Embodiment:

Below in conjunction with accompanying drawing the utility model is described further:

By shown in Figure 1; This kind is based on the home security warning system of GSM SMS module; Comprise a STC12C5A60S2 single-chip microcomputer, its unique distinction is: said system also comprises some RE200B type Thermoelectric Infrared Sensor, RS232 serial ports, HRH type GSM modulator-demodular unit, Siemens TC35 module and ZIF connector; Wherein, The data output end of said some Thermoelectric Infrared Sensor is connected to the corresponding I/O interface of single-chip microcomputer respectively, and said HRH type GSM modulator-demodular unit is done bidirectional traffic through the RS232 serial port with the UART serial ports of said single-chip microcomputer respectively with Siemens TC35 module and is connected; Be connected with the ZIF connector on the said Siemens TC35 module.

Fig. 4 is the hardware structure diagram of the related single-chip microcomputer of the utility model.This programme adopts the STC12C5A60S2 single-chip microcomputer; The STC12C5A60S2/AD/PWM series monolithic is the single-chip microcomputer of the single clock/machine cycle of macrocrystalline science and technology production; Be high speed/low-power consumption/superpower jamproof 8051 single-chip microcomputers of new generation; The compatible fully tradition 8051 of instruction code, but the fast 8-12 of speed is doubly.The special-purpose reset circuit of inner integrated MAX810,2 road PWM, 8 tunnel 10 A/D conversions at a high speed, to Electric Machine Control, the strong jamming occasion.It has low-power consumption, ultralow valency, at a high speed, highly reliable, antistatic by force, the strong anti-interference and characteristics that can't decipher.Need not to connect crystal oscillator and reset circuit when using the STC12C5A60S2 single-chip microcomputer to make minimum system, make minimum system simpler.Comprise module such as R/C oscillator and external crystal oscillator circuit in central processing unit, program storage, data-carrier store, Timer, UART serial ports, serial ports 2, I/O interface, high-speed a/d conversion, SPI interface, PCA, house dog and the sheet in the STC12C5A60S2 single-chip microcomputer.All required unit modules during the STC12C5A60S2 series monolithic has almost comprised data acquisition and controlled.

This programme selects for use HRH GSM Modem to communicate.This module can be received and dispatched note under the control of single-chip microcomputer, realize long-range short run data transmission by note, voice call, and the number arq mode is realized functions such as wireless real-time data communication and wireless Internet access.

Antitheft induction pick-up in this programme is selected RE200B type Thermoelectric Infrared Sensor for use.This is because infrared ray is a kind of light, is a kind of in numerous invisible rays in the sunray, has the character of normal optical, can be with light velocity rectilinear propagation.Thermoelectric Infrared Sensor is a kind of new type of high sensitivity detecting element that grew up in the 80's.It can detect the variation of the infrared energy of human body radiation with the noncontact form, and converts thereof into voltage signal output.This voltage signal is amplified, just can drive various control circuits.RE200B adopts TO-5 packing forms to be shown in the following figure operate as normal DC voltage 3-10V; Signal output voltage minimum value 2.5V, representative value 4V; The maximum 250mV of noise output voltage, representative value 90 mV, frequency response 0.3Hz-3Hz, gain ± 10Bb.This sensor investigative range is looked squarely angle 138 degree, looks up angle 125 degree.

TC35 module in this programme is the main function components at terminal; Partly form by GSM BBP, power supply special IC, radio circuit and flash memory etc.; Be responsible for handling audio frequency, data and the signal in the GSM cellular device, embedded software section is carried out the function of application interface and all gsm protocol stacks.BBP has comprised all modulus functions of cellular radio part, for satisfying the growing demand in GSM/ PCS phone user market, under without the situation of external circuits, just can support FR, HR and EFR voice and chnnel coding.Radio frequency part realizes that based on transceiving chip SMARTi the antenna cable in the module is connected to the connector of 50 Ω of GSC type.The TC35 module is adapted at developing under the minimum power GSM cellular device, and this cellular device applying portion constitutes man-machine interface, can insert TC35 through serial ports.TC35 connects the cellular application part through 40 core ZIF, and the ZIF connector provides control data, the application interface of sound signal and power supply line, and the TC35 terminating circuit is as shown in Figure 2.

The pinouts of TC35 module TC35 as shown in Figure 3 has 40 pins, draws through a ZIF connector.These 40 pins can be divided into 5 types, i.e. power supply, data I/O, SIM card, COBBAIF and control.The 1st～14 pin is a power unit, and wherein 1～5 is the supply voltage input end, and 6～10 is power supply ground GND, 11,12 charging pins, and 13 external output voltages, 14 is ACCU.TEMP connects the thermistor of negative temperature coefficient; 24～29 is SIM card pin, is respectively CCIN, CCRST, CCIO, CC CL K, CCVCC and CCGND; 33～40 are used for the handle of answering the call for speech interface; 15,30,31 and 32 pin are control section, and 15 is ignition lead IGT, after TC35 energising, must give one of IGT greater than the 100ms low level; Module just starts; 30 is R TCbackup, and 31 is Power down, and 32 is SYN C; 16～23 bit data I/O are respectively DSR0, RIN G0, RxD0, TxD0, CTS0, R TS0, D TR0 and DCD0.

Because native system only uses the receiving short message function, therefore only use the data input/output interface of TC35.It should be noted that TC35 connects as data communications equipment (DCE), and connect as data terminal equipment (DTE), the RXD of the corresponding single-chip microcomputer of the RXD0 of TC35, the TXD of the corresponding single-chip microcomputer of the TXD0 of TC35 unlike general modulator-demodular unit.The TC35 data-interface is operated in CMOS level (2.65V), and single-chip microcomputer carries out level conversion to control and the signal of communication of TC35.The transmitting-receiving of Chinese and English information can be realized in this terminal under independently developed software, its speed can freely be selected between 1. 2k～115kbit/s.Most of mobile phones on the market all support to be similar to the GSM AT instruction set of Mo2dem control now; This instruction set is the GSM system development by producers such as Nokia, Ericsson, Motorola and HP jointly, has wherein comprised the control to SMS.Control to SMS has three kinds of realization approach: Block Mode, based on the Text Mode of AT order with based on the PDU Mode of AT order.TextMode is fairly simple, and many moneys Nokia mobile phone is all supported this pattern.The mobile phone of Siemens is only supported PDU Mode mostly, and PDU Mode is a kind of method of sending or receiving mobile phone short message, and the short message text is transmitted through behind the hexadecimal code.The reception short message is mainly sent with PDUMode in this terminal.

During concrete the realization, at first, the terminal is linked to each other with the computer serial port through RS232.Then, open hyper terminal, select the direct serial mouth to connect, port parameter is made as 19200bit/s, no parity check, data bit 8, position of rest 1.Click the call button on the hyper terminal tool bar, input AT and carriage return if OK then shows the successful connection of computing machine and mobile phone, at this moment just can be imported all kinds of GSM AT and instruct on the screen.

Use native system, change, will send alerting signal, thereby guarantee that a distant place can receive a crime report through the GSM network in case RE200B type Thermoelectric Infrared Sensor has been sensed indoor temperature.
