System and method for the monitoring of grouped objects
First Claim
1. A system for monitoring objects within a group comprising:
- a plurality of radio nodes each of which is attached to a respective one of the objects in the group;
at least one gateway that receives and transmits signals between the plurality of radio nodes and an information system,wherein each radio node hasat least one computing unit,a short-range communications unit for wireless communication with other radio nodes of the plurality of radio nodes and with the at least one gateway, andan energy supply unit,wherein at least one of the radio nodes or the at least one gateway has a localization unit,wherein the computing unit contains at least one control program for processing predetermined tasks in the plurality of radio nodes, said control program controlling bi-directional communications between the plurality of radio nodes via the short-range communications unit for the formation of an ad hoc network and controlling bi-directional communications between the plurality of radio nodes and the at least one gateway via the short-range communications unit and controlling a tuning process between the plurality of radio nodes, said tuning process being executed at one of predetermined time intervals, predetermined times, according to a requirement received via the at least one gateway or by an event detected by one of the plurality of radio nodes in order to select one of the plurality of radio nodes for the processing of one of the predetermined tasks, where the selected radio node is best suited for the task according to predetermined criteria at the instant selection is made.

Abstract
A system and a method for monitoring grouped objects with a gateway and a plurality of radio nodes attachable to the objects. Each radio node has a computing unit, a short-range communications unit and an energy supply unit. One of the radio nodes or the gateway has a localization unit. Optionally, one of the radio nodes also has a long-range communications unit. The computing unit contains a control program for the processing of predetermined tasks in radio nodes, which is designed for the control of bi-directional communications between the radio nodes via the short-range communications unit for the formation of an ad hoc network. The control program undertakes the control of a tuning process between the radio nodes and selects one of the radio nodes for the processing of one of the predetermined tasks, the selected node at that instant being best suited for the task according to predetermined criteria.
