VPHD电控箱体在G3iHD系统中的应用

The application of VPHD vibroseis source controller in G3iHD system

VPHD是INOVA公司新一代可控震源电控箱体,它是G3iHD仪器实现高效采集关键的组成部分。本文对VPHD与G3iHD仪器联机方式、主机和编码器GPS授时原理、VPHD编码器与Shot ProⅡ译码器井炮模式施工的主要参数设置及其同步测试方法进行了介绍,并对VPHD可控震源模式下的传统模拟电台同步和GPS时间约定启动两种工作模式的原理、实现方法和质控方法进行了详细阐述。

INOVA’s Vib Pro HD is a new generation vibroseis source controller which is the key part of G3 i HD instrument to realize high efficiency acquisition. The text introduces the hardware connection between VPHD and G3 iHD instrument, the GPS timing method and principle of VPHD encoder and G3 iHD, the main parameter setting and synchronous test method of VPHD shooting Shot ProⅡ decoder mode in detail. And thetwo communication modes of VPHD in the traditional analog radio synchronization and the digital radio GPS time synchronization, including the work principle, implementation method and quality control method are described in detail。
