The address code consists of two parts: the incubator address code and the section address code. The number of controlled incubators 10 in the system is determined by the number of binary-decimal bits of the incubator address code, and the number of controlled sections 11 is determined by the number of bits of the section address code. The second mode is the control mode. This is the main mode of the system in which the control is performed. the current parameters of sections 11 of incubators 10 and the correct implementation of incubation regimes.

S, 13 the incoming code, with the address setting set at block 37, and in the case of a comparison (i.e., a call has occurred to this incubator), a single potential appears at the output of the comparison circuit 34. In addition, the communication unit 25 with the incubator control signal from the output 28 sets the data register 22 in parallel recording mode.

The address code of the section from the information outputs 19 of the register of the incubator's address 20 enters the second group of inputs 18 of the measuring unit 17 and connects the sensors of this section 11 for measurement.

The address code of the section is fed to the input 18 of the measurement unit 17 and then to the control inputs of the temperature switches 43, humidity 44, contact sensors 45 and connects to the switch outputs the corresponding temperature sensors 14, humidity 15 and contact sensors 13 of this section 11. The control signals formed by communication unit 25 with an incubator in the address recording mode, are fed through input 23 to counting input 46 of counter 47, which acts as a timer. After the end of the recording mode (i.e., a certain number has passed and a record has been written), a positive potential appears at the output of counter 47 and triggers a one-shot 50, which generates a trigger pulse and starts up analog-to-digital 5 converters 49 and 51 to information The inputs 52 and 53 of which are fed from the outputs 54 and 55 of the corresponding temperature switches 43 and humidity 44. Upon completion of the conversion, the analog-to-digital converter 49 generates a control signal. The end of the conversion, which is fed to the input 48 cell 47 and sets it to zero. At the information outputs of the analog-digital converters 49 and 51, a code of measured values of temperature, humidity, and at the input is formed.
