一、概述计量器具在地铁运营中具有非常重要的作用,是保障安全运行的关键仪器,是维护设备的重要工具。对于地铁来说,由于器具数量较多、管理地点分散、应用范围广以及计量器具本身具有的动态管理特点,使得日常管理工作量很大,而且容易出错。同时由于其计量器具数量巨大,周检计划的动态数据维护量很大。但是,目前大部分工作仍使用Excel手工处理,迫切需要采用信息化手段管理现有计量器具,并逐步优化升级。二、系统模式我公司采用的地铁计量器具管理系统的模式是基于J2EE的企业级架构模式。J2EE平台构建整个应用系统,采用Java技术及XML技术,平台采用基于B/S的多层架构 First, an overview Measuring instruments in the subway operation has a very important role, is to ensure the safe operation of the key instruments, equipment maintenance is an important tool. For the subway, due to the large number of appliances, scattered management sites, a wide range of applications and the dynamic management of measuring instruments itself features, making the daily management of a large amount of work, and prone to error. At the same time due to the huge number of measuring instruments, the weekly inspection plans to maintain a large amount of dynamic data. However, at present, most of the work is still handled manually using Excel. There is an urgent need to use information technology to manage existing measuring instruments and to gradually optimize and upgrade them. Second, the system model I used the company’s metro management system model is based on J2EE enterprise-class architecture model. J2EE platform to build the entire application system, using Java technology and XML technology, the platform based on B / S multi-tier architecture
