Module：

TC35i new editions Siemens industry gsm module is a technical grade gsm module for supporting Chinese short message breath, is operated in EGSM900 and GSM1800 two-bands, power range are direct current 3.3V~4.8V, current drain --- resting state 3.5mA, Idle condition is 25mA, and emission state is 300mA (average), 2.5A peak values；Voice-and-data signal can be transmitted, power consumption exists EGSM900 (4 class) and GSM1800 (1 class) is respectively 2W and 1W, and SIM is connected respectively by interface connector and antenna connector Card reader and antenna.SIM voltages are 3V/1.8V, and TC35i data-interface (CMOS level) can transmitted in both directions by AT orders Instruction and data, optional baud rate are 300b/s~115kb/s, and auto-baud is 1.2kb/s~115kb/s.It is supported The SMS (Short Message Service, short message) of Text and PDU forms, weight can be realized by AT orders or cut-off signals Open and fault recovery.

TC35i has 40 pins as shown in Figure 5.This 40 pins can be divided into 5 classes, i.e. power supply, data input/defeated Go out, SIM card, COBBAIF and control.The pin of chip is described below：

1~5 pin：The usual recommendation 4.2V of positive supply input pin.

6~10 pins：Earth terminal.

11st, 12 pin：Charging, can be with external lithium battery.

13 pins：For external output voltage (external circuit use altogether).

14 pins：The thermistor of negative temperature coefficient is connect for ACCU-TEMP, protects and controls for lithium cell charging.

15 pins：Start pin IGT, be TC35i is entered working condition after system power-up, it is necessary to be more than to IGT plus one 100ms low pulse, level decline duration may not exceed 1ms.

16~23 pins：Data input/output, respectively DSR0, RING0, RxD0, TxD0, CTS0, RTS0, DTR0 and DCD0。

24~29 pins：TC35i uses circumscribed SIM card, and CCRST, CCIO, CCCL, CCVCC and CCGND on SIM lead to The Same Name of Ends for crossing SIM card reader and TC35i is joined directly together.

30~32 pins：Pin is controlled, wherein 30 be RTC backup, 31 be Power down, and 32 be SYNC.35~38 Pin：Speech interface.35th, 36 pin connect loudspeaker playback, and 37,38 pin can directly catch microphone to gather sound.

As shown in fig. 6, one-chip machine port P3.0 be pin 10 and P3.1 be pin 11 respectively with TC35i pins 18 and pin 19 connections.

Reset oscillating circuit：

It is as shown in Figure 7 and Figure 8 the clock circuit part and reset circuit part of reset oscillating circuit.Inside STC89C52 There is a high gain inverting amplifier for being used to form oscillator, pin XTAL1 and XTAL2 are the input of this amplifier respectively With the pin of output end, outside single-chip microcomputer and quartz oscillator and two capacitor C are connect by the two pins₂And C₃.Stone English crystal produces clock as timing element, internal inverted amplifier self-oscillation, and clock generator divides oscillating impulse two Frequently, circuit uses 22pF electric capacity, and clock pulses is produced using 11.092MHz crystal oscillator.

RST pins are reset signal inputs, and high level is effective.Powered on moment RST pins obtain high level, with electric capacity C1 charging, the high level of RST pins will be gradually reduced.The design uses upper electric hand-reset, if system goes wrong, presses Lower button can reset.

Buzzer circuit：

As shown in figure 9, the usual operating current of buzzer is bigger, the Transistor-Transistor Logic level on circuit does not drive buzzing substantially Device is, it is necessary to which the circuit for increasing a Current amplifier just can be with so add a triode to increase the electricity by buzzer Stream.One end ground connection of buzzer, the emitter stage of another termination triode, the ground level of triode are controlled by the P1.5 pins of single-chip microcomputer System.User can set low and put height to make buzzer send sound and closing by programme-control P1.5 pins.

Unlocking control circuit：

As shown in Figure 10, the input termination P1.4 pins of the relay of unlocking circuit, when the password and deposit that receive are single When the password of piece machine is consistent, when it is low level that P1.4 pins, which are the low level i.e. base stage of triode, triode ON, relay Work, unlock.When P1.4 pins are high level, triode cut-off, relay does not work.

Liquid crystal display circuit：

As shown in figure 11, LCD liquid crystal displays are Liquid Crystal Display abbreviations, LCD construction It is the crystal that liquid is placed among the parallel glass of two panels, there are many tiny electric wires vertically and horizontally among two sheet glass, Shaft-like crystal molecular changes direction is controlled through whether being powered, light is reflected into generation picture.Used in the design LCDs model LCD1602.LCD1602 is industrial character mode lcd, can show 16x2 i.e. 32 character simultaneously（16 The row of row 2）.

1602 use 16 pin interfaces of standard, wherein：

1st pin：VSS is for power supply；

2nd pin：VDD connects 5V positive sources；

3rd pin：V0 is liquid crystal display setting contrast end, and contrast is most weak when connecing positive supply, is contrasted during earthing power supply Spend highest；

4th pin：RS is register selection, selection instruction register when selecting data register, low level 0 during high level 1；

5th pin：RW is reading writing signal line, carries out read operation during high level (1), carries out write operation during low level (0).

Can be with write instruction or display address, when RS is that low level RW is high level when RS and RW are jointly low level When readable busy signal, when RS is writable data when high level RW is low level；

6th pin：E ends are Enable Pin, and when E ends are by high step-down, liquid crystal mode performs order；

7th~14 pin：D0~D7 is 8 bi-directional data ends；

15th~16 pin：Empty pin or the back of the body lamp power supply.15 instep light positive poles, 16 instep light negative poles；

Single-chip microcomputer P0 mouths drive liquid crystal display.

Specific operation process is as follows：

As shown in Fig. 2 after user sweeps Quick Response Code, obtaining into lobby needs to pay how many money information, and user is by carrying Show payment, by wireless network transmissions, after payee receives deserved money, send unlocking cipher short message to the list for specifying door Piece machine, i.e. payee instruct transmission password short message to pass through GSM network to TC3iGSM modules with AT（Including SIM card）, single-chip microcomputer leads to Cross serial ports and read encrypted message, after single-chip microcomputer is compared with the password being stored in, if both compares essentially equal opened Door.
