Detecting system for rapid sealing of concentration sensor and method thereof

Abstract

The invention discloses a detecting system for rapid sealing of a concentration sensor and a method thereof. The detecting system comprises a prism head shell of the concentration sensor to be detected, a measurement bracket, a camera, an atmospheric pressure cavity, an automatic air feeding pressurizing device, an air cylinder and a main controller; the camera, the air cylinder and the automaticair feeding pressurizing device are all electrically connected with the main controller; the method of the system comprises the step that the main controller performs data analysis and comparison on atest image which is shot and uploaded by the camera and an initial image, and judges whether the sealing of the concentration sensor is qualified or not according to the data analysis and comparisonresult; all test data are recorded automatically; the automation degree is high; the manual cost is reduced; meanwhile, the test time is shortened; the production efficiency is improved; and the production potential safety hazard is reduced.

Description

technical field [0001] The invention relates to the field of sensor detection equipment, in particular to a rapid sealing detection system for a concentration sensor and a method thereof. Background technique [0002] The current pressure tolerance test adopts manual testing. The specific method of manual testing is: the worker tightens the screws, clamps the prism lens housing and the air pressure chamber, and then manually adjusts the pressure valve to pressurize, observe the test pressure resistance, and wait until the test is completed. Manually exhaust, disassemble, and replace with a new prism lens housing to continue testing. [0003] The above-mentioned manual testing method has the following defects: manual testing is uncertain, and visual fatigue is prone to occur during repeated repetitions. While affecting the efficiency of pressure measurement, it is difficult to ensure the qualification of the product; at the same time, manual testing takes a long time , high ...

[0003] The manual testing method mentioned above has the following defects: manual testing is uncertain, and visual fatigue is prone to occur during repeated repetitions. While affecting the efficiency of pressure measurement, it is difficult to ensure the qualification of the product; at the same time, manual testing takes a long time , high labor intensity, low production efficiency, and if the sealing interface leaks during pressurization and pressure relief operations, there will be safety hazards

[0004] Invention patent: (Publication No. CN105389814A, name: a bubble detection method for air tightness experiment) describes a bubble detection method, using the camera to capture the image frame and the background frame to perform differential calculation to obtain the frame difference image, and then perform Contour extraction, and then use the centroid distance method difference analysis to obtain the contour centroid, and then calculate the approximate radius of the contour to obtain the average radius of the bubble and calculate the roundness error value, and then compare it with the reference value to determine whether there is a bubble. The calculation process of this method is complicated and tedious. And it is prone to errors. When the bubbles gather together to form a bubble string, this method is likely to misjudge
