中文摘要：
设计了一种新型的基于GPRS的现代有轨电车内PM 2.5浓度实时监测系统。系统包括车载硬件终端和中心平台,车载硬件终端实现对电车内PM 2.5浓度数据采集;中心平台以TCP协议的Socket通信为基础,采用Visual Basic软件设计,能实时显示和记录车内PM 2.5浓度的动态曲线以及历史数据。车载硬件终端与中心平台间采用GPRS网络模块SIM900A通信。该系统通过与车内空气净化器组合使用,可提高车内空气质量。
英文摘要：
A novel GPRS-based modem tram car PM 2.5 concentration real time monitoring system is designed. Vehicle monitoring system includes a hardware terminal and a central platform, on board hardware terminal is used to achieve tram car PM 2.5 data collection; center platform on the basis of Socket communication of TCP protocol, using Visual Basic software design, can real-time display and record PM 2.5 dynamic curves and historical data in car. On board hardware terminal communicates with center platform using GPRS networks module SIM900A. The system are used in combination with car air purifier, that can improve air quality inside trolley bus.
