|
摘要
分析了当前地质数据处理共享服务的现状与问题,提出了一种基于消息调度机制的分布式地质服务体系,该架构是地质服务体系的新尝试,初步解决了地质数据处理服务共享中的复用性问题。在简要介绍消息调度机制的概念和应用模式的基础上,基于发布/订阅模式设计了地质数据处理服务共享应用架构,实现了地质数据处理算法库的封装、地质数据服务共享的发布、描述了地质数据处理消息的流程,并以流程化地质数据处理在线服务为示例,简述了流程的设计和执行。实践证明,该体系能够复用已有的地质数据处理应用软件,满足互联网应用系统的快速开发的需要,节省算法重新编码和服务生产,可以在地质数据处理服务中推广使用。
This paper analyzes the current situation and existing problems of geological data processing services,and proposes a distributed geological service system based on message scheduling mechanism.The architecture is a new attempt of the geological service system,and it preliminarily solves the reuse problem of geological data services and processing services.Firstly,the concept of message mechanism and application model is introduced;secondly,geological processing service application architecture of message scheduling mechanism is designed and the geological algorithm library service package as well as geological data sharing service is realized,and the geological message processing process is described.Lastly,an online processing services flow is demonstrated.Practice has proved that the scheduling mechanism can greatly reuse geological data services and processing services so as to meet the rapid development of Internet application system to save algorithm re-encoding and service production,so it can be widely used in geological data processing services.
