Abstract: This paper discusses how to design one kind of embedded system according to the interface of vehicle reinforced computer, describs the design requirement, function block and software flowchart. It provides new idea for testing the interface of vehicle reinforced computer. The equipment designed provides some kinds of interface that is used normally in vehicle reinforced computer, and it has the benefit of simple made up, convenient usage, low cost, and can replace all kinds of discrete cards that are used in test before.

Key words: embedded system, test equipment, interface

摘要： 论述了针对车载加固计算机的各种接口设计的嵌入式测试系统。描述了系统的设计需求、功能框图以及软件的设计流程。该设计为车载加固计算机的各种接口测试提供了新的思路。设计实现了使用一台便携式测试设备提供车载加固计算机的各种常用接口测试功能。该设备具有性能稳定、构成简单、方便易用、成本低廉的特点，可以代替以往测试中所使用的各种分离卡件。
