摘　　要：针对某新型飞机机电管理计算机自动测试的需求,分析自动测试系统组成和测试方案,深入研究测试系统通信机制。讨论了通信协议消息帧、通信握手机制和消息接收与处理3个关键技术。在Vxworks环境下通过1553B总线测试进行通信机制验证。实验验证,该通信机制能确保系统通信正确可靠,确保整个系统准确高效地完成自动测试任务。To meet the demand for testing the new aviation electromechanical computer automatically, the structure of automatic test system and test scheme are analyzed, and communication mechanism of automatic test system is deeply studied. The message frame, mechanism of communication handshake, message receiving and processing are discussed in detail. The communication mechanism is verified by 1553B test in Vxworks environment. By experimental verification, the communication mechanism can ensure accurate and reliable system communication, which can make sure the system fulfill automatic test task accurately and efficiently.
