Communication method, apparatus and system for smart meter

Abstract

According to the embodiments of the invention, a communication method, apparatus and system for smart meter are provided. In the smart meter, the domain name of a parameter server is pre-stored. The method comprises the following steps. The smart meter obtains the IP address of the parameter server corresponding to the domain name from a domain name system (DNS) server. The smart meter, based on the IP address of the parameter server, obtains the IP address and the port number of a data acquiring platform (DCP) from the parameter server. The smart meter, based on the IP address and the port number of the DCP communicates with the DCP. According to the embodiments of the invention, based on the pre-stored domain name and the acquisition of the IP address of a parameter server from an DNS, it is possible to obtain the IP address and the port number of the data acquiring platform of the parameter server and to realize the communication with the data acquiring platform. Therefore, the smart meter can be automatically configured without the configuration by people on the site. As a result, when large scale deployment of smart meters takes place, the configuring workload can be reduced obviously.

Description

technical field [0001] The present invention relates to the field of communication, and more particularly, to a method, device and system for smart meter communication. Background technique [0002] At present, there are multiple communication methods on the meter side in the electric meter reading system, which can be divided into wired methods and wireless methods. In densely populated urban areas, wired methods with relatively short transmission distances such as Programmable Logic Controller (PLC) and Recommended Standard (RS) 485 are mainly used for unified wiring and cost savings. In some remote mountainous areas, or in large enterprises, large factories and other places, the installation of electric meters is relatively scattered, and the cost of using wired methods will be relatively high. General Packet Radio Service (GPRS) electric meters can be used to communicate wirelessly. . [0003] Usually, a GPRS power meter reading system consists of a data collection pla...

Problems solved by technology

However, this method also requires manual on-site operation, and requires the use of a portable computer to send messages, which requires relatively high technical ability of the operator

Similarly, when the number of GPRS meters that need to be configured is large, the operation is time-consuming and the workload is heavy
