The utility model has been owing to adopted radio frequency identification module, and is connected with remote server by the network transmission, can understand and manage the interior food storing information of current refrigerator in real time;

The utility model is transferred the information in the remote server owing to can connect remote server, and a large amount of menus can be provided, collocation of scientific arrangement diet and cooking methods.

Description of drawings

Fig. 1 is the general structure schematic diagram of the utility model food supervision refrigerator system;

Fig. 2 is the structural representation of the radio frequency identification module of the utility model food supervision refrigerator system;

The specific embodiment

Below in conjunction with the description of drawings specific embodiment of the present utility model.

See also shown in Figure 1, the utility model food supervision refrigerator system comprises one-chip computer module 1 and the radio frequency identification module 2 that is connected with one-chip computer module 1 respectively, network transmission module 3, display module 4 and input module 5, and described network transmission module 3 is connected with far-end server 6.

The hardware device that one-chip computer module 1 adopts is single-chip microcomputer XSBASE270, the PXA270 embedded microprocessor that this single-chip microcomputer adopts Inter company to produce, high primary frequency can reach 520MHz, the software systems that single-chip microcomputer XSBASE270 adopts are WinCE, because framework is similar substantially with the windows system, so, just be easy to the software transplanting of some desktop systems to the WinCE system as long as recompilate some codes.

The structure of radio frequency identification module 2 sees also Fig. 2, it comprises the card reader module 21 that is connected with one-chip computer module 1, the antenna 22 that is connected with card reader module 21, and by the electronic tag circuit 23 of antenna 22 with card reader module 21 radio communications, adopt the card reader module 21 of radio frequency development board ZLG500B as RF identification in the utility model, this radio frequency development board mainly comprises radio receiving transmitting module, antenna, control module and interface circuit.Card reader module 21 is the ancillary equipment of the utility model food supervision refrigerator system, need be undertaken by serial port with the communication of one-chip computer module 1 in the system, the user can select to use various serial interface circuits as required, card reader module 21 is under current relevant radio frequency confinement, the most of regional isotropism Effective Radiated Power in Europe is limited in 500mw, such radiant power is at 870MHz, can be similar to reach 0.7 meter.The U.S., Canada and some other country, it is 4W that the radiation that need not to authorize is constrained to isotropically radiated power, such power will reach 2 meters reading distance, and under the situation of obtaining the authorization, the power of launching 3OW in the U.S. will make read area increase to about 5.5 meters.The radio frequency development board ZLG500B provide built-in function under the Windows environment, can call built-in function during exploitation and realize correlation function.But under the WinCE development environment, but can't call this built-in function, thus must write again one with the similar class of built-in function function.

By research card reader internal communication protocol using and instruction format and relevant preset instructions, write one with the similar class of built-in function function, realized by debugging successfully repeatedly, name such ZLG500B by name.The correlation function that just can call flexibly in such when designing and realizing based on the intelligent refrigerator system of WinCE is realized needed correlation function.

At first baud rate and string slogan are set, and open being connected between development board and the card reader by the function ZLG500B () after the encapsulation again.

1. open manual Card Reader pattern or timer pattern

After opening card reading module by ZLG500_Open () function.Can use manual or timer Card Reader pattern, the former needs the manual operation terminal to read information in radio frequency at every turn, whether the real-time cycle criterion of the latter reads information in radio frequency and return of value, opens the work of then reading information in radio frequency after the corresponding pattern.

2. read the action of information in radio frequency

If be stuck in the induction zone, then can judge whether the RF identification numbering of original card, if read then advance to read relevant action behind the information in radio frequency by function zlg500_SNR ().

3. follow the relevant action that reads information in radio frequency

In native system, after Card Reader is read related data, then can send the information of the corresponding numbering of instruction inquiry by ICP/IP protocol, and all information of returning under this RF identification numbering show in system by the RF identification numbering.

4. reading information in radio frequency finishes

When all when reading end-of-job, can call function ZLG500_Close () close serial ports or quit a program.

Electronic tag circuit 23 is made up of coupling element and chip, wherein comprise band encryption logic, serial EEPROM (electric erasable and formula read-only storage able to programme), microprocessor and radio-frequency receiving-transmitting and interlock circuit, and each responder has globally unique identifier (UID), has guaranteed security.

Network transmission module 3 can adopt transmission control protocol/internet interconnection protocol or UDP, and what adopt in the utility model is transmission control protocol/internet interconnection protocol.The flow process of writing of this transmission control protocol is that at first the TCP server end calls the socket function and sets up stream socket, call bind function binding local address then, then call the Listen function and monitor the client connection, in case after listening to the client connection request, server socket will be called the Accept function and accept the client connection request, and connect, the while server end can newly add an independent socket and client communicates.

The utility model adopts LCD as display module 4, and touch-screen has been installed as input module 5 on display.

Although content of the present utility model has been done detailed introduction by above preferred embodiment, will be appreciated that above-mentioned description should not be considered to restriction of the present utility model.After those skilled in the art have read foregoing, for multiple modification of the present utility model with to substitute all will be conspicuous.Therefore, protection domain of the present utility model should be limited to the appended claims.
