All other embodiments, which can be obtained by a person skilled in the art without inventive step based on the embodiments of the present invention, are within the scope of protection of the present invention.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a refrigerator according to an embodiment of the present invention, where the refrigerator includes:
a cabinet 10 serving as a support structure of the refrigerator and having a plurality of storage compartments therein;
an RFID module 20 for reading tag information of the RFID tag; wherein the tag information comprises a light intensity signal and food material information;
the controller 30 is configured to:

and determining the target RFID label corresponding to the target light intensity signal as the RFID label stored in the target storage room.
It is worth to be noted that the RFID tag according to the embodiment of the present invention has a light sensing function, and can detect a light intensity signal. The RFID tag can be directly attached to the surface of the food material, or can be placed in a device such as a clamp and attached to the food material to mark the food material.
The RFID module 20 comprises RFID antennas, the RFID antennas are arranged in the inner containers of the left side wall and the right side wall of each storage room and electrically connected with the ultrahigh frequency RFID module, and emit radio frequency signals to communicate with the RFID tags.
In one embodiment, the food material positioning triggering condition is: when the doors of all the storage rooms are in a closed state, sequentially starting the lighting devices in all the storage rooms; wherein when the lighting device is started in the current storage room, the lighting device is turned off in all the rest storage rooms; then, the target storage room is: the storage room in which the lighting device is started is recorded as a target storage room every time the lighting device of one storage room is started.
For example, when it is detected that the doors of all the storage rooms are in a closed state, the storage rooms are fully illuminated by means of the lighting devices, and the RFID tags located in the storage rooms can detect light intensity signals.
In another embodiment, the food material positioning trigger condition is: the door of any storage chamber is changed from a closed state to an open state; then, the target storage room is: the storage chamber of which the recording box door is changed from a closed state to an open state is taken as a target storage chamber.
For example, when it is detected that a door of any storage room is opened, the outside has illumination, so that the lighting device does not need to be controlled to start at this time, the storage room is fully filled with illumination in the mode of outside natural light, and the RFID tag in the storage room can detect a light intensity signal at this time; or, the refrigerator door is the same as the existing refrigerator in use principle, when the refrigerator door is opened, the lighting device of the refrigerator can be started, the storage room is fully filled with light by means of external natural light and the lighting device, and the RFID tag in the storage room can detect a light intensity signal.
After the target storage room is determined, the tag information of all the RFID tags is obtained, the RFID tags are screened, and the target light intensity signal of which the light intensity signal is greater than a preset light intensity threshold value in all the RFID tags is obtained, wherein the light intensity threshold value can be set to be 0. And determining the target RFID tag corresponding to the target light intensity signal as the RFID tag stored in the target storage room, wherein the target RFID tag stores food material information, and the food material information comprises a corresponding food material name, so that which food materials are stored in the target storage room can be determined at this time.
Further, when the doors of at least two target storage rooms are changed from a closed state to an open state, recording the state change time of the doors of the target storage rooms from the closed state to the open state; then, the controller is further configured to:

acquiring second light intensity signals of all the RFID tags again when the door of another target storage room is opened; wherein the door of the other target storage room is opened after the door of the current target storage room is opened;
-taking said first light intensity signal above said light intensity threshold as a first target light intensity signal and said second light intensity signal above said light intensity threshold as a second target light intensity signal;

deleting the same RFID tags as the first target RFID tags from the second target RFID tags corresponding to the second target light intensity signals, and determining the remaining second target RFID tags as the RFID tags stored in the other target storage room.
Illustratively, when the doors of the target storage room a and the target storage room B are opened successively, because there is a time difference when the doors are opened, the state change time when the doors of the target storage room a and the target storage room B are changed from the closed state to the opened state is recorded, and when the doors of the target storage room a are opened, there is illumination in the storage rooms, so that the first light intensity information of all the RFID tags can be obtained. Since there is a time difference between the opening times of the doors of the target storage room a and the target storage room B, there is a time difference between the acquired first light intensity signal and the acquired second light intensity signal, it should be noted that when the doors of the target storage room B are opened, it is required to ensure that the first light intensity signals of all the RFID tags are acquired. The first light intensity signal being greater than the light intensity threshold is taken as a first target light intensity signal and the second light intensity signal being greater than the light intensity threshold is taken as a second target light intensity signal. When the first light intensity information is acquired, the door of the target storage room B is not opened, and at the moment, a first target RFID label corresponding to the first target light intensity signal is determined as the RFID label stored in the target storage room A; when the second light intensity information is obtained, the doors of the target storage room a and the target storage room B are opened, at this time, the second target RFID tag corresponding to the second target light intensity signal includes the same RFID tag as the first target RFID tag, and needs to be deleted, and the remaining second target RFID tags are determined to be the RFID tags stored in the target storage room B.
Further, under the condition that all the doors of the storage room are closed, if some RFID tags still cannot confirm the storage room in which the RFID tags are located after the lighting device of the storage room is started for one round, the RFID tags may be shielded by food materials at this time, so that the detected light intensity information is 0, and the RFID tags may be marked to remind the user.
Compared with the prior art, the refrigerator disclosed by the embodiment of the invention utilizes the RFID tag with the photosensitive function, so that the RFID tag can be used for calibrating food materials on one hand, and recording the brightness change state by utilizing the photosensitive function on the other hand, and further judging which compartment the tag is stored in.

The RFID tag can be directly attached to the surface of the food material, or can be placed in a device such as a clamp and attached to the food material to mark the food material.
Specifically, in step S1, the two food material positioning triggering conditions are included, and the two food material positioning triggering conditions may be used together or independently.
In one embodiment, the food material positioning triggering condition is: when the doors of all the storage rooms are in a closed state, sequentially starting the lighting devices in all the storage rooms; wherein when the lighting device is started in the current storage room, the lighting device is turned off in the rest storage rooms; then, the target storage room is: the storage room in which the lighting device is started is recorded as a target storage room every time the lighting device of one storage room is started.
For example, when it is detected that the doors of all the storage rooms are in a closed state, the storage rooms are fully illuminated by means of the lighting devices, and the RFID tags located in the storage rooms can detect light intensity signals.
In another embodiment, the food material positioning trigger condition is: the door of any storage chamber is changed from a closed state to an open state; then, the target storage room is: the storage chamber of which the recording box door is changed from a closed state to an open state is taken as a target storage chamber.
For example, when it is detected that a door of any storage room is opened, the outside has illumination, so that the lighting device does not need to be controlled to start at this time, the storage room is fully filled with illumination in the mode of outside natural light, and the RFID tag in the storage room can detect a light intensity signal at this time; or, the refrigerator door is the same as the existing refrigerator using principle, when the refrigerator door is opened, the lighting device of the refrigerator can be started, the storage chamber is fully filled with light by means of external natural light and the lighting device, and the RFID tag in the storage chamber can detect the light intensity signal.
Specifically, in steps S2 to S4, after the target storage room is determined, tag information of all RFID tags is obtained, the RFID tags are screened, and a target light intensity signal of which the light intensity signal is greater than a preset light intensity threshold value is obtained from all RFID tags, wherein the light intensity threshold value may be set to 0. And determining the target RFID tag corresponding to the target light intensity signal as the RFID tag stored in the target storage room, wherein the target RFID tag stores food material information, and the food material information comprises a corresponding food material name, so that which food materials are stored in the target storage room can be determined at this time.
Further, when the doors of at least two target storage rooms are changed from a closed state to an open state, recording the state change time of the doors of the target storage rooms from the closed state to the open state; then, the refrigerator food material positioning method further comprises the following steps:
s101, acquiring first light intensity signals of all RFID labels when the door of a current target storage room is opened; the time difference between the acquisition time of the light intensity signal and the state change time is smaller than a preset time threshold;
s102, acquiring second light intensity signals of all the RFID labels again when the door of the other target storage room is opened; wherein the door of the other target storage room is opened after the door of the current target storage room is opened;

and S105, deleting the same RFID label as the first target RFID label from the second target RFID labels corresponding to the second target light intensity signals, and determining the remaining second target RFID labels as the RFID labels stored in the other target storage room.
Illustratively, when the doors of the target storage room a and the target storage room B are opened successively, because there is a time difference when the doors are opened, the state change time when the doors of the target storage room a and the target storage room B are changed from the closed state to the opened state is recorded, and when the doors of the target storage room a are opened, there is illumination in the storage rooms, so that the first light intensity information of all the RFID tags can be obtained. Since there is a time difference between the opening times of the doors of the target storage room a and the target storage room B, there is a time difference between the acquired first light intensity signal and the acquired second light intensity signal, it should be noted that when the doors of the target storage room B are opened, it is required to ensure that the first light intensity signals of all the RFID tags are acquired. The first light intensity signal being greater than the light intensity threshold is taken as a first target light intensity signal and the second light intensity signal being greater than the light intensity threshold is taken as a second target light intensity signal. When the first light intensity information is acquired, the door of the target storage room B is not opened, and at the moment, a first target RFID label corresponding to the first target light intensity signal is determined as the RFID label stored in the target storage room A; when the second light intensity information is obtained, the doors of the target storage room a and the target storage room B are opened, and at this time, a second target RFID tag corresponding to the second target light intensity signal includes an RFID tag identical to the first target RFID tag, and needs to be deleted, and the remaining second target RFID tags are determined to be the RFID tags stored in the target storage room B.
Further, under the condition that all the doors of the storage room are closed, if some RFID tags still cannot confirm the storage room in which the RFID tags are located after the lighting device of the storage room is started for one round, the RFID tags may be shielded by food materials at this time, so that the detected light intensity information is 0, and the RFID tags may be marked to remind the user.
