Claim 1:
2. The method according to claim 1, wherein determining the correction coefficient according to the relationship between the first deviation value and the intervention range comprises:
determining, under a condition that the first deviation value is within the intervention range, the correction coefficient according to formula (1):, θ
     =
     
      
       step
       ideal
      
      k
     
    
   
   
    
     (
     1
     )
    
   
  
 

determining, under a condition that the first deviation value is greater than a maximum value of the intervention range, the correction coefficient according to formula (2):, θ
     =
     
      
       α
       +
       β
      
      k
     
    
   
   
    
     (
     2
     )
    
   
  
 

determining, under a condition that the first deviation value is smaller than a minimum value of the intervention range, the correction coefficient according to formula (3):, θ
     =
     
      
       α
       -
       β
      
      k
     
    
   
   
    
     (
     3
     )
    
   
  
 

wherein θ is the correction coefficient, (α−β, α+β) is the standard range, and (α−Ω, α+Ω) is the intervention range, α, β, Ω are constants, α>0, Ω>β≥0, and α is the central value of the standard range and the intervention range, k is the acquisition ratio, stepk is the first deviation value, and stepk=|α+Ω−k|, stepα is a second deviation value obtained by mapping the first deviation value into the standard range, and, step
    α
   
   =
   
    
     step
     k
    
    
     Ω
     /
     β
    
   
  
  ,, stepideal is an ideal ratio, and stepideal=α+β−stepα.
