The present invention is accurately positioned and detection method is as follows：
I.e. head from initial position (at this time the 6 position p0)s of inductor, tenon 10 is put down when close to required yarn mouth 3,
It is run along 16 track of goat's horn of yarn mouth 3, (inductor 6 at this time when inductor 6 passes through from 3 right side magnetic field induction source 5 of yarn mouth
Set p1), inductor 6 can obtain yarn mouth precise physical location：
Px1=p1+s
For p1=since p0, head 2 runs passed by needle number (distance)
Wherein s refers to distance of the magnetic field induction source 5 to yarn mouth center line
Under the drive of tenon 10, yarn mouth 3 continues to move ahead, the weaving operation completed required for the dyed yarn of this kind of color is completed
When, computer instruction, tenon 10 exits, and yarn mouth 3 is stopped, and (3 position px2 of yarn mouth is accurate stand at this time) then incudes
Device 6, by magnetic field induction source 5 on the goat's horn of the other side, obtains location information p3 at this time in company with tenon 10
Px2=p3-s
For p3=since p0, head 2 runs passed by needle number (distance)
Wherein s refers to distance of the magnetic field induction source 5 to yarn mouth center line
From the foregoing, it will be observed that because can sense the relevant parameter in startup and stopping of yarn mouth 3, and can be obtained by calculating
3 exact position numerical value of yarn mouth.
Yarn mouth can accurately be positioned using the present invention.Such as above-mentioned positions px2, while being also next weaving cycle
When start bit.The data measured when equally can be with the starting in next period are compared with the data that last time terminates, and with
This analogizes, and can accomplish that total travel compares.
Above-described embodiment is the description of the invention, is not limitation of the invention, it is any to simple transformation of the present invention after
Scheme all belong to the scope of protection of the present invention.
