Abstract
The utility model discloses a kind of IC-card identification module based on magneto-dependent sensor, described IC-card identification module comprises magneto-dependent sensor, filtering and amplifying circuit, MCU and ATM card inserting mouth structural member; Described ATM card inserting mouth structural member leaves draw-in groove to be passed through for IC-card, and magneto-dependent sensor is installed in the top of structural member.The utility model can identify the IC chip of IC-card sheet, and dependable performance is stablized, and whether effectively can detect the card with IC chip and user when using IC-card with correct direction plug-in card; Be applicable to the card-reading apparatus draw-in grooves such as ATM control to identify application.
Description
Technical field
The utility model relates to a kind of recognition system, in particular, relates to a kind of IC-card sheet recognition system based on magneto-dependent sensor.
Background technology
At present, user often because general idea inserts draw-in groove with the plug-in card direction plug-in card of mistake or the card do not supported by the card-reading apparatus such as ATM when using the card-reading apparatus such as ATM cash dispenser, is spued after ATM identification, is wasted the time, reduced efficiency of service;
There is relevant product can identify the plug-in card direction of magnetic stripe card on the market for magnetic stripe card.
And have for the identification of IC-card sheet the mode identification using contact on the market, but actual use procedure can run into the situation that the impact such as contact damage, IC surface oxidation, dust causes contact and the loose contact of IC chip, and serviceable life is short, and False Rate is high.
Utility model content
The purpose of this utility model is to provide a kind of IC-card identification module based on magneto-dependent sensor, addresses the deficiencies of the prior art.
The technical solution adopted in the utility model is:
A kind of IC-card identification module, comprises magneto-dependent sensor, filtering and amplifying circuit, MCU and ATM card inserting mouth structural member; Described ATM card inserting mouth structural member leaves draw-in groove to be passed through for IC-card, and magneto-dependent sensor is installed in the top of structural member.
Described magneto-dependent sensor is placed on above ATM card inserting mouth structural member, and IC-card is in directly over IC chip after inserting.
The input end of described filtering and amplifying circuit connects magneto-dependent sensor, the magnetosensitive signal after output terminal output processing.
Described magneto-dependent sensor is the one in Hall sensor, MR sensor, GMR sensor, MI sensor.
Chip when user's plug-in card above IC-card sheet is by immediately below magneto-dependent sensor, because IC chip is metallics, the magnetic line of force of the IC chip cutting magneto-dependent sensor of motion, trigger magneto-dependent sensor, the induced signal input filtering and amplifying circuit that magneto-dependent sensor produces after the IC chip of motion triggers, output terminal exports the magnetic susceptibility induction signal after amplification filtering, and MCU receives the magnetic susceptibility induction signal after process, through identifying operation control draw-in groove switch open or closedown.
The beneficial effects of the utility model are: magneto-dependent sensor does not need directly to contact IC-card, belongs to non-contact inductive, and improve induction speed, security is high.
IC-card identification module based on magneto-dependent sensor has gate control function, and only have the IC chip of motion by below magneto-dependent sensor, sensor just can be triggered, and MCU controls draw-in groove switch open, otherwise MCU controls the closedown of draw-in groove switch, and IC-card does not pass through card inserting mouth.Can prevent client from using nonstandard card, and prevent user with the plug-in card mode plug-in card of mistake.

Embodiment
For making the object of the utility model embodiment, technical scheme and advantage clearly understand, below in conjunction with accompanying drawing, the embodiment of the present invention is further described.At this, illustrative examples of the present utility model and illustrate and be used for the utility model, but not as to restriction of the present utility model.
As shown in Figure 1, based on the IC-card identification module of magneto-dependent sensor, electronic system comprises magneto-dependent sensor, filtering and amplifying circuit and MCU.
As shown in Fig. 2, be the structural representation of the IC-card identification module based on magneto-dependent sensor, magneto-dependent sensor 3 is arranged on the top of ATM card inserting mouth 1, is just positioned at directly over IC chip when user's plug-in card 2; Magneto-dependent sensor 3 is electrically connected with PCAB plate 4.
As shown in Figure 3, the IC chip of motion is in (as shown in Figure 4) immediately below magneto-dependent sensor to the trigger theory of the present embodiment, and IC chip 5 cuts the magnetic line of force 6 of magneto-dependent sensor, changes the magnetic resistance of magneto-dependent sensor inside, trigger sensor.
Trigger magneto-dependent sensor after the IC chip cutting magnetic line of force, produce faint induced signal, through the process of filtering and amplifying circuit, its signal waveform exported as shown in Figure 5.
After MCU receives magnetic susceptibility induction signal, through identifying operation control draw-in groove switch open.
Plug-in card mode schematic diagram as shown in Figure 6, plug-in card direction as shown in Figure 7: magneto-dependent sensor is positioned over above ATM card inserting mouth structural member by the present embodiment, and during user's plug-in card, the positive sports-like of IC chip by immediately below magneto-dependent sensor, trigger sensor; If user with the plug-in card mode plug-in card of mistake or institute's plug-in card sheet not containing IC chip, then cannot trigger sensor, ensure that validity and the accuracy of collection.
In a word, aforementioned is preferred implementation of the present utility model, and under the prerequisite not departing from the utility model principle, can also make some improvements and modifications, these improvements and modifications are also considered as protection domain of the present utility model.
