Embodiment
Embodiment involved in the present invention is described in further details below in conjunction with the accompanying drawings.
With reference to Fig. 1 and Fig. 5, a kind of Internet of Things intelligent refrigerator, including main control module and from control module, main control module
Including core Slab element, RFID card reader unit, LCD touch screen unit, wired network adapter unit and wireless communication unit, from control
Module includes 51 single machine units, pressure sensor unit, temperature sensor unit and refrigeration for refrigerator blade unit, main control module
With carrying out data interaction from control module by serial ports.
System select based on using Intel XScale PXA270 core boards hardware development platform, the platform be with
The arm processor of Intel XScale frameworks.Embedded OS selects Windows CE 5.0.Windows CE are height
Modular embedded OS.
With the development of Internet of Things, the input of Internet of Things direction smart home is also expanding rapidly, the cost of RFID label tag
Also constantly reduce, may greatly substitute bar code to turn into food outsourcing.And RFID label tag is durable, lasting and non-maintaining with its
It is famous.
RFID card reader unit scan food labelling, RFID card reader unit use ISO18000-6C I series read write lines.
ISO18000-6C I series read write lines are long-distance electronic tag read write lines of new generation, and the label that read write line is supported mainly is abided by
From the passive electronic label of ISO18000-6C agreements.Read write line can be used to read and write, lock to 6C electronic tags for user
Feature operation.The read write line has principal and subordinate, the working method of three kinds of reading electronic tags of timing and triggering, and the communication for connecting controller connects
Mouth has RS-232, RS-485 and Wiegand interface, directly can connect with the control device with standard Wiegand W26 or W34 interface
Connect, can also be connected by standardized serial communication Interface and Controler, enter row data communication with exchanging.Work as pressure sensor unit
When food weight changes in detection refrigerator, the food labelling in triggering read write line scanning refrigerator, the read write line provides once
Read and write multiple labels.
Core Slab element carries out data interaction by wired network adapter unit and Internet network.Default refrigerator can be direct
The Internet of Things supermarket website of access, so as to be docked.User logs in shopping website by LCD touch screen and realizes lower single operation,
Give tacit consent to every refrigerator and be equipped with a special account to bind login, the page is submitted by POST modes.When refrigerator log in into
After work(, you can realize on-line purchase commodity and place an order.Food information and temperature ginseng in LCD touch screen real-time display refrigerator simultaneously
Number.
Core Slab element carries out data interaction by wireless communication unit and mobile terminal, and wireless communication unit uses
DU600GPRS/GSM modules.DU600 supports a variety of connection modes, it is possible to achieve the basic function with communication of mobile terminal.Intelligence
The GPRS/GSM modules of refrigerator only need short message receiving-transmitting and interpret the short message received, and awakening mode is selected by DU600
Instructed etc. short message to be received and after interpreting short message, and the control instruction is sent to PXA270 core boards and realizes purchase work(
Energy and query function.If in the given time user not yet reply confirmation purchase, cancel automatically this food purchase and
Disconnection is connected with GPRS；If client, which replys, in the given time confirms purchase, PXA270 core boards return to one and confirm purchase
Information and disconnect GPRS connections.
Food weight in pressure sensor unit collection refrigerator, pressure sensor unit use HX711 pressure sensors.
HX711 is a 24 A/D converter chips for aiming at high-precision electronic scale and designing.Eaten when in pressure sensor sensing refrigerator
PXA270 core boards can be just transmitted a signal to when product weight changes, while opens RFID card reader progress food labelling and sweeps
Retouch.When refrigerator is opened, PXA core boards are powered to pressure sensor, can record during the first task of pressure sensor just
Food weight in refrigerator when the beginning.When refrigerator is closed, the food weight of measurement pressure sensor sensing, and contrast initial
When refrigerator in food weight whether change, closing presure sensor and disconnect RFID card reader if not changing.
As shown in Fig. 2 temperature sensor unit includes temperature sensor U1 and resistance R1, temperature sensor U1 uses single line
Formula digital temperature sensor DS18B20, its is simple in construction not to need external circuitses, only with an I/O data line transfer data.Often
DS18B20 is realized multiple DS18B20 to be articulated in a data lines and is detected multi-point temp respectively by independent sequence number.
Code after DS18B20 conversions is not actual temperature value, it is necessary to carry out calculating conversion.Use first five position in temperature high byte
Come the positive and negative of storage temperature, latter three and eight be used for storage temperature value, wherein low byte low four of low byte of high byte
The decimal place of storage temperature.
As shown in figure 3,51 single machine units include 51 singlechip chip U2, quartz crystal oscillator X1, electric capacity C1~C3 and resistance
R2,51 singlechip chip U2 are 40pin 89C51 single-chip microcomputers, and electric capacity C1 is electrochemical capacitor.51 singlechip chip U2 pass through RxD pin
Data interaction is carried out with TxD pin and PXA270 core boards.
As shown in figure 4, refrigeration for refrigerator blade unit includes cooling piece U3, relay K1, triode Q1, diode D1 and resistance
R3, cooling piece U3 are semiconductor chilling plate, minimum reachable -10 DEG C.
Due to PXA270 core board circumscription socket problems, temperature sensor DS18B20 is operated based on 51 single-chip microcomputer U2, thus
Without on embedded PXA270 core boards.Temperature sensor DS18B20 starts with the startup of refrigerator, will be warm in the refrigerator of collection
Degree is sent to 51 single-chip microcomputer U2,51 single-chip microcomputer U2 by the temperature of collection compared with the temperature value set, if higher than setting
Temperature value then opens cooling piece.If less than or equal to the temperature value of setting, cooling piece is closed down.
The invention provides a kind of Internet of Things intelligent refrigerator, using radio frequency identification (RFID) technology, with reference to internet and letter
Treatment technology is ceased, establishes intelligent refrigerator foods supervision system, realizes and the food of refrigerator is recorded, food can pass through refrigerator in refrigerator
Liquid crystal display real-time display, the food in refrigerator in refrigerator inquiry man can be also sent the SMS to by mobile terminal, so as to pass through
Mobile terminal buys food, is provided a great convenience to daily life, guarantor is provided for the healthy living of Modern Family
Barrier, reduce social resources waste, meet the green theory of contemporary society, meet the needs of following smart home.
