US Patent 10267103 System for monitoring pipe-retaining structures

Methods for monitoring the movement of latch members using wireless sensors include receiving wireless sensor data that indicates the rate of movement of a latch member toward an open or closed position. Based on correspondence between the rate of movement and latch function data that associates movement rates with functionality and life expectancy of latch members, the health and useable life expectancy of the latch member may be estimated. Additionally, if the movement of the latch member does not fall within threshold minimum and maximum values, or if the movement of a latch does not correspond to a command, output indicating a malfunction may be generated or pipe moving operations associated with the latch member may be canceled.
