AI Technical Summary

Technical Problem

Existing technologies make it difficult to achieve time synchronization between master and slave stations, which hinders the promotion and application of industrial real-time communication technology in different field application environments.

Method used

Each slave station is identified through device scanning and station number allocation frames. An enable slave station delay measurement frame is sent to the slave station to obtain the transmission delay time. A synchronization frame is sent to the slave station based on the communication cycle to enable the slave station to generate a synchronization signal to synchronize with the master station.

Benefits of technology

It achieves time synchronization between the master station and the slave station, reduces the development difficulty of real-time networks, eliminates the need to design complex protocols and high-cost chips, and meets the requirements of industrial real-time communication.

Abstract

The application discloses a communication method, module, device, terminal equipment and medium of a master station and a slave station, determines each slave station through device scanning and a station number allocation frame; sends an enable slave station measurement delay frame to each slave station, so that each slave station respectively responds to the enable slave station measurement delay frame to obtain corresponding transmission delay time; acquires a communication period, and periodically sends a synchronization frame to each slave station based on the communication period, so that each slave station generates a slave station synchronization signal according to the synchronization frame and the corresponding transmission delay time, and communicates data transmission with the master station according to the slave station synchronization signal. By determining the corresponding transmission delay time of each slave station, and generating the slave station synchronization signal based on the corresponding transmission delay time, the time when each slave station generates the synchronization signal is consistent with the time when the master station generates the synchronization signal, synchronization control is realized, the effect of real-time communication can be achieved without designing a complex protocol and a high-cost chip, and therefore the development difficulty of a real-time network is reduced.
