Description
Technical field
The invention belongs to computer technologies, are related to the system that two kinds of rate 1553B buses share a physical link communication
And its implementation.
Background technology
In high reliable communication field, with the increase that the requirement of communication bandwidth, communication section are counted, the originally 1553B of 1Mbps
Bus is difficult to meet the needs of development, it is therefore desirable to the 1553B buses of higher rate, but be compatible original 1553B physics chains
Road, can be constant in original bus by analyzing verification, and the traffic rate of high speed 1553B is 2Mbps -5Mbps,
The rate of risk minimum is 2Mbps.How on the same link, the communication for completing two kinds of rate 1553B bus terminations is this
Invention solves the problems, such as.
Invention content
The present invention proposes the system integration method that two kinds of rate 1553B buses share a physical link communication, can
In the case where ensureing that good compatibility, cost price are low, two kinds of rate 1553B bus termination products is supported to be connected to same physics
Chain road, two kinds of rate 1553B bus systems of realization integrate.
The present invention is technical solution：
The system that two kinds of rate 1553B buses share a physical link communication, including：
First bus control unit makes the data of the first rate occupy physical link and is transmitted；
Second bus control unit makes the data of second of rate occupy physical link and is transmitted；
Bus management host distributes corresponding two kinds of speed datas to the first bus control unit and the second bus control unit
Transmission time slice.
The side of data transmission is realized based on the system that two kinds of above-mentioned rate 1553B buses share a physical link communication
Method is：The first bus control unit of bus management host pair and the second bus control unit distribute the transmission of corresponding two kinds of speed datas
Timeslice, the first bus control unit and the second bus control unit are respectively in each remote of respective transmission time slice tissue respective rate
Journey terminal completes data transmission.
When having ephemeral data transformation task and present physical link is deposited during idle time, bus management host can also dispatch
One bus control unit or the second bus control unit complete data transfer task in idle timeslice.
The present invention has the following advantages：
A) support the 1553B buses of two kinds of rates that can share same physical link and be communicated；
B) have the characteristics that be easily achieved, versatility is good, extendibility is good；
C) have the characteristics that hardware cost is low.
Description of the drawings
Fig. 1 is that two kinds of rate 1553B buses of the present invention share the system structure diagram of same link；
Fig. 2 is the bus communication scheduling time piece of the same two kinds of rate bus control units of Host Administration of the present invention.
Specific implementation mode
The present invention enables it respectively by the respective time by the bus control unit (BC) of two kinds of rates of the same Host Administration
Piece provides that the respective message of timesharing tissue solves the collision problem of two kinds of rate communications, has reached and has realized two in same link
The integrated purpose of kind rate 1553B communications.
Below in conjunction with the accompanying drawings and specific example the present invention is described in further detail.
As shown in Figure 1, two kinds of rate 1553B buses share a physical link communication system, only there are one bus managements
The bus control unit (BC-1 is 1M velocity modules, the module that BC-i is iM rates) of two kinds of rates of host computer control of node, bus
Managing main frame arranges bus communication frame in advance according to application communication demand, and each prime frame is completely the same, stringent in each prime frame
The communication scheduling timeslice for dividing two kinds of rate buses, as Fig. 2 shows.There are two types of timeslices, T1 to be allocated to 1M rates in frame
1553B bus time pieces, Ti are the 1553B bus time pieces for being allocated to iM rates.
Sometime piece T1-l (1,2 ... j) in, host forbids BC-i to send instruction, and only enabled BC-1 modules transmission refers to
It enables, organizes the bus message of 1Mbps to complete transmission between BC-1, RT-1 of 1M, physical link is by 1M rate bus apparatus at this time
It is special；And sometime piece Ti-m (1,2 ... k) in, host forbids BC-1 to send instruction, and only enabled BC-i sends instruction, group
The bus message for knitting iMbps completes transmission between BC-i, RT-i of iM, physical link is special by iM rate bus apparatus at this time.
By above timesharing dispatching method, the purpose that same link realizes two kinds of rate 1553B communications is realized.And
The bus that this method can promote the use of such as three kinds, four kinds rates of a variety of rates shares the solution of same physical link.
