摘　　要：分布式数据采集系统各子系统间的连接测试,需要专门的接口测试工具。随着私有协议的广泛使用,设备生产、维修中的调试测试问题也大大增加。这些问题往往无法使用传统的通用协议测试仪器进行测试,本文提出一种由测试模块加PC机方式构成专用接口测试系统的开发策略,并且重点介绍基于ARM的测试模块设计实现方法。文章分析了测试模块的接口特性、基本结构和软件流程,随后探讨了其与PC组成测试系统的应用方法。实验结果表明,该测试系统较好地满足了专用接口测试需求。这种测试模块加PC机构成简便系统的开发思路,为此类专用接口测试系统的快速开发提供了一种途径。As the use of private protocols becomes popular in distributed data acquisition system, it is urgent to test interfaces of these systems. The interfaces cannot be tested by general communication protocol testing equipments, so a simple strategy of how to develop an efficient custom interface testing system with a testing module based on PC is proposed. In this paper, we focus on the design and implementation of how to realize an interface testing module based on ARM. Analyses of the interface characteristics, basic structure and software processes of the interface testing module, and application method of interface testing with the PC and the interface testing module, are discussed. Experimental results show that the custom interface testing system well meets the testing requirements. This proposes a way to do a rapid development of custom interface testing systems.
