Abstract: A system for identifying movers in an independent cart system includes movers having at least one magnet and sensors generating a feedback signal responsive to detecting a magnetic field from the magnet as each mover travels past the sensor. A memory stores an identifier and a corresponding digital fingerprint for each mover. The stored digital fingerprint is generated as a function of the magnetic field generated by the magnet on each mover. A controller receives the feedback signal from each sensor and determines a run-time digital fingerprint for each mover corresponding to the magnetic field generated by the magnet on each mover as a function of the feedback signal. The run-time digital fingerprint is matched to one of the stored digital fingerprints, and the identifier, corresponding to the stored digital fingerprint matching the run-time fingerprint, is read from memory.

Abstract: A system includes processing circuitry and a memory. The memory stores instructions that, when executed by the processing circuitry, cause the processing circuitry to receiving operational data captured from an industrial automation system performing an industrial automation process, model the industrial automation process based on the operational data, model one or more adjustments to the industrial automation process, identify that the modeling of the one or more adjustments to the industrial automation process indicates that the one or more adjustments to the industrial automation process improve one or more sustainability metrics for the industrial automation process, generate one or more sustainability recommendations to implement the one or more adjustments to the industrial automation process, and implement the one or more adjustments to the industrial automation process.

Abstract: A system for detecting linear drive system faults includes a track, a calibrated inspection apparatus, and processing circuitry. The track includes track segments defining a path along which movers travel. Drive coils induce travel of the movers along the track. The calibrated inspection apparatus includes (i) a calibrated inspection mover that travels along the track and/or (ii) a calibrated inspection station including one or more of the track segments. The processing circuitry obtains feedback signals from controllers for the track segments. The feedback signals characterize relative motion between the calibrated inspection apparatus and (i) the track segments and/or (ii) the movers. The processing circuitry determines a fault based on the feedback signals and calibrated characteristics of the calibrated inspection apparatus. The fault includes at least one of (i) a track segment fault in the track segments or (ii) a mover fault in the movers.

Abstract: A system includes one or more movers configured to move along a track of an industrial automation system and a computing device. The computing device receives data associated with the movers as the movers move around the track. The data includes a first amount of time for at least one of the movers to move between two stations disposed along the track, a second amount of time for the at least one mover to settle at a station, a third amount of time for a respective robot at the station to prepare to perform a process, and a fourth amount of time for the respective robot to perform the process. The computing device identifies throughput degradation based on the first amount of time, the second amount of time, the third amount of time, or the fourth amount of time, or any combination thereof.

Abstract: A motion control system for an independent cart system provides for an improved system for controlling operation of movers in areas of high traffic. A controller monitors operation of the movers to detect heavy traffic. In heavy traffic, the controller may bring a mover to a stop to avoid collisions. Once a mover is stopped, the segment controller will look at the present location of the mover and determine whether it is at the desired position set in the motion command. If the mover is not at the desired position, the stop was a result of heavy traffic. After detecting heavy traffic, the controller commands the mover to resume travel using a modified motion command. The modified motion command will command the first mover to its desired position but will command the move at a reduced rate or using a reduced response in the controller.

Abstract: A system for controlling movers in a linear drive system includes a plurality of movers and a track providing segments along which the movers may travel and holding driver coils and a segment controller controlling the driver coils. Some of the segments having switches forming branches between segments. A central controller communicates operates with the segment controllers to route the movers along the track by distributing routing decisions for a given mover to a segment controller for a track on which a given mover is currently traveling.

Abstract: An improved system for preventing collisions between movers while improving throughput in a linear drive system utilizes a continually variable vehicle length for each mover. A vehicle length is assigned to each mover, where the vehicle length is a minimum track length required by the vehicle to avoid physically contacting a neighboring vehicle along the track. The vehicle length for each mover is then determined for each location along the track based on both the track geometry and the mover geometry. The vehicle length is continually variable along the length of the track allowing movers to be positioned as close together as possible for each location along the track based on both the track geometry and the mover geometry. The continually variable vehicle length provides collision prevention between movers while increasing throughput of movers along segments of the track that do not require the largest spacing between movers.

Abstract: An improved system and method for monitoring operation of movers in an independent cart system reduces the required communication bandwidth for monitoring operation of movers in a system where control is distributed among multiple controllers spaced along the track. As the mover is travelling along the track segment, each distributed controller monitors at least one operating characteristic of the mover. As a mover travels along the track, each distributed controller transmits the operating characteristic to a successive distributed controller, such the monitored operating characteristic is transmitted along the track as the mover travels along the track. At a reduced rate or upon request from a central controller, each distributed controller may transmit the status of a mover present on the corresponding track segment controlled by that distributed controller to the central controller.

Abstract: A system for distributing wear on multiple movers in an independent cart system includes a machine learning model executing on a processor. The machine learning model may include models of operation for each of the movers, and the machine learning model is operative to receive multiple inputs for each of the movers. Each of the inputs corresponds to an operating condition for one of the movers as the mover travels along a track for the independent cart system. Each of the inputs are received for each of the movers over multiple runs along the track, and the inputs received generate a training set of data for the movers. A weighting value is determined for each of the movers as a function of the training set of data, where the weighting value corresponds to a level of wear present on each of the movers.

Abstract: A system and method for holding position of a mover in an independent cart system includes receiving a current feedback signal corresponding to a current present in at least one coil for a linear drive system in the independent cart system. A motion command for the mover is received, where the motion command defines a desired position along a track of the independent cart system to which the mover is to travel. An electromagnetic pinning control mode is disabled while controlling operation of the at least one mover to the desired position and enabled when the at least one mover is at the desired position.
