摘要

在无线数字遥测地震台网中,信道测试是台网传输的关键环节,关系到台网的运行率和地震信号的可用率,甚至整个台网建设的成败。信道测试有3方面的内容:中继站背景场强测试、子台信道储备测试和信道误码测试。经测试后得到各种参数柱状图,以此判断每个台站的信道质量情况,及时调整台网信道传输的设计方案,确保成功建成无线数字遥测地震台网。
For the wireless digital telemetric seismic network, transmission channel testing is a key process of network transmission. It has an important bearing on the running rate of seismic network, the useful rate of seismic signal, and even the success or failure of the whole seismic network. Transmission channel testing has three contents: the background electromagnetism field testing of a relay station, the level reserve testing of transmission channel of station, the error code testing of transmission channel. We got histogram of these parameter to estimate transmission channel quality of every station, then adjust network design plan basis on transmission channel case to build wireless digital telemetric seismic network successfully.
