Meteorological department's business operation and data transmission mainly rely on the meteorological information network. Due to the timeliness requirements of meteorological data transmission, the meteorological information network must maintain 24-hour uninterrupted operation. Once the network is interrupted, it will affect the meteorological operation and the timeliness and integrity of the data. If it happens in the extreme weather process, it may cause irreparable losses to the country and society. According to the actual situation of meteorological information network operation and meteorological data transmission, this paper designs and implements Nanchong meteorological information network monitoring system by using J2EE+MySQL+Android mobile phone. The system mainly includes monitoring, alarm, system web interface and other main functional modules.
