Machine Alert When Stopping on Hot Asphalt

摘要

An alert system in equipment used in an asphalt paving environment, such as a compactor, signals an operator when the equipment is stopped on hot asphalt, potentially over-compacting the area where the equipment is located. The alert system includes a surface temperature sensor so that the alert is only activated when there is a risk of over-compaction because the asphalt is still above a threshold temperature. The alert system may also include a timer so that the operator is not signaled during routine stopping associated with changing direction during compacting operations.

主权项

1. An alert system for use in a compactor for an asphalt paving operation comprising:
a speed sensor; a pavement temperature sensor; an operator alert device configured to activate an alert to an operator when a command is received; and a controller that:
determines, via the speed sensor, that the compactor is stopped;determines, via the pavement temperature sensor, that a pavement temperature proximate the compactor is above a threshold temperature; andissues the command that activates the operator alert device.
