Design and implementation of on-line automatic monitoring system for malodor pollution incidents based on ArcGIS

Online automatic monitoring system of malodor pollution, which can realize real-time, automatic monitoring, risk assessment and emergency treatment, was designed to improve the handling ability of malodor emergency. In this paper, remote sensing monitoring odorous pollutants diffusion, assessment and per-warning for emergency were studied through the combination of the ArcGIS database with real-time monitoring data of malodor, meteorological parameters and so on. Malodor pollution monitoring equipment integrated dual detection technology was developed and real-time monitoring data communication was standardized referring to national standard. Center data center of the monitoring system was structured on Hadoop cloud computing platform. Relying on the environmental protection supervision, cooperative supervision is achieved, which was supported by Internet of things for City-Province-Country monitoring network. As the national key scientific instruments to develop dedicated in 2012, through applied in Dagang Industrial Park of Tianjin Binhai New Area, the system is proved that it directly enriches the environmental internet of things, fundamentally enhances the malodor monitoring level and improves the environmental supervision capability in China.
