矿山多源安全管理系统设计与实现

针对风险管理、设备安全管理、职业卫生管理等模块中涉及的异构系统数据集成问题,运用第三方信息流模型,将系统划分为数据物理存储层、数据逻辑存储层、应用层、控制层及用户层,设计了系统框架,并重点研究了框架中数据逻辑存储层和控制层的实现方法.控制层运用单点登录技术,以中央认证服务（CAS）开源项目为平台,采用服务票根的方式实现了用户身份的统一验证及授权.数据逻辑存储层通过将数据请求过程分为请求、分发、访问、收集、组织及响应六个步骤,通过用户请求和异构系统的业务请求间的变换,并以可扩展标记语言（XML）为标准,将多源数据融合成统一格式的单源数据,实现了异构系统数据集成.通过这种系统框架可以解决异构系统数据集成中的数据提取、写回及安全控制问题,消除矿山安全管理过程中的信息孤岛,提升系统的维护性和扩展性.

Design and implementation of mine multi-source safety management system

Aimed at the heterogeneous system data integration problem in risk management,equipment safety management and occupational health management,based on the model of third information flow,system framework which was divided into data physical storage layer,data logic storage layer,application layer,control layer and user layer was designed.Focused on data logic storage layer and control layer in the framework,the method of implement was researched.In control layer,the technology of single sign-on was used.The Central Authentication Service（CAS） open source project was used as a platform,through the way of service tickets,authentication and authorization of the user identity were achieved.In data logic storage layer,the data request process was divided into request,distribution,access,collection,arrangement and response.In these six steps,user request was transformed into business requests of heterogeneous system,the multi-source data was merged into a single source data which used Extensible Markup Language（XML） to form a unified format,the heterogeneous system data integration was implemented.With this design,the problem of the heterogeneous data integration extraction,write-back and safety control is solved,information islands is eliminated,the maintainability and expandability of system is improved.
