Method and system for quickly analyzing automobile DTS measurement data

Abstract

The invention provides a method and system for quickly analyzing automobile DTS measurement data. The method for quickly analyzing the automobile DTS measurement data comprises the steps of establishing partitioning rules according to coordinates, and setting unique area codes; structuring the DTS measurement database of the whole vehicle according to rules, and automatically mapping the DTS measurement value to the DTS measurement database of the whole vehicle; performing grouping statistics according to the area numbers in the DTS measuring point numbers, and visualizing the statistics result; performing correlation presetting on the DTS section number and the part number through the influence factor, mapping the part measurement report to a whole vehicle DTS database according to part number information in the structured part measurement report number, and feeding back an analysis result according to the part measurement report of the related part number in the database during out-of-tolerance analysis; according to the method and the system for quickly analyzing the DTS measurement data of the automobile, the rectification priority can be quickly determined, the rectification efficiency is improved, and the DTS out-of-tolerance reason can be quickly analyzed to formulate a rectification strategy.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a method and system for rapidly analyzing automobile DTS measurement data. Background technique [0002] DTS=Design Tolerance Specification, that is, design tolerance specification [0003] With the increasingly intensified competition in the automotive industry, and the clearance and surface difference of the vehicle is a direct reflection of the process capability of the OEM, users have also put forward higher requirements for the appearance quality of the vehicle, and the clearance and surface difference have gradually become one of the focuses of customers. , affect the customer's car purchase and car experience, so we must continue to pay attention to the process of achieving the design and size specifications of the whole vehicle with both quality and efficiency, and it is also a necessary condition for maintaining market competitiveness. [0004] The measurement and s...

Problems solved by technology

[0004] The measurement and statistics of vehicle clearance and surface difference in the prior art often measure and statistic the overall vehicle or the overall exterior or the overall interior, simply process the measurement data, and feed back to the engineer in the form of charts and numbers. Such data statistics It is often inconsistent with the customer's perception of the gap and surface difference of the appearance of the vehicle, and the engineer cannot quickly capture which specific area is in a poor state and needs to be rectified first, and cannot use this set of data to effectively improve the pass rate of the gap and surface difference; moreover, now In the existing technology, the qualified status of DTS measurement is not related to the measurement data of related parts, and the efficiency of DTS out-of-tolerance analysis is low;

[0005] The measurement and statistics of vehicle clearance and surface difference in the prior art often measure and statistic the overall vehicle or the overall exterior or the overall interior, simply process the measurement data, and feed back to the engineer in the form of charts and numbers, etc., to solve practical problems At present, there are the following deficiencies: 1. The existing technology and method cannot carry out zoning statistics according to different perspectives of the vehicle, cannot quickly identify which area of ​​the vehicle is more out of tolerance, cannot determine the priority of rectification, and the rectification efficiency is relatively low; 2. The current There are technologies and methods, and it is not possible to conduct zoning statistics according to the level of customer perception. The data statistics of the pass rate of clearance and surface difference are often inconsistent with the customer's perception of the vehicle, and the priority of rectification cannot be determined, and the rectification efficiency is relatively low; 3. Existing technology And methods, it is impossible to visualize and compare the information such as the pass rate and achievement status of the whole vehicle and division at different stages of the same model at the same time, and it is impossible to visualize the information such as the pass rate and achievement status of the whole vehicle and division at different stages of different models at the same time. It is conducive to promoting the achievement and improvement of the dimensional pass rate; 4. Existing technologies and methods cannot correlate the measurement data of the clearance and surface difference with the measurement data of related parts, which is not conducive to promoting the achievement and improvement of the dimensional pass rate;
