摘要:: 目前的防盗系统主要通过判断行李与用户之间的距离,来确定行李箱是否安全,缺少行李运动状态,造成判断精度较差,适用范围较小。针对以上问题,设计了一种基于 Arduino 的智能防盗系统。 Arduino 通过各种各样的传感器来感知环境,与各种硬件搭配可以实现对系统的智能控制。通过 Arduino101 板载惯性测量单元以及超声波传感器来收集行李箱的运动姿态数据,使用 Madgwick 滤波算法和 AHRS 姿态算法对感知数据进行处理,得到行李箱的实时运动姿态。根据姿态分析和超声波测距联合判断行李箱是否丢失,并提醒用户。该系统解决了原方案不能准确判断行李箱运动状态的问题,实现了行李箱精确检测、智能防盗,即当行李箱非正常移动时可及时触发蜂鸣器并发出警报声,通过短信模块发送报警短信到用户手机,有效规避财务损失。

Abstract:: At present,the anti-theft system mainly determines whether the luggage is safe by judging the distance between the luggage and the user. Due to the lack of luggage movement status,the judgment accuracy is poor and the application scope is small. To solve the above problems,an intelligent anti-theft system based on Arduino is proposed. Arduino senses the environment through various sensors and can realize intelligent control of the system with hardware. It uses Arduino101 onboard inertial measurement unit and ultrasonic sensors to collect movement posture,and employs Madgwick filtering algorithm and the AHRS algorithm to process the data obtained to get the real-time motion posture of the case. The attitude analysis and ultrasonic ranging jointly judge whether the luggage is lost and remind the user. The system solves the problem that the original plan cannot accurately judge the movement state of the luggage,and realizes the accurate detection and intelligent security of the luggage. That is, when the suitcase moves abnormally, it can trigger the buzzer and give out the alarm sound in time,and send alarm messages to the user’s mobile phone through the SMS module to effectively avoid financial losses.
