Embodiment Construction

[0017] A kind of weigh rechecking method with error compensation provided by the present invention, it comprises the following steps:

[0018] Step 1: Store the target value of the material quality set externally in the control system;

[0019] Step 2: The control system inputs the given target value into the PLC, and the PLC gives the feeding signal to make the feeding mechanism start feeding, at this time, the electric valve and the vibration motor are in the closed state; obtain the first weighing signal sent by the first weighing unit F1=nqLgcosθ+2TKD1 / L; among them, n is the number of weighing roller groups, q is the linear density of weighing load, L is the distance between rollers, g is the acceleration of gravity, θ is the inclination angle of the conveyor, T is the belt tension, K is Belt rigidity coefficient, D1 is the non-alignment degree of the weighing idler of the first weighing unit;

[0020] Step 3: The material is accumulated in the hopper, and the pressure g...

Abstract

The invention relates to the field of electronic weighing, and particularly relates to a weighing reinspection method having error compensation. The weighing reinspection method having error compensation comprises six steps and performs calculation and compensation by using three formulas. According to the weighing reinspection method having error compensation, the nonlinear influence of erratic result caused in weighing can be eliminated, and the weighing accuracy and durability and repeatability can be enhanced.

Description

technical field [0001] The invention relates to the field of electronic weighing, and more specifically relates to a weighing repeat checking method with error compensation. Background technique [0002] Weighing equipment usually refers to the weighing equipment for large objects used in industry or trade. It refers to the supporting use of modern electronic technologies such as program control, group control, teleprinting records, and screen display, which will make the weighing equipment function Complete and more efficient. Weighing equipment is mainly composed of three parts: load-bearing system (such as weighing pan, scale body), force transmission conversion system (such as lever force transmission system, sensor) and display system (such as dial, electronic display instrument). In today's combination of weighing, production and sales, weighing equipment has received great attention, and the demand for weighing equipment is also increasing. [0003] Traditional weig...
