Description
Technical field
The present invention relates to the technical field of auto alarm, more particularly, to a kind of children of automobile be detained warning device and
Its alarm method.
Background technology
There is a kind of in-car automatic alarm call-for-help device of infant's false-lock in the prior art, including PNP type triode Q1,
NPN type triode Q2, Q3, Q4, temperature controller, oxygen sensor, thermal infrared human inductor, phonetic alarm and loudspeaker, institute
The emitter stage for stating PNP type triode Q1 connects automobile storage battery positive pole, and base stage connects automobile storage battery negative pole and is grounded；The pole of positive-negative-positive three
Pipe Q1 colelctor electrode connects temperature controller, oxygen sensor, one end of thermal infrared human inductor respectively；The temperature controller, oxygen are passed
Sensor, the other end of thermal infrared human inductor connect NPN type triode Q2, Q3, Q4 base stage respectively；The NPN type triode
Q4 emitter stage concatenation phonetic alarm and loudspeaker.Due to using above-mentioned structure design, that is, pass through three inhomogeneous sensings
Device, can perceive and judge it is in-car whether someone produces danger because of high temperature or anoxic, while automatic alarm and being sent to outside
Call for help, succoured in time so that being stranded in-car infant.Such design sensor type is more, cost compared with
Height, and temperature oxygen these parameters are easily influenceed by external environment, so that the probability of warning device false alarm can be caused
It is higher.
The content of the invention
The present invention fills to overcome at least one defect described in above-mentioned prior art to be detained alarm there is provided a kind of children of automobile
Put, can effectively reduce the False Rate of detection means in warning device.
In order to solve the above technical problems, technical scheme is as follows：A kind of children of automobile is detained warning device, including
Detection unit, alarm unit and control chip, described detection unit connection control chip, described alarm unit connection control
Chip, described detection unit includes thermal infrared human inductor and position sensor.So as to effectively reduction warning device wrong report
Alert rate, and simplify the structure of warning device, reduce its cost.
Further, described alarm unit includes warning circuit, and described warning circuit includes buzzer and signal is sent out
Emitter, described buzzer and signal projector are in parallel.So as to ensure when detecting in-car and having children, the buzzing on car
The car owner of handheld mobile phone can also receive alarm signal, the effect of double shield alarm while device is reminded.
Further, connected in described warning circuit hand switch.So as to warning device once occur false alarm or
When person's time of fire alarming is long, car owner can be with manual-lock warning device.
Further, described signal projector includes crystal oscillating circuit, and described crystal oscillating circuit connects control chip, so that
Ensure that alarm can accurately be signaled to car owner's mobile phone.
Further, connected in described warning circuit overheat protector.So as to be effectively protected warning device, it is prevented
Burnt out because of overheat.
Further, connected in described warning circuit time switch.So as to when warning device detection is in-car without children
When, automatic disconnecting warning device reduces energy consumption.
A kind of children of automobile is detained the alarm method of warning device, comprises the following steps：S1：Car stops working, vehicle door locking；
S2：Detection unit is acted, and whether infrared sensor of the human body detection in-car has whether the thermal source in-car of position sensor detection simultaneously has
Object of which movement；S3：If infrared sensor of the human body and position sensor judge all to be yes in step S2 simultaneously, start alarm single
Member.This method process is simple, effectively the false alarm rate of reduction warning device.
Further, it is characterised in that when in step S2, infrared sensor of the human body do not detect in-car have thermal source or
When position sensor detection in-car does not have that there are objects moving, then do not start warning circuit.
Further, it is characterised in that start in step S3 after alarm unit, when car owner has found that in-car does not have children, car
Main to press hand switch, alarm stops.The long energy consumption of warning device time of fire alarming is also prevented from big, while can also warning device again
Manual-lock during false alarm.
Further, it is characterised in that the startup alarm unit described in step S3 is included to car owner's mobile phone sending signal
Sounded with buzzer.So as to ensure when detecting in-car and having children, hand-held hand while the boom unit on car is reminded
The car owner of machine can also receive alarm signal, the effect of double shield alarm.
Compared with prior art, beneficial effect is：Children of automobile is detained warning device compared with prior art, of the invention
Warning device structure is simpler, and required kind of sensor is less, so that significant portion cost has been saved, meanwhile, it is red using heat
The dual sense of outer human inductor and position sensor can effectively reduce warning device false alarm rate, improve alarm accurate
Property, and device is provided with hand switch, can avoiding device false alarm and the long-time alarm that produces.
Brief description of the drawings

Fig. 2 is overall control circuit diagram of the invention.
Fig. 3 is warning circuit schematic diagram of the present invention.
Fig. 4 is that children of automobile is detained warning device alarm flow figure.
Embodiment
Accompanying drawing being given for example only property explanation, it is impossible to be interpreted as the limitation to this patent；It is attached in order to more preferably illustrate the present embodiment
Scheme some parts to have omission, zoom in or out, do not represent the size of actual product；To those skilled in the art,
Some known features and its explanation may be omitted and will be understood by accompanying drawing.Being given for example only property of position relationship described in accompanying drawing
Explanation, it is impossible to be interpreted as the limitation to this patent.
As Figure 1-4, a kind of children of automobile is detained warning device, including detection unit, alarm unit and control chip,
Described detection unit connection control chip, described alarm unit connection control chip, it is red that described detection unit includes heat
Outer human inductor and position sensor.
Further, described alarm unit includes warning circuit, and described warning circuit includes buzzer and signal is sent out
Emitter, described buzzer and signal projector are in parallel.
Further, connected in described warning circuit hand switch.
Further, described signal projector includes crystal oscillating circuit, described crystal oscillating circuit connection control chip.
