Livestock management system

A system for monitoring livestock behavior, the system comprising:

• a wire loop to be physically associated with at least one feedlot feature, the feedlot feature capable of a behavioral interaction by the livestock;
• a wire driver for driving a very low frequency (VLF) radio signal through the wire loop;
• a plurality of mobile transceivers, each one of the plurality of mobile transceivers capable of being worn by the livestock and including:
• at least one wire coil configured for a magnetic coupling with the wire loop by the very low frequency radio signal when sufficiently close to the wire loop,
• circuitry for determining a magnetic field strength when magnetically coupled with the wire loop, and
• a processor for determining when to report a proximity to the wire loop based upon the determined magnetic field strength;
• a base station configured for bidirectional communications with the plurality of mobile transceivers and including at least one of a wireless computer networking interface or a mobile communications device interface for communicating information received from the plurality of mobile transceivers.

A system for establishing and maintaining communications with a multiplicity of mobile transceivers, the system comprising:

• a plurality of mobile transceivers, each one of the plurality of mobile transceivers comprising:
• a sensor configured to frequently determine characteristic information within an environment proximate to the mobile transceiver,
• a limited memory configured to temporarily store the characteristic information, and
• a controller configured to transmit the characteristic information from the mobile transceiver;
• and
• a base station configured for bidirectional communications with the plurality of mobile transceivers, the base station comprising:
• a radio frequency receiver configured to receive transmissions from the plurality of mobile transceivers within a plurality of timed reception slots, each one of the plurality of timed reception slots assignable to one of the plurality of mobile transceivers,
• a radio frequency transmitter configured to broadcast an intermittent beacon signal to the plurality of mobile transceivers within a timed transmission slot, the intermittent beacon signal indicating timing of the timed transmission slot, timing of the plurality of timed reception slots, identifications of individual ones of the plurality of timed reception slots assigned to individual ones of the plurality of mobile transceivers, and identifications of individual ones of the plurality of timed reception slots that are unassigned, and
• a controller configured to analyze transmissions received from the plurality of mobile transceivers within the plurality of timed reception slots to identify a transmission from an unassigned mobile transceiver of the plurality of mobile transceivers received during an unassigned reception slot of the plurality of timed reception slots and assign the unassigned reception slot to the unassigned mobile transceiver, wherein the characteristic information from the mobile transceiver can be transmitted from the mobile transceiver to the base station frequently enough to limit an amount of required storage space in the limited memory of the mobile transceiver.

A system for detecting a behavioral anomaly in a feed animal and indicating an intervention, the system comprising:

• a wire loop to be physically associated with at least one feedlot feature, the feedlot feature capable of a behavioral interaction by the feed animal;
• a wire driver for driving a very low frequency (VLF) radio signal through the wire loop;
• a plurality of mobile transceivers, each one of the plurality of mobile transceivers capable of being worn by the feed animal and including:
• at least one wire coil configured for a magnetic coupling with the wire loop by the very low frequency radio signal when sufficiently close to the wire loop,
• circuitry for determining a magnetic field strength when magnetically coupled with the wire loop,
• a processor for determining when to report a proximity to the wire loop based upon the determined magnetic field strength, and
• an indicator for indicating the intervention for the feed animal;
• a base station configured for bidirectional communications with the plurality of mobile transceivers and including at least one of a wireless computer networking interface or a mobile communications device interface for communicating information received from the plurality of mobile transceivers;
• a data silo for storing historical data on the feed animal and its proximity to the wire loop communicated from the base station;
• and
• a controller coupled with the data silo for analyzing the historical data on the feed animal to determine the behavioral anomaly in the feed animal associated with the intervention and instructing a mobile transceiver associated with the feed animal to indicate the intervention.
