Abstract
The invention discloses a false coin recognition device of a coin inserting machine, and belongs to the technical field of electronics. The false coin recognition device comprises a power supply, a microcontroller, a sound sensor and an alarm, wherein the sound sensor and the alarm are connected with the microcontroller, and the microcontroller is connected with the power supply. On the basis of an original coin inserting machine, the microcontroller, the sound sensor and the alarm are additionally arranged, whether inserted coins are false coins or not is recognized through the judgment of sound of the coins, the alarm will make a sound to warn a driver if the inserted coins are the false coins, working efficiency is high, and loss of bus companies is reduced. The false coin recognition device is simple in structure, easy to manufacture and low in cost.
Description
Technical field
The invention discloses a kind of counterfeit money recognition device of slot machine, belong to electronic technology field.
Background technology
Lifting along with supvr's theory; increasing bus adopts the self-service ticketing machine to replace the ticket seller; but present self-service ticketing machine; only limit to coin function; do not have the counterfeit money recognition function; only the sound of listening to coin and voting machine collision by two power with the driver judges whether to be counterfeit money; this kind judged the method for counterfeit money; efficient is lower, and not necessarily all can both recognize the sound of counterfeit money, therefore; most of bus is received counterfeit money through regular meeting; as the game machine coin etc., the quantity that has is a lot of, brings certain loss for bus company.
Summary of the invention
In order to solve the problem that exists in the above-mentioned technology, the invention discloses a kind of counterfeit money recognition device of slot machine, can identify counterfeit money, the recognition efficiency height reduces the loss of bus company.
In order to achieve the above object, the invention provides following technical scheme: the counterfeit money recognition device of this slot machine, comprise power supply, microcontroller, and the sound transducer that links to each other with microcontroller and alarm, microcontroller is connected with power supply.
Further, alarm is music player or hummer.
Further, microcontroller is single-chip microcomputer 80C51.
Compared with prior art, the present invention is on the basis of original slot machine, increase microcontroller, sound transducer and alarm, by judge currency sound identify the currency of throwing whether be counterfeit money, if as counterfeit money, then alarm can be sounded, and reminds the driver, high efficiency, and reduced the loss of bus company.The present invention is simple in structure, be easy to make, and cost is low.
Description of drawings
Fig. 1 is the present invention's electricity theory diagram.
Embodiment
The invention will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of counterfeit money recognition device of slot machine is made up of power supply, microcontroller, sound transducer and alarm, and microcontroller links to each other with power supply, sound transducer and alarm respectively by lead.
As improvement of the present invention, described alarm is music player or hummer, can send alarm sound.
As a further improvement on the present invention, described microcontroller is single-chip microcomputer 80C51.
During work, connect power supply, sound transducer is gathered the bump sound of coin and slot machine, and the data of gathering are sent to microcontroller, microcontroller is handled and is analyzed the sound that receives, in case data are undesired, then microcontroller starts alarm, send alarm sound, remind coin that the driver throws to be counterfeit money, thereby the driver can in time be known, and check whether this coin is counterfeit money, to reduce the loss of car company of the state, improved the judging efficiency of counterfeit money simultaneously.
Claims (3)
