Embodiment
The automatic test table of smart card comprises smart card reader, also is provided with embedded controller, light-coupled isolation module, power amplifier module, stepper motor and turntable.Embedded controller is selected STC89C52 type single-chip microcomputer in the present embodiment, and the light-coupled isolation module is selected TLP521-4 type photoelectric isolated chip, and power amplifier module is selected L298 type power amplification chip, and stepper motor adopts 23L-C331-08 model stepper motor.
4 road I/O ports of the P1.0～P1.3 of STC89C52 type single-chip microcomputer are as the output port of control signal.Shown in figure (3), the P1.0 of STC89C52 type single-chip microcomputer～P1.3 pin is connected to diode D1～D4, and diode D1～D4 is by drawing exclusion R-4 to be connected to the 5V power supply on the 10K Ω.Simultaneously, P1.0～P1.3 pin is connected to socket HEADER as output terminal.
Shown in figure (4); four road signals of STC89C52 type single-chip microcomputer output; be that 4 tunnel of P1.0～P1.3 exports the input end that connects TLP521-4 light-coupled isolation chip; i.e. 2 pin, 4 pin, 6 pin, 8 pin; realize effective isolation of strong power part and weak current part; thereby to weak current part, namely Single-chip Controlling partly plays a protective role.L298 type power amplification chip is the bridge stepper motor special driving chip of enjoying a double blessing, and this chip is the special purpose driver of a kind of two-phase and four phase step motor, can drive four phase step motor.Shown in figure (4), (5), (6), four road signals of TLP521-4 light-coupled isolation chip output, be CW/CCW, HALF/FU LL, CLK, RST, be connected to respectively input end IN1, IN2, IN3, the IN4 of L298N chip by wire jumper, four line input ends of output OUT1, the OUT2 of L298N chip, OUT3, OUT4 four tunnel drive control signal access stepper motor, Driving Stepping Motor rotates.Shown in figure (6), the diode D1～D8 that is connected in parallel on the L298 output terminal plays the afterflow protective effect.
Stepper motor is fixed on the stable plane, guarantees that motor itself does not cause autobiography because of moment of inertia.
Turntable is 20 centimetres by the bottom surface diameter, high 5 centimetres cylindrical shape abutment body, central shaft and 8 intelligent draw-in grooves formations that are evenly distributed on the abutment body lateral wall, and intelligent draw-in groove can also be arranged to 10,12,14 according to size and the special requirement of abutment body girth ... individual etc.The center of abutment body bottom surface is connected by pin or engage thread with motor shaft, also can adopt bonding or other connected modes of hot melt adhesive.Abutment body and smart card draw-in groove are paid the utmost attention to qualitative factor under the requirement of satisfying profile, the abutment body that quality is little is easier to drive, and help to improve stability.
There is not physical connection between intelligent card reader and the turntable module, but with the relative position of the stability plane at motor place certain requirement is arranged: the induction zone of card reader is fixed on the position tangent with the turntable lateral wall, but the gap certain with the draw-in groove maintenance is so that turntable can smooth and easyly turn round.Card reader when test with the continuous outside emitting electromagnetic wave of the mode of poll, when having intelligent cards to be measured to enter the electromagnetism place of some strength, smart card to be measured will solve the instruction that provides in the agreement from the electromagnetic wave of card reader emission, and replys corresponding instruction to card reader.At this moment, after card reader receives the instruction of smart card answer to be measured, can read the numbering of smart card to be measured, and carry out the instruction that sets in the test event, smart card be carried out the test of interactivity.When all tests were all passed through, card reader will send to computer to the numbering of smart card to be measured and smart card to be measured by the information of testing.In test process, any one test by the time, card reader will be ended test, and will open smart card to be measured numbering, appearance the corresponding instruction of problem and not the reason by test send to computer, prepare against processing.The polling system of card reader software section also is one of main points of whole system normal operation, if software is not supported poll, then needs manual operation PC to realize control to test.
In whole testing fatigue process, computer and card reader are carried out real-time, interactive.After the card reader smart card to be measured interior with placing intelligent draw-in groove carried out alternately, card reader was transferred to computer with test result by USB interface, and computer is directly with outcome record, and input database, in order to follow-up finishing analysis.Simultaneously, computer operates card reader in the beginning of whole test job with when finishing, and sends corresponding instruction, realize to electromagnetic field unlatching, close, the work such as the transmission of data, reception.
STC89C52 type single-chip microcomputer uses the C Programming with Pascal Language, controls the motor operation, stops and speed governing by the adjustable periodic square wave signal of programmed control single-chip microcomputer output frequency.
1, operation: in order to guarantee rotating torque and higher running precision, Single Chip Microcomputer (SCM) program control step machine operation is under 8 bat patterns.8 bat mode of operations are that 8 square-wave cycle are as a motor cycle of operation.In the cycle of operation, single-chip microcomputer is exported 4 tunnel different square wave sequences at a motor.Single-chip microcomputer circulation output
The whole cycle of operationSquare-wave signal, make motor keep rotating continuously.
2, stop: when single-chip microcomputer stops periodically gating pulse of output, motor stalling.
3, speed governing: adopt two kinds of method associating speed governing.1. by prolonging or shorten controlling party wave period, can change from bottom the rotating speed of motor.2. insert the time interval that makes motor stalling between the cycle of operation at each motor, and finely tune stall interlude length by the mode of timing, thereby reach the adjusting to motor overall operation speed.
According to the requirement of smart card test, set the parameters such as travelling speed, stall interval of motor during application, finish automatic test job to cooperate smart card reader.
