Abstract
The utility model discloses a novel decoding-resistant remote control device, which comprises a hand-held remote control device which is provided with a releasing signal-transmitting device, a controlling host machine which is provided with a releasing signal-receiving device, and a signal transmitting device which is matched with the controlling host machine and is used for transmitting a confirmation signal thereto, wherein the signal transmitting device is connected with the controlling host machine by a signal transmitting wire. The novel decoding-resistant remote control device has the advantage that after being locked, even if the controlling host machine is illegally decoded, the remote control device can not be unlocked until receiving a correct confirmation signal transmitted by the signal transmitting device. Therefore, compared with the traditional decoding-resistant remote control device, the novel decoding-resistant remote control device has better security.
Description
Technical field
The utility model relates to the wireless remote control decoding technique, specifically a kind of novel anti-decoding telechiric device that is used for remote control control gears such as vehicle anti-theft warning device, electric lock, power window.
Background technology
At present, common beeper is made up of telepilot and main control system.Telepilot is made up of encode an integrated circuit and signal transmission circuit and power supply, and main control system is made up of receiver amplifier, decoding integrated circuit, mu balanced circuit, operating circuit.Mu balanced circuit provides working current for each circuit, and receive the signal that amplifying circuit receives the telepilot emission and after power amplification, send decoding integrated circuit to, if information code is correct, decoding circuit instruction works circuit then, topworks's work.If the information code mistake, then alarm mechanism is carried out in the decoding circuit instruction.
In the nearly stage, a kind of demoder at beeper has appearred in market, utilizes this demoder to carry out illegal decoding to beeper, thereby implements the theft vehicle or open the automatic door and window stealing of entering the room.In view of beeper easily by the deficiency of illegal decoding, design and a kind ofly prevent to utilize the telechiric device of demoder illegal decoding to seem very necessary.
The utility model content
The purpose of this utility model is to overcome above-mentioned defective, and a kind of anti-decoding of radio telechiric device of anti-decoding is provided.
The utility model adopts following technical scheme: a kind of novel anti-decoding telechiric device, comprise hand-held remote controller that is provided with the ring off signal emitter and the main control system that is provided with the ring off signal receiving trap, also comprise one suitable with described main control system, as to be used for sending to main control system confirmation signal sender unit, this sender unit is connected with described main control system by signal transmssion line.
Described sender unit comprises fingerprint identification device and produces the affirmation signal generation device of described confirmation signal according to this fingerprint identification device.
Described sender unit also can comprise the acoustic control recognition device and produce the affirmation signal generation device of described confirmation signal according to this acoustic control recognition device.
Described sender unit comprises electric door lock that is provided with contactor and the affirmation signal generation device that produces described confirmation signal according to above-mentioned electric door lock.
Establish the decoding integrated circuit IC that has confirmation signal detection pin in the described main control system, described sender unit is connected with the affirmation input pin of this decoding integrated circuit IC by signal transmssion line.
By above-mentioned description to the utility model structure as can be known, compared with prior art, the utlity model has following advantage:
After locking, main control system need receive ring off signal simultaneously and correct affirmation signal just can be unblanked, even main control system, does not have correct affirmation signal by illegal decoding, also can't unblank, so the utility model is compared with traditional telechiric device and is had better security.
Description of drawings
Fig. 1 is the block diagram of the anti-decoding of the utility model remote control fingerprint identification device;
Fig. 2 is the block diagram of the anti-decoding of the utility model remote control acoustic control recognition device;
Fig. 3 is the block diagram of the anti-decoding of the utility model remote control electric door lock device.
Embodiment
Embodiment of the present utility model is described with reference to the accompanying drawings.
Embodiment one
With reference to Fig. 1, a kind of novel anti-decoding telechiric device comprises hand-held remote controller 1 that is provided with ring off signal emitter 11 and the sender unit 3 that is provided with the main control system 2 of ring off signal receiving trap 21 and is provided with confirmation signal generation device 31.
Establish the decoding integrated circuit IC 22 that has confirmation signal detection pin 221 in the main control system 2, the affirmation signal of sender unit 3 is connected with the affirmation input pin 221 of described decoding integrated circuit IC 22 by signal transmssion line 4.
The ring off signal emitter 11 of hand-held remote controller 1 sends ring off signal, sender unit 3 sends confirmation signal to main control system 2, main control system 2 receives and detects the ring off signal of hand-held remote controller 1 emission and the affirmation signal that sender unit 3 sends, and above-mentioned main control system 2 is controlled in ring off signal, confirmation signal acting in conjunction.
With reference to Fig. 1, shown in topworks 5 specifically be a kind of in the remote control control gears such as vehicle anti-theft warning device, electric lock, power window.Described topworks 5 is connected with described main control system 2 and carries out the instruction of main control system 2.
Above-mentioned sender unit 3 comprises fingerprint identification device 32 and produces the affirmation signal generation device 31 of described confirmation signal according to this fingerprint identification device 32.Fingerprint identification device 32 is used to receive and identify the person's of unblanking finger print information; Confirmation signal generation device 31 sends confirmation signal by signal transmssion line 4 to main control system 2.
Embodiment two
With reference to Fig. 2, the structure of present embodiment and the foregoing description one is basic identical, and the key distinction is that the sender unit 3 in the present embodiment comprises acoustic control recognition device 33 and produces the affirmation signal generation device 31 of described confirmation signal according to this acoustic control recognition device 33.
Embodiment three
With reference to Fig. 3, the structure of present embodiment and the foregoing description one, embodiment two is basic identical, and the key distinction is that the sender unit 3 in the present embodiment comprises electric door lock 34 and confirmation signal generation device 31.
In the time of after locking, will removing, in hand-held remote controller 1 sends the ring off signal certain hour, need sender unit 3 to send confirmation signal.Two signal actings in conjunction, anti-decoding telechiric device just can come into force.After anti-decoding telechiric device is locked, the main control system 2 of telechiric device was by illegal decoding even should anti-ly decode, but the correct affirmation signal that short of sender unit sends just can't be unblanked, so the utility model is compared with traditional anti-decoding telechiric device and had better security.
Above-mentioned only is embodiment of the present utility model, but design concept of the present utility model is not limited thereto, and allly utilizes this design that the utility model is carried out the change of unsubstantiality, all should belong to the behavior of invading the utility model protection domain.
