What is ACCESS CONTROL SYSTEM
ACCESS CONTROL SYSTEM, and then call the discrepancy
management control system( the ACCESS CONTROL SYSTEM). It is the
digitization management system that a kind of manager pass in
and out. The familiar control at gate system have: The password
control at gate system, get in touch with the IC card( the
respond type IC card) control at gate system not, the palm a
living creature of the fingerprint iris identifies the control
at gate system generic name of etc.. The password control at
gate system because of it of safety is weak is bad to have
already face to eliminate with convenience, the living creature
identifies the control at gate system safety high, but the cost
is high, because of refusing to know the rate and saving
capacity etc. application the bottleneck problem but did not get
the extensive market approbation. The nations of now are most
popular and the most in general use to still get in touch with
the IC card control at gate system not. Get in touch with the IC
card not because of its higher safety, best and convenient and
sex prices compare the main current of become the control at
gate system.
The control at gate system constitute parts of control at
gate systems to be read that the card machine goes out the
pushbutton lock to have the 讯 to gather the line machine
intelligence card power supply management software to constitute
by the control at gate controller.
Intelligence card: In the intelligence control at gate
function that system is in the middle is act as to write in to
read the data lies the quality. Currently essential technique:
Mifare, EM, and Legic etc., speak up from the applied angle, the
card is divided in to read the card and read and write the card
only; Speak up from the material and features, and then is
divided into the thin card, thick card, abnormal shape card.
Read the card machine: Be responsible for read card of data
information, and deliver the data to the controller. Speak the
different and technical card and read the card machine towards
should be different technically generally, use the Mifare card
and will use the Mifare to read the card machine for example.
Controller: Is the whole core of system, be responsible for
the input of the whole system information data and handle, save,
output, controller with read that the communication method
between the card machine all adopts the R485, R232 and a format
of Wergen's generally.
The lock have: It is a performance parts within the whole
system. Have the three major type currently: The electricity
lock, magnetic force lock, give or get an electric shock to put
the lock. Carry on choose to go together with according to the
request of the customer and the material of the door,
electricity lock use for the wood door generally, magnetic force
the lock used for the metals door, the wood door, the
electricity puts the lock opposite to say that the application
compare extensively, the door of various material all can use.
Be used as to carry out the parts, the stability, enduring that
locks is very important.
Power supply: The power supply equipments is a count for much
part in the whole system, if the power supply chooses to go
together with not appropriate, appear the problem, the whole
system will paralyze or appear the fault, failure of various
each kind, but allow the multi-user and usually will neglect the
importance of the power supply. The control at gate system all
chooses to use the linear power supply of compare the
stabilization generally.
Manage the software: Be responsible for works such as the
whole system supervision, management and search etc.. The
manager can pass to manage the work circumstance of software to
the whole state, controller of system to carry on the
supervision management, and can expand to complete to cruise
more, test frequently, the parking lot management etc. function
The control at gate system classification
1 Offline control at gate, is a machine son to manage a door,
can't carry on the control with the computer software, also
can't see the record, carry on the control through a controller
directly. The characteristics is the price cheapness, installing
the preventive maintenance in brief, can't look into the record,
is not suitable for the amount of number precious sight more 50
or the place that personnel usually flow( usually point someone
go into job and leave office), is also unsuitable for a quantity
precious sight more 5 of engineering.
2 485 online control at gates, is to carry on the control at
gate type of the communication with computer, the direct usage
software carries on the management, including the card and
affairs controls. So have the management convenience, control
concentration, can look into the record and carry on to the
record analytical processing with used for other purposes. The
characteristics is a price higher, install to support an
enlargement, but the training is in brief, can carry on test to
wait to increase in value the service frequently. The in keeping
with person is many, mobility big, an engineering for have
another.
3 Control system of TCP/ IP, also call the ether online
access control system also is can with the control at gate
system of the online, but carry on the net of online to the
computer and controller through the network line. In addition to
having 485 all advantages of the control at gate online nets,
still have the speed sooner, install more in brief, the online
quantity is larger, can across the region to across the city
line perhaps. But the existence equipments price is high,
needing the computer network knowledge. In keeping with install
in main category eyes, the number quantity have another, to
speed have engineering of request, crossing the region.
4 The fingerprint control at gate system, is a control at
gate equipments that replaces the card through a fingerprint to
carry on the management, have the similar to 485 characteristic,
but have the better safety, the weakness is the number quantity
less of the register, passing the speed slow.
