Method and a device for monitoring physical conditions

Abstract

A method for monitoring the physical conditions of products, such as food-stuff and similar, wherein a plurality of detectors associated to nodes (25; 31) is arranged close to the food-stuff. A detector (26; 34) continuously measures at least one physical condition of a product. The nodes (25; 31) establish continuously and periodically a wire-less contact with the central unit (12), said nodes and said central unit being part of a local installation, and also transfer measured data from the detectors (26; 34) to the central unit (12). The central unit (12) continuously stores the received measured data and continuously and periodically establishes a wireless contact with a server (11) connected to the Internet for the transfer of stored measured data. Information related to the transferred measured data is made available on the server (11) to be reviewed through the Internet. The central unit (12) comprises a first communication means (14) for a wireless communication with a web server (11) connected to the Internet and a second communication means (16) for a wire-less communication with the nodes. The nodes comprise a communication means (17) corresponding to the second communication means for having a wire-less communication with the second communication means. Furthermore, the nodes comprise detectors (12; 34) and detector elements (27; 39) for recording data relating to the physical condition of the object. The nodes are arranged to continuously and periodically establish a wireless contact with a central unit (12) comprising a storage unit (53) for storing a plurality of measured data from a plurality of nodes.
