In steps where there is logically no necessary causal relationship, the execution order of the steps is not limited to the execution order provided by the embodiments of the present application.
Fig. 2 shows a block diagram of an intelligent refrigerator according to an embodiment of the present application, fig. 3 shows a schematic diagram of an intelligent refrigerator, and a technical solution provided by an embodiment of the present application is described with reference to fig. 2 and fig. 3. The intelligent refrigerator comprises a processor 21, a Bluetooth receiving module 22, at least one information input device 23 and at least one preservation box 24, wherein:
each information input device 23 includes a device data processing unit 231, an information input device body 232, and a bluetooth transmission module 233; each information input device transmits the acquired food material basic information to the Bluetooth receiving module 22 through a Bluetooth broadcasting channel; each fresh box 24 comprises a fresh box data processing unit 241, a fresh box body 242, a weight sensor 243 and a Bluetooth transmitting module 244; each fresh-keeping box sends the obtained food material box-entering information to a Bluetooth receiving module through a Bluetooth broadcasting channel; the processor 21 performs matching according to the first weight information in the food material basic information and the second weight information in the food material in-box information received by the bluetooth receiving module 22, merges the food material basic information and the food material in-box information which are successfully matched, obtains food material management information, and updates the food material management library according to the food material management information.
The embodiment of the application has the following beneficial effects: the information input device responds to food material changing operation to obtain basic information (first weight information and food material attribute information) of the food material, and the intelligent refrigerator receives the basic information of the food material from the information input device through a Bluetooth broadcast channel; the weight sensor arranged on the fresh-keeping box responds to the food material feeding operation to obtain second weight information, and the intelligent refrigerator receives the food material feeding information (the second weight information and the identification information of the fresh-keeping box) from the fresh-keeping box through a Bluetooth broadcasting channel. And when the first weight information and the second weight information are successfully matched, merging the basic information of the food materials which are successfully matched with the food material in-box information to obtain food material management information, and updating the food material management library according to the food material management information. In the process, the information of the food materials is transmitted by utilizing a Bluetooth broadcast channel, so that the power consumption is low; the intelligent refrigerator can simultaneously receive basic information and box-in information of multiple groups of food materials, so that one-to-many food material management is realized; the weight change of the food materials is known, the changed position of the food materials stored in the preservation box can be determined, and intelligent food material management is realized.
For example, for each information input device, it acquires food material basic information in response to a food material changing operation, the food material basic information further including food material attribute information.
Wherein the food material changing operation is related to the type of the information input device. The information input device may be one or more of NFC (Near Field Communication ) device, camera, scanning head, TP (Touch Pad, touch screen) Touch device or keys. If the information input equipment is NFC equipment and the NFC equipment is arranged in the intelligent refrigerator, the food material changing operation is to open the refrigerator door; if the information input device is a TP touch device and the TP touch device is arranged outside the intelligent refrigerator door, the food material changing operation is that a user executes the information input operation on the TP touch device. The information input device in the above example may be provided inside or outside the intelligent refrigerator, and may be set according to actual needs.
After the basic information of the food material is acquired by the information input equipment, the Bluetooth transmitting module of the information input equipment is applied, and the information is sent to the Bluetooth receiving module of the main control board based on a Bluetooth broadcasting channel. By way of example, the Bluetooth broadcast channel used is 37/38/39, and broadcast information can be transmitted via these three channels. Because each Bluetooth transmitting module or Bluetooth receiving module is in a dormant state at ordinary times and is awakened when data transmission exists, the data transmission method is high in data reliability and low in power consumption.
In addition, the information input device is different, and the manner of obtaining the basic information of the food material is different. The food basic information of the information input device is obtained by any one of the following modes: NFC equipment scans radio frequency tags in or on food materials; or, the camera shoots package information of food materials and then identifies the package information; or the scanning head scans a two-dimensional code or a one-dimensional code arranged on the food; or, the TP touch device or the key responds to the information input operation of the user.
In a specific example, the food material basic information includes first weight information and food material attribute information. In general, the two-dimensional code or the one-dimensional code set on the food material covers the weight information of the food material, so that the first weight information is obtained by scanning the two-dimensional code or the one-dimensional code set on the food material by the scanning head. The material attribute information includes at least one of a name, a category, a date of manufacture, and a shelf life.
For each fresh-keeping box, the weight sensor arranged in the fresh-keeping box responds to the food material box-entering operation to obtain second weight information, and the box-entering information also comprises identification information of the corresponding fresh-keeping box.
Each preservation box comprises a preservation box data processing unit, a preservation box body, a weight sensor and a Bluetooth transmitting module. When a user puts food materials into the first fresh-keeping box, the weight sensor responds to the food material box-entering operation to obtain the weight of the food materials in the box, and the weight is represented by second weight information. The identification information (such as the number of the corresponding preservation box) of the first preservation box is obtained by the identification of the weight sensor arranged on the first preservation box and the corresponding relation between the preset weight sensor identification and the preset preservation box identification; or, the identification information of the first fresh-keeping box is determined by the data of the set flag bit of the Bluetooth transmitting module of the first fresh-keeping box.
For example, there are 6 fresh-keeping boxes, the marks of each fresh-keeping box are B1, B2, B3, B4, B5 and B6, a weight sensor is arranged at the bottom of each fresh-keeping box, the marks of each weight sensor are G1, G2, G3, G4, G5 and G6, and the corresponding relation between the preset weight sensor marks and the preset fresh-keeping box marks is that the obtained B1 corresponds to G1, B2 corresponds to G2, B3 corresponds to G3, B4 corresponds to G4, B5 corresponds to G5 and B6 corresponds to G6. Thus, if the second weight information acquired by G6 is the second weight information, it can be determined that the identification information of the first fresh-keeping box is B6. In addition, in the bluetooth transmitting module that every preservation box set up, can set up the zone bit and set up the identification information of corresponding preservation box at this bluetooth transmitting module and correspond, like this, can analyze the identification information of confirming first preservation box through the data of the zone bit that sets up of the bluetooth transmitting module of discernment first preservation box. Therefore, the position of the food material stored in the preservation box can be automatically obtained, and the consumption information of the food material can be detected in real time. In a specific example, fig. 4 shows a schematic diagram of a data format of a bluetooth broadcast channel, where set flag bits are broadcast data (food storage location and weight of food).
As above, the bluetooth receiving module is one and is arranged in the intelligent refrigerator and is in communication connection with the processor; the bluetooth emission module is a plurality of, and every fresh-keeping box all disposes a bluetooth emission module with every information input device. The Bluetooth receiving module continuously scans the broadcast channel, analyzes the received data when receiving the information sent by the Bluetooth transmitting module, and sends the analysis result to the processor of the refrigerator. Thus, the intelligent refrigerator receives the food basic information and the food material box entering information through the Bluetooth broadcasting channel.
The processor receives the food basic information from the information input device and the food material in-box information from the fresh-keeping box through the Bluetooth receiving module, matches according to the first weight information in the food basic information and the second weight information in the food material in-box information, fuses the successfully matched food basic information and the food material in-box information to obtain food material management information, and updates the food material management library according to the food material management information.
Next, a fusion process is performed on the food material basic information and the food material in-box information, and an exemplary condition of the fusion is a weight condition, for example, if the first weight information and the second weight information are successfully matched, the food material basic information and the food material in-box information can be fused to obtain the food material management information.
For example, if the weight difference between the first weight represented by the first weight information and the second weight represented by the second weight information is smaller than the preset weight threshold, it may be determined that the first weight information and the second weight information are successfully matched. For example, if the first weight information of the food material identified by the information input device is 500g, the second weight information of the food material measured by the weight sensor is 495g, the weight difference between the first weight information and the second weight information is 5g, and the weight difference is smaller than the preset weight threshold value of 50g, the first weight information and the second weight information can be determined to be the same food material, and information fusion can be performed to obtain food material management information.
In a specific example, the food material basic information is: milk, milk products and production dates 2022-4-30, and the shelf life is 90 days and 500g. The food material box entering information is as follows: 495g and No. B6 fresh-keeping box. Thus, the food management information obtained by fusion is: milk, milk products and production dates 2022-4-30, and the quality guarantee period is 90 days, 495g and a No. B6 preservation box.
In the above example, in order to determine that the food material corresponding to the first weight information and the food material corresponding to the second weight information are the same food material, weight information is applied as the matching condition. As an optional implementation manner, a camera may be disposed in the intelligent refrigerator or the refrigerator door, and used for shooting food materials, so as to analyze the shot image to determine the name of the food materials placed in the intelligent refrigerator or the refrigerator door, and match the name of the food materials in the basic information of the food materials, and when the matching is successful, the intelligent refrigerator or the refrigerator door can determine that the intelligent refrigerator and the food materials are the same food materials, and can perform information fusion to obtain the food material management information.
In the actual application process, the food material management also comprises management under the condition that the food material is taken out from the fresh-keeping box. In this case, each fresh-keeping box sends the obtained food material out-box information to the Bluetooth receiving module through the Bluetooth broadcasting channel, and the processor updates the food material management library according to the out-box information.
The processor determines that the fresh-keeping box with the obtained food material box-out information is a target fresh-keeping box, the target fresh-keeping box sends the obtained food material box-out information to the Bluetooth receiving module, the processor receives the food material box-out information through the Bluetooth receiving module, and updates the food material management library according to the identification information of the target fresh-keeping box contained in the food material box-out information and the food material attribute information of the taken food material in the target fresh-keeping box.
Specifically, the processor receives the box-out information from the target fresh-keeping box through a Bluetooth broadcast channel; the box discharging information is obtained by responding to food material box discharging operation through a weight sensor arranged on the target fresh-keeping box, and comprises third weight information and identification information of the target fresh-keeping box; and updating the food material management library by using the box outlet information.
After the weight sensor G3 detects the weight change of the target fresh-keeping box, for example, the changed third weight information is determined, and the identification information of the corresponding target fresh-keeping box is B3. Meanwhile, the attribute information of the food materials stored in the target fresh-keeping box is stored in the food material management library, so that the data of the corresponding food material management library can be updated according to the third weight information.
In the practical application process, two or more food materials may be present in one fresh-keeping box, so for each information input device, if the food material basic information acquired by the information input device corresponds to two or more food materials, the first weight information in the food material basic information is two or more, and the number of the first weight information is the same as the number of the food materials. For example, the information input device acquires the basic information of the food material of the milk and the basic information of the food material of the yoghurt in a very close time period (for example, in 1 minute).
For each preservation box, if the food material entering box information obtained by the preservation box corresponds to two or more food materials, the second weight information in the food material entering box information is two or more, and the number of the second weight information is the same as the number of the food materials. For example, the fresh-keeping box 1 acquires the information of milk entering the box and the information of yoghurt entering the box in a very close time period (for example, in 1 minute).
When the processor matches according to the received first weight information in the food basic information and the second weight information in the food material in-box information, if the matching is successful, the food material basic information and the food material in-box information which are successfully matched are fused to obtain at least one food material management information, and the food material management library is updated according to the at least one food material management information.
In this example, the food material management information of milk and the food material management information of yogurt are obtained. The processor further identifies weight information, fresh-keeping box identification information and food attribute information in the food management information; and updating the food material management library according to the weight information, the fresh-keeping box identification information and the food material attribute information.
Referring to fig. 5, an embodiment of the present application shows a fresh box comprising: fresh-keeping box data processing unit 51, fresh-keeping box body 52, weight sensor 53, bluetooth emission module 54 and power supply unit 55, weight sensor 53 sets up in fresh-keeping box bottom, wherein:
the weight sensor 53 generates second weight information in response to a user's food material in-box operation; the fresh box data processing unit 51 packages the second weight information and the identification information of the fresh box as the in-box information; the bluetooth transmitting module 54 transmits the in-box information to the bluetooth receiving module of the processor of the intelligent refrigerator through a bluetooth broadcast channel, so that the processor performs matching according to the first weight information and the second weight information in the received food material basic information, if the matching is successful, the matched food material basic information and the food material in-box information are fused to obtain food material management information, and the food material management library is updated according to the food material management information.
