Embodiment Construction

[0028] In order to improve the test accuracy of the pressure-sensitive paper, in the embodiment of the present invention, by applying an impact force to the pressure-sensitive paper, the pressure-sensitive parameters measured by the pressure-sensitive paper and the pressure of the impact force applied to the pressure-sensitive paper are obtained. Sensitive parameters, and then compare the pressure-sensitive parameters measured by the pressure-sensitive paper with the pressure-sensitive parameters of the impact force applied to the pressure-sensitive paper, and then determine the pressure-sensitive parameters according to the comparison results of the pressure-sensitive parameters The precision of the paper does not need to be simulated to calculate the pressure on the pressure-sensitive paper, so the error of the precision test of the pressure-sensitive paper can be reduced, and the accuracy of the precision test of the pressure-sensitive paper can be improved.

Abstract

The invention provides a pressure sensitive paper accuracy test method, device and system. The method comprises the steps that impact force is applied to the pressure sensitive paper through a punch;the pressure parameter measured by the pressure sensitive paper is acquired; the pressure parameter of the impact force applied to the pressure sensitive paper is acquired; the pressure parameter measured by the pressure sensitive paper and the pressure parameter of the impact force applied to the pressure sensitive paper are compared; and the accuracy of the pressure sensitive paper is determinedaccording to the comparison result of the pressure parameter. With application of the scheme, the accuracy of the pressure sensitive paper accuracy test can be enhanced.

Description

technical field [0001] The invention relates to the detection field, in particular to a precision testing method, device and system for pressure-sensitive paper. Background technique [0002] Pressure measurement film, also known as pressure sensitive paper, is a film used to measure pressure, pressure, pressure distribution and pressure balance. When pressure is applied, the microcapsules of the pressure-sensitive paper will rupture, and the chromogenic substance and the color-developing substance will react with each other, so that a red area with a color density that changes with the change of the pressure level appears on the pressure-sensitive paper. Since this process is irreversible, the value recorded at each point on the pressure-sensitive paper is the maximum value on the time history during dynamic measurement. Pressure-sensitive paper is widely used in various fields. For example, in the design and development of electric vehicles, in order to ensure that the fo...
