the circuit of the chickling hatching announcer(2)
BM is as the audio sensor .It used to detect if there is any chickling hatching from the eggs.When the sound signal is not detected by BM.The mono-stable delay circuit is at the steady state.The pin-3 of IC outputs low level.K is released.The buzzer HA doesn't give a sound.When there is any chickling hatching from the eggs in the incubator.BM will convert the detected sound of the chickling into the electric signal.The signal is amplified by V1 and V2.Then it generates the triggering signal.The mono-stable trigger circuit is triggered to turn over.It turns to transient stability from steady state.The pin-3 of IC outputs high level from low level.K is conducted to pull in.The normally open contacts are connected.The buzzer HA gives out alarm sound.It informs the worker there are chicklings hatching from the eggs.

the alarm circuit of the blocked seed channel in seeding-machine (2)
The photoelectric sensor consists of HL3 and V1.It used to detect if there are seeds in the seed channel.When seeding,the seed passes through the optical path of the photoelectric sensor constantly.It breaks the optical path between HL3 and V1.The internal resistance is large.At this time,V2 is saturated to conduct.V3 is stopped.HL1 is not lighted.The pin-3 of IC1 outputs low level.The 1Hz multivibrator and 1kHz multivibrator are not working.B1 doesn't give a sound.When the seed channel is blocked or there are no seeds,the light of HL3 shines on V1.V1 is with the low resistivity.V2 is stopped.V3 is conducted.HL1 is lighted.
