In step S33, if the sum of the valve stem deflection angle information in the set time window is smaller than a set threshold value, it is determined that the jitter data is changed;
in the implementation mode, if the valve rod is positively and negatively deflected within a set time window and the final deflection result is smaller than the minimum value of the set threshold, the valve rod undergoes an ineffective rotation process, and no matter how large the deflection peak value is, the valve opening is not changed.
In step S34, if the sum of the valve stem deflection angle information in the set time window is within the set threshold, determining that the micro-rotation data is changed;
in the implementation mode, if the valve rod is deflected unidirectionally in a set time window, and the final result of deflection is larger than the minimum value of the set threshold value and smaller than the maximum value of the set threshold value, the valve rod is subjected to an effective rotation process, and the valve opening is changed under the long-term action.
In step S35, if the sum of the valve stem deflection angle information in the set time window is greater than a set threshold value, determining that the normal rotation data is changed;
in this implementation, if the valve stem is deflected unidirectionally within a set time window and the final result of the deflection is greater than the maximum value of the set threshold, the valve stem undergoes an effective rotational process and no trace movement directly causes a change in the valve opening.

In step S42, if the set recording duration exceeds the duration preset value, reporting the current circle position and the valve opening to the terminal, and setting all micro-rotation data and normal rotation data in the recording duration;
according to the implementation mode, micro-rotation characteristic trust values can be calculated by periodically sending micro-rotation data to the terminal, accumulated calculation can be carried out on micro-rotation angles, a confirmation work order is generated according to micro-rotation sequences, trust values and accumulated values, appointed personnel are assigned to carry out field confirmation and photo input, correction of the current micro-rotation circle position can be facilitated by establishing a correction micro-rotation characteristic model, the current micro-rotation circle position can be used in a later operation mode, the circle position of a valve is estimated through circle position rotation values (clockwise is negative and anticlockwise is positive), the minimum value and the maximum value of the circle position of the valve are automatically found, and a method for simultaneously returning to zero by the minimum value and the valve opening is used as a valve complete closing correction method, so that the valve opening value is automatically adjusted;
