面向空间信息的数据通信协议的设计与实现

摘要

In view of the fact that traditional geographic information system lacks a method to acquire the real-time data of sen-sors,it is difficult to display the real-time data of sensors by using the traditional means of geographic information system.For this problem,the characteristics of the sensor data communication protocol were investigated,the characteristics of geographic information spatial operations were combined,then the data communication protocol for spatial information was designed.The real-time communication method was used to solve the problem of poor real-time performance in the display of sensor data in the traditional geographic information system.Based on the data communication protocol for spatial information,the corresponding server operation and response model was designed.The feasibility of the data communication protocol for spatial information is verified in a remote electric meter monitoring software.%鉴于传统地理信息系统缺少一种对传感器实时数据获取的方法,利用传统地理信息系统的手段很难进行传感器的实时展示.针对此问题,研究传感器数据通信协议的特征,结合地理信息空间操作的特点,设计面向空间信息的数据通信协议,采用实时通信的方式解决传统地理信息系统在展示传感器数据方面实时性差的问题.根据面向空间信息的数据通信协议,设计与之对应的服务端操作与响应模型.在远程电表监控软件中验证了该协议的可行性.
