Description
Technical field
The invention belongs to space flight and aviation technical fields, and in particular to a kind of electronic equipment on satellite synthesization managing and control system can mention
For a kind of high and low power consumption of integrated level, reliable and stable, strong scalability, number of devices and redundancy remote measuring and controlling interface can be reduced
Electronic equipment on satellite synthesization managing and control system.
Background technique
With the development of large-scale manned space flight device, manned space flight device is in-orbit for a long time, will constantly expand new task
And new hardware, more harsh demand is proposed to the integrated level of satellite borne electronic system, scalability and synthesization ability.Traditional
Based on satellite borne electronic system is designed with association type, system is constructed by basic unit of each autonomous device, this system is once built
At, it is difficult to new function is added, system does not have lasting extension, upgrading, business growth ability, and module and interface are turned to customize
Main, many kinds of, interface rate is low, and information interface is complicated and unintelligible, and resource utilization is low, causes that volume is big, weight is high, function
The problems such as consumption is big, operability is poor, failsafe link is more, expensive, makes Practical Project model task, especially manned space flight task face
Lingao risk.Based on the urgent need of above practical engineering application, currently, having carried out space flight synthesization electronic system both at home and abroad
Research, but spininess, to moonlet and Nano satellite platform, fundamental design idea is with single board computer or monolithic embedded chip
Core, interface rate and chip performance are limited, it is difficult to which the functional parameter demand for meeting large-scale task does not have sustainable mostly
Extended capability does not have directive significance to large-scale manned space flight task, thus it is comprehensive to study extensive depth electronic equipment on satellite
The demand for changing managing and control system is very urgent, imperative.
External typical space flight synthesization electronic system, as Britain Surrey is small in " SNAP-1 " of transmitting in 2000
Satellite, using board computer system as core, business datum and control command are electronic system with other points by CAN bus
System interacts.The for another example whole star electronic system of Ou Hang innings of GIOVE-A, be divided into communication system, number guard system, Attitude and orbit control system,
Propulsion system, power-supply system and the big system of base band payload six.Whole star is by the number pipe computer pair based on 386 CPU of Intel
CAN bus network is managed, and Attitude and orbit control system, propulsion system, power-supply system and base band load are equipped with CAN bus node.
Two canonical systems carry out the interaction of all data using CAN bus, and interface backup means are single, hardly have propagation energy
Power, and without unified massive store management function, can integrated control ability it is limited, can not achieve multiple functions same
Electric load load, each system constitutes independent, dispersion, limited to the enabling capabilities of high-performance, extensive space mission.
Chinese Patent Application No. is 201410224895.7, Changchun Institute of Optics, Fine Mechanics and Physics, CAS
The patent " total management system for platform load integration satellite " of xuwei application proposes a kind of for platform load one
The total management system of body satellite, but the total management system is more directed to small satellite platform design, only passes through between unit double superfluous
Remaining CAN bus carries out data interaction, does not have business datum, the interface separating capacity of control instruction data, when CAN bus occurs
When failure, no additional interface carries out data transmitting, can not carry out efficient communication between unit, load cell is caused to fail, and furthermore should
The total management system no data memory management functions that patent application is related to, can not storage to data and readback carry out it is of overall importance
Management and control, data storage with readback, single particle effect detection with restore function need to rely on each module complete independently, integrate
It spends poor, causes intermediate link excessive, the problem of failsafe link increases, the in addition instruction control for realizing OC instruction of the patent application
Making sheet and instruction sending module are instructed using CAN bus transmission, and since CAN bus is preemptive type bus, communication blocking will occur
With delay, the operation delay such as remaining module switch electricity will be caused big and the problem of mistake occurs, influence task overall execution, and
Not mentioning multiple functions can load in identical platform, the synthesization design of no working-flow, to electric load utilization rate
It is low, thus actually use and be limited in large-scale space platform, engineer application is poor.
