【摘要】 网络通讯是决定地震勘探仪器系统性能和规模的关键核心技术之一,按照所采用的数据传输方式,数字地震仪目前可分为有线遥测地震仪、无线遥测地震仪和无缆存储式地震仪.本文分别举例介绍了三类地震勘探仪器中应用的经典地震网络通讯技术,并对其设计理念、网络通讯原理、通信构架、通信协议进行了分析和对比,针对有线地震仪器的电缆管理难、无线地震仪器的数据传输稳定性差和无缆存储式地震仪缺少质量监控手段的问题,讨论了无线监控与本地存储相结合的地震网络通讯技术方案,提出了基于宽带无线通信技术的无缆无线混合型地震仪的设想.更多还原

【Abstract】 Network communication technology is one of the key technologies that decide seismic scale and seismic exploration system performance.At present,the digital seismometers according to the data transmission ways can be divided into three classes:the cable telemetry seismometers,wireless telemetry seismometers,cable-less seismic acquisition system.This paper gives examples about seismic network transmission technique’s application in the introduced three types of seismic exploration classical instruments,their design ideas,network transmission principle,communication structure,communication protocol are analyzed and compared.for cables management difficulty of the cable seismic instrument,poor stability of the wireless data transmission and lack of monitoring method of cable-less seismic acquisition system,we discuss the seismic network transmission technology solution based on wireless monitoring and the local store and put forward the wireless and cable-free mixed seismometer assumption based on the broadband wireless communications technology.更多还原
