This patent is based on HAZOP analytical technologies, it is proposed that airborne vehicle user's technical data safety evaluation flow process, node are carried
Take method, offset determination methods and analytical technology.User's technical data, as the random products for paying user, is that airborne vehicle is used
Main Basiss with safeguarding, there may be during being to look for user's technical data use based on the core of HAZOP analytical technologies
Deviation, and deviation is analyzed, determines reason and impact, recognize that the risk of current safety protective measure simultaneously proposes that improvement is built
View.
(1) analysis object, collection system data are determined.Including helicopter, system and device performance parameters, design and
Operation instruction, system/device layout drawing, standard technology handbook, safety evaluation data etc..
(2) object, partitioning site are decomposed.Operating process decomposition is carried out to job card, if dry contact is extracted, and to each section
Point is accurately described, and makes each node have independent design idea.Each node is generally job card operating process
Key operations, characteristic parameter, and adverbial word, the noun (object) of Expressive Features parameter of description key operations degree.It is crucial dynamic
Such as open, close, close, press, check；Characteristic parameter such as speed, moment of torsion, oil mass, angle, overload factor, lever operation
Amount etc.；Description key operations degree adverbial word such as promptly, little by little, lentamente, less than, be not more than, be not less than；Description
The noun (object) of characteristic parameter should be related to design configuration or maintained equipment, instrument in extract operation program or operation instruction
Noun, such as steering wheel, electrodynamic pump, stick, rotor rotating speed etc..
(3) clear and definite nodal function.Confirm selected node, specify its design idea, perfect condition.Design idea or reason
Think that state is determined according to system documentation and the design requirement collected, it is the acceptable criterion of the node, including the conjunction of key operations
The boundary condition of reason state and characteristic parameter.For example to operating process " controlling rotor rotating speed 90%～120% ", " rotor turns
Speed 90%～120% " is extracted as node, and according to the system documentation for collecting, " rotor rotating speed should be maintained at 90%～120%
(275r/m i n～367r/m i n) ", so the node meets design idea.
(4) determine significant deviation.All previously given introducers are applied successively, determine that each node is significant partially
Difference, i.e., the deviation that each node is likely to occur, deviation are the combination of introducer and node.HAZOP analysis methods are based on introducer
, main introducer includes "None", " deficiency ", " exceeding ", " adjoint ", " part ", " contrary ", "abnormal".Deviation=guiding
Word+node (adverbial word+verb, eigenvalue).Introducer is combined one by one with node, deviation is constituted, according to design idea, is filtered out
Significant deviation, as the object of variance analyses.It is for example with " rotor rotating speed 90%～120% " as node, significant inclined
Difference including " being not specified by the rotor range of speeds 90%～120% ", " the rotor range of speeds of regulation be less than 90% ", " regulation
The rotor range of speeds is higher than 120% ".
(5) deviation is analyzed.Dangerous key element, trigger mechanism and threat target danger three elements are analyzed, are known
The dangerous three elements not deviated, and analyze the reason for each node causes deviation and impact.Should analyze causes all originals of deviation
Cause, may cause different impacts, and then whether the existing safety precautions of analysis is sufficient, and propose under different reason situations
With regard to the recommendation on improvement of safety measure.The corrective measure one of the analysis of causes, impact analysis, existing safety precautions and suggestion
As it is as follows：
The analysis of causes：Carry out meeting during the analysis of causes different because node type, deviation are different, but should in concrete analysis
Consider based on node itself and input and output.It should be noted that herein the reason for be not only equipment fault, more to
Consider the mistake of human operational error and job card establishment.It is general to consider from the following aspects：Mechanical clamping stagnation, control failure,
Exotic entrance, the failure of burn into pipeline, operational error, operation require that imprecise, operation requires to retouch beyond plan boundary, word
State and be not inconsistent with material object；
Impact analysis：The impact that analysis deviation brings is considered as to flight unit, ground service engineering, helicopter, equipment and ring
The impact in border, and do not consider existing safety precautions.Whole machine/systemic-function hazard analysises (FHA), system/set can be used for reference
Standby failure mode and effect analysis (FMEA), system/device fault tree analysiss (FTA), region security analysis (ZSA) and occupation
The safety evaluation material such as health hazard analysis.It is general to consider from the following aspects：Fire, blast, toxic gas, the energy are damaged
Mistake, helicopter/device damage, casualties etc..
Existing safety precautions：Refer to security protection code of safety prevention measure or regulation of design etc., to inclined
When difference is analysed, the generation that can existing safety precautions effectively eliminate or control danger should be analyzed, to identify design
Leak and potential safety hazard in terms of defect or operation sequence, to be corrected in time.General safety precautions has：Report to the police
Device, preventer, security protection code, personal protection measure, inspection detection, flight unit/ground service engineering training etc..
Suggestion and measure：It is general to consider from the following aspects：Work for correction card and security protection code, Amending design side
Case, monitoring system, designer's protective measure are set, are formulated emergency response scheme, redundant system, more new equipment, reselected
Servicing area, test, reinforcement training and training.
(6) interpretation of result work out report.According to above-mentioned analysis result, it is confirmed whether also there is deviation.If nothing, analyze
Complete, work out HAZOP analysis reports.
Based on the airborne vehicle O＆M flow process safety analysiss technology of HAZOP analytical technologies, boat can be effectively recognized
The safety risks of the middle key operations and characteristic parameter of pocket user's technical data, propose that recommendation on improvement is eliminated or controls danger
Danger, it is to avoid the artificial deviation, design deviation during the establishment of user's technical data and use, effectively increases user's technical data
Safety, and then realize improve airborne vehicle operation and maintenance safety final purpose.
It is last it is to be noted that：Above example only to illustrate technical scheme, rather than a limitation.To the greatest extent
Pipe has been described in detail to the present invention with reference to the foregoing embodiments, it will be understood by those within the art that：Which is still
Technical scheme described in foregoing embodiments can be modified, or equivalent is carried out to which part technical characteristic and replace
Change；And these modifications or replacement, do not make the essence of appropriate technical solution depart from the essence of various embodiments of the present invention technical scheme
God and scope.
