Abstract

The invention discloses a remote electric quantity automatic acquisition system. The system comprises an intelligent electric energy meter, a data collector, a power line modem 2, a low-voltage power net, a power line modem 1, a concentrator, a modem 2, a data communication network, a modem 1 and a remote server meter reading center, the data collector is embedded in the intelligent electric energy meter and is used for converting the collected power consumption data into data in a form suitable for power line carrier transmission by the power line modem 2 and the data is output and transmitted by the low-voltage power net. The data subjected to carrier transmission of the low-voltage power net is converted into data in the other data format by the power line modem 1. The data in the other data format is transmitted into the concentrator. The concentrator automatically carries out system self-inspection, and records an event and gives an alarm when equipment abnormity is found. The system has the advantages of good reliability, data accuracy, high adaptability, complete functions, small module volume and low power consumption.

Description

technical field [0001] The invention relates to a power collection system, in particular to a remote automatic power collection system applied in the field of power supply and distribution. Background technique [0002] With the rapid development of electric power construction, the scale of power grid continues to expand. In many cases, the construction and equipment maintenance of power grids are becoming more and more frequent. The transmission line as the link of power transmission has the characteristics of long distance, large dispersion, and difficulty in inspection and maintenance. The following Tricon product "online monitoring system for transmission line status" can monitor the status of transmission lines very well. [0003] Automatic meter reading system refers to a new technology that uses communication and computer network technologies to automatically read and process meter data. The development of automatic meter reading technology is the need to improve th...
