目前,微型计算机在厂矿企业计划管理中的应用日益广泛,但一般还是单机使用。进一步开发一套实用并且易于推广的数据通信网是十分必要的。本文介绍了一套适合厂矿企业使用的、能与各类微型机联机的多终端数据通信网,现已正常运行,效果良好。本通信网可用于数据采集、监测、控制等其它微机应用项目。 At present, the application of microcomputer in plan management of factories and mines is more and more widely, but generally it is used alone. To further develop a practical and easy to promote the data communication network is very necessary. This article introduces a set of multi-terminal data communication network suitable for factories and mines, which can be connected with all kinds of micro-computers. Now it works well and works well. The communication network can be used for data acquisition, monitoring, control and other computer applications.
