Problems solved by technology

However, since the wireless communication channels are all in half-duplex mode, the channel using wireless communication is single. When multiple types of meters read meters at the same time, signal conflicts will occur, and the meters between adjacent users are relatively close. There will also be mutual interference and conflict of wireless signals, which will hinder the meter reading work

Abstract

The invention discloses a control method and system for multi-table centralized copying based on LoRa technology. The method includes: setting communication channel tables corresponding to various types of tables according to changes in spreading factors and bandwidths in specified frequency bands; The table type of the meter matches the corresponding first communication channel table for the meter; based on the table address of the meter, a channel is discrete from the first communication channel table as the communication when the meter is running channel. In the embodiment of the present invention, the shortcoming of a single wireless communication channel in the current multi-meter centralized reading system is overcome, signal conflicts are avoided when performing centralized meter reading on multiple types of meters, and the accuracy, speed and safety of meter reading work are ensured sex.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a control method and system for multi-meter centralized reading based on LoRa technology. Background technique [0002] In the current multi-meter centralized reading system, for the convenience of construction, wireless communication is often used to realize the unified centralized reading of electricity meters, water meters, gas meters and heat meters. However, since the wireless communication channels are all in half-duplex mode, the channel using wireless communication is single. When multiple types of meters read meters at the same time, signal conflicts will occur, and the meters between adjacent users are relatively close. There will also be mutual interference and conflict of wireless signals, which will hinder the meter reading work. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art. The pr...
