Abstract
The invention relates to a method for controlling an automobile laser remote control gate lock. The method comprises the steps of generating a remote control signal, receiving the signal, and decoding and determining the signal. A remote control signal device takes the laser as an information carrier wave so as to prevent an intruder from using other laser or different coded laser to interfere. The device combines a laser technology with a digital coding technology to generate cipher control with high secrecy and overcome the shortages that the traditional wireless remote control locking is easily interfered by different frequencies. Through the characteristics of height directional property, strong interference resistance and long emitting distance, and the like of the laser, the device can prevent the interference of the intruder.
Description
Technical field
The invention belongs to the Automobile Products technical field, the laser remote-controlled unlocking apparatus that relates to a kind of automobile safety-protection system, be a kind of with laser as information carrier, can prevent the device that the invador uses the lasing light emitter of the laser of other wavelength or different coding to disturb.
Background technology
Present most automobile adopts wireless remote control to unblank, and adopts the fixed code encryption technology, by the password address bit pairing state between the special Code And Decode chip, exports corresponding signal.This traditional encryption technology is that the various combination of address bit by ternary coding chip come the different key amount of layout.The multidigit address date password that transmits and receives is fixing by producer's establishment, improves the security performance of system by the method for many groups permutation and combination variable.Though present most automobile remote-control device encryption technology adopts the fixed code formula, its Secret key amount is limited, makes confidentiality very poor.
When meeting when existing strong interference environment or attempt invador to use on every side to enter radiowave cloth defence area and aim at wireless receiver with equifrequent, its coding chip is normally encoded, but decoding chip can not be exported signal accurately.The warning system main frame just can not produce automatic warning, makes the security deficiency of wireless remote-control system, and safety-protection system loses due effect.Property safety to the car owner has huge hidden danger like this, and the use of existing controlled in wireless automobile door lock is extremely unsafe.
Summary of the invention
Continuous improve current of science and technology, the range of application of laser remote control system has been applied in the military communication system also in continuous expansion.Deficiency at the security of existing wireless remote control automobile door lock, design a kind of laser remote-controlled unlocking apparatus, this laser that utilizes can overcome the unblank shortcoming that is subject to disturb of existing wireless remote control as the device of information carrier, utilize the single-chip microcomputer digital coding simultaneously, on the inherently safe basis of modifying device, with the laser remote-controlled mode Control of Automobile door lock of high precision, promoted the anti-theft capability of automobile greatly.
The present invention is achieved by the following technical solutions:
Constitute by laser beam emitting device and laser receiver during laser remote-controlled unlocking apparatus.Laser beam emitting device comes the single-chip microcomputer scrambler of modulating lasering beam by constructing numerical coding, carries out output signal and comes drive laser work, thereby realize utilizing digitally coded information to carry out the transmission of short-distance and medium-distance as information carrier with laser.
Laser receiver comprises modulated laser pick-off, by amplifier laser signal conversion and the amplification that receives become photosignal, be connected with the single-chip microcomputer demoder, the data of reception and the data of transmission are positioned number relatively, if the data locking unanimity that receives will send right instructions; If locate inconsistently, will send false command, thereby reach the purpose of remote-control unlocking.
The present invention has the following advantages:
1, utilizes laser as information carrier, make the present invention have characteristics such as good directionality, antijamming capability is strong, transmitting range is far away.
2, adopt numerical coding that laser beam is modulated, utilize the uncontinuity of laser, more increased the antijamming capability of this device, improved serviceable life and reliability, reduced use cost, safe and reliable.
3, device have simple in structure, volume is little, characteristics such as easy to carry.
Description of drawings
Fig. 1 is the integrally-built synoptic diagram of laser remote-controlled door lock of the present invention, and this figure double as is a Figure of abstract.
Among Fig. 1: 1-laser beam emitting device, 2-single-chip microcomputer scrambler, the signal that 3-produces, 4-laser receiver, 5-single-chip microcomputer demoder.
Embodiment:
The control method of vehicle laser remote control gate lock of the present invention comprises the generation of signal, the reception of signal and the decoding affirmation of signal.
The generation of signal is to be produced by laser beam emitting device (1), comes the single-chip microcomputer scrambler (2) of modulating lasering beam by the numerical coding in the device.When single-chip microcomputer was worked, driving circuit was connected with the output terminal of laser instrument, and scrambler is launched output signal (3) by laser instrument.Therefore, realized the generation of signal.
The reception of signal is by modulated laser pickoff (4), and the laser signal that receives is converted to and can this signal be connected with single-chip microcomputer demoder (5) with the photoelectric conversion signal of single-chip microcomputer identification, relatively receives and send the location number of data.If the location number unanimity will produce right instructions, automobile door lock can normally be opened or close; If location number is inconsistent, will send false command.
The present invention utilizes digital coding that device is carried out self improvement, produces the cipher control of high level security; The laser that utilizes high precision is as information carrier, overcome the shortcoming that wireless remote control unblanks to be vulnerable to the interference of different frequency, thereby prevented that the invador from disturbing it, ensured car owner's property safety greatly.
Claims (4)
1. the control method of a vehicle laser remote control gate lock is characterized in that comprising the dispensing device of laser signal and the generation device of laser signal.
2. the described sender unit of claim 1 is characterized in that: the generation of signal is to be produced by laser beam emitting device, comes the single-chip microcomputer scrambler of modulating lasering beam by the numerical coding in the device.When single-chip microcomputer was worked, driving circuit was connected with the output terminal of laser instrument, and scrambler is launched output signal by laser instrument.
3. the described signal receiving device of claim 1, it is characterized in that: the reception of signal is by modulated laser pick-off, and the laser signal that receives is converted to and can by amplifier it be amplified with the photosignal of single-chip microcomputer identification.Signal is connected with the single-chip microcomputer demoder, relatively receives and send the location number of data.If the location number unanimity will produce right instructions, automobile door lock can normally be opened or close; If location number is inconsistent, will send false command.
4. according to right 2 described laser beam emitting devices, it is characterized in that: utilize laser as information carrier, have short transverse, antijamming capability is strong, transmitting range is long.
