浅析无仪器主机如何实现可控震源Smart LF技术

An analysis of how instrument-free hosts can realize Smart LF technology for vibroseis

Sercel公司推出可控震源低频去谐波功能简称Smart LF,该功能能够显著降低可控震源在低频段的畸变,需要匹配508XT仪器主机激活才能使用,适用于VE464电控箱体的4.0及以上版本。可是随着节点设备的推广应用,不再需要仪器主机就可以独立作业,在没有508XT仪器主机的情况下该如何实现Smart LF功能,SMA软件完美移植了508XT仪器主机管理可控震源的功能,能够在无仪器主机情况下激活Smart LF,从而实现Smart LF的独立操作和使用。

The Sercel company has developed a function called Smart LF,which aims to reduce harmonic wave,can significantly reduce the distortion of all vibroseis in the low frequency band.Initially,this function required the use of the 508 XT instrument host and was compatible with the VE464 decoder version 4.0 and above.How-ever,with the advancement of node instruments,the need for the instrument host has been eliminated,allowing independent operation.To achieve the Smart LF function without the 508 XT instrument host,the SMA software has been developed.This software perfectly inherits the capabilities of management vibroseis of the 508 XT instrument host.As a result,it can activate the Smart LF function even in the absence of the instrument host,enabling independent operation and utilization of the Smart LF.
