Detailed description of the invention
On star, system based on 1553B bus is as shown in Figure 1.It comprises bus control unit (BC), a remote terminal
(RT), far putting terminal, mass storage and multiplexer, its remote terminal is effective with RT function
Load.But not every payload is all with RT function, and this is accomplished by the function far putting terminal to complete RT.Far
Put terminal and provide 1553B service for payload, organize and gather the data of payload, be passed in bus.
The data needing storage on satellite in each terminal are stored in mass storage, and carry out Error Correction of Coding/decoding.
It is that the data meeting data format requirement are transferred the data multiplexing from various information source.Pass through mass storage
Complete satellite playback of data when by way of ground receiving wastewater facility.The above equipment is all by bus control unit (BC)
Manage, this shows that device category that BC manages is various and quantity is many (≤31).This just requires the life of BC
Make table as required, order is evenly distributed in bus, prevent managerial confusion and accident from producing (such as fault
Data) bus transfer is impacted.
Generally, on data/address bus, the data type of transmission is different, data different for type, its
Transmission cycle can identical also can be different, call large period transmitting the slowest cycle under normal circumstances, the week of fastest transmission
Phase is referred to as the minor cycle.Message on satellite is usually and earth station mutual, the data volume of message very greatly, and 1553B
