Abstract

The utility model belongs to the technical fields of electronics and poultry hatching and relates to a chicken hatching sound-light reminding device. The chicken hatching sound-light reminding device consists of a direct-current power supply of 12 V, a sound pickup circuit, an audio signal primary amplification circuit, an audio signal secondary amplification circuit, and a sound-light reminding circuit. According to the chicken hatching sound-light reminding device, when no chicken is hatched in a hatching box, a microphone (MIC) can not pick up chicken sound signals, an NPN type transistor BG2 is not switched on, a buzzer HA does not make any sound and neither of light emitting diodes LED1-LED2 emit light. When a chicken is hatched, the MIC converts the sound of the chicken to an audio signal; and after the audio signal is amplified by an NPN type transistor BG1, the NPN type transistor BG2 is switched on, so that the light emitting diodes LED1-LED2 are lighted up, and the buzzer HA buzzes after being electrified.

Chick hatches the acousto-optic alarm set

Technical field

The utility model belongs to electronic technology and the poultry technical field of brooding, and relates to a kind of chick and hatches the acousto-optic alarm set.

Background technology

At present; Large-scale poultry hatching equipment wherein has a lot of not designs, installation chick to hatch the automatic alarm set of electronics; When chick hatches to 21 days left and right sides, though can concentrating relatively, chick hatches shell, in a single day chick goes out shell and must in time take out; Otherwise the incubation equipment gear train can influence the safety of chick, even can influence the survival of chick.And chick hatching always have an appointment 2～3% otherwise have slightly in advance or postpone out shell a little; Normal work period is also found than being easier to by day; If this situation occurs in night, the one, the chick that can go out shell is difficult in time taking out, and two can increase night attendants frequently checks and increases labour intensity.In order to improve and solve the generation of this situation, developing a kind of family chick, to hatch the automatic alarm set of electronics necessary.

Below specify this chick and hatch acousto-optic alarm set involved technology contents in manufacturing process.

The utility model content

Goal of the invention and beneficial effect: chick hatches the acousto-optic alarm set can in time find have chick to hatch in the incubator, can send sound and light signal immediately in case chick goes out the shell alarm set, reminds the staff in time the chick that hatches to be taken away.

The circuit working principle: when no chick hatched in the incubator, microphone MIC picked up the voice signal less than chick, not conducting of NPN transistor BG2, and hummer HA is sounding not, and LED 1～LED2 is all not luminous.When chick hatched, microphone MIC converted the tweeting sound of chick into sound signal, and sound signal makes NPN transistor BG2 conducting after NPN transistor BG1 amplifies, and LED 1～LED2 is lighted, and hummer HA gets and sounds a buzzer after electric.

Technical scheme: chick hatches the acousto-optic alarm set, is made up of 12V direct supply, pickup circuit and the elementary amplifying circuit of sound signal, sound signal second amplifying circuit, acousto-optic alert circuit, and its characteristic comprises:
