一九八四年六月笔者赴英参加了第二次国际仪表与控制对话会议,并参观了PROMECON 展览会。本文想仅就在展览会上所看到的由美国霍尼韦尔公司最新推出的TDC3000控制系统做一简要介绍。众所周知,单元组合式仪表不能适应规模大的系统;而计算机的集中控制又会造成计算机一出故障会带来它所控制的几十个或几百个回路失控的危险。为解决这些矛盾,亦
In June 1984, the author attended the second international instrument and control dialogue meeting in the UK and visited the PROMECON exhibition. This article will only be seen at the exhibition by the United States Honeywell’s latest TDC3000 control system to make a brief introduction. It is well-known that a cell-combination meter can not accommodate a large-scale system; and the centralized control of a computer, in turn, can result in the computer failing in danger of losing control of dozens or hundreds of circuits it controls. To solve these contradictions, too
