Electric meter reading system and method

Abstract

The invention relates to an electric meter reading system and method. The system comprises an electric meter concentrator and electric meter measuring units. The electric meter concentrator comprisesat least one electric meter interface, each electric meter interface is used for being inserted by one electric meter measuring unit, the electric meter concentrator further comprises a first interface communication module, and the first interface communication module is in communication with the electric meter measuring units through the electric meter interfaces; the electric meter measuring units are inserted into the electric meter concentrator through the electric meter interfaces and include measuring modules used for recording power consumption data for users, the electric meter measuring units further include second interface communication modules, and the second interface communication modules are in communication with the electric meter concentrator through the electric meter interfaces. The electric meter measuring units of the system are directly inserted into the electric meter concentrator, and the situation is equivalent to the integration of the electric meter concentrator and electric meter measuring units as a whole part. Therefore, the communication between the electric meter measuring units and the electric meter concentrator is internal communication, interference can be reduced, and the communication reliability is improved.

Description

technical field [0001] The present invention relates to the field of electric meter reading, in particular to an electric meter reading system and a method for electric meter reading. Background technique [0002] With the development of society, smart grid has gradually become the focus of investment and development in our country. The construction of smart grid will promote the rapid development of smart communities and smart cities, and continuously improve people's quality of life. Among them, the household smart power consumption system can not only realize real-time control and remote control of smart home appliances such as air conditioners and water heaters, but also realize functions such as automatic meter reading and automatic transfer and payment through smart meters, making life more convenient; in addition, smart grids can Promote the transformation of the role of power users, so that they have dual attributes of electricity consumption and electricity sales, ...

Problems solved by technology

However, with the popularization of the system, its reliability and security problems have become increasingly prominent. These problems not only bring a lot of trouble to the on-site construction and maintenance personnel, but also have a negative impact on the service quality and network construction of the entire smart grid.

[0004] Stand-alone meters usually use PLC (power carrier) / GPRS (general packet radio service technology) and other long-distance communication methods to communicate with concentrators or master stations, which are limited by channel bandwidth or wireless signal interference, resulting in low communication reliability, making remote It is difficult to further improve the success rate of meter reading / timely rate of meter reading
