【摘要】：国家发改委和能源局在《关于促进智能电网发展的指导意见》中提到要将煤、电、油、气领域的信息资源进行共享,对水、气、电、热的统一集采集抄进行支持,建设数据集成平台以利于跨行业能源运行动态的监测,提倡能源与信息基础设施复用共享,这为推进水、电、气、热多表合一的数据采集和监测提供了较有利的政策支持。首先,本文阐述了四表集中采集的背景情况和国内各省市的发展布局情况,并分析了四表集中采集的意义和目的,并从经济效益和信息互通等方面可以了解到四表集中采集对于社会发展的深远意义。其次,本文所述设计是依照标准《DL/T698-2010电能信息采集与管理系统》和《Q/GDW-2013电力用户用电信息采集系统》关于采集部分的软硬件功能性能等要求来实现的。其硬件是基于NUVOTON公司的32位高性能NUC972微控制器芯片为平台开发的,利用MBUS和RS485采集电、水、气、热表的实时数据,利用软件对采集来的数据进行运算转化,存储到1Gb容量的NANDFLASH中,并通过4G通讯模块EC20把结果上送到系统主站以供分析处理。最后,通过在实验室搭建环境来进行国家电网和各省网公司相关要求项目的测试,利用其测试数据来分析验证该四表集中采集终端设计的可行性和稳定性,从而达到电、水、气、热表的一体化采集和能源与信息基础设施共享复用的目的。
[Abstract]:The National Development and Reform Commission and the Energy Administration, in their guidance on promoting the development of the smart grid, mentioned the need to share information resources in the fields of coal, electricity, oil and gas, and to support the unified collection and reading of water, gas, electricity, and heat. The construction of data integration platform is conducive to the dynamic monitoring of cross-industry energy operation and the promotion of reuse and sharing of energy and information infrastructure, which provides a more favorable policy support for the integration of water, electricity, gas and heat multi-meter data collection and monitoring. First of all, this paper describes the background of the four-table centralized collection and the development and layout of the provinces and cities in China, and analyzes the significance and purpose of the four-table centralized collection. From the aspects of economic benefit and information exchange, we can understand the profound significance of centralized collection of four tables for social development. Secondly, the design is realized in accordance with the requirements of the standard < DL/T698-2010 power information acquisition and management system] and the < Q/GDW-2013 power user power information acquisition system > about the software and hardware functions of the acquisition part. Its hardware is based on the 32-bit high-performance NUC972 microcontroller chip of NUVOTON Company. It uses MBUS and RS485 to collect real time data of electricity, water, gas and thermometer, and uses software to transform the collected data into real time data. It is stored in the NANDFLASH of 1Gb capacity and sent to the main station of the system through the 4G communication module EC20 for analysis and processing. Finally, by setting up an environment in the laboratory to test the relevant requirements of the State Grid and the provincial power grid companies, and using its test data to analyze and verify the feasibility and stability of the design of the four-table centralized collection terminal, so as to achieve electricity, water, The purpose of integrated acquisition of gas and thermometer and sharing and reuse of energy and information infrastructure.
