METHOD FOR MONITORING OF MOBILE OBJECTS Russian patent published in 2000 - IPC

FIELD: systems for production, supplying and selling goods. SUBSTANCE: method involves placing labels, which are designed as carriers of encoded signal, onto objects, which are located in initial position, and periodic reading encoded signals from carriers. Preliminary method involves generation of two types of signals, which are stored in checkpoint, and encoding and placing said signals onto carriers as bar codes. Said carriers serve as labels on objects and accompanying documents. Signals from carriers, which are read at least once a day, are compared to stored values. In case, if deviation is detected, decision is made about possible violations. Signals which correspond to objects left out of monitoring by authorized procedure are removed from stored signal sequence. EFFECT: on- line monitoring of movements of separate objects and flows of objects. 3 cl, 1 dwg
