卷径计算有3种方式：

1. 线速度/角速度  然后滤波

   This function block is used to calculate the diameter of a winder by dividing the material

   velocity by the winding shaft speed.

2. 积分方式计算

   
   

   This function block is used to calculate the diameter of a winder by dividing the material

   length change by the number of winding shaft revolutions.

3. 厚度叠加（固定材料）

   
   

   This function block is used to calculate the diameter of a winder roll being wound by adding

   twice the material thickness per winding shaft revolution.
