摘　　要：构建大型环境地理信息系统在提高环境保护的智能性方面具有重要意义,提出基于嵌入式ARM的大型环境地理信息系统设计方法。系统分为环境地理信息采集层、信息管理控制层和信息输出层,采用多线程的套接字技术进行环境信息过滤,采用TCP/IP以太网技术构建大型环境地理信息管理的信息资源共享模块,在云计算环境中进行地理信息的在线查询和资源调度。以嵌入式ARM9TDMI为内核微处理器,实现大型环境地理信息系统的软件开发,用ARM片上控制器来完成地理信息系统的读写和数据访问操作。系统测试结果表明,设计的大型环境地理信息系统对环境地理信息存储和调度的吞吐性能较好,数据输出的误码较低,信息系统具有很好的人工智能性。The construction of geographic information system in the large-scale environments has great importance for improving the intelligence of environmental protection.This paper puts forward a design method of geographic information system for large-scale environment based on embedded ARM.The system is divided into environmental geographic information collection,information management and information control layer and output layer,socket technology with multi thread environment information filtering the construction of geographic information management module of large environment using TCP/IP Ethernet technology information resources sharing,online calculation of geographic information query and resource scheduling in cloud environment.Microprocessor based on embedded ARM9 TDMI software,the development of geographic information system for large scale environment,using the controller ARM chip to complete the geographic information system and data read and write access the operation of the system.The test results show that the large-scale environmental geographic information system designed in this paper is for environmental geographic information storage.The throughput of storage and dispatching is better,and the error of data output is low,so the information system has good artificial intelligence.
