Abstract

An animal such as a dairy cow carries a transponder unit which includes a motion sensor. When the animal comes within range of a transceiver unit, it is interrogated and the transponder unit transmits data which identifies the animal and indicates the number of movements of the animal. The number of animal movements increase dramatically during estrus and a record is kept on each animal to determine when this occurs. Data received at the transceiver is processed by a microprocessor based system which operates to insure the received data is correct. It also assembles the data and outputs it to a printer.

Claims

1. An estrus detection system for an animal, the combination comprising:

a transponder unit mounted to the animal, and including

(a) a motion sensing device which provides an electrical signal in response to animal movement,

(b) a counter coupled to said motion sensing device to receive said electrical signals and store a number which is indicative of the number of animal movements, and

(c) means responsive to an interrogation signal for transmitting data indicative of the number stored in said counter;

a transceiver unit positioned near a location which the animal frequents, said transceiver unit including

(d) means for generating an interrogation signal to said transponder unit,

(e) means for receiving the data transmitted by said transceiver unit,

(f) means coupled to said receiving means for converting said received data into an activity number which is indicative of the number of animal movements, and

(g) means coupled to said converting means for displaying information which incorporates said activity number.

2. The estrus detection system as recited in claim 1 in which said transponder unit also includes means for transmitting data which identifies the animal to which it is attached and said transceiver unit converting means converts this data into an identification number and couples it to said display means.

3. The estrus detection system as recited in claims 1 or 2 in which said transponder unit is attached to the neck of the animal.

4. An animal identification and estrus detection system, the combination comprising:

a transponder unit mounted to the animal and including

(a) a motion sensing device which provides an electrical signal in response to animal movement,

(b) a counter coupled to said motion sensing device to receive said electrical signals and store an activity number which is indicative of the number of animal movements,

(c) means for generating an animal identification number,

(d) means responsive to an interrogation signal for transmitting data indicative of a number applied to its input terminal,

(e) means coupled to said counter and said generating means for sequentially applying the identification number and the activity number to the input terminal of said transmitting means;

a transceiver unit positioned near a location which the animal frequents, said transceiver unit including

(f) means for generating an interrogation signal to said transponder unit,

(g) means for receiving the data transmitted by said transponder unit,

(h) means coupled to said receiving means for converting said data into an activity number and an animal identification number, and

(i) means coupled to said converting means for displaying the activity number and the animal identification number.

5. The animal identification and estrus detection system as recited in claim 4 in which said means for displaying the activity number and animal identification number includes a microprocessor coupled to said converting means by a data bus and a printer coupled to said microprocessor through said data bus.

6. The animal identification and estrus detection system as recited in claim 5 in which said microprocessor is programmed to repeatedly input said activity number and the animal identification number from said converting means, to compare successively received activity numbers and animal identification numbers, and to output said activity number and animal identification to said display when a preselected number of identical numbers are compared.

7. The animal identification and estrus detection system as recited in claim 4 in which said converting means includes a counter which is coupled to said interrogation signal generating means and said receiving means, said counter being incremented by said generating means and the contents of said counter being coupled to said display means in response to the data transmitted by said transponder unit.

8. A transponder unit for mounting to an animal and being responsive to an interrogation signal generated by a transceiver unit to generate a signal to said transceiver unit which indicates the identity of the animal to which the transponder unit is attached and which indicates the activity of the animal, the combination comprising:

a motion sensing device which provides an electrical signal in response to animal movement;

a counter coupled to said motion sensing device to receive said electrical signals and store a number which is indicative of the number of animal movements;

a presettable counter having an input connected to receive said interrogation signal, an output terminal connected to generate said signal to said transceiver unit and a set of present terminals;

means having inputs connected to said counter and outputs connected to said presettable counter preset terminals for coupling a number from said counter to said presettable counter when enabled;

means coupled to said presettable counter preset terminals for applying an identication number to said presettable counter when enabled; and

means coupled to the output terminal of said presettable counter for sequentially enabling said last two named means.

9. An estrus detection system for an animal, the combination comprising:

a transponder unit mounted to the animal, and including

(a) a motion sensing device which provides an electrical signal in response to animal movement,

(b) accumulator means coupled to said motion sensing device to receive said electrical signals and store a signal which is indicative of the number of animal movements, and

(c) means responsive to an interrogation signal and coupled to said accumulator means for transmitting data indicative of the number of animal movements;

a transceiver unit positioned near a location which the animal frequents, said transceiver unit including

(d) means for generating an interrogation signal to said transponder unit,

(e) means for receiving the data transmitted by said transceiver unit,

(f) means coupled to said receiving means for converting said received data into an activity number which is indicative of the number of animal movements, and

(g) means coupled to said converting means for displaying information which incorporates said activity number.

10. The estrus detection system as recited in claim 9 in which said transponder unit also includes means for transmitting data which identifies the animal to which it is attached and said transceiver unit converting means converts this data into an identification number and couples it to said display means.
