| Abstract: | In this paper,we introduce the data transmission modes in the digital seismic telemetric network of Guangdong province and analyze the quality of the seismic waveform data transmitted by IP/VPN in quasi-real time.It is concluded that the IP/VPN transmission mode has the following characteristics: nonexistence of missing code,download and upload resume,economy,safety,etc.The application of IP/VPN not only improves the waveform data transmission quality and makes the working rate meet the requirement of the criterion,but also increases the earthquake monitoring ability and extends the monitoring scale.This technique plays an important roll in enhancing the local quakeproof work and brings evident social and economic benefit. |
