Specific implementation method
The present invention is further illustrated below in conjunction with drawings and Examples.
As shown in Figure 1 and Figure 2, the present invention includes one group of RFID tag and refrigerator food safety convenience instrument, wherein:
1) described one group of RFID tag, be can be under-26 ℃ of low temperature, wet environment the RFID tag of operate as normal, general RFID tag all can satisfy this requirement; The number of RFID tag can difference according to demand dispose arbitrarily, generally is advisable with about 20.
2) described refrigerator food safety convenience instrument comprises wireless communication module, information storage module, label read module, MIM message input module, display alarm module and central processing module; Central processing module is connected with wireless communication module, information storage module, label read module, MIM message input module and display alarm module respectively, one group of RFID tag respectively with the wireless connections of label read module.
Wireless communication module is used for and the PC communication, upgrades food database, and sends food security information to the user.The wireless network that uses can adopt mobile networks such as GSM/3G/GPRS, also can adopt wireless network card to link to each other with home computer, surfs the Net by home computer.By one of above dual mode, wireless communication module can both upgrade the food data library information, and according to predetermined mode, in modes such as note, Email, desktop promptings, informs user's food outdated information.Here adopt the GTM900B wireless communication module of Huawei, transmit to realize the GPRS/GSM mode.
Information storage module is used to store RFID tag information, food storage information and food database.In view of required memory capacity is very little, use the FLASH storage of big or small 16M to get final product.
The label read module is used for reading rfid tags information.This class card reader is very general, can adopt the EP3100 module for reading and writing of EP company.
MIM message input module is used to specify the pairing food classification of label, conveniently selects the classification of food and checks corresponding information.Employing has the touch panel of numerical key, directionkeys, cancel key, acknowledgement key, and such touch panel can be from choosing on the market.
The display alarm module is used for the central processing module result is fed back to the user, lists all expired food, and shows the expiration time and the relevant information of not out of date food.According to cost requirement, can adopt dissimilar display screens such as TFT/LCD/LED.In addition, can also add buzzer, when having food expired, sound a buzzer and remind the user.
Central processing module is used to handle the RFID tag information of reading in, and stores information into information storage module; Food database in the recalls information memory module shows on display screen, is user's storage time of offering suggestions; According to the selection and the current time of MIM message input module, store food storage information into information storage module; Control wireless messages module is carried out food database and is upgraded, and will upgrade the result and store information storage module into; Regularly detect information storage module,, judge the present food security situation automatically, make corresponding prompting according to wherein food storage information and food data library information.Realize such function, can adopt general embedded chip, as ARM922T, ARM10TDM1 etc., the software of above function is satisfied in customization, is written in the chip to get final product.
The refrigerator food safety convenience instrument can be embedded in the refrigerator as the part of refrigerator, also can use separately.
As shown in Figure 3, be refrigerator food safe-guard system workflow diagram of the present invention, its step is as follows:
1, uses a RFID tag, be fixed together with the food that will store.Here can take different fixing means according to the type difference of food.If fresh vegetables, fruit, can label is fixing with rubber band, cord etc.; If box-packed, dish dress food, then available adhesive label is glutinous thereon.
2, operative installations label read module, reading rfid tags information.REID need not contact, therefore opens the label read mode, label can be finished near device read.
3, operative installations MIM message input module is specified the kind of the corresponding food of this label.According to user key-press, device provides satisfactory food variety information on the display alarm module, if there is not corresponding kind then to be default class.Suggestion storage fate according to device provides confirm to adopt a proposal, or the fate of self-defined input is used in the cancellation suggestion.
4, food is in the storage link, and most times of device all are in this state.Central processing module can regularly call wireless communication module, adopts one of the above two kinds of means of communication, obtains the lastest imformation of food database, and stores information storage module into.The timing automatic detection food storage of central processing module database has judged whether that food is expired, if there is food expired, then enters next step and reminds the user, otherwise consistently maintain this stage.
5, expired when having detected food, central processing module is transferred to the display alarm module with food labelling information, food storage time and the outdated information of correspondence and is fed back to the user, and by wireless communication module with this information notification user.Show the food outdated information on the display screen, the buzzing of buzzer certain interval of time once, and by wireless telecommunications send SMS message, Email, desktop remind to the user.
Under general state, the user can pass through the refrigerator food safe-guard system, inquires about the information such as the time of putting into, expired time of every sample food, both can obtain by the device display screen, also can obtain by the wireless communication mode inquiry.
