Abstract
The invention relates to a device, a method and an apparatus for acquiring data, the device comprising a wireless network including a set of nodes (100), each node (100) including a sender (140) and a receiver (150) for sending and/or receiving and/or relaying data and/or commands, and a satellite positioning system (130), characterized in that each satellite positioning system (130) includes means for providing specific data used for time-stamping the data relative to a common time reference, organizing an access to the wireless network in a perfectly controlled manner, and routing data and/or commands within the network.
Claims15
Data acquisition device formed of a wireless network including a set of nodes (100), each node (100) including a sender (140) and a receiver (150) for sending and/or receiving and/or relaying data and/or commands, and a satellite positioning system (130), characterized in that each satellite positioning system (130) includes means for providing specific data used for:
- time-stamping the data relative to a common time reference,
- organizing an access to the wireless network in a perfectly controlled manner, and
- routing the data and/or commands within the network.
Device according to one of the preceding claims, characterized in that each satellite positioning system (130) includes means for providing specific data used to organize in a controlled manner the allocation of a specific radiofrequency between a sender (140) and a receiver (450), respectively located in separate nodes (100) and (400) of the network.
Device according to one of the preceding claims, characterized in that a node (100) includes at least one sensor (110, 111, 112), at least one analog-digital converter (120, 121, 122) for converting the data from said at least one sensor (110, 111, 112) and means associated with the analog-digital converter (120, 121, 122) for linking time-stamping information with said data.
Device according to one of the preceding claims, characterized in that the satellite positioning system (130) associated with a node (100) includes means for locating the position of the nodes (100) within the network relative to a local geographic reference and means for ascertaining the global time.
Device according to one of the preceding claims, characterized in that each node (100) includes a data storage means.
Data acquisition apparatus characterized in that it is in accordance with a node (100) of the device according to one of the preceding claims.
Method of acquiring data within a wireless network including a set of nodes, said method including steps consisting in:
- sending and/or receiving and/or relaying data and/or commands from at least one node (100) of the network, said node including a sender and a receiver;
- providing specific data from a satellite positioning system (130) located in each node (100) of the network;
- time-stamping the data relative to a common time reference,
- organizing an access to the wireless network in a perfectly controlled manner, and
- routing the data and/or commands sent and/or received and/or relayed within the network.
