Description

technical field

[0001] The invention relates to the technical field of information network construction of an information launch platform, and more specifically, the invention is a multi-protocol gateway device of an information launch platform. Background technique

[0002] In the information control system of the information launch platform, the network architecture is divided into four network segments, including the measurement and control network segment, the vehicle control network segment, the power supply and distribution network segment, and the chassis network segment. In order to realize the informatization control of the informatization launch platform, it is necessary to realize the interconnection and intercommunication among the four network segments. However, the communication protocols between different network segments may be different, and corresponding conversion devices must be installed. The traditional method is to set the gateway unit accordingly acco...
