ABSTRACT:
Data from vending machines are acquired by a resident data acquisition unit (DAU) implanted in each vending machine. This unit senses coins in, coins out, products dispensed and door openings, among other activities, and provides a data base which records all of these activities. Each vending machine data acquisition unit (DAU) is interrogated by a data transfer unit (DTU) carried by a route service person and the information from each DAU is stored in the data transfer unit. The data transfer unit then disgorges the recorded information in a central data converting unit (DCU) which services a number of DTUs. The data converting unit provides an instant summary of the information by vending machine and route, and also converts the information to standard computer language for subsequent processing in a full-size computer.
