As shown in Figure 1, it is divided into ARINC661 figure configuration file, resource pool layer, operation layer and client layer from software frame,
ARINC661 figure configuration file completes the configuration of graphical control primary attribute and display graphic plotting, resource pool layer complete figure control
The attribute initialization of part and Graph Control interface realize that the form of software library is realized.Operation layer includes the display of User Exploitation
Logic, failure detection algorithm library, race condition algorithms library and detection configuration file.Client layer is the set of one group of display unit,
It is based primarily upon the display that ARINC661 specification completes graphical control.
1) ARINC661 control resource pool data are synchronous:
It standardizes and defines according to ARINC661, avionics display & control system is divided into display system and logic control two parts, display system
System carries out modularized design with logic control system respectively, and intermodule passes through physics avionics bus (ARINC664/ARINC429)
It is attached.When operator sends a message to ground support system, message is encapsulated as ARINC661 data packet through navigating by display panel control
Electric network is transmitted to user and applies (User Application, hereinafter referred to as UA), user's analytic application ARINC661 data packet
It delivers and the processing of floor treatment base station is sent to by radio station after communications management unit (CMU) is handled.Fig. 2 gives interactive avionics frame
Structure logic diagram.
Cockpit display system includes multiple distributed display panel controls, is resident ARINC661 display control in each display panel control
It is served by, graphical display and standard ARINC664 communication interface based on ARINC661 is externally provided, resided in IMA cabinet
Multiple display panel controls are completed in the corresponding logic control application of display unit, the control shown by Logic application to graphical interfaces
Functions, the display controls such as same interface is shown, synchronous, the different interface displays of data are served by and the clothes in resident display panel control
Data interaction is carried out using ARINC661 communication protocol between business application.
It shows that data synchronize between display panel control and mainly solves same display circle that multiple operators operate different display units
The maintenance that data are shown when face or different interfaces, keeps it to show the alternative of the relevance of figure and graphical control operation.In
In ARINC661 specification, all display control property changes are all based on event triggering, can to the logic control of the aobvious control of figure
To be reduced to the pondization management to graphical control, Fig. 3 shows the aobvious control data Synchronization Design point based on the management of shape library pondization
Layer structure.
Operation layer is the set of one group of display unit, these display units can show the same window, can also be according to behaviour
The switching of work person's keyboard operation trigger event shows different window interfaces, and the aobvious control clothes of ARINC661 are resided in each display unit
Business, ARINC664 communication and heartbeat application show control service and are responsible for completing to window ARINC661 command analysis by graphic element
The display control of mouth, layer, control, ARINC664 communication software be responsible for complete the management of network communication virtual link, resolve packet and
It sends, heartbeat is applied to be detected for thrashing.
Control layer is made of different application terminal nodes (UAEP), and different UAEP is by applying logic control industry
The graphical display of business layer display panel control, single UAEP can control multiple aobvious control users, can also control one by multiple UAEP
Aobvious control user, since bottom ensure that the aobvious synchronization for controlling graph data using unified resource pool, control layer major function is to connect
The message event from display panel control is received, completes affair logic processing, and complete graphical display according to predetermined design, and by message
It is sent to ground receiver unit by radio station, completes the reception of station information at the same time.
Resource pool is the key that aobvious control data are synchronous, due to having carried out Chi Huashe to ARINC661 graphical control example object
Meter and management guarantee the consistency of graphic element attribute in shape library, multiple so that all UAEP share same resource pool
When aobvious control shows same graphical window and layer, it is only necessary to which the attribute of the periodic refresh interface graphical display can guarantee display figure
Consistency, when showing different interfaces, UAEP reads different example object respectively and carries out display properties refreshing, same with this
When, since ARINC661 editable control can realize the control modified control by editor control parameter, it ensure that difference
Aobvious control operates the mutual exclusion of same control.When graph layer of the event from multiple aobvious control users, standardize according to ARINC661 to layer
Definition, the aobvious control layer information of the acquisition that UAEP can be transparent, posts messages to specific in resource pool according to layer information
ARINC661 control, completion avoid UAEP to the modification of control display properties and the example object designs of simultaneously operating resource pool
Between the synchronous bring overhead of control property, simplify design cycle.
2) ARINC661 race condition solves
Race condition Producing reason is the request non_uniform response that data asynchronous interactive generates, in distributed display & control system
In, the influence of race condition bring can not be ignored, and since user program feeds back to the information of operator error, this may be misled
Operator.In addition user program automatically updates the request that will cause operator and send to some control datas in some scenes
With desired non_uniform response.
In order to solve the problems, such as distributed display & control system race condition, distributed display & control system is built using network calculus method and is prolonged
When model, complete the delay model analysis of display & control system Air China electric network, Fig. 4 describes distributed display & control system network module and hands over
Mutual delay model, in order to determine the upper of TSysLatencyMax and TPublisherLatencyMax delay parameter in network model
True, we introduce two concepts: arrival curve and service curves herein, according to Cruz R L in research network transfer delay
Definition network foundation element, it is assumed that the network element that the stream that an arrival curve is α is β by a service curves, then
Delay expression formula is d (t)≤h (α, β)=MAX { x2-x1}(α(x1)=β (x2),t≥x2≥x1≥0).H is time, x2For clothes
The time axial coordinate that business curve is β, x1The time axial coordinate for being α for arrival curve.
In AFDX end system, data communication end to end is carried out using virtual link (Virtual Link, VL), and a plurality of
Virtual link can exist simultaneously in same physical link, analyze an AFDX end system containing n virtual link, and physics is defeated
Bandwidth is C out.The configuration parameter of No. i-th virtual link VLi is minimum bandwidth allocation interval BAGi and maximum frame lengthAnd haveMinimum single wide assignment interval of the BAGi for i-th virtual link, (Bandwith Allocation Gap), then
The Delay Bound of each data flow of the end system can calculate, by taking Universal FIFO strategy as an example, No. i-th virtual link VLi warp in system
After crossing shaping, arrival curve is identical with fair curve, isThe then arrival of n virtual link aggregated flow
Curve isUnder FIFO scheduling strategy, it is whole that the end system of output bandwidth C is equivalent to a greed
Shape device, service curves are β=Ct.It can thus be concluded that Delay Bound of the data flow in virtual link in end system isThus computing system intermodular data can be predicted and transmit the worst potential time delay TSysLatencyMax
Potential time delay T is sent with dataPublisherLatencyMax.Aobvious control receives software data sampling period TSamplePeriodThen by reality
When the switching of operating system context and dispatching algorithm be calculated, user applied to refresh cycle of ARINC661 control
TRefreshPeriodIt is triggered based on event, it is deep that dynamic data node needed for avoiding generating race condition can be calculated as above data
Ni is spent, Ni is integer.
Context number information is carried out to the control supplemental characteristic for generating race condition in algorithm routine realization to tie up
It is fixed, so that control supplemental characteristic is associated with by force with context number numerical value, according to avionics network calculus data dynamic self-adapting
Node data chained list is adjusted, keeping effective data link table depth is Ni, memory event refresh data in the period.User applies more
When new control supplemental characteristic, the parameter for needing to update control is found first, it is whether small referring to valid data depth in current chained list
In dynamic link table depth Ni, newly-increased data memory node is added, deletes invalid node data, and by latest data and corresponding
Context number is recorded in data first node position, and Fig. 5 describes control supplemental characteristic and updates schematic diagram, the race condition
Data in race condition time-domain are completely stored in depth data chained list by algorithm model, when system generates race condition
When, user, which applies, responds request command by traversal parameter chained list matching context number numerical value, and then will count
It is recovered according to from race condition, to guarantee the consistency of request and response data.
3) health control failure detection layer:
Adaptively aobvious control unit (ADCMU) is resided in comprehensively modularized avionics system (IMA) cabinet, is control
The important composition unit of preparative layer is responsible for url management, failure detection, windows exchange, display layer control of display unit etc., as
The scheduling of resource layer of the aobvious control of distribution is based on failure detection algorithm to ADCMU in systems to ensure the reliability of ADCMU
Carry out reliability design.Traditional failure detection algorithm, which focuses mostly on, is obtaining maximum prolong by statistics arrival heartbeat message delay
Value late, and this value is realized into adaptive failure detection as the upper limit value of network timeout, detection time is by network fluctuation shadow
Sound is larger, occurs Chen-FD algorithm thereafter, which postpones the arrival to predict next heartbeat message according to discrete heartbeat
Time is calculated threshold value by dynamic on this basis to adjust the heartbeat timeout time, and is adjusted using a fixed correction value α
The advantages of time-out time, this algorithm, there is provided a preferable valuation budgets, may under some high precision application scenarios
It will lead to that detection time is elongated, the Ф-FD algorithm occurred later utilizes the normal distribution characteristic of heartbeat arrival time, when calculating
Between heartbeat reaches before T probability, and as suspecting that rank judges whether process fails compared with the threshold value P of setting.This
Traditional failure detection algorithm is used for reference in design, and in conjunction with ARINC664 real-time ethernet, temperature, processor are accounted under airborne aeronautical environment
With rate to the influence characteristic of network transmission, a kind of adaptive failure detection algorithm suitable for the aobvious control of avionics distribution is proposed, it is false
If display panel control Dk sends heartbeat message to ADCMU with fixed cycle Δ t, sending message content is to meet what ARINC661 was standardized
Handshake data packet, wherein the VL field of message header designates the display panel control in current message source, the Context of message content
Num field is incremented by, and the time that record the last time receives heartbeat message is Ti, and current time T remembers heartbeat reaching time-difference
For Δ Ti, (M ∈ (- 55~80), V are that V time obtains heartbeat difference record message to environment temperature M, and V is integer, and Δ θ is that Δ Ti connects
Receive the standard mean value of heartbeat difference:
Sliding window N is taken, i i-th obtains heartbeat difference record, then environment temperature M is to heartbeat message reaching time-difference Δ
Thus the impact factor λ M of Ti obtains one group of temperature impact factor set.
Arranging recording processor utilization rate U, (U ∈ (1~100), reference temperature(TR) impact factor calculation is similarly at acquisition
It is KU to the impact factor of heartbeat message reaching time-difference that device utilization rate, which is managed, in sliding window N,
λ M and KU runs with system and constantly updates, and establishes T moment heartbeat failure suspicious degree model are as follows:
Wherein ФTWhen approaching 1, the suspicious degree of communication link fails at this time between display panel control and ADCMU is higher, works as ФT
Greater than default failure threshold thresholding P when, start link abnormality alarming, re-establish communication link, reside in IMA
Multiple ADCMU carry out failure detection with display panel control simultaneously, and judge whether to need by voting by a show of hands in abnormality alarming
Reset operation carried out to oneself, switch VL (Virtual Link) under the scene for determining link failure, switching VL alarm is still
Do not restore, reset ADCMU, under the scene for determining aobvious control failure, disconnects current ink link, starting display panel control failure is accused
It is alert.
