An audio and video network monitoring system for weather modification operation transmitting information by 3G,ADSL and Internet has been developed and applied in weather modification operation of Tai’an City.The all-in-one machine of 3G audio and video network highly integrates all front-end devices used for audio and video collection,communication,power supply and information storage,and has advantages of wireless video transmission,clear two-way voice intercom with the command center,waterproof and dustproof function,simple operation,good portability,and long working hours.Compression code of the system is transmitted by dynamic bandwidth,and compression rate varies from 32 kbps to 4 Mbps under different network conditions.This system has forwarding mode,that is,monitoring information from each front-end monitoring point is transmitted to the server of the command center by 3G /ADSL,and the server codes and decodes again,then back-end users call images from the server,which can address 3G network stoppage caused by many users calling front-end video at the same time.In addition,the system has been applied in surface weather modification operation of Tai’an City,and has made a great contribution to transmitting operation orders in real time,monitoring,standardizing and recording operating process,and improving operating safety.
