Referring to fig. 1, fig. 1 is a schematic structural diagram of a weft feeler according to the present invention.
The device includes:

and the digital processing module 3 is connected with the detection module 1 and the analog processing module 2 and is used for performing digital processing on the weft yarn signals to obtain digital weft yarn signals and judging whether the weft yarns reach a preset position according to the first peak value times and the digital weft yarn signals.
The weft detecting device generally comprises a detection module 1 and a processing module, wherein the detection module 1 acquires weft signals, and the detection module 1 judges whether the weft reaches a preset position according to the weft signals.
The applicant considers that the processing modules in the prior art have two processing modes, namely analog processing and digital processing. The analog processing generally processes the weft signals through an analog circuit and determines whether the weft reaches a predetermined position according to the analog processed weft signals, and the digital processing generally processes the weft signals through the processor 32 and determines whether the weft reaches the predetermined position according to the digital processed weft signals. But the aging of the electrical elements of the analog circuit is easy to bring errors, and the vibration of the loom and the long-time oil stain have great influence on the circuit detection accuracy; the digital weft feeling device judges whether the weft yarn normally arrives or not through the digital weft yarn signal, but the digital weft yarn signal is discontinuous, so that the situations of error detection and missed detection are easy to occur in the practical application process.
In this embodiment, the weft feeler includes a detecting module 1, an analog processing module 2 and a digital processing module 3, and the digital processing module 3 can comprehensively determine whether the weft reaches the preset position and whether the analog processing module 2 has a deviation according to the analog weft signal and the digital weft signal.
It should be noted that, the manner of determining whether the weft yarn reaches the preset position according to the first peak number and the digital weft yarn signal is generally three ways in which the analog processing module 2 determines that the weft yarn reaches the preset position and/or the result of the digital weft yarn signal indicates that the weft yarn reaches the preset position, that is, the manner of determining that the weft yarn has reached the preset position is three ways, and the respective manners are that the analog processing module 2 and the result of the digital weft yarn signal both indicate that the weft yarn reaches the preset position, the analog processing module 2 determines that the weft yarn reaches the preset position but the result of the digital weft yarn signal does not indicate that the weft yarn reaches the preset position, and the analog processing module 2 does not determine that the weft yarn reaches the preset position but the result of the digital weft yarn signal indicates that the weft yarn reaches the preset position.
In summary, compared with the mode that whether the weft reaches the preset position is judged only by the digital weft detector or the analog weft detector through the weft signal acquired by the detection module 1, the scheme adopts the analog processing module 2 and the digital processing module 3 to process the weft signal in an analog/digital mode, and judges whether the weft reaches the preset position according to two results of the analog weft signal and the digital weft signal, so that the accuracy and precision of weft detection are improved.
Referring to fig. 2, fig. 2 is a schematic structural view of another weft feeler according to the present invention.

As a preferred embodiment, the digital processing module 3 comprises:
the analog-to-digital conversion module 31 is connected with the amplification module 4 and is used for converting the amplified weft yarn signals into digital weft yarn signals;

the digital processing module 3 is also used for sending a carrier signal to the light-emitting diode after the weft feeler is started.
In consideration of the fact that the detection module 1 in the prior art is always in a power-on state as long as the detection module is started, the service life of the detection module 1 is short, and once the detection module 1 is damaged, the detection module needs to be replaced, so that the production efficiency is affected.
In the present embodiment, a specific implementation of the digital processing module 3 is provided. Specifically, the detection module 1 includes a light emitting diode and a photoelectric receiving tube which are installed at opposite positions, the digital processing module 3 sends a carrier signal to the light emitting diode after the weft feeler is started, and the light emitting diode generates a light pulse signal after receiving the carrier signal sent by the digital processing module 3. When the weft yarn reaches between the light-emitting diode and the photoelectric receiving tube, an interference signal is generated. The photoelectric receiving tube determines the weft yarn signal based on the light pulse signal and the interference signal. Therefore, the detection module 1 is only powered on and used during operation and is not powered on during standby according to the processing condition, so that the service life of the detection module 1 is prolonged, and the detection module is stable and reliable.
Of course, the structure of the detection module 1 is not limited to the above-mentioned manner, and the present application is not limited thereto.
As a preferred embodiment, the digital processing module 3 is further configured to determine that the analog processing module 2 needs to be serviced when the analog weft signal continuously deviates from the normal range within a third preset time.

In this embodiment, the digital processing module 3 determines that the analog processing module 2 needs to be overhauled when the analog weft signal continuously deviates from the normal range within the third preset time.
