电动车组电气配线工艺设计系统开发关键技术研究

针对公司工艺设计部电气配线组的电动车组电气配线工艺设计系统开发中的若干关键技术进行详细描述,包括用户池与锁池并发处理技术、数据库扩展值对技术、数据库索引优化技术。通过这些关键技术的实施,解决了B/S模式下多用户并发数据操作请求情况下,数据无法保持一致性以及完整性的固有缺陷,大规模数据量情况下多条件数据查询数据库响应速度较慢这一技术难题。

Study on the Key Technology of the EMU Electric Wiring System Process Design System

In this paper,the design of the electric wiring system of EMU(Electric Multiple Units) of CSR Qingdao Sifang Co.,Ltd is introduced completely.There are three key points which are described in the paper.They are userpool and lockpool synchroniz accessing strategy,database extended value-pair strategy and database index optimization strategy.Deployed these strategies,we can make a perfect solution for the data consistency and integrality in the B/S software design pattern,and we can shorten the database accessing time response during large scale data reading and writing to the database.
