Figure DEST_PATH_IMAGE016
Figure DEST_PATH_IMAGE017
Wherein the content of the first and second substances,
Figure DEST_PATH_IMAGE018
is the number of defect classes occurring within the anchor segment,
Figure DEST_PATH_IMAGE019
is shown as
Figure DEST_PATH_IMAGE020
The number of the seed defects is increased,
Figure DEST_PATH_IMAGE021
is shown as
Figure DEST_PATH_IMAGE023
The risk degree of the defects is planted, and the risk degree of a single defect is the ratio of the number of the defects in the space W in the time T range to the number of the defects in the whole line;
and 5: calculating maintenance resource utilization
Figure DEST_PATH_IMAGE025
Wherein the content of the first and second substances,
Figure DEST_PATH_IMAGE027
the total number of the M parts and maintenance planning workers of the equipment before the name is given;
if it is
Figure DEST_PATH_IMAGE029
The maintenance resource allocation is reduced;
if it is
Figure DEST_PATH_IMAGE031
If so, maintaining the resource allocation quantity unchanged;
if it is
Figure DEST_PATH_IMAGE033
Then the maintenance resource allocation is increased;
step 6: taking N defects of parts and equipment before ranking as an equipment quality index of the health state index of the contact network system, obtaining the corrected health state index of the contact network system, evaluating the health state of the contact network system, obtaining a health value and a health grade, wherein S (t) is the health value of the contact network system at the time t, H (t) represents the health grade corresponding to the health value at the time t,
table 1 table of correspondence between health degree value and health grade of indexes of health state of contact network system
Health grade Health value Health care (t 1 ,100] Sub-health (t 2 , t 1 ] Pathological state (0, t 2 ] Fail to work 0
Determining a hidden state transition probability matrix using a hidden Markov model construction method
Figure DEST_PATH_IMAGE035
Figure DEST_PATH_IMAGE037
Wherein m is the number of health values in the history record, and P is
Figure DEST_PATH_IMAGE039
Of time of day
Figure DEST_PATH_IMAGE041
In the state of the electric heating furnace,
Figure DEST_PATH_IMAGE043
is shifted in time to
Figure DEST_PATH_IMAGE045
The probability of a state is determined by the probability of the state,
the current health value of the contact net is S (0), then
Figure DEST_PATH_IMAGE047
The distribution probability of the contact net health degree of each health degree calculation time point can be calculated by the following formula:
Figure DEST_PATH_IMAGE049
when is coming into contact with
Figure DEST_PATH_IMAGE051
In the matrix, the extracted health value is lower than
Figure DEST_PATH_IMAGE053
When the sum of probabilities is greater than
Figure DEST_PATH_IMAGE055
In the meantime, the health status of the catenary is sub-healthy and below
Figure 151680DEST_PATH_IMAGE047
The individual health degree calculates the high contact net inspection frequency on the premise of time point, and allocates the maintenance schedule workers and the maintenance resource ration.
