Embodiment
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
Embodiment 1
See Fig. 1 and Fig. 2, a kind of Intelligent vending machine based on technology of Internet of things of the present utility model comprises master control system 100, counter 200, rfid interrogator 300, POS 400 and peripheral containment structure 500, wherein master control system 100, rfid interrogator 300 and POS 400 can be integrated in counter 200, can certainly arrange separately.
Master control system 100, as the maincenter of automatic vending machine, is responsible for coordination and the management of automatic vending machine whole system.Master control system 100 comprises single-chip microcomputer 110, power supply 120, photo-coupler 130 and relay 140.Single-chip microcomputer 110 comprises for the treatment of the central processing unit of data-signal, for storing the storage unit of data, power interface and for the signal input interface of receiving data information number and the signal output interface for outputting data signals.The power interface of single-chip microcomputer 110 is connected with power supply 120, and is powered by this power supply 120.In the present embodiment, single-chip microcomputer 110 can also adopt micro computer to replace.
Master control system 100 also comprises a host computer 150, and host computer 150 is connected with single-chip microcomputer 110, and it can perform the partial function of single-chip microcomputer 110, as the data processing etc. of complexity.In the present embodiment, host computer 150 is computer.
A cavity is formed in counter 200, commodity miscellaneous are deposited in the cavity of counter 200, each commodity is all pasted with RFID label tag, merchandise news is stored in RFID label tag, merchandise news comprises trade name, commodity price, the place of production, weight, date of manufacture, shelf-life, production firm etc., and some relate to the information of commodity self character, certainly can also comprise some information relevant with safety and Health such as the sugar content of commodity, suitable population, application notice.
Counter 200 is provided with a counter door 210, counter door 210 is connected with master control system 100, and control it by master control system 100 to open or close, particularly, the signal output interface of the single-chip microcomputer 110 of master control system 100 successively by photo-coupler 130 and relay 140 be arranged on to open or the topworks 211 of shutoff operation is connected for performing counter door 210 on counter door 210.
Be provided with a RFID antenna 220 in counter 200, RFID antenna 220 is arranged on the inwall of the cavity of counter 200.
Counter door 210 is provided with a signal shielding network (not shown), so can ensures after commodity are removed counter 200, the RFID antenna 220 in counter 200 no longer can read the RFID label tag on the commodity that are removed.
In addition, counter door 210 is provided with one for opening the handle of counter door 210 or closedown counter door 210, this handle is provided with an induction installation, such as induction installation is capacitance type sensor, when the hand of client covers handle, touch the capacitance type sensor be arranged on handle, now capacitance type sensor senses capacitance variations, meanwhile pass to master control system 100 1 signals, customer need is opened counter door 210 and is chosen commodity in counter 200 to allow master control system 100 learn.Certainly, induction installation can also be pressure transducer, infrared ray sensor etc., and concrete methods of realizing belongs to routine techniques, particularly car door has more application in a lot of fields, does not just repeat one by one at this.
Similarly, master control system 100 also can know that client chooses required commodity and these commodity are taken out counter 200, itself and above-mentioned master control system 100 are known and customer need are opened counter door 210 to choose the mode of the commodity in counter 200 roughly the same, namely when client chooses required commodity and after these commodity are taken out counter 200, client closes counter door 210 by the handle be arranged on counter door 210, now touch the induction installation be arranged on handle, this induction installation senses change, namely master control system 100 1 signals are given, client chooses required commodity and these commodity is taken out the information of counter 200 to allow it know.
The counter door 210 of counter 200 is also provided with one to be connected with master control system 100 and to control its second electronic lock 230 switched between locking state or released state by master control system 100.When master control system 100 knows that customer need opens the counter door 210 of counter 200, master control system 100 controls the second electronic lock and cuts 230 and change to released state, is convenient to counter door 210 and is opened; When master control system 100 knows that client chooses commodity and takes out counter 200, master control system 100 controls the second electronic lock and cuts 230 and change to locking state, in order to lock counter door 210.
