Mobile Monitoring System for Gas Sampling Based on Zigbee, 4G and Web GIS

For the realization of the real-time collection, upload, visualization and intelligent management of air quality data, mobile management system of gas sampling was designed based on the technologies including Web GIS, ZigBee wireless sensor network, the 4G (4th generation) communication system and so on. The ZigBee module is mainly used for wireless communication between PDA and mobile sensor nodes. The 4G module is used to upload data uploaded by ZigBee terminal nodes to the remote server through TCP/IP protocol, to realize remote monitoring of spatio-temporal variation of gas information. The real-time tracking of gas sampling can be realized through Digital Map, with the combination of GPS information and Web GIS technique. The spatial distribution figure of gas sampling can be generated automatically by calling data stored in database. It can guide the the follow-up of manual decision effectively.
