Abstract

The invention discloses an airtightness detection system through differential pressure. The system includes a central processing module, a data acquisition module, a signal conditioning module, a solenoid valve control module, an acousto-optic alarm module, a power supply module and a man-machine interaction module. The data acquisition module sends an acquired signal that has been processed by the signal conditioning module to the central processing module for processing. The solenoid valve control module controls a solenoid valve to be automatically on and off through an instruction of the central processing module. The acousto-optic alarm module is connected to the central processing module. The power supply module provides power to the whole system. The man-machine interaction module controls the input and the output of the system. The system is easy to operate, exhibits good stability and high precision, enables the detection speed to be increased through adoption of an ARM hardware platform, and also meets the requirement of portability.

Description

technical field [0001] The invention relates to the technical field of detection, in particular to a differential pressure air tightness detection system. Background technique [0002] The continuous progress of modern production has put forward higher and higher requirements for detection methods. As a kind of detection method, air tightness detection plays an increasingly important role in ensuring product quality. For products that strictly require tightness, if leakage occurs during use and the leakage exceeds the allowable range, it will directly affect the reliability and economy of the product, and may also cause serious consequences such as fire, explosion, and harmful gas overflow. , causing irreparable losses. How to quickly and accurately detect the amount of leakage has always been a concern of relevant enterprises and an urgent problem to be solved. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a...
