Accompanying drawing explanation
The food spoilage based reminding method schematic flow sheet based on Smart Home that Fig. 1 provides for the present invention;
The food spoilage system for prompting structural representation based on Smart Home that Fig. 2 provides for the present invention.
Detailed description of the invention
Below in conjunction with the accompanying drawings and specific embodiment, it is further elucidated with the present invention.
Embodiment one
As it is shown in figure 1, the food spoilage based reminding method schematic flow sheet based on Smart Home that Fig. 1 provides for the present invention.Concrete, the present embodiment provides a kind of food spoilage based reminding method based on Smart Home, said method comprising the steps of:
101, by being positioned at the image of the photographic head described food lay down area of picked-up above food lay down area and being radioed to mobile terminal;
102, by described mobile terminal, the image of described food lay down area is analyzed, particularly as follows: extract food image and it is carried out degree of being consistent comparison to determine food species with built-in default food picture library;
103, described mobile terminal carries out corresponding timing according to food species, and when timing time reaches corresponding with this food species deteriorating time threshold value, sends the rotten prompting for this food species.
Wherein, described photographic head may be installed on ceiling, and described food lay down area is dining table;Described photographic head can also be arranged on refrigerator inside, and described food lay down area is refrigerator shelf.The present embodiment only describes with the former.
Concrete, described photographic head absorbs the image of described food lay down area, is then sent to set up with it mobile terminal of wireless connections relation by built-in radio function by the image of described food lay down area.
The image of described food lay down area is analyzed by described mobile terminal, first, described mobile terminal will extract described food image from the image of described food lay down area, the image of wherein said food lay down area includes other article on food, dining table surface and dining table, described mobile terminal rejects the image corresponding to other article on dining table surface and dining table from image, by the food Extraction of Image of reservation out.
Then, the food image extracted is carried out degree of being consistent comparison to determine food species with built-in default food picture library by described mobile terminal, concrete mode is: stores several food pictures in advance in the data base of described mobile terminal, is wherein all identified with food title on every food;Described food image is carried out degree of being consistent comparison with several food pictures respectively, when comparison go out described food image reach predetermined threshold value with any one food picture degree of being consistent time, it is determined that both are consistent, and draw the food title of described food image;Food title according to described food image carries out the determination of food species.Predetermined threshold value is set by engineer, and such as 90%.
nullSuch as,Set the food entitled S1 Sn of several food picture identification,Food image has 3,Correspond to respectively: green vegetable、Pork braised in brown sauce、Cooking shredded potato,Set comparison result and reach predetermined threshold value as green vegetable with S2 degree of being consistent,Pork braised in brown sauce reaches predetermined threshold value with S10 degree of being consistent,Cooking shredded potato reaches predetermined threshold value with S30 degree of being consistent,So,Then determine that green vegetable are consistent with S2、Pork braised in brown sauce is consistent with S10、Cooking shredded potato is consistent with S30,Show that the food title of described food image is respectively green vegetable、Pork braised in brown sauce、Cooking shredded potato,Then the food title according to described food image carries out the determination of food species,In reality,The division of food species can be carried out according to rotten duration,Such as the food that deteriorating time threshold value is 3 hours is divided into the first kind,By deteriorating time threshold value be 4 hours be divided into second species,By deteriorating time threshold value be 5 hours be divided into the third class,By that analogy,And the present invention only illustrates with the above-mentioned time,Reality does not limit it as 3 hours、4 hours、5 hours.
Then, described mobile terminal carries out corresponding timing according to food species, and when timing time reaches corresponding with this food species deteriorating time threshold value, sends the rotten prompting for this food species.
Such as, for green vegetable, setting it and belong to the first kind, the most described mobile terminal carries out timing to it and sends the rotten prompting for this food species timing time reaches 3 hours when, i.e. sends the rotten prompting for green vegetable to remind user not eat;For pork braised in brown sauce, setting it and belong to second species, the most described mobile terminal carries out timing to it and sends the rotten prompting for this food species timing time reaches 4 hours when, i.e. sends the rotten prompting for pork braised in brown sauce to remind user not eat;For cooking shredded potato, setting it and belong to the third class, the most described mobile terminal carries out timing to it and sends the rotten prompting for this food species timing time reaches 5 hours when, i.e. sends the rotten prompting for cooking shredded potato to remind user not eat.
Wherein, described method also includes: is obtained real time temperature by the temperature sensor being arranged on described photographic head and is radioed to mobile terminal;Described deteriorating time threshold value is determined by described mobile terminal according to real time temperature.In the present embodiment, described temperature sensing implement body by the temperature obtained above described food lay down area and is sent to mobile terminal by built-in radio function, and described mobile terminal is according to the different deteriorating time threshold value of the different set of temperature.Such as, when temperature is 10 degree, green vegetable are set, pork braised in brown sauce, deteriorating time threshold value that cooking shredded potato is corresponding are 8 hours, 9 hours, 10 hours;When temperature is 30 degree, green vegetable are set, pork braised in brown sauce, deteriorating time threshold value that cooking shredded potato is corresponding are 3 hours, 4 hours, 5 hours.
