    摘要: A retail merchandise pusher is configured for sliding along a pusher assembly track. The pusher assembly is mountable to a retail merchandise shelf. The pusher includes a housing, a spring drum rotatably mounted within the housing, and a coil spring mounted to the spring drum. The coil spring is coilable and uncoilable upon rotation of the spring drum. A controller is coupled to a sensor arrangement within the housing. The sensor arrangement has a spring drum sensor for detecting rotation of the spring drum. A direction sensor detects a direction of rotation of the spring drum. An incremental distance sensor detects incremental movement of the pusher. The controller is configured to calculate, based on data from the sensor arrangement, a total distance and direction of travel by the pusher, and to generate an alarm when the pusher travels more than a threshold distance within a predetermined period of time.
