一个直接存取Internet节点数据的DBMS原型

ALGORITHM AND IMPLEMENTATION FOR IMPROVING PRECISION OF GAS FLOW MEASURING

基于现存ＤＢＭＳ和Ｉｎｔｅｒｎｅｔ数据模型的特点和互补性，本文提出了一个直接存取Ｉｎｔｅｒｎｅｔ节点数据的ＤＢＭＳ原型ＷｅｂＨＢａｓｅ，分析了ＷｅｂＨＢａｓｅ的特殊任务、主要难点及特殊解决方法，基于ＷｅｂＨＢａｓｅ的预研经验，提出了Ｗｅｂ模型与ＤＢＭＳ各自改革、互相靠近，逐步融合，实现未来ＷｅｂＤＢＭＳ的若干建议。

In order to make full use of resources of gas flow measuring and controlling networks.This paper analyzes the measure algorithm of throttle gas fluid flow with temperature and pressure compensation,and proposes a method of improving algorithm's precision that utilize master console of network for inquiring data and transmitting the last compensation parameters.The flow chart of the proposed method is given.The algorithm is simulated and the results are satisfactory.
