OPC stands for OLE (object linking and embedding) process control. OPC is a data connectivity standard for communicating between controllers, devices, applications and other server-based systems without the need to enter custom drivers for data transfer. An automation system or process consists of different controllers and devices from different suppliers or different protocols of a supplier. These controllers and devices are critical to communicating with a business or management system. Thus, an environment is created by OPC to access real-time factory data from these suppliers.

then take Δ n ＝V n ；
If V n -V n-1 <0&&|V n -V n-1 |>V max Then it is considered asIs the data that is the exception data,
then take Delta n ＝Δ n-1 ；
Otherwise, take Δ n ＝V n -V n-1 ；
Wherein, delta n Is the difference of the accumulated amount of material within a time threshold, V n Is the current value, V n-1 Is the last value, V max A manually set difference threshold.
Through the above logic processing abnormal data, the consumption of the small time segment can be calculated, and the blanking amount of the material in the storage bin is divided into the material consumption by combining the material change record of the storage bin:
M i ＝∑F i *t i
wherein i is the material type, M i Is the daily consumption of the ith material, Fi flow of the i-th material, t i The material discharging time of the ith material is shown.

wherein the content of the first and second substances, w1 for daily consumption of material, c 1 For the first value of the sorted list, c2 for the second value of the sorted list,
Figure BDA0003898070360000052
all values after the second value of the sorted list are added.
In this embodiment, the product item of the accounting of the sintering cost is the sintered ore, the yield of the sintered ore can be directly obtained by measuring with a belt scale of the finished ore, and the material cost is calculated by the following method:
c day ＝w*p
