Abstract
The invention relates to a refrigerator management system, in particular to a refrigerator management system based on a radio frequency identification technology, compressing a refrigerator, objects are stored in the refrigerator, and a display is arranged on the surface of the refrigerator. The refrigerator management system also comprises a radio frequency identification device and an infrared induction device, the radio frequency identification device is communicated with the display, the infrared induction device is arranged on the refrigerator and is connected with the display. The refrigerator management system has low cost and is simple to operate, is mainly used for data acquisition of storage equipment in public stadiums such as the refrigerator, a scientific and intelligent management system can be constructed by matching a background data management and analysis software.
Description
Technical field
The present invention relates to a kind of refrigerator management system, relate in particular to a kind of refrigerator management system that adopts REID.
Background technology
Refrigerator in the public domain of large stadiums such as Olympic Games display, need manage accurately the food of its inside, more because of its internal storage food variety and quantity, generally adopt bar code scanning, checking each time all needs food cleared carries out operation.Though the bar code scanning cost is low, its workload is big, and can not in time understand the freshness of food in the refrigerator.
RFID (Radio Frequency Identification) i.e. " radio RF recognition technology ", be a kind of contactless automatic identification technology, it adopts the noncontact mode by radiofrequency signal, automatically recognition objective object and obtain related data need not manual intervention.Wireless version as bar code, rfid system has the not available waterproof of bar code, antimagnetic, high temperature resistant, long service life, read that distance is big, data can encrypt, store that data capacity is big, the stored information change waits advantage freely on the label, can work in various adverse circumstances.It is used and just greatly reduces the logistics transportation of article and the expense of stock control, brings revolutionary variation for industries such as retail, logistics.
Summary of the invention
Technique effect of the present invention can overcome above-mentioned defective, and a kind of refrigerator management system based on REID is provided, and it is easy to use, and operating efficiency improves greatly.
For achieving the above object, the present invention adopts following technical scheme: system comprises refrigerator, stored article in the refrigerator, the refrigerator surface is provided with display, system also comprises rfid device, infrared inductor, rfid device is communicated by letter with display, and infrared inductor is arranged on the refrigerator, and is connected with display.
Carry out warm voice suggestion by infrared inductor to guest's presence with when leaving refrigerator, and on display, show.
Rfid device both can be arranged in the refrigerator, also can use separately.This device adopts the radio frequency reading technology, in real time refrigerator inside food is scanned management by rfid device, and the result that will scan is shown on the display screen, the user can determine whether that needs replenish certain based food according to the demonstration result, and can determine which food needs in time to change according to the food fresh keeping phase that shows.
Rfid device comprises RFID tag, card reader, memory, display module, alarm module, microprocessor, RFID tag is arranged on the article that store in the refrigerator, card reader, memory, display module, alarm module are electrically connected with microprocessor respectively, radio communication between RFID tag and the card reader.
Card reader, memory, display module wired connection respectively and between the microprocessor.
Card reader sends the radiofrequency signal of certain frequency by transmitting antenna, produces induced-current when radio-frequency identification card enters the transmitting antenna working region, and radio-frequency identification card obtains energy and is activated, and information such as self coding are sent by blocking built-in transmitting antenna; System's reception antenna receives the carrier signal of sending from radio-frequency identification card, be sent to card reader through the antenna adjustments device, card reader is carried out the demodulation sign indicating number to the signal that receives and is delivered to the backstage main system then and carry out relevant treatment, be stored in the user data conservation zone, by wired or the batch processing of 802.11b wireless communication protocol transfer of data be further analyzed processing to microprocessor at last.
Scanner can built-in one dimension or two-dimensional bar code laser scanning head, supports the scanning of all barcode types, and built-in high frequency or super high frequency radio frequency read write line have the data communication ability.RFID tag comprises food name, food quantity, puts into relevant informations such as time, freshness date, use the long-range radio-frequency identification label, as long as RFID tag is attached on the article of preserving in the refrigerator, when detecting article, all information of article can be presented on the display screen in real time at every turn.Alarm module comprises buzzer and vibrator, is convenient to manager works, and that vibrator is particularly suitable for is outdoor, the operation of noisy environment, and is expired or report to the police automatically when needing supplement quantity when food like this.Adopt radio-frequency technique that the food in the refrigerator is carried out real time scan, intelligent decision goes out the food that the client takes out or puts into, and makes screen scroll and shows and voice suggestion.
Pass through 802.11b communication protocol radio communication between memory and the microprocessor.Microprocessor adopts the LPC2210 model.
This device is the high-performance bar code data acquisition terminal that bar code scan, mobile computing and Infrared Wireless Communication technology are combined.Improved operating efficiency greatly.
Cost of the present invention is low, simple to operate, is mainly used in the data acquisition of memory devices such as public venue refrigerator; Cooperate back-end data management and analysis software can make up the management system of a cover science, intelligence.
Description of drawings
Below in conjunction with the drawings and specific embodiments the present invention is described in detail:
Fig. 1 is a circuit module schematic diagram of the present invention;
Fig. 2 is the module diagram of rfid device.
The specific embodiment
System comprises refrigerator, stored article in the refrigerator, and the refrigerator surface is provided with display, and system also comprises rfid device, infrared inductor, and rfid device is communicated by letter with display, and infrared inductor is arranged on the refrigerator, and is connected with display.
Rfid device comprises RFID tag, card reader, memory, display module, alarm module, microprocessor, RFID tag is arranged on the article that store in the refrigerator, card reader, memory, display module, alarm module are electrically connected with microprocessor respectively, radio communication between RFID tag and the card reader.Card reader, memory, display module wired connection respectively and between the microprocessor.Pass through 802.11b communication protocol radio communication between memory and the microprocessor.Alarm module comprises buzzer and vibrator.Microprocessor adopts the LPC2210 model.
Card reader identification automatically sticks on the RFID tag on the article in the refrigerator, and system shows the information of this tag storage on the display module of refrigerator display and rfid device.Understand stored number, the fresh-keeping degree of article in the refrigerator in real time.
Display module as with user's interaction platform, be used for the operation interface and the information of display system, comprise image, Chinese character, character, numeral etc.
The card reader reading rfid tags, if there is not the article shelf-life of this class article or preservation expired, alarm module sends the alarm signal.Without each each article of article go respectively search, also the keeper that need not tire out has felt dizzy, and both saves time, and saves human cost again, has also improved operating efficiency.
