specific Embodiment 1

[0044] Such as figure 1 As shown, the instrument calibration system is designed to quickly build an uncertainty model dedicated to instrument calibration, and to quickly evaluate the uncertainty of the instrument calibration while completing normal instrument calibration operations, including A storage unit 100 and a processing unit 200 .

[0045] The storage unit is not limited to a certain physical carrier. Specifically, the storage unit can be a hard disk, memory, USB flash drive or other feasible storage media configured on the local computer, or a network server or a network platform with storage functions. As far as this specific embodiment is concerned, various storage technical means that have data storage capabilities and support data retrieval and management when needed are all feasible.

[0046] The processing unit is not limited to a certain physical carrier. Specifically, the processing unit can be configured in the processor, processing module or other feasible ...

specific Embodiment 2

[0092] Such as figure 2 As shown, the uncertainty assessment component model (hereinafter referred to as the assessment component model, correspondingly, the uncertainty assessment component is referred to as the assessment component) is established in the system.

[0093] The evaluation component model includes five mandatory items including component name, sensitivity, distribution type, calculation parameter and calculation formula, and five optional items including component number, component type, instrument type and applicable scope; it can be set according to the evaluation component model. Generate specific rating components.

[0094] Specifically, the component name is used to distinguish different specific assessment components imported into the system based on the assessment component model.

[0095] Specifically, sensitivity is used to describe the impact of specific evaluation components on the total standard uncertainty. In this specific embodiment, the optimiz...

specific Embodiment 3

[0191] Based on the technical solution of the second embodiment, this embodiment provides a specific solution for establishing the uncertainty assessment database.

[0192] For example, the establishment of the pressure repeatability uncertainty assessment component (hereinafter referred to as the pressure repeatability component), differs from the assessment component model in the aforementioned specific embodiment 2 in that the pressure repeatability component is established based on the call and setting of the assessment component model The specific assessment component, the pressure repeatability component can be used for the uncertainty calculation / assessment of a specific pressure calibration, and the assessment component model is used to generate different specific assessment components according to different specific settings.

[0193] According to the evaluation component model, the input component name is "pressure repeatability component", the default (input) sensitivi...

Description

technical field [0001] The invention relates to the technical field of measurement and detection, in particular, an instrument calibration system that supports rapid modeling and evaluation of the uncertainty of instrument calibration. Background technique [0002] When calibrating / verifying industrial instruments such as pressure, temperature, humidity, etc., since this calibration / verifying itself is a kind of measurement behavior, it is necessary to introduce measurement uncertainty evaluation. [0003] Measurement uncertainty, referred to as uncertainty, refers to the degree of uncertainty about the measured value due to the existence of measurement errors, and in turn, it also indicates the degree of reliability of the result. It is an indicator of the quality of measurement results (such as calibration data), generally speaking, the smaller the uncertainty, the closer the result is to the true value of the measurand, the higher the quality of the measurement results, t...
