System for the real time inventory and localization of refrigerating containers and related method
First Claim
1. A system for remotely controlling and monitoring a refrigerator, comprising:
- a control unit for checking and storing a plurality of functioning parameters of said refrigerator, the plurality of functioning parameters including at least a refrigerator current absorption;
a Radio Frequency Identification (RFID) reader for reading data stored in a plurality of RFID tags attached to products stocked in the refrigerator, a communication unit for interconnecting an external device for obtaining information on a geographical localization of said refrigerator,said RFID reader comprising means for retrieving said data from said RFID tags when said products are still stocked inside said refrigerator and said communication unit comprising localization means for transmitting information to said external device on a geographical localization of said refrigerator, andmeans for transmitting said functioning parameters and a delocalization message from the communication unit to a remote server, said delocalization message being transmitted when a number of Global System for Mobile Communications (GSM)/General Packet Radio Service (GPRS) transmission cells connected by the communication unit before a power off and overlapping to GSM/GPRS transmission cells connected by the communication unit after a successive power on is not greater than a predetermined threshold.

Abstract
System (10) for remotely controlling and monitoring a food refrigerator (1), and its content, of the type intended to be given in rental or in free loan from a manufacturer to a vendor of cold products, comprising a control unit (2) for checking and storing a plurality of functioning parameters of the food refrigerator (1), an RFID reader (3) intended to read data stored in a plurality of RFID tags attached to the cold products, a communication unit (4) for interconnecting an external device, the RFID reader (3) comprising means for retrieving data from said RFID tags when the cold products are still stocked inside the food refrigerator (1) and the communication unit (4) localization means for transmitting information to the external device about a geographical localization of the food refrigerator (1). System (10) according to claim 1 wherein said means produce a radio frequency signal at predetermined time intervals for activating said RFID tags. The data stored in said RFID tag comprises a unique identification number. The communication unit (4) is a GSM/GPRS unit. The external devices might be a second food refrigerator, residing in a same local area network (LAN). The external device is a remote server (5) located outside the local area network (LAN) equipped with a management information system.

16. A method for remote control of a refrigerator, comprising the following phases:
-
checking, through a control unit, a plurality of functioning parameters of said refrigerator, the plurality of functioning parameters including at least a refrigerator current absorption; reading, through a Radio Frequency Identification (RFID) reader, data stored inside a plurality of RFID tags attached to product stocked in said refrigerator, said phase of reading being executed when said products are still stocked inside said refrigerator; interconnecting, through a communication unit, an external device, obtaining information on a geographical localization of said refrigerator; and transmitting said functioning parameters and a delocalization message from the communication unit to a remote server, said delocalization message being sent when a number of Global System for Mobile Communications (GSM)/General Packet Radio Service (GPRS) transmission cells connected by the communication unit before a power off and overlapping to GSM/GPRS transmission cells connected by the communication unit after a successive power on is not greater than a predetermined threshold. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)
