Sensor-based power controls for a welding system
A welding system includes a torch motion sensing system associated with a welding torch and is configured to sense welding torch orientations or movements. The welding system also includes a processing system that is configured to vary operation of a power source based on the sensed orientations or movements.
1. A welding-type system, comprising:
a power source;
a motion sensing system associated with a welding-type tool or accessory and configured to sense an orientation or movement of the welding-type tool or accessory; and
a processing system communicatively coupled to the motion sensing system and configured to:
determine a change in the orientation or movement of the welding-type tool or accessory prior to a power demand from the welding-type tool or accessory;
determine a type of the welding-type tool or accessory associated with the motion sensing system;
based on the type of the welding-type tool or accessory, select a power level sufficient to perform a welding-type operation using the welding-type tool or accessory;
send an indication to energize the power source to provide power at the selected power level, the selected power level being sufficient to operate a welding-type process of the power source or operator tools connected to the power source;
determine that the welding-type tool or accessory has not moved for a duration of time;
determine whether the duration of time exceeds a first threshold or a second threshold;
when the duration of time exceeds a first threshold, place the power source in a first power state; and
when the duration of time exceeds a second threshold, place the power source in a second power state, wherein the first and second power states are altered power generation states from an initial power state.
2. The welding-type system of claim 1 , wherein placing the power source in the first power state comprises sending an indication to the power source to reduce power generation to a low-power level that is lower than the ready level when the welding-type tool or accessory has not moved for the duration of time.
3. The welding-type system of claim 1 , wherein first power state comprises an idling engine state and the second power state comprises an engine off state.
4. The welding-type system of claim 1 , comprising a transceiver configured to transmit information indicative of the determined change in the orientation or movement of the welding-type tool or accessory to the power source.
5. The welding-type system of claim 1 , wherein the motion sensing system comprises at least one accelerometer.
6. The welding-type system of claim 1 , wherein the motion sensing system is configured to determine one or more predefined gestures, and the processing system is configured to change a corresponding weld process parameter by progressing through a plurality of welding-type process states based at least in part on the determined one or more predefined gestures.
7. The welding-type system of claim 1 , comprising a feedback unit configured to provide an alert that the power source is ready to deliver power at one or more power levels.
8. The welding-type system of claim 1 , comprising an energy harvester configured to provide power for operation of the motion sensing system or the processing system.
9. The welding-type system of claim 1 , wherein placing the power source in the first power state comprises placing the power source in the first power state from an operating state.
10. The welding-type system of claim 1 , wherein the processing system is configured to determine a type of the welding-type tool or accessory associated with the motion sensing system based on a tool tag associated with the motion sensing system.
11. The welding-type system of claim 3 , wherein the power source comprises a combustion engine.
12. The welding-type system of claim 5 , wherein the motion sensing system comprises at least one angular rate sensor configured to measure angular changes of the welding-type tool or accessory.
13. The welding-type system of claim 7 , wherein the alert comprises haptic, visual, or audio feedback.
14. A retro-fit kit configured to couple to a welding-type tool or accessory, comprising:
a motion sensing system configured to determine orientation of the welding-type tool or accessory;
a processor communicatively coupled to the motion sensing system and configured to:
determine a type of the welding-type tool or accessory associated with the motion sensing system;
based on the type of the welding-type tool or accessory, select a power level sufficient to perform a welding-type operation using the welding-type tool or accessory;
send the indication to energize the power source to provide power at the ready level by sending the indication to energize the power source at the selected power level; and
send instructions to a power supply for the welding-type tool or accessory to:
provide power in response to movement of the welding-type tool or accessory or in response to a change in orientation of the welding-type tool or accessory, wherein the instructions comprise instructions to reduce power from the power supply when the motion sensing system determines that the determined orientation corresponds to a predefined orientation of the welding-type tool or accessory.
15. The retro-fit kit of claim 14 , wherein the processor is configured to send instructions to the power supply to reduce power production when no movement or change in orientation has been detected for a predetermined duration of time.
16. The retro-fit kit of claim 14 , wherein the predefined orientation corresponds to an orientation indicative of idleness of the welding-type tool or accessory.
17. The retro-fit kit of claim 14 , wherein the predefined orientation comprises the welding-type tool or accessory laying on its side, being upside down, or laying with a working end facing downward.
