Intelligent Entrance Guard System

Intelligent entrance guard and safety management system is a new

type of modern safety management system, which combines the

microcomputer automatic identification technology with the modern safety

management practices into an organic whole. It contains lots of new

technologies such as the electronic, mechanical, optical, computer

technology, communication technology, biotechnology, and so on. It is an

effective measures to achieve the goal of implementing safety management

at the inward and outward of important departments. It can be applied to all

kinds of confidential departments, such as banks, hotels, generator

rooms,the armory, confidential rooms, offices, intelligent communities,

factories etc. With the rapid development of digital technology and network

technology today, access control technology finally gets the good chance to

develop rapidly. Entrance guard system has far transcends the pure doorway

and key has gradually developed into a set of complete

access management system.

1 The Development of Entrance Guard System

Inward and outward entrance guard system just as its name implies is a

control system of managing the inward and outward channels, which is

developed on the basis of the traditional door lock. The traditional

mechanical lock is just a simple mechanical device, so no matter how

reasonable the structural is designed, how strong the material is made,

people can always open it through various means. Key management is very

troublesome in places like offices and hotel rooms where so many people

entering and leaving the passageway. Whenever the keys are lost or

employees are replaced, locks and keys must be renewed. In order to solve

these problems, electronic card lock and electronic trick lock are invented.

These two kinds locks’ appearance raised the management level of inward

and outward channels from a certain extent and has impelled the channel

management to enter the electronics era. But with the continuous

application of these two kinds of electronic locks, the defects of themselves

are gradually exposed. The problem of magnetic card lock is the easy

replication of the information, a greater degree of wear between card and

card reader, high failure rate and low safety factor. The problem of

combination lock is that the password is easy to leak and we do not have

even any small clue to investigate with, so the safety coefficient is very low.

At the same time, it is easy to be unlocked by people outdoor because most

of the reading card (password) and the control part is installed together

outside the door at this period. Entrance guard system in this period have

remained in its early immature stage, so the entrance guard system is usually
