Abstract

The invention discloses a distribution line based remote wireless communication transmission device and method for electric current information. The device comprises a case and a solar photovoltaic cell panel arranged on the case, wherein a charging circuit, a storage cell, an isolated DC / DC module, a microcontroller, a GPRS (general packet radio service) wireless communication module and a Zigbee wireless communication module are arranged in the case, the output end of the solar photovoltaic cell panel is electrically connected with the input end of the charging circuit, the output end of the charging circuit is electrically connected with the input end of the storage cell, the electric energy output end of the storage cell is electrically connected with the input end of the isolated DC / DC module, and the output end of the isolated DC / DC module is electrically connected with the power input ends of the microcontroller, the GPRS wireless communication module and the Zigbee wireless communication module. According to the invention, the measurement precision of an electric current acquisition unit of a distribution network can be improved, besides, the combination of the solar photovoltaic cell panel and the storage cell is adopted as a main power supply of the remote wireless communication transmission device, an external power supply is not required, and energy-saving and environment-friendly effects are realized.

Description

technical field [0001] The invention relates to a current detection and transmission device, in particular to a remote wireless communication transmission device and method for current information based on distribution network lines. Background technique [0002] At present, the measurement of the line current of the distribution network can usually only be measured at the outgoing end of the line, while the current measurement in the middle of the line, its end, and each branch of the line is difficult due to the lack of power supply and the installation of measuring equipment on the line. Various factors such as the lack of remote wireless communication equipment that can transmit the current information of the line to the background software of the substation make it difficult to perform these measurements. So far, no current measurement in the distribution network line and its various branch lines has been found. device. Due to the lack of current detection devices suit...
