The service layer comprises display logic developed by a user, a failure detection algorithm library, a competition condition algorithm library and a detection configuration file. The user layer is a collection of a set of display elements that accomplish the display of graphical controls based primarily on the ARINC661 specification.
1) ARINC661 control resource pooling data synchronization:
according to the ARINC661 standard definition, the avionic display control system is divided into a display system and a logic control system, the display system and the logic control system are respectively designed in a modularized mode, and the modules are connected through a physical avionic bus (ARINC664/ARINC 429). When an operator sends a message to a ground service station, the message is packaged into an ARINC661 data packet by a display control device and is transmitted to a User Application (UA) through an avionic network, and the ARINC661 data packet is analyzed by the User Application and is delivered to a Communication Management Unit (CMU) for processing, and then is sent to a ground processing base station by a radio station for processing. FIG. 2 shows a logic block diagram of an interactive avionics architecture.
The cockpit display system comprises a plurality of distributed display and control devices, ARINC661 display control service applications reside in each display and control device, graphical display and a standard ARINC664 communication interface based on the ARINC661 are provided for the outside, logic control applications corresponding to display units reside in an IMA case, the functions of displaying the same interface, synchronizing data, displaying different interfaces and the like of the plurality of display and control devices are completed through the control of the logic applications on the graphical interface display, and the ARINC661 communication protocol is used for data interaction between the display control service applications and the service applications residing in the display and control devices.
The display data synchronization among the display control devices mainly solves the problem of maintaining display data when a plurality of operators operate the same display interface or different display interfaces of different display units, and keeps the relevance of display graphs and the mutual exclusion of graph control operation. In the ARINC661 specification, all display control attribute changes are triggered based on events, the logical control of graphic display control can be simplified to pooling management of graphic controls, and fig. 3 shows a display control data synchronization design hierarchy based on pooling management of a graphic library.
The business layer is a set of display units, the display units can display the same window, and can also switch and display different window interfaces according to an operator keyboard operation trigger event, an ARINC661 display control service, an ARINC664 communication and a heartbeat application reside in each display unit, the display control service is responsible for analyzing an ARINC661 command, display control of the window, the layer and the control is completed through a graphic unit, ARINC664 communication software is responsible for completing network communication virtual link management, data packet analysis and sending, and the heartbeat application is used for system failure detection.
The control layer is composed of different application program terminal nodes (UAEPs), different UAEPs control the graphic display of the service layer display control equipment through application logic, a single UAEP can control a plurality of display control users, and also can control one display control user through a plurality of UAEPs.
The resource pool is the key of display control data synchronization, as the ARINC661 graphical control instantiated objects are subjected to pooling design and management, all UAEPs share the same resource pool, the consistency of the attributes of graphical elements in the graphical library is ensured, when a plurality of display controls display the same graphical window and layer, the consistency of the displayed graph can be ensured only by periodically refreshing the displayed attributes of the graphical interface, when different interfaces are displayed, the UAEPs respectively read different instantiated objects to perform display attribute refreshing, meanwhile, as the ARINC661 editable controls can realize the control modification control through editing control parameters, the mutual exclusion of different display controls operating the same controls is ensured. When the event comes from the graphic layers of a plurality of display and control users, the layer definition is carried out according to ARINC661 specifications, UAEP can transparently obtain display and control layer information, the information is transmitted to a specific ARINC661 control in a resource pool according to the layer information, modification of the display attribute of the control and design of the instantiated object of synchronous operation resource pooling are completed, extra expenses caused by attribute synchronization of the controls between UAEP are avoided, and the design flow is simplified.
2) ARINC661 Competition Condition resolution
The reason for the generation of the race condition is that the request response generated by the asynchronous data interaction is inconsistent, the influence caused by the race condition in the distributed display control system cannot be ignored, and the user program feeds back wrong information to the operator, which may mislead the operator. In addition, in some scenarios automatic updating of some control data by the user program may cause the operator-sent request to be inconsistent with the expected response.
In order to solve the problem of competition conditions of a distributed display and control system, a network algorithm is adopted to build a delay model of the distributed display and control system, so as to complete the delay model analysis of an avionic network in the display and control system, fig. 4 describes a network module interaction delay model of the distributed display and control system, and in order to determine the upper limit of delay parameters of TSysLatencyMax and tpublishlatencymax in a network model, two concepts are introduced here: according to the network basic element defined by Cruz R L in the research of network transmission delay, assuming that a flow with an arrival curve of alpha passes through a network element with a service curve of beta, the delay expression is d (t) h (alpha, beta) MAX { x ≦ x2-x1}(α(x1)＝β(x2),t≥x2≥x1Not less than 0). h is time, x2For a time axis coordinate with a service curve of beta, x1To arrive at the time axis coordinate with curve a.
In the AFDX end system, end-to-end data communication is carried out by using Virtual Links (VL), a plurality of Virtual links can exist in the same physical Link at the same time, and the AFDX end system containing n Virtual links is analyzed, wherein the physical output bandwidth is C. The configuration parameters of the ith virtual link VLi are the minimum bandwidth allocation interval BAGi and the maximum frame length
And is provided with
BAGi is the minimum single width distribution interval (Bandwith Allocation Gap) of the ith virtual link, the delay upper bound of each data stream of the system can be calculated, taking a general FIFO strategy as an example, after the ith virtual link VLi in the system is shaped, the arrival curve and the shaping curve are the same, namely
The arrival curve of the aggregated flow of n virtual links is
Under the FIFO scheduling strategy, an end system outputting the bandwidth C is equivalent to a greedy shaper, and the service curve of the greedy shaper is beta-Ct. The delay of the data stream in the virtual link in the end system can thus be bounded by
The potential worst time delay T of data transmission between the computer system modules can be predicted according to the methodSysLatencyMaxAnd potential time delay T for data transmissionPublisherLatencyMax. Data sampling period T of display control receiving softwareSamplePeriodThe refresh period T of ARINC661 control applied by the user is calculated by the context switching and scheduling algorithm of the real-time operating systemRefreshPeriodBased on the event trigger, the depth Ni of the dynamic data node required for avoiding the generation of the competition condition can be calculated by the data, wherein Ni is an integer.
And carrying out context number information binding on control parameter data generating competition conditions in the realization of an algorithm program, so that the control parameter data are strongly associated with a context number value, dynamically and adaptively adjusting a node data linked list according to calculation data of the avionic network, keeping the depth of an effective data linked list as Ni, and periodically memorizing event refreshing data. When the user is applied to updating the parameter data of the control, firstly, the parameter of the control to be updated is found, whether the depth of the effective data in the current linked list is smaller than the depth Ni of the dynamic linked list is referred to, a newly added memory data node is added, invalid node data is deleted, the latest data and the corresponding context number are recorded at the position of the first node of the data, a parameter data updating schematic diagram of the control is described in the figure 5, the data in a competition condition time domain are completely stored in the depth data linked list by the competition condition algorithm model, when the system generates a competition condition, the user applies and responds to a request command by traversing the parameter linked list and matching the context number, and then the data are recovered from the competition condition, so that the consistency of the request data and the response data is ensured.
3) Health management failure detection layer:
the self-Adaptive Display and Control Management Unit (ADCMU) resides in an integrated modular avionics system (IMA) cabinet, is an important component unit of a control layer, is responsible for link management, failure detection, window switching, display layer control and the like of a display unit, serves as a resource scheduling layer of distributed display and control, and is designed for guaranteeing the reliability of the ADCMU based on a failure detection algorithm. Most of the traditional failure detection algorithms focus on obtaining the maximum delay value by counting the delay of the arriving heartbeat message, and using the value as the upper limit value of the network timeout to realize the self-adaptive failure detection, the detection time is greatly influenced by network fluctuation, and a Chen-FD algorithm appears after the detection time, the algorithm predicts the arrival time of the next heartbeat message according to the discrete heartbeat delay, adjusts the heartbeat timeout time by dynamically calculating a threshold value on the basis, and a fixed correction value alpha is used to adjust the timeout, this algorithm has the advantage of providing a better estimation budget, in some high-precision application scenarios, the detection time may become longer, and a subsequent Φ -FD algorithm calculates the probability of heartbeat arrival before time T by using the normal distribution characteristic of heartbeat arrival time, and compares the probability with a set threshold P to determine whether the process is invalid by using the probability as a suspicion level. The design uses the traditional failure detection algorithm for reference, combines the characteristics of the influence of the temperature of an ARINC664 real-time Ethernet under an airborne aviation environment and the occupancy rate of a processor on network transmission, and provides a self-adaptive failure detection algorithm suitable for avionic distributed display control, supposing that display control equipment Dk sends heartbeat messages to an ADCMU at a fixed period delta T, the content of the sent messages is a handshake data packet conforming to ARINC661 standard, wherein a VL field of a message header indicates display control equipment of a current message source, a Context Num field of the content of the messages is increased progressively, the time of receiving the heartbeat messages for the last time is recorded as Ti, the current time is recorded as T, the time difference of arrival of the heartbeat is recorded as delta Ti, an environment temperature M (M belongs to (-55-80), V is the V for the V time of obtaining the heartbeat difference recorded messages, V is an integer, and delta theta is a standard mean value of receiving the heartbeat difference by delta Ti:
and taking a sliding window N, and obtaining the heartbeat difference record i times, so that the ambient temperature M influences the influence factor lambda M of the heartbeat message arrival time difference delta Ti, thereby obtaining a group of temperature influence factor sets.
Appointing to record the utilization rate U of the processor (U belongs to (1-100), obtaining the influence factor of the utilization rate of the processor on the arrival time difference of the heartbeat message in a sliding window N as KU by referring to the calculation mode of the temperature influence factor in the same way,
the lambda M and the KU are continuously updated along with the operation of the system, and a heartbeat failure suspicion degree model at the T moment is established as follows:
wherein phiTWhen the value is close to 1, the higher the suspiciousness of the fault of the communication link between the display and control equipment and the ADCMU at the moment is, when the value is phiTAnd when the fault is greater than a failure threshold value P set by the system, starting a link abnormity alarm, reestablishing a communication link, simultaneously carrying out failure detection on a plurality of ADCMUs residing in the IMA and the display and control equipment, judging whether the ADCMUs need to be reset or not by hands holding voting under the condition of the abnormity alarm, switching VL (virtual Link) under the scene of judging the link fault, switching VL alarm to be still not recovered, resetting the ADCMUs, disconnecting the current link under the scene of judging the display and control fault, and starting the display and control equipment fault alarm.
