这是一个用软件实现的键盘显示系统。它的特点是:显示设备不自带存贮器;键盘显示的工作主要由程序实现。因此,这一系统的硬件部分结构简单,造价低,易于实现。这个项目是用了约半年时间研制成功的。经过半年来的投入使用,说明此系统除可上机操作使用外,还在心电图自动诊断、云图处理、地震资料整理、船体放样曲线计算以及图象输入等方面的显示应用上,取得了初步成绩。719数字电子计算机的键盘显示装置由显示器,逻 This is a software implementation of the keyboard display system. It is characterized by: display device does not bring memory; keyboard display work mainly by the program. Therefore, the hardware part of the system is simple in structure, low in cost and easy to implement. This project was developed in about half a year. After six months of operation, it shows that this system has not only been put into operation on the machine, but also achieved preliminary results in the display applications of automatic diagnosis of electrocardiogram, cloud image processing, seismic data processing, calculation of hull loft curve and image input . 719 digital electronic computer keyboard display by the monitor, logic
