Description

The utility model relates to agriculture, in particular, to the means used in veterinary medicine for the correct selection of the time of insemination of cows and heifers.

When using artificial insemination of farm animals, the correct choice of the time of insemination is one of the important factors determining the most complete use of the biological capabilities of the breeding stock.

The determination of the time of insemination along with the diagnosis of hunting also contributes to the solution of such important problems as the diagnosis of pregnancy and infertility. Timely identification of infertile cows allows us to develop and implement a set of therapeutic and preventive measures with the greatest economic efficiency. With the wrong time of insemination, clinically healthy animals remain infertile (without a fetus in the uterus). In this case, economic losses are due to both the omission of reproductive cycles and the lack of fertilization of animals during their insemination outside of hunting. Thus, the period of time from calving to fertilization is lengthened and the time of infertility of animals increases.

A known system for determining the optimal insemination time of cows and heifers, which contains an information reader installed in the control zone, including two antennas with transceiver devices connected to them, the outputs of the receiving channels of the transceiver devices are connected to the input of the signal processing unit, to the output of which a memory unit connected through the matching unit with the input of the computing unit connected to the computer and the sensors placed on the body of the controlled animals, each sensor consists um from an antenna with a receiver and a transmitter connected to it, the output of the receiver being connected to the control input of the transmitter, the frequency of the signal emitted by the transmitter is fixed, and its value is set in accordance with the identification code of the animal,

for which it is predefined. The sensor used in the proposed system can be made with an autonomous power source, or with the possibility of power from the energy of the probing signals (RU 44495 U1, A 61 D 19/00, Bull .. No. 9, 03/27/05).

The disadvantages of the known system are the need for constant (throughout the control time) sensing of the controlled zone of the space within which the animals are located, and increased energy consumption due to the formation of sounding signals throughout the control time.

A known system for determining the optimal time for insemination of cows and heifers, which is closest to the proposed one and contains a stationary information reader including a series-connected antenna, receiving device, signal processing unit, memory unit, matching unit and computing unit connected to a computer, sensors (transponders) placed on the body of controlled animals, each sensor (transponder) consists of an antenna with a receiver and transmitter connected to it, the output of the receiver is connected the control input of the transmitter, the frequency of the signal emitted by the transmitter is fixed, and its value is set in accordance with the identification code of the animal, for which it is pre-specified, wherein the transponder is adapted to be power of probing signals power. At the same time, it is equipped with an interrogator (reader) placed on an animal-detector containing an antenna with a transceiver and an acceleration sensor, the output of which is connected to the control input of the transceiver, and the output of the transceiver through a power amplifier is connected to the second antenna (RU 46427 U1 A 61 D 19/00, Bull. No. 19, 07/10/05).

The disadvantages of this known system are the increased power consumption of the interrogator, placed on a detection animal, due to the need to read and transmit an identification code of a cow (heifer), which is in a state of sexual hunting, over long distances, as well as insufficient reliability of detecting sexual hunting of a particular animal from due to errors in reading and transmitting

identification radio frequency code to a stationary information reader.

The technical result of the proposed utility model is to simplify the design, increase efficiency by reducing the energy consumption of the interrogator, placed on the animal-identifier, as well as by increasing the reliability of revealing sexual hunting by reducing the reading function of the identification radio frequency code of the cow (heifer) and thereby eliminating errors when reading.

The technical result is achieved due to the fact that in the system for determining the optimal time for insemination of cows and heifers, containing a stationary information reader including a series-connected antenna, a receiving device and an information display device, at least one configured to place a controlled animal on the body transponder for fixing sexual hunting, including an antenna with a receiver and transmitter connected to it, configured to be placed on an animal the interrogator containing an acceleration sensor connected to a transmitter with an antenna, the stationary reader is equipped with a transmitter connected to the antenna, and the transponder for fixing sexual hunting contains a control unit whose input is connected to the receiver and the output to the transmitter.

In addition, the information display device can be made in the form of a light and / or sound signaling device.

The system for determining the optimal time for insemination of cows and heifers with the above set of features has reduced power consumption due to the reduced power consumption of the interrogator placed on the animal-revealer and increased reliability of the identification of sexual hunting.

This is ensured by the fact that the device placed on the cow (heifer), in the case of the admission of this cow cage probe signals that it is in the state of sexual hunting in the form of a logical "1" when passing through a stationary information reader. In this case, for example, when animals return to the farm after a walk, the indicator on the stationary reader will turn on

information. Those. information about the state of sexual hunting of a cow is transmitted over the air as a single bit in the binary system and is read from close range, which reduces the error in reading and transmitting information about the state of sexual hunting transmitted from the prototype in the form of an identification code (64 bits in the binary system in accordance with international standard ISO 11784) and increases the reliability of the identification of sexual hunting of an animal.

The drawing (figure 1) shows a functional diagram of a system for determining the optimal time for insemination of cows and heifers.

The system for determining the optimal time for insemination of cows and heifers contains a stationary information reader 1, including connected to the antenna 2, a transmitting device 3 and a receiving device 4, to the output of which is connected an information display device 5, at least one transponder 6 for fixing sex hunting made with the possibility of placing on the body of a controlled animal (cows and heifers), each of which consists of an antenna 7 with a transmitter 8 and a receiver 9 connected to it, the output of which is connected through troystvo control 10 to the input of transmitter 8. The frequency of the emitted signal transmitter 8 is the same for all cows (heifers) and it is set in advance. The system includes a requestor 11 arranged to be placed on an animal-detector, comprising an acceleration sensor 12 connected to a transmitting device 13 with an antenna 14.

The interrogator 11, which is installed on the detection animal, is supplied with power from an autonomous power source, for example, from a miniature battery or battery.

The system for determining the optimal time for insemination of cows and heifers works as follows.

When the detection animal (test bull or detection cow) jumps up, the acceleration sensor 12 located on its body is activated, the signal from which goes to the control input of the transmitting device 13 and is emitted through the antenna 14. The emitted signal is received by the antenna 7 placed on the body of the controlled animal responder 6 and through the receiver 9 enters the control device 10, which stores information about

the admission of the cow (heifer) of the probe charge, for example, the capacitor is charging, or the trigger is turned on.

When the controlled animal passes near the stationary reader 1, the probing radio signal from the transmitting device 3 through the antenna 2 with a frequency different from the signal emitted by the interrogator 11, placed on the detection animal, enters through the antenna 7 to the receiver 9 and then to the control unit 10. This starts a transmitter 8, which through the antenna 7 transmits to the antenna 2 a radio signal corresponding to a logical “1” from the animal that allowed the probe to be charged and then to the receiving device 4 and the information display device 5 and a stationary reader 1. The start of the transmitter 8 can be performed, for example, when the capacitor is discharged or the trigger is switched. After transmitting information by the transmitter 8, the responder 6 returns to its original state.

In the absence of a probing signal from a stationary reader of information 1, responders 6, placed on the body of controlled animals (cows), are in standby mode and do not generate response signals. The power of the responder 6 may be directly from the energy of the received sounding signal.

When the herd passes near the stationary reader 1, an information display device, for example, a light indicator, signals the passage of an animal in a state of sexual hunting. According to the information received, the inseminator draws conclusions about the optimal time for insemination of cows and heifers.

The proposed system has simplicity, increased efficiency due to the low power consumption of the interrogator placed on the animal-identifier, higher reliability of determining the sexual hunting of the animal, and high reliability due to the reduction of technical means of information processing.
