Embodiment Construction

[0026] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0027] figure 1 It is a flow chart of the calibration method of the weight sensor of the electronic scale according to the present invention.

[0028] In step S101, the functional relationship of the weight sensor is stored in advance.

[0029] Wherein, the functional relationship is the slope of a curve used to identify the linearity of the electronic scale, and under the curve used to identify the linearity of the electronic scale, different output values ​​correspond to different linearities.

[0030] Preferably, the curve indicating the linearity of the electronic scale is an arc.

Abstract

The invention discloses an electronic balance and a correction method and a device of a weight sensor of the electronic balance. The method comprises the following steps of: acquiring current output values of the weight sensor; matching corresponding functional relationships with the output values according to the output values, wherein the functional relationships are used for identifying gradients of curves of electronic balance linearity, and under the curves used for identifying the electronic balance linearity, different output values correspond to different linearities; acquiring corresponding correction values according to the matched functional relationships; and performing correction on the current output values of the weight sensor according to acquired correction values. By means of the electronic balance and correction method and the device of the weight sensor of the electronic balance, line segments used for identifying electronic balance linearity in the prior art is changed into the curves, and by means of the curves, different output values correspond to different linearities. By means of the electronic balance and correction method and the device of the weight sensor of the electronic balance, output values can be more close to actual weights, elimination rate of weight sensors with low linearity is reduced, and output accuracy of weight sensors is further improved.

Description

technical field [0001] The invention belongs to the field of measurement, and in particular relates to a calibration method and device for an electronic scale and a weight sensor thereof. Background technique [0002] The current technical electronic scales are all produced based on the assumption that the weight sensor is linear. Therefore, the linearity of the weight sensor is a very critical indicator, which directly affects whether the measurement of the electronic scale is qualified. However, the weight sensor whose linearity does not meet the standard can only be downgraded for use or scrapped, which causes a huge waste of the cost of the electronic scale. [0003] How to reduce the elimination rate of weight sensors with low linearity and improve the output accuracy of weight sensors is one of the research directions in the field of metrology. Contents of the invention [0004] The object of the present invention is to provide a calibration method and device for an...
