At present, Multifunctional Smart Meter can realize remote meter reading, remote payment and remote load control function. At the same time, the electric meter also has the function of preventing the theft of electricity, monitoring the power network events, recording the load curve and freezing. However, it is still unable to meet the frequent needs of information interaction in the Internet era, and can not meet the diversified needs of users after the electricity market.

There are three main areas where smart meters still need to be improved.

1. The existing smart meter has the function of time-sharing measurement , but the electric energy measurement in electric meter, unable to respond to multiple price model of future fast, when the policy adjustment, need to modify parameters of electric energy meter can be switched to the new pricing policy, operation time consuming.

2. The existing smart meter, legal metering and illegal metering is not separate, can not meet the needs of the upgrade of the power meter. When users need to change, they can only change the energy meter, which brings great waste of resources. The future energy meter needs to have the function of legal and non legal separation, and it can be upgraded for non statutory functions.

3. The existing smart meter local communication interface only RS485 and near infrared two modes of communication.

The future social development needs of large data acquisition, RS485 and NIR are unable to meet the requirements of communication efficiency for a long time a large amount of data, so the future of the electric energy meter in the local communication will be more flexible, need to have a variety of means of communication, such as Bluetooth, WiFi, etc.. In addition, with the development of communication technology, the remote communication interface of power meter will be greatly enriched. Broadband carrier, NB-Iot and so on will also be widely used.
