Description
Technical field
The present invention relates to computer control field, a kind of aircraft safety landing based on function resonance analyzing processes
Method.
Background technology
System safety engineering discipline development this in decades, occur in that a lot of security of system appraisal procedures.Tradition
Security of system appraisal procedure be widely used in system safety engineering field.But, along with large-scale complex society skill
Art system occurs, the most gradually shows the limitation of these methods.Function resonance analyzing method is a kind of novel popular answering
Miscellaneous sociotechnical system modeling method, it is possible to the safety to complicated nonlinear system is effectively assessed.But, it analyzes existing
Analyzing manually being only limitted to, completeness and concordance can not get preferably ensureing.Safety analysis based on model is form
Change method, in the extension in existing system safety evaluation field, is the security of system assessment technology of automatic operating.For solving
The limitation that classical secrecy appraisal procedure manual analyzing takes time and effort, easily makes mistakes, correctness can not be guaranteed.
Function resonance analyzing method (Functional Resonance Analysis Method, FRAM) is a kind of novel
Complex social-technical system modeling method, it is possible to the safety to complicated nonlinear system is effectively assessed.FRAM is from going out
Since Xian, in terms of accident investigation and systematic analysis, show powerful vitality, particularly in the investigation to aviation accident,
The order of analysis system and control, analyze the fields such as air traffic control system (ATCS), it is possible to finds that traditional analysis can not be sent out
Existing problem.But, its analysis is only limitted to analyze manually now, and subjective random strong, completeness and concordance can not get
Preferably ensure.So, so that the practicality of FRAM is higher, has develop formal modeling technology based on this method completely
Need.
At present, generally using radio altitude system to carry out survey aircraft distance to the ground during aircraft landing, this system is to fly
Machine regards as a particle, only detection belly distance over the ground.In order to judge attitude situation during aircraft landing, pilot wants
By observing pitching, the inclination angle that attitude instrument shows, rule of thumb judge between each undercarriage of aircraft close with ground
Situation, climb meter to be observed, prevent excessive the causing of fall off rate from heavily landing, impact landing gear structure.Weigh
The structure of aircraft may be produced and have a strong impact on by land, and after occurring heavily to land, aircraft need to carry out the many places inspections such as structure, the big wing, undercarriage
Looking into and could use, therefore whether detection aircraft occurs heavily to land extremely important.
In sum, prior art having following defects that, existing resonance analyzing method and model are difficult to assessment system
Safety, particularly when assessing aircraft landing, radio system is difficult to real-time judge whether aircraft conflicts with ground, and this causes
The technical merit of pilot is required the highest, particularly bad weather when, is easily caused aviation accident, therefore, compels to be essential
Design new model and carry out the security evaluation of aircraft landing.

Detailed description of the invention
Model inspection (Model Checking) is a kind of process verifying whether finite state system meets particular community.
The ultimate principle of the method is to search for state, determines if to meet some attribute.In other words conj.or perhaps, system is built
The system that mould language describes, if meet the attribute of Property specification language.Method is divided into simulation and test two parts.Its limitation
The state being also manifested in system must be limited, is therefore primarily adapted for use in finite state system.Model inspection completely can be certainly
Dynamic operation, efficiency is high.When character is unsatisfactory for, model checking tools typically can provide counter-example (counterexample), helps
User the fault of system or mistake are carried out deeper into understanding.
Model inspection is made up of, respectively at model system model, system property and three piths of model checking tools
Three steps of detection play the part of important function.These three step can be expressed as follows in detail.
(1) system model describes.Formal Languages is used concrete system to be entered by abstract system model in this stage
Line description.System model specification language is different according to different model checking tools.
(2) system property describes.The system property of checking will be needed, describe with specific logical expression.Different moulds
Type detection instrument has different situation to attribute description.
(3) checking.Generally, proof procedure is performed automatically by model checking tools.But, the result is divided
Analysis and research are accomplished by people and carry out.The needs of binding analysis, carry out simulation repeatedly and the test process of necessity.
The Heterosis of model inspection exists, and proof procedure is entirely and automatically carries out, and verifying speed is fast.When system model not
When meeting system property, model checking tools can provide one or more counter-example, to causing ungratified mistake to be identified,
Research worker is facilitated to be analyzed.
The description of " actual scene " comprises following components:
The original state of system, describes how function triggers, or which function is exactly initially abnormal.
The environmental condition that system is run, details external condition and possible situation of change thereof that system is run.Such as, sky
Gas condition, temperature and humidity etc..
System is it is normally assumed that elaborate some necessary hypothesis of an actual scene.Such as, in a practical situation, some
The change of function may occur never, or change is the least, it is possible to proposes to assume that the change of these functions can be neglected
Slightly.
The actual moving process of system.Extremely it is specifically described the running of system, it might even be possible to be included in certain special
Fix time and what there occurs.
The most how the Formal specification language of " actual scene ", express the key element in " actual scene " with finite state machine.Not
It is that above-mentioned all the elements are required for carrying out Formal specification language, only according to actual demand, some content once is carried out formalization, its
Function resonance method can be used to be analyzed, as follows:
The original state of system, it may be possible to system all possible original state set, with expression, needs at all of shape
Carry out after state identification, simply illustrate that at this this initializes from intension, say it is the part of actual scene Formal specification language.
The environmental condition of system operation and change thereof.The environmental condition of system can use the state representation of environment, environment
Original state with representing, the trigger condition of environmental change with representing, the final state of environment with representing, correlation behavior transfer function
With representing.Such as, " initial weather is fine day, and to noon, just When the Rain Comes." fine day can be expressed as, in time is up
At the noon, for the rainy day, all state sets of environment are, state transition function is.
System generally assumes that, it may be possible to some input of system, and is the most changeless input, Ke Neng
Whenever system plays a role, with representing.
The actual moving process of system, it is not necessary to carry out Formal specification language at this, needs to carry out table below with FRAM model
Reach.
