内燃机车逻辑控制器

Logic controller for diesel locomotive

以东风４Ｂ型内燃机车控制电路为例，介绍了一种用８０９８单片机实现的逻辑控制单元──内燃机车逻辑控制器，用于取代传统的由继电器控制电路实现的布线逻辑控制方式，实现机车控制电路的各种控制功能．重点介绍了内燃机车逻辑控制器的硬件、软件设计．

Taking the control circuit of DF4B diesel locomotive for xample, the paper introduced a logic control unit realized by Intel 8098 for diesel locomotive, which is to replace the traditional wiring logic control realized by relay control circuits, and thus to implement various control functions for locomotive control circuits. Introduction focuses on design of hardwares and softwares for diesel locomotive logic controller.
