Title
(EN) SMART LOAD PIN FOR DRAW-WORKS
(ZH) 用于绞车的智能载荷销钉
Abstract
(EN)
A smart load pin may be configured to measure a load on a hook of a draw-works system. The smart load pin may also include circuitry to convert the measured load to a digital value representative of the measured load, wherein the digital value represents the value of the measured load in engineering units and to transfer the digital value representative of the measured load to a control system located at a derrick. The data from the smart load pin may be used in adjusting, with a control system, operation of the draw-works system based, at least in part, on the received digital value representative of the measured load.
