摘要:

本文阐述了工程勘查钻进数据采集设备的研制背景和性能要求。重点介绍了工程勘查钻进数据采集设备的主要结构和性能参数，工程勘查钻进数据采集设备的电气控制系统及重要电器元件选型。详细阐述了钻头输出恒定转速的自动闭环控制方案。最后经过施工现场试验，验证了工程勘查钻进数据采集设备能够输出恒定钻速，精确采集并存储钻头转速、扭矩、钻进速度、钻进压力等4个主要钻进参数。

Abstract:

This paper describes the development background and performance requirements for geotechnical drilling data acquisition equipment. The main structure and performance parameters of geotechnical drilling data acquisition equipment are introduced together with the selection of the electrical control system and the important electrical components. The automatic closed-loop control scheme for constant rpm output at the drill bit is described in detail. Field test has verified that the geotechnical drilling data acquisition equipment can output a constant drilling rate, and accurately collect and store four main drilling parameters.
