Compared with prior art, the client that the some vegetable-growing area confession that several dish-order devices can be placed on hotel lobby by the utility model comes to have dinner orders dishes; The specialties that system can recommend component appropriate according to number of having dinner, avoid causing unnecessary food waste; Utilize existing line of electric force, by the menu information that the different dining table of carrier system high-speed transfer is corresponding, effectively shared the part work of waiter, there is the feature of robotization, hommization.
Accompanying drawing explanation
Fig. 1 is the arrangement plan of the embodiment of the utility model device.
Fig. 2 is the structural drawing of the embodiment of the utility model device.
Fig. 3 is the implementation method process flow diagram of a kind of embodiment of the utility model device.
Embodiment
Embodiment of the present utility model is described in detail below in conjunction with drawings and Examples.
As depicted in figs. 1 and 2, a kind of dish-order device based on PLC technology of the utility model, comprises dish-order device 1, line of electric force 2, electric power networks bridge a4, electric power networks bridge b5, control center 3.
Wherein, dish ordering terminal 1 can have several, orders dishes in real time for making client.Be arranged at dining area, such as dining table position or dining room hall, comprise dining table and select module and dish selection module, described dishes ordering information comprises selected vegetable and selected dining table, when dish ordering terminal 1 is fixedly installed on dining table, dining table is selected the module current dining table of silent selection and can not be edited.Electric power networks bridge a4 also has several, corresponding with dish ordering terminal 1, is arranged at line of electric force 2 one end, dishes ordering information is modulated on line of electric force 2; Line of electric force 2, for transmitting described dishes ordering information; Electric power networks bridge b5, is arranged at line of electric force 2 other end, the dishes ordering information that line of electric force 2 described in demodulation transmits; Control center 3 is with display screen, be arranged at kitchen area, the dishes ordering information receiving its demodulation and obtain is connected with electric power networks bridge b5, and show on a display screen, control center 3 comprises multizone display module, multiple dishes ordering information is shown on a display screen by the number of times receiving dishes ordering information, and according to receiving the order sequence of dishes ordering information.
Based on said apparatus, the method for ordering dishes as shown in Figure 3.
Step one: when client orders dishes on dish-order device, input dining table number and men and women's number of having dinner, select recommend vegetable or certainly order vegetable, click is determined, recommends vegetable, then carry out step 2 if select; From orderring vegetable, then step 5 is carried out if select;
Step 2: system can recommend corresponding set meal according to the size combinations of men and women's number of client's input and different vegetable component;
Step 3: client browses the vegetable of recommendation, selects the need of certain vegetable of replacing, if need not change, then clicks and determines; Otherwise carry out step 4:
Step 4: client can select certain vegetable recommended in vegetable to be replaced by other vegetables voluntarily, and click is determined;
Step 5: client browses whole vegetable, and order dishes according to the hobby of oneself, according to men and women's number that client inputs, system judges that whether put vegetable is too much, when vegetable is too much, system provides corresponding prompting, and after client determines menu, click is determined;
Step 6: the menu information that client puts is modulated on line of electric force 2 by electric power networks bridge a4, transmits menu information by PLC technology:
Step 7: electric power Net Bridge b5 by the menu information demodulation on line of electric force 2, and is transferred to control center 3, for cook's reference that kitchen staff behind hotel does.
Wherein, described electric power networks bridge a4 comprises analog to digital conversion circuit, spread spectrum chip, power amplification circuit and coupled circuit, and by the menu information that dish-order device 1 obtains, the concrete steps be modulated on line of electric force 2 are for it:
Step one: the menu information obtained by dish-order device 1 is transferred to spread spectrum chip with digital quantity form and modulates, and makes it become modulation signal:
Step 2: modulation signal carries out frequency-selecting and amplification through power amplification circuit;
Step 3: the modulation signal after amplification injects line of electric force 2 efficiently through overcoupled circuits.
Wherein, the mode that described modulation system adopts Binary Frequency Shift Keying to combine with direct sequence spread spectrum, its implementation is simple, be mainly used in middle slow data transmission, and the temperature signal after being modulated by Binary Frequency Shift Keying carries out direct sequence spread spectrum and can strengthen its anti-interference, also there is good performance in the bit error rate etc. in other.
Correspondingly, electric power networks bridge b5 comprises coupled circuit, filtering circuit and spread spectrum chip, and the concrete steps of the menu information demodulation that line of electric force 2 transmits are by it
Step one: need the menu information received to be transmitted by line of electric force 2, after overcoupled circuits denoising, filtering, realize minimal attenuation and the optimum reception of useful signal;
Step 2: the menu information after coupling carries out filtering by filtering circuit to it;
Step 3: the menu information after filtering is transferred to spread spectrum chip and carries out demodulation.
Can be recognized by the concrete scheme of above-described embodiment, this system can utilize existing line of electric force to transmit menu information by ZAP, and according to the specialties that the actual conditions of the personnel of having dinner recommend component appropriate, or remind vegetable that client orders too much, to avoid causing unnecessary food waste, thus reach the object that active response " CD action " calls, there is hommization, intelligentized feature.
Finally it should be noted that: above-described embodiment is only in order to illustrate the technical solution of the utility model, non-to its restriction.Although be described in detail the utility model with reference to above-described embodiment; the technician of the industry should recognize: it can be modified to the technical scheme of above-described embodiment; or wherein portion of techniques feature is replaced; but these amendments or replacement, do not make the essence of its technical method depart from thought of the present utility model and protection domain.
