working principle
After the ordinary lock is disassembled, you can see that the upper side is the slot---the direction of the key back, and the other side is a row of small holes. The small holes are copper pillars of different lengths and the springs are sealed with aluminum on the outside. Usually the copper pillars pop out half because they are not stressed, which prevents the rotation of the large copper core. When the corresponding key is inserted, the copper pillar and the teeth on the key contact to form a regular curve, and the gap on the large copper core is flashed away, enabling it to rotate. The principle of turning the lock to open is relatively simple.
The intelligent lock system is composed of an intelligent monitor and an electronic lock. The intelligent monitor supplies the power required by the electronic lock and receives the alarm information and status information sent by it. Line multiplexing technology is used here, so that the power supply and information transmission share a two-core cable. The smart lock uses card swiping, fingerprint, face swiping, and password input to open the door. Each door opening method has a common The feature is that you don’t need to bring a key when you go out. After the smart lock is installed, you only need to enter the fingerprint, face, and password. The program in the home smart lock will record the entered data. When it is sensed that there is data input from the outside, the program will Automatic comparison, if the comparison is correct, it will send a command to the motor in the smart lock to open the smart lock. The program in the home smart lock will record the entered data. When it is sensed that there is data input from the outside, the program will automatically compare. If the comparison is correct, it will send a command to the motor in the smart lock to open the smart lock. Improve the reliability and safety of the system.
Internal structure
For example, ordinary door locks, sliding door locks, cross-type door locks, etc. Although their styles, structures, and sizes are different, the unlocking principle is exactly the same. The reason why these lock unlocking principles are exactly the same is that their lock cores are all round objects. The smart lock coil is sealed in the card, which is not easily affected by the outside and has a longer service life; there is no mechanical contact between the radio frequency card and the reader, which avoids various failures due to contact reading and writing. It adopts electronic components such as imported motor micro-switches, and its performance is stable and reliable.
safety technology
Smart locks have more advantages than mechanical locks. From the perspective of safety, they are safer than mechanical locks and more convenient to use than mechanical locks. Smart lock The smart lock with the anti-theft alarm function replaces the traditional mechanical lock, which overcomes the disadvantage of poor safety performance of the mechanical lock, and greatly improves the smart lock both in technology and performance. With the development of large-scale integrated circuit technology, especially the advent of single-chip microcomputers, smart locks with microprocessors appeared. In addition to the functions of electronic locks, they also introduced functions such as intelligent management, touch sensor recognition, and data storage. , So that the smart lock has high security and reliability, and its application is increasingly widespread.
The following is a more intuitive comparison of the advantages and disadvantages of mechanical locks and smart locks
Advantages and disadvantages of mechanical locks
The price is relatively low; the market awareness is high; the panel is relatively strong; the high-quality mechanical lock has better intelligent anti-theft performance; the anti-technical opening ability is high, the security is high, and you are not afraid of forgetting to bring the key. Ordinary mechanical locks have low anti-opening ability; keys are easy to lose or even be copied; daily forgetting to bring keys will cause inconvenience; prices are generally higher; market awareness is low; civilian smart locks generally have mechanical emergency keyholes, which are safe Loopholes.
Advantages and disadvantages of smart locks
Smart locks refer to locks that are different from traditional mechanical locks and are more intelligent in terms of user identification, safety, and management. Smart locks are made using electronic technology, integrated circuit design, a large number of electronic components, and a variety of innovative identification technologies. Smart locks generally require electricity or batteries to work, and if there is a power failure, the smart lock cannot be opened or closed. Therefore, the state stipulates that civilian smart locks should be equipped with emergency mechanical keys. The emergency key is generally an ordinary mechanical pin lock, so the smart lock can also be opened technically, and the security is correspondingly reduced.
