IMAGE仪器的野外联机生产

In-line production of Image seismograph in field.

目前IMAGE仪器单台带载能力是 1ms。 30 0 0道、通过主、从方式将它连接起来 ,使其能够达到 1ms ,6 0 0 0道的带载能力 ,来满足野外大道数采集的要求。本文主要说明两台仪器联机时 ,硬件的连接方法 ,讲述了两台仪器连机的工作原理和工作时序关系 ,且通过室内和野外的试验分析 ,论述了联接的可靠性 ,并且在文中给出了该仪器在野外生产时发生的问题和排列方法 ,使该技术能够在野外生产中得到更广泛的应用。

The current capacity of single IMAGE seismograph is 1 ms and 3000 channels. Using master-slave mode to connect them so that they can reach the capacity of 1 ms/6000 channels, met the needs of field acquisition with more channels. The paper mainly described the connecting method of hardware, working principle and working time-order relation for in-line two seismographs; the paper also illustrated the reliability of connection by experimental in-door and field analyses and gave easily-produced faults and spread patterns when using the seismographs for field operation, which made the technique be more widely used in field production.
