Problems solved by technology

[0002] At present, household electricity is mainly measured by ordinary electric energy meters, and the power supply bureau charges according to the data of electric energy meters. The data collection of electric energy meters is mainly through the bus. The bus is connected to a switchboard, and then the switchboard uniformly transmits the data to the center of the power grid power supply bureau to realize centralized meter reading. This method makes the formation of the smart meter network more complicated, and each smart meter must be wired. Switchboards arranged in buildings and other places, so special wiring for smart meters is required
In addition, the functions of the existing smart meters are relatively simple, basically only to realize the measurement of electricity, and send the data to the server of the power supply bureau in one direction, which is used to collect the basis of electricity charges, and has no other functions. This is a closed system with no external interface. , Ordinary household users cannot obtain electricity consumption information locally from the energy meter, and cannot expand and realize other new functions
[0003] At present, the electric energy meter does not have the function of electricity consumption monitoring and abnormal electricity consumption alarm. The power supply bureau usually operates and maintains the main line. If the power supply of a single user is abnormal, the electric energy meter will not automatically cut off the power supply, and the power supply bureau will not be able to obtain it automatically at the first time. It relies on users to call for feedback, and then go to the site to investigate and solve the problem. This method not only has low processing efficiency, but also usually leads to long periods of power outages in households. At the same time, there are hidden dangers in the safety of household electricity consumption, which greatly affects the level of power supply services.
