Low Voltage Remote Concentrated Ammeter Reading System

Low-pressure centralized remote meter reading system is one system that main station Channel copies concentrated reading date (power line carrier, utility cable, wireless communications network, etc)by allocating under the various types of variable electric metering equipment table or the electric energy value of the information recorded. The system is mainly collected from users of electric power energy forms of information collection terminals, concentrator, master station, Communication Channel and other components, data access can be transmitted to remote master computer, and adopt corresponding interface with the marketing system to achieve seamless connectivity, real-time transmission of data, providing analysis to put forward underlying data sources for a comprehensive analysis of energy consumption. Combination with China's power market with the status and demands of the meter-reading system, the following aspects were studied andanalyzed in this paper:First, Based on analysis of several aspects of needs of users, the power industry market, laws and regulations, and power management and development, it comes out that concentrated meter-reading system will play an irreplaceable role in the future application of the electricity field with very good prospects.Secondly, by the compare of different forms of automatic meter reading systems, including the technical and economic comparison, their respective advantages and disadvantages are summed up in this paper. According to different environment, need of users, it is necessary to adopt different combinations of system as to achieve the purposes of conservation of resources and improving efficiency. Third, the paper analyzes the characteristics of the power industry and status of technology development; In particular, in the condition of general upgrading and transformation of current power industry marketing system, requirements of meter reading system must be also in the simultaneous access. In the design of main points, focus on the functionality delivered optimization, and by sub -modular design ideas, deep research and study has been carried on the structure of system and design of the database and so on, so that the design has high reliability and practical value.With the continuous improvement of district intelligence and change of people's concept, technology applications of low-pressure centralized meter reading not only solves the difficulty of meter reading department, charging that favors a series of issues such as meter reading, but also it can make timely access to electricity, Energy Demand and load curve information of the low-pressure time-sharing users, understand state of lines, rationalize of the distribution of electricity, and reducing line losses. Therefore, research and development of low-pressure centralized meter reading, not only provided a favorable technical means for users of low pressure, but also bring huge economic benefits for the power industry with a very strong sense of practicality.
