An online real-time calculation and evaluation method for electronic belt scales

Abstract

The invention discloses an online real-time calculation and evaluation method of an electronic belt scale, which uses the electronic belt scale's material signal as a trigger condition to collect the weight collection value, speed collection value, instantaneous flow collection value and cumulative weight collection value output by the electronic belt scale. And calculate the instantaneous flow calculation value and the cumulative weight calculation value; calculate the ratio of the collection points where the instantaneous flow collection value is within the upper and lower limits of the instantaneous flow calculation value to the total collection points, and the cumulative weight collection value is within the upper and lower limits of the cumulative weight calculation value The ratio of the collection points to the total collection points is used to obtain the pass rate of the instantaneous flow collection value and the cumulative weight collection value. The invention is a method for judging the matching between the instantaneous flow rate and the cumulative weight of the electronic belt scale, which realizes the real-time monitoring of the weighing accuracy of the electronic belt scale, estimates the risk of weighing errors, and can timely alarm and shut down through real-time evaluation, reducing the quality of production materials In the case of damage, the process monitoring of the electronic belt scale is greatly enhanced.

Description

technical field [0001] The invention relates to the technical field of electronic belt scales, in particular to an online real-time calculation and evaluation method for electronic belt scales. Background technique [0002] Electronic belt scales are important equipment in the production line of the manufacturing industry to achieve accurate measurement of moving materials. In the 03 edition of the cigarette process specification, the stability of the material flow rate (instantaneous weight) in the processing process is used as an index to measure the processing capacity, and all manufacturers are working hard to improve this index. The stability of the material flow in the process is guaranteed by the constant-flow electronic belt scale, so each electronic belt scale manufacturer has thought of many ways to stabilize the material flow, such as mechanically controlling the height of the material on the electronic belt scale, so that through The height of the material in th...
