铁路勘察设计电气化接触网专业在设计过程中,涉及专业、人员、数据量众多。为提高不同专业间协同设计及具体区间辅助设计效率,确保项目流程的可追溯性,实现多专业数据共享,特开发了接触网设计平台及基础数据库系统。通过对电气化接触网专业业务流程的分析,设计项目管理流程,结合短信提醒与中心数据库管理技术,实现了项目流程的管理、监控与数据共享。从接触网辅助设计的数据获取,中期数据处理、工程设计约束及工程数量统计等方面进行分析、归纳和简化,采用参数化的设计方法,建立了对应辅助设计子系统的数学模型,并采用“用户-角色-权限”模式的访问控制机制保证了应用过程中数据的安全性。
Railway survey and design electrification catenary professional in the design process, involving professionals, staff, a large amount of data. In order to improve the efficiency of collaborative design and specific interval aided design in different disciplines, ensure the traceability of project processes and achieve multi-professional data sharing, a contact network design platform and a basic database system have been specially developed. Through the analysis of the professional business process of the electrified contact network, the project management process is designed, and the management, monitoring and data sharing of the project process are realized by combining the SMS reminder and the central database management technology. This paper analyzes, summarizes and simplifies the data acquisition, mid-term data processing, engineering design constraints and engineering quantity statistics of catenary assistant design, and adopts the parametric design method to establish the mathematical model corresponding to the auxiliary design subsystem and adopts The “user-role-permission” mode of access control guarantees the security of the data in the application.
