Intelligent remote transmission electric meter based on broadcast television white frequency spectrum

Abstract

The invention relates to the technical field of intelligent electric meters, and discloses an intelligent remote transmission electric meter based on a broadcast television white frequency spectrum. The electric meter comprises a cloud 'intelligent equipment online management platform' for counting and collecting the power consumption of users in each region; and a radio and television white frequency spectrum communication base station used for receiving and integrating the data of the user electricity meters in each region and sending the data to the cloud 'intelligent connection intelligentequipment online management platform. According to the intelligent remote transmission electric meter based on the broadcast television white frequency spectrum, the broadcast television white spectrum communication base station is arranged; in practical application, the radio and television white frequency spectrum intelligent electric meter can be directly installed in a basement. Collected data are directly sent to the radio and television white frequency spectrum communication base station through a radio and television white frequency spectrum communication chip, relaying can be conducted between the base stations, the data finally reach a machine room of a management department, 2G / 4G or telecommunication and mobile optical fibers are not needed in the process, and more expenses andconstruction cost are saved.

Description

technical field [0001] The invention relates to the technical field of smart meters, in particular to an intelligent remote transmission meter based on radio and television white spectrum. Background technique [0002] At present, pulse type or photoelectric sensors are installed on civil electricity meters. The sensor is essentially a pulse generation circuit unit based on magnetoelectric conversion technology or photoelectric conversion technology, which converts the metering signal generated by the meter into a digital signal, and finally converts the collected metering value. Use the RS-485 interface to upload to the communication host set at intervals (usually no more than 1 km), and the communication host uploads to the management background through the optical fiber link. [0003] Since each meter needs to be connected to the communication host through the RS-485 bus to upload data, and the farthest communication distance of the RS-485 bus cannot be greater than 1 km,...
