Abstract: A machine at a worksite may be assigned to one or more production circuits that each include a sequence of activities. Each activity in a production circuit may associated with corresponding entry criteria indicating conditions that, if satisfied by the machine, permit the machine to initiate performance of that activity. The machine may perform activities of a production circuit if the machine satisfies the corresponding entry criteria. If the machine does not satisfy entry criteria of an activity in an assigned production circuit, the machine may switch to performing activities of a different production circuit, such as a lower-priority production circuit that has also been assigned to the machine, that includes an activity with entry criteria that the machine does satisfy.

Abstract: A worksite tracking system uses sensor data associated with operations of a machine on a worksite to detect when the machine performs a dump event to dump material at the worksite, and to update tracking data that tracks machine operations and material movement at the worksite. If sensor data causes detection of a false dump event that did not actually occur, the worksite tracking system identifies the detected false dump event and suppresses corresponding information to update and correct the tracking data.

Abstract: A liquid-dispensing vehicle, such as a water truck, may deliver water from a tank through spray heads to combat dust at a worksite during a mission. Operating in an environment with potentially low-bandwidth and intermittent communications, the vehicle periodically transmits timestamped data relating to a tank level, truck movement, and a binary status of the spray heads to an external computing system. The computing system virtually reconstructs the operation of the truck and treatment of the worksite by building timelines and coverage maps from the timestamped data. In generating a smoothed water-level timeline, the system identifies refilling sections, stable sections, and draining sections of the tank from the timestamped data and filters noisy water readings during the draining sections. An activity timeline identifies various truck activities during the watering mission, and a coverage map builds a two-dimensional rendering of water treatment on the worksite based on geometric patterns of the active spray heads, all of which may be used to evaluate the mission or to control future operation of the vehicle.
