Specific embodiment
Core of the invention is to provide a kind of sewing needle away from recognition methods, system, device and sewing machine, any not increasing
It in the case where external cost or device, is not influenced by sewing machine mechanical erection and abrasion, calculated result is more accurate, accuracy of identification
It is higher.
In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with the embodiment of the present invention
In attached drawing, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is
A part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art
Every other embodiment obtained without making creative work, shall fall within the protection scope of the present invention.
Fig. 1 is please referred to, Fig. 1 is a kind of step flow chart of the sewing needle away from recognition methods provided by the present invention, comprising:
Step 1: when cloth blocks the first inductor, obtaining the first Hall edge value；
Step 2: when cloth blocks the second inductor, obtaining the second Hall edge value, wherein the first inductor and second
Inductor is arranged along cloth-feeding direction；
Specifically, the inductor that the first inductor and the second inductor in the present invention all can be carry on overedger,
Without increasing cost and additional device, wherein what the first inductor and the second inductor can be determined according to cloth-feeding direction, with
For C4 overedger, referring to shown in Fig. 2, it is disposed with inductor A, inductor B and inductor C along cloth-feeding direction, then the
One inductor and the second inductor can be followed successively by inductor A and inductor B, and the first inductor and the second inductor can also be according to
Secondary is inductor B and inductor C.When machine stitching, when cloth blocks the first inductor, the first inductor can export the first screening
Signal is kept off, the corresponding Hall edge value of the first inductor is obtained at this time, is denoted as the first Hall edge value H1, while first being incuded
The flag bit F of device11 is set, and is started counting.When cloth blocks the second inductor, the second inductor output second blocks signal,
At this point, obtaining the corresponding Hall edge value of the second inductor, it is denoted as the second Hall edge value H2, while by the mark of the second inductor
Will position F21 is set, specifically, motor Hall is every to change value one number of meter, when motor stops, without counting, and when three inductions
When device is not blocked, removing counting (including F1、F2、H1、H2), pass through the first Hall edge value H1With the second Hall edge value H2
Calculate Hall value Δ H, Δ H=| H2-H1|, when Hall value can be understood as cloth by the first inductor to the second inductor, electricity
The circle number (i.e. needle number) that machine turns over.
Step 3: calculating sewing needle away from, wherein needle gage calculation relational expression according to needle gage calculation relational expression isG is the distance that sewing needle is the first inductor and the second inductor away from, L1, N be motor every revolution suddenly
That edge count value, H1For the first Hall edge value, H2For the second Hall edge value.
Specifically, by taking overseam C4 motor as an example, it is assumed that the distance between the first inductor and the second inductor are L, and should
Motor is four pairs of pole motors, and there are three motor Halls, then the count value of available motor every revolution is 24, therefore, can be led to
It crossesCome calculate the practical sewing needle of the motor away from, the present invention is not influenced by sewing machine mechanical erection and abrasion,
Calculated result is more accurate, and accuracy of identification is higher.
It is understood that every revolution count value may be also not identical for different motors, it is according to practical determination
Can, which is not limited by the present invention.
The present invention provides a kind of sewing needles away from recognition methods, comprising: when cloth blocks the first inductor, obtains first
Hall edge value；When cloth blocks the second inductor, the second Hall edge value is obtained, wherein the first inductor and the second sense
Device is answered to be arranged along cloth-feeding direction；Calculating sewing needle away from, wherein needle gage calculation relational expression according to needle gage calculation relational expression isG is the distance that sewing needle is the first inductor and the second inductor away from, L1, N be motor every revolution suddenly
That edge count value, H1For the first Hall edge value, H2For the second Hall edge value.
As it can be seen that in practical applications, using the solution of the present invention, according between two adjacent inductors actual range and
The circle number (i.e. needle number) that motor turns between two inductors obtained by the first Hall edge value and the second Hall edge value come
Actual sewing needle is calculated away from the case where not increasing any external cost or device, not by sewing machine mechanical erection and mill
The influence of damage, calculated result is more accurate, and accuracy of identification is higher.
On the basis of the above embodiments:
Embodiment as one preferred calculates sewing needle away from later according to needle gage calculation relational expression, and the sewing needle is away from knowledge
Other method further include:
Judge sewing needle away from whether in preset range；
If so, by sewing needle away from be determined as practical sewing needle away from；
If it is not, obtaining the first new Hall edge value and the second new Hall edge value, then will pass through new first suddenly
Your edge value and the second new Hall edge value calculate new sewing needle away from.
Specifically, in order to further increase reliability and accuracy of the invention, the present invention also pre-sets sewing needle
Away from the range that value meets, i.e. preset range, if the sewing needle being calculated away within a preset range, will just be calculated
Sewing needle away from as practical sewing needle away from, if the sewing needle being calculated away from not within a preset range, it is believed that acquisition
The Hall edge value error arrived, then just abandon the secondary calculating, after count value is reset, resurvey the first Hall edge value and
Second Hall edge value calculates new sewing needle away from and verifying new sewing needle away from whether in the preset range, repeat above-mentioned
Step, until obtain sewing needle in the preset range away from, as practical sewing needle away from.
Embodiment as one preferred, by sewing needle away from be determined as practical sewing needle away from process specifically:
Obtain multiple sewing needles in the preset range in preset time period away from and calculate average value, average value is made
For practical sewing needle away from.
Specifically, consider the influence of sampling error, identify practical sewing needle away from when, the present invention will do it multiple meter
It calculates, obtains multiple sewing needles away from obtaining final practical sewing needle away from further by obtained multiple sewing needles away from averaging
Improve accuracy of identification.
Embodiment as one preferred calculates sewing needle away from later according to needle gage calculation relational expression, and the sewing needle is away from knowledge
Other method further include:
By practical sewing needle away from being sent to display screen by serial ports, so as to display screen show practical sewing needle away from.
Specifically, practical sewing needle obtained in above-mentioned steps is sent to display screen, away from by serial communication so as to work
Make personnel by display screen obtain the current practical sewing needle of overedger away from.
Embodiment as one preferred, while obtaining the first Hall edge value, which also wraps away from recognition methods
It includes:
By the mark position 1 of the first inductor；
Correspondingly, the sewing needle is away from recognition methods while obtaining the second Hall edge value further include:
