旋挖钻机的电控系统采用CAN总线技术,可以进行快捷的信息传递、数据交换和程序处理,精准高效地控制钻机桅杆操作,并能进行孔深监控、故障诊断和智能服务。如果CAN总线控制系统的通讯部分出现问题,就会影响整机工作状态,严重影响工程进度。本文根据多年经验,就CAN总线维护要点和常见故障常见排查方法进行了总结。
The electric control system of rotary drilling rig adopts CAN bus technology, which can carry out quick information transmission, data exchange and program processing, control rig mast operation accurately and efficiently, and can perform hole depth monitoring, fault diagnosis and intelligent service. If there is a problem with the communication part of the CAN bus control system, it will affect the working status of the whole machine and seriously affect the progress of the project. Based on years of experience, this article summarizes the main points of CAN bus maintenance and common troubleshooting methods.
