摘　　要：简要介绍了LDB型半变频驱动钻机的一种新式整车逻辑编程电控系统的网络总线构成,此新型总线布局将原有钻机系统的液气路PLC逻辑控制中枢系统与变频器驱动转盘电机的闭环控制运算中枢系统通过Profibus-DP总线串联在了一起,经过硬件组态,将两个控制中枢融为一个。避免了两个中枢在信息交换过程中出现的干扰与其它人为故障;同时在实际钻机作业过程中将两方面的控制更为紧密的通过软件无缝的联系在了一起,提供给司钻人员更多的方便与安全保障。A brief introduction is given to a new network bus constitution about the entire-vehicle logic programming electric control system of LDB semi-variable frequency drive rig. This new bus constitution connects two central systems in series through Profibus DP bus, one belonging to the liquid path logic control （PLC） of existing drilling machine, the other belonging to closed control calcu- lation of transducer driving rotary motor. Then through hardware constitution, two control central systems are integrated into one cen- tral system, which avoids the disturbance and other man-made defaults appearing in the process of information exchanges of two cen- tral systems. Meanwhile, in the actual operation of drilling machines, connecting two control systems closely via the seamless software can provide drilling workers with more convenience and safety control.
