Look at the smart door lock technology applied to locks yesterday, today and tomorrow

Locks are closely related to our lives. It relates to the security of each family, unit and public place. With the rapid development of economy, professional lock products of various styles, materials, structures and functions emerge in endlessly. With the rapid development of key industries such as residential buildings, automobiles, middle and high-end office buildings and hotels in China, and the growing demand for highly protective lock products in defense, public security, and financial systems, high-end locks have a promising market.

Page 1: The password lock, the most primitive smart lock talking about security, I am afraid we are the first to think of security monitoring equipment, whether it is a variety of forms, or different characteristics. All bring more convenience to people. However, in addition to security monitoring, there are actually quite a few devices that also have many features and types. Inadvertently, people guard people's safety in silence. Among them, smart locks are such a model.

With the continuous development of smart locks, its own technology is undergoing a series of replacements. Then in the process of change, different smart technologies have their own advantages. What needs have been solved for everyone? Let's take a brief look at the different smart electronic door locks, what are their respective specialities.

Password lock, the most original smart lock talking about password lock, can be said to be the earliest and most primitive kind of smart lock. In use, the user can complete the control of the gate by entering the corresponding password of the gate only when it needs to be opened. However, with the continuous advancement of technology, such locks have also experienced a rich development. At present, in the general category of code locks, there are common code locks formed by simple electronic circuits, as well as coded locks having high defense performance based on integrated circuits. Of course, for the moment, the most widely used is a comprehensive coded lock that takes the integrated circuit as its core and controls it through manual programming.

In fact, talking about the advantages of the code lock, compared to the mechanical lock is certainly not a little higher. For the user in use, the user's password can be changed at any time to prevent the password from being stolen, and at the same time, the password insurance factor can also be avoided because the number of people entering and leaving is too large. When the password is entered many times wrong, the alarm system will automatically start, so that the security of the door lock will not be reduced because of the long use time.

However, password locks also have very obvious disadvantages in use. For example, passwords are easily stolen by people and the password keyboard is at risk of being damaged or destroyed. For users, there are problems with password forgetting and troublesome operations. Therefore, this is also where the password lock is in the application and hinders the trust of the user.

Page 2: Induction card lock, the most common access control insurance card lock, the most common access control insurance talking about the card lock, I am afraid we will not feel strange. Regardless of whether it is a hotel or an ordinary residential building, almost all of these IC card-based access control systems are used. As to why the IC card type access control is such an audience, I am afraid that it is due to the IC card's strong confidentiality and low-cost manufacturing process. So in a very long period of time, have been everyone's favor.

In the history of proximity cards, it can be divided into two types, namely contact IC cards and contactless IC cards, which we have done in detail before. Also, since the contact area of ​​the contact IC card is often exposed on the surface of the card and is therefore more easily copied by people, the current proximity card is more often accomplished with a more convenient and secure contactless card.

Compared with the contactless IC card, the non-contact card can effectively avoid damage to the card due to external friction. At the same time, there is no direction in use. Therefore, it can be more convenient to use. In addition, in authentication, most of the current cards use multiple password protection, and in some key areas, IC card can also use non-stored password confirmation function, so in terms of security, than ordinary passwords More stable.

Of course, the IC card-type door card is not seamless, its high cost, and the uniqueness of its use has also brought a lot of confusion to users and manufacturers. However, in terms of security, it can be said that it has long been a leader in civilian security.

Page 3: Fingerprint recognition, ready to usher in a new era of fingerprint identification, ready to usher in a new era With the recent rapid development of biotechnology, fingerprint identification is also more applied to our lives. Whether it is a fingerprint attendance machine or a fingerprint verification lock, it has long been common in our lives. However, if smart door locks are introduced into biometrics, there is no doubt that smart door locks can be brought into a new era.

In fact, for the security of the fingerprint identification lock, we certainly do not need too much to repeat. If this technology can be used very well, it can almost be said that the security identification has been promoted to the highest level. However, although the fingerprint identification algorithms currently used on PCs are relatively mature, there are still relatively large development opportunities for the algorithms used on various embedded systems. Since the available processing resources and memory resources are limited in an embedded system, when fingerprint algorithms are migrated to an embedded system, a compromise must be made between the recognition performance and the use cost. Therefore, an embedded fingerprint identification algorithm is required. The development has become one of the difficulties in the development of fingerprint products. So, although fingerprinting provides us with almost the highest level of protection, we still need more time and patience if we really enjoy mature security.

The above is the smart door lock technology we applied yesterday, today, and tomorrow. Although there are many technical bottlenecks in current applications and R&D, we may need more patience. However, with regard to the future of intelligent security technology, we can fully expect from the heart with a positive attitude.

With the advancement of society, science and technology, and culture, the security of mechanical locks has become increasingly inadequate to meet the needs of the people. Looking into the future of the fingerprint lock market, there is a big trend in the fingerprint lock home. It will gradually replace the traditional clumsy mechanical locks and become a new force in our home security.
