【摘要】 由于无线传输式遥测地震仪比有线传输式地震仪更能适应未来地震勘探发展的需要 ,因此 ,无线传输是今后遥测地震仪发展的趋势。 2 4位的 OPSEIS鹰系统和 I/ O系统 两种新型无线遥测地震仪的特点集中反映出目前无线遥测地震仪的新进展。新型无线遥测地震仪采用数字式频率合成器和变容二极管直接调频方式 ,实现了从中央主机对通信频率的数字控制 ,能够灵活选定干扰背景最小的频率进行指令和数据的无线传输 ,大大提高数字传输的可靠性更多还原

【Abstract】 The radio telemetry system is more suitable for future seismic exploration than the cable system.hence,the radio transmission technique is the trend of development of telemetric seismic instrument in future.The features of Opseis Eagle System with 24 bit A/D and I/O System Two Radio System reflect the new recent advances of radio telemetry system.By using digital frequency synthesizer and direct FM of varator,the new type of telemetry instrument can implement digital control of communication frequency from central unit and flexibly select the most quiet frequency for radio transferring of commands and data,which effectly improve the reliability of digital transmission.更多还原
