Abstract

The invention discloses a Space Wire bus communication system and monitoring equipment of the Space Wire bus communication system. The monitoring equipment comprises a monitoring board card, a first Space Wire port, a second Space Wire port, a computer and a storage module; the monitoring board card is used for transmitting interaction data of external master node equipment and slave node equipment between the first Space Wire port and the second Space Wire port, decoding the interaction data to generate a corresponding data packet and carrying out time marking; the computer is used for reading the data packet added with a time marker of the monitoring board card, analyzing the data packet according to a Space Wire communication protocol, and storing analyzed packet header information, data information and time information into the storage module. The monitoring equipment is used for carrying out the time marking and recording on the interaction data; when communication faults occur, time and bit of fault data can be found through playing back the stored data packet, so that reasons of faults are found and the faults are positioned.

Description

technical field [0001] The invention relates to the field of electronic measurement, in particular to a SpaceWire bus communication system and monitoring equipment thereof. Background technique [0002] SpaceWire bus is a high-speed, point-to-point, full-duplex serial bus network with a code rate of 2-400Mb / s. It uses two pairs of differential signals in each direction to realize data encoding and transmission. This bus is widely used in aerospace and aviation fields . [0003] The traditional SpaceWire port data transmission and recording method is that after the SpaceWire master node device and the SpaceWire slave node device start to work, the SpaceWire master node device sends the data to be sent to the router, which is addressed by the router, and then the router outputs the data To the SpaceWire slave node device, the SpaceWire slave node device stores the data together with the current time. Or the SpaceWire slave node device sends data to the router, and the router...
