The invention relates to agriculture, in particular to keeping animals in conditions in livestock buildings, mainly to technology, local heating of the young and General space heating.

With the existing technology of keeping animals (e.g. pigs), guided by the instinct of group behavior, leaving the area of the heated brooder feeding or playing. At the same time, the staff conducts a visual inspection for the fallen and sick (hereinafter unhealthy) animals in the zone of heating and carries out their culling. This operation is accompanied by the disruption of thermal regime of the brooder when lifting or opening and causes stress in animals associated with man's appearance near the habitats of animals, so this operation should be carried out for certain, but currently effective technical solutions for control and signaling the presence of unhealthy farm animals in the zone of heating does not exist.

Example of the implementation of these methods and the device is in technical solutions are to A.S. 860018 the USSR, MKI3G 05 D 23/00, And 01 To 29/00. Device for infrared heating of piglets. / Vcharter // Opening. Of the invention. 1981, No. 32 and A.S. 1637723, And 01 To 29/00. The heating device of young farm animals and poultry. /Wellensteyn, Powderless, Auvin, Aviici, Vchodove, Vinashin, Characterising etc. // Opening. Of the invention. 1991. No. 12.

The known device for implementing the method of infrared heating piglets on A.S. 860018 uses the behavior of the animal to occupy the area with a comfortable thermal conditions and unconscious mechanical influence on the mechanical portion of the electrical contact located in the area of heating, resulting in the device is formed by a control signal that causes the inclusion of the additional heater.

The closest in technical essence of the present invention is a method implemented in the device according to A.S. 1637723 generating the control signal of the presence of the animal in the zone heater when the animal is in the area of heating, which also causes a change in the mode of the heating zone with the animal, bringing the heat mode to comfortable.

Shortcomings listed and analog prototype is the inability to control for unhealthy animals or animals whose behavior differs from prenatal the technology content (for example, for animals with delayed physiological development). As a result, it is possible not controlled by the personnel of the occurrence of diseases of livestock in conditions of semi-enclosed volume brooder. In the uncontrolled spreading of infection possible loss of the entire population in the area of heating, and around the premises with a local heating of the young.

The objective of the invention is the control of non-technological mode of physiological development of livestock, alarm about the presence of unhealthy animals, contributing to the timely prevention service personnel production facilities spread of diseases in semi-enclosed volume of the heated zone of the brooder, the ability to control behavior and physiological state of animals under the brooder during each cycle of abandonment (leaving) brooder flock. The invention uses the property of unhealthy animal inside heated areas of brooding over an extended period of time, whereas healthy animals almost simultaneously leave the zone heating for feeding and playing with each other.

As a result of use of the invention is the alarm from zone heating, if after some guaranteed time after the release of animals in this zone heating for feeding in the game it will be at least one animal.

The essence of the invention is illustrated figure 1 - 4.

Figure 1 shows a General view of den with piglets and placing the device on the way.

Figure 2 illustrates the method.

Figure 3 shows a General diagram of the device according to the method.

Figure 4 shows the timing chart of the operation of the device.

The implementation of the method is as follows. At time t1the output signal of element contacts the Olya, performed, for example, in the form of a capacitive sensor, falls below a predetermined threshold in the form of a signal matching a certain specific number of animals. Thus, registered the moment of abandonment (leaving) the overwhelming majority of animals heated brooder. Starts counting time (t2-t1), during which healthy animals are probably leave the zone heating for feeding or playing. At the end is control of the animal or animals in the area of heating during the time (t3-t2). If the specified threshold signal corresponding to the presence of somewhat less than one animal in the area surpassed, there is an alarm within a time frame of one cycle of feeding or games, until (t4-t3until the animals start to come back into the zone heated brooder. This alarm will indicate that at least one animal behaves as unhealthy. Thus, the employees can easily determine the specific disaster area among many in the workplace and to make culling unhealthy animal.

Device control and signaling the presence of unhealthy farm animals in the area contains a heating zone heating 1 brooder 2, animal presence sensor 3, the power source 4, the relay 5, and o is d power source 4 is connected to a first power input relay 5, it further comprises a signal lamp 6, a first amplifier 7, the first comparison circuit 8, the first unit 9, a timer 10, a pulse shaper 11, first and second differentiating circuits 12 and 13, the first managed key 14, the second comparison circuit 15, the second unit 16, the second managed key 17, and the output of the sensor of the presence of the animal 3 through the first amplifier 7 is connected with the first inputs of the first differential amplifier 8 and the first managed key 14, the output of which is connected to the first input of the second differential amplifier 15, the second input of which is connected to the output of the second knob 16, and its output is connected to the connection of the control input of the relay 5 and the second managed key 17, the first input connected to the output of the power source 4, the first output of the comparison circuit 8 through the first differentiating circuit 12 is connected with the control by the second input of the second controlled key 17 and counting the first input of the time counter 10, the output of which through the pulse shaper 11 is connected to control the second input of the first managed key 14 and through the second differentiating circuit 13 to boleosoma the second input of the time counter 10, and the output relay 5 is connected with a signal lamp 6.

On output the e first amplifier 7 is large in magnitude signal, corresponding to the presence in the zone of heating a large group of animals. However, this signal does not fall on the first inverting second input of the comparison circuit 14, since the first comparison circuit 8 (comparator) does not work and is in the initial state, the time counter 10 (phantastron or standby multivibrator) is not triggered, and the second control input of the first controlled switch (selector) 14 no enabling pulse (signal). At the output of the circuit element device 14 no signal (Uwyh=0), and the circuit 15 does not include the lamp 4 through cambiocorsa relay 5.

When a number of animals left the area heated brooder, the signal reinvestiruet (additionally marked “+”) the first input of the first differential amplifier 8 becomes less than the threshold at the output of the generator 9, the first comparison circuit 8 is activated (at time t1)starts the time counter 10 (time period (t2-t1)1), and in the end of the account at time t2) standby multivibrator 11 generates a pulse (t3-t2), which is sufficient for good control of the number of animals in the area. This pulse allows the signal on the number of animals to the inverting (additionally marked “-”) first and second input of the comparison circuit 15 for comparison with the specified maximum signal number is and unhealthy animals from the output of the second unit 16. Through cambiocorsa relay 5 is the alarm lamp 6 alarm. Lamp 6 informs staff about unhealthy animal in this zone heating until the time when most of the animals returned to the zone heating after feeding or games (time t4and when the first comparison circuit 8 returns to its original state. Negative front, its output signal is locked to the managed key 17, the relay 5 is unlocked, and the lamp 6 is extinguished. The time period (t4-t2) is essentially a time of alarm, during which automatically control the availability of unhealthy population in a particular zone heating. This is enough time for staff to receive information about-low-tech development of the young, began to carry out actions in the rejection of unfit animals.

The time counter 10 is ready for the next timing of the guaranteed output of livestock from the area of heat (t2-t1)11already at the time of the end control the presence of the animal in district heating (at time t3as it resets back-to-back output signal of the pulse shaper 11.

The beginning of the second feeding (second exit herd of heating zones for feeding or for games) is registered by the device in IOM is NT time t 5and further the device is still similar to that presented. The lack of animals in the zone of heating during the control does not cause alarm from the zone of heating.
