PRINCIPLES AND FUNCTIONING OF ELECTRONIC LOCKING SYSTEMS
Electronic locking systems are composed of four functional parts. These parts can be together or as separate modules. The first part of the code system, which consists of electronic key and reader for him or the keypad for dialing code. The second part is the management center, which hosts some details of the codes and compares this information with pre-entered in her right of access to relevant code and password. The third part is locking element. This is electromechanical element that carries out lock, and through signals from the ruling center is unlocked or locked. The fourth part of a power system that can be networked - 220V, battery combined - 220V and battery. There is also the fifth part, which in principle is an option. It is the interface and liaise with computers or other devices.
Advantages of electronic locking systems are:
- High reliability and security of mechanical milling because no visible benchmark part to locking mechanism;
- High reliability and security of the code;
- Manage an unspecified number of locks with a single electronic key;
- High vandal stability;
- Comfort and practicality;
- Control access;
- Track events and access to the system.
Depending on the type of management, electronic locking systems are contact type and proximity. Management is through code and keyboard or by electronic key, which may take various forms - cards, key ring, key.
In electronic locking systems lock is carried out by electromechanical Lockable element (lock), which may be elektromagnetic strike, electromagnetic lock, electromechanical lock. This Lockable element removed through electrical signal ship Lockable or go (rough) or language. He has no externally visible part, often inside. In closed door can not understand his position, which will be carried out how to attack against him, unlike mechanical locks.
Electronic locking systems have two types of structures - united and divided. United systems have been implemented in two versions. In the first version codes and managing part are united in a single module, and supplying part and conclusions are part separately. Under the second option all parts - Part code governing part of supplying and lock mechanism are united in one common module. Distributed systems consist of three parts - the code part, locking part and general management center, each of them alone in a separate module.
Electronic locking systems control access to the premises. At any one time the owner can easily prohibit or allow access to a key to different doors. Some systems have memory for events in themselves and remember events that happened - what, when, how often and where it's unlocked, the lock, entered, and went out.
