【摘要】：随着智能电网的快速发展,全国安装的电能表迅速增加并且分布广泛,将电能表带回实验室检测的方式已经满足不了生产需求,电能表现场校验仪应运而生。电能表数量庞大而且目前对电能表现场校验检测的管理机制尚不完善,在现场校验电能表的过程中发现了三个问题:一是现场校验电能表时经常出现假检、漏检的问题;二是工作人员在抄录电能表信息时会存在抄错的问题;三是会出现数据时效性差甚至数据丢失的问题。基于以上情况,在了解电能表现场校验仪发展后,本课题做了以下方面的研究:(1)研究了现场校验电能表经常出现假检、漏检的问题。将GPS定位技术应用于电能表现场校验仪,实现对校验地区的准确定位。(2)研究了抄录电能表信息时会存在抄错的问题。将扫描条形码技术应用于电能表现场校验仪,实现对电能表信息快速、准确地采集。(3)研究了数据时效性差甚至数据丢失的问题。将无线通信技术应用于电能表现场校验仪,实现电能表现场校验仪与远端服务器无线通信,提高数据时效性和稳定性。(4)研究了具有定位功能、校验电能表功能、扫描电能表条形码功能和将数据实时上传到远端服务器功能的系统方案,完成硬件平台搭建和软件设计。(5)设计开发具有扫描功能和通信功能的手机APP。综上所述,本课题研究与设计的智能电能表校验仪,在现场对电能表进行校验的同时,GPS定位系统对校验地区准确定位,通过WiFi模块与手机建立无线通信将校验结果和定位坐标发送到手机。手机扫描条形码获取电能表基本信息,通过移动数据网络将电能表基本信息、校验结果和定位信息传输到远端服务器,生成电能表状况的数据库并依此数据库完成校表、换表计划,提升工作效率,有效地解决了假检、漏检、抄表错误和数据时效性差甚至数据丢失的问题。
[Abstract]:With the rapid development of smart grid, the number of watt-hour meters installed in China is increasing rapidly and widely distributed. The way of bringing the watt-hour meters back to the laboratory can not meet the demand of production, so the on-site verification instrument of watt-hour meters has emerged. The quantity of watt-hour meter is huge and the management mechanism of on-site checking and testing of watt-hour meter is not perfect at present. Three problems have been found in the course of on-site checking of watt-hour meter: first, the problem of false check and missed check often occurs when checking the watt-hour meter on the spot; The second problem is that the staff will copy the watt-hour meter information wrong, and the third is that the data time efficiency is poor or even the data is lost. Based on the above situation, after understanding the development of Watt-hour meter field calibrator, this subject has done the following research: (1) the problem of false check and missed check is studied. The GPS positioning technology is applied to the field calibrator of the electric energy meter to realize the accurate location of the calibrated area. (2) the problem of copying the information of the electric energy meter is studied. The technology of scanning bar code is applied to the field calibrator of watt-hour meter, which can collect the information of watt-hour meter quickly and accurately. (3) the problem of data timeliness and even data loss is studied. The wireless communication technology is applied to the field calibrator of the watt-hour meter to realize the wireless communication between the on-site calibrator of the watt-hour meter and the remote server, so as to improve the timeliness and stability of the data. (4) the function of locating and verifying the watt-hour meter is studied. The system scheme of scanning bar code function and uploading data to remote server in real time completes hardware platform construction and software design. (5) A mobile phone app with scanning function and communication function is designed and developed. To sum up, this research and design of intelligent Watt-hour meter calibrator, in the field to check the Watt-hour meter, at the same time the GPS positioning system to accurately locate the calibration area, Establish wireless communication with mobile phone through WiFi module to send check result and location coordinate to mobile phone. Mobile phone scans bar code to obtain basic information of watt-hour meter, transmits basic information of watt-hour meter, check result and location information to remote server through mobile data network, generates database of status of watt-hour meter and accomplishes calibration table according to this database. It can improve the working efficiency and solve the problems of false check, missing check, meter reading error, poor data timeliness and even data loss.
