Detailed Description
Based on the problems pointed out in the background art that the specific type and the valid period of food taken out of a refrigerator are difficult to be determined when a user takes the food from the refrigerator, and the food stored in the refrigerator is extremely easy to expire and difficult to manage, the invention provides an intelligent refrigerator management system, which aims to monitor the taking condition of an intelligent refrigerator based on a radio frequency identification technology, and can remind the storage condition of the currently taken storage object in real time when the user takes out a certain storage object from the intelligent refrigerator, so that the specific type and the remaining valid date of the storage object can be determined when the user performs the taking action, the situations that the user takes the storage object by mistake and uses the newly stored storage object to leave the long-term stored storage object are prevented, and the user is assisted to manage the service life of a large number of storage objects in the intelligent refrigerator.
As shown in fig. 1, the intelligent refrigerator management system of the invention comprises an intelligent refrigerator and a control terminal, wherein the intelligent refrigerator comprises a cabinet body 1, and a main control module, a communication module, an electronic reader 2 and a reminding module 3 which are arranged on the cabinet body 1. Wherein, the inside of the cabinet body 1 is provided with an accommodating space, the accommodating space is communicated with a refrigerating system of the intelligent refrigerator, and the internal temperature of the accommodating space can be regulated and controlled by the refrigerating system. The top of the cabinet body 1 is provided with an openable cabinet door 11, so that a user can open and close the cabinet door 11 to take and place stored materials in the cabinet. Each stored object is provided with an electronic tag, the electronic tag is associated with stored data such as the item information and the service life information (such as production date, quality guarantee period, and use limit date) of the stored object, and the electronic reader 2 is configured to be capable of reading the electronic signal intensity of the electronic tags of all the stored objects in the cabinet 1. Electronic reader 2, communication module and warning module 3 link to each other with host system respectively, and host system can be connected with control terminal communication through communication module, so that electronic reader 2 can carry out data transmission with control terminal based on communication module with the data transmission who reads to host system, so that host system can be with received data transmission to control terminal, and simultaneously, host system can also control and remind module 3 to start, send and remind information. Under the condition that the stored objects are not taken out of the intelligent refrigerator, the positions of all the stored objects are not changed, the distance between the electronic tag on each stored object and the electronic reader 2 is not changed, and the strength of the electronic signal of the electronic tag on each stored object in the refrigerator, which is read by the electronic reader 2, is basically stable and unchanged. When a user takes out a stored object from the intelligent refrigerator, the stored object is taken out of the cabinet 1, and in the process that the stored object moves out of the opening of the cabinet 1, the electronic tag on the stored object gradually leaves the reading range of the electronic reader 2, and the electronic signal strength of the electronic tag of the stored object read by the electronic reader 2 gradually weakens until the electronic signal strength is reduced to zero. During the movement of the taken and stored articles, the electronic reader 2 reads the electronic signal intensity of the electronic tags of all stored articles in the cabinet for multiple times and sends the read electronic signal intensity of the electronic tags of all stored articles to the main control module, and the main control module can send the received electronic signal intensity of the electronic tags of all stored articles to the control terminal through the communication module, so that the control terminal can monitor the change condition of the electronic signal intensity of the electronic tags of all stored articles in the cabinet 1, although when a certain stored article in the cabinet 1 is taken out, the electronic signal intensity of the electronic tags of adjacent stored articles may move due to the nearby vacant part of the accommodating space or be turned by a user and changed, the taken out stored article can be continuously moved to the outside of the cabinet 1 and moved out of the reading range of the electronic reader 2, so that when the control terminal monitors that the electronic signal intensity of the same electronic tag is continuously reduced and reduced to the reading range of the electronic reader 2 within a certain period of time When the time is zero, the electronic tag is proved to be moved out of the cabinet body 1, and the storage object where the electronic tag is located is the storage object which is taken out at present. In this case, the control terminal locks the electronic tag corresponding to the currently taken out storage object according to the characteristic that the electronic signal intensity is reduced to zero, retrieves the storage data associated with the electronic tag, and sends the retrieved storage data to the main control module through the communication module, so that the main control module can control the reminding module 3 to send the storage data, so that the intelligent refrigerator can detect the fetching action of the user when the user takes out a certain storage object from the cabinet body 1, and send a reminder to the user, so that the user can immediately know the specific storage data of the currently taken storage object, and the user can know the specific type and the remaining use date of the currently taken storage object in the fetching process.
In the above embodiment, the storage data of each storage is data stored in advance, and the change data such as the remaining effective date in the storage data is updated as the storage progress progresses after the first storage calculation. Those skilled in the art can set the specific information type included in the storage data according to the user requirement, as long as the storage data can embody the specific type and storage state of the storage object, and the user can determine whether the storage object meets the taking requirement according to the storage data, for example, the storage data may include the freezing time, the production place, the supplier, the quality, and the like in addition to the type information and the remaining effective date. The electronic tag and the stored data may be associated in any way, for example, an association is established between an electronic signal of the electronic tag and the stored data so as to call specific stored data by recognizing the electronic signal, or an association is established between unique tag information of the electronic tag and the stored data so as to call specific stored data by tag information of the electronic tag.
The electronic signal may be any radio frequency identification signal, such as an RFID signal, an NFC signal, or the like, and the electronic reader 2 is a reader capable of reading the radio frequency identification signal, for example, the electronic tag is an RFID tag, and the electronic reader 2 is an RFID reading device.
The control terminal is any control terminal capable of meeting the requirements of data transmission and data processing (such as data calculation, deletion or storage), for example, a cloud server or a hardware-form control device capable of being in communication connection with the intelligent refrigerator.
The mode of sending the stored data by the reminding module 3 can be any one or more reminding modes, for example, the reminding module 3 is a display module, and the mode of sending the stored data is to display the graphic and text information of the stored data, or the reminding module 3 is a voice module, and the mode of sending the stored data is to broadcast the stored data, or the reminding module 3 comprises a display unit and a voice broadcast unit, and the mode of sending the stored data is to broadcast the stored data while displaying the graphic and text information of the stored data.
In a possible embodiment, the stored data is calculated and stored based on basic data (product type, production date, shelf life, etc.) input by a user when storing the articles in the intelligent refrigerator, and the calculated stored data can establish an association relationship after the electronic reader 2 of the intelligent refrigerator reads the electronic tag of the stored article for the first time.
In a preferred embodiment, the calculation and storage of the stored data and the establishment of the association relationship between the stored data and the electronic tag are automatically processed when the intelligent refrigerator is put into the storage object. Specifically, the electronic reader 2 can also read the tag information of the electronic tags of all the stored objects in the cabinet 1, and the tag information at least includes the item information and the lifetime information (such as production date, expiration date, and expiration date) of the stored objects. After the tag information of the electronic tags of all the stored objects in the cabinet body 1 is read, the electronic reader 2 sends the read tag information of the electronic tags of all the stored objects to the main control module, the main control module can send the received tag information of the electronic tags of all the stored objects to the control terminal through the communication module, the control terminal can determine the tag information of the newly added stored objects in the cabinet according to the received tag information of the electronic tags of all the stored objects, the stored data of the newly added stored objects can be calculated according to the tag information of the electronic tags of the newly added stored objects in the cabinet, and then the tag information of the electronic tags of the newly added stored objects in the cabinet and the calculated stored data are stored in a correlation mode. When a user takes out the storage object from the cabinet body 1, the electronic reader 2 can read electronic signals of all electronic tags, tag information and signal strength corresponding to the read electronic signals are sent to the control terminal through the main control module and the communication module, the control terminal can lock the electronic tag of the taken out storage object according to the reduction condition of the signal strength, then storage data related to the tag information of the electronic tag can be taken out, and the main control module can transmit the taken out storage data to the reminding module 3 to remind the user of outputting.
