【摘要】 本文对当前地震数据采集记录系统(地震仪器)的结构与使用状况进行了分类和分析．介绍了408UL、IM-AGE、ARIES、BOX、IT 等目前最常用的几种大型有线或无线地震仪器；介绍了目前地震仪器采用的Σ——Δ型的 ADC技术、网络遥测技术、多进制数字调制技术、蜂窝技术以及 GPS 时钟同步技术等多种新技术．从目前地震勘探所面临的环境及保护、勘探成本、勘探效益、勘探精度等问题出发，阐述了仪器所面临的道数和传感器等问题，认为地震仪器应该向传感、定位、采集、传输一体化的高度智能自由组合系统发展．更多还原

【Abstract】 The structures of current seismic data acquisition system(seismic instruments)are assorted and the statusof their application is analyzed in this paper.The several most advanced wire or wireless instruments used currentlysuch as 408UL,IMAGE,ARIES,BOX,IT etc.are briefly introduced.Some new techniques such as Delta-Sigmaanalog-to-digital conversion(Σ—△ type of ADC),seismic areal networks and multi-path telemetry,multi-level digitalmodulation,cell and GPS clock synchronization etc.are mainly discussed.Relative to the problems of environmentprotection,the cost,benefit and precision of exploration faced by seismic exploration,channels and geophones of theinstruments are described.It is pointed out that the seismic instruments should be developed to a free combinationsystem with high brainy integration of sensing,locating,collecting and transmitting.更多还原
