Abstract

The invention discloses a data transmission method based on LORA wireless communication and a relay. The data transmission method comprises the steps of after carrier wave data is received by virtue of a carrier wave receiving module, determining whether a set working channel of an LORA wireless communication module is in an idle state, if yes, converting the carrier wave data into wireless data, and sending the wireless data by virtue of the working channel. By arranging the LORA wireless communication module, an LORA technique can be used in the transmission process of the carrier wave data and has the characteristics of long transmission distance and wide transmission range, so that an islanding phenomenon can be effectively avoided, and the metering of a remote meter can be finished.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a data transmission method and a repeater based on LORA wireless communication. Background technique [0002] The power carrier has been developed to the present, and there are narrowband, orthogonal frequency division multiplexing (Orthogonal Frequency Division Multiplexing, OFDM) technology, broadband and so on according to different communication methods. However, no matter what kind of communication method is used, the limitation of communication distance cannot be avoided, and the phenomenon of isolated islands is prone to occur. Especially in the vast rural areas, many substations have complex power supply relationships, long power supply line distances, insufficient carrier communication distance, and limited communication capabilities, resulting in frequent occurrence of isolated islands, so it is difficult to read meters in isolated islands.
