摘要:

针对近年来车辆驻停后滞留车内人员受高温致死和车内气体污染等伤害的安全问题,设计了一种基于MIMO(Multiple-Input Multiple-Output)雷达及高精度北斗定位的车内人员防遗监测系统。该系统使用MIMO雷达作为人体探测的手段,采用高精度北斗定位的车辆运动检测方法,融合现有成熟的温度、气体传感器技术、4G通信技术,并使用基于Matlab APP Designer的上位机软件作为硬件配置及测试软件；系统的车载终端硬件系统具有独立、小型化的特点,能在车内多个地方布置,在上位机平台可观察各传感器的数据变化。系统实现了车辆运动检测、车内人体探测、车内环境监测、数据无线上传等功能,验证了系统在车内监测的可行性,为车载生命监测提供了一种独立、便捷、高效的新方法。

Abstract:

Aiming at the safety problems such as the death caused by high temperature and the injury caused by gas pollution inside the vehicle in recent years, an anti-legacy monitoring system for in-vehicle personnel based on Multiple Input Multiple Output (MIMO) radar and high-precision Beidou positioning is designed. The system uses MIMO radar as a way to detect human body, adopts high-precision beidou positioning vehicle motion detection method, and integrates existing mature temperature, gas sensor technology and 4G communication technology,and uses the software based on Matlab APP Designer as a configuration and test software. The hardwore terminal of the system is independent and miniaturized, which can be arranged in multiple places in the car, and the data changes of each sensor can be observed on the software. The system realizes the functions of vehicle motion detection, human body detection, environment monitoring and data wireless uploading in the car.The system verifies the feasibility of the system monitoring inside a car, which can also provid an independent, convenient and efficient new method for interior life monitoring.
