一种可配置数据交互流程的嵌入式总线接口测试系统设计与实现

在航空、航天、汽车、通信等综合电子系统中，嵌入式软件的占比越来越高，实现的功能和数据交互流程也越来越复杂。在嵌入式软件测试中，现有基于总线通信的半实物仿真系统缺乏或不能便捷提供交互流程的模拟能力。针对该问题，提出了一种基于总线通信、总线数据收发，以及数据收发流程控制的嵌入式总线接口测试系统设计，可适应MIL-STD-1553B总线、以太网、RS232/422/485总线、CAN总线、ARNIC429总线等，具备测试用例设计、自动化执行、接收数据解析等功能，并阐述了其系统设计、软件设计、重要功能设计实现及试验分析。该系统已进行原型设计，并已在多个型号项目中应用，提高了操作人员对测试环境搭建的效率，缩短了为项目定制开发仿真系统的时间。

Design and Implementation of An Embedded Bus Interface Test SystemBased on Configurable Data Interaction Flow

In the integrated electronic systems of aviation, aerospace, automobile, communication, etc., the proportion of embedded software is higher and higher, and the functions and data interaction processes are more and more complex. In the embedded software testing, the existing hardware in the loop simulation system based on bus communication lacks or cannot provide the simulation ability of interactive process conveniently. Aiming at this problem, presents a design of embedded bus interface test system based on bus communication, bus data receiving and sending, and data receiving and sending process control, which can adapt to MIL-STD-1553B bus, Ethernet, RS232 / 422 / 485 bus, can bus, arnic429 bus, etc., and has the functions of test case design, automatic execution, receiving data analysis, etc., and describes its system Design, software design, important function design realization and test analysis. The system has been designed in prototype and applied in many types of projects, which improves the efficiency of operators to build test environment and shortens the time of developing simulation system for project customization.
