Accompanying drawing explanation
Fig. 1 is system composition structural representation of the present invention;
Fig. 2 is food freshness area schematic of the present invention;
Fig. 3 is that flow chart is reminded in refrigerator food segmentation of the present invention.
The specific embodiment
As shown in Figure 1, in the present embodiment, a kind of composition of refrigerator food freshness segmentation system for prompting comprises: sensor assembly, control module, display module, alarm module and key-press module;
Sensor assembly is used for obtaining the general volatile alkali nitrogen content value of cold compartment of refrigerator and/or the indoor food of refrigerator freezing, and sends to control module;
Key-press module is set respectively the general volatile alkali nitrogen critical value of different stage for the different general volatile alkali nitrogen content value of food; As shown in Figure 2, food, in storing process, can carry out classification according to freshness.In the present embodiment, key-press module is set respectively three general volatile alkali nitrogen critical value critical value N1, N2 and N3, and form respectively four fresh regions by three general volatile alkali nitrogen critical value critical values and be followed successively by one-level fresh [0, N1], the fresh (N1 of secondary, N2], suspect food (N2, N3] and putrid and deteriorated (N3 ,+∞); The content value of the general volatile alkali nitrogen of normal food refers to the content value of the general volatile alkali nitrogen of meat product, and three general volatile alkali nitrogen critical value N1, the N2 and the N3 that set are respectively: 15mg/100g, 25mg/100g and 30mg/100g.
Control module receives general volatile alkali nitrogen content value and compares with the general volatile alkali nitrogen critical value of different stage, judges the level signal between general volatile alkali nitrogen content value each general volatile alkali nitrogen critical value of living in and sends to display module and alarm module; In the present embodiment, the general volatile alkali nitrogen content value in refrigerator and three general volatile alkali nitrogen critical value N1, N2 and N3 are compared, judge in food residing level signal in four fresh regions; For example, in the time that the general volatile alkali nitrogen of meat product in storing process is less than 15mg/100g, judge that meat product is that one-level is fresh, sends to display module by one stage signal; When general volatile alkali nitrogen is during at 15-25mg/100g, judge that meat product is that secondary is fresh, sends to display module by second signal; When general volatile alkali nitrogen is during at 26-30mg/100g, judge that meat product is suspect food, send three grades of signals to display module and alarm module is pointed out and alarm; In the time that general volatile alkali nitrogen is greater than 30mg/100g, judge that meat product is putrid and deteriorated, transmission level Four signal is to display module and alarm module is pointed out and alarm.
Style of writing word or the icon prompting of going forward side by side of display module receiver stage level signal, thus facilitate user to understand food fresh keeping situation; For example, food in the fresh region of one-level prompting " safe to eat ", in the fresh region of secondary prompting " edible " ", in suspect food region prompting " not advising eating " and in putrid and deteriorated region prompting " definitely can not eat ";
Alarm module receiver stage level signal and be positioned in level signal (N2, N3] and carry out refrigerator phonetic warning and/or light warning warning and/or SMS warning when (N3 ,+∞) freshness region.In the present embodiment, when meat product during in suspect food stage or putrid and deteriorated stage just by variety of way call user's attention edible safety.
In concrete enforcement, the content value of general volatile alkali nitrogen is also relevant with temperature and memory time in cold compartment of refrigerator or refrigerating chamber, temperature is lower, the content value of general volatile alkali nitrogen is lower, and memory time is longer, the content value of general volatile alkali nitrogen is higher, therefore system can directly judge the freshness of food according to the temperature in memory time and refrigerator compartment, a kind of refrigerator that adopts above refrigerator food freshness segmentation system for prompting, in running, can also leave temperature and the memory time in refrigerator according to the meat of table one, carrying out the segmentation of food freshness reminds:
The relation table of table one, refrigerator temperature and memory time and food freshness
| Freshness | The time of 0-4 ℃ of storage | The time of-18 ℃ of storages | Processing mode |
| One-level freshness | 0-3 days | 0-3 month | Safe to eat |
| Secondary freshness | 3-6 days | 3-6 month | Edible |
| Suspect food | 6-10 days | 6-12 month | Do not advise eating |
| Putrid and deteriorated | After 10 days | After 12 months | Definitely can not eat |
Specific works flow process as shown in Figure 3, in the time that food deposits refrigerator in, user arranges its of initial value by key-press module memory time, system according to internal clock signal and memory time initial value cumulative sum obtain storage total time T, and compare with preset time t1, t2 and t3, comparative result is prompted to user, and concrete steps are:
A) in the time of T≤t1, this food of system prompt " safe to eat ";
B) in the time of t1 < T≤t2, this food of system prompt " edible ";
C), in the time of t2 < T≤t3, this food of system prompt " does not advise eating ";
D) in the time of T > t3, this food of system prompt " definitely can not eat ".
When under the environment temperature of refrigerating chamber 0-4 ℃, when storage total time T is less than or equal to t1=3 days, system default food is that one-level is fresh, prompting user " safe to eat "; In the time that storage total time T is less than or equal to t2=6 days, system default food is that secondary is fresh, prompting user " edible "; In the time that storage total time T is less than or equal to t3=10 days, system default food is suspect food, and prompting user " does not advise eating "; In the time that storage total time T is greater than t3=10 days, system default food is putrid and deteriorated, and prompting user " definitely can not eat ".
And when refrigerating chamber is under the environment temperature of-18 ℃, when storage total time T is less than or equal to t1=3 month, system default food is that one-level is fresh, prompting user " safe to eat "; In the time that storage total time T is less than or equal to t2=6 month, system default food is that secondary is fresh, prompting user " edible "; In the time that storage total time T is less than or equal to t3=12 month, system default food is suspect food, and prompting user " does not advise eating "; In the time that storage total time T is greater than t3=12 month, system default food is putrid and deteriorated, and prompting user " definitely can not eat ", and then reaches segmentation prompting function.
