Embodiment Construction

[0013] The specific implementation manner of the present invention will be described in further detail below by describing the best embodiment with reference to the accompanying drawings.

[0014] Such as figure 1 As shown, the vibration test is to verify whether the output value of the pressure sensor is stable or whether the fluctuation exceeds the threshold under the premise of a certain pressure and in the face of different vibrations, so as to determine the performance of the sensor. The experimental system includes a vibration test device, a pressure sensor, a data acquisition module, and a transmission module.

[0015] The pressure sensor is set on the vibration test device. The vibration test device drives the sensor to vibrate according to the preset vibration mode. The pressure sensing end of the pressure sensor is in a constant air pressure environment. The data acquisition module collects the pressure sensor in a constant air pressure environment and various vibrat...

Abstract

The invention discloses a sensor vibration experiment data acquisition system. The system comprises a vibration test apparatus and a pressure sensor, the pressure sensor is arranged on the vibration test apparatus, the system also comprises a data acquisition module and a transmission module, the vibration test apparatus drives the sensor to vibrate according to a preset vibration mode, a pressuresensing end portion of the pressure sensor is located in a constant pressure environment, the data acquisition module acquires voltage values output by the pressure sensor in the constant pressure environment and in various vibration modes, and the voltage values are transmitted to a data analysis apparatus for analysis processing through the transmission module. The system is advantageous in that some vibration conditions of the sensor in the practical work are simulated through adjustment of the vibration modes so that the stability and the reliability of the sensor are detected, the quality inspection by manufacturers is facilitated, and data support can be provided for the improvement of products; besides, data can be checked in real time by employing a display screen so that resultsare visual and detection alarm results can be emitted in time through a computer.

Description

technical field [0001] The invention relates to the field of sensor detection, in particular to a sensor vibration experiment data acquisition system. Background technique [0002] With the rapid development of the automobile industry, customers have higher and higher requirements for the intelligence and comfort of automobiles. Correspondingly, the reliability requirements for automotive sensors are becoming more and more stringent. This requires us to conduct environmental tests on the sensor under different conditions, among which the vibration test is one of the more important tests. Through the vibration test, the parameters of the sensor can be obtained to verify the reliability of the sensor. Through the vibration test, the pressure sensor can be better tested. performance. Contents of the invention [0003] The purpose of the present invention is to provide a sensor vibration experiment data acquisition system, which solves the defect of single detection method i...
