目前工厂企业中所用的数控设备的信息输入,很多是采用纸带输入方式,采用纸带记录信息的优点在于:信息能长期保存、不易丢失,能使数控设备适应恶劣环境。如何使穿孔机输出纸带信息?在以前的国产中小型计算机中,是把穿孔机作为通用的外设连到主机上的,这些机器现大部分已退役。而现在广泛应用的微型计算机中,由于接口数量上的限制,不能直接连接更多的外设。我们设计制作了一个“信号转接器”控制盒,把它直接连到IBM-PC/XT打印机适配
At present, the information input of numerical control equipment used in factories and enterprises is that many of them adopt tape input mode. The advantage of using tape to record information lies in that the information can be stored for a long time and is not easily lost, and the numerical control equipment can be adapted to the harsh environment. How to make the punch output tape information? In the previous domestic small and medium-sized computer, is connected to the piercing machine as a universal peripheral host, most of these machines have been retired. Now widely used microcomputer, due to the limitations of the number of interfaces, you can not directly connect more peripherals. We designed a “signal adapter” control box that connects directly to the IBM-PC / XT printer adapter
