通过对旋挖钻机电气控制系统常用元件进行细致的研究,在此基础上又对旋挖钻机电气控制系统的工作原理进行分析,从而对旋挖钻机电气控制系统进行设计。在设计中分为系统硬件设计、系统软件设计两个部分,从而实现了利用电脑控制系统及电子组件进行旋挖钻机安全施工的目的,为今后的旋挖钻机电气控制系统的研究提供参考。 Through the careful research on the commonly used components of rotary drilling rig electrical control system, on the basis of this, the working principle of rotary drilling rig electrical control system is analyzed, and the electrical control system of rotary drilling rig is designed. In the design, it is divided into two parts, system hardware design and system software design, so as to realize the purpose of safety construction of rotary drilling rig by using computer control system and electronic components, and provide reference for future research on electrical control system of rotary drilling rig.
