Two-dimensional information photoelectric lock

Abstract

The invention relates to a two-dimensional information photovoltaic lock, and belongs to the technical field of lock sets. When a key card information hole (5) is detected by a photovoltaic level sensor (3-1), an LED light source (8) is lighted up, light irradiates on a data collecting window baffle plate (7) at the same time, and a light ray irradiates on a card type key (1) at the back of a data collecting window (14) through the data collecting window (14); a light spot falls on the surface of a dember effect two-dimensional positioning device (15), V<CD> and V <AB> are outputted, and the voltage signals separately represent a y coordinate and an x coordinate; the set of the voltage signals is amplified by a signal amplifier and is changed into digital signals through A / D conversion, and the digital signals are transmitted into a single chip microcomputer; comparison and recognition are performed on the data and the data in a two-dimensional digital information characteristic database, and if the data is matched with pre-stored data in the two-dimensional digital information characteristic database, an instruction of opening the lock is sent. According to the two-dimensional information photovoltaic lock disclosed by the invention, the security is good, the own fingerprint information of a user cannot be divulged, so that the privacy is effectively protected; exquisite patterns can be printed on the card type key (1), so that the two-dimensional information photovoltaic lock has a favorable market potential.

Description

technical field [0001] The invention relates to a two-dimensional information photoelectric lock, belonging to the technical field of locks. Background technique [0002] It is an indisputable fact that China has become the world's largest producer and consumer of locks. At present, the annual sales of the domestic lock industry has reached more than 40 billion yuan, the production capacity has exceeded 2 billion sets, and the annual export volume has exceeded 10 billion yuan. According to the forecast of relevant experts, in the future, my country's lock market will continue to grow at a rate of more than 20% per year. [0003] From the perspective of industry development, the product quality of lock factories across the country varies, especially because most lock products have low technical content, less investment, and are easy to imitate, resulting in a large number of fake and fake products. Many domestic high-end locks are imitating the West, lacking national elemen...

Problems solved by technology

But this kind of lock also has disadvantages: one is that the camera is exposed and easily damaged

In addition, the two-dimensional light point information can be easily copied by using the silica gel inverted film; second, the more two-dimensional light point information input into the computer, the lower the safety factor, and there are errors in recognition; the third is that the price of this lock is expensive; Fourth, the structure is complex and prone to failure, and the installation is cumbersome

The retina pattern control lock invented by Ruitu is similar to the two-dimensional light point information lock. This kind of lock is recognized by the arrangement of blood vessels in the retina at the bottom of the human eyeball. Therefore, when eye diseases or blood vessels are congested or ruptured, the computer will not lock the lock. Identification has more disadvantages than two-dimensional light point information locks, and the price is also very expensive

There is a fatal flaw in all these methods of using body physiological structure for identification, because all the physiological information of a person (two-dimensional light point information, palm prints, retina, etc.) parameters are the highest privacy for a person, such information is It cannot be disclosed. If the locks generally use physiological information to unlock, it will cause the leakage of the highest personal privacy, which implies a great hidden danger, and may cause great loss of personal property and life.

[0005] Although modern smart locks still have their own defects, their subversive design to traditional locks makes them have a broad space for development
