Car roof static pressure test displacement sensor detection system, detection method, terminal and application

Abstract

The invention discloses a car roof static pressure test displacement sensor detection system, a detection method, a terminal and application, which relate to the technical field of car roof static pressure tests. The car roof static pressure test displacement sensor detection system comprises a displacement sensor used for acquiring displacement data generated by a car body at different heights and angles in a car roof static pressure test, a data collector comparing and analyzing the obtained displacement data with a preset threshold value and performing early warning prompt on the displacement data exceeding a certain data range, and a data collection and processing system carrying out display interface visualization presentation on the early warning prompt information. By means of the four plane grooves of the aluminum profile framework, the displacement sensor can be installed and fixed in different directions. Operation is simple and easy, and manufacturing raw materials are low in cost. Even one person can complete the whole operation easily, and personnel are saved. A lot of working hours are saved, and time and labor are saved.

Description

technical field [0001] The invention belongs to the technical field of roof static pressure test, and in particular relates to a displacement sensor detection system, detection method, terminal and application of vehicle roof static pressure test. Background technique [0002] As an independent auto part, the car roof needs to be tested after production to ensure that it matches the car body. In the process of testing, supports are often needed. In the existing technology, most of the car roof is directly Placed on the testing table for testing. In order to realize the detection, the prior art only sticks tape on the bottom of the car body before the experiment, and measures the size of the car body intruded into the tape after the experiment to obtain the displacement of the car body. The measurement accuracy of this method is not high. [0003] Furthermore, during the inspection process of the car, it is necessary to use the roof quality inspection device to inspect the ...

AI Technical Summary

Problems solved by technology

[0005] (1) In the existing technology, the height and angle of the displacement sensor cannot be adjusted according to the actual situation, resulting in low measurement accuracy of the displacement of the vehicle body

Accurate measurement of displacement and real-time data collection during the body test cannot be guaranteed

[0006] (2) In the measurement of the experimental displacement of the car body in the prior art, the operation is cumbersome, the cost of raw materials is high, and the measurement efficiency is low

Due to the heavy weight of the iron block, it is not easy to move and adjust, so the work is difficult

[0009] (2) The displacement sensor is small in size and cannot be firmly fixed on the iron block

[0010] (3) Use tape to detect displacement, which cannot guarantee the accuracy of measurement
