【摘要】：在许多大型工业用户,因为电站监控系统的维护人员有限,系统基本处于瘫痪状态,同时随着节能降损,电能质量管理等日益得到重视,电站监控系统的可用性成为瓶颈。设计与研发一套小型化、免维护、少配置的监控系统成为一个很重要的课题。嵌入式系统的发展为本课题的开展提供了很好的基础。本课题就是在这个背景下开展的,系统采用通用的嵌入式平台,融合嵌入式数据采集与控制系统、嵌入式实时数据库、嵌入式关系数据库于一体,配合通用的电力仪表,设计与实现了一个嵌入式电站监控平台。设计与研发的成果具有较大的社会价值与经济价值。本人在系统开发过程中所做的主要工作如下： 1.嵌入式监控平台的总体设计工作。嵌入式监控系统是针对中、小型配电站开发的,用于电力设备的监测与能量管理,要求人机界面简单实用、易于掌握。用户可以通过本系统的实时参数显示功能实现对关键配电回路电气运行状况的远方监视,通过本系统生成全电量、电能、分时计量、谐波畸变率等各种运行分析报表。主要设计内容包括系统的总体架构,系统的数据流分析,运行设计以及系统的关系数据库模型。 2.实时数据库系统的设计与研发。实时数据库系统是嵌入式监控系统的核心技术,它根据实时库的模式自动加载关系数据库的数据,并建立相应的B树数据索引,并通过接口库对外提供统一的实时库访问服务。通过接口库的封装,中间的繁杂的通信被很好的屏蔽起来,调用者仅需要设置访问数据库的IP地址,就如操作本地数据一样可以操作各个实时服务器上的数据。 3.采用本文所述系统对某风景区10KV电站进行了项目设计和实施。
[Abstract]:In many large - scale industrial users , because the maintenance personnel of the power station monitoring system are limited , the system is basically in a paralyzed state , and the availability of the power station monitoring system becomes a bottleneck along with the energy - saving and loss - loss , the power quality management and the like . The design and development of a monitoring system which is small in size , maintenance - free and less - configuration becomes an important subject . The development of the embedded system provides a good basis for the development of the subject . The project is carried out in this background , the system adopts the general embedded platform , combines the embedded data acquisition and control system , the embedded real - time database and the embedded relational database into a whole , cooperated with the universal power meter , designed and realized an embedded power station monitoring platform . The design and development results have great social value and economic value . The main tasks I have done in the development of the system are as follows : 1 . The overall design of the embedded monitoring platform . The embedded monitoring system is developed for the middle - and small - sized power stations , which is used for monitoring and energy management of the power equipment . It requires the human - machine interface to be simple and practical and easy to master . The user can realize the remote monitoring of the electric health of the key distribution circuit through the real - time parameter display function of the system . The main design contents include the overall architecture of the system , the data flow analysis , the running design and the relational database model of the system . 2 . The design and development of the real - time database system . The real - time database system is the core technology of the embedded monitoring system . It automatically loads the data of the relational database according to the mode of the real - time library , establishes the corresponding B - tree data index , and provides the unified real - time library access service through the interface library . 3 . Using the system described in this paper , the project design and implementation of 10KV power station in a scenic spot is carried out .
