AI Technical Summary

Technical Problem

Existing technologies for internal robot communication suffer from several problems, including half-duplex mechanisms limiting bandwidth utilization, non-shared medium architecture increasing hardware complexity, long-distance communication protocol overhead being unsuitable for ultra-short-distance scenarios, lack of deterministic communication guarantees, and excessive load on the master node.

Method used

An ultra-short-range full-duplex shared medium network is adopted. Each slave node is assigned a dedicated communication window by periodically dividing the time slots. Combined with multiple response modes and guard band mechanisms, communication parameters are dynamically updated to achieve deterministic communication.

Benefits of technology

It improves the determinism and system efficiency of internal robot communication, reduces the processing load and hardware complexity of the master node, and adapts to the changing communication needs of multi-node scenarios.

Abstract

The invention relates to the technical field of communication, in particular to a deterministic communication method and related equipment for an ultra-short-distance shared medium network, and the method comprises the following steps: acquiring communication parameters of the ultra-short-distance full-duplex shared medium network, and sending a control message to each slave node by a master node through a downlink communication channel, indicating a response mode of each slave node in the uplink communication channel, wherein the response mode comprises at least one of an immediate response mode, an on-time punctuality response mode, a periodic response mode and a multi-period array command mode; the slave node sends a response message to the master node through an uplink communication channel in the corresponding exclusive communication window or the shared competition communication window according to the response mode and the communication parameter; in the communication process, the master node dynamically updates communication parameters according to a network state, and issues an updated communication bandwidth map to the slave nodes in an incremental mode; according to the invention, deterministic communication can be realized in the ultra-short-distance shared medium network, the communication real-time performance is improved, and the load of the main node is reduced.
