In above-mentioned sewing machine wire break detection method, in step B, if image does not change in T1 time ranges, Output broken string result.
When detecting sewing threads and whether breaking, preset time T 1 in systems.When broken string, it is normally at camera Sewing threads transfixion, therefore, in the range of time T1, if constant always with line image, judge sewing threads send out Raw broken string situation, system output broken string result.
In above-mentioned sewing machine wire break detection method, in step B, if image changes in T2 time ranges, Output line length result.
This method also can detect that with line length, i.e., carries out comparing calculation, output line length result to multiple image.
In above-mentioned sewing machine wire break detection method, in step B, if image does not change in T3 time ranges, The image that erasing part has stored.
In order to avoid unwanted picture takes storage area, therefore, T3 is preset in systems, is deleted image has partly been stored Remove, ensure that system there are enough storage areas to store new view data.
The invention also provides a kind of sewing machine safe to use, its technical scheme are as follows:
Sewing machine, it is characterised in that including above-mentioned wire-off detection device for sewing machine.
In this sewing machine, above-mentioned wire-off detection device for sewing machine has been used so that using more convenient.

Embodiment
As shown in Figure 1 to Figure 3, this wire-off detection device for sewing machine includes support 1.Support 1 includes base 12 and is fixed on Lid 13 on base 12.Support 1 includes base 12 and lid 13, and circuit board 2 is arranged on base 12.Support 1 is set to include Base 12 and lid 13 so that the sealing of the present apparatus is preferable, so that the imaging effect of camera 3 is more preferable, improves the present apparatus Detection results.
Specifically, base 12 includes first base 16 and second base 17, circuit board 2 is arranged on first base 16 and second Between base 17.Circuit board 2 is provided with the camera 3 relative with crossing line mouth 11.
Optical lens 4 is additionally provided with support 1, optical lens 4 includes imaging section 41 and assisted parts 42.Imaging section 41, which is located at, to be taken the photograph As first 3 and between crossing line mouth 11, circuit board 2 is provided with light-emitting component 5, assisted parts 42 be located at light-emitting component 5 and mistake line mouth 11 it Between.The setting of the imaging section 41 of optical lens 4 so that camera 3 is to more preferable with the shooting effect of line so that the detection effect of the present apparatus Fruit is more preferable.In addition, light is radiated on sewing threads by assisted parts 42, improves the shooting effect of camera 3 by light-emitting component 5 Fruit so that the Detection results of the present apparatus are more preferable.
Have on support 1 and cross line mouth 11 for what line passed through, specifically, support 1 is provided with two line crossing brackets 14, line crossing bracket 14 It is provided with threading opening 15.Camera 3 is between two line crossing brackets 14.In use, sewing threads are through two line crossing brackets 14 Threading opening 15, and by crossing line mouth 11 on support 1.
During the use of this broken thread detector, sewing threads are crossed into line mouth 11, sewing process through on support 1 In, the camera 3 on circuit board 2 is shot to sewing threads, judges whether to break.Due in the present apparatus, passing through shooting First 3 realize to realize whether judge broken string, rather than by short-circuit conductivity principle, and therefore, the present apparatus uses safer.Separately Outside, as needed, the present apparatus can also shoot the pattern of multiframe sewing threads by camera 3, handled by system, calculate use Line length.
The invention also provides a kind of sewing machine wire break detection method safe to use, comprise the following steps:
A, with 3 line for shooting of camera, image is obtained;
B, system process images, testing result is exported.
In step B, if image does not change in T1 time ranges, output broken string result.It is in detection sewing threads During no broken string, preset time T 1 in systems.When broken string, the sewing threads transfixion that is normally at camera 3, because This, in the range of time T1, if constant always with line image, judges that broken string situation occurs for sewing threads, system output is disconnected Knot fruit.
In step B, if image changes in T2 time ranges, output line length result.This method can also be examined Measure and use line length, i.e., comparing calculation, output line length result are carried out to multiple image.
In step B, if image does not change in T3 time ranges, the image that part has stored is wiped.In order to avoid Unwanted picture takes storage area, therefore, presets T3 in systems, will partly store image-erasing, ensured that system has enough Storage area stores new view data.The general value for setting T1 is more than T3 value.
In this sewing machine wire break detection method, due to by the detection of camera 3 line situation, therefore using more pacifying Entirely.Multiple image is analyzed system, exports testing result.
The invention also provides a kind of sewing machine safe to use, including above-mentioned wire-off detection device for sewing machine.
In this sewing machine, above-mentioned wire-off detection device for sewing machine has been used so that using more convenient.
