分布式多空间数据智能交换系统设计
Design of intelligent exchange system for distributed multi spatial data
摘要
Abstract
When the master computer is used to carry out data reading,the distributed multi spatial data is vulnerable to restriction on port overflow. Therefore,the intelligent exchange reading is needed,and the block transfer mode should be select-ed to improve the data acquisition and transmission performance. A design method of distributed multi spatial data intelligent ex-change system based on high-speed local bus control is put forward. The multi-thread top-down development method is adopted in the system development process. The development environment is based on the embedded Web service platform. Socket pro-gramming is used to build the network protocol stack for distributed multi spatial data transmission. The protocol stack is em-ployed to develop the network application program of intelligent exchange system. The high-speed local bus control is adopted to set the data exchange port and channel control. The data is sent to the receiving module through the local bus to realize the intel-ligent data exchange. The system test results show that the system has better reliability for the distributed multi spatial data ex-change,and can improve the speed and accuracy of the bus to receive data blocks.关键词
