AI Technical Summary

Technical Problem

Existing pulse diagnostic devices have low data transmission efficiency when communicating between devices via CAN bus, making it impossible to transmit pulse information in real time, and increasing hardware speed cannot meet the requirements.

Method used

The data information corresponding to different bits in the data stream is bound to the identity tags of multiple slave devices. The master sends the data stream to multiple slave devices through the CAN bus and establishes a communication connection by matching the identity tags.

Benefits of technology

This enables multiple slave devices to receive data streams simultaneously in non-broadcast mode, reducing data stream fragment transmission chaos and improving data transmission rate and utilization.

Abstract

The application discloses a communication protocol method based on CAN bus and used for improving communication efficiency, and belongs to the technical field of communication control. Different bit data information in a data stream is bound to identity tags of a plurality of slaves, and a host sends the data stream to the plurality of slaves through a CAN bus to simultaneously communicate with the plurality of slaves, so that different bit data in a group of data streams can be used by the plurality of slaves in a non-broadcast mode, which is beneficial to orderly receiving of the data stream, greatly reduces the phenomenon of chaotic sending of data stream fragments, and improves the transmission rate of the data stream and the utilization rate of the data stream.
