食材管理模组还可包括控制模块240和处理模块250。其中,控制模块240和处理模块250可独立于冰箱100的控制模块240和处理模块250,也可与冰箱100共用 控制模块240和处理模块250,处理模块250也可设置在云端。The ingredients management module may also include a control module 240 and a processing module 250 . Wherein, the control module 240 and the processing module 250 can be independent of the control module 240 and the processing module 250 of the refrigerator 100, and can also share the control module 240 and the processing module 250 with the refrigerator 100, and the processing module 250 can also be set in the cloud.
在本实施方式中,控制模块240可配置为控制射频读取模块230读取标识存取装置220内的射频标签211,处理模块250可配置为根据射频读取模块230读取到的标签信息获取标识件210的存取状态以及标识件210关联的食材信息,并可根据标识件210的存取状态管理食材存储列表。其中,食材存储列表可以通过显示屏102显示,通过食材存储列表可以获取冰箱100内存储的食材信息。In this embodiment, the control module 240 can be configured to control the radio frequency reading module 230 to read the radio frequency tag 211 in the identification access device 220, and the processing module 250 can be configured to obtain the tag information read by the radio frequency reading module 230 The access state of the identifier 210 and the food information associated with the identifier 210, and the food storage list can be managed according to the access status of the identifier 210. Wherein, the ingredient storage list can be displayed through the display screen 102, and the ingredient information stored in the refrigerator 100 can be acquired through the ingredient storage list.
射频标签211内可存储有编码信息,每个标签211可具有唯一对应的编码。冰箱食材管理模组200还可包括存储模块260,存储模块260中可存储有标识件210的编码,以及每个编码对应的食材信息,每个编码对应的食材信息即为其对应的标识件210关联的食材信息。同时,为了方便用户使用,可在标识件210上采用文字或者图示的方式示意其对应的食材信息。Coded information may be stored in the radio frequency tags 211, and each tag 211 may have a unique corresponding code. The refrigerator ingredient management module 200 may also include a storage module 260, which may store the codes of the identifiers 210 and the ingredient information corresponding to each code, and the ingredient information corresponding to each code is its corresponding identifier 210. Associated ingredient information. At the same time, for the convenience of the user, the identification member 210 may indicate its corresponding ingredient information in the form of text or illustration.
处理模块250在接收到射频读取模块230读取的标签211的编码后,可在存储模块260中查询是否存在对应的编码,以及该编码对应的食材信息,然后根据标识件210的存取状态判断该食材是否存储在冰箱100内部。当标识存取装置220中的标识件210的存取状态发生变化时,可认为冰箱100内存储的食材发生变化。After the processing module 250 receives the code of the tag 211 read by the radio frequency reading module 230, it can inquire whether there is a corresponding code in the storage module 260, and the food information corresponding to the code, and then according to the access status of the identification piece 210 It is judged whether the food is stored in the refrigerator 100 or not. When the access state of the identification piece 210 in the identification access device 220 changes, it can be considered that the food stored in the refrigerator 100 changes.
当然,存储模块260中也可仅存储预设的标识件210的编码,当射频读取模块230检测到用户从标识存取装置220中取出标识件210时,若存储模块260中未存储该标识件210对应的编码对应的食材信息,此时可通过显示屏102、语音模块或者手机等移动终端发出提示,提示用户自主输入食材信息并将用户输入的食材信息存储在存储模块260中。当检测到用户将该标识件210放回标识存取装置220内时,可将存储模块260中该标识件210的编码对应的食材信息删除。Of course, the storage module 260 can also only store the code of the preset identification piece 210. When the radio frequency reading module 230 detects that the user takes out the identification piece 210 from the identification access device 220, if the identification is not stored in the storage module 260 The material information corresponding to the code corresponding to the piece 210, at this time, a prompt can be sent through the display screen 102, voice module or mobile terminal such as a mobile phone, prompting the user to input the material information independently and storing the material information input by the user in the storage module 260. When it is detected that the user puts the identification piece 210 back into the identification access device 220 , the food material information corresponding to the code of the identification piece 210 in the storage module 260 can be deleted.
此外,标签211中存储的编码可为射频标签211生产制造时自带的编码,也可为后期写入的编码。为了提升传输效率,可在标签211中写入短编码,如01、02、03,如此,也便于存储模块260的管理以及批量生产。In addition, the code stored in the tag 211 can be the code that comes with the radio frequency tag 211 when it is manufactured, or it can be the code that is written later. In order to improve transmission efficiency, short codes, such as 01, 02, and 03, can be written in the label 211 , which is also convenient for the management and mass production of the storage module 260 .
具体示例如,在标识存取装置220中可存储有5个标识件210,5个标识件210的标签211编码可分别为01、02、03、04、05,存储模块260中可存储有每个编码对应的食材信息,如01-牛肉;02-鱼;03-苹果;04-青菜;05-牛奶。若射频读取模块230检测到标识存取装置220中放置的标签211的编码为01、03、04,则可将01、03、04对应的标识件210的存取状态标记为存入状态,02、05对应的标识件210的状态为取出状态。也就是可以认为用户取走了02、05对应的标识件210并将其附着在对应的食材上存放入了冰箱100内部,此时可以在食材存储列表中显示冰箱100 中存储有鱼和牛奶,如可在冰箱100显示屏102上在存储食材一栏显示02-鱼和05-牛奶。As a specific example, five identification pieces 210 can be stored in the identification access device 220, and the label 211 codes of the five identification pieces 210 can be respectively 01, 02, 03, 04, and 05, and the storage module 260 can store each The ingredient information corresponding to each code, such as 01-beef; 02-fish; 03-apple; 04-vegetables; 05-milk. If the radio frequency reading module 230 detects that the codes of the tags 211 placed in the identification access device 220 are 01, 03, and 04, the access state of the identification piece 210 corresponding to 01, 03, and 04 can be marked as the deposit state, The state of the identification piece 210 corresponding to 02 and 05 is the removal state. That is, it can be considered that the user has taken away the identification pieces 210 corresponding to 02 and 05 and attached them to the corresponding ingredients and stored them inside the refrigerator 100. At this time, it can be displayed in the ingredient storage list that fish and milk are stored in the refrigerator 100. For example, 02-fish and 05-milk can be displayed in the storage ingredients column on the display screen 102 of the refrigerator 100 .
在本发明一实施方式中,处理模块250还配置为若检测到第一预设时长内同一标识件210的存取状态变化次数大于或等于两次,则根据所述标识件210的最终存取状态管理食材存储列表。In one embodiment of the present invention, the processing module 250 is further configured to, if it is detected that the number of access state changes of the same identification piece 210 within the first preset time period is greater than or equal to two times, according to the final access status of the identification piece 210 State management ingredient storage list.
在本实施方式中,若在第一预设时长内检测到标识件210的存取状态多次变化,可判定此时可能存在异常情况,如可能用户从标识存取装置220取出或者存入标识件210的过程中遮挡其他标识件210的标签211导致未识别到,或者可能在使用过程中冰箱100门体101晃动或者标识存取装置220晃动使标识存取装置220内存取的标识件210跳动,导致射频读取模块230未能读取到标识件210的标签211,或者也可能用户取出部分食材或者查看食材时,食材上附着的标签211被误读。若根据标识件210的实际存取状态实时更新食材存储列表,会影响对应的食材信息存储情况的准确度,同时可能出现在短时间内食材存储列表中的同一标识件210对应的食材信息的存储信息不断变化,相应信息在显示屏102跳动或通过语音模块重复播报,容易给用户带来故障印象,影响用户体验。In this embodiment, if it is detected that the access state of the identification member 210 has changed multiple times within the first preset time period, it can be determined that there may be an abnormal situation at this time. Labels 211 that block other identification pieces 210 in the process of 210 are not identified, or the refrigerator 100 door 101 shakes or the identification access device 220 shakes during use, causing the identification pieces 210 accessed in the identification access device 220 to jump , causing the radio frequency reading module 230 to fail to read the label 211 of the identification piece 210, or the label 211 attached to the food may be misread when the user takes out some food or checks the food. If the ingredient storage list is updated in real time according to the actual access status of the identifier 210, the accuracy of the corresponding ingredient information storage situation will be affected, and at the same time, the ingredient information corresponding to the same identifier 210 in the ingredient storage list may be stored in a short period of time. The information is constantly changing, and the corresponding information jumps on the display screen 102 or is repeatedly broadcast through the voice module, which easily gives the user the impression of failure and affects the user experience.
进一步的,在本发明一实施方式中,控制模块240具体配置为:控制射频读取模块230以预设时间间隔读取标识存取装置220内的射频标签211;处理模块250配置为:接收到射频读取模块230读取的标签信息第二预设时长后根据标识件210的存取状态管理食材存储列表,其中,第一预设时长大于或等于预设时间间隔的两倍,第二预设时长大于或等于预设时间间隔的两倍。Further, in one embodiment of the present invention, the control module 240 is specifically configured to: control the radio frequency reading module 230 to read the radio frequency tag 211 in the identification access device 220 at a preset time interval; the processing module 250 is configured to: receive After the tag information read by the radio frequency reading module 230 is set for a second preset time period, the material storage list is managed according to the access state of the identification piece 210, wherein the first preset time length is greater than or equal to twice the preset time interval, and the second preset time length is twice as long as the preset time interval. Set the duration to be greater than or equal to twice the preset time interval.
在本实施方式中,射频读取模块230可以包括天线,且为了提升识别的准确度可以射频读取模块230可以包括双天线。标识存取装置220可以为安装在门体101门衬上的盒体,盒体可以沿门体101宽度方向延伸,双天线可以分别设置在盒体的两端,同步对标识存取装置220内的标识件210进行扫描,并在扫描后进行去重处理,去除两个天线重复扫描到的标签对应的编码。在运行过程中,射频读取模块230可保持持续工作,天线可从一侧向另一侧依次扫描,预设时间间隔可为天线完全一次扫描所需的时间,也就是对于同一标识件经预设时间间隔被天线扫描一次。当然,预设时间间隔也可为天线完全完成一次扫描后至再次启动天线扫描之间的时间间隔,或者天线两次启动时间之间的时间间隔。In this embodiment, the radio frequency reading module 230 may include an antenna, and in order to improve the accuracy of identification, the radio frequency reading module 230 may include dual antennas. The identification access device 220 can be a box body installed on the door lining of the door body 101, the box body can extend along the width direction of the door body 101, and the double antennas can be respectively arranged at both ends of the box body, synchronously to the identification access device 220. The identification piece 210 is scanned, and deduplication processing is performed after the scanning, and the codes corresponding to the tags repeatedly scanned by the two antennas are removed. During operation, the radio frequency reading module 230 can keep working continuously, and the antenna can scan sequentially from one side to the other, and the preset time interval can be the time required for the antenna to completely scan once, that is, for the same identifier Let the time interval be scanned once by the antenna. Of course, the preset time interval may also be a time interval between when the antenna completely completes one scan and when the antenna is started to scan again, or a time interval between when the antenna is started twice.
射频读取模块230读取的标签211信息可传输至处理模块250,处理模块250可对标签211信息进行处理并通过显示屏102显示。处理模块250在接收到射频读取 模块230读取的标签信息第二预设时长后再更新食材存储列表,如此,在两次更新食材存储列表之间的时间内,射频读取模块230至少能够读取两次标识存取装置220中标识件210的标签211,从而可以处理得到较为精准的信息,同时又可以尽可能的保证食材存储列表更新的时效性。The tag 211 information read by the radio frequency reading module 230 can be transmitted to the processing module 250 , and the processing module 250 can process the tag 211 information and display it on the display screen 102 . The processing module 250 updates the ingredient storage list after receiving the tag information read by the radio frequency reading module 230 for a second preset time period, so that during the time between updating the ingredient storage list twice, the radio frequency reading module 230 can at least The label 211 of the identification piece 210 in the identification access device 220 is read twice, so that more accurate information can be processed, and at the same time, the timeliness of updating the food storage list can be guaranteed as much as possible.
进一步的,在本发明一实施方式中,处理模块250具体配置为:Further, in an embodiment of the present invention, the processing module 250 is specifically configured as:
若在第一预设时长内标识件210的初始存取状态与最终存取状态相同,则保持食材存储列表中标识件210对应的食材信息不变。If the initial access status of the identifier 210 is the same as the final access status within the first preset time period, the food information corresponding to the marker 210 in the food storage list remains unchanged.
具体示例如,若在t1时刻检测到标签编码为01的标识件的存取状态为放入状态,在t2时刻检测到标签编码为01的标识件的存取状态为取出状态,而在t3时刻检测到标签编码为01的标识件的存取状态为存入状态,若t1至t3时刻的时间间隔小于第一预设时长,且t1和t3时刻标识件210的存取状态相同,也就是在第一预设时长内标识件210的初始存取状态和最终存取状态相同,则可认为在第一预设时长内标识件210的存取状态未发生变化,无需对食材存储列表中该标识件210关联的食材信息进行更新。For example, if it is detected at time t1 that the access state of the tag coded as 01 is the put-in state, at time t2 it is detected that the access state of the tag coded as 01 is the take-out state, and at time t3 It is detected that the access state of the identification piece whose tag code is 01 is the storage state, if the time interval from t1 to t3 is less than the first preset time length, and the access state of the identification piece 210 at the time t1 and t3 is the same, that is, in The initial access state of the identification piece 210 within the first preset time period is the same as the final access state, then it can be considered that the access state of the identification piece 210 has not changed within the first preset time period, and there is no need to modify the identification in the food storage list. The ingredient information associated with item 210 is updated.
进一步的,在本发明一实施方式中,处理模块250还配置为:Further, in an embodiment of the present invention, the processing module 250 is also configured to:
若在存储模块260中未查询到射频读取模块230读取到的编码信息,则将该标识件210标记为异常标识件210。If the coded information read by the radio frequency reading module 230 is not found in the storage module 260 , mark the identification piece 210 as an abnormal identification piece 210 .
在本实施方式中,若用户将其他带有射频标签211的物品放入标识存取装置220内,会产生扰乱信息,可能导致食材存储列表错乱。因此,当射频读取模块230读取到的编码信息未存储在存储模块260中时,可直接将该标识件210标记为异常标识件210,如可通过显示屏102等交互模块进行提示,同时,可直接在存储模块260中记录该标识件210为异常标识件210,不根据其更新食材存储列表。In this embodiment, if the user puts other items with radio frequency tags 211 into the identification access device 220, disturbing information will be generated, which may cause confusion in the food storage list. Therefore, when the coded information read by the radio frequency reading module 230 is not stored in the storage module 260, the identification piece 210 can be directly marked as an abnormal identification piece 210, as can be prompted through interactive modules such as the display screen 102, and at the same time , the identification piece 210 can be directly recorded in the storage module 260 as an abnormal identification piece 210, and the ingredient storage list is not updated according to it.
进一步的,在本发明一实施方式中,处理模块250还配置为:若射频读取模块230读取到的编码信息包括两个或两个以上的相同编码信息,则将两个或两个以上的相同编码对应的标识件210标记为异常标识件210。Further, in an embodiment of the present invention, the processing module 250 is further configured to: if the coded information read by the radio frequency reading module 230 includes two or more identical coded information, then the two or more The identification piece 210 corresponding to the same code is marked as an abnormal identification piece 210 .
在本实施方式中,为了保证食材管理模组的正常运行,每个标识件210中的编码为与其他标识件210的编码不同的单一编码,从而通过编码将不同食材进行区分。若射频读取模块230读取到两个相同的编码信息,则代表可能误将其他同类冰箱100上的标识件210放入标识存取装置220内,因此,为了避免食材信息混乱,可将两个标签编码相同的标识件210均标记为异常标识件210。In this embodiment, in order to ensure the normal operation of the food management module, the code in each identification piece 210 is a single code different from the codes of other identification pieces 210, so that different food materials can be distinguished by codes. If the radio frequency reading module 230 reads two identical coded information, it means that the identification piece 210 on other similar refrigerators 100 may be put into the identification access device 220 by mistake. The identification pieces 210 with the same label code are marked as abnormal identification pieces 210.
进一步的,在本发明一实施方式中,处理模块250还配置为:当标识件210的 存取状态由存入状态变化为取出状态时,记录标识件210的取出时间。Further, in one embodiment of the present invention, the processing module 250 is also configured to: when the access state of the identification piece 210 changes from the storage state to the withdrawal state, record the take-out time of the identification piece 210.
在本实施方式中,可在标识件210取出的时候记录取出时间,标识件210的取出时间可判定为标识件210对应的食材存入冰箱100的时间,如此,可以根据标识件210的取出时间记录对应的食材的存放时间。存储模块260中还可存储有食材对应的最佳存储时长,当检测到食材的存放时间达到最佳存储时长时,可控制发出相应的提示。当第一预设时间段内若检测到标识件210的存取状态变化两次或者两次以上,且初始存取状态和最终存取状态均为取出状态,则按照初始存取状态记录标识件210对应的取出时间。如此,能够避免异常状态导致对应的食材存放时间记录出错,进而导致当食材的实际存放时间达到最佳存储时长时,无法及时进行提示。In this embodiment, the take-out time can be recorded when the identification piece 210 is taken out, and the take-out time of the identification piece 210 can be determined as the time when the food material corresponding to the identification piece 210 is stored in the refrigerator 100. Record the storage time of the corresponding ingredients. The storage module 260 can also store the optimal storage time corresponding to the ingredients, and when it is detected that the storage time of the ingredients reaches the optimal storage time, it can control to issue a corresponding prompt. If within the first preset time period, it is detected that the access state of the identification piece 210 has changed twice or more than two times, and both the initial access state and the final access state are in the removal state, then the identification piece is recorded according to the initial access state. 210 corresponds to the take-out time. In this way, it is possible to avoid errors in the record of the storage time of the corresponding ingredients caused by the abnormal state, which will lead to failure to prompt in time when the actual storage time of the ingredients reaches the optimum storage time.
