Power broadband carrier communication meter reading system

Abstract

The invention discloses a power broadband carrier communication meter reading system. The power broadband carrier communication meter reading system comprises a master station, a concentrator, a site meter, a concentrator carrier communication module and a meter communication module, wherein the concentrator is in communication connection with the master station through a GPRS communication network, the concentrator is in communication connection with the site meter by virtue of a power line, the concentrator is inserted into the concentrator carrier communication module, the meter communication module is inserted into the site meter, and the concentrator carrier communication module is in communication connection with the meter communication module by virtue of a power line. The power broadband carrier communication meter reading system disclosed by the invention can realize long-distance networking communication transmission, networking mechanism timeliness is strong, and networking time is short; meanwhile, the reliability of data transmission between the concentrator and the master station is improved through GPRS remote communication, and meter reading success rate of an acquisition system is guaranteed; and a communication module for the concentrator and the site meter adopts a plug-and-play communication module, and interchange and reuse of the module can be facilitated, so that repeated work of system design is avoided.

Description

technical field [0001] The invention relates to the technical field of power line carrier communication, in particular to a power broadband carrier communication meter reading system. Background technique [0002] The power user centralized reading system is a power information collection, processing and real-time monitoring system. In this system, the concentrator is responsible for collecting the data of each collection terminal or electric energy meter, processing and storing it, and exchanging data with the master station or collector at the same time. The concentrator can communicate with the master station, receive commands from the master station, and transmit data to the master station, and the concentrator should be able to receive and forward commands from the master station, and collect and control data from the energy meter. In recent years, with the advancement of the State Grid Corporation of China's smart grid construction, the power consumption information c...
