摘　　要：为解决传统的组态软件数据库数据定位时,因波动性较大会导致定位效果差、资源空间占用率大的问题,在Web环境中,将数据库中的数据快速分配到传输平台,再将数据资源以最小量的形式分配到数据采集网络链路中;然后,在网络节点之间的数据链路中测量数据距离,使数据通过最短链路从而实现数据定位。结果表明,基于Web的定位算法可以有效降低定位过程的波动性,有效定位数据量达到了90%,且定位过程的空间资源占用率最高仅为8.5%。The traditional configuration software database data location,due to large fluctuation levels will lead to problems such as poor positioning effect,resource space occupation rate.In the network environment,the data in the database was quickly allocated to the transmission platform,and then the data resources were allocated to the data acquisition network link in the form of the minimum amount.Next,the data distance was measured in the data link between the network nodes,so that the data could pass through the shortest link to achieve data positioning.The results showed that the web-based positioning algorithm could effectively reduce the volatility of the positioning process,the amount of effective positioning data was up to 90%,and the highest occupancy rate of space resources in the positioning process was only 8.5%.
