f(a1,a2,…,at)=f (at|Ft-1)f(at-1|Ft-2)…f(a1|F1)
In above-mentioned joint density function, Ft-1, Ft-2..., F1Respectively in white noise acoustic disturbance at-1, at-2..., a1The corresponding moment The electricity consumption mathematical model calculates collected all data information set;
Wherein, defined functionThen
The electricity consumption abnormality detection module is to above-mentioned joint density function f (a1,a2,…,at) carry out about maximization nature The solution of logarithm calculates, to calculate the parameter θ1, θ2..., θp,With the side of white noise acoustic disturbance Poor σ2
Alternatively, the electricity consumption abnormality detection module calculates the variances sigma of the white noise acoustic disturbance also according to following formula2Specially
Alternatively, the electricity consumption abnormality detection module calculates the Euclidean distance d and institute also according to the electricity consumption mathematical model State s in advance and walk predicted mean vote | z |, specific formula for calculation is
In above-mentioned formula, p1,p2,…,psPredicted value, g are walked to shift to an earlier date s about the electricity consumption of the electricity consumption data model1, g2,…,gsFor the corresponding electricity consumption magnitude of newest s history electricity consumption data of each electrical equipment, s be one it is preset just Integer.
10. being used for the monitoring management system of use for laboratory electric equipment as claimed in claim 7, it is characterised in that: the electricity consumption Abnormality detection module is measured according to the Euclidean distance d, the s in advance walks predicted mean vote | z |, the white noise disturbance quantity σ2Really The fixed electricity consumption status information specifically includes, and the electricity consumption abnormality detection module judges the Euclidean distance d and 2 σ or institute State s in advance and walk predicted mean vote | z | with the size relation between 2 σ, if the σ of d > 2 or | z | when > 2 σ, the electricity consumption is abnormal Detection module determines that corresponding electrical equipment generates the electricity consumption status information there are multiplexing electric abnormality situation and with this, otherwise described Electricity consumption abnormality detection module is determined corresponding electrical equipment there is no multiplexing electric abnormality situation and is generated with this and described use electricity condition Information.
