Description
Technical field
The invention belongs to safe early warning technical field, more specifically, it is related to a kind of the pre- of identification children false-lock in-car
Alert system.
Background technology
With increasing for automobile quantity, the popularization of family car is also more and more using related accident to vehicle.It is near several
Year, there are careless father and mother that in the car, forgetting baby is caused into reporting for work for infant's unexpected death all over the world.Infant is only
From locking in car, due to not possessing sense of self-protection and ability, easily occur unexpected.Especially in summer, it is closed be exposed to the sun under,
In-car transient temperature is up to more than 60 degree.Because child development is not complete, the speed that its body temperature rises, internal water is lost more than into
Year, people was fast, and its respiratory system and temperature capacity are also not so good as adult, therefore in " boxcar " inner easily generation " thermoplegia ".It is this
Disease refers to that caused by high temperature body temperature regulatory function is lacked of proper care, internal excess calories savings, thus trigger nervous organ by
Damage, until dead.In addition, children are locked in alone overlong time in car, in-car oxygen causes body anoxic, caused after being depleted
Tragedy of death occurs.Passenger in the market protects system mainly for driver and adult-passenger, does not prevent
The device or system of false-lock in Carriage for baby.However, infant is reported in media again and again by the in-car lethal accident of false-lock in recent years.
Although probability of happening is not high, once occur that destructive destruction will be brought to the family of party.Therefore, it is necessary to cause use
The great attention of car father and mother, it is to avoid the generation of above-mentioned dangerous situation.
The content of the invention

And perform step (1.3)；If non-UNICOM, step (1.4) is performed；
(1.3), judge the state of transducing signal, if transducing signal state is " 0 ", perform step (1.5)；If sensing letter
Number state is " 1 ", then performs step (1.7)；
(1.4), judge the state of transducing signal, if transducing signal state is " 0 ", perform step (1.5)；If sensing letter
Number state is " 1 ", then performs step (1.6)；
(1.5) dormancy of bluetooth module 1, is kept, step (1.7) is then performed；
(1.6), microcontroller 1 sends open command, wakes up the UNICOM's early warning main frame of bluetooth module 1, then send biography to early warning main frame
Sensor signal, then perform step (1.7)；
(1.7), after the timer time, return to step (1.1).
2. a kind of early warning system for recognizing that children's false-lock is in-car according to claim 1, it is characterised in that described micro-control
The monitoring flow of device 2 processed is：
(2.1), judge between bluetooth module 1 and bluetooth module 2 whether UNICOM, if UNICOM, perform step (2.2)；If
Non- UNICOM, then perform step (2.3)；
(2.2), read and judge sensor signal, if sensor signal state is " 0 ", represents in-car without children, then perform step
Suddenly (2.10)；If sensor signal state is " 1 ", representing in-car has children, then performs step (2.4)；
(2.3), start the UNICOM's bluetooth module 1 of bluetooth module 2, then perform step (2.10)；
(2.4), microcontroller 2 is received after the transducing signal that bluetooth module 1 is sent by bluetooth module 2, performs step
(2.5)；
(2.5), microcontroller 2 reads and judges central controlled lock signal, if central controlled lock is in unlocking condition, performs step
(2.10)；If central controlled lock is in blocking, step (2.6) is performed；
(2.6), microcontroller 2 reads and judges starting switch ACC signals, if starting switch ACC is closed, represents automobile and has put out
Fire, and perform step (2.7)；If starting switch ACC is connected, represent inserted automobile key and go out, then perform step (2.10)；
(2.7), the output of microcontroller 2 central controlled lock unlocking instruction, central controlled lock unlocking signal line is connected by input/output module,
Unlocking operation is performed, step (2.8) is then performed；
(2.8), microcontroller 2 reads and judges car door signal, car door signal line states is read, if all closing of the doors, hold
Row step (2.9)；If there is car door opening, step (2.10) is performed；
(2.9), the early warning of microcontroller 2 starts the double sudden strains of a muscle of output, audible warning, by input/output module, connects double flashing lights and loudspeaker
Signal wire, carries out sound and light alarm, then perform step (2.10)；
(2.10), after the timer time, return to step (2.1).
