[technical field]

The utility model relates to the Coin-freed video game machine field, relates in particular to many standard radio frequencies card controller of Coin-freed video game machine.

[background technology]

There is following deficiency in the Coin-freed video game machine that generally adopts at present:

1. employing coin-freed mechanism, actuating mechanism are complicated, and material consumption is more, and mechanical switch serviceable life is short, updating maintenance is inconvenient.

2. artificial coin is counted the trouble poor efficiency, and inconvenience is checked in financial management, and is easy to cause administrative vulnerability.

3. a controller can only be discerned a kind of radio-frequency card.

For addressing the above problem, it is 201020526221.X that the applicant has proposed the patent No., and name is called the patented claim of a kind of many standard radio frequencies of Coin-freed video game machine card controller; And on 04 13rd, 2011 Granted publications, this control device can overcome the deficiency of above-mentioned prior art, provided a kind of and was the basis with microcontroller technology and non-contact intelligent IC-card recognition technology; Have the e-finance management, no coin recreation starts, and adaptability is good; Reliability is high; Practical, simple in structure, can discern many standard radio frequencies of Coin-freed video game machine card controller of multiple international standard radio-frequency card.

Though many standard radio frequencies of the game machine card controller through after the applicant's improvement can realize that game machine does not have the coin e-management; But do not connect and managerial ability owing to do not possess network; Can not satisfy the demand of user network management, be unfavorable for promoting the use of of equipment.

[utility model content]

The purpose of the utility model solves the problems of the prior art exactly; A kind of many standard radio frequencies of Coin-freed video game machine card controller that has 485 interfaces is proposed; Not only can discern multiple radio-frequency card, and possess network connection and managerial ability, be convenient to the demand that the user realizes network management.

For realizing above-mentioned purpose; The utility model provides a kind of many standard radio frequencies of Coin-freed video game machine card controller that has 485 interfaces; Comprise control circuit, can discern smart card read/write circuit, relay switch output circuit and the RS485 interface circuit of multiple radio-frequency card; Said control circuit links to each other with the smart card read/write circuit, and the output terminal of control circuit is connected in the input end of relay switch output circuit, and the output terminal of relay switch output circuit is connected to the game machine switch; Be connected with the RS485 interface circuit on the serial port of said control circuit, the said contactless smart card recognition integrated circuit of discerning multiple radio-frequency card adopts the RC632 chip.

As preferably, said RS485 interface circuit is made up of the RS485 integrated circuit, and circuit is simple, and cost is low.

As preferably, said RS485 integrated circuit adopts 75176 chips, and circuit is simple, and cost is low.

As preferably, said control circuit is made up of microcontroller, and circuit is simple, and cost is low.

As preferably, said microcontroller adopts the 89C51 chip, and circuit is simple, and cost is low.

The beneficial effect of the utility model: the recreation that the utility model can satisfy Coin-freed video game machine starts requirement, can discern multiple international standard radio-frequency card, maintainable good, the electronization charge of good reliability, practical, user, simplifies and receives coin and keep accounts, reduce material consumption, be beneficial to environmental protection; And, possess network and connect and managerial ability, be convenient to the user and realize network management; Be beneficial to promoting the use of of equipment; Adopt the RS485 interface circuit, transmission range is long, has the multistation ability.The utility model is applicable to the various recreation facilities of inserting coins and starting.

Characteristic of the utility model and advantage will combine accompanying drawing to be elaborated through embodiment.
