Embodiment Construction

[0048] This implementation method is for better understanding of the present invention, and is not used to limit the conditions of the present invention.

[0049] Belt scale load cell calibration method, including:

[0050] 1. The accumulator calculates the cumulative amount and total cumulative amount of a single load cell under different working conditions when the weighing system is in good condition, and calculates the logarithmic value of the quotient of the cumulative amount of a single load cell and the total cumulative amount respectively. In the section, a set of logarithmic curves with zero as the base point is obtained, and the maximum and minimum values ​​of the curves are corrected. The corrected interval with zero as the base point is used as the standard area for comparison, and records of various working conditions Standard area and total cumulative amount, where: the cumulative amount includes the cumulative amount in the state of no-load, chain code and weigh...

Abstract

The invention discloses a calibrating method of a weighing sensor of a belt scale, belonging to the technical field of dynamic weighing. The calibrating method is characterized by comprising the following steps of: obtaining a comparative standard value range by collecting actual weighing values, obtaining a real-time zero value by using logarithm values of different combinations of accumulative amounts to be compared with the standard value, automatically tracking and judging an error tendency of the accumulative amounts of the weighing sensor, further diagnosing the position and system where the error is; and calibrating the weighing sensor according to the error curve. The calibrating method has the advantages: structurally, a mature general technology is adopted, the calibrating method can be used for timely, accurately and reliably judging errors, is not only convenient to check and but also has the function of fault prevention so that traditional breakdown maintenance turns into beforehand maintenance, thereby substantially reducing the failure rate.

Description

technical field [0001] The invention relates to a dynamic weighing technology, in particular to a method for calibrating a weighing sensor of a belt scale. Background technique [0002] At present, electronic belt scales have been widely used as weighing equipment for belt conveyors to convey materials, but in the actual application process, there are many factors that affect the weighing accuracy, and inaccurate measurement often occurs, causing economic losses, especially as a batching measurement. directly affect product quality. Since the factors that cause weighing accuracy errors are affected by sensor performance, belt tension changes, bearing mechanisms and the environment, and the load cell is the most important weighing component, after the belt scale is installed and running, the load cell must be checked. The current calibration method mainly relies on the experience and proficiency of the commissioning personnel to debug the total cumulative amount, especially ...
