AI Technical Summary

Technical Problem

In half-duplex wireless intercom using LoRa technology, the two communicating parties cannot send and receive simultaneously, leading to information conflicts and communication delays, which affect the timeliness and efficiency of communication.

Method used

By constructing a logical design that simultaneously listens, triggers wake-up, intelligently sends, and coordinates sending and receiving, the terminal node dynamically adjusts its receiving and listening parameters after detecting a trigger word, notifies the relay node to temporarily store downlink data, and intelligently matches the sending method to avoid data collisions and loss.

Benefits of technology

It significantly improves the timeliness of communication and channel utilization, provides a smooth and natural full-duplex intercom experience, and reduces unnecessary waiting and retransmission time.

Abstract

This invention relates to the field of wireless communication technology, and in particular to a full-duplex wireless intercom method and device based on LoRa technology. The method includes: simultaneously performing reception monitoring and voice monitoring; upon detecting a trigger word in the voice, changing the reception monitoring parameters and notifying a relay node to temporarily store data; upon receiving a temporary storage confirmation notification from the relay node, initiating voice reception; matching the received voice data with a corresponding transmission method and sending the voice data to the relay node according to the matched transmission method; after the voice data transmission is complete, notifying the relay node to perform downlink data transmission and initiating reception monitoring; upon receiving a downlink transmission confirmation notification from the relay node, stopping data transmission and changing the reception monitoring parameters; and receiving data forwarded by the relay node, converting and playing it. This invention achieves a near-full-duplex communication experience on LoRa, a low-power wide-area network technology, through a logical design of simultaneous monitoring-trigger wake-up-intelligent transmission-coordinated transmission and reception.
