Embodiment Construction

[0014] The control method of the automobile laser remote control door lock of the present invention includes signal generation, signal reception and signal decoding confirmation.

[0015] The signal is generated by the laser emitting device (1), and the single-chip coder (2) that modulates the laser beam through the digital coding in the device. When the single-chip microcomputer is working, the driving circuit is connected with the output terminal of the laser, and the encoder emits the output signal (3) through the laser. Thus, signal generation is achieved.

[0016] The reception of the signal is through the modulated laser receiver (4), which converts the received laser signal into a photoelectric conversion signal that can be recognized by the single-chip microcomputer, connects the signal to the single-chip decoder (5), and compares the received and sent data. number of positions. If the positioning numbers are consistent, a correct command will be generated, and the c...

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 [0001] The invention belongs to the technical field of automobile supplies, and relates to a laser remote unlocking device for an automobile security system, which uses laser as an information carrier and can prevent intruders from interfering with lasers of other wavelengths or laser sources with different codes. Background technique [0002] At present, most cars use wireless remote control to unlock, adopt fixed code encryption technology, and output corresponding signals through the pairing state of password address bits between special encoding and decoding chips. This traditional encryption technology uses address bits to program different key quantities through different combinations of three-state encoding chips. The multi-bit address data password for transmission and reception is fixed by the manufacturer, and the security performance of the system is improved by the method of multi-group arrangement and combination of variables. Although most car ...
