摘要：
A detection system for an agricultural header includes a belt that has at least one physical feature driven by a roller at a roller rotational speed. The detection system also includes a sensor that detects a physical feature as it passes the sensor during rotation of the belt. The detection system further includes a controller that receives a signal indicating a first pulse of a first time a physical feature passes the sensor during the rotation of the belt and a second pulse of a second time a physical feature passes the sensor during the rotation of the belt. The controller further determines a pulse frequency based on the first and second times and calculates a belt rotational speed based on the pulse frequency. The controller compares the belt rotational speed to the roller rotational speed and provides an output if the roller rotational speed exceeds a threshold.
