Module) and BC controllers (BC controller modules) function.
After electric (energization) in protocol bridge, link detection module utilizes the link detecting work(for accessing optical module in FC networks
Can, timing constantly detects the state of FC links, and (all " link " refers both to the light in FC networks herein by link
It is fine) connection status it is lasting report protocol bridge state switching control module.
Protocol conversion function (protocol conversion module) is the function of protocol bridge script, is responsible for completing FC-AE-1553 data frames
With the mutual translation function of MIL-STD-1553B data words.FC data frames are converted into MIL-STD-1553B data words, sent

The Optimized Implementation Method of specific FC-AE-1553 protocol bridges is as follows：
Fig. 4 is the signal of the working-flow of the optimization method of FC-AE-1553 protocol bridges according to embodiments of the present invention
Figure.
The embodiment of the present invention is provided with counter (Watch Dog, house dog) first in protocol bridge, for record protocol
The linking status of bridge and FC networks, it is 10 to set Watch Dog initial values.
As shown in figure 4, the embodiment of the present invention detects FC Link States first after system starts, when FC links are normal
When, the value for setting Watch Dog is 10 and checks protocol bridge working condition, judges whether it is in protocol conversion state, if
Then wait and enter next detection clock (detection cycle), if the state of protocol bridge otherwise is switched into protocol conversion work shape
State, then wait into next detection clock (detection cycle)；, will when FC links are abnormal and Watch Dog value is more than 0
Watch Dog value subtracts 1, judges whether Watch Dog are 0 afterwards, if then whether being according to the working condition of protocol bridge
Protocol conversion state, protocol bridge is switched to BC controller states and waits into next detection clock (detection cycle) or waits again
Wait to enter next detection clock (detection cycle), if being otherwise directly entered next detection clock (detection cycle)；When FC chains
When road is abnormal and Watch Dog value is not more than 0, judge whether the working condition of protocol bridge is in protocol conversion state, if
It is that protocol bridge is switched into BC controller states waits into next detection clock (detection cycle), if otherwise directly entering again
Enter next detection clock (detection cycle).
The specific explanations of the workflow of the embodiment of the present invention are as follows：
1. timing detects current FC Link States, each (also known as detection cycle, also known as detection clock) time clock cycle
For 1 millisecond (1ms).
In the process of running, do not know when link failure can occur, it is therefore desirable to link is carried out at regular intervals
Detection, checks whether link breaks down.The strategy of timing detection is just examined at interval of certain time to the state of link
Survey.
Detection cycle is shorter, responds faster after link failure, and system of embodiment of the present invention minimum can support Millisecond
Detection, so the embodiment of the present invention selects 1ms as detection cycle.
2. if Link State is in connection status, renewal Watch Dog value is 10 (detection numbers), and detects association
(working condition of protocol bridge is by setting a marker bit to identify for the working condition of view bridge.When working state of system switches,
The marker bit is changed, detection working condition performs by checking the marker bit), if protocol bridge does not operate at protocol conversion
Under working condition, then stop BC controller modules, protocol bridge is switched under protocol conversion state.Then wait and enter next
Individual detection cycle.
3. if protocol bridge Link State failure, Watch Dog count value is checked, if greater than 0, by Watch
Dog, which is counted, subtracts 1.When counter is 0, protocol bridge working condition is switched to BC controller states.The embodiment of the present invention is even
Detect the state switching that protocol bridge is just carried out after link failure for continuous 10 times, prevent certain error detection from causing switching state by mistake.
The numerical value of counter is too small to cause link detecting mistake to cause switching state by mistake, and numerical value is too big then to be caused to switch after failure
Operation responded slow.
4. a pair Watch Dog values detect, judge whether Watch Dog values are 0, if fruit is not 0, into next
Detection cycle is waited；If current Watch Dog values are 0, protocol bridge working condition is checked, if in BC controllers
State, then wait and enter next detection cycle, if protocol bridge is in protocol conversion working condition, protocol bridge is worked shape
State is switched to BC controller working conditions, waits and enters next detection cycle (descending 1ms).
Protocol bridge working method (state) switch instances are as follows：
A. under protocol bridge working condition, and if only if continuous 10 clock cycle, after all detecting that link breaks down,
Just the working condition of protocol bridge can be switched to BC controller states.
It is the optimal selection that system of the embodiment of the present invention passes through many experiments using 10 clock cycle (detection number),
It may cause false judgment because error tolerance is too small less than 10, time loss can be caused to become big more than 10.
Other systems environment can be done according to the minimum time precision of switching time and system after the failures of system requirements
Go out adjustment, meet formula " switching time after detection cycle * detection number=failures ".Selected parameter (1ms* herein
10=10ms), it is to be selected after being considered based on system precise time and failure recovery time.
B. under BC controller states, after any one detection cycle detects link failure recovery, immediately by protocol bridge
Working condition is switched to protocol bridge transition status.
5. after system starts, it will be run always according to working-flow, when system jam or disconnected
Terminate after electricity.
The optimization method of FC-AE-1553 protocol bridges according to embodiments of the present invention can be seen that because using according to agreement
The linking status of bridge and FC networks (optical-fibre channel transmission network), keeps or the working condition of handoff protocol bridge is protocol conversion shape
The technological means of state or bus control unit state, so overcome when the optical fiber that protocol bridge is connected to FC networks breaks down,
In whole MIL-STD-1553B buses the equipment of all mountings can out of control technical problem, and then in link generation
After failure, start BC controller modules (bus control unit module) in time, prevent the total built-in units of MIL-STD-1553B to be in
The technique effect of state of paralysis.And by setting counter in protocol bridge, with counting mode come record protocol bridge and FC nets
The linking status of network, so as to after a period of time for being broken down in link, start BC controller modules, preventing can not be fault-tolerant
Caused false judgment.Can also be after link failure recovery, effectively the working condition of handoff protocol bridge is protocol data
Transition status (protocol conversion state), the control of whole total built-in unit is transferred into NC (Net Controller, network control
Device, the transmitting-receiving in whole FC networks between all data are all network controlled device control), realize dynamic control right transfer.Moreover,
By the linking status of timing detection protocol bridge and FC networks, so as to rapidly find linkage fault and fault recovery, and
When handoff protocol bridge working condition.

The value of the counter is arranged to detect number；When protocol bridge and linking for optical-fibre channel transmission network break down, and institute
When stating the value of counter more than zero, the value of the counter is subtracted one.
In addition, the value that switching control module 203 can be additionally used in the counter is detection number, and the work of the protocol bridge
When to make state be protocol conversion state, the working condition of the protocol bridge is kept；When the counter value for detection number, and
When the working condition of the protocol bridge is bus control unit state, the working condition of the protocol bridge is switched into protocol conversion shape
State；When the value of the counter is zero, and the working condition of the protocol bridge is bus control unit state, the agreement is kept
The working condition of bridge；When the value of the counter is zero, and the working condition of the protocol bridge is protocol conversion state, by institute
The working condition for stating protocol bridge switches to bus control unit state.
In addition, the detection cycle in the optimization device 200 of the FC-AE-1553 protocol bridges of the embodiment of the present invention is according to being
What the minimum time precision of system was set, detection number be after the failure according to system requirements switching time set so that
Switching time=detection cycle * detection numbers after failure.
From the above, it can be seen that because using linking according to protocol bridge and FC networks (optical-fibre channel transmission network)
The working condition of state, holding or handoff protocol bridge is the technological means of protocol conversion state or bus control unit state, so
Overcome when the optical fiber that protocol bridge is connected to FC networks breaks down, all mountings in whole MIL-STD-1553B buses
