摘要
机车微机控制系统是一个信息量大、控制功能比较复杂的多CPU系统。主CPU与控制对象间需要交换大量的模拟量和数字量信息,主CPU与其它CPU间也必须交换信息。本文介绍了这两方面的信息交换技术。所述方法也适用于其它多CPU的微机系统。
Locomotive microcomputer system is a multi-CPC system with n great amount of information and complicated control functions. A large number of analogue & digital Quantities information need to be exchanged between main CPU and its control object, as well as between main CPU and other CPU. The paper introduces information exchange techniques in the two aspects, which can also be adapted to other multi-CPU microcomputer systems.
