发明名称 Vehicle tracking, communication and fleet management system
摘要 A vehicle fleet management information system identifies location and direction of movement of each vehicle in a fleet in real-time, and automatically reports such information, as well as status of predetermined events in which the vehicle is engaged, directly to the fleet manager. One aspect relates to automated reporting of status of a ready mix slurry material truck having a mixer drum. A sensor detects the begin pour event by detecting the mixer drum being run in a discharge direction.
