Abstract

A kind of spacecraft bus router of Component- Based Development module, is related to a kind of spacecraft bus router.Existing spacecraft is solved because multibus and the form of depositing bring difficult communication between bus, the problem of causing communication efficiency low.The bus router includes bus registration management module and intermediate member data exchange module, and bus router is communicated with N number of component respectively by multiple bus, N is positive integer, bus registration management module, for managing spacecraft bus registration, bus component subject is extracted, according to component communication mapping table between bus component subject management bus, registers intermediate member；Intermediate member data exchange module includes multiple intermediate members, for realizing the data exchange between intermediate member.It is used primarily in the information communication in spacecraft field.

Description

A kind of spacecraft bus router of Component- Based Development module

Technical field

The present invention relates to a kind of spacecraft bus router.

Background technology

At present, to improve versatility, spacecraft tension management uses Component Technology, connected between component by software bus Connect, preferably to play component generalization advantage, spacecraft employs a plurality of software bus.Spacecraft is because of multibus and deposits form The problem of bringing difficult communication between bus.

The content of the invention

The present invention is to solve existing spacecraft because multibus and the form of depositing bring difficult communication between bus, cause to communicate The problem of efficiency is low.The invention provides a kind of spacecraft bus router of Component- Based Development module.

A kind of spacecraft bus router of Component- Based Development module, the bus router include bus registration management mould Block and intermediate member data exchange module, and bus router is communicated with N number of component respectively by multiple bus, N is just Integer,

Bus registration management module, for managing spacecraft bus registration, bus component subject is extracted, according to total line components Component communication mapping table, registers intermediate member between Subject Manager bus；

Intermediate member data exchange module includes multiple intermediate members, for realizing the data exchange between intermediate member.

Described bus registration management module, for managing spacecraft bus registration, bus component subject is extracted, according to total Component communicates mapping table between line components Subject Manager bus, register the detailed process of intermediate member as：

Spacecraft software bus is total to this bus of bus registration management Module registers, bus router extraction spacecraft software Line components address,

According to spacecraft software bus component address, bus router seeks bus component subject all over, when a component need to be with During other total line components communications, communication means are inserted into mapping table, register intermediate member.

The intermediate member data exchange module includes multiple intermediate members, for realizing the data exchange between intermediate member Detailed process be：

Component communication time slot between wait bus, bus router component mapping table is searched according to component subject,

If without corresponding bus router component mapping list item, terminate this communication；

Otherwise, according to component subject, the component that need to be communicated is sent in the bus where the component that need to be communicated to this, bus Data exchange is carried out with the intermediate member corresponding to the component that need to be communicated and another intermediate member in router component mapping table, and Another intermediate member is sent data in other buses beyond the bus needed where communication means,

With needing communication means corresponding by communication means number is read from the bus for receiving another intermediate member and sending data According to the data exchange between completion intermediate member.

The beneficial effect that the present invention is brought is that the invention provides a kind of spacecraft bus of Component- Based Development module route Device, the communication between bus is preferably realized, communication efficiency is improved more than 50%.

Brief description of the drawings

Fig. 1 is a kind of principle schematic of the spacecraft bus router of Component- Based Development module of the present invention；

Fig. 2 is the principle schematic that intermediate member 1 and intermediate member 2 carry out data exchange；

Fig. 3 is the flow chart that intermediate member 1 and intermediate member 2 carry out data exchange.

Embodiment

Embodiment one：Illustrate present embodiment, a kind of Component- Based Development mould described in present embodiment referring to Fig. 1 The spacecraft bus router of block, the bus router include bus registration management module and intermediate member data exchange mould Block, and bus router is communicated with N number of component respectively by multiple bus, N is positive integer,

Embodiment two：The boat of present embodiment and a kind of Component- Based Development module described in embodiment one The difference of its device bus router is that described bus registration management module, for managing spacecraft bus registration, extraction is total Line components theme, component between bus is managed according to bus component subject and communicated mapping table, register the detailed process of intermediate member as：

Embodiment three：The boat of present embodiment and a kind of Component- Based Development module described in embodiment one The difference of its device bus router is that the intermediate member data exchange module includes multiple intermediate members, in realization Between the detailed process of data exchange between component be：

With needing communication means corresponding by communication means number is read from the bus for receiving another intermediate member and sending data According to the data exchange between completion intermediate member.In present embodiment, in being illustrated by taking intermediate member 1 and intermediate member 2 as an example Between data exchange between component principle, referring specifically to Fig. 2；

Component communication time slot between wait bus, bus router component mapping table is searched according to component subject；

If without correspondence mappings list item, terminate this communication；

Otherwise, sent data to according to component subject, component 1 in bus 1, intermediate member 1 reads data from bus 1；

Bus router realizes 1,2 data exchange of intermediate member；

Intermediate member 2 is sent data in bus 2, and counterpart member 2 reads data from bus 2, this sign off, etc. Treat that next communication time slot arrives.

Intermediate member 1 and intermediate member 2 carry out the workflow diagram of data exchange referring to Fig. 3.
