neither the triac regulator 10 at the time of the appearance of the front or the fall of the pulses delayed by the register 5. In this device, the front of the pulses from the output of the register 5 (Fig. 2e) of the control pulses of the h (Fig. 2n; Operator B. Pulse Shaper: performs the function of a logical differential device, similar in analog technology. When controlling a triac controller with 10 pulses from the output of register 5, it is impossible to control it according to a predetermined algorithm, since in this case the triac controller 10 will be turned on for a time equal to the pulse duration at the register 5 output.

The system works as follows.

Before the system starts operating, the program unit 1 uses the input / output unit 4, which is a set of button keys, and the display unit, to enter the code N. For example, the number 50 is chosen as the number 50, which will correspond to the beginning of dawn in the house. In the workflow. Systems pulses from a power supply unit 12, which converts a variable frequency of 50 Hz to a pulsating frequency of 100 Hz (Fig. 2a), are fed to an AND-HE element 7, converted to rectangular pulses (Fig. 25). They arrive at the counting input of the memory block 9, at the output of which the current code N appears, (50-0), proportional to the time, where (O). When the current code at the output of block 9 becomes equal to N | NJ, comparing indiscriminately with the code N. of the end of the night in block 1, the transition will take place to the dawn mode.

The transitions to the smooth dawn and dusk are created as follows.

Tota F (Fig. 2nd) to the controlled frequency divider 2, in which, when a certain code received from program block 1 and a clocked frequency from generator 8 is generated, the frequency F F is generated (Fig. 2e). The signal from the output of the divider 2 enters the l clock input shift register

5, and the pulses generated by the shaper of clock signals 13 arrive at its counting input (FIG. 2s, by the shift register 5, shifts the frequency by phase 41. the pulsating frequency coming from the shaper 13 of clock signals.

This shift corresponds to a certain delay time (shift).

Register 5 (Fig. 2 e) The signal is shifted to a certain phase up. , and clocked partly FO arrives at pulse generator 6, at the output of the latter a pulse appears at the leading edge of the shift register 5 (Fig. 2 g). This impulse arrives at the control input of the simistor regulator, while ensuring control of the voltage due to its inclusion in each half-period through time T in accordance with the phase (f. Defined by the code N. (Fig. 2). In accordance with with this, on the load, there will be a smooth dawn and a smooth sunset (Fig. 2).

Between the smooth dawn and dusk is the Day mode, which is determined by the end of the dawn (day start) M and the end of the day day (sunset start) N.J. During the day period, the code (M. 50) remains constant for some time (between N, j and KJ,). The triac regulator 10 is open for the entire half-period (Fig. 2L), and the maximum power is applied to the load (Fig. 2i).

The fixed memory unit 3 stores the annual lighting program of the poultry house. This matrix program is intended to be introduced into program block 1, for example, in the event of a voltage outage.

Example. The poultry house lighting control program (Fig. 3),

1. A total annual light program for 370 days is compiled. The value of the number of days in a cycle of 370 days is reduced to it. Each day the value of N will be subtracted from M; - the current day, and the difference between it DY enters the comparison element in the memory of block 1. If d, the program cycle repeats first and this will occur until the number of daily cycles (days) is equal to the annual cycle, i.e., AN 0, and the annual cycle is repeated.

2. Subprogram A of the daily cycle consists of subprograms: I Night, II Sunrise, III Day, IV Decline ie divides the day (24 hours) into 4 parts. Since the assumption is that every day of subroutine III the day will increase by 2 minutes due to the reduction of the subroutine 1 night, then in the cell of the current day IM is added 1 (this operation is performed in program block 1 (microprocessor). 1 min due to night reduction (increase in days), i.e., at kM time, and sunset will begin 1 minute later, due to an increase in days (shortening night), i.e. by time N, + uNj, where ftN is the night change step, and dN is the step of the day.

Thus, the duration of the day is gradually increased from 10 hours on the first day to 22 hours on the 370th day.

Moreover, the smooth dawn and sunset remain constant throughout the entire annual cycle and are 15 minutes each, according to the technology.

Subroutine I Night of the daily program A is implemented as follows.

From the time of the end of the night N., the current time M is subtracted (i.e. the night decreases). Then, the difference between S - NJ 4N - the step of changing the night goes to the element of comparison of microprocessor 1. If i N O, then the cycle of the program repeats first until uN O, then subtracted from the night code, M | night change step uN; (i.e. night will be reduced). Subroutine I Night then returns to the daily subprogram A II.

Subroutine II The dawn of the daily subprogram A is implemented as follows.

The end time of dawn N is reduced by the time of the current day N. Then this difference - the current dawn time arrives at the reference element. If odHp 0, then the power cell N code in the memory of microprocessor 1 is reduced by a step size of 4 N, and the program cycle is repeated for as long as. Then subroutine II returns

Dawn in the daily routine A III. And the next dawn will be earlier than the previous one by the value of uNp - the step of dawn change,

Subprogram III The day of the daily subprogram A is as follows.

From the end time, the current time N is subtracted. The difference between these values, q |) is compared by software block 1. If time lNj O, the cycle repeats first as long as d Nj O, then the change step Nj is added to the code of the day’s checks (i.e. the day will increase by l Nj ) and returns the routine to the daily cycle of subprogram A IV.

Subprogram IV The decline of the daily subprogram A is implemented as follows.

From the time of the end of the sunset, Нц, the current time of time N, is subtracted. Г The difference of these values, the current time of sunset, goes to the comparison element. If l M ,,, 0, the code of the power cell Nj is measured in a step of changing the power of the DM, this operation is performed in the microprocessor 1 and the Sunset subroutine repeats until O (i.e., the next sunset starts later on the value of d N-). Subprogram IV then returns to the daily cycle of subprogram A.

This device has a flexible scheme and provides a change in the annual cycle for various bird species, which increases the functionality of the system and expands the range of light control in closed-type houses.
