在工业高度发展的今天,计算机控制愈来愈普遍的应用于各种生产过程,由于被控系统日趋庞大和复杂,就出现了许多台计算机联合控制一个大系统的情况,如电网调度系统、铁路航空调度系统、大型钢铁联合企业、石油化工联合企业等等。在大型数据处理系统、情报检索系统中,相距很远的计算机之间直接进行数据传输的任务也愈来愈重,因此,计算机两地通信的实现就成为十分紧迫的需要。为了使目前已分散于各地的形形色色不同规格的大中小型计算机能够可靠方便的进行通信联系,我们利用M6800单板机作为通讯控制器,把远方通信装置与计算机联系起来。充分利用M6800的单板机的处理功能和大中小型计算机数据通道的特点实现两地通信构成统一的计算机控制网络,对被控系统进行综合控制、统一调度形成一个有机的整体,提高系统自动化水平。在两地通信的基础上,可以进一步组成通信网络使多机系统中信息传输更为方便可靠和及时。
In today’s highly industrialized development, computer control is more and more widely used in various production processes. Due to the increasingly large and complex controlled systems, there have been many cases in which computers jointly control a large system such as dispatching system of the power grid, railway Aviation dispatching system, large iron and steel joint ventures, petrochemical complexes and so on. In large-scale data processing systems and information retrieval systems, the task of transmitting data directly between far-away computers is getting heavier and heavier. Therefore, the realization of communication between computers is becoming an urgent need. In order to make the large, small and medium-sized computers of different specifications that have been scattered all over the country can reliably and conveniently communicate with each other, we use the M6800 single-board computer as the communication controller to connect the remote communication device with the computer. Make full use of M6800 single board computer processing functions and features of large, medium and small computer data channels to achieve a unified computer communications network control network, the controlled system for integrated control, unified scheduling to form an organic whole, to improve system automation . Based on the communication between the two places, the communication network can be further formed to make the information transmission in the multi-machine system more convenient, reliable and timely.
