Description

Composite barcode lock

The invention relates to a composite barcode lock, in particular to a lock recognition technology which can increase the coding capacity density and the difficulty of password cracking.

According to the lock industry, the locker has applied advanced technologies such as sound, light, electricity, magnetism and wave to locks, such as electronic card locks, magnetic locks, ultrasonic locks, infrared locks, remote locks and photoelectric locks. Although the above-mentioned locks can improve the anti-theft security compared with the conventional locks, most of the above-mentioned conventional structures use signals such as sound, light, electricity, magnetic waves, etc., and form corresponding binary digit codes according to the result of the generation or absence of the above signals. Due to the linear coding method, the number of groups available for coding and the collocation change are not large. Therefore, when the commercial application is used, the occurrence of code repetition is more likely to occur, and thus it is easier to be cracked. In addition, since the QR code is already a mature application technology, the field of application technology is becoming more and more extensive, and its coding capacity density is huge, and it is not easy to cause a code repetition situation when it is commercialized, and thus it is less likely to be cracked. Therefore, the related art has applied a one-dimensional barcode or QR code to the lock, and the related patents are as follows:

By emitting light to the bar code pattern, a signal corresponding to the patterning is received and reflected, and the signal is converted and decoded by a microprocessor to control whether the solenoid valve is turned on or not. Although the patent has the unlocking function of the photoelectric and key mechanism, since the light-emitting element adopts a fixed light source intensity setting, the light sensing element can only sense that the light source is bright or off to form a corresponding binary digit code, thus The number of coding groups is not very variable, and it is easy to be solved when the commercialization is used, so it is easy to be cracked, resulting in the failure of the security anti-theft mechanism and the damage caused by property damage.

2.
