Description

Technical field [0001] The invention discloses a user terminal access system and method, in particular to an energy efficiency intelligent management and broadband access system and method based on fiber to the home. Background technique [0002] With the continuous advancement of technology and society, the energy resources of the earth are declining, and people's demand for energy is increasing. The whole society has higher and higher requirements for energy saving and energy efficiency improvement of electricity users. In order to cope with energy saving and emission reduction and to create a harmonious electricity environment, people's electricity terminals are becoming more and more intelligent, and the central office and electricity users have further requirements for interaction and communication with electricity terminals. At present, the electric energy meter, which is one of the main metering terminals of electricity users, has gradually developed into an intelligent el...

AI Technical Summary

Problems solved by technology

At present, the electric energy meter realizes communication through RS485, PLC narrow-band power line carrier or wireless. The communication distance is short, the use range is limited or the interference is relatively large, and the communication cost is high, which makes the data acquisition reliability and data transmission of the electric energy meter real-time. At the same time, the security and reliability of information cannot meet the management objectives of smart grid for user management

Moreover, a big difficulty in broadband user access in the prior art is that it is very difficult to lay out or transform the communication lines in the user's home, so laying the data lines inside the home according to the conventional twisted pair will face cost and the test of usage habits
