The alarm module of this embodiment includes audible-visual annunciator 14, and audible-visual annunciator 14 fixes the up end at second backup pad 5, and audible-visual annunciator 14 is used for selecting to carry out alarm information show.

The working principle is as follows: this tension adjustable sewing machine stay wire mechanism is before using, at first, twist positioning bolt, separate first supporting seat 2 and second supporting seat 4 and make first backup pad 3 and second backup pad 5 part enough distance, then, install bobbin 605 of bobbin subassembly 6, move down second supporting seat 4 again, it is close to first backup pad 3 to drive second backup pad 5, and make the square shaft 702 of line ball power component 7 insert in the square hole of being connected 604 of bobbin subassembly 6 on the second backup pad 5, finally, pass fixed wire ring 8 with the one end of bobbin 605 upper thread, first activity wire ring 9, second activity wire ring 10 and sleeve 12 can begin to use, and fixed wire ring 8, first activity wire ring 9, the cooperation of second activity wire ring 10 is used and can be adjusted the tension of line, specifically do: the spacing of the first movable conductor ring 9 and the second movable conductor ring 10 on the second support plate 5 and the first support plate 3, respectively, is changed.

Subsequently, the motor 701 is started, the motor 701 drives the square shaft 702 to rotate, the square shaft 702 drives the rotating shaft 602 to rotate, the rotating shaft 602 provides a rotating force for the wire barrel 605, so that the wire can be conveniently led out, the wire is sequentially led into the sleeve 12 from the fixed wire ring 8, the first movable wire ring 9 and the second movable wire ring 10, and is led out from the sleeve 12 to the wire using part, and in the process, the monitoring system monitors the tension and the diameter of the wire, specifically: the image receiving module receives the images shot by the micro camera 16 and the images shot by the camera 13 and transmits the received images to the image processing module; the image processing module receives the image transmitted by the image receiving module, generates processed image information, the monitoring model receives the image information, and monitors, analyzes and calculates the line tension and the diameter in real time, wherein the processing is carried out according to the line tension monitoring model and the line diameter monitoring model, the result is finally output to the alarm module, and the alarm module selectively executes alarm processing according to the result. The method for constructing and processing the line tension monitoring model comprises the following steps: s1: cutting the received image of the camera 13, and reserving the image in the second movable wire loop 10; s2: dividing the processed image into three pictures;

s3: the divided pictures are labeled as A1-A3 according to the sequence of 1-3; s4: identifying the number of lines in the pictures with different labels by an image identification technology; s5: the number of lines in a1 is labeled B1, the number of lines in a2 is labeled B2, and the number of lines in A3 is labeled B3; s6: if B3 is more than or equal to 1 and B1 is equal to B2 is equal to 0, outputting a monitoring result that the tension is abnormal; s7: if B1 is more than or equal to 1 and B2 is equal to B3 is equal to 0, outputting a monitoring result that the tension is normal; s8: if B2 is more than or equal to 1 and B3 is 0, the tension is loose as the output monitoring result. The construction processing method of the wire diameter monitoring model comprises the following steps: the method comprises the following steps: identifying the width of a central line of an image shot by the miniature camera 16 through an image identification technology; step two: marking the width of the previously identified line as Pi, i-1 … … n; step three: marking the width of the line identified in real time as Pz; step four: matching Pz with Pi, and if the Pz is matched with any Pi, outputting a monitoring result that the wire diameter is normal; if Pz does not match any Pi, the monitoring result is output as the abnormal diameter of the wire, and the abnormal diameter result is classified. The specific grading process of the diameter abnormal result is as follows: 1): the difference between Pz and any Pi is denoted as Ki ═ Pz-Pi |, i ═ 1 … … n; 2): if Ki is between 0 and 0.1mm, outputting a monitoring result that the first-stage is abnormal; 3): if Ki is larger than 0.1mm and smaller than 0.3mm, outputting a monitoring result that the second-stage is abnormal; 4): if Ki is more than 0.3mm, outputting a monitoring result with three-level abnormality.

The alarm module receives the monitoring result and gives an alarm when the monitoring result is abnormal, wherein the alarm module is an audible and visual alarm 14, the sound and the light of the audible and visual alarm 14 are separately controlled, and if the tension monitoring model outputs the monitoring result that the tension is abnormal, the audible and visual alarm 14 lights a red light. If the tension monitoring model outputs a monitoring result that the tension is normal, the audible and visual alarm 14 lights up a green light. If the tension monitoring model outputs a monitoring result that the tension is loose, the audible and visual alarm 14 lights a yellow light. If the monitoring result output by the wire diameter monitoring model is that the wire diameter is normal, the audible and visual alarm 14 does not make a sound. If the output monitoring result is that the line diameter is abnormal, the audible and visual alarm 14 makes a sound and makes sounds of different decibels according to the classification of the abnormal diameter result, wherein the alarm sound corresponding to the three-level abnormality is the largest, and the alarm sound corresponding to the one-level abnormality is the smallest.

The above description is only for the preferred embodiment of the present application, but the scope of the present application is not limited thereto, and any person skilled in the art can substitute or change the technical solution and its concept of the present application within the technical scope disclosed in the present application, and shall be covered by the scope of the present application.
