  • Patent number: 11781974
    Abstract: A method for detecting gas concentration in a glass bottle with dynamical threshold adjustment is provided includes acquiring second harmonic peaks P0, Pa, PX in the glass bottle, calculating absolute values of the differences between P0 and Pa, as well as between P0 and PX, and performing quality inspection on a glass bottle to be detected. The performing includes collecting the second harmonic peaks for the glass bottle to be detected, calculating a mean PL of elements in the current queue L, updating the second harmonic peak Pa and the second harmonic peak PX, collecting second harmonic peaks for a current glass bottle to be detected, and determining whether the current glass bottle to be detected is an acceptable medicinal bottle based on the updated data and the collected second harmonic peaks.

  • Patent number: 11650408
    Abstract: A true-seeing infrared industrial endoscope endoscope includes an external shell protective unit including a housing and an electrical appliance component box connected to a rear end of the housing. A cavity of the housing is provided with a dual capturing-imaging unit including at least two capturing-imaging subunits. Each of the capturing-imaging subunits includes a light splitter, an image capturing lens, an infrared imaging tube, and a visible light imaging tube. The electrical appliance component box is provided with a communication module and a power supply electrically connected to the dual capturing-imaging unit and the communication module. The communication module is communicatively connected to the dual capturing-imaging unit and an upper computer via a communication bus, and the power supply is electrically connected to the dual capturing-imaging unit via a power bus.

  • Patent number: 11605169
    Abstract: A method for detecting a flow velocity of a high-temperature molten fluid can include: collecting a video stream of a high-temperature high-velocity molten fluid, decomposing the video stream into a frame image sequence sorted by time, and extracting a molten fluid Region Of Interest (ROI) from the frame image sequence, extracting a molten fluid outline of the molten fluid ROI, and extracting a characteristic block of the molten fluid outline, and obtaining the flow velocity of the molten fluid based on the characteristic block. A flow velocity detection accuracy can be improved for a molten fluid with a high temperature, a high velocity and a high glossiness.

  • Publication number: 20220107264
    Abstract: A method for detecting gas concentration in a glass bottle: firstly, second harmonic peaks P0, Pa, PX of the glass bottle are obtained under the same detection environment 0%, an acceptable concentration threshold a % and a reference concentration auxiliary threshold X %; then absolute values of the differences between P0 and Pa, as well as between P0 and PX, so as to obtain Da, Dx, and to write P0 into a queue with a length of M; next, quality inspection is performed on each glass bottle to be detected by: collecting the second harmonic peak PN of the glass bottle and determining if PN?Pa is true; wherein if true, it is determined whether PN?PX is true, and, if true, the second harmonic peak of the medicinal bottle is written into the queue, the queue is averaged to obtain PL, update is performed Pa=PL+Da, PX=PL+DxPa=PL+Da, PX+PL+Da, which is used for the detection of the next medicine bottle after updating.
