AI Technical Summary

Technical Problem

In multi-node communication systems, existing communication methods cannot guarantee stable and coordinated communication between multiple electronic devices of the same type, resulting in decreased bus communication efficiency and affecting the reliability and stability of system operation, especially in dynamically changing application scenarios where scalability is insufficient.

Method used

By entering a listening state after the electronic device is powered on, parsing bus messages, obtaining the device serial number and performing a backoff delay, broadcasting an identity declaration frame to form a set of device serial numbers, sorting them to determine candidate master devices and assigning addresses, establishing a unified time base, and realizing relay-style sequential message transmission, the bus resource contention is reduced.

Benefits of technology

It improves the stability and reliability of multi-node communication systems, reduces uncertainty in the initialization phase, and ensures the orderliness of the communication process and the reliability of system operation.

Abstract

The application belongs to the technical field of communication interaction, and relates to a scheduling method and device of a multi-node communication system and the multi-node communication system. Through power-on monitoring and mode decision, the electronic device perceives the network state and selects a communication path, reducing initialization uncertainty; through backoff delay and identity declaration based on the device serial number, device information collection is realized and a unified serial number set is formed, providing a basis for scheduling; through sequencing to determine a target master device and complete address allocation, each device forms an explicit role division and sequence relationship, thereby providing a deterministic execution basis; through establishing a unified time reference, the influence of timing deviation is reduced; based on the address allocation queue and the time reference, message sending is organized, the communication process is orderly, bus resource competition is reduced, and the stability and reliability of system communication are improved.
