Integrated terminal and method for controlling an AMI system

Abstract

The present invention relates to an integrated terminal for a home network-based AMI system for a smart grid, the terminal comprising: an inter-suprasystem communication module connected between a suprasystem (10) of an AMI system and a plurality of household appliances (36) from among electricity consumers, via communication means, respectively, and performs the function of an interface for communication with the suprasystem (10); an inter-electronic device communication module performing the function of an interface for communication between a plurality of electronic devices; and display means for simultaneously displaying information received from the suprasystem by means of the inter-suprasystem communication module, and displaying information received from an electronic device by means of the inter-electronic device communication module.

Description

technical field [0001] The present invention relates to an integrated terminal for a home network-based Advanced Metering Infrastructure System (Advanced Metering Infrastructure System) and a control method thereof for smart grids, and in particular to a method for using an AMI for interlocking Advanced Metering Infrastructure (AMI) and ZigBee Smart Energy Specification (Smart Energy Specification), the wireless communication protocol for home networks, and Device Language Message Specification (Device Language Message Specification), a communication protocol for electronic energy meters, combined with the previous Energy Service Interface A device that provides various information on energy usage, such as energy consumption and cost information, as a single device with an In Home Display. Background technique [0002] Smart grid, as its name means smart grid, refers to a smart grid that uses information and communication technology on the existing grid and combines energy n...

Problems solved by technology

[0014] However, in the above-mentioned previous method, the communication between the smart meter that functions as a gateway and the energy service interface (ESI) 31, and the communication between the home energy display (IHD) 32 and the household appliances 33 are all realized through the energy service interface (ESI) 31, Therefore, the communication system is complicated, and the definition of linkage function and role is not clear

[0015] Especially, in the network structure of ZigBee smart grid solution (ZigBee SEP), home energy display (IHD) 32 can't check the detailed information of the home appliance 33 that is connected on the network, and energy service interface (ESI) 31 has to the home appliance 33 Therefore, only simple information such as power consumption information can be viewed

In addition, in fact, the regulations for the linkage between the Energy Service Interface (ESI) 31 of the ZigBee Smart Grid Solution (ZigBee SEP) and the host system are not clear

[0016] Moreover, in the ZigBee Smart Grid Solution (ZigBee SEP), there is no regulation for firmware upgrades, so the implementation of this function cannot guarantee compatibility with the standard, and remote firmware upgrades require high reliability, but ZigBee RF The characteristics and communication mechanism are difficult to meet this requirement, and there is such a problem

[0017] In such a conventional system, due to the limitation of ZigBee communication, the amount of communication is insufficient, and the reliability of communication is limited.

[0018] Moreover, recently, smart devices of some manufacturers of household appliances do not use ZigBee-based smart grid solutions (SEP), such as household appliances that communicate based on Wireless Fidelity (WiFi). Dealing with the problem
