Egg freshness is fed back to user.
Accompanying drawing explanation
For clearer explanation present specification embodiment or technical scheme of the prior art, below by right
In the description of embodiment or prior art, the required accompanying drawing used is briefly described, it should be apparent that under,
Accompanying drawing during face describes is only to the reference of some embodiments in present specification, for those skilled in the art
From the point of view of, in the case of not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 shows that egg freshness distinguishes schematic flow sheet according to an embodiment of the invention.
Detailed description of the invention
Below in conjunction with embodiment, the present invention is described in further detail, but embodiments of the present invention do not limit
In this.
The present invention is determined as point of penetration with the freshness of egg, with intelligence egg carton as carrier, and fresh at egg
The method that the judgement upper employing time of degree adds up, shows with different states after arriving threshold values when timer
Out, being presented to the standing time of user's egg intuitively, specific embodiments is as follows:
A kind of discrimination system of egg freshness, it includes:
Whether photoswitch, have egg in being used for detecting egg carton, and the information detected passed to microcontroller
Device；And whether cover also by photoswitch detection egg carton lid lid, it is determined whether close egg freshness
Display lamp, to reach energy-saving effect.
Temperature sensor, is used for gathering ambient temperature, and the ambient temperature data collected is passed to micro-control
Device processed.
Microcontroller, in the case of having egg to put into, the timer in microcontroller starts timing, and
Described microcontroller is modified according to the varying environment temperature obtained, the parameter being added up timer, with
Obtain the most cumulative total time, judge the freshness of egg further according to this time.
WIFI module, is used for realizing microcontroller and server real-time Communication for Power, is believed by the egg in microcontroller
Breath data pass to server；Egg information data is transmitted mobile phone by server again, in order to egg checked by mobile phone
Information.
Further, thermistor temperature sensor is used to confirm ambient temperature.Temperature sensor uses negative
Temperature coefficient thermistor.Negative tempperature coefficient thermistor also known as NTC thermistor, be a quasi-resistance value with
A kind of sensor resistance that temperature increases and reduces.And by AD sampling module, temperature data is regularly adopted
Collection.
Timer in microcontroller can use the high accurate calculagraph of 16, and the precision of timing is 1ms, energy
The enough calculating well meeting egg standing time.
It is provided with on egg carton for indicating the most expired LED light of egg.Can be to eggs all in egg carton
Fresh state differentiates, and distinguishes with three kinds of colors of red, yellow, and green.
A kind of discriminating conduct of egg freshness, it includes:
) by photoswitch, environment is carried out light detection, scan egg carton, it is judged that in egg carton, whether have egg
Putting into, in the case of not having egg to put into, pass it to server, server is again by this information
Notify mobile phone APP；
) in the case of having detected that egg is put into, during timer；
) obtain ambient temperature by temperature sensor；
) according to the ambient temperature obtained, the time of timer is modified, according to the revised time
Egg freshness is judged；
) in the case of egg freshness state is unchanged, then return described step), timer continues
Timing；In the case of egg freshness state changes, carry out different colours by LED light and show；
) LED light carried out the information upload server that different colours shows；
) information got notifies mobile phone APP by server again.
Another embodiment: after program determines and places egg on intelligence egg carton, timer starts cumulative meter
Time.Meanwhile, the temperature sensor being newly added starts taken at regular intervals ambient temperature, according to different environment
Temperature, the parameter being added up timer is modified, as ambient temperature being divided into 5 grades, corresponding 5
Individual different cumulative coefficient, corresponding relation is as shown in table 1:
Table 1 ambient temperature and cumulative coefficient corresponding relation
| Temperature range | Accumulative parameter |
| 0℃-10℃ | 1 |
| 10℃-20℃ | 1.2 |
| 20℃-25℃ | 2 |
| 25℃-30℃ | 5 |
| > 30 degrees Celsius | 10 |
When intelligence egg carton is placed on the cold room of refrigerator or when southern winter is typically indoor, ambient temperature
Generally 0 DEG C-10 DEG C.Table in correspondence, cumulative coefficient now is 1, i.e. represents that egg is put at this temperature
The fresh keeping time put is month of acquiescence, and the status lamp of this egg position of intelligence egg carton is turned yellow color by green,
Status lamp after month this egg position is become red from yellow.
When intelligence egg carton in early summer time, be placed on general indoor, ambient temperature now is generally 20 DEG C-25 DEG C.
Cumulative coefficient now is 2, i.e. represents that the fresh keeping time that egg is placed at this temperature is month given tacit consent to
Half, i.e. during two weeks, the status lamp of this egg position of intelligence egg carton is turned yellow color by green, should after two weeks
The status lamp of egg position is become red from yellow.
User can be according to the prompting of egg tray, if yellow shows that this egg will expired eat as early as possible,
If warning light just represents this egg for red (mobile phone A PP and egg carton simultaneous display) and had preserved warp for a long time
Expired can not eat.APP and egg carton data syn-chronization, user can know in the very first time that egg is also surplus how many,
Whether there are expired egg and the egg that will pass by.
Egg carton records the quantity of put egg automatically, automatically identify egg freshness (fresh, common,
The state such as expired), and pass data to server, the smart terminal product such as mobile phone, flat board connects from server
Breath of collecting mail also is set up alternately by APP and user, and user can Real Time Observation egg carton state, in order to enter egg
Line pipe is managed.Position is empty, then feedback enters init state without egg signal, timer；On relaying
After egg, this position restarts to add up egg freshness.
The temperature and time that the present invention is kept by critesistor and the microcontroller detection egg of lower cost,
The freshness achieving egg judges, is conducive to the universal of the application of this technology and product.
In this specification, each embodiment uses the mode gone forward one by one to describe, and what each embodiment stressed is
With the difference of other embodiments, identical similar portion cross-reference between each embodiment.
" embodiment ", " another embodiment ", " embodiment " spoken of in this manual, etc.,
