First, the similarities and differences of the unlocking method
1. Card key type electronic lock: Its characteristic is to use the card key to unlock, the card key is the organic component lock of the control circuit. Cards that make keys are diverse in nature, such as magnetic cards, punch cards, and the like. The control circuit is usually designed to operate normally without power consumption.
2, electronic key electronic lock: its characteristics is the use of electronic key plating, electronic key is an important part of the control circuit. The electronic key consists of a unit circuit made up of components and is made into a small handheld unit type. The connection between the electronic key and the main control unit can be various methods such as sound, light and electricity.
3, according to the control electronic lock: its characteristic is to use the button method to unlock, simple and convenient, this is a common lock method used by electronic locks.
4. Dial-type electronic lock: Its characteristic is to use the dial method to unlock, and many push-button electronic locks can be transformed into dial-type electronic locks.
5, touch-type electronic lock: the use of contact method to unlock, easy to operate, compared to the button switch, the contact switch has a long service life and low cost.
Second, according to the use of components and similarities and differences
1. Relay type electronic lock: Select the contact linkage of the relay. The electronic lock cooperates with the series and parallel combination of various switches for coding control.
2, thyristor type electronic lock: select serial, parallel thyristor for encoding.
3, single knot tube delay type electronic lock: the use of single knot tube as the unlock delay device, increased the security function of the electronic lock.
4, electronic code switch: the use of analog integrated switch block, cooperative combination switch for coding control.
5, circuit type electronic lock: the 555 time base circuit is connected into a trigger and other methods, cooperative combination switch for coding control. Dedicated security integrated circuit type electronic lock. As the center of the electronic lock control circuit, the special security lock integrated circuit has high integration degree, strong function, few external components, and convenient and reliable device.
Electronic lock selection recommendation
1. Normally unlocked: If the magnetic lock is completely embedded by a group of electromagnetic coils, the E-shaped iron core is energized to generate a magnetic field, and the other half is a suction plate. When the suction plate and the E-shaped magnet are closed, a closed magnetic field is formed. This produces a closing magnetic force that acts to lock the door. Another example is the electric plug lock, which generates a magnetic field suction force when the solenoid valve coil is energized to move the electromagnetic valve core to close, so that the mechanical linkage portion is driven to extend the lock tongue. As soon as the power is turned off, the lock is unlocked immediately, which meets the safety requirements.
2, normally closed: usually locked by the mechanical part, through the work of the solenoid valve or the drive of the motor to move the lock sheath, and then turn the handle part to unlock. Generally, the driving of the motor is the driving mode of the lock sheath, that is, there is a lock sheath hole on the rotating wheel, the handle is normally in a free state, the handle can be rotated but cannot be unlocked, and when the electronic identification part passes the verification, the motor rotates the drive lock. The sheath enters the rotating hole, and the handle can be unlocked by turning the handle.
First, the electronic lock purchase should pay attention to the combination of its function and the environment of application.
According to the use of the environment, the need for function is determined in the hotel, the unit, the office building or the family. Because the different operating environments have different functional focuses. Hotel use, room handling should be in line with the hotel's standard handling, as a hotel electronic door locks, it is necessary to have the function: for all the key cards need to have time-constrained functions, locks have open door record function, have a hierarchical function .
Second, the electronic lock purchase should pay attention to its safety and stability.
Door locks (mechanical and intelligent) are the first to be safe and stable as a safety precaution. Security can be measured in two ways: one is to guard against hoaxes and deliberate tactics such as jealousy and drilling. In the mechanical lock and the electronic door lock, as long as the RF card electronic door lock is a fully enclosed layout, its safety is also optimal. Second, the defense skills are open, and the ability to open the mechanical locks is very poor. Regardless of the layout of the mechanical lock can be opened by other means. The key can be copied and there will be great security risks. In the electronic door lock, the magnetic card is easy to be copied because there is no code constraint. IC cards and RF cards have completely solved the problem of open defense skills.
The Electric Steam Wallpaper strippers is the most productive, safest and easiest to use steam wallpaper stripper.
The Wallpaper Stripper force steam through the layers of paper, helping to not only remove the paper but also glue residue from walls.The Wallpaper Steam Stripper is particularly effective on stubborn papers with paint on, or wood chip paper.
The 3L, 4.5L ,7L Electric Wallpaper Remover Stripper is much easier, compared to soak and scrap off the wallpaper manually, it only uses water which is heated.
Once the water boil then the water evaporates, produces steam out of the plate. The steam will penetrates into the wallpaper and loosen the old adhesive paste, so the wallpaper can then be pulled off and removed easily.
