(54) CONSTITUTION FOR HEATING MANAGEMENT

     V.

The invention relates to rural households. in particular, to devices for heating pigs in pig-breeding industrial complexes ..,

There are known devices for controlling the heating of animals, which contain a temperature sensor, a temperature setter, connected to a controller, the output of which is connected to an energy source 1 mechanism.

A disadvantage of the known device is the low heating efficiency.

The closest in technical essence to the present invention is a device comprising a temperature sensor, a temperature setpoint device connected to a controller, the output of which is connected to an executive mechanism of a heat source 2.

However, this device is characterized by insufficient heating efficiency of the piglet due to the absence of blocks and connections that provide automatic control of the temperature regime of B ().

The purpose of the invention is to increase the efficiency of heating of the pigs by automatic

temporal temperature control.

The goal is achieved by the fact that it is equipped with a pulse generator, a timing unit, a BpeN HHoro mode setting unit, a switch and an indicator, the inputs of the counting unit being connected to the pulse generator and the time setting mode, the output of the timing unit connected to the input of the switch, B1 1 turns which are connected

with setpoint temperature and indikapfom.

- The drawing is a block diagram of yctpa C1BA.

The device contains 1 temdarature,

15 temperature setting device 2, connected to the controller 3, the output of which is connected to the heat source mechanism 5, unit 5, time counting 6, inputs connected to the pulse generator 7 and time mode setting unit 8, switch 9, the outputs of which are connected with indicator 10 and setpoint temperature 2 ..

The device works as follows.

Before switching on the heat source 5, the time set (the number of hours) corresponding to the time mode through which the temperature mode switches for increments is set using the time setpoint adjuster. Using the temperature setpoint 2, the voltages corresponding to the determined temperature values are set. heating is overpowered and temporally changing in time rhythm.

The principle of operation of the device is to maintain the set temperature with automatic switching of the settings of the controller 3 by changing the temperature mode of heating the pig. From the generator 7, the pulses go to a block of time counting, which is a variable divider frequency divider that generates pulses according to the ratio of the del-NIL installed on the setpoint 8 of a temporary mode. The duration of the pulses at the output of block 6 of the reference time corresponds. time in one, two, etc. days, depending on the established division koffshadenta. The pulses from the timing unit 6 are sent to the switch 9, which alternately changes the settings of the regulator 3, which are set using the temperature setpoint 2, at a predetermined time interval (day, two, etc.). At the same time, the number of the currently connected temperature mode is displayed on the indicator 10. In controller 3, the setpoint temperature from setpoint 2 is compared with the signal from temperature sensor 1 and the error signal is fed to the actuator. rabbit 4, which changes the radiation energy of the heat source 5 for as long as the signal;

the error does not become zero, the change in the time and temperature regimes, as well as the automatic regulation of the temperature ends after the last 5 modes have been tested. When the next group of piglets (after farrowing) arrives for heating, the device works in the same way.

Thus, the device increases the efficiency of heating by means of automatic regulation of the temporal temperature.
