接入层的电压监测代理装置和电压监测装置之间数据传输关系如图2所示。电压监测代理装置实现电压监测信息的汇聚、转发及主站控制命令的下发。电压监测代理装置，为一种能够在一个局部范围内管理和协同各类电压监测装置、汇集各类电压监测数据、并替代电压监测装置与主站系统进行安全双向数据通信的代理装置。电压监测代理装置包括数据接收及处理模块和控制命令下发模块，数据接收及处理模块汇集其所辖范围内的电压监测装置采集的电压监测数据并以一种统一的方式将数据传输至主站，控制命令下发模块则转发主站层的参数配置、远程升级及数据召唤等控制命令。电压监测代理装置可接入不同类型、不同厂家甚至不同变电/用户站上的一组电压监测装置，从而实现各类电压监测装置的标准化接入。
电压监测主站是能接入各类电压监测信息、并进行集中存储、统一处理和应用的计算机系统。如图3所示，电压监测主站包括电压数据接入服务模块、电压数据处理模块、电压数据库以及电压数据服务和各类供电电压数据应用功能模块。其中，电压数据接入服务模块是主站的集中关口，接收并解析电压监测代理转发的电压数据、接收并解析调度和营销业务等横向集成系统的电压数据、转发主站对电压监测装置发出的控制命令，对进出主站系统的信息进行日志记录。电压数据处理模块在供电电压数据集中到数据库中后对供电电压数据进行二次加工，利用日月合格率统计数据计算监测点季度、年度合格率以及各级单位的综合供电电压合格率、分类电压合格率，同时具备异常信息提取、干扰过滤等功能。电压数据库为两级集中存储、由省公司数据库和总部数据库组成，基于企业级关系型数据库构建，按照分钟级数据的采集频率，采用分区分表的存储技术来保证各类数据库操作的响应时间要求以及数据维护要求。省公司数据库存储所有监测点的分钟平均值数据和日月季年统计数据、综合供电电压合格率及分类电压合格率数据；总部数据库保存统计数据，包括保存各省公司所 有监测点的日月季年统计数据和省、地市、县级供电企业综合供电电压合格率、分类电压合格率。
为了实现电压数据的安全接入，本发明还在电压监测装置中内置了安全芯片。如图4所示，电压监测装置通过安全芯片与主站系统侧之间通过无线专网安全接入平台建立双向加密通道，实现采集终端身份认证、加密传输，最终实现外网的电压数据安全接入。
基于以上两级集中部署的供电电压自动采集系统的供电电压自动采集方法，包括以下步骤：
1)监测时，由电压监测装置对被监测电压进行有效值采样，并以1min平均值作为被监测系统的即时实际运行电压，根据电压上下限值统计电压日合格率及月合格率，并以统一将数据加密后传输至电压监测代理装置。
2)电压监测代理装置汇集其所辖范围内的电压监测装置采集的电压监测数据并统一将数据传输至电压监测主站，并转发电压监测主站的控制命令，所述控制命令包括参数配置、远程升级及数据召唤。
3)电压监测主站接收并解析电压监测代理装置转发的电压数据，接收并解析包括调度和营销系统在内的横向集成系统的电压数据，并对电压监测装置发出控制命令，对进出主站系统的信息进行日志记录。
4)在供电电压数据集中到电压数据库中后，电压监测主站对供电电压数据进行二次加工，利用日月合格率统计数据计算监测点季度、年度合格率以及各级单位的综合供电电压合格率、分类电压合格率。
上述方法中，电压监测主站可以与调度系统自动化集成，通过E语言文件传输的方式统一与调度系统传送电压数据，从而适应调度系统在控制区存在安全隔离装置。而对于营销业务系统，则可以采用WebService方式格式传送电压数据。以上方式可以统一的接口实现信息接入及共享，节省通信及信息资源，保证系统稳定性的同时强化系统的集成能力，实现信息共享。
省公司数据库和总部数据库之间可以采用远程分布式数据获取和数据交换两种方式进行数据沟通。可以根据总部管理层用户对业务关注度对业务数据进行分类，并对于关注度较高的业务数据可以通过数据交换进行本地存储及应用，而对于关注度较低的信息则可以通过页面嵌入技术实现远程访问分布式数据获取。两者的统一可以最为合理地实现系统功能。
虽然本发明已以较佳实施例公开如上，但实施例并不是用来限定本发明的。在不脱离本发明之精神和范围内，所做的任何等效变化或润饰，同样属于本发明之保护范围。因此 本发明的保护范围应当以本申请的权利要求所界定的内容为标准。
