Embodiment：

In Fig. 1 examples, intelligent meal ordering system includes：

Single machine unit 1, interface unit 2, storage unit 3, voice recognition unit 4, push-button unit 5, display unit 6, number According to transmission unit 7.

Wherein, the single machine unit is led to 1 excessively described interface unit 2 and is coupled with 3 phase of storage unit；The microcontroller Unit 1 is coupled with 4 phase of voice recognition unit；The single machine unit is coupled with 15 phase of push-button unit；The monolithic Machine unit 1 is coupled with 6 phase of display unit；And the single machine unit 1 is coupled with 7 phase of data transmission unit.

As shown in Figure 1, single machine unit 1 couples storage unit 3 by interface unit 2, the letter that every table guest is inputted All storage is into storage unit 3 for breath, with noting down.Wherein, single machine unit 1 is microprocessor（MPU）, select sexual valence to compare High STC12C5A60S2 types microprocessor.Storage unit 3 selects SD card memory, and the memory capacity of SD card memory is big, and It is small, it is light-weight, it is easy to carry, it is suitable for the utility model.

According to a kind of implementation, interface unit 2 is SPI（Serial Peripheral Interface, serial peripheral Interface）Bus, SD card（Secure Digital Card）Memory (example as storage unit 3) can pass through spi bus Coupled with 1 phase of single machine unit.

In addition, single machine unit 1 is also coupled to voice recognition unit 4, voice recognition unit 4 can make the utility model have The function of voice control.User can be added or delete vegetable by voice, confirm to send and check a systems such as bill The operation of row.Wherein, voice recognition unit 4 is LD3320 voice recognition chips, integrated chip voice recognition processor and Some external circuits, including AD, D/A converter, microphone interface, sound output interface etc..This chip volume is small, stability is strong, It is cost-effective, it is not necessary to which that external any companion chip such as Flash, RAM etc., being directly integrated in existing product both can be real Existing speech recognition/acoustic control/good in interactive function, can perfectly meet the needs of the utility model.

Single machine unit 1 is also coupled to push-button unit 5.In this way, single machine unit 1 can be used by push-button unit 5 The control command at family, so that user can be controlled whole intelligent meal ordering system.Wherein, push-button unit 5 is the square of 4*4 Battle array keyboard.4*4 matrix keyboards one share 16 buttons, by this 16 buttons can to 1 input control order of single machine unit, So as to control the work of the utility model.

Display unit 6 selects common LCD12864 LCD screens on the market.12864 Liquid Crystal Modules are 128*64 dot matrix liquid The dot matrix number of crystal module is referred to as.LCD12864 uses+5V powers.This intelligence meal ordering system is shown using LCD12864 LCD screens Show information, such as the current state of intelligent meal ordering system, the current menu name chosen and relevant prompt message etc..

It will be noted from fig. 1 that single machine unit 1 is also coupled to data transmission unit 7.Wherein data transmission unit 7 uses SIM800A modules.SIM800A modules support working frequency range be：GSM900/1800MHz, is used for realization and sends information to rear kitchen Function.After dining personnel send single machine unit 1 " confirming to send " order, SIM800A is short to sending in certain cell-phone number Message, is sent to the demand of dining personnel in the form of short message among this mobile phone.

As can be seen from the above description, the user of above-mentioned embodiment according to the present utility model by key-press input either The dining demand of oneself is sent to microcontroller by phonetic entry, and microcontroller is sent to rear kitchen after being stored to the demand.Also It is to say, the utility model can at least help the staff in restaurant to complete the work of ordering in dining room, so as to greatly improve The work efficiency in restaurant.

Fig. 2 shows that one of a kind of intelligent meal ordering system shown in Fig. 1 applies exemplary circuit figure.

As shown in Fig. 2, in this applies example, STC12C5A60S2 microcontrollers 1（Example as single machine unit 1）, It passes through spi bus 2（Example as interface unit 2）Couple SD card 3（Example as storage unit 3）.Meanwhile STC12C5A60S2 microcontrollers 1 are also coupled to LD3320 voice recognition chips 4（Example as voice recognition unit 4）.In addition, STC12C5A60S2 microcontrollers 1 respectively with 4*4 matrix keyboards 5（Example as push-button unit 5）, LCD12864 Liquid Crystal Modules 6 （Example as display unit 6）, SIM800A wireless data transfer modules 7（Example as data transmission unit 7）It is connected.

Wherein, STC12C5A60S2 microcontrollers 1 couple SD card 3 by spi bus 2, and the utility model is completed to remember with this Recording function, developer can set specific record content according to specific operating environment, so as to the staff in dining room More preferably, the utility model is more easily used.

In addition, STC12C5A60S2 microcontrollers 1 are also coupled to LD3320 voice recognition chips 4, LD3320 voice recognition chips 4 The voice for being responsible for sending user is converted to order, so as to control whole system.The specific implementation of LD3320 voice recognition chips 4 Mode is sufficiently complex, is introduced one by one in this inconvenience, developer can voluntarily search handbook, to develop, although these are time-consuming Laborious, but these work are all the everyday tasks of developer.

As shown in Fig. 2, STC12C5A60S2 microcontrollers 1 couple 4*4 matrix keyboards 5,4*4 matrix keyboards totally 16 buttons, But only need to take 8 pins of STC12C5A60S2 microcontrollers 1, STC12C5A60S2 microcontrollers 1 are by scanning this 8 pins Level change, so as to judge specifically which button is pressed.

STC12C5A60S2 microcontrollers 1 are also coupled with 6 phase of LCD12864 Liquid Crystal Modules, wherein, LCD12864 Liquid Crystal Modules 6 Powered using+5V, a certain appropriate pin of STC12C5A60S2 microcontrollers 1 controls letter as the RS of LCD12864 Liquid Crystal Modules 6 Number, it is data manipulation as RS=1 for determining that microcontroller is to carry out data selection or instruction selection；It is to write finger as RS=0 Order or read states operation；The a certain appropriate pin of STC12C5A60S2 microcontrollers 1 determines microcontroller pair as R/W selection signals LCD12864 Liquid Crystal Modules 6 are to carry out read gate or write gate；The a certain appropriate pin of STC12C5A60S2 microcontrollers 1 connects The enable signal E of LCD12864 Liquid Crystal Modules 6, determination data are latched or are read；STC12C5A60S2 microcontrollers 1 Certain 8 interface meets DB0 ~ DB7 of LCD12864 Liquid Crystal Modules 6, for data transmission therebetween.In this way, LCD12864 liquid Crystal module 6 can be programmed to show that we desire to the information of user's presentation.

Finally, 7 phase of STC12C5A60S2 microcontrollers 1 and SIM800A wireless data transfer modules couples, and SIM800A is wireless Data transmission module 7 is powered using single supply, voltage range 3.4V ~ 4.4V.Powered using single supply, electric current will be capable of providing height Up to the peak point current of 2A to ensure to work normally in burst mode.Wherein, SIM_VDD interfaces are SIM card power interface, Need to connect 1.8V/3.0V power supplys.UART1_TXD pins connection in SIM800A wireless data transfer modules 7 RXD pins in STC12C5A60S2 microcontrollers 1, the UART1_RXD pins connection in SIM800A wireless data transfer modules 7 TXD pins in STC12C5A60S2 microcontrollers 1.SIM800A wireless data transfer modules 7 can be in STC12C5A60S2 monolithics Communication function is completed under the control of machine 1, realizes the function of alarming in the utility model patent.

The above, is only the most preferred embodiment of the utility model, and limit in any form is not done to the utility model Make, every any type of simple modification made according to the technical essence of the utility model to this, in the range of equivalent variations, all Belong within the scope of protection of the utility model.
