In today's society, "intelligence" is not limited to the human brain. Relevant researchers have begun to explore the intelligence of various machines and continue to penetrate into people's lives. Doors and windows as the first safety line of home, with the increasing awareness of people's safety, from the 1980s and 1990s, security doors and wooden doors gradually emerged. With the continuous development of security technology, nowadays with the emergence of smart door and window products, intelligence The door lock will become the "first patron saint" of family security. When buying a smart door lock, you should pay attention to the following points:

1. The appearance of the door lock is selected according to the user's hobby and decoration configuration. For example, the hotel recommendation is generally ideal for using a more elegant appearance.

2, using an empty hand or non-empty hand? According to years of use, no problem. It is recommended to use a non-empty rotary lock body. The non-empty rotary lock body is not affected by the deflection when the panel is installed.

3. Select the induction card door lock first to check its sensing sensitivity and then understand the static power consumption of the sensor door lock. Because the general sensor door locks are powered by dry batteries, it is important to understand the static power consumption of the sensor door locks. Some brand induction door locks are currently available. Four batteries can be used continuously for more than one year, and some brands change batteries in less than a month. Frequent battery changes can seriously affect the use.

4. When using the magnetic card door lock, you should know whether the door lock reader is self-developed by the manufacturer to read the card's own encryption algorithm, or use the universal magnetic card reader. If a card is written with a universal card reader, others can copy the card with a universal card reader and cannot achieve confidentiality. Keyu newly introduced ic card plus magnetic card door lock, guest card with magnetic card, administrator and maintenance information with ic card, magnetic card reader's card reader module own encryption algorithm.

5, the door lock presses the handle to open the door lock should be flexible and smooth, there should be no serious "åš“" and "å–³" mechanical friction sound in the lock body. With a light force, you can press the handle and press the handle back to normal. Mechanical transmission can not be fully lubricated by oil. It depends on the connection of mechanical parts. If the oil is fully lubricated, the door lock will fail frequently after the oil is dried for a long time.

6. Be sensitive when the door lock card or sensor key card. It is necessary to repeat the continuous card insertion or the induction key card to operate normally after opening the door. There should be no "no reaction" or "error" and "motor rotation" phenomenon. To investigate the information of the brand door lock is not easy to be confused, as long as the performance of the smart door lock is checked, the so-called additional functions do not necessarily have a practical effect. The door lock of the own error correction function circuit should be selected. If you choose an immature product, you may not be able to use it or maintain a lot of work. Keyu intelligent door lock circuit microcomputer chip control, the circuit comes with information error correction function, which makes the circuit processing information more stable. The sensor door lock adopts double clock correction error rate is very low, and the induction door lock uses wireless data collector for door lock maintenance. It is very convenient to collect the open door record data.

7. It is necessary to use the lock body of the standard five-lock tongue structure, and the lock body of the lock body should be driven by a motor. Keyu intelligent door lock body is improved on the basis of the original foreign famous brand lock body. The structure lock body has the highest domestic and external use rate, reasonable structure, low part wear, excellent performance, convenient installation and long service life. The normal service life is more than 15 years, and has been praised by users. The insurance tongue and anti-locking tongue have the functions of anti-insertion and anti-smashing. The square tongue (anti-lock tongue) is applied with a reinforcing structure to effectively prevent the square tongue from breaking or bending when the wind is blown or the door is closed when the door is opened. Keyu's improved reinforced structure of the square tongue is mostly concentrated on the tongue of the thickest tongue (12mm thick), and the distance of the force point is shortened so that the improved square tongue strength is five. More than double. The other brands use the original structure unmodified lock body to distribute a large part of the force to the weakest point of the tongue (3mm thick) position, the square tongue is too strong, the tongue tail is bent, the square tongue can not be fully back to the door lock Can't open it. Don't be misled by other so-called small locks or new locks, because the lock body is modified by the barely installed electronic control part of the structure of the household door lock. Because of the different use environment and the increased frequency of use, the lock is so strong. Poor physical performance and limited life.

8, the card is divided into ic card, tm card, magnetic card, proximity card, the most used now is ic card (contact type) and proximity card (non-contact) door lock, ic card door lock generally uses Siemens card (now has Shanghai Bay Ling, Fudan and other cards are compatible). Most of the inductive cards used in the proximity card locks use temic cards (many are called inductive ic cards, which can read and write data with a capacity of 33). The hotel sensor door locks generally make temic cards. Philips MF1 card (can be divided into multiple areas to read and write data function capacity of 1000 bytes, large capacity, card price and temic almost but the door lock price is much more expensive) a lot of consumption, attendance, open the card with mf1 card. There is also id card (id sensor card is a string of codes that have been set before leaving the factory, can only read information, can not write information into the card) id card is generally used in home, apartment smart lock without computer management system, the price of id card It is about half of temic card. At present, there are many companies that manufacture cards. Many smart lock factories use smaller card manufacturers to make cards, which cannot guarantee the purchase of chips (many parallel imports of electronic components) and packaging and pattern printing processes.
