摘要
针对电子仪器自动检定/校准测试软件设备无关性和代码重用性的问题,提出了基于通用接口层的检定/校准测试系统体系结构,通用接口使仪器设备的控制细节对上层测试控制程序透明,简化了上层测试流程软件的开发,提高了代码的可重用性.基于VISA库设计实现了通用接口层功能,并通过组建兼容GPIB、RS232、USB、LAN接口仪器的检定/校准系统实施仪器的检定操作与通信控制,验证了通用接口的功能和该体系结构的可行性.
This paper provides a general-purpose interface based software architecture, which aiming at the issues of code reusability and device-independent of test software for automatic verifying/calibrating electronic instruments. The general-purpose interface makes the detail of device control transparent to the upper test-control application, and simplified the development of the test-control flow software, and improves the code reusability. Based on the VISA, the paper implements the function of this general-purpose layer in the architecture. Based on the GPIB, RS232, USB and LAN buses, experiments are employed to verify the functionality and feasibility of the whole framework.
