本文介绍一种应用微处理计算机代替传统控制机所用的纸带阅读机的BTR系统,这种系统是使用微处理计算机的软件控制程序及存储功能来模拟纸带阅读机的信息输入,从而可以从上一级计算机直接接受信息。文中重点介绍这种系统的硬件连接、软件摸拟和控制信息输入的程序以及数控加工程序的存取等,并对该系统加以评价。 This paper introduces a microprocessor-based computer control system used in place of the traditional tape reading machine BTR system, this system is the use of micro-computer software control procedures and storage functions to simulate the tape reader’s information input, which can be from Up to a computer directly accept the information. This article focuses on the hardware connection of this system, software simulation and control information input procedures and access to CNC machining programs, and to evaluate the system.
