Information；
Third processor 303, the evaluation index information for acquisition are pre-processed；
Third sending module 304, for pretreated evaluation index information to be sent to the processing end.
Each module 302 that obtains may obtain a large amount of evaluation index information in the same time, need to believe these evaluation indexes
Breath is matched with corresponding low-pressure metering box.In certain embodiments, third processor 303 includes that characteristic information marks mould
Block marks low-temperature measurement belonging to the evaluation index information for the evaluation index information for obtaining module acquisition to be marked
The characteristic information of case, so that the evaluation index score value of same low-pressure metering box is carried out calculation process by first processor.The spy
Reference breath includes location information or serial number information etc..
Module 302 is obtained equipped with multiple, it can be achieved that more fully acquisition of information, including network acquisition module, mobile acquisition
Module and fixed acquisition module.
(a) network obtains module, for obtaining the evaluation index information on network automatically.These information may is that salt fog,
The evaluation indexes information such as temperature, humidity.
(b) mobile to obtain module, the information that can be obtained includes: salt fog, rainwater immersion, solar irradiation, dust, is hit
It hits, vibrate, overcurrent or short circuit, lightning stroke, protective loop validity, box appearance and coating damage, box appearance and coating, nameplate
Mark, observation window, chamber door, stealing, estate management level etc..
The mobile module that obtains can be with are as follows:
Camera, for obtaining the image information of low-pressure metering box and its environment to be assessed, and by picture or transmission of video
Give third processor；
Third input module, for obtaining artificial input information.
Wherein, third input module can connect a third display module, for showing evaluation index, and show input frame,
Input frame is used to show the actual information of the evaluation index of input.
These information of third input module input are that operator inputs according to actual information, are also possible to by experience
The information of judgement, such as " estate management is horizontal ", " connecing money specification " etc. need that experience is combined to carry out subjective judgement, can also be defeated
When entering the information, corresponding alternate item is provided and is selected.
In the present solution, by the way that each evaluation index quantitative criteria is manually entered, but since the professional of operator is not so good as to comment
Estimate the technical specialist that end carries out assessment marking.If technical specialist judges that there are biggish error only with the information.Cause
This, this solution provides image or transmission of video to assessment end, technical specialist using image or video as main assessment foundation,
The information of operator's input is to refer to, to can get an accurate assessment result.
In certain embodiments, in order to which the image or video that make shooting are more clear, completely, third processor further include:
Picture quality detection module, for judging picture quality, when preset value is not achieved in picture quality, generation is clapped again
The feedback information taken the photograph is sent to corresponding acquisition module；
Image integrity checks module, for judging it is presetting whether the image obtained meets, when being unsatisfactory for, generates benefit
The feedback information for filling shooting is sent to corresponding acquisition module.It is described presetting including preset image angle and quantity information.
In this way, undesirable image will be required again or supplement is shot, so that technical patent be made to obtain one
Clear, complete information is conducive to accurate evaluation marking.
(3) fixed to obtain module
The fixed module that obtains includes sensor module, is installed on low-pressure metering box to be assessed, obtains heat transfer agent.These
Information may is that rainwater immerses (with humidity sensor or camera), temperature (temperature sensor), (illumination senses solar irradiation
Device), humidity (humidity sensor), vibration (vibrating sensor) etc..
The working principle of the above-mentioned low-pressure metering box status assessing system based on AHP- grey fixed weight cluster are as follows: processing end root
It imposes a condition according to first and obtains evaluation index information from acquisition end, and impose a condition according to second and be sent to assessment end, assess end
Reception technique expert to the expert estimation value of each evaluation index and is sent to processor based on the evaluation index information, processor
It is handled based on AHP- grey fixed weight cluster, obtains the health status of low-pressure metering box to be assessed.
Such as scored by 17 indexs of the p technical specialist to low-pressure metering box, if kth (k=1,2 ..., p) it is a
The score value that assessment experts provide a evaluation index of q (q=1,2 ..., 17) isThe expert estimation of evaluation index can be obtained
Matrix D:
By table 2, low-pressure metering box operating status is divided into 4 classes, respectively corresponds 4 grey classes, and whitened weight function is respectively
For evaluation index Xij(i=1,2 ..., 5；J=1,2 ..., 6), by formula (5), can find out N (N=1,
2 ..., 4) a grey evaluation coefficient X for assessing grey classi,N。
Formula (5) are substituted into formula (6), each total grey evaluation coefficient X for assessing grey class can be found outi:
The grey evaluation that then n-th assesses grey class weighs ri,NFor
If assessing synthetic clustering coefficient of the object about N ash class:
According to maximum membership grade principle, have
It can judge which kind of ash evaluation index belongs to.
This method calculates the evaluation index weight of each layer of low-pressure metering box using AHP, and steps are as follows:
(1) the judgment matrix A=(a of each factor is constructedij)n×n
In order to obtain each index to the significance level of upper one layer of factor, takes two indices to be compared every time and quantizes,
The Scale Method proposed using Saaty, as shown in table 3.Whole comparison results can arrange into judgment matrix A=(aij)n×n, and aii
=1,
3 Saaty scaling law of table
(2) consistency check
For the validity for verifying each index weights, need to carry out consistency check according to formula (10) to matrix A[8-10]:
In formula, CI is coincident indicator；λmaxFor the Maximum characteristic root of matrix A；N is matrix order；RI is mean random one
