物联网车载多层次监测报警系统设计
Design of multi-level monitoring alarm system for vehicle-bone with internet of things technology

针对近一段时间以来弱势群体（尤指婴幼儿、残障人士）因滞留车内而引发的安全事故频发，且传统监控方法存在着监测层次单一、易对车况造成影响的问题，设计了一种以Arduino开发平台为基础的无线远程监测系统. 该系统通过Grove-Gas(O2)、DHT、热释电三种传感器监测环境信息，经微处理器分析判断，凭借OneNet平台强大的数据储存、数据分析能力，通过GPRS无线通信、http协议、终端APP开发等技术，实现对车内环境的多层次监测报警.
Due to the vulnerable groups (especially infants，people with disabilities) suffered frequent safety accidents，the traditional monitoring methods have a single monitoring level，which have an adverse effect on the car condition. To solve this problem，an wireless remote control system based on Arduino development platform is designed. The system monitors environmental information through Grove-Gas(O2) sensor、DHT sensor and pyroelectric sensor. The microprocessor will make the judgment，with the strong data storage and analysis capacity of OneNet platform，through GPRS wireless communication，HTTP protocol and terminal APP development technology，multi-level monitoring and alarm of the in-car environment can be realized
