Embodiment
Below in conjunction with accompanying drawing, preferred embodiment is elaborated.Should be emphasized that following explanation only is exemplary, rather than scope and application thereof in order to limit the utility model.
This automatic formula order dishes system mainly is made up of computing machine, 1 radio receiving terminal (receiver) and a plurality of wireless transmit terminal node, has constituted a data acquisition system (DAS) based on the ZigBee wireless protocols.As shown in Figure 1.
Each wireless transmit terminal is accomplished ordering dishes of guest on each dining table and is sent to radio receiving terminal (receiver) through the ZigBee wireless network, and through the telecommunication cable real-time Transmission to the computing machine that is placed in the kitchen.
On the menu in the restaurant, every kind of dish all is furnished with picture and unique numerical coding.Each dining table is finished number in advance, all is assigned the wireless transmit terminal of a band LED display, and is as shown in Figure 2.
The display screen of wireless transmit terminal node is digitron display screen or LCDs.Demonstration can supply the numbering of various dish, all can through by on the lower keyboard increase button " Δ ",
manually adds and subtracts dish numbering and realizes the selection to dish to subtract button.The below of increase and decrease button is ACK button
and cancel button " Esc ".When numbers displayed on the light emitting diode is the dish numbering that need select; Press affirmation
button; When the corresponding dish of the numbering that shows on the light emitting diode need be cancelled; Can press cancel button " Esc "; When client accomplishes when ordering dishes, can press the completion button " Ovr " of below of wireless transmit terminal.
Native system mainly is made up of three parts, is respectively the logical computing machine of a plurality of wireless transmit terminal, radio receiving terminal and a Daepori and forms.Embodiment is following:
Fig. 3 arranges synoptic diagram for the dining room, and wireless transmit terminal of each separate room or table configurations is as ordering dishes equipment.Radio receiving terminal is connected through USB interface with computing machine, and the data that radio receiving terminal receives are uploaded to computing machine by USB interface, computing machine adopt written program in advance to data store, the processing of calculating and visualization display.The wireless transmit terminal in whole dining room and radio receiving terminal constitute a ZigBee network, and radio receiving terminal is responsible for setting up network as the telegon of network, and communication just can be carried out with telegon after adding network in the wireless transmit terminal.
Fig. 4 is the connection layout of dining room radio receiving terminal and computing machine, and computing machine is connected through USB interface with the USB/UART modular converter of radio receiving terminal.The USB/UART modular converter converts USB interface into the UART interface so that second wireless singlechip and Computer Processing.Second wireless singlechip (CC2530) can be supported up-to-date ZigBeePRO protocol stack, through the application layer of ZigBeePRO protocol stack is developed, just can realize function corresponding.Second wireless singlechip (CC2530) will be set at the ZigBee telegon through the mode of programming.The software section of computer terminal adopts VC++ to develop, and it mainly is made up of human-computer interaction interface, serial port service thread, database service thread and database.When the ZigBee telegon receives effective data frame; It can be uploaded to computing machine by serial port with this Frame; The serial port of computing machine service thread sends to human-computer interaction interface and database service thread respectively after with data processing: human-computer interaction interface shows data, notifies the dining room related personnel to carry out dish thus and processes; The database service thread is responsible for storing data, and when shopper checkout, the data that the cashier can access in the database are calculated the generation bill automatically by computing machine.
Fig. 5 is wireless transmit terminal structure figure, and the wireless transmit terminal is fixed on the dining table, and its core is first wireless singlechip (CC2530), and peripheral components comprises 4 * 4 keyboards, small display screen and accumulator etc.First wireless singlechip (CC2530) is supported the ZigBeePRO agreement, is set to the ZigBee router through protocol stack being configured it, can directly or through routing mode communicate by letter with the telegon end.Display screen is connected through the UART interface with CC2530.Display menu item, each dish numbering and title, the affirmation of ordering dishes on request of the driver that includes display screen among the CC2530, display screen, order dishes and cancel etc.Button part is made up of 16 buttons, comprising numerical key 1-9, acknowledgement key (OK), cancel key (CANCEL), directionkeys (upper and lower, left and right).Numerical key is used to select the dish of corresponding numbering, and acknowledgement key is used for confirming the dish of orderring that cancel key and be used to cancel current input, directionkeys is used for navigate through menus or browses and order dish.In addition; One-one relationship in order to ensure wireless transmit terminal and dining table; The wireless transmit terminal need number be registered to the database of computing machine before use in the lump together with dining table; The wireless transmit terminal adopts the IEEE address of its ZigBee network as identity information, and each ZigBee equipment all has globally unique IEEE address, adopts this mode can guarantee the one-to-one relationship of wireless transmit terminal and dining table.The IEEE address at wireless transmit terminal can be read from display screen through program.Storage battery power supply is adopted at the wireless transmit terminal, when wireless transmit terminal power supply is not enough, can charge.
This product has been realized electric order dishes through wireless mode; Thoroughly realized ordering dishes with no paper at all; And can realize complete self-service ordering dishes, client's dishes ordering information very sent to the kitchen in time, thereby can significantly reduce the attendant; Accelerate the speed of serving, significantly improve Service Quality in Hotels and service level.
The above; Be merely the preferable embodiment of the utility model; But the protection domain of the utility model is not limited thereto; Any technician who is familiar with the present technique field is in the technical scope that the utility model discloses, and the variation that can expect easily or replacement all should be encompassed within the protection domain of the utility model.Therefore, the protection domain of the utility model should be as the criterion with the protection domain of claim.
