Abstract
A welding system is provided. The welding system includes a low power transceiver configured to be coupled to a weld cable. The low power transceiver includes a low power transmitter, a low power receiver, and a first processor. The low power receiver is configured to transmit one or more unmodulated tones through the weld cable to a welding power supply. The low power receiver is configured to receive the one or more unmodulated tones through the weld cable from the welding power supply. The first processor is configured to determine one or more channel equalization filter coefficients related to the weld cable corresponding to a distortive characteristic of the weld cable.
Claims20
A welding system, comprising:
- a welding device comprising a low power transceiver configured to be coupled to a weld cable, wherein the low power transceiver comprises:
- a low power transmitter configured to transmit one or more unmodulated tones through the weld cable to a welding power supply;
- a low power receiver configured to receive the one or more unmodulated tones through the weld cable from the welding power supply;
- and
- a first processor configured to determine one or more channel equalization filter coefficients related to the weld cable corresponding to a distortive characteristic of the weld cable,
- wherein a second processor is configured to transmit and receive data related to a welding operating parameter through the weld cable and to determine the one or more channel equalization filter coefficients related to the weld cable corresponding to the distortive characteristic.
A method, comprising:
- transmitting an initial reference tone through a weld cable from a low power transmitter coupled to the weld cable;
- receiving a reference tone through the weld cable at the low power receiver;
- applying a digital filter function to the reference tone to determine one or more differences between a template for the initial reference tone and the received reference tone;
- determining one or more channel equalization filter coefficients based on the differences between the template reference tone and the received reference tone;
- and
- compensating for frequency and time dependent amplitude and phase distortion within the weld cable based on the one or more channel equalization filter coefficients.
A welding system, comprising:
- a welding device comprising a low power transceiver configured to be coupled to a weld cable, wherein the low power transceiver comprises:
- a low power transmitter configured to transmit one or more unmodulated tones through the weld cable to a wire feeder;
- a low power receiver configured to receive the one or more unmodulated tones through the weld cable from the wire feeder;
- and
- a first processor configured to:
- determine one or more channel equalization filter coefficients related to the weld cable corresponding to a distortive characteristic of the weld cable;
- and
- apply a digital filter function to the received one or more unmodulated tones, and wherein the digital filter function is configured to determine the one or more channel equalization filter coefficients related to the weld cable.
