GP-IB 标准是通用接口母线系统国际标准的简称。这个标准的最初目的,是使不同国家不同厂家生产的仪器,通过标准接口母线的连接,都能组成一个自动测试系统,消除以往每次组建系统时都要设计专门接口的重复劳动。微处理器的发展促进了这个标准的推广,目前它的应用早已超出自动测试系统的范围。本文介绍这个标准,并结合微处理器技术的发展,提出实现这种标准接口的合理建议。
The GP-IB standard is an abbreviation of International Standard for Common Interface Bus System. The original purpose of this standard is to make the instruments produced by different manufacturers in different countries to form an automatic test system through the connection of standard interface buses, eliminating the repetitive work of designing specialized interfaces for each system in the past. The development of the microprocessor has promoted the popularization of this standard, and its application has already exceeded the range of the automatic test system at present. This article describes this standard, combined with the development of microprocessor technology, put forward reasonable proposals to achieve such a standard interface.
