Wherein, parameter information input unit 301 be used to receive from the sensor acquisition of environment monitoring module to data, these data should be passed through A/D conversion and preliminary treatment.Because in the ordinary course of things, multisensor is often described the same characteristic the environment from different coordinate frames, and their represented time, space and expression way possibly have nothing in common with each other, must they are unified in a common space-time referential.The comprehensive coordinate management of time factor, space factor and duty factor has been accomplished in the preliminary treatment of data, and transducer is selected, drops into optimum and the reliable sensors group to adapt to various conditions.Secondly, parameter information input unit 301 also should receive from the output of production plan processing module 102.
Owing to always have noise in the data of sensor measurement; So the estimated value that obtains according to the detection data exists evaluated error; And this evaluated error also is a random quantity, the quality of therefore estimating an algorithm for estimating generally all with mean square error as evaluation index.Detection information for multisensor; Because the certainty of measurement of each transducer is different with measurement environment; The accuracy of measuring certainly exists difference, if multisensor is made no exception, will not detect in addition processing and utilizing of data with making any distinction between; Must bring the inaccuracy of testing result to cause system handles result's error, this error can be very big sometimes.So need accuracy, selectively the importance of transducer distinguished to each transducer residing status and detection in detection system.The foundation of Here it is adaptive weighted data anastomosing algorithm.
One-level information fusion unit 302 adopts adaptive weighted data fusion method to be mainly used in the one-level fusion that the monitoring system bottom sensor detects data, thereby for secondary merges on-the-spot more accurately detection information and system status information is provided.The comprehensive evaluation result of weighted sum method can be expressed as:
Wherein, i=1,2 ... N, g
iBe single factor evaluation index, h
iBe corresponding weights.The variation of the evaluation index that provides in this method is linear, and when rough the evaluation, not losing is a kind of simple method.Wherein key is confirming of each factor weight.Weight Determination can be according to following 3 kinds of methods among the present invention:
(1) rule of thumb confirms
If measurement data does not contain the foundation of any definite flexible strategy.This type unequal precision measurement data are just rule of thumb confirmed flexible strategy.Measurement experience that this definite method need be enriched and knowing the talent of relevant error aspect can be competent at.Usually rawness confirms that flexible strategy are the flexible strategy branch fourth class: the survey data flexible strategy that are judged to be blunder error are 0; The flexible strategy of more insecure measurement data are 1; The flexible strategy of good measurement data are that the flexible strategy of best measurement data are 3.
(2) confirm according to measuring number of times
For equal precision measurement, because it is different to measure number of times, and make measurement result not wait precision, it is fairly simple not wait the flexible strategy of accuracy data to confirm for kind, can directly be used as measure number of times as flexible strategy.It is big more to survey number of times, and the data precision that obtains is high more, and flexible strategy are also big more.In fact, this is consistent with power not waiting the effect of being played in the accurate measurement amount, and it is specifically characterizing the degree of reliability of each data.
(3) confirm according to the precision parameter of data
To the handled accuracy data that do not wait; When the precision parameter of known each data; In order to confirm that each is according to deserved flexible strategy; Can not wait accuracy data to regard as and be equivalent under the equal precision measurement condition these, in measure number of times different and constitute do not wait precision, it is the equal of to measure the different and precision parameter of the measurement result that draws of number of times that the precision parameter that provides each data is regarded as.
Just can obtain the data fusion value of other environmental parameter with quadrat method.The weighted factor separately that draws according to the variance of each transducer; The higher transducer of certainty of measurement has higher weighted factor; And, all calculating its weighted factor in each the measurement according to each measurement data along with the increase of number of times, its significance level in detecting data processing is embodied by weighted factor; So just more can be according to the advantage of multisensor; Take into full account the interference of factors such as environment, reduce of the influence of the bigger data of deviation, improve the accuracy of measuring system accuracy of measurement.
With the temperature sensor is example, in the present embodiment, 8 temperature sensors has been installed in the greenhouse, from sensor to data and merge according to carry out one-level based on adaptive weighted algorithm, the corresponding weight value and the variance that calculate are as shown in the table:
The fusion value that calculates is: 0.704
Second-level message integrated unit 303 is a decision level fusion, and its purpose is on the basis of one-level fusion results, makes system's output decision-making.Merge for secondary since the amount of information of input type is different each other, merge so can not directly carry out data level, through with it in the enterprising line translation of domain, make its obfuscation.On the basis of fuzzy set theory, carry out the decision level information fusion then based on the expansion principle.
In the present embodiment, establishing X is domain, and m: σ → [0,1] is a fuzzy mearue, and A ∈ σ, h are that σ can survey, and then the fuzzy integral of h on A is defined as:
Wherein, H
λ={ x|h (x)>=λ }.Following formula is the Sugeno fuzzy integral about fuzzy mearue m.
As domain X={x
1, x
2... X
nBe finite aggregate, and h (x
1)>=h (x
2)>=...>=h (x
n), can obtain the Sugeno integration of h on X by formula (2) and be defined as:
Wherein, X
i={ x
1, x
2... X
i.Because fuzzy mearue m (X
i) complexity of calculation, according to structure g
λThe way of estimating further obtains Sugeno integral Calculation formula and is:
Wherein, H (x
1)=g
1, H (x
i)=g
i+ H (x
I1)+λ g
iH (x
I1).
In addition, the Choquet integration estimated of F:
Wherein, H
λ={ x|h (x)>=λ }.
As domain X={x
1, x
2... X
nBe finite aggregate, and h (x
1)≤h (x
2)≤...≤h (x
n), can get h Choquet integral and calculating formula about g on X by formula (5) and be:
Wherein, H (λ
i)={ x
i, x
I+1..., x
n, h (x
0)=0
When utilizing fuzzy integral to carry out overall merit, fuzzy mearue can characterize the attention degree of each single factor evaluation index, and confirming of fuzzy mearue is the key of this evaluation method.
Information fusion evaluation unit 304 is for assessing and compare the decision information that obtains through secondary integrated unit 303, and the root mean square error RMSE that adopts estimated value and original value in the present embodiment is as passing judgment on tolerance.
Control signal output unit 305 is according to the output of information fusion evaluation unit 304 important evidence as control signal; Satisfy the signal that the built-in Optimization Model of system presets and be transferred to the output of control signal output unit and be used to control distributed intelligent controller, thereby reach the purpose of led light source being carried out intelligent control.
