Entrance guard controls a system to go up oneself 80 time begin the century arisen, as a result of its technology practical get very quickly developing quickly, ban safety administration to use mechanical key means all the time with front door here, but as the day of economy and society profit grows, simple entrance guard safety manages the need that already cannot satisfy a society far, product of a kind of simple electronic entrance guard begins to appear. Primary entrance guard system is independent magnetic card system merely, can get stuck with process designing or hold process designing implement undertake install and administrative, later the rapid development as the computer, entrance guard controls a system to begin to manage and be controlled by the computer gradually, entrance guard system also controls the computer control that develops a network by individual entrance guard, the administrative function of entrance guard also grow in quantity of with each passing day, systematic security is increasingly perfect.
System of today's online network entrance guard uses the computer already extensively management of the control central, entrance guard controller uses intelligence distributed processing technology, network communication uses the means such as RS-485/422 bus line, TCP/IP, long-range modem extensively, the administrative function of entrance guard software is more powerful also.
We notice the maturity that controls a technology as entrance guard and development, entrance guard system got all-time and wide application is mixed gain ground, regard safe domain as one of 3 much (entrance guard, monitoring, call the police) entrance guard system is not isolated system, need develops ceaselessly and rise, satisfy the development need of safe domain diversity.
We will introduce 3 kinds of new-style entrance guard systems and technology below: Control of entrance guard of ＋ of system of control of wireless entrance guard, all classical warning function is not had seam compositive, entrance guard to control ＋ Lou Yu to be not had to telling seam compositive.
One, wireless entrance guard controls a system
One of main functions of entrance guard system are to pass a network to undertake control and transmission information, the entrance guard system in the past is to use wired cable means to transmit with communication, but the limitation of the limitation that installs a place as a result of entrance guard and execution condition, often cannot use wired means to come true in some places, and used system of wireless entrance guard to break afore-mentioned limitation, american KERI company is newest the new development that the system of KRF wireless entrance guard that rolls out in the world indicates the technology develops a wireless entrance guard.
Characteristic of performance of system of KRF wireless entrance guard:
The price with lower ※ (with wired system use cable and construction cost compare) ;
