Patent ID: 8907784

Claim:
A system for managing geographically distributed resources, comprising: a plurality of shoes associated with said resources; a local concentrator ( 31 ) external to said shoes, and a remote operation centre ( 32 ); each pair of said plurality of shoes comprising an electronic circuit ( 1 ) placed in said shoes; said electronic circuit ( 1 ) comprising a control circuit ( 11 ) for said electronic circuit ( 1 ); a locator module ( 13 ) arranged to provide geographical coordinates to said control circuit ( 11 ); and a radio communication system ( 12 ); said control circuit ( 11 ) arranged to provide a plurality of information items to said radio communication system ( 12 ); said radio communication system ( 12 ) comprising a first receiver-transmitter, for a wireless short range of communication, to send said plurality of information items to said local concentrator ( 31 ); said local concentrator ( 31 ) is connected with said radio communication system ( 12 ); said local concentrator ( 31 ) comprising a second receiver-transmitter, for a wireless long range of communication, arranged to send said plurality of information items to said operations centre ( 32 ); said first receiver-transmitter sending said plurality of information items to said local concentrator ( 31 ) periodically; said control circuit ( 11 ) comprising an input connected to at least one sensor ( 20 ); said at least one sensor ( 20 ) comprises a meter for measuring the voltage of a battery ( 10 ) powering said electronic circuit ( 1 ); said plurality of information items comprises said geographical coordinates which give the location of said control circuit ( 11 ) and the voltage of said battery ( 10 ); said operations centre ( 32 ) displaying the location of each of said control circuit ( 11 ) and the voltage of said battery ( 10 ), so that said operations centre ( 32 ) reduce the transmission period of sending said plurality of information items from said first receiver-transmitter to said local concentrator ( 31 ) periodically, to control the battery consumption, and further modify the transmission period between the local concentrator ( 31 ) and the operations centre ( 32 ).
