VII) information got notifies cell phone application by server again.
Compared with prior art, one of beneficial effects of the present invention are：
The discrimination system and method for a kind of egg freshness of the present invention, it uses temperature sensor to keep environment to egg
Temperature carries out periodic detection, then the relation by temperature and time, so as in time, accurately feed back to egg freshness
User.
Brief description of the drawings
, below will be to embodiment for clearer explanation present specification embodiment or technical scheme of the prior art
Or the required accompanying drawing used is briefly described in the description of prior art, it should be apparent that, drawings in the following description are only
It is the reference to some embodiments in present specification, for those skilled in the art, is not paying creative work
In the case of, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 shows that egg freshness according to an embodiment of the invention distinguishes schematic flow sheet.
Embodiment
The present invention is described in further detail with reference to embodiment, but the implementation of the present invention is not limited to this.
The present invention with the freshness of egg is determined as point of penetration, using intelligent egg carton as carrier, sentences in the freshness of egg
The fixed upper method to be added up using the time, is come out with different status displays after reaching threshold values when timer, intuitively showed
It is as follows to the standing time of user's egg, specific embodiment：
A kind of discrimination system of egg freshness, it includes：
Optoelectronic switch, for detecting whether have egg in egg carton, and by the information transmission detected to microcontroller；And
Also it can detect whether egg carton lid lid covers by optoelectronic switch, it is determined whether egg freshness display lamp is closed, to reach energy-conservation
Effect.
Temperature sensor, microcontroller is passed to for gathering environment temperature, and by the ambient temperature data collected.
Microcontroller, in the case where there is egg to be put into, the timer in microcontroller starts timing, and the micro-control
Device processed is modified to the parameter that timer adds up according to obtained varying environment temperature, during obtaining cumulative total of dynamic
Between, the freshness of egg is judged further according to the time.
WIFI module, for realizing microcontroller and server real-time Communication for Power, by the egg information data in microcontroller
Pass to server；Egg information data is transmitted mobile phone by server again, so that mobile phone checks egg information.
Further, environment temperature is confirmed using thermistor temperature sensor.Temperature sensor uses negative temperature system
Number thermistor.Negative tempperature coefficient thermistor is also known as NTC thermistor, one that to be a kind of resistance value increase and reduce with temperature
Kind sensor resistance.And temperature data is regularly gathered by AD sampling modules.
Timer in microcontroller can use the high accurate calculagraph of 16, and the precision of timing is 1ms, be can be good at
Meet the calculating of egg standing time.
The LED light whether expired for indicating egg is provided with egg carton.Can be to the fresh shape of all eggs in egg carton
State differentiated, and is distinguished with three kinds of colors of red, yellow, and green.
A kind of discriminating conduct of egg freshness, it includes：
I) by optoelectronic switch to environment carry out light detection, scan egg carton, judge whether there is egg to be put into egg carton, do not having
Have in the case that egg is put into, pass it to server, the information is notified cell phone application by server again；
II) in the case where having detected that egg is put into, during timer；
III) environment temperature obtained by temperature sensor；
IV) according to the environment temperature of acquisition, the time of timer is modified, it is new according to revised time on chicken egg
Freshness is judged；
V) in the case of egg freshness state is unchanged, then return to the step II), timer continues timing；
In the case of egg freshness state change, different colours are carried out by LED light and shown；
VI) by the information upload server that shows of LED light progress different colours；
VII) information got notifies cell phone application by server again.
Another embodiment：After program is determined, and egg is being placed on intelligent egg carton, timer starts cumulative timing.With this
Meanwhile the temperature sensor newly added starts taken at regular intervals environment temperature, according to different environment temperatures, timer is added up
Parameter be modified, environment temperature is such as divided into 5 grades, corresponding 5 different cumulative coefficients, the corresponding relation such as institute of table 1
Show：
The environment temperature of table 1 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 intelligent egg carton be placed on refrigerator refrigerating chamber or it is typically indoor in southern winter when, environment temperature is generally
0℃-10℃.Corresponding upper table, cumulative coefficient now is 1, that is, represents that the fresh keeping time that egg is placed at this temperature is acquiescence
One month, the status lamp of the egg position of intelligent egg carton becomes yellow by green, after month egg position status lamp by
Yellow is changed into red.
When intelligent egg carton in early summer when, be placed on general interior, environment temperature now is generally 20 DEG C -25 DEG C.Now
Cumulative coefficient be 2, that is, represent the half of one month of fresh keeping time that egg at this temperature places for acquiescence, i.e. two weeks
The status lamp of the egg position of Shi Zhineng egg carton becomes yellow by green, and after two weeks, the status lamp of the egg position is changed into from yellow
It is red.
User can according to the prompting of egg tray, if yellow shows that the egg will be eaten as early as possible by expired, if
Warning light is that red (cell phone application and egg carton simultaneous display) just represents the egg and preserved and expired too long can not eat.APP
With egg carton data syn-chronization, user can know that egg is also surplus how many in the very first time, if having expired egg and i.e. will be past
Egg.
Egg carton records the quantity of put egg, the freshness (shape such as fresh, common, expired of automatic identification egg automatically
State), and server is passed data to, the smart terminal product such as mobile phone, flat board is from server receive information and by APP with using
Family establish interaction, user can Real Time Observation egg carton state, to be managed to egg.Position is sky, then feedback is believed without egg
Number, timer enters init state；After upper egg is relay, the position restarts to count egg freshness.
The present invention detects the temperature and time of egg holding by the thermistor and microcontroller of lower cost, realizes
The freshness of egg is judged, is advantageous to the technology using the popularization with product.
Each embodiment is described by the way of progressive in this specification, what each embodiment stressed be with it is other
The difference of embodiment, identical similar portion cross-reference between each embodiment.
