GSM engine (GSM Cellular Engine) and 51 Single Chip Microcomputer (SCM) system (MCS51) due to the HRH embedded high reliability of GSM Modem, user is resolved from numerous and diverse GSM communication standard and frees debugging by standard serial interface and the software interface agreement simplified, easy to use, and the transmission of the data of public network has the wide (GSM of communication range
Network covers the whole nation substantially), the features such as transmission is stable, reliable.Therefore the design selects HRH GSM Modem to communicate.Its major function is that a. receives and dispatches note；B. the transmission of long-range small lot data is realized by note；C. voice call (GSM phone) d. number arq mode realizes wireless real time data communication；E. (automatic-answering back device type) is got online without being tethered to a cable.Module requires that 12V/500mA powers, and passes through serial communication, baud rate 9600bps with computer or single-chip microcomputer, installs SIM by SIM card holder.
For theft-proof sensor, native system uses active infra-red opposite type sensor, and it is released infrared sensor relative to traditional passive type heat and has the advantage that
The most active correlation infrared sensor is installed on door and window and all need the position set up defences, uses multiple beam comprehensive descision, when the barrier having certain volume blocks, is just triggered, greatly reduces the wrong report of sensor；
2. be arranged on the positions such as door and window due to it, the normal activity making owner at night is unrestricted, and this provide the user the possibility deployed troops on garrison duty great night.
In order to send the function of short message when realizing system generation alert to the number specified, then keyboard and LED must be had to show, guard against theft and alarm system is carried out telephone number and presets, the design selects HD7279 to drive as keyboard & display.
During in order to realize occurring alert, the time that alert occurs is carried out record, and in order to ensure the reliability service of system, it is desirable to system carries out self-inspection timing reporting system running status, it is therefore desirable to system has real-time clock function.The design selects DS12887 real-time timepiece chip.
Can be changed the cloth of system, disarming state before entering defence area or after leaving defence area to realize user, the design has selected 315M amplitude modulation remote controller, and this remote control appliance has the advantage that
1. it is operated in amateur band, need not spend to buy frequency；
2. coverage is remote, typically up to 2001000 meters；
3. there is abundant address code to select for user, due to application on remote controller and remote control plate
The PT2262/PT2272 codec chip codec state to all providing 8 tri-states, say, that have the 8 power address codes of 3 to be available for user and select, it is sufficient to the burglar alarm cloth of all users, application of withdrawing a garrison in meeting community.
In order to prevent due to accidentalia alternating current power supply power-off, system allows for continuing properly functioning a period of time after alternating current power supply is cut-off, native system uses the lead-acid accumulator of 12V/7AH as back-up source, and this just proposes a problem continuing to solve to system design: be exactly the charge power supply problem of management of accumulator.Due to lead-acid accumulator electrolyte meeting generating gasification phenomenon under overcharge conditions, cause the service life reduction of accumulator, accumulator is when fully charged, the voltage of accumulator is probably at about 13.6V, when under-voltage, voltage is probably at about 10.9V, according to this feature, I finds that this charge-discharge characteristic meets the transmission characteristic of hysteresis loop comparator, the upper limit threshold of hysteresis loop comparator will be set to 13.6V, lower threshold is set as 10.9V, after fully charged, make hysteresis loop comparator control relay and charging current limiter resistance is switched on bigger current-limiting resistance；When discharging into 10.9V, hysteresis loop comparator controls relay and is switched on less current-limiting resistance by current-limiting resistance, and safeguards system running current is less than the electric current filling charging circuit soon, and more than the electric current of trickle charge charging circuit.In thus can guarantee that the hysteresis band that hysteresis loop comparator always works in 10.9V 13.6V, i.e. ensure that accumulator is the most under-voltage and do not overcharge.
In order to realize the storage to presetting number of cell phone and the record to warning message, native system have employed the ferroelectric memory that ensure that power failure data is not lost, such memorizer has many advantages relative to traditional EEPROM: the most traditional EEPROM write number of times is limited, generally 100,000 times, and ferroelectric memory has almost limitless erasable characteristic；2 traditional EEPROM writing speeds are relatively slow, it is generally required to the time of the several NOP of CPU time delay etc. are to be written, and ferroelectric memory has the speed of operation identical with RAM；3.EEPROM needs bigger energy to complete the most erasable, and ferroelectric memory belongs to Micro Energy Lose when write.The design has selected FM24C16 to be used as non-volatile data memory, its feature is as follows: 1. FM24C16A is a kind of serial non-volatile memory, its structural capacity is 512*8 position, interface mode is that industrial standard two wires manufactures serial line interface, feature operation to serial EEPROM is similar, having identical pin arrangements with EEPROM, difference is that FM24C16A has outstanding write operation performance；The internal employing of 2.FRAM reads Restoration Mechanism operation.So read-write number of times is based on row and column array arrangement with having read and write relation FRAM structure each time, row is defined by A8-A2.Access all can make a line reduce by a reading-writing life-span every time.The erasable number of times of ferroelectricity almost can be described as unlimited.Even if access per second 3000 times, using 10 years continuously, service life terminates not yet.
At least can reach following beneficial effect: overcome accidentalia alternating current power-off in prior art, limited phone is made to dial in crucial moment malfunctioning, Ethernet is faced with the hidden danger that circuit is cut-off equally, and be difficult to popularize, group system power consumption is very big, and network sets up and maintenance cost is the highest, and needs to buy fixing frequency, overcome owing to conventional alarm logging can not be checked, thus tight arrangement can not be made further to deploying troops on garrison duty.Avoid potential safety hazard, be independent of telephone and perform warning, and by the most reliably, the most ripe GSM mobile network, with Chinese short message or telephony modalities the most intuitively, directly the situation in warning place is reflected on mobile phone screen, allow antitheft more in time, use more convenient.
Last it is noted that the foregoing is only the preferred embodiments of the present invention, it is not limited to the present invention, although the present invention being described in detail with reference to previous embodiment, for a person skilled in the art, technical scheme described in foregoing embodiments still can be modified by it, or wherein portion of techniques feature is carried out equivalent.All within the spirit and principles in the present invention, any modification, equivalent substitution and improvement etc. made, within should being included in protection scope of the present invention.
