Abstract

The invention provides a movable launch platform network topology structure in order to guarantee that a movable launch platform driving control system network is reliable and/or easy to maintain. A movable launch platform driving control system comprises a main upper computer node, a standby upper computer node, a main station main PLC node, a main station standby PLC node, a slave station main PLC node, a slave station standby PLC node, a plurality of frequency converter nodes and a plurality of absolute value encoder nodes, the network topology structure comprises a basic automation communication network structure and a process automation communication network structure which are connected in sequence, and the basic automation communication network structure and the process automation communication network structure share the slave station main PLC node and the slave station standby PLC node. Due to the network topology structure, the reliability and the maintainability of the movable launch platform driving control system are improved, and it can be guaranteed that the rocket transfer task is smoothly completed.

Description

technical field [0001] The invention belongs to the technical field of communication networks in the aerospace industry, and more specifically relates to a network topology structure of an active launching platform. Background technique [0002] The movable launch platform is an important part of the movable launch platform, which is responsible for completing the vertical transfer task of the launch vehicle between the technical workshop and the launch station smoothly and safely. Its communication network is an important part of the active launch platform, which connects various parts of the system and realizes data transmission between them. The performance of the communication network directly affects the performance of the entire automatic launch system, so whether the layout and design of the communication network is reasonable is very important. [0003] With the development of computer technology, network communication technology and automatic launch technology, fie...
