Accompanying drawing explanation
Fig. 1 is that the structure of the better embodiment of a kind of Card Reader distance measurement system based on RFID-SIM card of the present invention is shown
It is intended to；And
Fig. 2 is the flow chart of a kind of Card Reader distance measurement method based on RFID-SIM card of the present invention.
Detailed description of the invention
The present invention proposes a kind of Card Reader distance measurement system based on RFID-SIM card applied in mobile payment field
And method.
Refer to the preferable embodiment party that Fig. 1, Fig. 1 are a kind of Card Reader distance measurement systems based on RFID-SIM card of the present invention
The structural representation of formula.Card Reader distance measurement system 1 includes card reader 10 and mobile terminal 20.
Card reader 10 includes controller 101, abnormal smells from the patient generation module 103 and the first wireless communication module (not shown), controls
Device 101 controls abnormal smells from the patient generation module 103 and produces escaping gas, and the concentration of escaping gas has the characteristic with range attenuation.
When external equipment carries out radio-frequency communication with card reader 10, card reader 10 produces escaping gas by abnormal smells from the patient generation module 103,
External equipment is acquired and detects the concentration parameter of escaping gas to escaping gas, and then obtains between card reader 10
Card Reader range information.E.g. a kind of vaporizer of abnormal smells from the patient generation module 103 or nebulizer.
Mobile terminal 20 includes odor detection module 201, RFID-SIM card 203 and the second wireless communication module, and (figure is not
Show), RFID-SIM card 203 and card reader 10 carry out radio-frequency communication, and odor detection module 201 and RFID-SIM card 203 electrically connects,
Mobile terminal 20 storage has the concentration parameter of the escaping gas of detection and the concentration ginseng of calibrating parameters comparison escaping gas
Number and calibrating parameters.Card reader 10 and mobile terminal 20 can be carried out by the first wireless communication module and the second wireless communication module
Communication.
Odor detection module 201 includes abnormal smells from the patient sampling operation device (not shown), gas sensor array (not shown) and letter
Number processing system.Odor detection module 201 main operational principle is that tested gas is had by each gas sensor in array
Different sensitivity, such as, a gas can produce high response on certain gas sensor, to other gas sensors then
Being low-response, equally, the sensor of No. two gas height responses is the most insensitive to a gas.
Specifically, first, utilize vacuum pump that air sampling is drawn to equipped with in the small container of electronic sensor array；
Then, sampling operation unit is exposed to initialized gas sensor array in abnormal smells from the patient body, when volatile compound and biography
When sensor surface of active material contacts, just produce transient response；Finally, alcohol steam to be used " rinses " sensor activation material
The admixture of gas that surface is complete to remove detection.
Wherein, when mobile terminal 20 carries out radio-frequency communication by RFID-SIM card 203 with card reader 10, card reader 10 is led to
Crossing abnormal smells from the patient generation module 103 and produce escaping gas, escaping gas is carried out by mobile terminal 20 by odor detection module 201
Gathering and detect the concentration parameter of escaping gas, the concentration parameter of the escaping gas obtained is joined by mobile terminal 20 with demarcating
Number is compared, and obtains the Card Reader range information between mobile terminal 20 and card reader 10 according to comparison result.
Specifically, during mobile payment, opening card reader 10, the controller 101 of card reader 10 can be according to concrete needs
Control abnormal smells from the patient generation module 103 and produce corresponding escaping gas, when mobile terminal 20 is positioned at the volatility that reading card device 10 produces
Within the scope of gas concentration, startup is detected by the odor detection module 201 of mobile terminal 20, the odor detection mould of mobile terminal 20
Block 201 just can detect concentration and the direction of the escaping gas that abnormal smells from the patient generation module 103 produces.And escaping gas is dense
Relation between degree and distance can be by calculated, thus detects the concentration parameter of escaping gas, and will visit
The concentration parameter measuring escaping gas is stored in mobile terminal 20, and such mobile terminal 20 just can be the volatility detected
The concentration parameter of gas and be previously stored in the calibrating parameters within mobile terminal 10 and compare, thus obtain mobile terminal 20
And the range information between card reader 10.Card Reader range information is compared by Card Reader distance measurement system 1 with setpoint distance, enters
And judging whether to meet between mobile terminal 20 and card reader 10 safety communication distance, RFID-SIM card 203 will be according to distance letter
Breath judges whether to next step communication operation.
Refer to the flow chart that Fig. 2, Fig. 2 are a kind of Card Reader distance measurement methods based on RFID-SIM card of the present invention.This
Invent Card Reader distance measurement method based on RFID-SIM card 203 to comprise the following steps:
S1. escaping gas is produced；
S2. gather escaping gas and detect the concentration parameter of escaping gas；
S3. the concentration parameter of escaping gas is compared with calibrating parameters, with according to comparison result obtain Card Reader away from
From information.
Wherein, in step S2, first pass through card reader 10 and control abnormal smells from the patient generation module 103 and produce escaping gas, by gas
The escaping gas that abnormal smells from the patient generation module 103 is produced by taste detecting module 201 is acquired detecting the concentration of escaping gas
Parameter；In step S3, the concentration parameter of the escaping gas detected will be stored in mobile terminal 20 mark internal with it
Determine parameter to compare, to obtain the range information between mobile terminal 20 and card reader 10 according to comparison result.
Within mobile terminal 20 is positioned at the concentration range of escaping gas, the odor detection module 201 of mobile terminal 20
Startup is detected.After obtaining the range information between mobile terminal 20 and card reader 10, by Card Reader range information and setpoint distance
Compare, and then judge whether Card Reader distance meets safety communication distance.
In sum, in a kind of based on RFID-SIM card the Card Reader distance measurement system and method for the present invention, by visiting
The method surveying the distance between mobile terminal and card reader solves the secure payment during RFID-SIM card mobile payment
Problem, can complete mobile payment transaction task, it is ensured that transaction security is carried out well, and safety is high.
The foregoing is only embodiments of the invention, not thereby limit the scope of the claims of the present invention, every utilize this
Equivalent structure or equivalence flow process that bright description and accompanying drawing content are made convert, or are directly or indirectly used in other relevant skills
