Problems solved by technology

If a large test air pressure is charged at one time, the product to be tested will be damaged, and the air pressure fluctuations in the test environment will be unstable. Therefore, the above air filling and deflation methods in the air tightness testing process do not meet the high requirements of air tightness testing.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of equipment detection, and in particular, to a method, device, system, electronic device, and medium for controlling inflation and deflation. Background technique [0002] In daily life and industrial production, it is often necessary to perform air tightness testing on various devices such as electronic devices, various gas storage tanks, and pressure tanks. [0003] At present, the pressure drop is usually used to test the air tightness of the cavity. By filling the cavity to be tested with a certain pressure value of test air pressure, and at the same time, the same pressure value is introduced into a standard tank, and it is static for a period of time. After that, the leak detector quantitatively calculates the air leakage of the measured object according to the output change of the differential pressure sensor. [0004] The above method is only suitable for some scenarios with l...
