Abstract
The utility model provides a wireless double-interface card reading system. The system comprises a card reader. The card reader comprises an MCU, a contact type IC card processing module in signal connection with the MCU, a non-contact type IC card processing module, a wireless transmitting-receiving chip, an external interruption device for inserting a contact type card, and an external interruption device provided with or without a non-contact type card. The system further comprises a receiving head. The receiving head comprises a receiving MCU, a receiving wireless transmitting-receiving chip being in signal connection with the receiving MCU and used for communicating with the wireless transmitting-receiving chip of the card reader and a USB interface used for communicating with a host computer. The wireless double-interface card reading system has a wireless working mode and a wired working mode for selection. The card reader is convenient to move and the moving distance is relatively far. The system has greater interface stability than a wired means.
Description
Technical field
The utility model relates to the mobile communication technology field, is specifically related to a kind of wireless pair of interface card-reading system.
Background technology
Due to modern contact card and the non-a large amount of uses that connect card, the quantity of the professional card reader needed is also progressively increasing, but general card reader is all that ray mode is arranged, general is all to communicate by wired USB interface and host computer, thereby completes host computer to contact card and the non-operation that connects card.Existing wired card reader is used existent defect as follows in reality:
1, be all generally to access computer by USB interface, need the driving that corresponding product is installed normally to use;
2, mobile also very inconvenient under wired USB pattern;
3, there is ray mode loose contact easily to occur;
4, wired usb communication easily causes the situation of computer crash.
Be accompanied by development and the maturation of wireless technology, the higher wireless chip of various integrated levels occurs in succession, as the chips such as ZIGBEE, bluetooth and WIFI occur, make wireless application more and more come greatly, in order to overcome wired ground inconvenience that brings, all can use wireless replacement wired, for this reason, general card reader is no exception, uses the wired greatly convenience of wireless replacement.
The utility model content
In view of this, be necessary for the background technology part describedly, a kind of novel pair of interface card-reading system that adopts the wireless way for transmitting signal is provided.
The purpose of this utility model is achieved through the following technical solutions:
A kind of wireless pair of interface card-reading system, it comprises:
Card reader, it comprises MCU, the external interrupt device that the Contact Type Ic Card processing module be connected with described MCU signal, non-contact IC card processing module, radio transmitting and receiving chip, contact card are inserted, non-ly connects the external interrupt device that the contact card has or not;
Receiver, it comprises that the reception radio transmitting and receiving chip for the radio transmitting and receiving chip communication with described card reader that receives MCU, is connected with described reception MCU signal reaches the USB interface for communicating with host computer.
Described card reader also comprises a charging module, and it is for being charged to the battery in card reader.
The frequency of described radio transmitting and receiving chip and reception radio transmitting and receiving chip is: 433MHz, 900MHz, 2.4GHz or 5.8GHz.
Compared with prior art, the utility model possesses following advantage:
1, having wireless and wired two kinds of mode of operations selects;
2, card reader conveniently moving, can displacement far away;
3, more relatively stable than wired in interface stability.
The accompanying drawing explanation
Fig. 1 is the modular structure schematic diagram of the utility model embodiment.
Embodiment
The present embodiment provides a kind of wireless pair of interface card-reading system, and it comprises card reader and Receiver.As shown in Figure 1, described card reader comprises: MCU, it is for controlling Contact Type Ic Card processing module and non-contact IC card processing module and radio transmitting and receiving chip, the Contact Type Ic Card processing module, it is for communicating with the contact card, the non-contact IC card processing module, it is for communicating with non-contact card, radio transmitting and receiving chip, it is for going out data by wireless transmission, the external interrupt device that the contact card inserts, it carries out work for activating MCU, non-ly connect the external interrupt device that the contact card has or not, it carries out work for activating MCU, charging module, it is for being charged to the battery in card reader.Described Receiver comprises that the reception radio transmitting and receiving chip for the radio transmitting and receiving chip communication with described card reader that receives MCU, is connected with described reception MCU signal reaches the USB interface for communicating with host computer.
The present embodiment is based on wireless mode double-interface card reader and computer is coupled together, thereby realizes the operation of host computer to card reader.Wireless operable frequency range has 433MHz, 900MHz, 2.4GHz and 5.8GHz, because present various radio transmitting and receiving chip volumes are very little, so be easy to it is integrated on existing card reader.
In described card reader, battery can be installed, also be provided with charging inlet on card reader simultaneously, if, when the battery in card reader does not have electricity, can be charged to the card reader battery by this charging port.
In order to hold a concurrent post wired card reader pattern, described charging port also has with host computer by the USB interface communication function, thereby holds a concurrent post wired and wireless two kinds of patterns.
Due to the sniffer that is equipped with two kinds of cards of noncontact and contact to have or not on described card reader, it can activate the external interrupt of MCU when contact card or non-contact card occurring, thereby make MCU control two kinds of processing modules, communicates; If can be automatically in sleep pattern in the situation that there is no card, thereby have greatly extended service time of battery.
