 姓 名： 许涛 指导老师姓名： 戴霞娟 指导老师职称： 讲师 二〇一五 年 六 月基于单片机的电动车防盗系统设计摘 要：电动车被盗的现象越来越严重，为了更好地解决这个问题，特设计一个基于单片机的电动车防盗系统。该系统由遥控部分和主控部分组成。遥控部分可以控制系统的布防、撤防和紧急报警三种状态。主控部分的防盗功能主要是通过振动传感器 SW-18010P 检测外界振动信号，然后把检测到的振动信号经过 LM393 比较器转换为电平信号送给单片机 STC89C51，一旦被推断为异常信号，单片机就驱动声光报警并且通过本 科 毕 业 设 计 （ 论 文 ）GSM 模块给车主发送短信提示，让车主及时收到报警信息并做出相应举措。本课题设计的电动车防盗系统与普通的防盗系统的区别在于，它能够在声光报警的同时，利用 GSM 无线通信技术发送短信至车主手机，对防盗报警系统进行了优化设计。关键词：电动车；GSM；防盗系统；传感器；报警信息Design of E-bikes Anti-theft System Based on MCUAbstract：The phenomena of e-bikes stolen become more and more serious. In order to solve this problem, we design a e-bikes anti-theft system based on single chip microcomputer. The system is composed of remote control part and main control part. Part of remote control can control the system within three states: protection, removal and emergency alarm. The anti-theft function of main control part mainly detects the external vibration signal via vibration sensor SW-18010P, then sending detected vibration signal which is switched to be a level signal via LM393 comparator to STC89C51. Once it is judged to be an abnormal signal, MCU will drive sound and light alarm and send message prompt to driver via GSM module, making drivers receive alarm message in time and take some corresponding measures. This design of e-bikes anti-theft system is different from normal anti-theft...
