Brief description
Fig. 1 is the circuit diagram of Internet of Things outlet status alert circuit.
Specific embodiment
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely description is it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under the premise of making creative work
The every other embodiment being obtained, broadly falls into the scope of this utility model protection.
Refer to Fig. 1, in this utility model embodiment, a kind of Internet of Things outlet status alert circuit, including resistance R1, electricity
Hold C1, diode D1, audion VT1 and buzzer Y, described electric capacity C1 one end connects resistance R1 and plug B one end, electric capacity respectively
The C1 other end connects resistance R2, diode D2 negative pole and diode D1 positive pole respectively, diode D1 negative pole connect respectively resistance R3,
Diode D3 negative pole and diode D4 positive pole, diode D3 positive pole connects the resistance R3 other end, electric capacity C3 and audion VT1 respectively
Base stage, audion VT1 colelctor electrode connects resistance R2 and Shi Ji chip U1 pin 4 respectively, and the resistance R2 other end connects two poles respectively
Pipe D4 negative pole, electric capacity C5, resistance R4 and Shi Ji chip U1 pin 8, the resistance R4 other end connects resistance R5 and Shi Ji chip respectively
U1 pin 7, the resistance R5 other end connect respectively electric capacity C4, when base chip U1 pin 2 and Shi Ji chip U1 pin 6, when base chip
U1 pin 5 connect electric capacity C2, when base chip U1 pin 3 connect buzzer Y, it is another that the buzzer Y other end connects electric capacity C2 respectively
End, the electric capacity C5 other end, when base chip U1 pin 1, the electric capacity C4 other end, audion VT1 emitter stage, the electric capacity C3 other end, two
Pole pipe D2 positive pole and the plug B other end are simultaneously grounded；When described, base chip model is NE555；Described diode D2 is voltage stabilizing two pole
Pipe.
Operation principle of the present utility model is：Refer to Fig. 1, during use, plug B is inserted on Internet of Things socket, by electric capacity
Device C1 blood pressure lowering, diode D1 rectification, power after diode D2 voltage stabilizing, just come here electricity when, because electric capacity C3 both end voltage can not be mutated,
It is approximately 0 so that audion VT1 cut-off, general reset end 4 foot of NE555 is high potential, and the NE555 being connected into oscillating circuit starts
Vibration, makes buzzer Y sounding, informs that circuit is sent a telegram here, is constantly charged by R3 with C3, audion VT1 enters saturation,
The 4 foot step-downs of NE555, the blocking of oscillator, buzzer Y stops sounding.During power failure, electric capacity C3 passes through diode D4, R4, R5, C4
Rapid electric discharge, so C4 both end voltage reduces quickly, makes audion VT1 again end, and reset terminal 4 foot of NE5551 is changed into high electricity
Position, at this moment large bulk capacitance, C5 powers to oscillating circuit, makes buzzer Y sounding, informs line outage, when C5 is discharged to deficiency
When being vibrated with holding circuit, buzzer Y stop alarm.The resistance of adjustment resistance R3, when can change incoming call during the ring of buzzer Y
Between, the capacity of increase and decrease electric capacity C5, the ringing time of buzzer Y when can change power failure.Diode D4 can ensure have a power failure when C5 only to
Oscillating circuit is powered.
In sum, this utility model Internet of Things outlet status alert circuit, cooperation Internet of Things socket uses, in Internet of Things
When socket has a power failure and sends a telegram here, there is an of short duration caution sound, remind the working condition of people's socket, be convenient for people to use.
