Embodiment

To combine accompanying drawing and specific embodiment that the utility model is done further explanation below:

As shown in Figure 1, based on the home security warning system of GSM SMS module, comprise MCU circuit, sensor circuit, gsm module circuit, circuit for remotely controlling and power circuit in the present embodiment.The MCU circuit input end is connected with sensor circuit, and the signal of sensor sends the MCU circuit to; The MCU circuit is communicated by letter with user mobile phone through the gsm module circuit, sends detected sensor signal to user mobile phone through the gsm module circuit; User mobile phone is communicated by letter with circuit for remotely controlling through the gsm module circuit simultaneously, again through circuit for remotely controlling and MCU circuit communication, sends order to the MCU circuit and realizes Remote.MCU circuit, sensor circuit, gsm module circuit, circuit for remotely controlling all link to each other with power circuit to guarantee that the cut situation of external power source can operate as normal.

Used sensor circuit comprises infrared sensor circuit, gas leakage sensor circuit, smoke transducer circuit in the present embodiment; Said infrared sensor circuit, gas leakage sensor circuit, smoke transducer circuit all link to each other with the MCU circuit.

Used gas leakage sensor circuit be except detecting CO in the present embodiment, NO, and N02,02, outside the gases such as S02, can also detect the oxysome integration number in the blood.

The gsm module circuit selects for use HRH GSM Modem to communicate in the present embodiment; GSM engine of the embedded high reliability of HRH GSM Modem (GSM Cellular Engine) and 51 SCM systems (MCS51); Standard serial interface frees the user with the software interface agreement of simplifying from numerous and diverse GSM communication standard is resolved and debugged; Easy to use; And the data transmission of public network has communication range wide (the GSM network covers the whole nation basically), transmits characteristics such as stable, reliable.The gsm module circuit need carry out the central number setting before use:

With the Beijing area is example, and sms center number is :+8613800100500, should issue Frame to GSM MODEM:

AA 09 2B 38 36 31 33 38 30 30 31 30 30 35 30 30 (16 system data)

If success is set, GSM MODEM replys AA 09 "+8613800100500 ", if be provided with unsuccessfully, GSM MODEM replys after AA 09 ' ERROR ' sms center number is provided with, and is kept on the SIM card, only needs to be provided with once; Also can after number setting sms center on the mobile phone, reinstall GSM Modem, just need not be provided with again later.

Remote control cloth in the present embodiment, withdraw a garrison and select 315M amplitude modulation telepilot for use.

Keyboard, LED demonstration, ferroelectric memory and real-time clock link to each other with control of realization time and SMS through embedded 51 SCM systems (MCS51) among interface and the said HRH GSM Modem in the present embodiment.

Keyboard adopts HD7279 as the keyboard display driver in the present embodiment.

What MCU circuit (microcontroller) was selected for use in the present embodiment is the AT89S52 single-chip microcomputer.

As shown in Figure 2, after system worked on power, each module was carried out initialization, read real-time clock and judged whether clock equals timing.Then send note to designated mobile phone if clock equals timing, system starts working; If being not equal to timing, clock then judges the present duty dress attitude or withdraw a garrison state of deploying troops on garrison duty.If system is in the state of withdrawing a garrison and then continues to read real-time clock and judge; If system be in the state of deploying troops on garrison duty then the MCU circuit just begin to inquire about each sensor and whether have signal to spread out of; Do not read clock if there is signal then to return; Then send the mobile phone that corresponding note is given appointment if there is sensor to spread out of, let user's very first time specify situation about increasing the weight of, take appropriate measures.

As shown in Figure 3, read key assignments under the situation that system can externally interrupt, key, preset key, reset key help recovery routine during through the school.

DS12887 as shown in Figure 4 adopts the CMOS technology to process, and crystal oscillator and the outside lithium battery interlock circuit required clock chip combine in chip internal.Adopt the clock circuit of DS12887 chip design not need any peripheral circuit and have good microcomputer interface.Advantages such as the DS12887 chip has little horizontal bar in the front of a carriage used as an armrest consumption, peripheral interface is simple, precision is high, working stability is reliable can be widely used in the various real-time clock occasions that need degree of precision.Its major function is following:

1. include a lithium battery, powering-off state operation obliterated data not more than 10 years.

Meter second, branch, the time, sky, week, day, the moon, year, and the leap year compensate function is arranged.

3. binary numeral or binary-coded decimal express time, calendar and locking.

4.12 hour or 24 hours systems, 12 hours clock modules have PWM and AM guidance, and the daylight-saving time function is arranged.

5.MOTOROLA5 select with the INATAEL bus timing.

6. 128 ram cells and software sounder are arranged, wherein 14 114 bytes are general RAM as byte clock and control register, all ARAM cell datas all have power-down protection.

7. square-wave signal output able to programme.

8. look-at-me is exported (IRQ) and bus compatible, and locking interruption, periodic interruptions, clock update cycle end interrupt can also can be tested respectively respectively by software masking.

Time and calendar information obtain through reading corresponding internal memory byte, and time, calendar and timer clock are through writing setting of corresponding internal memory byte or initialization, and its byte content can be the decimal system or BCD form.Time can be selected 12 hours systems or 24 hours systems, and when selecting 12 hours systems, a hour byte high position is represented PM for logical one.Time, calendar and locking byte are double bufferings, and be always addressable.When p.s., these 10 bytes were walked 1 second, check one time the locking condition, as when upgrading, read time and calendar possibly cause mistake.The locking byte of three bytes has two kinds of method of application.First kind, when the locking time write when corresponding, branch, second locking unit, regularly allow, under the condition of alarm clock position high level, locking interrupts punctual starting every day once.Second kind, in three locking bytes, insert one or more sign indicating numbers of being indifferent to.Being indifferent to sign indicating number is any 16 system numbers from C to FF.When hour byte be indifferent to the code position position time, because a phase line hour and a minute locking byte are put when being indifferent to, the per minute locking is once in order hour to take place once for locking; All put when being indifferent to when three bytes, per second interrupts once.

The above only is the preferred implementation of the utility model; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model design; Can also make some improvement and retouching, these improvement and retouching also should be regarded as in the utility model protection domain.
