以下依序對低頻感應卡讀取、低頻感應卡模擬、高頻感應卡卡號與資料讀取、高頻感應卡模擬作詳細的說明。 The following is a detailed description of the low frequency induction card reading, the low frequency induction card simulation, the high frequency induction card number and data reading, and the high frequency induction card simulation.
首先對感應卡學習裝置讀取低頻感應卡的方法(學習模式)進行說明。請參閱圖10。圖10為圖2實施例之感應卡學習裝 置10的腳位I/O Port 1與腳位I/O Port 2未接上線圈12的波形圖。波形P1001為腳位I/O Port 1的電壓。波型P1002為腳位I/O Port 2的電壓。微控制器11先以載波的頻率從腳位I/O Port 1與腳位I/O Port 2輸出方波，方波的頻率約為125kHz，週期約為8μs。 First, a method (learning mode) in which the proximity card learning device reads the low frequency proximity card will be described. Please refer to Figure 10. Figure 10 is a simulation card learning device of the embodiment of Figure 2. The pin diagram of pin 10 I/O Port 1 and pin I/O Port 2 is not connected to the waveform of coil 12. Waveform P1001 is the voltage of pin I/O Port 1. Waveform P1002 is the voltage of pin I/O Port 2. The microcontroller 11 first outputs a square wave from the pin I/O Port 1 and the pin I/O Port 2 at the carrier frequency. The square wave has a frequency of about 125 kHz and a period of about 8 μs.
接下來請參閱圖11。圖11為圖2實施例之感應卡學習裝置10腳位I/O Port 1與腳位I/O Port 2接上線圈12的波形圖。在本實施例中，微控制器11將電壓下拉至低電位的能力大於電壓上拉至高電位的能力。故當腳位I/O Port 1與腳位I/O Port 2其中一腳位輸出低電位，而另一腳位輸出高電位時，在短暫時間後輸出高電位的腳位I/O Port 1或腳位I/O Port 2的電壓會被下拉到低電位。在圖11由虛線所圍起來的區塊b1101，即在說明當腳位I/O Port 1的電壓P1001下拉至低電位時，則腳位I/O Port 2的電壓P1002也會受腳位I/O Port 1的電壓P1001影響而從高電位被下拉至低電位。 See Figure 11 next. FIG. 11 is a waveform diagram of the pin card I/O Port 1 and the pin I/O Port 2 connected to the coil 12 of the proximity card learning device of the embodiment of FIG. In this embodiment, the ability of the microcontroller 11 to pull the voltage down to a low potential is greater than the ability of the voltage to pull up to a high potential. Therefore, when the pin I/O Port 1 and the pin I/O Port 2 output a low potential, and the other pin outputs a high potential, the high potential pin I/O Port 1 is output after a short time. Or the pin I/O Port 2 voltage will be pulled down to low. In block 11 of FIG. 11 surrounded by a broken line, that is, when the voltage P1001 of the pin I/O Port 1 is pulled down to a low level, the voltage P1002 of the pin I/O Port 2 is also affected by the pin I. /O Port 1 voltage P1001 is affected and pulled from high potential to low potential.
圖12是圖11區塊b1101的放大圖。請參閱圖12，腳位I/O Port 2的電壓P1002下降的速度與負載阻抗的大小有關。負載阻抗由線圈12與被讀取的感應卡的內部電路相關。本發明在腳位I/O Port 1的電壓P1001下拉至低電位時，啟動類比數位轉換功能。另外由I/O Port 2的電壓P1002從高電位下降到低電位的斜率，也就是壓降a2除以時間a1的值可判斷負載阻抗大小，當壓降a2除以時間a1的值愈大，也就是斜率愈大，則代表負載阻抗愈大。圖13表示圖2實施例未讀取到感應卡時，腳位ADC Input 將輸入的類比訊號轉換成數位訊號的數值。當未讀取到感應卡時，得到的數位訊號數值為「52」或「51」，變化幅度很小。圖14表示圖2實施例讀取到感應卡時，腳位ADC Input將輸入的類比訊號轉換成數位訊號的數值。區塊b1401為標頭(header)，其長度在此實施例中為9位元(Bit)，顯示的數值為連續9個「1」，當得到標頭時，再依照低頻感應卡的傳輸格式進行資料解碼，轉換成如區塊b1402所示的卡號。 Figure 12 is an enlarged view of block b1101 of Figure 11. Referring to FIG. 12, the speed at which the voltage P1002 of the pin I/O Port 2 falls is related to the magnitude of the load impedance. The load impedance is related to the internal circuitry of the sense card being read by the coil 12. The present invention activates the analog digital conversion function when the voltage P1001 of the pin I/O Port 1 is pulled down to a low potential. In addition, the slope of the voltage P1002 of the I/O Port 2 from the high potential to the low potential, that is, the voltage drop a2 divided by the value of the time a1 can determine the magnitude of the load impedance, and the larger the value of the voltage drop a2 divided by the time a1, That is, the larger the slope, the greater the load impedance. Figure 13 shows the pin ADC Input when the inductive card is not read in the embodiment of Figure 2. Convert the input analog signal to the value of the digital signal. When the proximity card is not read, the resulting digital signal value is "52" or "51" with a small change. FIG. 14 shows the value of the ADC ADC Input converting the input analog signal into a digital signal when the sensing card is read in the embodiment of FIG. 2. The block b1401 is a header, and its length is 9 bits in this embodiment, and the displayed value is 9 consecutive "1"s. When the header is obtained, the transmission format of the low-frequency proximity card is followed. The data is decoded and converted into a card number as shown in block b1402.
接下來對感應卡學習裝置模擬低頻感應卡的方法(一般 模式)進行說明。以圖2實施例的感應卡學習裝置作說明。將腳位I/O Port 1與腳位I/O Port 2設成輸入埠，並啟用I/O Port喚醒微控制器11功能。在接近感應卡讀卡機時，I/O Port接收到感應卡讀卡機的載波信號高低變化，而將微控制器11喚醒。微控制器11再依照載波頻率判斷。若為低頻時，依照傳輸格式及時序，設定腳位I/O Port 1與腳位I/O Port 2為輸入埠或輸出埠，再與連結的線圈12形成變化的負載，將卡號資料傳送給感應卡讀卡機。 Next, a method of simulating a low frequency proximity card for a proximity card learning device (generally Mode) for explanation. The induction card learning device of the embodiment of Fig. 2 will be described. Set pin I/O Port 1 and pin I/O Port 2 to input 埠 and enable I/O Port to wake up the microcontroller 11 function. When approaching the proximity card reader, the I/O Port receives the change in the carrier signal of the proximity card reader and wakes up the microcontroller 11. The microcontroller 11 then judges according to the carrier frequency. If it is low frequency, according to the transmission format and timing, set the pin I/O Port 1 and the pin I/O Port 2 as the input port or output port, and then form a varying load with the connected coil 12, and transmit the card number data to Proximity card reader.

Figure 15 voltage waveform P1001 from pin I/O Port 1 The voltage waveform P1002 of the pin I/O Port 2 is used to see the digital signal value of the analog low frequency proximity card. Block b1501 is the header. When the voltage P1001 of the pin I/O Port 1 is pulled from the high amplitude to the low amplitude, it represents that the binary bit is "1", and when the low amplitude is pulled to the high amplitude, the binary bit is represented as "0".

At the time point t1 of Fig. 17, when the voltage P1602 of the pin PWM Output Port starts to change, the voltage P1601 of the pin I/O Port 2 also changes. FIG. 18 shows that the microcontroller 11 controls the output pulse width modulation signal of the PWM output port according to the transmission format.

At the time points t1 to t2 of Fig. 24, it is indicated that the microcontroller 11 transmits the SELECT command, and at the time point t3 to t4, the waveform of the induction card return card number (UID) is received, wherein in Fig. 24, the sensing is performed.
