WANG Di, CHEN Guang-wu. Design of novel real-time PM2.5 concentration monitoring system for modern trolley bus[J]. 2017, 36(4): 87-89+93. DOI: 10.13873/J.1000-9787(2017)04-0087-03.
A novel GPRS-based modern 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 SIM900 A. The system are used in combination with car air purifier
