从三峡无线数字遥测地震台网勘选成功看无线遥测地震台网的信道
|
摘要
数字遥测地震台网采用无线信道在国内地震界借鉴的经验还非常有限。究竟数字无线遥测，能否在（１０－６）误码率指标下，象模拟无线遥测地震台网一样采用单向传输，尚有不同看法。从三峡无线数字遥测地震台网的成功勘选得到了许多有益的结果，我们关于无线信道和信道设备的探索回答了这个问题。结论是：数字地震台网仍然可以采用无线遥测方式组网，采用单向传输的信道设备既符合经济原则，技术上也是可行的。
The availble experiences in establishment of radio digital seismic networks have been quite limited in our country.There have been arguments about the single direction transmission of digital signal with code error less than 10 -6 ,but a lot of useful results were obtained in determining the Three Gorge Network,and they suggest the telemetric network can be composed in the way of radio telemetry and the single direction transmission is acceptable.
