Spaceflight ground measurement and control station all-digital resource pool architecture

Abstract

The invention relates to a spaceflight ground measurement and control station all-digital resource pool architecture, which comprises front-end equipment, terminal equipment and public equipment, andis characterized in that the front-end equipment and the terminal equipment carry out resource recombination through a digital exchange network and are recombined into a measurement and control systemwith specific measurement and control capability under the cooperation of the public equipment. The full-digital resource pool architecture of the spaceflight ground measurement and control station is based on the designed resource pool architecture with front-end equipment solidification combination, terminal equipment flexible recombination and public equipment unified configuration, and corresponding digital implementation technologies such as radio frequency direct acquisition, network reliable transmission, time delay real-time correction and full-link hot backup are adopted. It is guaranteed that different measurement and control devices in the same station address stably and reliably complete tasks, recombination is flexibly and efficiently achieved, the construction mode that a traditional large measurement and control station guarantees tasks through quantity is changed, and a foundation is laid for intensive, efficient and on-demand configured construction routes in the future.

Description

Technical field[0001]The invention relates to the technical field of radio measurement and control, in particular to an aerospace ground measurement and control station all-digital resource pool architecture.Background technique[0002]The main task of the spacecraft ground measurement and control station is to complete the measurement of the spacecraft's distance, speed and angle, as well as remote data transmission and remote measurement data reception, and complete the relevant business data interaction with the center according to the agreed interface requirements. A single set of measurement and control equipment in the station is generally composed of sub-systems such as antenna feeding, transmitting, receiving, baseband, monitoring, time-frequency, testing and calibration, and data interaction. According to this architecture, the measurement and control station is often organized and implemented in a "chimney-style" construction mode. ,Such asfigure 1 As shown, each set of equi...

Problems solved by technology

However, this design scheme makes the IF switch matrix a single-point device for the entire site, and in order to realize full signal exchange between all channel devices and baseband devices, the matrix scale is very large and the design of the internal switching network is complicated, which directly affects the entire site. Mission Reliability of Measurement and Control Stations

In addition, with the continuous addition of new equipment, the number of interfaces of the IF switch matrix will become an important restrictive factor, and it may not even cause the entire system to shut down and cooperate, which is unacceptable for measurement and control tasks

At the same time, based on the reorganization architecture of analog signals, the loss and distortion in the long-distance transmission of radio frequency signals, and the isolation and interference problems in the recombination of intermediate frequency signals have also become unavoidable technical shortcomings of the architecture.
