[embodiment]
In order to understand the present invention better, below with reference to accompanying drawing and instantiation, the present invention will be described in detail.
Incorporated by reference to consulting Fig. 1 and Fig. 2, the contactless smart card 100 of what the preferred embodiment of the present invention provided have loss prevention function comprises control module 10, smart card module 20 and anti-lost module 30, and smart card module 20 and anti-lost module 30 are all connected to control module 10.Control module 10 is the whole centralized control part with the contactless smart card 100 of loss prevention function, realizes controlling respectively smart card module 20 and anti-lost module 30.Smart card module 20 is whole parts with the basic contactless smart card function of middle realization of the contactless smart card 100 of loss prevention function, stores relevant information, can respond to card reader 200 noncontact, performs operation of swiping the card.Anti-lost module 30 performs to contactless smart card 100 part found and prevent loss, and it is connected with Bluetooth terminal 300 by bluetooth approach, realizes anti-lost.
Specifically, control module 10 comprises MCU (Micro Control Unit) control chip 12, power supply 14, display screen 16 and function button 18.MCU control chip 12 is the core of control module, and it is connected with smart card module 20 and anti-lost module 30 respectively, realizes the control to smart card module 20 and anti-lost module 30.Power supply 14 is connected to MCU control chip 12, provides electric power support by MCU control chip 12 for needing the part of powering in whole contactless smart card 100.Display screen 16, function button 18 are connected to MCU control chip 12 respectively, show information and key entry information respectively under the control of MCU control chip 12.
Smart card module 20 comprises SE (Secure Element) chip 22 and RFID antenna 24.SE chip 22 is connected to MCU control chip 12, controls by it.Have secure data information in SE chip 22, RFID antenna 24 for being connected to the noncontact antenna of SE chip 22, for send and received RF signal.Secure data information in SE chip 22 is read rear execution by RFID antenna 24 by card reader 200 and operates accordingly.
Anti-lost module 30 comprises Bluetooth chip 32, Bluetooth antenna 34, warning light 36 and hummer 38.Bluetooth chip 32 is connected to MCU control chip 12, controls by it.Bluetooth antenna 34, for being connected to the antenna of Bluetooth chip 32, sets up the connection of Bluetooth chip 32 and Bluetooth terminal 300.Warning light 36 and hummer 38 are connected to Bluetooth chip 32, under the control of MCU control chip 12, and Bluetooth chip 32 selectively unlocking warning light 36 and/or hummer 38.
The above-mentioned contactless smart card 100 with loss prevention function has two states, normal state and anti-lost state.
Under normal conditions, anti-lost module 30 does not power on, bluetooth connection closed, and contactless smart card 100 and common contactless smart card use and be as good as, and contactless smart card 100 can be realized Card Reader near card reader 200.
When being switched to anti-lost state from normal state, press contactless smart card 100 upper end function button 18, power supply 14 starts as contactless smart card 100 is powered, and bluetooth is opened, and connects with Bluetooth terminal 300.
Under anti-lost state, Bluetooth terminal 300 can be contactless smart card 100 and arranges safe distance, distance is therebetween calculated according to the intensity (RSSI, Received Signal Strength Indication) of bluetooth connection signal between Bluetooth terminal 300 and contactless smart card 100.The time in that calculating distance between contactless smart card 100 and Bluetooth terminal 300 exceeding default safe distance, start warning light 36 and hummer 38, warning light 36 glimmers, and hummer 38 sends chimes of doom.Under anti-lost state, also can realize initiatively looking for.Even if the calculating distance between contactless smart card 100 and Bluetooth terminal 300 exceed default safe distance in situation, also start warning light 36 and hummer 38 by the operation on Bluetooth terminal 300, conveniently to find.
Refer to Fig. 2, it is the workflow schematic diagram with the contactless smart card 100 of loss prevention function of the present invention.
Step S1, contactless smart card powers on, anti-lost module work, and bluetooth is opened.When contactless smart card 100 powers on, power supply 14 starts as contactless smart card 100 is powered.After Bluetooth chip 32 powers on, send Bluetooth signal by Bluetooth antenna 34.
Step S2, contactless smart card is connected by bluetooth and Bluetooth terminal.The Bluetooth signal sent by Bluetooth antenna 34 when Bluetooth chip 32 is searched by Bluetooth terminal 300 and after the match is successful, contactless smart card 100 is set up bluetooth with Bluetooth terminal 300 and is connected.
Step S3, the data of card correlation circumstance are sent to Bluetooth terminal by contactless smart card.Relevant data are sent to Bluetooth terminal 300 by contactless smart card 100, and Bluetooth terminal 300 shows the information of relevant contactless smart card 100.Bluetooth terminal 300 according to relevant information arrange preset security distance, type of alarm (warning light flicker, buzzer warning or the two use simultaneously) etc. parameter.
Step S4, judges whether the distance between contactless smart card and Bluetooth terminal exceedes default safe distance.Bluetooth terminal 300 calculates the distance between contactless smart card 100 according to bluetooth connection signal intensity, thinks that contactless smart card 100 is not lost in safe distance.
Step S5, starts warning light and the hummer of contactless smart card.The time in that distance between contactless smart card 100 Bluetooth terminal 300 calculated according to bluetooth connection signal intensity exceeding default safe distance, according to the type of alarm preset (warning light flicker, buzzer warning or the two use simultaneously) start warning light 36 and the hummer 38 of contactless smart card.
In other embodiments, contactless smart card also can not arrange the alarm such as warning light and hummer, but reports to the police by Bluetooth terminal self, such as: utilize jingle bell, vibrations etc. to point out and report to the police.
Compared with prior art, contactless smart card of the present invention at least has the advantage of the following aspects:
(1) contactless smart card of the present invention arranges anti-lost module by inside and can set up bluetooth with Bluetooth terminal and be connected, then plays loss prevention function by warning light, hummer, solves the problem that smart card is not easy to carry, easily lose.
(2) contactless smart card of the present invention arranges by inside that anti-lost module starts warning light by Bluetooth terminal, hummer realizes initiatively looking up function, and the practicality for contactless smart card brings conveniently.
(3) the Bluetooth signal intensity (RSSI) when contactless smart card of the present invention is to communicate is with reference to calculating distance by filtering algorithm, and personalizable arranges preset security distance, applied widely.
The above exemplifying embodiment only have expressed some embodiments of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
