| 摘 要： | 1 通讯方式 不同类型的计算机系统之间数据通讯,可为我们的图象信息处理开拓资源共享的广阔领域。目前,引进或国内研制的计算机种类繁多,功能各异。VAX系列的通讯有多种类型,向上可以与卫星地面站相连形成全球性卫星通讯,向下可以与每个工作站连接成为高效率的计算机网络,对于一个大学的通用型图象处理系统,若能与各种微机直接传送图象数字化后以及各种处理后所得出的数据和文件,无疑为图象处理、模式识别的研究,教学与实验提供了灵活、实用的有利条件。

| Abstract: | Researches on a system with super-minicomputer VAX-11 and Model 75 array processor have been carried out in the past few years. Many people are now interested in the application of microcomputer in image processing. To share the resources of image data and programs, communication between different types of computers is needed.This paper describes the modulation eliminator and the method of direct connection used; Not only is a rapid data transfer permitted, but also the line noise can be eliminated. In asynchronous communication, the setting of an appropriate bit nu-m ber is of crucial importance to giving an optimal transfer speed. Softwares have been developed for VAX-11 and IBM-PC to perform interactive communication. |
