摘　　要：分布式多空间数据在利用主控计算机进行数据读取中容易受到端口溢出限制,需要进行智能交换读取,选择块传输模式提高数据的读取和传输性能。提出一种基于高速局部总线控制的分布式多空间数据智能交换系统设计方法,系统的开发流程采用多线程自上而下开发方法,开发环境建立在嵌入式Web服务平台中,采用Socket编程构建分布式多空间数据传输的网络协议栈,通过协议栈开发智能交换系统的网络应用程序,采用高速局部总线控制进行数据交换的端口设置和通道控制,通过局部总线送到接收模块,实现智能数据交换。系统测试结果表明,该系统进行分布式多空间数据交换的可靠性较好,提高了总线接收数据块的速率和准确性。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 hi,h-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.
