摘　　要：现有的水利工程测量信息动态更新系统,在传输测量信息时没有最佳的路径概念,采用车轮搜索,导致信息更新所需时间较长,为优化系统运行效率,设计基于多元数据融合设计水利工程测量信息动态更新系统。设计可以增强数据更新速度的芯片作为系统硬件;构造有效路径代价函数,整编水利工程测量多源数据;选择数据传输最短路径;建立最小二乘估计数学模型,引入多元数据融合设计信息更新算法。实验结果显示:在系统更新时间的测试中,面对不同数量的并行服务器,三个对照组用时均高于实验组,可见该系统具备更好的运行效率。The existing dynamic update system of water conservancy engineering measurement information has no optimal path concept when transmitting measurement information.The wheel search leads to a long time required for information update.In order to optimize the operation efficiency of the system,the dynamic update system is designed based on multi-data fusion.It designs a chip that can enhance the data update speed as system hardware;constructs effective path cost function,measures multi-source data,selects the shortest path of data transmission,establishes least squares estimation mathematical model,and introduces multi-data fusion design information update algorithm.The experimental results show that in the test of system update time,the use of three control groups is higher than the experimental group,so the system has better operation efficiency.
