Description
Technical field
The present invention relates to one kind being mainly used in the modeling that aviation electronics communication and navigation identifies the field (CNI), especially
It is the whole process dynamic simulation test neck that can be applied to CNI system integrators and function waveform provider under half life situations
Domain.
Background technology
Communication and navigation identifying system (Communication, Navigation and Identification, i.e. CNI
System) be avionics system important component.Important subsystem of the CNI subsystems as avionics system, be related to data processing,
The component parts such as signal processing, radio-frequency front-end processing, integrated functionality is numerous, and system structure is complicated, needs to realize data and speech
The functions such as communication, enemy and we's identification, flight and landing navigation.Collect in the Comprehensive Signal Processing machine that domestic a new generation CNI systems use
At waveform sensor function up to tens.The CNI systems of synthesization load different waveforms by identical physical resource
Software realization resource multiplex, effectively reduces system weight, reduces volume and power consumption, but system resource state management, scheduling,
Formation function and control flow all become more complicated, and requirements at the higher level are proposed to the design and development of CNI systems.In addition, not
CNI systems with platform usually have different hardware structures, and software and the hardware system degree of coupling are higher, so as to cause being
The problem of joint-trial heavy workload in system integrating process.How to shorten the system integration test time, improves system integration test reliability and system
Integrated efficiency, is one of the critical issue for needing to solve in CNI systems development process.
It is divided from functional perspective, CNI systems are mainly by providing CNI system digits and signal processing, radio-frequency receiving-transmitting processing etc.
The hardware platform with sensing capability is calculated, CNI system resources and function unified plan, the system control of scheduling and managerial ability are provided
Management software processed, and realize specific CNI system functions, such as UV speeches/number biography, tactical air navigation TACAN, precise distance measurement
DME/P and enemy and we identify the waveform software three parts composition of IFF responses etc..Hardware platform realizes that platform connects by board support software
The encapsulation of mouth, waveform software are usually made of fixed algorithm software, and are run in specific processing platform.CNI systems control
Management software according to system design considerations realize with hardware platform software, the control data interaction of waveform software, condition managing and
The functions such as scheduling deployment.The work of CNI system integration tests is concentrated mainly on interactive interface and the operating status test of each component part.
The appearance of container technique provides better platform for waveform software operation.Container software encapsulates hardware platform difference, is wave
Shape software provides standardized platform interface, and system integration person needs the system integration norms according to software, and it is soft to complete waveform
The integrated verification of part and platform software, to mitigate the joint-trial pressure of waveform software.The further specification of Software communication architecture SCA standards
The minimum service set and its common model of waveform components instantiations, configuration, connection and resources control pass through to be layered and establish system
The profession point of Waveform Development and platform development separation is effectively realized in system container platform, facing assembly Interface integration waveform and application
It can be with concurrent development and test, to improve system integration efficiency after work, platform software and waveform software decoupling.However, due to
CNI systems are the systems of a high integrity, and are usually completed by multiple producer's cooperations, often are faced in system integration test various
The problem of various kinds.First, usually only under conditions of hardware environment and waveform software have, system money could gradually be carried out
The joint-trials such as source, functional resources scheduling.Secondly, it in order to test CNI systems control management software, needs to develop special boat
Electric simulator access control management software, control management software need to write corresponding interactive program.This test method is not
There is the processing for reflecting control supervisor when changing to real equipment state, increases additional control flow instead, need
The status information for receiving avionics simulator and real equipment simultaneously increases the negative of CNI systems control management software developer
Load.Avionics simulator is typically the customized software write for specific model project, and extension flexibility is poor, function
Simply, simple control command information can only be sent, main purpose is auxiliary system tester, to the side of software developer
It helps less.In addition, Waveform Development personnel are faced with identical problem, only function algorithm and real system hardware environment are completed
Interface testing can be carried out when having.Currently, still lacking effectively complementary modeling and test environment, especially exist
Under conditions of hardware environment does not have, in order to meet different joint-trial demands, CNI system integrators usually require to prepare to cover standby more
With joint-trial rack.In addition, CNI systems control management and the exploitation and test job of Waveform Development personnel all by hardware environment and
Respectively research and develop influencing each other for progress.
The professional division that hardware environment, control management platform and Waveform Development are separated from each other, to promote the reliable of CNI systems
Property provides the foundation with development efficiency.Although can be alleviated by being equipped with the approach such as more set hardware environment, exploitation avionics simulator
Problems faced and contradiction in CNI system integration tests, but as system integrator for, still face from hardware provider, waveform
The multi-party pressure such as software vendor, many deficiencies present in practical engineering application are：
1, lack effective CNI system modeling methods, as the static physical environmental modeling and dynamic command of chip-scale are rung
Answer, the modeling of operational process with operation driving method.
2, CNI system hardwares usually require to spend time several months from delivery is designed into, this sky window phase can not be software people
Member provides effective test environment.After hardware environment has, the time for leaving system software joint-trial for is shorter, leads to joint-trial pressure
It is very big.How to make full use of the system integration test that this section of empty window phase carry out software in advance is to improve the important of system development efficiency to ask
Topic.
3, during CNI system integration tests, smaller, the complicated true operation field of probability that specific physical resource state occurs
Scape is not easy to reappear in the debugging stage, and system software test is caused to be not enough.
4, CNI systems are an extremely complex electronic systems, synchronization usually by many different developers into
Row joint-trial, whole joint-trial process are influenced in many ways.System mode is constantly updated during joint-trial simultaneously, prepares and restore object every time
It is the cumbersome work of item to manage environment, and for CNI systems, control management software developer brings more extra work amounts.
5, during joint-trial, in order to meet the joint-trial demand of different personnel, CNI system integrators would generally prepare cover firmly more
Part equipment, to cause additional cost overhead, and existing common hardware resource is not fully utilized at present.
