Embodiment 1

[0037] The management node is a ground-based measurement and control station, and the common nodes are several satellites. The orbit information of all satellites, the topology information of the entire TT&C communication network including the ground-based TT&C station and all satellites, and the task information that each satellite should perform (ie, information 1) have all been stored in the ground-based TT&C station. After calculation, the ground-based TT&C station sends to each satellite the tasks it should perform and which satellites it should connect with to form a specific topology (information 2) when each satellite passes over the top. All satellites perform this mission according to the mission information received, until they receive new mission information (namely information 4) from the ground-based measurement and control station when they pass over the top.

Embodiment 2

[0039] The management node is a ground-based measurement and control station, and the common nodes are several satellites. The orbit information of all satellites, the topology information of the entire measurement and control communication network including itself and all satellites, and the task information that each satellite should perform (ie, information 1) have all been stored in the ground-based measurement and control station. After calculation, the ground-based TT&C station sends to each satellite the tasks it should perform and which satellites it should connect with to form a specific topology (information 2) when each satellite passes over the top. All satellites perform tasks according to the received task information. After the task is completed or the task fails, it will send task completion information or task error information (ie, information 3) to the ground-based measurement and control station when it is over the top.

Embodiment 3

[0041] The management node is a ground-based measurement and control station, and the common nodes are several satellites. The orbit information of all satellites, the topology information of the entire TT&C communication network including the ground-based TT&C station and all satellites, and the task information that each satellite should perform (ie, information 1) have all been stored in the ground-based TT&C station. After calculation, the ground-based measurement and control station will forward the tasks of all satellites and which satellites should be connected to form a specific topology (ie information 2) to other satellites through the satellite when a certain satellite is over the top. All satellites execute this mission according to the received mission information until they receive new mission information (ie, information 4) from the ground-based TT&C station. The transmission of information 4 is also forwarded to all satellites through a certain overhead satelli...

Abstract

The invention discloses an intelligent measurement and control communication network system, and aims to provide a network system capable of increasing the network operating efficiency and operating capability and satisfying diversified services. The intelligent measurement and control communication network system disclosed by the invention is realized through the technical scheme as follows: an intelligent measurement and control communication network is at least composed of two types of nodes including management nodes and normal nodes; the whole intelligent measurement and control communication network is logically divided into a control plane and a service plane; the control plane and the service plane respectively adopt different networking modes responsible for its responsibility; the control plane selects a shortest-path routing strategy, so that the management nodes on the control plane can be communicated with all normal nodes; the service plane is divided into multiple task sub-networks according to tasks executed by the nodes; the various task sub-networks can select different routing strategies according to respective task requirements; according to application and scene requirements of a task, with the help of externally variable parameters, the control plane performs intelligent learning by utilizing a machine, generates a new mathematical model in real time, andsends a new task instruction to the service plane; a foundation measurement and control station is communicated with the management nodes through a satellite-to-earth link; and measurement and controlcommunication of the normal nodes is indirectly carried out through the management nodes.
