Embodiment 1

[0042] Such as figure 1 As shown, the strip shape data processing device of this embodiment includes: a strip shape correction module 1 , a zero point processing module 2 and a zero point strip shape tracking module 3 .

[0043] Wherein the belt-shaped data processing device of the present embodiment is applied in a belt scale, and its process for processing the weighing data in the belt scale includes the following steps:

[0044] Step 1, obtain the position data S(t) of the belt from the belt scale, and then determine the belt shape data Wp[S(t)] of the current position of the belt, and obtain the weighing data Wp[S(t)] of the current position of the belt from the belt scale (t) is subtracted from the band shape data Wp[S(t)], that is, the band shape correction is performed to obtain the band shape correction weighing data Wa(t). That is, Wa(t)=W(t)−Wp[S(t)].

[0045] Step 2, subtract the belt shape correction weighing data Wa(t) from the belt scale’s weight mean zero poin...

Abstract

The invention discloses a belt shape data processing method and device and a storage medium. The belt shape data processing method comprises that band shape data in a present position of a conveyor belt is determined according to position data, and the band shape data is removed from weighing data in the present position of the conveyor belt; zero point data of the weighing mean value is removed from the corrected weighing data to obtain practical weighing data; and the belt shape data and the zero point data of the weighing mean value are calculated and updated on the basis of the position data and practical weighing data. According to the belt shape data processing method and device and storage medium, cooperative relation between automatic zero tracking and belt shape correction in theconveyor belt is made clear, the application effect and reliability of band shape correction can be improved, and thus, the metering performance of weighing is improved.

Description

technical field [0001] The invention relates to a belt shape data processing method and device and a storage medium of a conveyor belt. Background technique [0002] Conveyor belts, especially when applied to belt scales, use both belt shape correction and automatic zero tracking. [0003] The belt shape correction refers to storing the belt shape data of the conveyor belt during belt scale calibration, zero clearing or automatic zero tracking, and subtracting the belt shape data from the weighing data in the application process, thereby eliminating or partially eliminating the The influence of the thickness, hardness, weight, etc. of different positions in the entire belt cycle on the weighing accuracy of the non-integer cycle of the belt scale. [0004] Automatic zero tracking refers to correcting the average zero point data of the belt cycle of the conveyor belt during the operation of the empty scale of the belt scale, thereby eliminating or partially eliminating the we...
