Detailed description of the invention
The present invention is described in further detail in conjunction with accompanying drawing below by detailed description of the invention.
Embodiment one:
Refer to Fig. 1, for the structural representation of the present embodiment non-contact radio frequency cards. The non-contact radio frequency cards of present embodiment includes: main control module, radio-frequency (RF) receiving and transmission module, sensing unit; Described sensing unit is used for gathering the movable information of described non-contact radio frequency cards and producing corresponding data being transferred to described main control module, described main control module judges whether to start described radio-frequency (RF) receiving and transmission module for the data transmitted according to described sensing unit, and described radio-frequency (RF) receiving and transmission module is for carry out rf data mutual with the external world.
User's action when swiping the card is first to accelerate to take out radio-frequency card by radio-frequency card near card reader, then makes card face close to Card Reader in deceleration. Sensing unit in the present embodiment radio-frequency card can gather the kinestate of radio-frequency card always, the movable information of movable information radio-frequency card described above that user card punching is intended to can be embodied may turn on the radio communication function of radio-frequency card when collecting and make radio-frequency card and card reader carry out radio communication, complete the process of swiping the card of user. Embodying, when sensing unit does not collect, the movable information that user card punching is intended to, the radio communication function correspondence with foreign country that will not open radio-frequency card is to close. User's radio-frequency card when not swiping the card intention thus it is possible to prevent to steal brush.
Collaborative work between all right control card of main control module in the present embodiment each functional module interior. The non-contact radio frequency cards of certain the present embodiment can include the functional module that some are common. If radio-frequency card interface module is for realizing the connection with other equipment, radio-frequency card controls module for realizing the additional function of radio-frequency card.
As shown in Figure 2, in the present embodiment, non-contact radio frequency cards can arrange three axle acceleration sensors in sensing unit and obtain the described non-contact radio frequency cards acceleration information in tri-directions of solid axes X, Y, Z, and transmit corresponding data to main control module, main control module by these about the data of acceleration by obtaining the information such as speed and the position of radio-frequency card after mathematical operation, and the speed and positional information according to radio-frequency card judges whether identification user has the intention swiped the card. as shown in Figure 3, the non-contact radio frequency cards of the present embodiment also can be provided with this more accurate sensor of three-axis gyroscope sensor, three-axis gyroscope sensor can obtain radio-frequency card at solid axes X, Y, the angular velocity in tri-directions of Z, corresponding data be transmitted to main control module after angular velocity being detected, main control module processes, to pulling a little data about angular velocity, the actual motion data drawing radio-frequency card, then judge whether user swipes the card intention according to the data after processing, the intention if user swipes the card, the communication function opening radio-frequency card carries out radio communication with card reader, as fruit tree has the state keeping correspondence with foreign country to close. also can by three axle acceleration sensors of course for the actual motion information that can collect radio-frequency card more accurately, three-axis gyroscope sensor is simultaneously located in sensing unit, as shown in Figure 4, three axle acceleration sensors, three-axis gyroscope sensor gathers the actual motion information of radio-frequency card simultaneously, each transmit data to main control module, then main control module the data of the two transmission are processed single process or collect together process obtain the radio-frequency card data about radio-frequency card speed and position, and judge to identify whether user swipes the card intention according to these data, there is then unlatching radio communication function, the state then not remained turned-off.
For the movable information accurately making radio-frequency card to obtain, multiple different sensor can be set in sensing unit, such as electronic compass, obliquity sensor etc., the kind of sensor arranged is more many, and the movable information that radio frequency obtains is more abundant, identifies that the accuracy of user card punching action is more high. The radio-frequency card of the present embodiment can be constantly in closed mode before user card punching, only when radio-frequency card senses the operating state swiped the card, just can open radio-frequency card radio communication function; If radio-frequency card does not sense the movable information swiped the card, then can be always maintained at closed mode, to prevent the stolen brush of radio-frequency card.
When radio-frequency card opens radio communication function, but user does not swipe the card for a long time, and radio-frequency card can be made to be constantly in state of activation, thus the safety problem of the radio-frequency card produced. In order to prevent the generation of above-mentioned situation from can arrange intervalometer in the present embodiment non-contact radio frequency cards, as shown in Figure 5, intervalometer is preset a maximum functional and allows the time, opening timing device while of when radio-frequency card opens radio communication function, intervalometer starts accumulation interval, when the cumulative time reaches preset maximum value, close the radio communication function of radio-frequency card.
Embodiment two:
It is illustrated in figure 6 the block flow diagram of the method for work that the present embodiment is non-contact radio frequency cards. The method of work of this enforcement non-contact radio frequency cards comprises the steps:
