<p>An automated material handling system utilizing one or more train-type guided vehicles (12) moving along a rail (10) with each train including a locomotive (14) pulling a plurality of trolleys (16). Each trolley includes a tiltable tray (26), an onboard CPU (44), and onboard sensors (94a, 94b, 96, 98) for sensing information with respect to the product (22) being carried by the tray. The sensed information is transmitted to the CPU of the trolley where it is stored and also transmitted to a CPU in the locomotive. The locomotive CPU (107) is in radio frequency contact with an off-track dispatch computer (19) controlling the overall operation of the material handling system. The CPU of each trolley is also in infrared communication with local CPU's positioned at unloading stations so that the CPU of each car may receive information by infrared transmission from local CPU's.</p> |
