The invention is realized by adopting the following technical scheme:
1. an air tightness test curve management and control algorithm comprises the following steps:
1) the airtightness test comprises four stages: an inflation stage, a pressure stabilizing stage, a testing stage and an exhaust stage;
2) observing whether the test sample is good or not according to a curve generated by the change of the gas in the four stages;
3) A curve used as a test standard and a range can be set to judge the tested curve;
4) through three points (e.g.: the boundary point from the inflation stage to the pressure stabilization stage, the boundary point from the pressure stabilization stage to the test stage, the boundary point from the test stage to the exhaust stage, and the like) or a plurality of points, and whether the sample is leaked is judged;
5) performing air tightness test by using a plurality of good products or one good product, wherein each sample can obtain a curve, and the good product curves are all in the range of a standard curve;
2. the air tightness test result is judged by the air tightness test curve management and control algorithm, and the time change in the test process can be directly reflected according to the generated curve so as to judge whether the air tightness of the sample is excellent or not; the leakage range and the leakage trend can be visually judged according to the positions of the points.
The beneficial effects of the invention are as follows:
the air tightness test curve management and control algorithm keeps the function of displaying the original measurement and calculation result, solves the problem that the data displayed in the original measurement and calculation result is too complicated and complicated, and enables the measured data to be clear at a glance. Meanwhile, the operation steps of the instrument are simplified, the convenience is brought to testers to understand and operate by hands, and the time efficiency of the air tightness test process is improved.
