Meter reading system and meter reading method

Abstract

The invention relates to an electric meter reading system and an electric meter reading method. The system includes: an electric meter concentrator, including at least one electric meter interface, each electric meter interface is used for plugging with an electric meter measurement unit, and the electric meter concentrator also includes The first interface communication module, the first interface communication module communicates with each meter metering unit through the meter interface; the meter metering unit is plugged into the meter concentrator through the meter interface, and the meter meter unit includes a power consumption data for the user. The recorded metering module, the meter meter unit also includes a second interface communication module, and the second interface communication module communicates with the meter concentrator through the meter interface. The meter metering unit of the present invention is directly plugged on the meter concentrator, which is equivalent to the integration of the meter concentrator and the meter meter unit as a whole, so the communication between the meter meter unit and the meter concentrator is internal communication, which can reduce interference and improve communication reliability.

Description

technical field [0001] The present invention relates to the field of electric meter reading, in particular to an electric meter reading system, and also to an electric meter reading method. Background technique [0002] With the development of society, smart grid has gradually become the focus of investment and development in my 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 electricity consumption system can not only realize real-time control and remote control of smart 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 electricity users, so that they have the dual attributes of electricity consumption and ele...

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
