Problems solved by technology

However, the traditional serial communication adopts the bus mode for transmission. With the verification mode, when a fault occurs, part of the bus will be paralyzed, part of the bus will lose packets, and part of the bus will be retransmitted by error. The fault is relatively hidden. All serial data acquisition equipment can be used to find Whether there is a problem with the equipment connected to the bus, when a problem occurs, the actual situation at the time of the fault cannot be reproduced intuitively

Abstract

The invention relates to a high-speed data collection and processing system and method for a multichannel serial bus and relates to the field of data processing technology. Through the high-speed datacollection and processing system and method, a scheme of high-speed serial communication collection, processing and storage based on a micro CPU plus an FPGA and multiple types of serial transceiversis proposed, and the demands of an electronic system for problem checking analysis and serial bus communication monitoring and storage after a data anomaly occurs during serial bus high-speed communication can be met.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a multi-channel serial bus high-speed data acquisition and processing system and method. Background technique [0002] Various types of bus communication are widely used in today's era, and in recent years, there has been more demand for communication buses in the fields of industry, aerospace, and automobiles, especially for the reliability and stability of the bus. However, the traditional serial communication adopts the bus mode for transmission, and uses the verification mode. When a fault occurs, part of the bus will be paralyzed, part of the bus will lose packets, and part of the bus will be retransmitted by error. The fault is relatively hidden. All serial data acquisition equipment can be used to find Whether there is a problem with the equipment connected to the bus, when a problem occurs, the actual situation at the time of the fault cannot be reproduced intuiti...
