Description

Technical field [0001] The present invention relates to the technical field of information network construction of an information transmission platform, and more specifically, the present invention is a multi-protocol gateway device of an information transmission 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 launch control network, the vehicle control network, the power supply and distribution network, and the chassis network. In order to realize the informatization control of the informatization launch platform, it is necessary to realize the interconnection and intercommunication between the four network segments. However, the communication protocol between different network segments may be different, and corresponding conversion devices must be set. The traditional method is to set up the gateway unit according to the spe...
