Description
Technical field
The utility model relates to a kind of automatic vending machine, especially relates to a kind of intelligent sound broadcast device that is used for automatic vending machine.
Background technology
Existing automatic vending machine is a kind of brand-new retailing form, and grow up from Japan and America and Europe the seventies in 20th century.It is otherwise known as miniature supermarket of 24 HOUR ACCESS.In Japan, 70% tinned drink is sold by automatic vending machine.The whole world famous beverage merchant Coca-Cola just is furnished with 500,000 Drink dispensers in the whole world.In all parts of the country in Japan, automatic vending machine is very general.At the enterprising line operate of the display screen of vending machine, input commodity number and quantity purchase, and after dropping into coin, commodity will come out from access section, even from cater, can also buy heat z z z noodles and rice group.And at home, along with development of science and technology, automatic vending machine is also more and more general, and because it is convenient and swift, saves manpower, later on will be more universal.
At present, the coin device of automatic vending machine and storage goods selling equipment are all quite perfect, and we can buy the commodity of wanting easily, generally mistake can not occur.Blemish in an otherwise perfect thing is, voice broadcast function is seldom arranged, but flicker (meaning that the representative that flickers is enclosed on the next door) by pilot lamp passed on certain information to client.And in actual life, language is mainly leaned in our interpersonal interchange, when doing shopping at ordinary times, we are often more responsive to shop-assistant's language, such as she remind your these commodity how much, perhaps tell you not have change to look for you now, tell perhaps you this money is counterfeit money, or the like.The effect of these language is that label or the prompting on the shelf on the commodity is incomparable.Just said nothing of the pilot lamp on the automatic vending machine, people can ignore it easilier.So from the angle of hommization, it is that market outlook are arranged very much that vending machine has voice broadcast function.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of simple in structure, the intelligent sound broadcast device that is used for automatic vending machine easy to use.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of intelligent sound broadcast device that is used for automatic vending machine, comprise the central control circuit that is arranged on automatic vending machine, described central control circuit is provided with key device and liquid crystal indicator, described central control circuit is that C8051F020 microcomputer development plate constitutes by model mainly, be connected with the speech chip that model is ISD1790 on the described central control circuit, be connected with loudspeaker and microphone on the described speech chip.
Described key device comprises that model is the integrated circuit (IC) chip of ZLG7289, and described integrated circuit (IC) chip is externally connected with 16 buttons.
Compared with prior art, advantage of the present utility model is the voice broadcasting system that comes into the picture easily by adding, the sense of hearing sensorium who utilizes people to be accustomed to realizes the operating process of automatic vending machine, and by liquid crystal indicator commodity and price thereof, this will bring great convenience to people.Utilize speech chip and single-chip microcomputer to record and play corresponding phonetic order.Speech chip can be recorded, can wipe, but also storaged voice instruction, record length reaches 90 seconds most, and is easy and simple to handle, and peripheral circuit is simple; Nearly 16 of external buttons can the multiple phonetic order of typing, so that tackle various emergency situations; The at present domestic Related product listing that does not have as yet at the voice suggestion that is applied to the vending purchasing commodity so this module has the innovation part in application facet, has market outlook preferably.

Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As shown in the figure, a kind of intelligent sound broadcast device that is used for automatic vending machine, comprise the central control circuit 1 that is arranged on automatic vending machine, central control circuit 1 is provided with key device 2 and liquid crystal indicator 3, central control circuit 1 is that C8051F020 microcomputer development plate constitutes by model mainly, being connected with model on the central control circuit 1 is the speech chip 4 of ISD1790, is connected with loudspeaker 5 and microphone 6 on the speech chip 4.Key device 2 comprises that model is the integrated circuit (IC) chip 21 of ZLG7289, and integrated circuit (IC) chip 21 is externally connected with 16 buttons 22.
Core of the present utility model is an ISD1790 speech chip 4, its principle of work as shown in Figure 2: 4,5,6,7 pins have been formed synchronous serial Peripheral Interface SPI, are used for communicating with single-chip microcomputer.Wherein, the external main frame input/slave of 4 pin output data line MISO is to the single-chip microcomputer internal input signal; The external main frame output/slave of 5 pin input data line MOSI accepts the control signal that single-chip microcomputer is exported, and calls the phonetic order in the appropriate address; The external serial time clock line SCLK of 6 pin, 7 pin are sheet choosing end/SS, and low level is effective, and internal pull-up resistor is arranged.10,11 pin connect the both positive and negative polarity of microphone, can record.13,15 pin connect loudspeaker, can play sound.Chip power supply voltage is 5V.Central control circuit 1 is a core with C8051F020 microcomputer development plate, and the typing and the broadcast of voice signal had control function.The C8051F020/1/2/3 device is fully-integrated mixed-signal system level MCU chip, has 64 digital I/O pins (C8051F020/2) or 32 digital I/O pins (C8051F021/3).We utilize its abundant peripheral port and control button, by typing and the broadcast by each bar instruction of key control, realize the commodity purchasing process to reach under the prompting of voice, promptly finish the phonetic function of voice vending machine.Also utilize its inner timer in addition, the duty of control vending machine.Its principle of work as shown in Figure 3, the SPI tandem system of the P3.0 of C8051F020 single-chip microcomputer, P3.1, P3.2, P3.3 mouth and speech chip communicates.By calling several special functions in the program, as play function ISD_SET_PLAY (the uchar Saddl that regularly fixes a point, Saddh, Eaddl, Eaddh), recording function ISD_SET_Rec (uchar Saddl regularly fixes a point, Saddh, Eaddl, Eaddh), regularly fixed point is wiped function ISD_SET_Erase (ucharSaddl, Saddh, Eaddl, Eaddh) etc., Saddl wherein, Saddh, Eaddl, Eaddh is respectively low eight of start address, the high eight-bit of start address, end address low eight, the high eight-bit of end address, in our address field that the prior typing of a rule phonetic order is fixing, and then by these addresses broadcast corresponding instruction of inquiry.We can be by revising the suitable distribution address space of gap length of high low address, so that adapt to the phonetic order of different length.
The C8051F020 single-chip microcomputer relies on and reads the external key value with communicating by letter of ZLG7289 integrated circuit (IC) chip 21, selects to carry out corresponding instruction whereby.As shown in Figure 4, external 16 buttons 22 of ZLG7289 chip, its abundant button can be used to select multiple phonetic order.The 6 pin sheets choosing end/ss of chip links to each other with the P3.4 mouth of F020 single-chip microcomputer, and chip selection signal is provided; 7 pin clock signal terminals of chip connect the P3.5 mouth; 8 pin data-signal ends of chip connect the P3.6 mouth, are used for the transmitted in both directions of data, and popular saying sends key value to single-chip microcomputer exactly; 9 pin of chip then connect the P3.7 mouth, are used to receive the keyboard interrupt request signal, and low level (marginal edge) is effective.Liquid crystal indicator 3 is selected MzL05-12864 LCD LCDs for use, and pixel reaches 128*64, can show all kinds of any characters.
By control flow chart shown in Figure 5, just can realize roughly that by designing corresponding program code the purchasing process of commodity is as follows: voice suggestion: the commodity that please select you to want
