Description
Technical field
The present invention relates to the band graphic data treating method and apparatus and storage medium of a kind of conveyer belt.
Background technique
Conveyer belt when being especially applied to weighing belt, will use the amendment of band shape and auto zero tracks two kinds of technologies.
Wherein the amendment of band shape refers in the tracking of calibration of belt scale, clearing or auto zero, stores the band of the belt of conveyer belt
Graphic data, and the weighing data in application process is subtracted into band graphic data, and then eliminate or partially remove due to entire belt week
The influence of the different weighing precisions to weighing belt non-integer week such as the thin and thick of the different location in the phase, soft or hard, weight.
Auto zero tracking refers to during the operation of weighing belt sky scale, to the average zero number of the belt cycle of conveyer belt
According to being modified, so eliminate or partially remove due in belt cycle average zero data variation to the integer multiples of weighing belt
The influence of weighing precision.
Both technologies are the different implementation methods to grow up from existing period zero point technology, and then are deposited between the two
In inner link.
But following problems can be encountered at present by applying in both technologies in conveyer belt:
1, the prior art is with being usually to take the method directly updated for the amendment with graphic data in shape amendment, i.e., to work as
Preceding weighing data is directly as band graphic data.However between current weighing data and actual band graphic data, there are errors, this is just
Lead to the band graphic data low precision generated, and then influences the modified precision of band shape of conveyer belt.
2, the prior art is not limited the amendment with graphic data by initial or calibration band graphic data, this will lead to generation
Band graphic data is uncontrolled, to reduce the reliability of weighing, is also unfavorable for the diagnosis with shape exception.
3, variation of the prior art with graphic data would generally cause mean value Zero change of weighing, and in turn result in band graphic data and repair
Just interfered with each other between the amendment of mean value zero data.Such as: one block of material is speckled on belt, symmetrical weight-average value zero point is repaired at this time
Just, the band modified error of shape can be increased significantly.At this point, weighing mean value zero point should be kept constant, change tape graphic data is
Best weighing effect can be reached.
Summary of the invention
