The following describes a food management method using an example in which the RFID reader/writer 3 is connected to the display module. The specific food management method in which the RFID reader 3 is connected to the control module corresponds to the above method, and will not be described here again.
As shown in fig. 5 to 6, the food material management method of the refrigerator includes the steps of:
S1: acquiring temperature and humidity information of each storage space and RFID temperature and humidity electronic tags attached to food materials, and sending the temperature and humidity information to a display module;
Specifically, the method for acquiring the temperature and humidity information of the RFID temperature and humidity electronic tag attached to the food material specifically comprises the following steps:
S111: the food material is attached with an RFID temperature and humidity electronic tag and is placed in the storage space;
s112: the RFID antenna scans the RFID temperature and humidity electronic tag, reads the RFID temperature and humidity electronic tag information of the food material to acquire the temperature and humidity information of the environment where the food material is located, and sends the information to the display module through the RFID reader-writer 3.
Specifically, the RFID antenna acquires a radio frequency signal of the RFID temperature and humidity electronic tag, and sends the radio frequency signal to the RFID reader-writer 3; the RFID reader-writer 3 analyzes the obtained radio frequency signals and sends the temperature and humidity information acquired by the analyzed RFID temperature and humidity electronic tag to a display controller of the display module.
In the embodiment, i is used as a footmark to distinguish storage environment temperature and humidity binary group information (T si,Rsi) corresponding to different food materials; n represents the total number of food materials; the binary group information (T s1,Rs1)、(Ts2,Rs2)……(Tsi,Rsi)……(Tsn,Rsn) of the respective temperatures and humidities of the n kinds of food materials can be acquired through step S112.
In addition, the temperature and humidity information of each storage space is specifically obtained by: s12: the temperature and humidity sensor of each storage space collects temperature and humidity information of each storage space, and the control module sends the temperature and humidity information of each storage space to the display controller of the display module.
In this embodiment, j is used as a footmark to distinguish different storage spaces; m represents the total number of storage spaces; binary group information (T 1,R1)、(T2,R2)……(Tj,Rj)……(Tm,Rm) of the respective temperatures and humidities of the m storage spaces can be acquired through step S12.
S2: the display module is used for matching the temperature and humidity information of each storage space of the refrigerator with the temperature and humidity information of the read RFID temperature and humidity electronic tag; marking the storage positions of the food materials according to the matching result, and displaying the names of the food materials, the temperature and humidity of the current environment and the storage space for storing the food materials.
Specifically, the method comprises the following steps:
S21: i=i+1, where i is initially 0;
s22: and (3) taking the absolute value by taking the difference between T si and T 1,T2,……Tj……,Tm to obtain the I delta T 1|,|△T2|,……|△Tj|……|△Tm I.
And taking the absolute value by taking the difference between R si and R 1,R2,……Rj……,Rm to obtain the I delta R 1|,|△R2|,……|△Rj|……|△Rm I.
S23: the magnitude of |Δt 1|,|△T2|,……|△Tj|……|△Tm | is compared, and the magnitude of |Δr 1|,|△R2|,……|△Rj|……|△Rm | is compared to obtain the storage space temperature and humidity matching (T si,Rsi), and the storage space where the food material i is stored is determined based on this.
Specifically, the sizes of the |Δt 1|,|△T2|,……|△Tj|……|△Tm | are compared to obtain storage spaces corresponding to the |Δt| min and the |Δt| min, and the sizes of the |Δr 1|,|△R2|,……|△Rj|……|△Rm | are compared to obtain storage spaces corresponding to the |Δr| min and the |Δr| min;
When the storage space corresponding to the |Δt| min is the same as the storage space corresponding to the |Δr| min, the storage space in which the food is stored is determined to be the storage space corresponding to the |Δt| min or the |Δr| min. If the storage space corresponding to the |Δt| min and the storage space corresponding to the |Δr| min are both the refrigerating chamber 5, it is determined that the food material is stored in the refrigerating chamber 5.
When the storage space corresponding to the |Δt| min is different from the storage space corresponding to the |Δr| min, the storage space in which the food is stored is determined to be the storage space corresponding to the |Δt| min. Namely, when the storage space corresponding to the |DeltaT| min is different from the storage space corresponding to the |DeltaR| min, the storage space determined when the difference between the temperature detected by the RFID temperature and humidity electronic tag and the temperature value of the storage space is minimum is used as the storage space for determining the storage of the food. If the storage space corresponding to the |Δt| min is the refrigerating chamber 5 and the storage spaces corresponding to the |Δr| min are the first temperature changing drawers 81, and the storage spaces corresponding to the two are different, it is determined that the food material is stored in the refrigerating chamber 5.
More settings are made, when the storage space corresponding to the |DeltaT| min is a plurality of storage spaces, the storage space corresponding to the |DeltaR| min is only one storage space and is the same as one of the storage spaces corresponding to the |DeltaT| min, the storage space in which the food is stored is determined to be the storage space corresponding to the |DeltaR| min. For example, the storage space corresponding to the |Δt| min is provided with two storage spaces, namely the refrigerating chamber 5 and the first temperature changing drawer 81, and the storage spaces corresponding to the |Δr| min are all the first temperature changing drawer 81, so that the food materials are determined to be stored in the first temperature changing drawer 81.
When the number of storage spaces corresponding to the |Δt| min is plural, the number of storage spaces corresponding to the |Δr| min is only one and the number of storage spaces corresponding to the |Δt| min is different, the storage space with the smallest |Δr|corresponding to the number of storage spaces corresponding to the |Δt| min is determined as the storage space where food materials are stored. For example, the storage spaces corresponding to the |Δt| min are provided with two storage spaces, namely a refrigerating chamber 5 and a first temperature changing drawer 81, the storage spaces corresponding to the |Δr| min are all second temperature changing drawers 82, the first temperature changing drawer 81 is smaller in the difference between the humidity of the refrigerating chamber 5 and the first temperature changing drawer 81 and the humidity of the RFID temperature and humidity electronic tag on the food, and then the food is determined to be stored in the first temperature changing drawer 81.
When the number of storage spaces corresponding to the |Δr| min is one and the number of storage spaces corresponding to the |Δt| min is the same as one of the number of storage spaces corresponding to the |Δr| min, it is determined that the storage space in which the food is stored is the storage space corresponding to the |Δt| min. For example, the storage spaces corresponding to the |Δr| min are provided with two storage spaces, namely the refrigerating chamber 5 and the first temperature changing drawer 81, and the storage spaces corresponding to the |Δt| min are all the first temperature changing drawer 81, so that the food materials are determined to be stored in the first temperature changing drawer 81.
When the storage space corresponding to the |DeltaR| min is multiple, the storage space corresponding to the |DeltaT| min is only one and the storage spaces corresponding to the |DeltaR| min are different, the storage space for storing the food is determined to be the storage space corresponding to the |DeltaT| min. For example, the storage space corresponding to the |Δr| min is provided with two storage spaces, namely the refrigerating chamber 5 and the first temperature changing drawer 81, and the storage spaces corresponding to the |Δt| min are all the second temperature changing drawer 82, so that the food materials are determined to be stored in the second temperature changing drawer 82.
S24: marking a storage room where the food material i is placed according to the determination result;
s25: comparing i with the total number n of food material types, and judging that i is less than n? If yes, go to step S21; if not, the display screen displays the names of the food materials, the temperature and humidity of the current environment and the storage space.
In this embodiment, after the door is closed (the user completes the taking operation of food materials and labels), the operation of reading information by the RFID antenna is triggered; specifically, a position monitoring device is arranged on the refrigerator to send out a signal to trigger the food material management method of the invention when the refrigerator door is closed.
In this embodiment, temperature and humidity binary information of an environment where food is located is taken as an object to be compared with temperature and humidity binary information of each storage space, so as to obtain storage space binary information which is most matched with the temperature and humidity binary information of the environment where the food is located, and the storage space where the food is stored is determined according to the corresponding relationship between the storage space binary information and the storage space.
The present invention is not limited to the above-mentioned embodiments, and any equivalent embodiments which can be changed or modified by the technical content disclosed above can be applied to other fields, but any simple modification, equivalent changes and modification made to the above-mentioned embodiments according to the technical substance of the present invention without departing from the technical content of the present invention still belong to the protection scope of the technical solution of the present invention.
