It is static or walking states that system, which can detect vehicle by weighing pressure sensor and acceleration transducer,
And safety seat be used or be not used, such as non-walking states call in the following text weight pressure detecting safety seat be used and
More than after five minutes, system can issue information alert guardian by connection wireless device and need to check whether safety seat has just
It is using, and can be by data back to cloud, after the artificial detection to exception of cloud backstage, it can manual contact binding person guardian
Notice.Can not such as relate to guardian and binding person, system will alert process, avoid forgeing child and anticipate inside the vehicle
Outside.
In the acquisition and judgement of data, above-mentioned system, wherein the sensor for weighing can enter nobody by algorithm
The numerical value of seat positions 0g ± 5, at this time if will judge automatically after having object, weight of object to be greater than 5g above detecting to use
In, when acceleration transducer detects peak value and is greater than 0.5g, system is judged as normal walking states, is lower than 0.1g, system judgement
For stationary state.
Further, the system can also detect whether vehicle has a car accident by gravity sensor.If detecting generation
It can implement to position by gps module after traffic accident, data are then uploaded to by cloud by GPS and GPRS, staff will join
It is that binding person guardian alarms.
Data support aspect, and inductor used in the present invention detects that the data of acceleration are greater than 19.6m/s2 when it
When, system will be judged as improper shock, it will set out warning device, also, when weighing pressure sensor numerical value is greater than 5g
After will judge automatically in use.
This system can also further pass through built-in designed, designed operating system or third party's (Android, Ali's cloud etc.)
It is received and is realized to behaviour by aerial OTA (Over-the-Air Technology, over the air) by built-in with wireless module
Make system upgrade, promotes user experience.System built Bluetooth module with wireless device by being connected, when system judgement is wireless
Equipment apart from safety seat bluetooth module be more than ten meters of accidents apart from when can sound an alarm and reminded by mobile phone app automatically, with
Anti- child forgets onboard.
In system of the invention, this main power supply mode is used to power for replaceable lithium battery or by usb.
The present invention can be more timely, accurate and can comprehensively know vehicle inner ring by different sensors as a result,
The parameter in border determines system running state, and is prompted and alarmed when meeting preset trigger condition.Intelligence of the invention
Child safety seat system can effectively prevent parent to forget children in vehicle, and can also be according to traffic accident
Detection, accurately report accident or alarm.
Those of ordinary skill in the art will appreciate that: the foregoing is only a preferred embodiment of the present invention, and does not have to
In the limitation present invention, although the present invention is described in detail referring to the foregoing embodiments, for those skilled in the art
For, still can to foregoing embodiments record technical solution modify, or to part of technical characteristic into
Row equivalent replacement.All within the spirits and principles of the present invention, any modification, equivalent replacement, improvement and so on should all include
