Owing to adopt as above technical scheme, the utlity model has following superiority:

Weak point at present product exists at first adopts leading in the world rolling coding and decoding technology, and it has the each random rolling variation of password, and repetition rate is 1,600,000,000 times/one, never can be decrypted.Have and self learn/wipe memory function, main frame and telepilot need not prior pairing, as long as an optional telepilot that adopts rolling coding, click study in the main frame decoding circuit/wipe button, press any button of telepilot in 5 seconds, can finish pairing work.Press aforesaid operations, anyone can add the telepilot number easily according to demands of individuals at any time.If take place that telepilot is lost or during stolen situation, only need press study in the decoding circuit/wiped button 15 seconds, circuit just can be wiped all the elements in the memory, next as long as just can not match use again with losing telepilot by the operation of above-mentioned increase telepilot.

Described remote-controlled intelligent telephone automatic alarm device except that above functional characteristics, also have anti-plunder and domestic medicine emergency function, prompting removing function, alarm function, exempt from telephone set separate, stored number function, be not afraid of power down high-quality voice direct-read-after-write function in 20 seconds, prevent cutting the telephone wire function, high loudness warning threatening function.

For realizing exempting from telephone set separate, stored number and dial feature, to adopt the telephone set special chip, and designed the periphery dialing and the speaking circuit of standard, dialing is rapid, and dialing tone is accurate, lamprophonia.

For realizing not being afraid of in 20 seconds power down high-quality voice direct-read-after-write function, use American I SD14 series voice module, have high-quality recording in 20 seconds, be not afraid of power down, voice messaging still can be preserved more than 30 years after the power down, direct-read-after-write.

For realizing prompting removing function and the high loudness alerting signal of sending 120 decibels, external controlled high loudness alarming horn and stabilized voltage supply zoarium have been designed.External purpose one is in order to increase the disguise of main frame, the 2nd, and for the ease of selecting favourable sounding position.Stabilized voltage supply inside is provided with overcurrent and overheating protection element, can guarantee trouble free service all the year round.

For realizing anti-trimming function, polarity switching after, connect a current-limiting resistance and steering diode to the RB6 mouth from positive pole, just often this mouthful be high level, is low level during the trimming generation, the single-chip microcomputer state and the internal processes of mouth is thus finished this function.

For realizing all control function, the design's core has adopted the U.S. PIC of MICOCHIP company series monolithic, and this single-chip microcomputer has that volume is little, and logic is accurate, and is low in energy consumption, the characteristics that driving force is strong.And inside is provided with " house dog ", is aided with rational program, can have suitable antijamming capability.In program, pass through detection, not only finished above-mentioned control function, also realized functions such as anti-robbery, medical treatment are sought help, alarm the level state of each I/O mouth.

Below in conjunction with the description of drawings specific embodiment:

Fig. 1 is the emitter circuit block diagram of remote-controlled intelligent telephone alarm.

Fig. 2 is the reception decoding processing circuit block diagram of remote-controlled intelligent telephone alarm.

Fig. 3 is the Single-chip Controlling treatment circuit block diagram of remote-controlled intelligent telephone alarm.

Realize that best way of the present utility model is: the radiating circuit in the accompanying drawing one is used casing device separately, make telepilot and carry by the user.The reception decoding circuit of accompanying drawing two, three, exclusive telephone chip circuit, 20 seconds playback circuits and single chip machine controlling circuit are made on the circuit board, use a casing device, as main frame.With external stabilized voltage supply in the accompanying drawing three and high loudness loudspeaker one casing device, be connected with main frame, for main frame power supply and be subjected to the host computer control sounding.

In the rolling code radiating circuit shown in the accompanying drawing one, the pin that the TH150 chip meets switch S 1, S2, S3, S4 when static is high level, when pressing a certain button, the pin of this button correspondence becomes low level, the coded signal that the high-low level of TH150 output simultaneously changes.

In the rolling code receiving circuit shown in the accompanying drawing two, four output pins of TH151B are low level when static, after input pin receives coded signal, through the internal processes computing, four output pins wherein pin output high level in short-term give single-chip microcomputer.

In the single chip machine controlling circuit shown in the accompanying drawing three, the RA0-RA3 mouth of single-chip microcomputer is the input high-impedance state when static, and RB0, RB1, RB2, RB3, RB4, RB5 are low level, and RB6 is a high level.When single-chip microcomputer when the RA0-RA3 mouth receives high level signal, RB0 becomes high level and realizes automatic off-hook, RB1, RB2, RB3 mouth become high level successively and realize dialing automatically, and the RB4 mouth becomes high level and plays voice, and the RB5 mouth becomes high level driving alarming horn and pipes.If the RB6 mouth becomes low level, single-chip microcomputer then enters anti-trimming alarm condition.

At first the lead-in wire of the phone on the main frame is connected on the telephone wire during use, and connects the stabilized voltage supply line.Carry out the pairing, three groups of telephone numbers selecting of input user, typing alarm content voice of telepilot and main frame, the work that the door magnetic inductor is installed then.So far, can carry out the use of following function:

1, home security: press the warning key once (non-quiet) or twice (quiet) on the telepilot when user leaves home, system just enters on the alert.This moment is if door is opened, the door magnetic ejector is transmitted to main frame with enabling signal, the host computer control alarming horn pipes in 7 seconds and does to remove prompting for 7 times, if be not disengaged, main frame was just carried out alert program after 7 seconds: alarming horn pipes (or quiet), dials phone number automatically and sends the emergency voice messaging.(three groups of telephone number circulations are dialed twice).

2, the anti-robbery and the medical treatment emergency: when house robbery or urgent illness emergency take place, can press the emergency button once (non-quiet) or twice (quiet) on the telepilot, this moment, main frame was carried out alert program immediately: alarming horn pipes (or quiet), dials phone number automatically and sends the emergency voice messaging.(three groups of telephone number circulations are dialed twice).

3, in warning, emergency, the arbitrary process of warning, as long as telephone wire broken string situation takes place, main frame is controlled alarming horn at once and is yowled incessantly, until releasing.

4, external different probe such as infrared probe, the quick probe of cigarette, pressure probe etc., can be realized the automatic warning function of infrared antitheft, fire prevention, overload etc.
