Moonlet multi-bus multi-passage communication monitoring device and monitoring method thereof

Abstract

The invention provides a moonlet multi-bus multi-passage communication monitoring device and a monitoring method thereof, which relate to a communication monitoring device and a monitoring method thereof. The invention is provided by aiming at solving the problems that the monitoring device can only monitor the bus modes of the same type, in addition, the monitored passages are few. The data signal output end and the data signal input end of an interface module of each path of CAN bus respectively correspond to the signal input end and the signal output end of one path of CAN bus of a first monitoring control module, the interface module of each path of CAN bus respectively receives a path of CAN bus signals from an external bus, the data signal output end and the data signal input end of an interface module of each path of RS-422 bus respectively correspond to the signal input end and the signal output end of one path of RS-422 bus of a second monitoring control module, and the interface module of each path of RS-422 bus respectively receives one path of RS-422 bus signals. The invention can monitor two kinds of buses, can simultaneously monitor multi-passage data, and can be widely applied to various occasions needing simultaneous monitoring of multi-passage data.

Description

technical field The invention relates to a communication monitoring device and a monitoring method thereof, in particular to a small satellite communication monitoring device and a monitoring method thereof. Background technique In the small satellite communication system, various sensors, servo mechanisms and the central computer need to transmit data and instructions through a bus connection, and the accuracy of the transmitted data is crucial. This requires the detection system to monitor and analyze the data coming and going on the bus in real time to determine whether each device and each channel is in a normal working state. Bus communication monitoring means that the measurement and control system takes the communication bus as the test object, and judges the status of the data source and channel by monitoring the data transmitted on the bus. Since a variety of bus control or data exchange methods are used on the small satellite, and there are many channels and the c...
