针对DF型内燃机车电气线路、电器柜、操纵台基本采用散线连接而导致故障率高、难调试等缺陷,采用非常成熟的微型可编程逻辑控制器PLC控制技术,实现了DF型内燃机车各电器元件的逻辑控制与状态显示、机车故障保护与显示、柴油机调速、微机励磁、辅助发电等功能,并将机车大把槽线简化为电器柜与两操纵台之间的双备份网络连线。
For the DF diesel locomotive electrical lines, electrical cabinets, control the basic use of loose wires connected to lead to high failure rate, difficult to debug and other defects, the use of very mature programmable logic controller PLC control technology to achieve the DF diesel locomotive The electrical components of the logic control and status display, locomotive fault protection and display, diesel speed control, computer excitation, auxiliary power generation and other functions, and locomotive slot line simplified as two electrical cabinets and dual backup network between the console connection .
