Abstract

The invention belongs to the electronic weighing field and relates to a new calibration method of an electronic belt scale and supporting devices for implementing the method. According to the new calibration method of the invention, an electronic belt scale calibration algorithm is simplified, so that the electronic belt scale calibration method can be simplified, and therefore, the long-term stable and precise operation of the electronic belt scale can be realized, and the overall level of the electronic belt scale can be improved. According to the electronic belt scale, an electronic belt weighing controller with a one-key calibration function is adopted; and the weighing controller includes a main controller for ensuring high speed and high accuracy of data calculation, a weighing sensor for acquiring output signals, an instrumentation amplifier for amplifying acquired signals, a display screen which queries and modifies the internal parameters of instruments to complete calibrationcontrol, a digital quantity input and output port which can realize the programmability of different kinds of field control logic, an analog quantity input and output port which sets other analog variables, an extended installation slot for installing more functional modules, and one-key calibration system for embedded multitasking real-time operation.

Description

technical field

[0001] The invention relates to the field of electronic weighing, in particular to a novel calibration method and an implementation supporting device for an electronic belt scale. Background technique

[0002] Electronic belt scales have been widely used in industry, mines, docks, grain and other industries. At the beginning of installation and use of electronic belt scales, initial calibration and regular calibration of electronic belt scales are required to ensure good and Long-term stable operation. The traditional electronic belt scale calibration work generally includes parameter acquisition, zero point calibration and interval calibration, and the setting of the working parameters of the belt scale, etc., but in actual use, due to the many parameters of the electronic belt scale, the calibration work is more complicated Moreover, the workload is relatively large, and in a large number of occasions, it depends on the experience and proficiency of the op...
