Embodiment
The present invention proposes a kind of Card Reader distance measurement system and method based on the RFID-SIM card that is applied in the mobile payment field.
See also Fig. 1, Fig. 1 is the structural representation of the better embodiment of the present invention a kind of Card Reader distance measurement system based on the RFID-SIM card.Card Reader distance measurement system 1 comprises card reader 10 and mobile terminal 20.
Card reader 10 comprises controller 101, smell generation module 103 and the first wireless communication module (not shown), and controller 101 is controlled smell generation module 103 and produced escaping gas, and the concentration of escaping gas has the characteristic with range attenuation.When external unit and card reader 10 are carried out radio-frequency communication, card reader 10 produces escaping gas by smell generation module 103, external unit gathers and surveys the concentration parameter of escaping gas to escaping gas, and then the Card Reader range information between acquisition and card reader 10.Smell generation module 103 is for example a kind of evaporator or atomizer.
Mobile terminal 20 comprises smell detecting module 201, RFID-SIM card 203 and the second wireless communication module (not shown), RFID-SIM card 203 carries out radio-frequency communication with card reader 10, smell detecting module 201 and RFID-SIM card 203 is electrically connected to, mobile terminal 20 store detection escaping gas concentration parameter and calibrating parameters and compare concentration parameter and the calibrating parameters of escaping gas.Card reader 10 and mobile terminal 20 can carry out communication by the first wireless communication module and the second wireless communication module.
Smell detecting module 201 comprises smell sampling operation device (not shown), gas sensor array (not shown) and signal processing system.Smell detecting module 201 groundwork principles are that each gas sensor in array has different sensitivity to tested gas, for example, No. one gas can produce high response on certain gas sensor, low-response to other gas sensors, equally, the sensor of No. two high responses of gas is insensitive to a gas.
Particularly, at first, utilize vacuum pump that air sampling is drawn to the small container that the electronic sensor array is housed; Then, the sampling operation unit is exposed to initialized gas sensor array in the smell body, when volatile compound contacts with the sensor surface of active material, just produces transient response; At last, use alcohol steam " flushing " sensor surface of active material to survey complete gaseous mixture to remove.
Wherein, when mobile terminal 20 carries out radio-frequency communication by RFID-SIM card 203 and card reader 10, card reader 10 produces escaping gas by smell generation module 103, mobile terminal 20 gathers and surveys the concentration parameter of escaping gas by 201 pairs of escaping gases of smell detecting module, mobile terminal 20 is compared concentration parameter and the calibrating parameters of the escaping gas that obtains, obtains Card Reader range information between mobile terminal 20 and card reader 10 according to comparison result.
Particularly, during mobile payment, open card reader 10, the controller 101 of card reader 10 can be controlled smell generation module 103 according to concrete needs and produce corresponding escaping gas, be positioned at the escaping gas concentration range of reading card device 10 generations when mobile terminal 20 within, the smell detecting module 201 of mobile terminal 20 will start detection, and the smell detecting module 201 of mobile terminal 20 just can detect concentration and the direction of the escaping gas of smell generation module 103 generations.And the relation between the concentration of escaping gas and distance can be by calculating, thereby detect the concentration parameter of escaping gas, and the concentration parameter that will detect escaping gas is stored in mobile terminal 20, mobile terminal 20 just can be compared the concentration parameter of the escaping gas that detects and the calibrating parameters that is stored in advance mobile terminal 10 inside like this, thereby obtains the range information between mobile terminal 20 and card reader 10.Card Reader distance measurement system 1 compares Card Reader range information and setpoint distance, and then judging between mobile terminal 20 and card reader 10 whether meet the safety communication distance, RFID-SIM card 203 will judge whether to carry out according to range information next step communication operation.
See also Fig. 2, Fig. 2 is the process flow diagram of a kind of Card Reader distance measurement method based on the RFID-SIM card of the present invention.The Card Reader distance measurement method that the present invention is based on RFID-SIM card 203 comprises the following steps:
S1. produce escaping gas;
S2. gather escaping gas and survey the concentration parameter of escaping gas;
S3. concentration parameter and the calibrating parameters of escaping gas are compared, to obtain the Card Reader range information according to comparison result.
Wherein, in step S2, at first control smell generation module 103 by card reader 10 and produce escaping gas, surveyed the concentration parameter of escaping gas by the escaping gas collection of 201 pairs of smell generation modules of smell detecting module, 103 generations; In step S3, the concentration parameter of the escaping gas that detects will be stored in mobile terminal 20 and the calibrating parameters inner with it compared, to obtain the range information between mobile terminal 20 and card reader 10 according to comparison result.
Be positioned at the concentration range of escaping gas when mobile terminal 20 within, the smell detecting module 201 of mobile terminal 20 will start detection.After obtaining the range information between mobile terminal 20 and card reader 10, Card Reader range information and setpoint distance are compared, and then judge whether the Card Reader distance meets the safety communication distance.
