Data exchange between ibm& pc computer and DMP plotter IBM-PC计算机与DMP绘图机的数据交换
The auto test of waveform data and parameters of the controlled objects, Also it can realize the coping of the screen waveform and output ing of the tested parameter reports through printer under VGA mode, and the plotting of the measuring waveform with plotter, etc. 自动测试对象的波形数据与参数,打印机拷贝VGA方式下屏幕波形并输出测试参数报告,绘图仪绘制测量波形等。
This system consists of sonic sonde, magnetic locator sub, gamma ray tool, depth system, surface preprocessing unit, data acquisition interface, PC486 and thermal plotter. 该系统由声波、磁定位和自然伽马下井仪、深度系统、地面预处理电路、数据采集控制接口电路、486微机和热敏绘图仪等构成。
And the link of the mainframe and plotter is the interface unit of plotter. It is responsible for the reception of the image data processed by mainframe applications and sent these image data and control orders to plotter controller to complete image printing work. 而绘图机接口单元就是主机和绘图机的纽带,它负责接收主机应用程序处理过的图像数据和控制命令并发送给绘图机相应的控制器,从而完成图像的打印工作。
In order to increase data transmission rates of the plotter, this paper tailoring a embedded Linux operating system. 本文以提高绘图机数据传输率为目的,通过裁剪普通Linux操作系统,最终获得绘图机需要的嵌入式Linux操作系统。
By using this method in combination with automatic data acquisition and computerized plotter, the test characteristics can be drawn instantaneously on testing ground. 本方法只要再配上测试数据自动采集和计算机绘图,即可在试验现场瞬时绘出试验特性。
By getting the data directly from the database of directly inputing information of geometry and topology of crystal shape, the figure can be displayed on the moniter of computer or draw by plotter. 通过对晶体形态数据库的调用,或直接输入晶体形态测量的几何、拓扑信息,计算机就可在显示器上或绘图仪上输出图形。
The limitations of electronic chart are analysed, and a data sailing system based on paper chart is presented. A mathematical model is established for relationship between chart coord and graph plotter coord. 分析了电子海图的缺陷,提出了用海图绘图仪实现船舶数据航行系统的方案,推导了海图坐标与绘图仪坐标的关系。
In the mean while, the firmware of the hardware board is implemented in company with the design and development of the Windows driver, and at last the task of transferring control information and data flow of plotter through multiple interfaces are completed. 同时,本文对网络接口,USB接口相关协议进行研究,实现了接口板固件程序并完成了Windows驱动程序的设计与开发。最后完成了通过多个接口传送绘图仪控制信息与绘图仪数据流的任务。
