摘要
利用USB总线通用和即插即用的特点，研制了基于USB总线接口的ARINC429总线测试仪，该总线测试仪利用USB总线来收发ARINC429总线数据，测试计算机通过USB总线便可与各种ARINC429总线的设备进行数据通信，使ARINC429总线测试更加方便快捷.文中详细介绍了总线测试仪的系统结构，给出了硬件系统设计思想，并详细讨论了测试仪软件系统结构、数据结构以及应用程序接口调用流程.
Universal Serial Bus （USB） is a widely used hardware interface for attaching computer peripheral devices. The design of USB aims at removing the need for adding separate expansion cards into the computer, and improving plugand-play capabilities by allowing devices to be hot swapped or added to the system without rebooting the computer. USB- based ARINCA29 bus tester has been developped. A computer connected with the tester can communicate with various ARINC429 bus devices. The use of ARINCA29 bus tester can make tesing of ARINC429 easy and fast. The architecture of the tester is introduced. The design of its hardare and software architecture, data structure, Application Programming Interface （API） and flow charts for the use of API are also discussed.
