摘　　要：通信设备在研制和生产期间需要进行大量的测试验证工作,自动测试系统可有效地解决这一问题,且在效率、精度、可追溯性上有极大的优势。在实际的测试系统开发中,软件系统需要接入多类型、多厂家、多种型号的测量仪器,对于仪器设备进行有效地兼容、管理和调度是自动测试系统开发中面临的一个重要难点。针对这些具体问题,设计和实现了测量仪器的基于VISA引擎的驱动层,整个架构采用分层模型,遵循高内聚、低耦合的设计原则,具有较强的复用性和扩展性。During the development and production of communication equipment,a lot of testing and research work is required.The automatic test system can effectively solve this problem,and has great advantages in efficiency,accuracy and traceability.In the actual test system development,the software system needs to be connected to multi-type,multi-manufacturer,and multi-model measuring instruments.Effective compatibility,management and scheduling of instruments and equipment is an important difficulty in the development of automatic test systems.In response to these specific problems,the VISA engine-based driver layer of the measuring instrument is designed and implemented.The whole architecture adopts a layered model,follows the design principles of high cohesion and low coupling,and has strong reusability and scalability.
