一种适用于配电网抢修的移动终端与服务器交互机制

An Interaction Mechanism between Mobile Terminals and Server for Emergency Maintenance of Distribution Networks

平板电脑等移动终端在配电网抢修业务中的应用越来越受到业内人士关注,当前已经在天津、成都、重庆等城市开展试点工作。试点中发现移动通信网络不稳定,易发生丢单、工单状态不一致等问题。为此,本文分析了移动通信网络现状和配电网抢修的业务需求,并基于长连接技术,设计了一种高可靠的移动终端与服务器交互机制。本文提出的数据交互机制已经应用于重庆配电网抢修业务,并取得了良好的应用效果。

Tablets and other intelligent mobile terminals are paid more and more attention in emergency maintenance of distribution networks, pilot projects have been carried out in some cities including Tianjin, Chengdu and Chongqing. It was found that mobile communication network are instable and easy to incur problems such as information loss and inconsistent state of order in the pilot projects. In order to solve these problems, a mechanism that can ensure accurate reliable information interaction between the intelligent mobile terminals and server is proposed. First, the present situation of mobile communication network and the requirements of distribution network emergency maintenance are analyzed. Then, a highly reliable interaction mechanism between intelligent mobile terminals and server based on the HTTP persistent connection technology are designed. The proposed mechanism has been applied to distribution network emergency maintenance in Chongqing, and good application effect has been achieved.
