Abstract

The invention relates to the field of agriculture, namely to means for automating the control of the operation of the mechanism for turning the incubator trays. The aim of the invention is to expand the functionality. When the incubator trays are turned, the end switch 2 is closed, after which the limit switch 3 is opened and the single potential from output 6 sets the trigger (TG) 5 to the zero state. The positive signal drop from the output 8 of the flip-flop 5 by means of the pulse former 10 and the disjunctor 11 sets the shift register (Cp) 13 to the zero state. When the trays are turned to the initial state, the switch 3 is closed and the switch 2 is opened. The TG 5 goes to the unit state, the Pulse from its output through the pulse former 9 and the disjunctor 11 is fed to the control input 12 Cp 13 and sets it to the zero state. In case of an accident of the mechanism of turning the switching chambers of the TG 5 and the zeroing of Cp 13, it does not occur and after the monitoring time expires, a high potential corresponding to the Alarm signal appears at the output of the latter connected to the signal bus 15. 2 Il.

The invention relates to agriculture, namely to means for automating the control of the operation of the mechanism for turning the incubator trays.

The aim of the invention is the expansion of functional capabilities.

FIG. 1 shows a block diagram of a device for monitoring the malfunction of the mechanism for turning the incubator trays; Q in FIG. 2 - timing charts of the device controlling the malfunction of the tray turning mechanism ..

The device contains a generator 1, two end; to switch 2 and -3, the output 4 of the first limit switch 2 is connected to the S-input of the trigger 5, the output 6 of the limit switch 3 - to the R-input of the trigger 5, direct and otherwise, the limit switch 3 is opened, and a single potential is formed at its output 6, which brings the trigger 5 to the zero state. The pulse shaper 10, by a positive signal differential from the inverse output 8 of the flip-flop 5, generates a pulse, which through the disjunctor 11 enters the control input 12 of the shift register 13 and sets it to the zero state.

The frequency divider 17 starts a new cycle of sequential recording of the unit information from the input 14 to the shift register 13. At the time tf, the incubator trays start to their initial state. Limit switch 3 closes. In the moment

Versa outputs 7 and 8 of which correspond to the time tj limit switch 2 times35

| are connected to the inputs of the formers 9 and 10 pulses, the outputs of which are connected to the inputs of the disjunctor 11, connected by the output to the input 12 of the installation in O - the shift register 25, the information input 14 of which is connected to the power bus, the signal bit to the signal 15, the synchronous input 16 of the shift register 13 is connected to the output of the jO frequency 17 body, the input of which is connected to the output of the generator 4.

The device works as follows;

I At time t, the limit switch 2 is open and the limit switch 2

 switch 3 is closed, at. In this case, at their outputs 4 and 6, respectively, E1 HIS and low potentials are present (Fig. 2). The trigger 5 is in a single state.

The pulses from the generator 1 are fed to a frequency divider 17, which, using their clock pulses, sequentially record single information from input 14 to the shift register 13. The division factor of the frequency divider 17 determines the control accuracy ul: the period of rotation of the trays T1, and the number of bits of the shift register 13 - the time interval to control the rotation of the trays T, and TC / - T1.

With proper equipment at time tj, the incubator trays start turning. The switch 2 closes 55 and a zero potential is formed at its output 4. At time tj, the turn of trays ends 40

it closes, a positive potential is formed at its output 4, which translates trigger 5 into a single state.

The pulse shaper 9, according to the positive signal differential from the direct output 7 of the flip-flop 5, generates a pulse, which through the disjunctor 11 is fed to the control input 12 of the shift register 13 and sets it to the zero state.

The frequency divider starts a new cycle of sequential recording of single information in the shift register 13, etc.

In the event of an accident of the mechanism of rotation of the trays at the end of time T1, the switching of the trigger 5 and the zeroing of the shift register 13 do not occur. After the monitoring time T has expired, a high potential appears at the output 15 of the shift register 13, corresponding to the Avariy signal, which is confirmed by subsequent clock pulses from the frequency divider 17.
